M50-4304645 Equivalent & Substitute Parts

Part Overview

The M50-4304645 is a 92-position receptacle connector from Harwin Inc.'s Archer M50 series, designed for board-to-board applications with 0.050" (1.27mm) pitch spacing. This surface mount connector features gold-plated contacts, push-pull fastening, and operates across -40°C to 105°C. The part is classified as obsolete, making identification of active equivalent components essential for ongoing production and maintenance applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution within the Archer M50 series is determined by the following critical parameters: connector type (receptacle), contact type (female socket), pitch spacing (0.050"), mounting method (surface mount), fastening mechanism (push-pull), and material specifications (phosphor bronze contacts with gold plating, LCP insulation).

The M50-4302545 qualifies as a substitute based on matching these core electrical and mechanical parameters. However, this substitute differs in position count: the M50-4302545 provides 50 positions versus the 92 positions of the main part. This reduction in position capacity represents the primary design trade-off in this substitution relationship.

Both parts maintain identical pitch spacing, row configuration (2 rows), contact materials, operating temperature range, current rating, and fastening characteristics. The substitute part is classified as active product status, whereas the main part is obsolete.

Parameter Comparison

Engineering Selection Recommendations

The M50-4302545 serves as the active equivalent for the obsolete M50-4304645 within the Archer M50 connector family. Both parts maintain full compliance with ROHS3 and REACH requirements, ensuring regulatory alignment for current applications.

Selection of the M50-4302545 is appropriate when circuit design accommodates the reduced 50-position capacity. The substitute part's active product status ensures ongoing availability and manufacturing support, addressing the obsolescence constraint of the main part.

Applications requiring the full 92-position configuration cannot use this substitute without circuit redesign. In such cases, alternative connector families or custom solutions must be evaluated outside the Archer M50 series parameters provided.

Frequently Asked Questions (FAQ)

Q: Can the M50-4302545 directly replace the M50-4304645 in existing designs?

A: Direct replacement is possible only if the circuit design requires 50 or fewer positions. The M50-4302545 maintains identical electrical and mechanical characteristics (pitch, contact material, operating temperature, current rating, fastening type) but provides reduced position count. Designs utilizing all 92 positions of the original part cannot use this substitute without modification.

Q: What are the key compatibility factors between these parts?

A: Compatibility is determined by pitch spacing (0.050"), contact type (female socket), mounting method (surface mount), fastening mechanism (push-pull), and operating environment (-40°C to 105°C). Both parts share these specifications. The position count difference is the primary design consideration.

Q: Why is the M50-4304645 classified as obsolete?

A: Product status reflects manufacturer lifecycle decisions. The M50-4302545 is the active alternative within the same series, providing equivalent electrical performance with reduced position capacity.

Q: Are there packaging differences between these parts?

A: The M50-4302545 is supplied in tube packaging. Packaging specifications for the M50-4304645 were not provided in the available data.

Q: Do both parts meet the same compliance standards?

A: Yes. Both parts are ROHS3 compliant, REACH unaffected, UL94 V-0 rated, and maintain MSL 1 (unlimited) moisture sensitivity levels.
