Amphenol ICC 71920-308 Rectangular Connector - Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 71920-308 is an 8-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 tin-plated posts, with a push-pull fastening mechanism and UL94 V-0 rated thermoplastic insulation.

The 71920-308 is classified as obsolete. Identifying equivalent substitute parts is necessary to maintain design continuity and ensure component availability for production and field service applications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 71920-308 are determined by equivalence in the following critical parameters:

• Connector Type & Contact Configuration: Receptacle with female socket contacts
• Position Count & Pitch: 8 positions at 0.100" (2.54mm) mating pitch
• Electrical Interface: Board-to-board solder termination with through-hole mounting
• Contact Materials & Finishes: Gold-plated mating surface (30.0µin) and tin-plated posts (78.7µin)
• Mechanical Fastening: Push-pull mechanism
• Insulation Properties: UL94 V-0 rated thermoplastic with glass filler

The substitute parts listed maintain these core parameters while differing in specific attributes such as product status, packaging format, row configuration, and regulatory compliance status.

Parameter Comparison

Engineering Selection Recommendations

71920-308LF is the primary direct substitute for the obsolete 71920-308. Both parts maintain identical single-row, 8-position configuration with matching mechanical and electrical specifications. The 71920-308LF is currently in active production status with higher inventory availability. The primary distinction is regulatory compliance: the 71920-308LF is RoHS compliant and REACH affected, whereas the original part is RoHS non-compliant and REACH unaffected. Packaging differs (tube versus bulk), but functional performance is equivalent.

71991-304LF is a secondary substitute option with the same 8-position count and 0.100" pitch but differs in physical configuration: it features a 2-row arrangement instead of single-row, with reduced insulation height (0.275" versus 0.335") and slightly shorter post contact length (0.118" versus 0.122"). This part is suitable only when the 2-row footprint and reduced height are compatible with the target application. The 71991-304LF offers the highest inventory availability and active product status.

Selection between 71920-308LF and 71991-304LF depends on PCB layout constraints and mechanical fit requirements. For direct form-fit-function replacement, 71920-308LF is the appropriate choice.

Frequently Asked Questions (FAQ)

Q: Can the 71920-308LF be used as a direct replacement for the 71920-308?

A: Yes. The 71920-308LF maintains identical electrical and mechanical specifications including connector type, position count, pitch, contact materials, finishes, and fastening mechanism. The primary differences are product status (active versus obsolete), packaging format (tube versus bulk), and regulatory compliance (RoHS compliant versus non-compliant). Functional performance is equivalent.

Q: What is the key difference between the 71920-308LF and 71991-304LF?

A: The 71920-308LF is a single-row 8-position connector, while the 71991-304LF is a 2-row configuration with 4 positions per row. The 71991-304LF also has reduced insulation height (0.275" versus 0.335") and slightly shorter post contact length (0.118" versus 0.122"). These dimensional differences affect PCB footprint and mating stack height. The 71991-304LF is suitable only when the 2-row layout and reduced height are compatible with the design.

Q: Are there any compliance differences between these substitute parts?

A: Yes. The 71920-308 is RoHS non-compliant and REACH unaffected. Both substitute parts (71920-308LF and 71991-304LF) are RoHS compliant and REACH affected. If your application requires RoHS non-compliant components, the original 71920-308 must be used. For new designs or applications requiring RoHS compliance, either substitute part is appropriate.

Q: What is the mating pitch specification, and is it consistent across all three parts?

A: The mating pitch is 0.100" (2.54mm) for all three parts. This specification defines the center-to-center spacing between adjacent contact positions and is a critical parameter for connector compatibility. All substitute parts maintain this specification.

Q: How do the packaging formats differ, and does this affect functionality?

A: The 71920-308 is supplied in bulk packaging, while both 71920-308LF and 71991-304LF are supplied in tube packaging. Packaging format affects handling, storage, and component presentation but does not alter electrical or mechanical performance. Tube packaging provides better component protection during shipment and handling.

Q: Are the contact materials and finishes identical across all three parts?

A: Yes. All three parts use phosphor bronze contacts with gold-plated mating surfaces (30.0µin / 0.76µm thickness) and tin-plated posts (78.7µin / 2.00µm thickness). Contact material and finish specifications are identical, ensuring equivalent electrical performance and reliability.

Q: What does the "LF" designation in the part numbers indicate?

A: The "LF" suffix indicates lead-free construction, which is associated with RoHS compliance. Parts designated with "LF" (71920-308LF and 71991-304LF) are RoHS compliant, while the original 71920-308 without this designation is RoHS non-compliant.
