Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the M52-5003145 is determined by strict adherence to the following parameters:

• Manufacturer Series: Must be Archer M52 to ensure mechanical and electrical compatibility
• Connector Type: Must be Receptacle
• Contact Type: Must be Forked
• Pitch - Mating: Must be 0.050" (1.27mm)
• Mounting Type: Must be Through Hole
• Termination: Must be Solder
• Fastening Type: Must be Push-Pull
• Contact Finish: Must be Gold on both mating and post surfaces
• Insulation Material: Must be Polyamide (PA6T), Nylon 6T
• Current Rating: Must be 1A
• Operating Temperature Range: Must be -40°C ~ 105°C
• Compliance: Must maintain ROHS3 Compliant and REACH Unaffected status

The M52-5001645 qualifies as a substitute based on these parameters. The primary difference is the number of positions (16 versus 31), which represents a reduced-capacity variant within the same connector family.

Parameter Comparison

Engineering Selection Recommendations

The M52-5001645 is an active product within the Archer M52 series and maintains full compliance with ROHS3 and REACH requirements. As an active component, it offers superior supply chain availability compared to the obsolete M52-5003145. Both connectors share identical electrical and mechanical specifications across all critical parameters including pitch, contact type, termination method, and operating temperature range.

Selection of the M52-5001645 as a substitute is appropriate for applications where the 16-position configuration meets functional requirements. For applications requiring the full 31-position capacity, alternative solutions within the Archer M52 series should be evaluated based on availability and product status.

Frequently Asked Questions (FAQ)

Q: Can the M52-5001645 directly replace the M52-5003145 in existing designs?

A: Direct replacement is possible only if the application requires 16 or fewer signal connections. The M52-5001645 maintains identical mechanical and electrical characteristics for all shared parameters. PCB layout modifications may be necessary if the original design utilizes all 31 positions.

Q: What is the primary difference between these two connectors?

A: The M52-5003145 provides 31 contact positions, while the M52-5001645 provides 16 contact positions. All other specifications, including pitch, contact type, termination, and operating characteristics, are identical.

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

A: Both connectors maintain identical compliance status: ROHS3 Compliant, REACH Unaffected, UL94 V-0 flammability rating, and MSL 1 (Unlimited) moisture sensitivity level.

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

A: The M52-5003145 is obsolete, indicating discontinued manufacturing and limited availability. The M52-5001645 is active, ensuring ongoing production and reliable supply chain access.

Q: Are the mated stacking heights identical?

A: Yes, both connectors share identical mated stacking heights of 7.1mm and 8.37mm, ensuring compatible board-to-board spacing in applications where both are used.

Q: What packaging format is available for the M52-5001645?

A: The M52-5001645 is supplied in Tube packaging, suitable for automated assembly and manual handling applications.
