Key Parameters

Substitute Part Grouping Explanation

Substitution of the M50-3200245 is based on maintaining compatibility across the following critical parameters:

Preserved Parameters (Must Match):

• 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
• Contact Finish Thickness - Mating: 10.0µin (0.25µm)
• Insulation Material: Polyamide (PA9T), Nylon 9T
• Operating Temperature: -40°C ~ 105°C
• Current Rating: 1A
• Material Flammability Rating: UL94 V-0

Variable Parameter (Allows Substitution):

• Number of Positions: The substitute part may have a different position count while maintaining all other electrical and mechanical characteristics.

The M50-3200345 qualifies as a substitute because it maintains all critical connector interface parameters while offering an active product status with current manufacturing support.

Parameter Comparison

Engineering Selection Recommendations

The M50-3200345 is the designated substitute for the obsolete M50-3200245. Both components maintain identical electrical and mechanical interface specifications, including pitch, row spacing, contact finish, termination method, and operating temperature range. The M50-3200345 carries active product status with current manufacturing availability, ensuring long-term supply chain continuity.

Both parts maintain ROHS3 compliance and UL94 V-0 flammability certification, meeting regulatory requirements for general purpose, medical, and telecommunications applications. The primary difference is the increased position count (6 positions versus 4 positions) in the substitute part, which does not affect compatibility with existing mating connectors or cable assemblies designed for the Archer M50 series interface.

Frequently Asked Questions (FAQ)

Q: Can the M50-3200345 directly replace the M50-3200245 in existing designs?

A: The M50-3200345 maintains all critical electrical and mechanical interface parameters of the M50-3200245, including pitch, row spacing, contact finish, and termination method. The increased position count does not affect mating compatibility with standard Archer M50 series plugs or cable assemblies. Design review is necessary to confirm that the additional positions do not create physical or functional conflicts in the specific application.

Q: What is the primary reason for substitution?

A: The M50-3200245 is obsolete and no longer manufactured. The M50-3200345 is an active product from the same manufacturer and series, offering equivalent interface specifications and regulatory compliance.

Q: Are there any compliance or certification differences between these parts?

A: Both parts are ROHS3 compliant and carry UL94 V-0 flammability certification. No compliance differences exist between the two components.

Q: What is the packaging difference?

A: The M50-3200245 packaging information is not specified. The M50-3200345 is supplied in tube packaging.

Q: Are the contact materials and finishes identical?

A: Yes. Both parts use phosphor bronze contacts with 10.0µin (0.25µm) gold plating on both mating and post surfaces. Contact finish specifications are identical.
