Substitute Part Grouping Explanation

Substitution eligibility is determined by strict alignment with the following core parameters: connector type (header), contact type (male pin), number of positions (6), number of rows (2), pitch (2.54mm), mounting type (through hole), termination method (solder), and fastening type (push-pull). All substitute parts listed maintain these fundamental electrical and mechanical specifications, ensuring direct functional compatibility at the board interface level.

Substitute parts are grouped into two categories:

Category 1: Direct Amphenol ICC Equivalents - Parts sharing identical series designation (BERGSTIK®) and manufacturer, differing only in RoHS compliance status and packaging.

Category 2: Cross-Manufacturer Alternatives - Parts from 3M, TE Connectivity, Würth Elektronik, and Mill-Max Manufacturing that meet core dimensional and electrical requirements while offering active product status and improved compliance certifications.

Engineering Selection Recommendations

Primary Recommendation: 77313-122-06LF (Amphenol ICC)

This part represents the direct active equivalent to the obsolete 77313-122-06, maintaining identical electrical and mechanical specifications within the BERGSTIK® series. The LF designation indicates RoHS compliance, addressing regulatory requirements while preserving all functional characteristics. This selection eliminates design re-qualification and provides the highest compatibility assurance.

Secondary Recommendation: 61300621121 (Würth Elektronik WR-PHD)

This part meets core substitution criteria with matching 6-position, 2.54mm pitch configuration and phosphor bronze contact material. It carries ROHS3 compliance and active product status. The WR-PHD series offers robust availability and established supply chain presence.

Alternative Recommendation: 826632-3 (TE Connectivity AMPMODU Mod II)

This part provides active product status with ROHS3 compliance and UL94 V-0 flammability rating. The AMPMODU Mod II series maintains 6-position, 2.54mm pitch specifications with gold-plated mating contacts. Higher current rating (5A) and improved contact finish thickness provide enhanced performance margins.

Functional Alternative: 818-22-006-10-005101, 818-22-006-10-006101, 818-22-006-10-007101 (Mill-Max)

These piston-type connectors maintain 6-position, 2.54mm pitch configuration with gold-plated copper alloy contacts. The piston contact design differs from the male pin design of the original part, requiring board layout verification. These parts offer ROHS3 compliance and active status. Selection depends on mechanical compatibility with existing mating receptacles.

Frequently Asked Questions (FAQ)

Q: Can 77313-122-06LF be used as a direct replacement for 77313-122-06?

A: Yes. The 77313-122-06LF is the active equivalent within the same BERGSTIK® series, maintaining identical electrical and mechanical specifications. The LF suffix indicates RoHS lead-free compliance. No design changes are required.

Q: What is the primary difference between header and piston connector types?

A: Header connectors feature male pins that insert into mating receptacles. Piston connectors use spring-loaded contacts that compress when mated. Both achieve 6-position, 2.54mm pitch connectivity, but piston designs require compatible receptacle geometry. Verify mating receptacle specifications before selecting piston alternatives.

Q: Are all listed substitutes mechanically compatible with existing PCB footprints?

A: All listed parts maintain 6-position, 2.54mm pitch and through-hole mounting, ensuring PCB footprint compatibility. However, contact length and overall connector height vary across manufacturers. Verify mating receptacle engagement depth and connector stack height against design specifications before final selection.

Q: Which substitute offers the best RoHS compliance status?

A: Parts 77313-122-06LF, 5-87543-3, 61300621121, 818-22-006-10-005101, 818-22-006-10-006101, 818-22-006-10-007101, and 826632-3 all carry RoHS or ROHS3 compliance. The 77313-122-06LF provides direct series equivalence with compliance. Würth Elektronik 61300621121 and TE Connectivity 826632-3 offer ROHS3 compliance with active product status.
