Key Parameters

Substitute Part Grouping Explanation

Substitution of the M52-5100745 is determined by the following critical parameters that must remain consistent:

• Manufacturer Series: Archer M52 (ensures mechanical and electrical compatibility within the same connector family)
• Connector Type: Receptacle (maintains board-to-board mating interface)
• Pitch - Mating: 0.050" (1.27mm) (ensures contact alignment and spacing compatibility)
• Number of Rows: 2 (preserves row configuration)
• Row Spacing - Mating: 0.100" (2.54mm) (maintains inter-row distance)
• Mounting Type: Through Hole (preserves PCB assembly method)
• Termination: Solder (maintains soldering process compatibility)
• Contact Finish - Mating: Gold (ensures electrical performance and corrosion resistance)
• Current Rating: 1A (maintains electrical capacity)
• Operating Temperature: -40°C ~ 105°C (preserves thermal operating range)

The M52-5101045 qualifies as a substitute based on these parameters. The primary difference is the number of positions (20 vs. 14), which represents a higher-capacity variant within the same connector family. This substitution is valid for applications where additional contact positions can be accommodated or where the design can be adapted to utilize the expanded capacity.

Parameter Comparison

Engineering Selection Recommendations

The M52-5101045 is the recommended substitute for the obsolete M52-5100745. Both connectors maintain identical electrical and mechanical specifications across all critical parameters, including pitch, row spacing, contact material, current rating, and operating temperature range.

The M52-5101045 offers the advantage of active product status, ensuring ongoing availability and supply chain support. The 20-position configuration provides expanded capacity compared to the 14-position original, allowing for future design flexibility or increased signal routing capability.

Both parts maintain full compliance with RoHS3 and REACH regulations, with identical flammability ratings (UL94 V-0) and moisture sensitivity levels (MSL 1). The substitute part is available in tube packaging with 933 units in stock.

Frequently Asked Questions (FAQ)

Q: Can the M52-5101045 directly replace the M52-5100745 in existing designs?

A: The M52-5101045 is mechanically and electrically compatible with the M52-5100745 due to identical pitch, row spacing, contact materials, and electrical ratings. However, the increased position count (20 vs. 14) requires PCB layout verification to ensure the connector footprint accommodates the larger form factor.

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

A: The primary difference is the number of contact positions. The M52-5100745 provides 14 positions, while the M52-5101045 provides 20 positions. All other electrical and mechanical parameters remain identical.

Q: Are there any compliance or certification differences?

A: No. Both connectors maintain identical compliance certifications: RoHS3, REACH Unaffected, UL94 V-0 flammability rating, and MSL 1 moisture sensitivity level.

Q: What is the packaging difference?

A: The M52-5100745 packaging information was not specified in the original documentation. The M52-5101045 is supplied in tube packaging.

Q: Why is the M52-5100745 obsolete?

A: The M52-5100745 is classified as obsolete by the manufacturer. The M52-5101045, with active product status, represents the current equivalent offering within the Archer M52 series.
