Amphenol ICC 71991-315 Rectangular Connector - Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 71991-315 is a 30-position receptacle connector with 0.100" (2.54mm) pitch, designed for board-to-board applications using through-hole solder termination. This connector features gold-plated mating contacts and is part of the Dubox™ series. The part is currently listed as obsolete, making identification of equivalent and substitute components essential for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the 71991-315 is determined by strict alignment of the following critical parameters:

• Connector type (Receptacle, Bottom or Top Entry)
• Contact type (Female Socket)
• Number of positions (30)
• Pitch and row spacing (0.100" / 2.54mm)
• Mounting method (Through Hole)
• Termination type (Solder)
• Fastening mechanism (Push-Pull)
• Contact finish (Gold mating surface)

The substitute parts are grouped into two categories:

Direct Amphenol ICC Substitutes: Parts that maintain identical electrical and mechanical specifications within the same manufacturer ecosystem.

Cross-Manufacturer Equivalent: Parts from alternative manufacturers that satisfy all critical substitution parameters while maintaining functional compatibility.

Parameter Comparison

Engineering Selection Recommendations

71991-315LF (Amphenol ICC - Direct Substitute)

The 71991-315LF is the primary substitute for the obsolete 71991-315. Both parts share identical electrical and mechanical specifications within the Dubox™ series. The 71991-315LF maintains active product status and is RoHS compliant, making it suitable for new designs and legacy system replacements. Packaging is supplied in tube format with 2801 units in current inventory.

1-534267-2 (TE Connectivity - Cross-Manufacturer Equivalent)

The TE Connectivity 1-534267-2 from the AMPMODU Mod IV series provides functional equivalence with identical position count, pitch, and board-to-board configuration. This part is active and maintains the same contact material and gold mating finish. The insulation material differs (polyester versus thermoplastic glass-filled), and the part is RoHS non-compliant. This option is suitable for applications where cross-manufacturer compatibility is acceptable and RoHS compliance is not required.

75867-107LF (Amphenol ICC - Limited Compatibility)

The 75867-107LF is a header connector from the Quickie™ series with 40 positions and right-angle mounting. While it shares the same pitch, row spacing, and through-hole solder termination, the increased position count (40 versus 30), header connector type (male pin versus female socket receptacle), and board-to-cable/wire style (versus board-to-board) make this part unsuitable as a direct substitute. This connector is listed for reference only and does not meet substitution criteria for the 71991-315.

Frequently Asked Questions (FAQ)

Q: Can the 71991-315LF directly replace the obsolete 71991-315 in existing designs?

A: Yes. The 71991-315LF maintains identical electrical and mechanical specifications as the 71991-315 within the Dubox™ series. Both are 30-position receptacles with 0.100" pitch, through-hole solder termination, and push-pull fastening. The primary difference is product status (active versus obsolete) and RoHS compliance certification on the LF variant.

Q: What are the key differences between the Amphenol ICC 71991-315LF and the TE Connectivity 1-534267-2?

A: Both parts are 30-position receptacles with identical pitch and row spacing. The primary differences are manufacturer (Amphenol ICC versus TE Connectivity), series designation (Dubox™ versus AMPMODU Mod IV), insulation material composition (thermoplastic glass-filled versus polyester glass-filled), and RoHS compliance status (compliant versus non-compliant). Electrical and mechanical compatibility is maintained.

Q: Why is the 75867-107LF listed as a substitute if it has 40 positions instead of 30?

A: The 75867-107LF does not qualify as a substitute for the 71991-315. It is included in the reference data but fails critical substitution criteria: it is a header connector (male pin) rather than a receptacle (female socket), has 40 positions instead of 30, and is configured for board-to-cable/wire applications rather than board-to-board. This part is not compatible with the 71991-315 application requirements.

Q: What packaging options are available for substitute parts?

A: The 71991-315LF is supplied in tube packaging. The 1-534267-2 is also supplied in tube packaging. Packaging format should be verified with the component supplier based on assembly requirements and quantity needs.

Q: Are there any compliance or certification differences between the substitute parts?

A: The 71991-315LF is RoHS compliant and REACH affected. The 1-534267-2 is RoHS non-compliant but REACH affected. Both parts carry UL94 V-0 or equivalent flammability ratings. Selection should account for end-application compliance requirements, particularly for automotive, industrial, and telecommunications applications where RoHS compliance may be mandatory.
