Amphenol ICC 57202-S52-02 Rectangular Connector Header - Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 57202-S52-02 is a surface mount rectangular connector header from the Minitek® 2.00mm series. This is a 4-position, 2-row board-to-board header with male pins, designed for solder termination and push-pull fastening. The part is currently obsolete, making identification of suitable substitutes essential for ongoing design support and component procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the 57202-S52-02 is determined by strict equivalence across the following critical parameters:

• Connector type (Header)
• Contact type (Male Pin)
• Pitch and row spacing (0.079" / 2.00mm)
• Number of positions and rows (4 positions, 2 rows)
• Mounting type (Surface Mount)
• Termination method (Solder)
• Electrical ratings (2A, 200V AC/DC)
• Material flammability (UL94 V-0)
• Series compatibility (Minitek® 2.00mm)

The 57202-S52-02LF meets all these criteria and is classified as a direct substitute.

Parameter Comparison

Engineering Selection Recommendations

The 57202-S52-02LF is the direct substitute for the obsolete 57202-S52-02. Both parts are electrically and mechanically identical across all functional parameters. The primary distinction is product status and regulatory compliance:

The original 57202-S52-02 is obsolete and RoHS non-compliant. The 57202-S52-02LF is an active product with RoHS compliance and REACH applicability, making it the appropriate choice for new designs and ongoing production support. The "LF" designation indicates lead-free compliance, aligning with current environmental and regulatory standards.

For applications requiring the Minitek® 2.00mm 4-position, 2-row surface mount header with 2A/200V ratings and UL94 V-0 flammability rating, the 57202-S52-02LF provides full functional equivalence with improved regulatory standing.

Frequently Asked Questions (FAQ)

Q: Can the 57202-S52-02LF be used as a direct replacement for the 57202-S52-02?

A: Yes. Both parts share identical electrical ratings (2A, 200V AC/DC), mechanical dimensions (4 positions, 2 rows, 2.00mm pitch), contact materials and finishes, and flammability certification (UL94 V-0). The parts are functionally interchangeable at the circuit level.

Q: What does the "LF" suffix indicate?

A: The "LF" designation indicates lead-free compliance. The 57202-S52-02LF meets RoHS requirements, whereas the original 57202-S52-02 does not.

Q: Are there packaging differences between these parts?

A: The 57202-S52-02LF is supplied in Box packaging. Packaging format does not affect electrical or mechanical compatibility.

Q: Why is the original part listed as obsolete?

A: The 57202-S52-02 has been superseded by the RoHS-compliant 57202-S52-02LF variant. Amphenol ICC has transitioned production to the lead-free version to align with regulatory requirements.

Q: Are the contact finishes identical?

A: Yes. Both parts feature gold-plated mating contacts (GXT™ finish, 15.0µin thickness) and tin-plated posts (78.7µin thickness). Contact material is copper alloy in both cases.

Q: What is the moisture sensitivity level for these parts?

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