M50-3113142 Equivalent & Substitute Parts

Part Overview

The M50-3113142 is a 62-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 identification of compatible substitute components essential for ongoing system support and procurement.

Substitute Part Grouping Explanation

Substitution of the M50-3113142 is determined by strict alignment of the following critical parameters:

Connector Position Count: 62 positions (non-negotiable)
Mating Pitch: 0.050" (1.27mm) (non-negotiable)
Row Configuration: 2 rows with 0.050" (1.27mm) row spacing (non-negotiable)
Mounting Technology: Surface mount (non-negotiable)
Contact Finish: Gold plating on mating surfaces (non-negotiable)
Fastening Mechanism: Push-pull engagement (non-negotiable)
Current Capacity: 1A minimum (non-negotiable)
Regulatory Compliance: UL94 V-0 flammability and ROHS3 compliance (non-negotiable)

The LPPB312NFSP-RC from Sullins Connector Solutions meets all critical substitution criteria. While the substitute features a header connector type (top or bottom entry) rather than a receptacle, both components are designed for board-to-board mating with identical pitch, position count, row spacing, and electrical ratings. The substitute maintains gold contact finish, push-pull fastening, surface mount configuration, and equivalent regulatory compliance.

Engineering Selection Recommendations

The LPPB312NFSP-RC is the manufacturer-recommended substitute for the obsolete M50-3113142. Selection of this substitute is supported by the following factors:

Product Status Alignment: The substitute is active production status, ensuring long-term availability and supply chain continuity.
Regulatory Compliance: Both components maintain UL94 V-0 flammability certification and ROHS3 compliance, meeting equivalent safety and environmental standards.
Electrical Equivalence: Identical current rating (1A), contact finish (gold flash), and mating pitch (0.050") ensure electrical performance parity.
Mechanical Compatibility: Matching position count (62), row configuration (2 rows, 0.050" spacing), and fastening type (push-pull) provide direct mechanical interchangeability in board-to-board applications.
Temperature Performance: The substitute supports an extended operating temperature range (-40°C ~ 125°C) compared to the original (-40°C ~ 105°C), providing additional thermal margin.

Frequently Asked Questions (FAQ)

Q: Can the LPPB312NFSP-RC directly replace the M50-3113142 in existing designs?

A: Yes, for board-to-board mating applications. Both connectors share identical mating pitch (0.050"), position count (62), row spacing (0.050"), and fastening mechanism (push-pull). The primary difference is connector type: the original is a receptacle while the substitute is a header. Compatibility depends on the mating connector type in your system.

Q: What is the difference between a receptacle and a header connector?

A: A receptacle connector accepts pins from a mating header connector. A header connector provides the pins. In board-to-board applications, one board typically uses a receptacle while the mating board uses a header. Substitution requires that your system's mating connector is compatible with the header type.

Q: Are there any temperature limitations when using the substitute?

A: The substitute operates across -40°C ~ 125°C, which exceeds the original specification of -40°C ~ 105°C. If your application operates within the original temperature range, the substitute provides additional thermal margin. If your application requires operation above 105°C, verify that the substitute's extended range meets your requirements.

Q: What packaging is available for the LPPB312NFSP-RC?

A: The substitute is supplied in tube packaging, suitable for automated assembly processes and manual handling.

Q: Are both components RoHS compliant?

A: Yes. Both the M50-3113142 and LPPB312NFSP-RC are ROHS3 compliant and REACH unaffected, meeting current environmental regulations for electronic components.

Q: What is the moisture sensitivity level for these connectors?

A: Both components have a moisture sensitivity level (MSL) of 1, indicating unlimited shelf life without special moisture control measures during storage and handling.
