141V and 141R 2.54mm Spring Terminal Blocks

141V and 141R 2.54mm Push-In Spring Terminal Blocks

This collection covers four product listings with 141V and 141R 2.54mm fixed PCB spring-terminal options. These are push-in or spring-clamp terminal blocks, not screw connectors. Mixed listings also contain 142-series 5.08mm and 7.62mm variants, which must be selected separately.

What Are 141V and 141R Terminal Blocks?

141-series products use a 2.54mm center-to-center pitch and a spring contact to retain the conductor. They solder directly to a PCB and do not use a removable plug-and-header interface. The family names describe two lead and wire-entry orientations:

• 141V: vertical or top-entry construction
• 141R: right-angle or side-entry construction

The V and R labels do not guarantee identical overall footprints. Compare the exact mechanical drawing before substituting one orientation for another.

Available Range

• 2.54mm pitch, equal to 0.1 inch
• 141V vertical/top-entry variants
• 141R right-angle/side-entry variants
• 2P through 10P across the dedicated 141 listing
• Selected mixed listings extending to 12P
• Packages of 10, 50 or 100 pieces depending on the listing
• Spliceable or modular construction stated for selected products

How to Select

1. Select a variant explicitly marked 141V 2.54mm or 141R 2.54mm.
2. Choose top-entry 141V or side-entry 141R according to PCB and enclosure access.
3. Select the required position count.
4. Confirm whether the listing supplies 10, 50 or 100 pieces.
5. Check the accepted conductor range and stripping requirements for that exact product.
6. Verify PCB-hole diameter, pin dimensions, body depth, wire-entry direction and adjacent-component clearance.
7. Confirm whether the chosen housing can be joined side by side; do not transfer a spliceable claim between listings.

141V vs. 141R

141V is typically selected when conductors approach from above the PCB. 141R supports side access near a board edge. Orientation affects assembly access and enclosure layout, and may also change pin placement and body geometry. Equal pitch alone does not prove that both versions can use one footprint.

Mixed-Pitch and Mixed-Family Boundaries

Three listings combine 141-series 2.54mm products with 142V/142R options at 5.08mm, and one also includes 7.62mm variants. Only 141V/141R options explicitly marked 2.54mm belong to this collection scope. A 142-series option is not a substitute for a 141-series footprint.

FFKDS, FFKDSA, FFKDS/V and FFKDS/H appear as family references or search identifiers. They do not prove original manufacture or cross-brand compatibility. Likewise, “Phoenix Contact” wording in a listing does not establish original Phoenix Contact manufacture.

Ratings and Conductor Data

The collection does not have one universal 150V/6A or 26–18AWG rating. The dedicated DG141 listing states 150V/2A. Another mixed listing states 300V/10A, while a separate mixed product title states 250V/10A and 22–14AWG. These values belong to their respective source listings and should not be transferred to every 141 variant.

Confirm the rating of the exact position count and orientation using traceable documentation. System limits also depend on conductor preparation, number of loaded poles, PCB copper, ambient temperature, contact temperature rise, creepage, clearance and applicable equipment standards.

Compatibility Boundaries

A 2.54mm pitch does not make these terminal blocks interchangeable with pin headers, female headers, KF128 screw blocks or another spring-terminal family. Match PCB drilling, pin geometry, body width, wire-entry angle and electrical documentation.

Typical Applications

When properly specified, compact 2.54mm spring terminals can support low-density field wiring, test fixtures, control and sensor boards, lighting controls and small electronic assemblies. Application examples do not establish Arduino, Raspberry Pi, industrial, mains or other platform compatibility.

Frequently Asked Questions

Are these screw terminal blocks?
No. The inspected products use push-in or spring-clamp conductor retention.

What is the difference between 141V and 141R?
141V is vertical/top entry, while 141R is right-angle/side entry. Verify their complete footprints before substitution.

Are all products exactly 2.54mm?
No. Several listings also contain 5.08mm or 7.62mm 142-series options. Select only variants marked 141V or 141R at 2.54mm.

Are all versions rated 150V/6A?
No. Published values differ significantly between listings, including a 150V/2A source value.

Can every housing be spliced to create a longer block?
Do not assume so. Confirm modular construction for the exact listing and orientation.

Are FFKDS-labeled products guaranteed to mate with another brand?
No. These are fixed PCB blocks, and family keywords do not prove dimensional or electrical equivalence.

Ordering Checklist

Confirm 2.54mm pitch, 141V or 141R orientation, position count, spring termination, package quantity, spliceable construction, conductor range, PCB footprint, ratings and supporting compliance documents.
