Frequently Asked Questions (FAQ)

Q: Can the 6-146257-7 be used as a direct replacement for the 1-103240-7 in existing designs?

A: Yes. The 6-146257-7 maintains identical electrical and mechanical specifications, including pitch, position count, row configuration, contact type, current rating, and operating temperature range. PCB footprints and mating connector interfaces are compatible.

Q: What is the difference between the insulation materials used in these parts?

A: The 1-103240-7 uses thermoplastic insulation, while the 6-146257-7 uses Liquid Crystal Polymer (LCP). LCP provides enhanced thermal stability and mechanical strength, making it suitable for demanding applications.

Q: Why is the 1-103240-7 listed as obsolete?

A: Obsolete status indicates the manufacturer has discontinued production. The 6-146257-7 is the active equivalent and is recommended for all new applications and component sourcing.

Q: Are there compliance differences between these parts?

A: Yes. The 6-146257-7 is RoHS compliant and uses lead-free tin plating on posts, meeting current environmental regulations. The 1-103240-7 is RoHS non-compliant and uses tin-lead plating.

Q: What is the packaging difference?

A: The 1-103240-7 is supplied in standard packaging, while the 6-146257-7 is supplied in bulk packaging. Both are suitable for production environments.

Q: Are the contact finishes equivalent?

A: Both parts use gold-plated mating contacts with identical thickness specifications (30.0µin). Post plating differs: the 1-103240-7 uses tin-lead, while the 6-146257-7 uses tin. This difference does not affect electrical performance or interchangeability.
