Amphenol ICC 71920-320 Rectangular Connector - Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 71920-320 is a 20-position receptacle connector from the Dubox™ series, designed for board-to-board applications with 0.100" (2.54mm) pitch through-hole mounting. This connector features gold-plated mating contacts and tin-plated posts for reliable solder termination in automotive, industrial, and telecommunications applications.

The 71920-320 carries an obsolete product status. Identifying equivalent and substitute parts is necessary to ensure design continuity, maintain supply chain reliability, and support legacy system maintenance and repairs.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 71920-320 is determined by the following critical parameters:

• Connector Type & Contact Configuration: Receptacle with female socket contacts
• Position Count: 20 positions
• Pitch Specification: 0.100" (2.54mm) mating pitch
• Mounting & Termination: Through-hole solder termination
• Contact Materials & Finish: Gold-plated mating surface with tin-plated posts
• Insulation Properties: Thermoplastic, glass-filled material with UL94 V-0 rating

The primary substitute identified is 71920-320LF, which maintains identical electrical and mechanical specifications while offering active product status and RoHS compliance. This part represents a direct functional equivalent with improved regulatory standing.

The secondary substitute 75160-102-03LF is a header connector from the BERGSTIK® series with fundamentally different connector architecture (male pin header vs. female receptacle) and reduced position count (3 positions vs. 20 positions). This part does not meet substitution criteria for direct replacement applications.

Parameter Comparison

Engineering Selection Recommendations

71920-320LF is the appropriate substitute for the obsolete 71920-320. Both parts share identical connector architecture, position count, pitch specification, and contact materials. The 71920-320LF offers the following advantages:

• Active product status ensures ongoing availability and manufacturing support
• RoHS compliance aligns with current regulatory requirements for new designs and procurement
• Identical electrical and mechanical specifications guarantee direct functional compatibility
• Tube packaging provides standard handling and storage options

75160-102-03LF is not suitable as a direct replacement. The fundamental differences in connector type (header vs. receptacle), contact gender (male vs. female), and position count (3 vs. 20) make this part incompatible with applications designed for the 71920-320.

Frequently Asked Questions (FAQ)

Q: Can 71920-320LF be used as a direct replacement for 71920-320?

A: Yes. The 71920-320LF maintains identical specifications for connector type, contact configuration, position count, pitch, mounting method, and contact materials. The primary difference is product status and regulatory compliance, with 71920-320LF offering active availability and RoHS compliance.

Q: What is the significance of the "LF" suffix in 71920-320LF?

A: The "LF" designation indicates lead-free compliance, reflecting the part's RoHS-compliant manufacturing process. This distinguishes it from the original 71920-320, which is RoHS non-compliant.

Q: Is 75160-102-03LF a viable alternative?

A: No. The 75160-102-03LF is a header connector with male pins and only 3 positions, whereas the 71920-320 is a 20-position receptacle with female sockets. These parts serve different connector roles and are not interchangeable.

Q: What packaging options are available?

A: The 71920-320 was supplied in standard packaging (not specified). The 71920-320LF is available in tube packaging, which is the standard format for active production parts.

Q: Are there any compliance considerations when switching from 71920-320 to 71920-320LF?

A: The 71920-320LF is RoHS compliant and REACH affected, whereas the original 71920-320 is RoHS non-compliant and REACH unaffected. For new designs or applications subject to RoHS regulations, the 71920-320LF is the required choice.
