Substitute Part Grouping Explanation

Substitution of the 77313-124-34 is determined by strict equivalence across the following critical parameters:

Connector positioning and pitch: 34 positions in 2 rows at 0.100" (2.54mm) mating pitch and 0.100" row spacing
Contact configuration: Male pin contacts with solder termination
Mounting method: Through-hole mounting on printed circuit boards
Fastening mechanism: Push-pull fastening type
Electrical and mechanical compatibility: Unshrouded header design with board-to-board or cable application capability
Regulatory compliance: UL94 V-0 flammability rating and MSL 1 classification

Substitute parts are grouped into two categories:

Direct Manufacturer Equivalent (Same Manufacturer): 77313-124-34LF from Amphenol ICC maintains identical mechanical and electrical specifications while offering RoHS compliance and active product status.

Cross-Manufacturer Equivalents: Parts from TE Connectivity (1-87215-7, 6-146252-7), 3M (2334-6221TG), Preci-Dip (450-10-234-00-018101, 450-80-234-00-018101, 892-80-034-10-001101, 892-80-034-10-002101), and Samtec (BBD-117-T-A) meet the core 34-position, 2.54mm pitch, through-hole solder header requirements. Variations in contact length, contact finish, insulation material, and operating temperature ranges exist but do not prevent functional substitution when application requirements are within the specified ranges of the substitute part.

Engineering Selection Recommendations

Primary Recommendation for Active Inventory: 77313-124-34LF from Amphenol ICC is the direct equivalent of the obsolete 77313-124-34. This part maintains identical mechanical and electrical specifications while offering RoHS compliance and active product status with 997 units in stock.

Secondary Recommendations for Cross-Manufacturer Substitution:

1-87215-7 (TE Connectivity AMPMODU Mod II) and 6-146252-7 (TE Connectivity AMPMODU Mod II) are functionally equivalent with RoHS compliance and active status. These parts feature extended operating temperature range (-65°C to 105°C) and are suitable for applications requiring broader thermal performance.

450-10-234-00-018101 and 450-80-234-00-018101 (Preci-Dip 450 series) offer ROHS3 compliance and extended operating temperature range (-55°C to 125°C) with 150VDC voltage rating specification. The 450-10 variant features gold mating contact finish, while 450-80 features tin mating contact finish.

892-80-034-10-001101 and 892-80-034-10-002101 (Preci-Dip 892 series) provide ROHS3 compliance with tin contact finish and 150VDC voltage rating. These parts differ in contact length specifications (0.236" vs. 0.276" mating contact length) and overall contact length (0.458" vs. 0.494").

929665-01-17-I (3M 929 series) offers RoHS compliance with gold contact finish and operates across -40°C to 105°C temperature range. Current rating is specified at 2.5A per contact.

BBD-117-T-A (Samtec BBD series) provides ROHS3 compliance with extended operating temperature range (-55°C to 125°C). This part features increased insulation height (0.211") and circular contact geometry.

Compliance Considerations: Applications requiring RoHS compliance should exclude 77313-124-34 (original, non-compliant) and 2334-6221TG (3M, non-compliant). All other substitute parts meet RoHS requirements. REACH compliance varies; parts with REACH Unaffected status (Preci-Dip 450 and 892 series, 929665-01-17-I, BBD-117-T-A) may be preferred for REACH-sensitive applications.

Frequently Asked Questions (FAQ)

Q: Can the 77313-124-34 be directly replaced with 77313-124-34LF?

A: Yes. The 77313-124-34LF is the direct equivalent from the same manufacturer (Amphenol ICC) with identical mechanical and electrical specifications. The primary difference is that 77313-124-34LF is RoHS compliant and maintains active product status, whereas the original 77313-124-34 is obsolete and RoHS non-compliant.

Q: What are the critical parameters that determine if a substitute part is compatible?

A: Compatibility is determined by: 34 positions in 2 rows, 0.100" (2.54mm) mating pitch, 0.100" row spacing, male pin contacts, through-hole solder termination, push-pull fastening, and unshrouded design. All listed substitute parts meet these core requirements.

Q: Do variations in contact length affect substitution?

A: Contact length variations exist among substitute parts (ranging from 0.125" to 0.318" mating contact length). These variations do not prevent functional substitution provided the application's mechanical envelope and mating connector specifications accommodate the substitute part's dimensions. PCB layout and connector cavity depth must be verified against the specific substitute part's contact length.

Q: Are there differences in operating temperature ranges among substitute parts?

A: Yes. Operating temperature ranges vary: 77313-124-34LF operates -65°C to 130°C, TE Connectivity parts operate -65°C to 105°C, 3M 2334-6221TG operates -55°C to 105°C, Preci-Dip 450 and 892 series operate -55°C to 125°C, 3M 929665-01-17-I operates -40°C to 105°C, and Samtec BBD-117-T-A operates -55°C to 125°C. Application thermal requirements must be matched to the substitute part's specified range.

Q: What is the difference between parts with gold and tin contact finishes?

A: Contact finish affects corrosion resistance and mating force characteristics. Gold-finished contacts (77313-124-34LF, 1-87215-7, 2334-6221TG, 450-10-234-00-018101, 6-146252-7, 929665-01-17-I) provide superior corrosion resistance. Tin-finished contacts (450-80-234-00-018101, 892-80-034-10-001101, 892-80-034-10-002101, BBD-117-T-A) are cost-effective alternatives suitable for standard industrial environments. Selection depends on application environment and reliability requirements.

Q: How do insulation material differences impact part selection?

A: Insulation materials vary among substitutes: thermoplastic (77313-124-34, 77313-124-34LF, 1-87215-7), glass-filled thermoplastic (2334-6221TG), glass-filled PCT/polyester (Preci-Dip 450 series), glass-filled polyamide/nylon (Preci-Dip 892 series), liquid crystal polymer (6-146252-7), glass-filled PBT/polyester (929665-01-17-I), and glass-filled polyester (BBD-117-T-A). Material selection affects mechanical strength, thermal stability, and chemical resistance. Applications requiring enhanced mechanical or thermal properties should specify glass-filled or LCP variants.

Q: What packaging options are available?

A: Packaging varies by part: 77313-124-34LF is supplied in bulk, Preci-Dip 450 and 892 series are supplied in bulk, TE Connectivity parts are supplied in bulk, 3M 2334-6221TG packaging is not specified, 3M 929665-01-17-I is supplied in bulk, and Samtec BBD-117-T-A is supplied in tube. Packaging selection affects handling, storage, and assembly processes.

Q: Are there current rating differences among substitute parts?

A: Yes. Current ratings are specified as: 3A per contact (77313-124-34LF, 1-87215-7, 2334-6221TG, 450-10-234-00-018101, 450-80-234-00-018101, 892-80-034-10-001101, 892-80-034-10-002101, 6-146252-7), 2.5A (929665-01-17-I), and not specified (77313-124-34, BBD-117-T-A). Applications with current requirements exceeding 2.5A per contact should exclude 929665-01-17-I.

Q: Which substitute parts offer the widest operating temperature range?

A: The 77313-124-34LF offers the widest operating temperature range at -65°C to 130°C. For applications requiring extended low-temperature performance, this part is preferred. For applications requiring extended high-temperature performance, Preci-Dip 450 and 892 series and Samtec BBD-117-T-A offer -55°C to 125°C range.
