76341-318 Equivalent & Substitute Parts

Part Overview

The 76341-318 is an 18-position receptacle connector manufactured by Amphenol ICC (FCI) in the Dubox™ series. This board-to-board rectangular connector features 0.100" (2.54mm) pitch through-hole mounting with gold-plated mating contacts and tin-plated posts. The part is currently obsolete, making identification of suitable substitutes essential for ongoing system support and new design implementations.

Substitute Part Grouping Explanation

Substitution eligibility for the 76341-318 is determined by strict alignment across the following critical parameters:

Connector Type & Contact Configuration: Receptacle with female socket contacts
Position Count & Pitch: 18 positions at 0.100" (2.54mm) mating pitch
Mounting & Termination: Through-hole solder termination with push-pull fastening
Contact Finish: Gold mating surface with tin post finish
Insulation Material & Flammability: Glass-filled thermoplastic rated UL94 V-0

The identified substitutes maintain these core electrical and mechanical parameters, ensuring functional compatibility in board-to-board applications. Variations in secondary attributes such as packaging format, product status, and compliance certifications are noted but do not affect interchangeability at the connector interface level.

Engineering Selection Recommendations

76341-318LF is the primary direct substitute. This part maintains identical mechanical and electrical specifications within the same Dubox™ series while offering active product status and RoHS compliance. The transition from obsolete to active status ensures long-term availability and supply chain stability. Packaging is supplied in tube format.

1-215297-8 serves as a cross-manufacturer alternative from TE Connectivity's AMPMODU HV-100 series. This part satisfies all core substitution criteria with equivalent connector interface parameters. Differences include kinked pin termination option, slightly increased contact post length (0.122" vs. 0.114"), and polyester-based insulation material. RoHS compliance and active product status support ongoing procurement. Packaging is supplied in bulk format.

Both substitutes maintain UL94 V-0 flammability rating, MSL 1 moisture sensitivity, and identical pitch and position configuration, ensuring mechanical and electrical compatibility in board-to-board applications.

Frequently Asked Questions (FAQ)

Q: Can 76341-318LF be used as a direct replacement for 76341-318?

A: Yes. The 76341-318LF maintains identical electrical and mechanical specifications including 18-position configuration, 0.100" pitch, gold mating contacts, tin post finish, and push-pull fastening. The primary difference is product status (active vs. obsolete) and RoHS compliance. Packaging format differs (tube vs. original specification).

Q: What are the key differences between 76341-318LF and 1-215297-8?

A: Both parts share the same 18-position, 0.100" pitch receptacle configuration with gold/tin contact finish and push-pull fastening. Differences include manufacturer (Amphenol ICC vs. TE Connectivity), series designation (Dubox™ vs. AMPMODU HV-100), contact post length (0.114" vs. 0.122"), insulation material (thermoplastic vs. polyester), and termination options (solder vs. kinked pin/solder).

Q: Are there any compatibility concerns when substituting these parts?

A: Substitution is mechanically and electrically compatible at the connector interface. The 0.100" pitch, 18-position configuration, and contact finish specifications ensure mating compatibility with corresponding plug connectors. Verify PCB layout accommodates any dimensional variations, particularly the contact post length difference in the TE Connectivity part (0.122" vs. 0.114").

Q: What is the significance of RoHS compliance for these parts?

A: The original 76341-318 is RoHS non-compliant. Both substitutes (76341-318LF and 1-215297-8) are RoHS compliant, meeting environmental and regulatory requirements for new designs and applications subject to RoHS directives.

Q: How do packaging differences affect part selection?

A: 76341-318LF is supplied in tube packaging, while 1-215297-8 is supplied in bulk packaging. Packaging format does not affect connector functionality but may influence procurement logistics, handling procedures, and inventory management practices.
