Frequently Asked Questions (FAQ)

Q: Can QFSS-016-04.25-L-D-DP-A be used as a direct replacement for QFSS-016-04.25-L-D-DP-P?

A: Yes. Both parts are electrically and mechanically equivalent across all specified parameters, including connector type, position count, pitch, row configuration, mounting type, shielding features, contact finish, stacking heights, and compliance ratings. Direct substitution is supported without design modification.

Q: What are the critical parameters that determine substitution eligibility?

A: Substitution requires equivalence in connector type (Differential Pair Array, Female), position count (32), pitch (0.025"/0.64mm), row count (2), mounting type (Surface Mount), shielding and ground bus features, contact finish (Gold, 10.0µin thickness), stacking heights (11mm mated, 0.278" above board), and compliance certifications (ROHS3, MSL 1).

Q: Are there any packaging or handling differences between these parts?

A: Both parts are supplied in Tray packaging. MSL 1 rating applies to both, indicating unlimited moisture exposure tolerance. No special handling precautions differentiate these parts.

Q: What is the base product number significance?

A: Both parts share the base product number QFSS-016, indicating they belong to the same connector family within the Q2™ QFSS series. This confirms design compatibility and interchangeability within the series.

Q: Are both parts currently available?

A: Both parts maintain Active product status. Inventory levels may vary; consult current stock information for procurement planning.
