Key Parameters

Substitute Part Grouping Explanation

Substitution for the 71991-313 is determined by strict alignment of the following critical parameters:

Primary Substitution Criteria:

• Connector type (Receptacle, Bottom or Top Entry)
• Contact type (Female Socket)
• Number of positions (26)
• Pitch - mating (0.100" / 2.54mm)
• Number of rows (2)
• Row spacing - mating (0.100" / 2.54mm)
• Mounting type (Through Hole)
• Termination method (Solder)
• Fastening type (Push-Pull)
• Style (Board to Board)

Identified Substitute:

The TE Connectivity AMP Connectors part number 534267-6 meets all primary substitution criteria. This part is a 26-position receptacle connector with identical pitch, row configuration, mounting type, and termination method. The 534267-6 is classified as active product status, providing ongoing availability and support.

Non-Qualifying Substitute:

The Amphenol ICC part number 75867-106LF does not qualify as a direct substitute. While it shares the same pitch (0.100" / 2.54mm) and mounting type (Through Hole), it differs in critical parameters: it is a header connector (male pin contact type) with 34 positions in a board-to-cable/wire configuration, making it functionally incompatible with the 71991-313 receptacle application.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement:

The TE Connectivity 534267-6 is the qualified direct substitute for the obsolete Amphenol ICC 71991-313. Both parts share identical connector type, contact configuration, position count, pitch, row spacing, mounting method, and fastening mechanism. The 534267-6 maintains active product status, ensuring continued availability and manufacturing support.

Compliance Consideration:

The 534267-6 is classified as RoHS non-compliant. If RoHS compliance is required for your application, this substitution may not be suitable without additional regulatory review. The original 71991-313 RoHS status is not specified in the provided data.

Material Difference:

The 534267-6 uses polyester glass-filled insulation material, compared to the thermoplastic glass-filled insulation of the 71991-313. Both materials meet UL94 V-0 flammability requirements where specified. Verify that this material change is acceptable for your thermal and mechanical environment.

Contact Finish Thickness:

The 534267-6 post contact finish thickness is 150.0µin (3.81µm), compared to 78.7µin (2.00µm) on the 71991-313. This increased thickness provides enhanced durability for repeated mating cycles.

Frequently Asked Questions (FAQ)

Q: Can the 75867-106LF be used as a substitute for the 71991-313?

A: No. The 75867-106LF is a header connector with male pin contacts designed for board-to-cable/wire applications. The 71991-313 is a receptacle with female socket contacts for board-to-board connections. These are functionally incompatible connector types and cannot be interchanged.

Q: What makes the 534267-6 a direct substitute?

A: The 534267-6 matches all critical substitution parameters: 26-position receptacle with female sockets, 0.100" (2.54mm) pitch, 2-row configuration with 0.100" row spacing, through-hole solder termination, push-pull fastening, and board-to-board style. These parameters define the mechanical and electrical interface compatibility.

Q: Is the 534267-6 available in the same packaging as the 71991-313?

A: The 534267-6 is supplied in tube packaging. The original 71991-313 packaging specification is not provided in the available data. Verify packaging requirements for your procurement and assembly processes.

Q: Does the insulation material change from thermoplastic to polyester affect performance?

A: Both materials are glass-filled and meet UL94 V-0 flammability standards. The polyester material in the 534267-6 may have different thermal and mechanical properties. Evaluate compatibility with your specific operating temperature range and mechanical stress conditions.

Q: What is the significance of the increased contact finish thickness on the 534267-6?

A: The 534267-6 post contact finish is 150.0µin (3.81µm) compared to 78.7µin (2.00µm) on the 71991-313. Thicker plating generally provides improved wear resistance and contact reliability over extended mating cycles.

Q: Are there RoHS compliance implications with the 534267-6?

A: The 534267-6 is RoHS non-compliant. If your application or market requires RoHS compliance, this substitution requires regulatory review and approval before implementation.
