Key Parameters

Substitute Part Grouping Explanation

Substitution of the M50-3601642P is limited by the following critical parameters that must remain constant:

• Manufacturer and Series: Harwin Inc. Archer M50 family
• Connector Type and Contact Type: Header with male pins
• Pitch and Row Spacing: 0.050" (1.27mm) mating pitch and row spacing
• Mounting Type: Surface mount configuration
• Termination and Fastening: Solder termination with push-pull fastening
• Contact Finish: Gold-plated mating contacts
• Operating Temperature Range: -40°C ~ 105°C
• Current Rating: 1A per contact
• Compliance: UL94 V-0 and ROHS3 compliant

The M50-3600842 is identified as a manufacturer-recommended substitute. This part maintains compatibility across all critical electrical and mechanical parameters while differing in position count (16 positions versus 32 positions). The reduction in position count represents a functional subset of the original connector, suitable for applications requiring fewer interconnection points within the same form factor and electrical specifications.

Parameter Comparison

Engineering Selection Recommendations

The M50-3600842 is the manufacturer-recommended substitute for the obsolete M50-3601642P. Both parts maintain identical electrical and mechanical specifications across all critical parameters including pitch, row spacing, contact finish, operating temperature range, current rating, and compliance certifications.

The primary distinction is position count: the substitute provides 16 positions compared to the original 32 positions. Selection of the M50-3600842 is appropriate for applications requiring 16 or fewer interconnection points. For applications requiring the full 32-position configuration, alternative solutions within the Archer M50 series should be evaluated, or multiple 16-position connectors may be considered for the design.

The active product status of the M50-3600842 ensures ongoing availability and manufacturing support, addressing the obsolescence constraint of the original part.

Frequently Asked Questions (FAQ)

Q: Can the M50-3600842 be used as a direct replacement for the M50-3601642P?

A: The M50-3600842 is electrically and mechanically compatible with the M50-3601642P across all critical parameters. However, it provides 16 positions instead of 32. Direct replacement is possible only if your application requires 16 or fewer interconnection points.

Q: What are the key compatibility criteria for substitution?

A: Substitution within the Archer M50 series requires matching: 0.050" (1.27mm) mating pitch, 0.050" (1.27mm) row spacing, surface mount configuration, solder termination, push-pull fastening, and gold-plated mating contacts. Operating temperature range and current rating must also remain within -40°C ~ 105°C and 1A per contact.

Q: Are there compliance differences between these parts?

A: Both parts are UL94 V-0 rated and ROHS3 compliant. No compliance differences exist between the M50-3601642P and M50-3600842.

Q: What is the packaging difference?

A: The M50-3601642P is listed with unspecified packaging, while the M50-3600842 is supplied in bulk packaging. Confirm packaging requirements with your procurement process.

Q: Why is the M50-3601642P obsolete?

A: Product obsolescence is determined by the manufacturer. The active status of the M50-3600842 provides a supported alternative within the same connector family.
