M50-3112642 Equivalent & Substitute Parts

Part Overview

The M50-3112642 is a 52-position receptacle connector manufactured by Harwin Inc. as part of the Archer M50 series. This surface mount connector features 0.050" (1.27mm) pitch, gold-plated mating contacts, and push-pull fastening, designed for board-to-board or cable applications in general purpose, medical, and telecommunications environments. The product is currently obsolete, making equivalent substitute parts necessary for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

The LPPB262NFSP-RC from Sullins Connector Solutions qualifies as a substitute for the M50-3112642 based on the following critical parameters:

• Connector Position Count: Both parts feature 52 positions
• Mating Pitch: Both maintain 0.050" (1.27mm) pitch spacing
• Row Configuration: Both use 2-row layout with 0.050" (1.27mm) row spacing
• Mounting Technology: Both are surface mount connectors
• Contact Finish: Both feature gold-plated mating contacts
• Fastening Mechanism: Both employ push-pull fastening
• Current Rating: Both rated for 1A
• Compliance Standards: Both are ROHS3 compliant and REACH unaffected
• Moisture Sensitivity: Both rated MSL 1 (Unlimited)

The substitution is valid within the electrical and mechanical constraints of the 52-position, 0.050" pitch rectangular connector category.

Parameter Comparison

Engineering Selection Recommendations

The LPPB262NFSP-RC is suitable as a substitute for the obsolete M50-3112642 in applications requiring 52-position, 0.050" pitch rectangular connectors with surface mount termination. Both parts meet ROHS3 compliance and UL94 V-0 flammability requirements, ensuring regulatory alignment for medical and telecommunications applications.

The LPPB262NFSP-RC offers an extended operating temperature range (-40°C ~ 125°C versus -40°C ~ 105°C), providing additional thermal margin in high-temperature environments. The active product status of the Sullins connector ensures ongoing availability and supply chain continuity compared to the obsolete Harwin part.

Mechanical compatibility is established through identical pitch spacing, row configuration, and push-pull fastening mechanisms. Both connectors employ phosphor bronze contacts with gold plating and support equivalent current ratings.

Frequently Asked Questions (FAQ)

Q: What makes LPPB262NFSP-RC a valid substitute for M50-3112642?

A: Both connectors share identical critical parameters: 52 positions, 0.050" (1.27mm) mating pitch, 2-row configuration with 0.050" row spacing, surface mount technology, push-pull fastening, 1A current rating, and equivalent compliance certifications (ROHS3, UL94 V-0, MSL 1).

Q: Are there differences in connector style between these parts?

A: The M50-3112642 is a receptacle connector, while the LPPB262NFSP-RC is a header with top or bottom entry capability. Both are designed for board-to-board applications and maintain mechanical and electrical compatibility through identical pitch and position specifications.

Q: What is the temperature operating range difference?

A: The M50-3112642 operates from -40°C to 105°C, while the LPPB262NFSP-RC operates from -40°C to 125°C. The Sullins connector provides a 20°C higher upper temperature limit, suitable for applications requiring extended thermal performance.

Q: Are both connectors RoHS compliant?

A: Yes, both the M50-3112642 and LPPB262NFSP-RC are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronics manufacturing.

Q: What is the packaging format for the substitute part?

A: The LPPB262NFSP-RC is supplied in tube packaging, suitable for automated assembly and component handling in production environments.

Q: Can these connectors be used interchangeably in existing designs?

A: Substitution is valid within the electrical and mechanical constraints of the 52-position, 0.050" pitch rectangular connector category. Design verification should confirm compatibility with the specific mating connector and application requirements.
