Engineering Selection Recommendations

The 6-146277-1 serves as the direct active equivalent for the obsolete 1-102976-1. Both connectors maintain identical electrical and mechanical specifications across all critical parameters including position count, pitch, contact configuration, current rating, and operating temperature range.

The primary distinction between these parts is product status and material composition. The 1-102976-1 is classified as obsolete, while the 6-146277-1 maintains active product status with current manufacturing support. The insulation material differs between thermoplastic (1-102976-1) and Liquid Crystal Polymer LCP (6-146277-1), with LCP offering enhanced thermal and chemical resistance properties. The post contact finish transitions from tin-lead to tin, reflecting modern RoHS compliance considerations in the substitute part.

Both connectors carry identical export classifications (EAR99) and tariff codes (8536.69.4040), confirming regulatory equivalence for procurement and logistics purposes.

Frequently Asked Questions (FAQ)

Q: Can the 6-146277-1 directly replace the 1-102976-1 in existing designs?

A: Yes. The 6-146277-1 maintains identical electrical and mechanical specifications across all critical parameters including position count, pitch, contact configuration, current rating, and operating temperature range. Physical dimensions and contact geometry are identical, enabling direct PCB-level substitution.

Q: What is the significance of the insulation material change from thermoplastic to LCP?

A: Liquid Crystal Polymer (LCP) provides superior thermal stability and chemical resistance compared to standard thermoplastic materials. This material upgrade enhances connector reliability in demanding thermal and chemical environments while maintaining compatibility with existing PCB designs and mating interfaces.

Q: Are there compliance differences between these parts?

A: Both connectors carry identical UL94 V-0 flammability ratings and EAR99 export classifications. The primary compliance distinction is that the 6-146277-1 reflects modern manufacturing standards with tin post finishes, while the 1-102976-1 uses tin-lead finishes. Both maintain equivalent electrical safety and regulatory status for their respective product lifecycles.

Q: Why is the 1-102976-1 classified as obsolete?

A: Obsolescence reflects the natural product lifecycle transition within TE Connectivity's connector portfolio. The 6-146277-1 represents the active continuation of this connector family with enhanced material specifications and ongoing manufacturing support.

Q: Are there inventory or lead time considerations for these parts?

A: The 1-102976-1 shows 701 pieces in stock as new original inventory. The 6-146277-1 shows 892 pieces in stock as new original inventory. Availability status should be confirmed with the supplier for current procurement timelines.
