Amphenol ICC 71991-802 Rectangular Connector - Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 71991-802 is a 4-position receptacle connector with 0.100" (2.54mm) pitch, designed for board-to-board applications using through-hole solder termination. This part is classified as obsolete, making identification of equivalent and substitute components essential for ongoing system support and procurement planning. The Dubox™ series connector features gold-plated mating contacts and tin-plated posts, suitable for automotive, industrial, and telecommunications applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 71991-802 is determined by the following critical parameters:

• Connector Type & Contact Configuration: Receptacle with female socket contacts
• Pitch & Position Count: 0.100" (2.54mm) mating pitch with 4 positions in 2-row configuration
• Mounting & Termination: Through-hole solder termination
• Contact Materials & Finish: Phosphor bronze with gold mating finish (15.0µin) and tin post finish (78.7µin)
• Insulation Specifications: Thermoplastic glass-filled material, UL94 V-0 rated, blue color
• Physical Dimensions: 0.275" (6.99mm) insulation height, 11.04mm mated stacking height

Two substitute parts meet these criteria:

71991-802LF - Direct equivalent with identical electrical and mechanical specifications. Differs only in packaging (tube) and compliance status (RoHS compliant, REACH affected). Active product status provides long-term availability.

75867-303LF - Functionally compatible header connector with matching 0.100" (2.54mm) pitch and 2-row configuration. Differs in connector type (header vs. receptacle), position count (16 vs. 4), and mounting orientation (right-angle vs. straight entry). Suitable only where mating interface and position requirements permit.

Parameter Comparison

Engineering Selection Recommendations

71991-802LF is the primary substitute for the obsolete 71991-802. Both parts share identical electrical and mechanical specifications, including connector type, contact configuration, pitch, and physical dimensions. The 71991-802LF offers the advantage of active product status, ensuring continued availability and supply chain stability. The transition from RoHS non-compliant to RoHS compliant status aligns with current regulatory requirements. Packaging differs (tube vs. unspecified for original), but this does not affect functional compatibility. This part is suitable for direct replacement in all applications where the 71991-802 was originally specified.

75867-303LF is a functional substitute only in applications where the mating interface permits header-type connectors and where the 16-position configuration can be utilized or partially populated. This part operates at the same 0.100" (2.54mm) pitch and shares identical contact materials and finishes. However, the header connector type (male pins vs. female sockets), right-angle mounting orientation, and higher position count make this suitable only for redesigned or flexible mating scenarios. The Quickie™ series shrouded design with keying slot provides additional mechanical protection compared to the Dubox™ series.

Both substitute parts maintain UL94 V-0 flammability rating, MSL 1 moisture sensitivity, and identical contact finish specifications. Selection between 71991-802LF and 75867-303LF depends on whether the existing mating connector is a male pin header (compatible with 71991-802LF receptacle) or whether system redesign permits adoption of the 75867-303LF header configuration.

Frequently Asked Questions (FAQ)

Q: Can 71991-802LF be used as a direct replacement for 71991-802?

A: Yes. The 71991-802LF is electrically and mechanically identical to the 71991-802. Both are 4-position receptacles with 0.100" (2.54mm) pitch, female socket contacts, and identical contact materials and finishes. The primary differences are packaging format (tube) and compliance status (RoHS compliant). No circuit redesign or PCB layout modification is required.

Q: What are the key differences between 71991-802LF and 75867-303LF?

A: The 71991-802LF is a receptacle connector (female sockets) with 4 positions in straight-entry configuration. The 75867-303LF is a header connector (male pins) with 16 positions in right-angle configuration. While both operate at 0.100" (2.54mm) pitch and share identical contact materials, they are fundamentally different connector types. The 75867-303LF is suitable only if the mating interface is redesigned to accept a male pin header or if the additional positions can be utilized.

Q: Are there any compliance differences between the main part and substitutes?

A: Yes. The 71991-802 is RoHS non-compliant, while both 71991-802LF and 75867-303LF are RoHS compliant. Additionally, 71991-802LF is REACH affected, whereas the original part is REACH unaffected. For applications subject to RoHS or REACH regulations, the 71991-802LF is the appropriate choice. All three parts share identical ECCN (EAR99) and HTSUS (8536.69.4040) classifications.

Q: Does packaging affect the electrical or mechanical performance?

A: No. The 71991-802LF is supplied in tube packaging, while the original 71991-802 packaging is unspecified. Packaging format does not affect connector performance, electrical characteristics, or mechanical fit. Packaging selection is driven by inventory management, handling, and supply chain requirements.

Q: Can the 75867-303LF be used in a 4-position configuration?

A: The 75867-303LF is a 16-position connector. While individual positions could theoretically remain unpopulated, this approach is not recommended for production applications. The 71991-802LF remains the appropriate choice for 4-position requirements. The 75867-303LF should be selected only when the full 16-position capacity or header connector type is required by the application.

Q: What is the mated stacking height for each part?

A: The 71991-802 and 71991-802LF both specify 11.04mm mated stacking height. The 75867-303LF does not provide a mated stacking height specification, as this parameter is not applicable to header connectors in the same manner as receptacle connectors.

Q: Are all three parts suitable for automotive applications?

A: The 71991-802 and 71991-802LF are both listed for automotive applications. The 75867-303LF does not specify automotive applications in the provided data. For automotive-qualified designs, the 71991-802LF is the confirmed substitute. Use of 75867-303LF in automotive applications requires verification against specific application requirements and qualification standards.
