Amphenol ICC 71920-402 Rectangular Connector - Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 71920-402 is a 2-position receptacle connector with 0.100" (2.54mm) pitch, designed for board-to-board applications using through-hole solder termination. This connector features tin-lead contact finish and is part of the Dubox™ series. The part is currently obsolete, making identification of suitable substitutes necessary for ongoing design support and component procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 71920-402 is determined by the following critical parameters:

• Connector Type & Position Count: Must be a 2-position receptacle, bottom or top entry
• Pitch Specification: Must maintain 0.100" (2.54mm) mating pitch
• Mounting & Termination: Must support through-hole solder termination
• Contact Configuration: Must use female socket contacts with square shape
• Insulation Properties: Must use thermoplastic, glass-filled insulation with UL94 V-0 rating
• Series Compatibility: Must be part of the Dubox™ series

The 71920-402LF meets all substitution criteria. The primary difference is the contact finish specification: the substitute uses tin finish instead of tin-lead finish, and carries active product status with RoHS compliance.

Parameter Comparison

Engineering Selection Recommendations

The 71920-402LF is the direct substitute for the obsolete 71920-402. Both parts maintain identical mechanical and electrical interface specifications, including connector type, position count, pitch, mounting method, and termination approach.

The key distinction is regulatory compliance: the 71920-402LF carries active product status and RoHS compliance, whereas the original part is obsolete and RoHS non-compliant. The contact finish difference (tin versus tin-lead) reflects the RoHS transition. Both finishes maintain the same thickness specification of 78.7µin (2.00µm) on mating and post surfaces.

For new designs or component replenishment, the 71920-402LF is the appropriate selection. Both parts share identical mechanical dimensions, insulation properties, and flammability ratings, ensuring direct compatibility in existing board layouts.

Frequently Asked Questions (FAQ)

Q: Can the 71920-402LF be used as a direct replacement for the 71920-402?

A: Yes. Both parts are mechanically and electrically compatible. They share identical pitch (0.100"), position count (2), mounting type (through-hole), termination method (solder), and insulation specifications. The primary difference is the contact finish and product status.

Q: What is the difference between tin-lead and tin contact finishes?

A: The 71920-402 uses tin-lead finish, while the 71920-402LF uses tin finish. Both maintain the same thickness of 78.7µin (2.00µm). The tin finish reflects RoHS compliance requirements. Both finishes are suitable for solder termination applications.

Q: Why is the original part marked as obsolete?

A: The 71920-402 is obsolete due to its RoHS non-compliant status. The 71920-402LF represents the active, RoHS-compliant equivalent within the Dubox™ series.

Q: Are there any packaging differences between these parts?

A: The 71920-402 packaging is not specified in the available data. The 71920-402LF is supplied in bulk packaging.

Q: Do both parts have the same moisture sensitivity level?

A: Yes. Both parts carry MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.

Q: Are the mechanical dimensions identical?

A: Yes. Both parts share identical insulation height (0.335"), contact length (0.122"), and all other mechanical specifications. They are fully interchangeable in board layouts.
