Parameter Comparison

Engineering Selection Recommendations

Both TFC-150-02-L-D and TFC-150-02-L-D-A are active production parts from Samtec Inc. with identical electrical and mechanical specifications. Selection between these parts depends on application requirements:

TFC-150-02-L-D is suitable for applications where standard shrouded 4-wall construction meets design requirements without additional board alignment features.

TFC-150-02-L-D-A incorporates a Board Guide feature, providing enhanced alignment during mating operations. This variant is appropriate for applications requiring improved connector positioning accuracy or where board-to-board alignment is critical.

Both parts maintain ROHS3 compliance, UL94 V-0 flammability rating, and unlimited moisture sensitivity level (MSL 1), ensuring compatibility with standard manufacturing and storage protocols. Current inventory levels support both options for immediate procurement.

Frequently Asked Questions (FAQ)

Q: Are TFC-150-02-L-D and TFC-150-02-L-D-A electrically interchangeable?

A: Yes. Both parts maintain identical electrical specifications including 3.1A per contact current rating, 275VAC voltage rating, and phosphor bronze contact material with gold mating finish. They are electrically equivalent.

Q: What is the functional difference between these two parts?

A: The TFC-150-02-L-D-A includes a Board Guide feature not present in the TFC-150-02-L-D. This feature provides mechanical alignment assistance during connector mating but does not alter electrical performance or contact specifications.

Q: Can I substitute TFC-150-02-L-D-A for TFC-150-02-L-D in existing designs?
