Amphenol ICC 77313-124-64 Rectangular Connector Header - Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 77313-124-64 is a vertical rectangular connector header with 64 positions at 2.54mm pitch, designed for through-hole board-to-board or cable applications. This part is classified as obsolete, making identification of active equivalent and substitute components essential for ongoing design support and procurement continuity. Active alternatives maintain the core electrical and mechanical specifications while offering improved availability and compliance status.

Key Parameters

Substitute Part Grouping Explanation

Substitution logic for the 77313-124-64 is based on the following critical parameters that must align for functional equivalence:

• Pitch - Mating: 0.100" (2.54mm)
• Number of Positions: 64
• Number of Rows: 2
• Row Spacing - Mating: 0.100" (2.54mm)
• Contact Type: Male Pin
• Mounting Type: Through Hole
• Termination: Solder
• Connector Style: Board to Board or Cable

The substitute parts are categorized as follows:

Direct Amphenol ICC Equivalent (77313-124-64LF): Maintains identical electrical and mechanical specifications with active product status and improved compliance certifications.

Cross-Manufacturer Alternative (BBD-132-T-B by Samtec Inc.): Provides equivalent 64-position, 2.54mm pitch through-hole header functionality with active status, though with variations in contact geometry and insulation material specifications.

Note on 95278-101A14LF: This part is listed in the original substitute field but differs fundamentally in position count (14 vs. 64) and mounting technology (surface mount vs. through hole), making it unsuitable as a direct substitute for the 77313-124-64.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Preferred): The 77313-124-64LF is the primary substitute for the obsolete 77313-124-64. Both parts are from Amphenol ICC and maintain identical electrical and mechanical specifications. The 77313-124-64LF offers active product status, RoHS compliance, and documented operating temperature and current ratings, making it the optimal choice for new designs and ongoing production support.

For Cross-Manufacturer Substitution: The Samtec BBD-132-T-B provides equivalent 64-position, 2.54mm pitch through-hole header functionality with active status and ROHS3 compliance. However, this part exhibits dimensional variations in contact length, insulation height, contact shape (circular vs. square), and contact finish material (tin vs. gold). These differences may affect mating force characteristics, contact resistance, and mechanical fit within existing connector housings. Cross-manufacturer substitution requires mechanical and electrical validation in the target application.

Compliance Considerations: The original 77313-124-64 is RoHS non-compliant. Both substitute parts (77313-124-64LF and BBD-132-T-B) meet current RoHS requirements, supporting compliance with modern procurement and environmental regulations.

Frequently Asked Questions (FAQ)

Q: Can the 77313-124-64LF be used as a direct replacement for the 77313-124-64?

A: Yes. The 77313-124-64LF maintains identical pitch (2.54mm), position count (64), row configuration (2 rows), contact type (male pin), mounting method (through hole), and termination (solder). The primary differences are product status (active vs. obsolete), RoHS compliance, and documented operating temperature and current ratings.

Q: What are the key differences between the 77313-124-64LF and BBD-132-T-B?

A: Both parts share the same pitch, position count, and row configuration. Key differences include: contact length (77313-124-64LF: 0.266" mating / 0.114" post; BBD-132-T-B: 0.125" both), insulation height (77313-124-64LF: 0.100"; BBD-132-T-B: 0.335"), contact shape (77313-124-64LF: square; BBD-132-T-B: circular), contact finish (77313-124-64LF: gold; BBD-132-T-B: tin), and insulation material (77313-124-64LF: thermoplastic; BBD-132-T-B: polyester, glass filled).

Q: Is the 95278-101A14LF a suitable substitute?

A: No. The 95278-101A14LF is a 14-position surface-mount header, fundamentally different from the 77313-124-64 (64-position through-hole). Position count and mounting technology are non-negotiable substitution parameters.

Q: What packaging options are available for the substitute parts?

A: The 77313-124-64LF is supplied in bulk packaging. The BBD-132-T-B is supplied in tube packaging. Packaging selection depends on procurement volume and assembly process requirements.

Q: Are there operating temperature or current rating differences I should consider?

A: The 77313-124-64LF is rated for -65°C to 130°C with 3A per contact. The BBD-132-T-B is rated for -55°C to 125°C with unspecified current rating. The original 77313-124-64 does not specify these parameters. Application requirements should drive selection between these alternatives.
