Amphenol ICC 77313-102-12 Rectangular Connector Header - Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 77313-102-12 is a vertical rectangular connector header featuring 12 positions arranged in 2 rows with 0.100" (2.54mm) pitch spacing. This through-hole solder-terminated component is designed for board-to-board or cable interconnection applications. The part carries an obsolete product status, making equivalent and substitute parts necessary for ongoing design support and procurement continuity. Active alternatives from multiple manufacturers provide functionally compatible solutions with enhanced compliance profiles and extended availability.

Substitute Part Grouping Explanation

Substitution eligibility for the 77313-102-12 is determined by strict alignment with the following core parameters: 12-position, 2-row configuration; 0.100" (2.54mm) mating pitch and row spacing; male pin contact type; through-hole solder termination; push-pull fastening; square contact geometry; and UL94 V-0 flammability rating. Substitute parts must maintain these electrical and mechanical specifications to ensure direct compatibility without design modification.

Variations in contact length (mating and post), insulation height, contact material composition, insulation material type, and contact finish specifications are permitted within the substitute group, as these parameters do not affect connector mating compatibility or board-level integration. Operating temperature range, current rating, and RoHS compliance status represent secondary selection criteria that may influence application suitability but do not preclude functional substitution.

Engineering Selection Recommendations

Direct Amphenol ICC Replacement: The 77313-102-12LF represents the active-status equivalent from the original manufacturer. This part maintains identical mechanical and electrical specifications while offering RoHS compliance and an extended operating temperature range of -65°C to 130°C. Selection of this part eliminates supplier transition risk and maintains design continuity within the Amphenol ICC BERGSTIK® series.

Multi-Manufacturer Alternatives: The TE Connectivity 5-146257-6 (AMPMODU Mod II series) and Sullins PBC06DAAN provide RoHS-compliant alternatives with active product status and extended temperature ratings. These parts are suitable for applications requiring regulatory compliance and long-term availability assurance.

Legacy Compliance Considerations: The 3M 2312-6121-TG and 2312-6121TB parts maintain non-compliant RoHS status, consistent with the original 77313-102-12. These options are appropriate for retrofit applications or legacy system support where RoHS compliance is not mandated.

Contact Length Variants: Sullins PBC06DABN, PBC06DACN, PBC06DADN, and PBC06DAEN offer extended post lengths (0.230", 0.320", 0.420", and 0.520" respectively) for applications requiring deeper board penetration or specific PCB stackup configurations. These variants maintain all core connector specifications while accommodating varied mechanical integration requirements.

Frequently Asked Questions (FAQ)

Q: Can the 77313-102-12LF be used as a direct replacement for the obsolete 77313-102-12?

A: Yes. The 77313-102-12LF maintains identical mating pitch, row spacing, position count, contact geometry, and termination method. The primary differences are active product status, RoHS compliance, and extended operating temperature range (-65°C to 130°C versus unspecified for the original). No design modification is required.

Q: What distinguishes the Sullins PBC06DA series variants from one another?

A: All Sullins PBC06DA variants share identical mating specifications (12 positions, 2 rows, 0.100" pitch) and contact geometry. The variants differ only in contact post length: PBC06DAAN (0.120"), PBC06DABN (0.230"), PBC06DACN (0.320"), PBC06DADN (0.420"), and PBC06DAEN (0.520"). Selection depends on required board penetration depth and PCB thickness accommodation.

Q: Are there compliance differences between substitute options?

A: Yes. The 77313-102-12LF, 0010897122, 5-146257-6, and all Sullins PBC06DA variants are RoHS compliant. The 3M 2312-6121-TG and 2312-6121TB are RoHS non-compliant. Application regulatory requirements determine appropriate selection.

Q: Do contact material differences affect connector performance?

A: Contact material composition (phosphor bronze versus copper alloy) and finish specifications (gold thickness, tin versus tin-lead post finish) are provided for reference but do not affect mating compatibility or basic electrical function within the specified current and voltage operating envelope. Material selection influences long-term reliability characteristics and environmental resistance.

Q: What is the significance of the contact finish thickness variations?

A: Contact finish thickness (mating surface gold plating and post tin plating) affects durability under repeated mating cycles and environmental exposure. Thicker finishes generally provide extended service life. All listed parts meet UL94 V-0 flammability requirements regardless of finish thickness variation.

Q: Can insulation material differences impact board-level integration?

A: Insulation material type (thermoplastic, thermoplastic glass-filled, liquid crystal polymer, or polybutylene terephthalate) affects mechanical rigidity and thermal stability but does not alter connector pitch, position count, or mating interface geometry. Material selection influences mechanical robustness and temperature performance but not compatibility.

Q: Is the Molex 0010897122 mechanically compatible with the original 77313-102-12?

A: Yes. The Molex part maintains the required 12-position, 2-row configuration with 0.100" mating pitch and row spacing. Minor variations in insulation height (0.090" versus 0.100") and contact length do not prevent successful mating or board integration.
