Amphenol ICC 71920-304 Rectangular Connector - Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 71920-304 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 active equivalent and substitute parts essential for ongoing design support and procurement continuity. The connector features gold-plated mating contacts, tin-plated posts, and UL94 V-0 rated thermoplastic insulation suitable for automotive, industrial, and telecommunications applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the 71920-304 is determined by the following critical parameters:

• Connector Type & Style: Receptacle, board-to-board configuration
• Contact Configuration: 4-position, female socket contacts
• Pitch: 0.100" (2.54mm) mating pitch
• Mounting & Termination: Through-hole solder termination
• Contact Materials & Finish: Gold-plated mating surface, tin-plated posts
• Insulation Specifications: Thermoplastic, glass-filled, UL94 V-0 rated

Two substitute parts are identified:

1. 71920-304LF - Direct functional equivalent within the same Dubox™ series, maintaining identical electrical and mechanical specifications while offering active product status and improved compliance.

2. 71922-240LF - Alternative from the Quickie™ series with different connector architecture (header vs. receptacle, 40-position vs. 4-position), suitable only for applications where connector type flexibility is acceptable.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: 71920-304LF

The 71920-304LF is the direct functional equivalent for the obsolete 71920-304. Both parts maintain identical electrical and mechanical specifications within the Dubox™ series. The 71920-304LF offers the following advantages:

• Active product status ensures long-term availability and supply chain continuity
• RoHS compliant, meeting current regulatory requirements
• REACH affected status indicates compliance with chemical substance regulations
• Higher inventory availability (4626 units vs. 981 units)
• Identical connector architecture, pitch, contact configuration, and termination method

Alternative Substitute: 71922-240LF

The 71922-240LF from the Quickie™ series is structurally different and should be considered only when application requirements permit connector type modification. Key differences include:

• Header connector type (male pins) versus receptacle (female sockets)
• 40-position configuration versus 4-position
• Right-angle mounting orientation versus straight entry
• Different fastening mechanism (Latch Lock/Eject Hooks vs. Push-Pull)

This part is suitable only for applications where the connector interface can be redesigned to accommodate a header configuration.

Frequently Asked Questions (FAQ)

Q: Can 71920-304LF be used as a direct drop-in replacement for 71920-304?

A: Yes. The 71920-304LF maintains identical specifications for connector type, contact configuration, pitch, mounting method, and termination. No circuit board redesign is required.

Q: What is the significance of the "LF" suffix in 71920-304LF?

A: The "LF" designation indicates lead-free compliance, reflecting RoHS regulatory requirements. The base electrical and mechanical specifications remain unchanged from the non-LF version.

Q: Is 71922-240LF compatible with existing 71920-304 applications?

A: No. The 71922-240LF is a header connector with male pins and 40 positions, fundamentally different from the 4-position receptacle design of 71920-304. Circuit board redesign and mating connector replacement would be required.

Q: What are the packaging differences between the substitute parts?

A: 71920-304LF is supplied in bulk packaging, while 71922-240LF is supplied in tube packaging. Packaging selection depends on procurement volume and handling requirements.

Q: Are there compliance differences between 71920-304 and 71920-304LF?

A: Yes. The 71920-304 is RoHS non-compliant, while 71920-304LF is RoHS compliant. For applications subject to RoHS regulations, 71920-304LF is the required choice.

Q: What is the contact finish specification for mating surfaces?

A: Both 71920-304 and 71920-304LF use gold-plated mating contacts with 30.0µin (0.76µm) thickness. The 71922-240LF uses gold with GXT™ enhancement at the same thickness specification.

Q: Can these connectors be used interchangeably in automotive applications?

A: 71920-304 and 71920-304LF can be used interchangeably in automotive applications, as both are rated for this use. The 71922-240LF is not suitable without application redesign due to connector type differences.
