Equivalent & Substitute Parts for 76345-306-40

Part Overview

The Amphenol ICC 76345-306-40 is a rectangular connector header, right-angle mounted, with 40 positions at 2.54mm pitch. This component is classified as obsolete, which necessitates identification of active equivalent parts for new designs and ongoing production requirements. The connector features through-hole solder termination, unshrouded design, and board-to-board connectivity in a 2-row configuration.

Substitute Part Grouping Explanation

Substitution eligibility for the 76345-306-40 is determined by strict equivalence in the following parameters: connector type (header), contact type (male pin), number of positions (40), number of rows (2), mating pitch (2.54mm), row spacing (2.54mm), mounting type (through-hole right-angle), termination method (solder), and fastening type (push-pull). All identified substitute parts meet these core electrical and mechanical requirements. Variations in contact finish, contact material, insulation material, and operating temperature specifications do not preclude functional substitution when these core parameters remain constant.

Engineering Selection Recommendations

The 76345-306-40LF is the direct successor within the Amphenol ICC BERGSTIK® series, maintaining identical mechanical and electrical specifications while transitioning to RoHS compliance and tin-only contact finish. This part is the primary recommendation for direct replacement in new designs.

The 2-826634-0 (TE Connectivity AMPMODU Mod II) provides full functional equivalence with enhanced specifications including gold-plated mating contacts, PBT insulation material, and extended operating temperature range (-65°C to 105°C). This part is suitable for applications requiring higher reliability or temperature performance.

The PS-40PE-D4LT1-PN1 (JAE Electronics PS series) offers functional equivalence with gold-plated mating contacts and PBT insulation. This part is classified as board-to-cable/wire style, providing flexibility for mixed connectivity applications.

All three substitute parts maintain RoHS compliance status, UL94 V-0 flammability rating, and MSL 1 moisture sensitivity classification. Selection should be based on supply chain availability, cost considerations, and specific application requirements regarding contact finish and insulation material properties.

Frequently Asked Questions (FAQ)

Q: Can the 76345-306-40LF directly replace the obsolete 76345-306-40?

A: Yes. The 76345-306-40LF maintains identical mechanical and electrical specifications including connector type, contact configuration, pitch, mounting type, and termination method. The primary differences are RoHS compliance status and contact finish composition (tin versus tin-lead).

Q: What are the key differences between the substitute parts?

A: The 76345-306-40LF is the direct Amphenol ICC successor. The 2-826634-0 offers gold-plated contacts and extended operating temperature range (-65°C to 105°C). The PS-40PE-D4LT1-PN1 provides board-to-cable/wire connectivity option with gold-plated contacts. All three maintain the core 40-position, 2.54mm pitch, right-angle through-hole configuration.

Q: Are all substitute parts RoHS compliant?

A: The 76345-306-40LF, 2-826634-0, and PS-40PE-D4LT1-PN1 are all RoHS compliant. The original 76345-306-40 is RoHS non-compliant.

Q: What is the significance of contact finish differences?

A: The original part features tin-lead finish. Substitutes use tin-only or gold finishes. Gold-plated contacts (2-826634-0 and PS-40PE-D4LT1-PN1) provide enhanced corrosion resistance and contact reliability. Tin-only finish (76345-306-40LF) meets RoHS requirements while maintaining functional performance.

Q: Can these parts be used interchangeably in existing designs?

A: Yes, provided the PCB footprint and mating connector specifications remain unchanged. All substitute parts maintain identical pitch, row spacing, and mounting type. Physical verification of connector compatibility is recommended before production implementation.

Q: What packaging options are available?

A: The 76345-306-40LF and 2-826634-0 are supplied in bulk packaging. The PS-40PE-D4LT1-PN1 is also supplied in bulk packaging. Verify packaging requirements with your procurement specifications.
