M50-3114342 Equivalent & Substitute Parts

Part Overview

The M50-3114342 is an 86-position rectangular 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 identification of compatible substitute components essential for ongoing system support and procurement.

Key Parameters

Substitute Part Grouping Explanation

The LPPB432NFSP-RC from Sullins Connector Solutions qualifies as a substitute based on the following critical parameters:

• Connector Position Count: Both parts feature 86 positions
• Mating Pitch: Both maintain 0.050" (1.27mm) pitch spacing
• Row Configuration: Both are 2-row designs with 0.050" (1.27mm) row spacing
• Mounting Technology: Both are surface mount connectors
• Contact Material & Finish: Both use phosphor bronze contacts with gold mating finish
• Current Rating: Both are rated for 1A
• Fastening Type: Both employ push-pull fastening
• Compliance: Both are ROHS3 compliant and REACH unaffected

The primary distinction lies in connector style (receptacle versus header) and insulation material composition, which do not prevent functional substitution in board-to-board applications.

Parameter Comparison

Engineering Selection Recommendations

The LPPB432NFSP-RC is an active product with extended operating temperature range (-40°C ~ 125°C versus -40°C ~ 105°C), providing additional thermal margin for demanding applications. Both connectors maintain identical electrical specifications, pitch geometry, and compliance certifications (ROHS3, REACH unaffected, UL94 V-0). The substitute part's active product status ensures ongoing availability and supply chain continuity, addressing the obsolescence of the original M50-3114342. The insulation material difference (LCP versus PA6T nylon) does not affect electrical performance or mechanical compatibility in standard board-to-board configurations.

Frequently Asked Questions (FAQ)

Q: Can LPPB432NFSP-RC directly replace M50-3114342 in existing designs?

A: Yes, for board-to-board applications. Both connectors share identical 86-position count, 0.050" pitch, 2-row configuration, surface mount technology, and push-pull fastening. The connector style difference (receptacle versus header) requires mating connector compatibility verification.

Q: What is the primary reason for substitution?

A: The M50-3114342 is obsolete. The LPPB432NFSP-RC is an active product from Sullins Connector Solutions, ensuring procurement availability and supply chain reliability.

Q: Are there compliance differences between these parts?

A: No. Both connectors are ROHS3 compliant, REACH unaffected, and rated UL94 V-0 for material flammability.

Q: Does the insulation material change affect electrical performance?

A: No. The change from PA6T nylon to liquid crystal polymer (LCP) does not alter electrical characteristics, current rating (1A), or contact finish specifications.

Q: What is the temperature operating range difference?

A: The LPPB432NFSP-RC operates from -40°C to 125°C, compared to -40°C to 105°C for the M50-3114342. This provides 20°C additional upper temperature margin.

Q: Are the mating contact specifications identical?

A: Yes. Both use phosphor bronze contacts with gold flash finish, square contact geometry, and identical pitch spacing (0.050" mating pitch, 0.050" row spacing).

Q: What packaging format is the substitute available in?

A: The LPPB432NFSP-RC is supplied in tube packaging.
