Key Parameters

Substitute Part Grouping Explanation

Substitution for the M50-3201145 is based on the following critical parameters that define functional compatibility:

Primary Substitution Criteria:

• Manufacturer: Harwin Inc.
• Series: Archer M50
• Connector Type: Receptacle
• Contact Type: Female Socket
• Pitch - Mating: 0.050" (1.27mm)
• Number of Rows: 2
• Row Spacing - Mating: 0.050" (1.27mm)
• Mounting Type: Through Hole, Right Angle
• Termination: Solder
• Contact Finish - Mating: Gold
• Current Rating: 1A
• Operating Temperature: -40°C ~ 105°C

The M50-3201245 qualifies as a substitute based on these parameters. The primary difference is the number of positions (24 versus 22), which represents an increase in contact capacity while maintaining all other electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

The M50-3201245 is the manufacturer-recommended substitute for the obsolete M50-3201145. Both connectors maintain identical electrical and mechanical specifications across all critical parameters including pitch, mounting configuration, contact materials, and operating temperature range. Both components are ROHS3 compliant and REACH unaffected, ensuring regulatory alignment.

The primary distinction is the position count: the M50-3201245 provides 24 positions compared to the 22 positions of the original part. This increased capacity does not affect compatibility with existing mating connectors or cable assemblies designed for the M50-3201145, as the additional positions extend the connector footprint without altering the core interface geometry.

The M50-3201245 carries Active product status, ensuring continued availability and supply chain support, whereas the M50-3201145 is obsolete. For new designs or system refreshes, the M50-3201245 is the appropriate selection.

Frequently Asked Questions (FAQ)

Q: Can the M50-3201245 directly replace the M50-3201145 in existing assemblies?

A: The M50-3201245 maintains all electrical and mechanical specifications of the M50-3201145. The 24-position configuration is compatible with existing mating connectors and cable assemblies designed for the 22-position original part. Physical board layout must accommodate the additional connector length resulting from the two additional positions.

Q: What is the physical size difference between these connectors?

A: Both connectors share identical row spacing (0.050"), insulation height (0.136"), and contact geometry. The M50-3201245 extends the connector length to accommodate two additional contact positions at the same 0.050" pitch.

Q: Are there any compliance or certification differences?

A: Both the M50-3201145 and M50-3201245 carry identical compliance certifications: UL94 V-0 flammability rating, ROHS3 compliance, and REACH unaffected status. No additional testing or qualification is required for substitution from a regulatory perspective.

Q: Why is the M50-3201145 obsolete?

A: The M50-3201145 has been superseded by the M50-3201245 within the Archer M50 product line. The manufacturer recommends the 24-position variant for all new applications.

Q: What packaging is available for the M50-3201245?

A: The M50-3201245 is supplied in Tube packaging, whereas the M50-3201145 packaging specification was not provided in the original documentation.
