Frequently Asked Questions (FAQ)

Q: Can the Amphenol 10142708-04000LF be used as a direct replacement for the Molex 1720651004?

A: Yes. Both connectors share identical pitch (0.224"), position count (4), row configuration (2), mounting type (through hole), shrouding (4-wall), termination (solder), and fastening mechanism (locking ramp). All critical mechanical and electrical parameters match, enabling direct substitution in board-to-cable/wire applications.

Q: What are the key differences between these two parts?

A: The primary differences are contact material composition (Copper vs. Copper Alloy), insulation material specification (standard LCP vs. halogen-free LCP), and operating temperature range specification. The Amphenol part provides halogen-free material certification and documented operating temperature range (-40°C ~ 105°C) with voltage rating (600VAC/DC), while the Molex part does not specify these parameters.

Q: Are there any compatibility concerns when switching between these connectors?

A: No compatibility concerns exist. Both connectors maintain identical mating pitch, contact geometry, shrouding configuration, and termination method. PCB footprints and mating interface dimensions are equivalent, allowing seamless substitution without design modifications.

Q: Which applications are suitable for both connectors?

A: Both parts are rated for automotive, industrial, telecommunications, and general-purpose applications. The Amphenol part additionally supports medical and military applications due to its halogen-free material specification and extended temperature range documentation.

Q: What is the significance of the halogen-free insulation material in the Amphenol part?

A: Halogen-free material specification indicates compliance with environmental and safety standards applicable to medical, aerospace, and certain industrial applications. This specification does not affect electrical or mechanical compatibility but may be required for specific regulatory or application requirements.

Q: Are both parts RoHS compliant?

A: Yes. The Molex part is ROHS3 Compliant, and the Amphenol part is RoHS Compliant. Both meet RoHS directive requirements for restricted substance elimination.
