Frequently Asked Questions (FAQ)

Q: What determines if BTH-120-02-L-D-A can substitute for BTH-120-02-L-D-A-K?

A: Substitution is valid when all electrical and mechanical parameters are identical: 240 positions, 0.020" pitch, 2-row configuration, gold contact finish at 10.0µin thickness, 8mm mated stacking height, and surface mount technology. Both parts meet these criteria.

Q: Are there differences in compliance or certifications between these parts?

A: No. Both parts carry identical RoHS3 compliance, REACH Unaffected status, and MSL 1 rating. Regulatory acceptance is equivalent.

Q: Can these connectors be used interchangeably in PCB assembly?

A: Yes. Identical pitch, position count, row configuration, mounting type, and contact specifications ensure functional interchangeability in surface mount applications.

Q: What is the significance of the outer shroud contacts feature?

A: Outer shroud contacts provide mechanical guidance and polarization during mating operations, ensuring correct connector alignment on the circuit board.

Q: Does packaging format affect substitution eligibility?

A: Both parts are supplied in tube packaging. Packaging format does not affect electrical or mechanical compatibility.
