Key Parameters

Substitute Part Grouping Explanation

Substitution for the 77313-127-08 is determined by strict alignment of the following critical parameters:

• Pitch - Mating: 0.100" (2.54mm)
• Number of Positions: 8
• Number of Rows: 2
• Row Spacing - Mating: 0.100" (2.54mm)
• Connector Type: Header, Breakaway
• Contact Type: Male Pin
• Mounting Type: Through Hole
• Termination: Solder
• Fastening Type: Push-Pull
• Shrouding: Unshrouded

The substitute parts listed below meet these core electrical and mechanical requirements. Variations in contact length, insulation height, contact material, and finish specifications are acceptable within the scope of board-to-board or cable connector applications, provided the mating interface dimensions remain compatible.

Parameter Comparison

Engineering Selection Recommendations

77313-127-08LF is the direct equivalent from Amphenol ICC (FCI). This part maintains identical mechanical and electrical specifications to the obsolete 77313-127-08 while offering active product status and RoHS compliance. The LF suffix indicates lead-free termination. This is the primary substitute for direct replacement.

826632-4 from TE Connectivity AMP Connectors is an active alternative with higher current rating (5A versus 3A) and extended operating temperature range (-65°C to 105°C). The AMPMODU Mod II series provides equivalent mating interface compatibility with minor variations in contact geometry and insulation material (PBT versus thermoplastic).

M20-9760446 from Harwin Inc. is an active substitute with cuttable header design and equivalent electrical specifications (3A per contact). The M20 series offers comparable operating temperature range (-40°C to 105°C) and maintains UL94 V-0 flammability rating.

BBD-104-T-B from Samtec Inc. is an active alternative with circular contact geometry and extended operating temperature range (-55°C to 125°C). This part is suitable for applications where contact shape variation is acceptable and higher temperature performance is required.

All substitute parts maintain RoHS3 compliance and MSL 1 rating, supporting modern manufacturing and environmental requirements.

Frequently Asked Questions (FAQ)

Q: Can 77313-127-08LF be used as a direct replacement for 77313-127-08?

A: Yes. The 77313-127-08LF is the direct equivalent with identical mating pitch (0.100"), position count (8), row configuration (2 rows), and connector type (Header, Breakaway). The primary difference is product status (Active versus Obsolete) and RoHS compliance.

Q: What are the key differences between the substitute parts?

A: The primary differences are contact shape (square versus circular in BBD-104-T-B), current rating (3A to 5A), operating temperature range, and insulation material. All maintain the critical 0.100" pitch and 8-position, 2-row configuration required for mating compatibility.

Q: Are all substitute parts compatible with existing PCB footprints?

A: Compatibility depends on specific PCB pad layout and hole sizing. While all parts share the 0.100" (2.54mm) pitch and 2-row configuration, variations in contact length, post diameter, and overall connector height may require footprint verification. The 77313-127-08LF provides the closest mechanical match to the original part.

Q: Which substitute part offers the best environmental compliance?

A: All active substitute parts (77313-127-08LF, 826632-4, BBD-104-T-B, and M20-9760446) are ROHS3 compliant. The 77313-127-08LF and 826632-4 are REACH Affected or Unaffected respectively, depending on regulatory requirements for your application.

Q: What is the difference between breakaway and cuttable header designs?

A: Breakaway headers (77313-127-08, 77313-127-08LF, 826632-4) feature pre-scored sections allowing individual position removal. Cuttable headers (M20-9760446) allow custom position configuration through cutting. Both provide equivalent mating interface performance.

Q: Can BBD-104-T-B be used in applications requiring square contact geometry?

A: No. The BBD-104-T-B features circular contact geometry, which differs from the square contacts in the original part and most other substitutes. Contact shape may affect mating force and connector performance in specific applications.
