Compliance and Certification: Both parts maintain equivalent regulatory compliance:

ROHS3 Compliant
REACH Unaffected
UL94 V-0 material flammability rating
Moisture sensitivity level 1 (Unlimited)

Functional Equivalence: Electrical performance, mechanical fit, and environmental operating parameters are identical between the two parts. The substitute part includes a Board Lock feature and offers Through Hole mounting capability in addition to Surface Mount configuration, providing enhanced design flexibility without compromising compatibility.

Frequently Asked Questions (FAQ)

Q: Can the A-USB3 A-LP-SMT1 directly replace the A-USB3 A-LP-SMT1-R in existing designs?

A: Yes. Both parts are electrically and mechanically equivalent across all critical parameters including connector type, USB specification, contact count, current rating, operating temperature range, and termination method. The substitute part is active product status, ensuring continued availability.

Q: What is the difference between the main part and the substitute part?

A: The primary difference is product status: the A-USB3 A-LP-SMT1-R is obsolete, while the A-USB3 A-LP-SMT1 is active.
