Key Parameters

Substitute Part Grouping Explanation

The LPPB412NFSP-RC from Sullins Connector Solutions qualifies as a substitute based on the following critical parameters:

• 82-position configuration matching the original part
• 0.050" (1.27mm) mating pitch and row spacing
• Surface mount termination with solder connection
• Gold-plated mating contacts with flash thickness
• Push-pull fastening mechanism
• Square contact geometry with phosphor bronze material
• UL94 V-0 flammability rating
• ROHS3 compliance and unlimited moisture sensitivity level (MSL 1)

The substitute maintains electrical and mechanical compatibility through identical position count, pitch specifications, and contact characteristics. Both parts support the same current rating of 1A and operate within overlapping temperature ranges suitable for the specified applications.

Parameter Comparison

Engineering Selection Recommendations

The LPPB412NFSP-RC is suitable as a substitute for the obsolete M50-3114142 based on product status and compliance considerations. The Sullins part maintains active product status, ensuring ongoing availability and manufacturing support. Both parts achieve ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements for electronics manufacturing.

The substitute operates across a wider temperature range (-40°C ~ 125°C versus -40°C ~ 105°C), providing additional thermal margin for applications requiring extended operating conditions. Both connectors maintain identical electrical specifications including 1A current rating and equivalent contact geometry, ensuring functional interchangeability in board-to-board configurations.

Frequently Asked Questions (FAQ)

Q: What are the critical parameters for substituting the M50-3114142?

A: The 82-position count, 0.050" (1.27mm) pitch, surface mount configuration, and gold-plated contacts are the primary parameters determining substitution compatibility. The LPPB412NFSP-RC matches all these specifications.

Q: Are there differences in connector type between the main part and substitute?

A: The M50-3114142 is specified as a receptacle, while the LPPB412NFSP-RC is a header with top or bottom entry capability. Both are designed for board-to-board applications and maintain compatible mating interfaces through identical pitch and position specifications.

Q: What is the temperature operating range difference?

A: The M50-3114142 operates from -40°C to 105°C, while the LPPB412NFSP-RC operates from -40°C to 125°C. The substitute provides a 20°C higher upper temperature limit, suitable for applications requiring extended thermal performance.

Q: Are both parts compliant with current regulatory standards?

A: Yes. Both the M50-3114142 and LPPB412NFSP-RC are ROHS3 compliant and REACH unaffected, meeting current electronics manufacturing regulations.

Q: What is the packaging difference?

A: The M50-3114142 packaging is not specified in available data. The LPPB412NFSP-RC is supplied in tube packaging. Confirm packaging requirements with your procurement specifications.

Q: Do both connectors support the same current rating?

A: Yes. Both parts are rated for 1A current, maintaining identical electrical capacity for the application.
