Equivalent & Substitute Parts for 52601-G44-6

Part Overview

The Amphenol ICC 52601-G44-6 is a rectangular connector header with 44 vertical positions at 2.54mm pitch, designed for through-hole mounting with solder termination. This component is classified as obsolete, making identification of active equivalent parts essential for ongoing production and maintenance applications. Substitute parts must maintain electrical and mechanical compatibility while meeting current manufacturing and compliance standards.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 52601-G44-6 is determined by strict equivalence in the following critical parameters:

• Connector Type & Contact Configuration: Header with male pins
• Position Count & Arrangement: 44 positions in 2 rows
• Pitch Specifications: 0.100" (2.54mm) mating pitch and row spacing
• Mounting & Termination: Through-hole solder termination
• Shrouding Design: Shrouded 4-wall construction
• Contact Material & Finish: Phosphor bronze with gold mating surface
• Flammability Compliance: UL94 V-0 rating

The three substitute parts listed below meet all these core electrical and mechanical requirements. Variations in insulation material composition, contact post length, and compliance certifications are secondary parameters that do not affect functional interchangeability in standard applications.

Parameter Comparison

Engineering Selection Recommendations

66506-242LF (Amphenol ICC): This part maintains manufacturer continuity with the original 52601-G44-6 while offering active product status and RoHS compliance. The insulation material differs (polyester glass-filled versus thermoplastic), and contact post length is reduced to 0.105", which may require PCB design verification for solder joint depth. This option is suitable for applications requiring Amphenol ICC ecosystem compatibility.

0702464401 (Molex C-Grid 70246): This Molex alternative provides active status and ROHS3 compliance with established automotive, medical, and telecommunications application history. Contact finish thickness on the mating surface is reduced to 15.0µin (0.38µm) compared to the original 30.0µin specification. Contact post length is 0.135", intermediate between the original and 66506-242LF. This part is suitable for general-purpose and specialized industrial applications.

0702464402 (Molex C-Grid 70246): This variant matches the original contact finish thickness specification at 30.0µin (0.76µm) while maintaining all other Molex C-Grid 70246 characteristics. Contact post length remains at 0.135". This option provides the closest electrical performance match to the original part with modern compliance certifications.

Selection between substitute parts should prioritize application requirements for contact finish durability, PCB solder joint geometry, and regulatory compliance mandates.

Frequently Asked Questions (FAQ)

Q: Can 66506-242LF be used as a direct replacement for 52601-G44-6?

A: Yes, 66506-242LF is electrically and mechanically compatible. The primary design difference is the reduced contact post length (0.105" versus 0.150"), which affects solder joint formation depth on the PCB. Verify that your PCB design accommodates this shorter post length without compromising solder joint quality.

Q: What is the difference between 0702464401 and 0702464402?

A: Both are Molex C-Grid 70246 series parts with identical mechanical dimensions and mounting characteristics. The key difference is contact finish thickness on the mating surface: 0702464401 has 15.0µin (0.38µm) while 0702464402 has 30.0µin (0.76µm). For applications requiring extended contact life or higher mating cycle durability, 0702464402 is preferred.

Q: Are all three substitute parts RoHS compliant?

A: Yes. The original 52601-G44-6 is RoHS non-compliant. All three substitutes (66506-242LF, 0702464401, and 0702464402) are RoHS compliant, meeting current regulatory requirements for new designs and production.

Q: Do these parts have different packaging options?

A: Yes. The 66506-242LF is supplied in Tray packaging, while both Molex parts (0702464401 and 0702464402) are supplied in Bulk packaging. Confirm packaging compatibility with your procurement and assembly processes.

Q: Can I mix these substitute parts in the same assembly?

A: All three parts are mechanically and electrically interchangeable within the same assembly. However, mixing different manufacturers or contact finish specifications may introduce inconsistency in contact resistance and mating force characteristics. Standardize on a single part number per assembly for optimal performance consistency.

Q: What is the MSL rating for these parts?

A: All parts, including the original and all substitutes, have MSL 1 (Unlimited) rating, indicating no moisture sensitivity concerns for storage and handling.
