M50-3114642 Equivalent & Substitute Parts

Part Overview

The M50-3114642 is a 92-position receptacle connector manufactured by Harwin Inc. as part of the Archer M50 series. This surface mount, board-to-board connector features 0.050" (1.27mm) pitch with gold-plated mating contacts and push-pull fastening. The product is currently obsolete, making identification of compatible substitute components essential for ongoing system support and procurement planning.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the M50-3114642 is determined by strict alignment of the following electrical and mechanical parameters:

• Position Count & Pitch: 92 positions at 0.050" (1.27mm) mating pitch with 2-row configuration and 0.050" row spacing
• Mounting & Termination: Surface mount with solder termination
• Contact System: Gold-plated mating contacts with push-pull fastening
• Current & Temperature: 1A current rating with operating range of -40°C minimum
• Compliance: UL94 V-0 flammability rating and ROHS3 compliance

The LPPB462NFSP-RC from Sullins Connector Solutions meets these core substitution criteria. While differences exist in connector style (header vs. receptacle), insulation material (LCP vs. polyamide), and post contact finish, the mating interface parameters remain compatible for board-to-board applications.

Parameter Comparison

Engineering Selection Recommendations

The LPPB462NFSP-RC qualifies as a functional substitute based on matching mating interface specifications, current rating, and compliance certifications. The substitute maintains the critical 92-position, 0.050" pitch configuration with identical row spacing and gold-plated contact finish required for mating compatibility.

Key considerations for selection:

• Product Status: The substitute is active production, ensuring long-term availability compared to the obsolete M50-3114642
• Compliance: Both components meet UL94 V-0 flammability and ROHS3 requirements
• Operating Temperature: The substitute supports an extended upper temperature limit of 125°C versus 105°C for the original
• Insulation Material: The substitute uses liquid crystal polymer (LCP) instead of polyamide, offering improved dimensional stability and chemical resistance
• Connector Style: The substitute is a header configuration rather than receptacle; system design must accommodate this interface difference

Frequently Asked Questions (FAQ)

Q: Can the LPPB462NFSP-RC directly replace the M50-3114642 in existing designs?

A: The mating interface parameters are compatible. However, the connector style difference (header vs. receptacle) requires that the mating connector on the cable or board assembly be compatible with a header configuration. Physical board layout and mounting orientation must be evaluated.

Q: What is the significance of the different insulation materials?

A: The M50-3114642 uses polyamide (PA6T/Nylon 6T), while the LPPB462NFSP-RC uses liquid crystal polymer (LCP). Both materials meet UL94 V-0 flammability requirements. LCP offers superior dimensional stability and lower moisture absorption, which may improve long-term reliability in certain environmental conditions.

Q: Are the operating temperature ranges compatible?

A: The substitute supports -40°C to 125°C, exceeding the original specification of -40°C to 105°C. This provides additional thermal margin for applications operating near the upper temperature limit of the original component.

Q: What does "push-pull fastening" mean for this connector?

A: Push-pull fastening provides a mechanical locking mechanism that secures the mated connector pair. Both the original and substitute use this fastening type, ensuring consistent mating force and disconnection reliability.

Q: How do the contact finishes compare?

A: Both components feature gold flash plating on mating contacts. The substitute additionally specifies gold flash on post contacts, whereas the original specifies tin. This difference does not affect mating interface performance.

Q: What is the significance of MSL 1 (Unlimited) rating?

A: Moisture Sensitivity Level 1 indicates the component has unlimited shelf life without special moisture control measures. Both the original and substitute carry this rating, simplifying storage and handling requirements.
