Frequently Asked Questions (FAQ)

Q: Can the 1744416-4 be used as a direct replacement for the DF7-4S-3.96C?

A: Yes. Both connectors share identical electrical and mechanical specifications: 4-position receptacle housings with 0.156" (3.96mm) pitch, female socket contacts, crimp termination, and latch lock fastening. The connectors are functionally equivalent for applications requiring these specifications.

Q: What is the significance of the product status difference?

A: The DF7-4S-3.96C is classified as obsolete, indicating discontinued production. The 1744416-4 is active, meaning it is currently manufactured and supported. This status difference makes the 1744416-4 the appropriate choice for new designs and ongoing component procurement.

Q: Are there differences in insulation material or operating temperature?

A: The 1744416-4 specifies polyamide (PA) nylon insulation and an operating temperature range of -55°C to 105°C. The DF7-4S-3.96C does not provide these specifications in available documentation. Both connectors maintain identical MSL 1 (Unlimited) moisture sensitivity ratings.

Q: Does the color difference between white and natural affect compatibility?

A: Color is a cosmetic attribute and does not affect electrical or mechanical compatibility. Selection between white and natural finishes depends on application-specific requirements or assembly standards.

Q: Are contacts included with these connector housings?

A: No. Both the DF7-4S-3.96C and 1744416-4 are supplied as housings only. Contacts must be procured separately and crimped into the housing according to manufacturer specifications.

Q: What compliance certifications apply to the substitute part?

A: The 1744416-4 is ROHS3 compliant and carries an ECCN classification of EAR99. Both connectors share the same HTSUS code (8536.69.8000) for tariff classification purposes.
