Equivalent & Substitute Parts for 77313-127-16LF

Part Overview

The 77313-127-16LF is a rectangular connector header manufactured by Amphenol ICC (FCI) in the BERGSTIK® series. This through-hole vertical header connector features 16 positions arranged in 2 rows with 0.100" (2.54mm) pitch, designed for board-to-board or cable applications. The part is currently active in production with 683 units in stock. Alternative equivalent parts are necessary to address supply chain flexibility, design optimization for specific environmental conditions, or procurement preferences across different manufacturers.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 77313-127-16LF is determined by strict alignment with the following core parameters:

• Connector type classification (Header, Breakaway)
• Contact type (Male Pin)
• Position count (16 positions in 2 rows)
• Mating pitch (0.100" / 2.54mm)
• Row spacing (0.100" / 2.54mm)
• Mounting method (Through Hole)
• Termination method (Solder)
• Fastening mechanism (Push-Pull)

All three substitute parts meet these core electrical and mechanical requirements. Variations in contact length, insulation height, contact material composition, and operating temperature ranges are secondary parameters that may influence selection based on specific application constraints but do not disqualify substitution eligibility.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts are active products with current manufacturing status and meet the core electrical and mechanical specifications of the 77313-127-16LF.

826632-8 (TE Connectivity AMPMODU Mod II): This part is ROHS3 compliant and offers higher current rating (5A versus 3A), making it suitable for applications requiring increased current capacity. Operating temperature range is reduced to -65°C ~ 105°C. Contact material is brass with PBT insulation. Bulk packaging and higher inventory availability (1375 units) support procurement flexibility.

87215-5 (TE Connectivity AMPMODU Mod II): This part maintains the 3A current rating and phosphor bronze contact material consistent with the original specification. Operating temperature range is -65°C ~ 105°C. RoHS status is not applicable. Contact shape is circular rather than square. Bulk packaging with highest inventory availability (1508 units) provides supply chain advantage.

BBD-108-G-A (Samtec BBD Series): This part operates across -55°C ~ 125°C temperature range, providing extended high-temperature capability. ROHS3 compliant. Tube packaging differs from bulk format. Highest inventory availability (1711 units). Insulation height is significantly larger (0.211" versus 0.100"), which may affect board layout compatibility. Current rating is not specified.

Frequently Asked Questions (FAQ)

Q: Can 826632-8 be used as a direct replacement for 77313-127-16LF?

A: Yes. Both parts share identical core specifications: 16-position, 2-row header with 0.100" pitch, through-hole solder termination, and push-pull fastening. The 826632-8 offers higher current rating (5A) and ROHS3 compliance. Operating temperature maximum is reduced from 130°C to 105°C.

Q: What are the physical differences between these substitute parts?

A: Contact length, insulation height, and contact shape vary. The 77313-127-16LF has 0.100" insulation height with square contacts. The 826632-8 has 0.110" insulation height with square contacts. The 87215-5 has 0.090" insulation height with circular contacts. The BBD-108-G-A has 0.211" insulation height with circular contacts. These differences may affect PCB footprint compatibility and mating interface design.

Q: Are there temperature rating differences that affect substitution?

A: Yes. The 77313-127-16LF operates to 130°C maximum. The 826632-8 and 87215-5 are rated to 105°C maximum. The BBD-108-G-A extends to 125°C maximum. Applications requiring operation above 105°C should use either the original part or the BBD-108-G-A.

Q: What is the difference between bulk and tube packaging?

A: Bulk packaging (77313-127-16LF, 826632-8, 87215-5) provides loose components suitable for high-volume assembly. Tube packaging (BBD-108-G-A) provides organized component presentation in reels or tubes, often preferred for automated pick-and-place equipment.

Q: Does contact material affect substitution eligibility?

A: Contact material (phosphor bronze versus brass) is a secondary parameter. Both materials are suitable for the specified 2.54mm pitch header application. Material selection may influence contact resistance and wear characteristics but does not disqualify substitution based on core electrical and mechanical compatibility.

Q: Which substitute part offers the best supply availability?

A: The BBD-108-G-A (Samtec) has the highest inventory at 1711 units, followed by 87215-5 (1508 units) and 826632-8 (1375 units). The original 77313-127-16LF has 683 units available.
