M52-5103145 Equivalent & Substitute Parts

Part Overview

The M52-5103145 is a 62-position receptacle connector from Harwin Inc.'s Archer M52 series, designed for board-to-board applications with 0.050" (1.27mm) pitch spacing. This connector features gold-plated forked contacts, through-hole solder termination, and push-pull fastening. The product is currently obsolete, making identification of compatible substitute components essential for ongoing system support and new design implementations.

Substitute Part Grouping Explanation

The M52-5103045 is identified as a manufacturer-recommended substitute for the M52-5103145. Substitution eligibility is determined by the following critical parameters that must remain consistent:

Mandatory Matching Parameters:

• Manufacturer: Harwin Inc.
• Series: Archer M52
• Connector Type: Receptacle
• Contact Type: Forked
• Style: Board to Board
• Pitch - Mating: 0.050" (1.27mm)
• Number of Rows: 2
• Row Spacing - Mating: 0.100" (2.54mm)
• Mounting Type: Through Hole
• Termination: Solder
• Fastening Type: Push-Pull
• Contact Finish - Mating: Gold
• Insulation Height: 0.181" (4.60mm)
• Contact Length - Post: 0.118" (3.00mm)
• Operating Temperature: -40°C ~ 105°C
• Current Rating: 1A
• Insulation Material: Polyamide (PA6T), Nylon 6T
• Contact Material: Phosphor Bronze
• RoHS Status: ROHS3 Compliant

Variation Parameter:

• Number of Positions: 62 (main part) vs. 60 (substitute)

The M52-5103045 differs only in position count, reducing from 62 to 60 positions while maintaining all other electrical, mechanical, and environmental specifications.

Parameter Comparison

Engineering Selection Recommendations

The M52-5103045 is the active production equivalent for the obsolete M52-5103145. Both connectors maintain identical electrical and mechanical specifications across all critical parameters including pitch, row spacing, contact materials, termination method, and operating temperature range. Both components are ROHS3 compliant and suitable for general purpose, medical, and telecommunications applications.

The primary distinction is the reduction in position count from 62 to 60 positions. This substitution is appropriate for applications where the full 62-position capacity is not required. The M52-5103045 is currently in active production status with available inventory, whereas the M52-5103145 is obsolete.

Frequently Asked Questions (FAQ)

Q: Can the M52-5103045 directly replace the M52-5103145 in existing designs?

A: The M52-5103045 is electrically and mechanically compatible with the M52-5103145 across all shared specifications. However, the reduction from 62 to 60 positions requires verification that your application does not utilize all 62 contact positions. If your design uses 60 or fewer positions, direct substitution is valid.

Q: What is the physical difference between these connectors?

A: Both connectors share identical pitch (0.050"), row spacing (0.100"), insulation height (0.181"), and contact length specifications. The only physical difference is the total number of contact positions: 62 versus 60.

Q: Are both connectors suitable for medical applications?

A: Yes. Both the M52-5103145 and M52-5103045 are listed for medical applications and maintain identical operating temperature ranges (-40°C ~ 105°C) and material flammability ratings (UL94 V-0).

Q: What is the packaging difference?

A: The M52-5103045 is supplied in tube packaging, whereas packaging information for the M52-5103145 is not specified in the technical data.

Q: Why is the M52-5103145 obsolete?

A: The M52-5103145 has been discontinued by the manufacturer. The M52-5103045 represents the active production alternative within the Archer M52 series.
