M50-3152242 Equivalent & Substitute Parts

Part Overview

The M50-3152242 is a 44-position rectangular receptacle connector from Harwin Inc.'s Archer M50 series, designed for surface mount applications with 0.050" (1.27mm) pitch mating. This connector features gold-plated contacts, push-pull fastening, and board guide support for board-to-board or cable interconnections. The part is classified as obsolete, making identification of active equivalent alternatives essential for ongoing design support and procurement.

Key Parameters

Substitute Part Grouping Explanation

The M50-3152242 has one manufacturer-recommended substitute: M50-3152542. The substitution is based on the following matching parameters:

• Same manufacturer (Harwin Inc.) and series (Archer M50)
• Identical mating pitch (0.050" / 1.27mm)
• Identical number of rows (2)
• Identical row spacing (0.050" / 1.27mm)
• Identical mounting type (Surface Mount)
• Identical contact finish (Gold)
• Identical current rating (1A)
• Identical operating temperature range (-40°C ~ 105°C)
• Identical insulation material (Polyamide PA6T, Nylon 6T)
• Identical contact material (Phosphor Bronze)
• Identical fastening type (Push-Pull)
• Identical board guide feature

The primary difference is the number of positions: the substitute part M50-3152542 provides 50 positions compared to the original 44 positions. This difference allows the substitute to serve applications requiring higher pin counts while maintaining full electrical and mechanical compatibility within the Archer M50 connector family.

Parameter Comparison

Engineering Selection Recommendations

The M50-3152542 is the active manufacturer-recommended substitute for the obsolete M50-3152242. Selection of the substitute part is supported by the following factors:

• The substitute maintains active product status with Harwin Inc., ensuring ongoing availability and manufacturing support
• Both parts carry identical ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements
• Electrical and mechanical specifications are fully aligned across all critical parameters including pitch, current rating, operating temperature, and contact materials
• The substitute's higher position count (50 vs. 44) provides design flexibility for applications requiring additional signal or power connections within the same connector footprint and mating interface

Frequently Asked Questions (FAQ)

Q: Can M50-3152542 directly replace M50-3152242 in existing designs?

A: The M50-3152542 is mechanically and electrically compatible with M50-3152242 across all shared parameters. The primary consideration is the increased position count (50 vs. 44). If your application uses only 44 positions, the substitute will function identically. If your design requires all 50 positions, the substitute provides additional capacity. PCB layout modifications may be necessary to accommodate the additional contact positions.

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

A: Compatibility is ensured through matching mating pitch (0.050"), row configuration (2 rows), mounting type (Surface Mount), contact finish (Gold), current rating (1A), operating temperature range (-40°C to 105°C), and fastening mechanism (Push-Pull). Both parts use identical insulation materials and contact materials.

Q: Are there packaging differences between the main part and substitute?

A: The M50-3152242 packaging is not specified in the available data. The M50-3152542 is supplied in Tube packaging. Confirm packaging requirements with your procurement process.

Q: Do both parts meet the same compliance standards?

A: Yes. Both M50-3152242 and M50-3152542 are ROHS3 compliant, REACH unaffected, carry UL94 V-0 flammability rating, and share identical ECCN (EAR99) and HTSUS classifications.

Q: What is the primary reason to use the substitute part?

A: The M50-3152242 is classified as obsolete. The M50-3152542 is the active equivalent from Harwin Inc., ensuring continued availability, manufacturing support, and compliance with current supply chain requirements.
