Substitute Part Grouping Explanation

Substitution for the 77313-124-16 is determined by the following critical parameters that must remain constant:

Pitch - Mating: 0.100" (2.54mm)
Number of Positions: 16
Number of Rows: 2
Row Spacing - Mating: 0.100" (2.54mm)
Mounting Type: Through Hole
Connector Type: Header
Contact Type: Male Pin
Termination: Solder
Fastening Type: Push-Pull
Shrouding: Unshrouded
Style: Board to Board or Cable

Substitute parts are grouped into two categories:

Category 1: Direct Amphenol ICC Substitutes - Parts from the same manufacturer with identical electrical and mechanical specifications but updated product status and compliance certifications.

Category 2: Cross-Manufacturer Substitutes - Parts from alternative manufacturers (Preci-Dip, TE Connectivity, Samtec) that maintain the same pitch, position count, row configuration, and mounting method. These parts may have variations in contact geometry, material composition, and finish specifications while preserving functional compatibility.

Engineering Selection Recommendations

Primary Recommendation: 77313-124-16LF

The 77313-124-16LF is the direct successor to the 77313-124-16 from Amphenol ICC. This part maintains identical electrical and mechanical specifications while offering active product status and RoHS compliance. The LF designation indicates lead-free termination, aligning with current manufacturing standards. This is the preferred choice for new designs and ongoing procurement.

Secondary Recommendations for Active Designs:

For applications requiring RoHS3 compliance and active product status, the following cross-manufacturer substitutes are qualified:

450-10-216-00-018101 (Preci-Dip): Maintains 16-position, 2.54mm pitch configuration with gold-plated contacts. Offers 3A current rating and 150VDC voltage rating. ROHS3 compliant.
450-80-216-00-018101 (Preci-Dip): Identical to 450-10-216-00-018101 with tin-plated mating contacts instead of gold. ROHS3 compliant.
451-10-216-00-003101 (Preci-Dip): Preci-Dip 451 series alternative with gold-plated contacts. ROHS3 compliant.
826632-8 (TE Connectivity): AMPMODU Mod II series header with 16 positions at 2.54mm pitch. Offers 5A current rating. ROHS3 compliant.

Frequently Asked Questions (FAQ)

Q: Can the 77313-124-16LF be used as a direct replacement for the 77313-124-16?

A: Yes. The 77313-124-16LF is the direct successor from Amphenol ICC with identical pitch, position count, row spacing, and mounting configuration. The primary differences are active product status and RoHS compliance.

Q: What are the key differences between Preci-Dip 450 and 451 series substitutes?

A: Both series maintain the required 16-position, 2.54mm pitch configuration. The 450 series features contact lengths of 0.169" (4.30mm) mating and 0.124" (3.15mm) post. The 451 series has shorter mating contacts at 0.118" (3.00mm) and slightly longer post contacts at 0.126" (3.20mm). Both are ROHS3 compliant with 3A current rating and 150VDC voltage rating.

Q: Are there differences in contact geometry between the original part and cross-manufacturer substitutes?

A: Yes. The original 77313-124-16 features square contacts, while several substitutes (Preci-Dip 450, 451 series and Samtec BBD series) use circular contacts. Square contacts provide different mating force and contact pressure characteristics compared to circular contacts. Verify mechanical compatibility with mating connectors before substitution.

Q: What is the significance of the LF designation in 77313-124-16LF?

A: LF indicates lead-free termination, compliant with RoHS directives. This eliminates lead from the solder termination while maintaining electrical and mechanical performance.

Q: Which substitutes offer the highest current rating?

A: The TE Connectivity 826632-8 offers 5A per contact, compared to 3A for most other substitutes. Verify current requirements for your application before selection.

Q: Are there voltage rating differences among the substitutes?

A: The original 77313-124-16 does not specify a voltage rating. Preci-Dip substitutes (450, 451, 892 series) specify 150VDC. TE Connectivity and Samtec parts do not provide voltage ratings in the available specifications. Consult manufacturer datasheets for complete electrical ratings.

Q: What packaging options are available for these substitutes?

A: Packaging varies by manufacturer. Amphenol ICC 77313-124-16LF is available in bulk. Preci-Dip and TE Connectivity substitutes are supplied in bulk. Samtec BBD series is supplied in tube packaging. Verify packaging requirements for your procurement and assembly processes.

Q: Can I substitute a part with different contact finish without affecting performance?

A: Contact finish affects corrosion resistance and mating force characteristics. Gold-plated contacts (77313-124-16, 77313-124-16LF, 450-10, 451-10, 826632-8, 87215-5, 892-70, BBD-108-G-A) provide superior corrosion resistance compared to tin-plated alternatives (450-80, BBD-108-T-A). For applications in corrosive environments or requiring long-term reliability, gold-plated contacts are preferred.

Q: What is the operating temperature range for these connectors?

A: The original 77313-124-16 does not specify operating temperature. The 77313-124-16LF operates from -65°C to 130°C. Preci-Dip substitutes operate from -55°C to 125°C. TE Connectivity parts operate from -65°C to 105°C. Verify temperature requirements for your application.
