Frequently asked questions
What is the closest pin-compatible alternative to 4-102977-0-39 in the AMPMODU Mod II series?
The series shares the same pitch and row spacing, so a different position count (e.g., 60 or 80 positions) can be used if the circuit count changes — the board pattern stays the same.
What compliance documentation does TE Connectivity provide for 4-102977-0-39?
RoHS/REACH compliance documentation is available from TE Connectivity on request — the contact post finish is tin-lead, so confirm the RoHS exemption status for the target market.
