Key Parameters

Substitute Part Grouping Explanation

The M52-5152045 is identified as a manufacturer-recommended substitute for the M52-5153645. Substitution eligibility is determined by the following critical parameters that must remain consistent:

• Series: Both parts belong to the Archer M52 series
• Connector Type: Both are receptacle connectors with female socket contacts
• Pitch - Mating: Both maintain 0.050" (1.27mm) contact spacing
• Number of Rows: Both feature 2-row configuration
• Row Spacing - Mating: Both maintain 0.100" (2.54mm) row spacing
• Mounting Type: Both are surface mount connectors
• Termination: Both use solder termination
• Fastening Type: Both employ push-pull fastening
• Contact Finish - Mating: Both feature gold-plated mating surfaces
• Insulation Material: Both use Polyamide (PA6T), Nylon 6T
• Contact Material: Both use Phosphor Bronze contacts
• Operating Temperature: Both operate across -40°C ~ 105°C
• Current Rating: Both rated at 1A
• Material Flammability Rating: Both meet UL94 V-0
• RoHS Status: Both are ROHS3 Compliant
• Moisture Sensitivity Level: Both rated MSL 1 (Unlimited)

The primary difference is position count: M52-5152045 provides 40 positions versus the 72 positions of M52-5153645. This substitution is applicable only when system requirements permit reduced contact density.

Parameter Comparison

Engineering Selection Recommendations

The M52-5152045 is an active product within the same Archer M52 series, providing continuity for applications requiring reduced contact density. Selection of this substitute is appropriate when system design permits operation with 40 positions instead of 72. Both parts maintain identical electrical and mechanical specifications across all critical parameters including pitch, row spacing, operating temperature range, current rating, and contact materials.

The M52-5152045 offers the advantage of active product status, ensuring ongoing availability and supply chain support compared to the obsolete M52-5153645. Both parts satisfy identical compliance requirements: ROHS3 compliance, REACH unaffected status, UL94 V-0 flammability rating, and MSL 1 moisture sensitivity classification.

Frequently Asked Questions (FAQ)

Q: Can M52-5152045 directly replace M52-5153645 in existing designs?

A: Direct replacement is possible only if the application requires 40 or fewer signal connections. The M52-5152045 provides 40 positions versus 72 positions in the M52-5153645. PCB layout and connector footprint compatibility must be verified before implementation.

Q: Are the mating pitch and row spacing identical between these parts?

A: Yes. Both connectors maintain 0.050" (1.27mm) mating pitch and 0.100" (2.54mm) row spacing. These critical dimensional parameters are identical across both parts.

Q: What is the difference in product status between these parts?

A: M52-5153645 is obsolete, while M52-5152045 is active. The active status of M52-5152045 ensures continued manufacturing and supply availability.

Q: Do both parts meet the same environmental and compliance standards?

A: Yes. Both parts are ROHS3 compliant, REACH unaffected, rated UL94 V-0 for flammability, and classified as MSL 1 (unlimited moisture sensitivity). Operating temperature range is identical at -40°C to 105°C for both parts.

Q: What packaging is available for the substitute part?

A: M52-5152045 is supplied in tube packaging. Verify packaging requirements for your procurement and assembly processes.

Q: Are the contact materials and finishes the same?

A: Yes. Both parts feature phosphor bronze contacts with gold plating on mating surfaces. Contact finish thickness specifications are not provided for either part.
