M50-3114842 Equivalent & Substitute Parts

Part Overview

The M50-3114842 is a 96-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 is 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 component sourcing.

Substitute Part Grouping Explanation

The LPPB482NFSP-RC from Sullins Connector Solutions qualifies as a substitute based on the following critical parameters:

96-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
1A current rating
UL94 V-0 flammability rating
ROHS3 compliance
Moisture Sensitivity Level 1 (Unlimited)
Square contact geometry with phosphor bronze material

The substitute maintains electrical and mechanical compatibility through identical position count, pitch specifications, and contact characteristics. Both parts support push-pull fastening and board guide features.

Engineering Selection Recommendations

The LPPB482NFSP-RC is suitable for applications requiring M50-3114842 replacement based on the following factors:

The substitute part maintains ROHS3 compliance and UL94 V-0 flammability certification, meeting regulatory requirements equivalent to the original component. Both parts carry Moisture Sensitivity Level 1 classification, indicating no special handling requirements during storage or assembly.

The substitute operates across an extended temperature range (-40°C ~ 125°C versus -40°C ~ 105°C), providing additional thermal margin for demanding applications. The active product status of the LPPB482NFSP-RC ensures ongoing availability and manufacturing support, addressing the obsolescence of the original M50-3114842.

Electrical and mechanical parameters remain consistent: 96-position configuration, 0.050" pitch, 1A current rating, and gold-plated contacts with identical flash thickness. Both connectors employ phosphor bronze contact material and support identical push-pull fastening mechanisms.

Frequently Asked Questions (FAQ)

Q: What determines compatibility between M50-3114842 and LPPB482NFSP-RC?

A: Compatibility is established through matching position count (96), mating pitch (0.050"), row spacing (0.050"), mounting type (surface mount), contact finish (gold flash), current rating (1A), and fastening mechanism (push-pull). Both parts feature identical contact geometry and material composition.

Q: Why is the operating temperature range different between the two parts?

A: The LPPB482NFSP-RC operates to 125°C while the M50-3114842 operates to 105°C. This difference reflects different insulation material specifications (Liquid Crystal Polymer versus Polyamide). For applications within the original -40°C ~ 105°C range, both parts are functionally equivalent.

Q: Are there packaging differences between these connectors?

A: The M50-3114842 packaging is not specified in available data. The LPPB482NFSP-RC is supplied in tube packaging. Verify packaging requirements for your specific procurement and assembly processes.

Q: What is the significance of the connector type difference (Receptacle versus Header)?

A: The M50-3114842 is a receptacle (female socket), while the LPPB482NFSP-RC is a header with top or bottom entry capability. Both accommodate identical mating interfaces through their respective contact configurations. Verify mating connector compatibility with your system design.

Q: Do both parts meet the same regulatory standards?

A: Yes. Both the M50-3114842 and LPPB482NFSP-RC are ROHS3 compliant, UL94 V-0 rated, and REACH unaffected. Both carry EAR99 ECCN classification and identical HTSUS codes (8536.69.4040).
