Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the M52-5113245 is determined by strict adherence to the following electrical and mechanical parameters:

Critical 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 Material: Polyamide (PA9T), Nylon 9T
• Contact Material: Phosphor Bronze
• Operating Temperature: -40°C ~ 105°C
• Current Rating: 1A

The M52-5112045 qualifies as a substitute based on matching all critical parameters. The primary difference is the number of positions: 40 positions versus the original 64 positions. This substitution is valid for applications where the reduced contact count meets system requirements.

Parameter Comparison

Engineering Selection Recommendations

The M52-5112045 is an active product from Harwin Inc., providing supply continuity for the obsolete M52-5113245. Both components maintain identical electrical and mechanical specifications across all critical parameters including pitch, row spacing, contact material, termination method, and operating temperature range.

Both parts carry ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment for current manufacturing standards. The MSL rating of 1 (Unlimited) indicates no moisture sensitivity constraints for either component.

Selection between these parts depends solely on the required number of contact positions. The M52-5112045 with 40 positions is suitable for applications requiring fewer signal or power connections than the original 64-position configuration.

Frequently Asked Questions (FAQ)

Q: Can the M52-5112045 directly replace the M52-5113245 in existing designs?

A: Direct replacement is possible only if the application requires 40 or fewer contact positions. The M52-5112045 maintains identical electrical and mechanical characteristics for all other parameters. PCB layout modifications may be necessary to accommodate the different position count.

Q: Are there any electrical performance differences between these connectors?

A: No. Both connectors share identical current rating (1A), operating temperature range (-40°C ~ 105°C), contact material (Phosphor Bronze), and contact finish (Gold). Electrical performance is equivalent.

Q: What is the significance of the product status difference?

A: The M52-5113245 is obsolete and no longer manufactured. The M52-5112045 is active production, ensuring availability for new designs and ongoing support. For applications currently using the 64-position connector, the 40-position substitute provides a path to active product sourcing.

Q: Are packaging differences relevant to the substitution?

A: The M52-5112045 is supplied in tube packaging. Packaging format does not affect electrical or mechanical compatibility. Verify packaging requirements for your procurement and assembly processes.

Q: Do both connectors meet the same compliance standards?

A: Yes. Both components are ROHS3 compliant, REACH unaffected, and carry UL94 V-0 flammability rating. Regulatory compliance is identical.
