Amphenol ICC 77312-876LF Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 77312-876LF is an active rectangular connector header designed for through-hole board-to-board applications. This BERGSTIK® series component features a 5-position, single-row configuration with 0.100" (2.54mm) pitch spacing and is rated for 3A per contact. The connector employs gold-plated phosphor bronze contacts with tin-plated posts, operating across -65°C to 125°C. With 655 units in stock and RoHS compliance, this part serves as a standard interconnect solution for embedded systems and industrial electronics. Equivalent and substitute parts are identified to provide design flexibility, supply chain alternatives, and compatibility options for applications requiring identical or functionally equivalent rectangular connector headers.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 77312-876LF is determined by the following critical parameters:

Primary Matching Criteria:

• Connector Type: Header (male pin contact)
• Pitch - Mating: 0.100" (2.54mm)
• Number of Positions: 5
• Number of Rows: 1
• Mounting Type: Through Hole
• Termination: Solder
• Style: Board to Board

Secondary Compatibility Factors:

• Contact Shape (Square or Circular acceptable)
• Contact Material (Phosphor Bronze or Brass Alloy acceptable)
• Insulation Material (Thermoplastic, PCT, or LCP acceptable)
• RoHS Compliance Status (RoHS Compliant or ROHS3 Compliant)
• Operating Temperature Range (must support application requirements)

The three identified substitute parts—Mill-Max 800-10-005-10-001000, Mill-Max 800-10-005-10-002000, and Samtec HTSW-105-07-G-S—satisfy all primary matching criteria and maintain functional equivalence for standard board-to-board interconnect applications.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts maintain active product status and comply with RoHS or ROHS3 regulations, ensuring regulatory alignment with the original 77312-876LF component.

Mill-Max 800-10-005-10-001000: This substitute features circular contacts with brass alloy material and PCT insulation. The overall contact length of 0.438" (11.12mm) provides extended mating engagement compared to the original part. All positions are loaded, and the part carries ROHS3 compliance with REACH unaffected status.

Mill-Max 800-10-005-10-002000: This variant shares the same material composition and compliance profile as the 800-10-005-10-001000 but with a reduced overall contact length of 0.385" (9.77mm). This configuration offers a more compact profile while maintaining full position loading and identical electrical characteristics.

Samtec HTSW-105-07-G-S: This substitute retains square contact geometry and phosphor bronze material matching the original part, with LCP insulation providing enhanced thermal stability. The operating temperature range of -55°C to 125°C covers standard industrial applications. All positions are loaded, and the part supports both board-to-board and cable applications. ROHS3 compliance and REACH unaffected status are confirmed.

Selection between substitutes depends on mechanical envelope constraints, contact engagement depth requirements, and application-specific temperature extremes. All parts share identical pitch, position count, and solder termination compatibility with the original design.

Frequently Asked Questions (FAQ)

Q: Can the Mill-Max 800-10-005-10-001000 and 800-10-005-10-002000 be used interchangeably with the 77312-876LF?

A: Both Mill-Max parts are functionally equivalent for standard board-to-board interconnect applications. The primary difference is overall contact length: 0.438" (11.12mm) for the 001000 variant and 0.385" (9.77mm) for the 002000 variant. Selection depends on PCB thickness and mating depth requirements. Both feature circular contacts versus the square contacts of the original part, which does not affect electrical performance but may impact mechanical fit in constrained applications.

Q: What is the difference between the Samtec HTSW-105-07-G-S and the original 77312-876LF?

A: The Samtec part shares square contact geometry and phosphor bronze material with the original. Key differences include LCP insulation (versus thermoplastic), natural insulation color (versus black), and a slightly lower operating temperature minimum of -55°C (versus -65°C). The Samtec part supports both board-to-board and cable applications, providing additional design flexibility. All other electrical and mechanical parameters align with the original specification.

Q: Are all substitute parts RoHS compliant?

A: Yes. The original 77312-876LF carries RoHS Compliant status. All three substitute parts carry ROHS3 Compliant status, which represents an updated regulatory framework and maintains full compliance with RoHS requirements. Both compliance levels are acceptable for applications requiring RoHS certification.

Q: What is the significance of "Number of Positions Loaded" in the specification?

A: The original 77312-876LF lists 3 positions loaded out of 5 total positions, indicating that only 3 contact positions are populated in the standard configuration. All three substitute parts list all positions loaded, meaning all 5 contact positions are populated. This difference does not affect substitution eligibility for applications requiring a 5-position header but may require design verification if the original application relied on the unpopulated positions for mechanical or electrical purposes.

Q: Can these parts be used in high-temperature applications?

A: The original 77312-876LF operates from -65°C to 125°C. The Samtec HTSW-105-07-G-S operates from -55°C to 125°C, which covers standard industrial temperature ranges. The Mill-Max parts do not specify operating temperature limits in the provided data. For applications requiring operation below -55°C, the original 77312-876LF is the specified choice. For standard industrial applications within -55°C to 125°C, all parts are suitable.

Q: What packaging differences exist between these parts?

A: The original 77312-876LF is supplied in Bag packaging. The Mill-Max 800-10-005-10-001000 and 800-10-005-10-002000 are supplied in Bulk packaging. The Samtec HTSW-105-07-G-S is supplied in Bag packaging. Packaging format does not affect electrical or mechanical compatibility but may influence inventory management and handling procedures.
