Substitute Part Grouping Explanation

The M50-3501242 is identified as the manufacturer-recommended substitute for the M50-3501142. Substitution eligibility is determined by the following critical parameters:

• Pitch - Mating: Both parts maintain 1.27mm (0.050") pitch compatibility
• Manufacturer: Both parts are manufactured by Harwin Inc., ensuring design consistency within the Archer M50 series
• Connector Category: Both are rectangular connectors classified for board-to-board or cable applications
• Compliance Standards: Both parts maintain ROHS3 compliance and REACH Unaffected status
• Moisture Sensitivity: Both parts carry MSL 1 (Unlimited) rating

The M50-3501242 differs in position count (24 positions versus 22 positions) and product status (Active versus Obsolete). The increased position count represents a direct functional extension suitable for applications requiring additional contact capacity while maintaining identical pitch and electrical characteristics.

Parameter Comparison

Engineering Selection Recommendations

The M50-3501242 is the manufacturer-designated substitute for the M50-3501142. Both parts maintain identical pitch specifications (1.27mm) and are manufactured by Harwin Inc. within the Archer M50 series. The substitute part carries Active product status, ensuring continued availability and manufacturing support, whereas the original part is Obsolete.

Both parts satisfy ROHS3 compliance requirements and carry identical MSL 1 (Unlimited) ratings, confirming equivalent environmental and storage qualification. REACH Unaffected status is maintained across both parts.

The primary design consideration is the position count differential: the M50-3501242 provides 24 positions compared to the M50-3501142's 22 positions. This represents a functional extension rather than a reduction in capability. Applications requiring exactly 22 positions may require design modification to accommodate the 24-position configuration, or alternative sourcing strategies for remaining M50-3501142 inventory.

Frequently Asked Questions (FAQ)

Q: Can the M50-3501242 directly replace the M50-3501142 in existing designs?

A: Direct replacement is possible when the application can accommodate the increased position count (24 versus 22). The identical 1.27mm pitch and Harwin Inc. manufacturing ensure mechanical and electrical compatibility. Design review is required if the application is constrained to exactly 22 positions.

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

A: No. Both parts maintain ROHS3 compliance, REACH Unaffected status, and MSL 1 (Unlimited) ratings. Environmental and regulatory qualification is equivalent.

Q: Why is the M50-3501142 listed as Obsolete?

A: Obsolete status indicates the part is no longer in active production. The M50-3501242 represents the current active alternative within the Archer M50 series and is recommended for new designs and procurement.

Q: What is the significance of the 1.27mm pitch specification?

A: The 1.27mm (0.050") pitch is the center-to-center distance between adjacent contact positions. This specification must remain constant for mechanical and electrical compatibility. Both the original and substitute parts maintain this pitch, ensuring interchangeability at the connector interface level.

Q: Are there packaging differences between these parts?

A: The M50-3501242 is supplied in Box packaging. Packaging specifications for the M50-3501142 were not provided in the available data.
