Substitute Part Grouping Explanation

The M52-5152045 is identified as a manufacturer-recommended substitute for the M52-5153545. Both connectors share the same fundamental electrical and mechanical characteristics that define compatibility within the Archer M52 series:

Critical matching parameters:

• Pitch - Mating: 0.050" (1.27mm)
• Number of Rows: 2
• Row Spacing - Mating: 0.100" (2.54mm)
• Mounting Type: Surface Mount
• Termination: Solder
• Fastening Type: Push-Pull
• Contact Finish - Mating: Gold
• Operating Temperature: -40°C ~ 105°C
• Current Rating: 1A
• Material Flammability Rating: UL94 V-0
• Insulation Material: Polyamide (PA6T), Nylon 6T
• Contact Material: Phosphor Bronze

The primary difference is the number of positions: the substitute part provides 40 positions versus the original 70 positions. This substitution is applicable only when circuit designs can accommodate the reduced contact count.

Parameter Comparison

Engineering Selection Recommendations

The substitute part carries active product status, ensuring continued availability and manufacturing support.

Selection of the M52-5152045 is appropriate when circuit designs require 40 contact positions. The connector maintains full compatibility with the Archer M52 series ecosystem, including mating interface geometry, termination methodology, and environmental performance specifications. Both parts satisfy ROHS3 compliance and REACH regulatory requirements.

Frequently Asked Questions (FAQ)

Q: Can the M52-5152045 directly replace the M52-5153545 in existing designs?

A: Direct replacement is possible only if the circuit design requires 40 or fewer contact positions. The substitute part provides identical electrical and mechanical characteristics for all shared parameters. PCB layout modifications may be necessary to accommodate the reduced connector footprint.

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

A: The M52-5153545 provides 70 contact positions, while the M52-5152045 provides 40 contact positions. All other electrical, mechanical, and environmental specifications remain identical.

Q: Are the mating interfaces compatible between these parts?

A: Both connectors use identical 0.050" (1.27mm) pitch spacing and 0.100" (2.54mm) row spacing. Mating plug connectors designed for either part will not physically interface with the other due to the different position counts.

Q: What is the product status difference, and why does it matter?

A: The M52-5153545 is classified as obsolete, indicating discontinued manufacturing. The M52-5152045 maintains active product status, ensuring ongoing availability, manufacturing support, and compliance documentation.

Q: Are there packaging differences between these parts?

A: The M52-5152045 is supplied in tube packaging. Packaging specifications for the M52-5153545 were not provided in the available documentation.

Q: Do both connectors meet the same regulatory and compliance standards?

A: Both parts are ROHS3 compliant, REACH unaffected, and carry identical ECCN and HTSUS classifications. Both maintain UL94 V-0 material flammability ratings and identical moisture sensitivity levels.
