Frequently Asked Questions (FAQ)

Q: Are all substitute parts electrically compatible with the primary part 0349852157?

A: Yes. All substitute parts maintain identical electrical specifications including connector type, contact type, number of positions, rows, mounting type, termination method, and operating temperature range.

Q: Does color affect mechanical compatibility?

A: No. Color is a cosmetic variation only and does not affect mechanical fit or electrical performance. All parts use identical insulation materials and fastening mechanisms.

Q: What is the difference between Bulk and Tray packaging?

A: Packaging format affects handling and storage but not component functionality. Bulk packaging is suitable for high-volume applications, while Tray packaging provides organized component arrangement.

Q: Can I substitute a part with different REACH status?

A: REACH status indicates regulatory classification but does not affect electrical or mechanical compatibility. Selection should be based on your specific regulatory requirements and supply chain compliance obligations.

Q: Are contacts included with these housings?

A: No. All parts in this series are housings only. Contacts must be sourced separately and crimped into the housing.

Q: What does MSL 1 (Unlimited) mean?

A: Moisture Sensitivity Level 1 indicates the component has unlimited shelf life and requires no special moisture control during storage or handling.
