Molex 0873811263 Equivalent & Substitute Parts

Part Overview

The Molex 0873811263 is a 12-position receptacle connector in the Milli-Grid 87381 series, designed for board-to-board surface mount applications. This connector features 0.079" (2.00mm) pitch, gold-plated mating contacts, and push-pull fastening. The part is active in production and RoHS3 compliant with MSL 1 rating.

Substitute parts are identified when equivalent electrical and mechanical parameters are maintained, including connector pitch, position count, mounting type, contact finish, and operating specifications. Alternative sources provide equivalent functionality for applications requiring component availability or specific packaging formats.

Key Parameters

Substitute Part Grouping Explanation

Substitution validity is determined by strict equivalence in the following parameters:

• Connector pitch and position count: 0.079" (2.00mm) pitch with 12 positions in 2-row configuration
• Mounting and termination: Surface mount with solder termination
• Fastening mechanism: Push-pull fastening type
• Contact finish: Gold-plated mating contacts
• Board-to-board style: Designed for PCB-to-PCB interconnection

The substitute parts listed maintain these core parameters. Variations in connector type (receptacle vs. header), packaging format (tube vs. tape & reel), operating temperature range, voltage rating, and contact material do not preclude substitution when the above criteria are met. These variations represent alternative sourcing options suitable for equivalent circuit applications.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts maintain active production status and meet RoHS compliance requirements. Selection between alternatives depends on specific application constraints:

Amphenol ICC 55510-112LF and 55510-112TRLF are functionally equivalent receptacle connectors with identical electrical and mechanical specifications. The primary distinction is packaging format: tube packaging for 55510-112LF and tape & reel format for 55510-112TRLF. Tape & reel packaging is suitable for automated assembly processes, while tube packaging accommodates manual or semi-automated placement. Both parts support higher voltage ratings (200V) and extended operating temperature range (-55°C to 125°C) compared to the primary part.

Sullins NPPN062FFKP-RC and NPPN062FFKS-RC are header connectors rather than receptacles, maintaining equivalent pitch, position count, and mounting specifications. These parts feature board guide features (NPPN062FFKP-RC) or standard configuration (NPPN062FFKS-RC). Header connectors are suitable for applications where the mating interface is provided by a separate receptacle connector. Operating temperature range is -40°C to 105°C.

All parts are MSL 1 rated and suitable for unlimited shelf life storage. Selection should account for connector type requirements (receptacle vs. header), packaging automation compatibility, and thermal operating envelope specifications.

Frequently Asked Questions (FAQ)

Q: Can Amphenol ICC 55510-112LF directly replace Molex 0873811263 in existing designs?

A: Yes. Both are 12-position receptacle connectors with 0.079" (2.00mm) pitch, surface mount solder termination, and push-pull fastening. PCB footprints and mating interface are equivalent. The Amphenol part supports higher voltage (200V vs. 125V) and extended temperature range (-55°C to 125°C vs. -55°C to 105°C), making it suitable for equivalent or more demanding applications.

Q: What is the difference between 55510-112LF and 55510-112TRLF?

A: Both are identical Amphenol ICC Minitek® receptacle connectors with equivalent electrical and mechanical specifications. The difference is packaging: 55510-112LF is supplied in tube format for manual or semi-automated assembly, while 55510-112TRLF is supplied in tape & reel format optimized for automated pick-and-place assembly equipment.

Q: Can Sullins header connectors (NPPN062FFKP-RC or NPPN062FFKS-RC) substitute for the Molex receptacle?

A: Sullins parts are header connectors, not receptacles. They are suitable for applications where the mating interface is provided by a separate receptacle connector. If the design requires a receptacle connector to mate with a header on the opposite board, Sullins headers are not direct substitutes. If the design requires a header connector, these parts maintain equivalent pitch, position count, and mounting specifications.

Q: Are all substitute parts RoHS compliant?

A: Yes. Molex 0873811263 is ROHS3 compliant. Amphenol ICC parts are RoHS compliant. Sullins parts are ROHS3 compliant. All parts meet applicable RoHS requirements for lead-free construction.

Q: What is the MSL rating for these connectors?

A: All listed parts carry MSL 1 (Unlimited) rating, indicating unlimited shelf life without moisture bake-out requirements prior to assembly.

Q: Do operating temperature ranges differ between parts?

A: Yes. Molex 0873811263 and Sullins parts operate from -40°C to 105°C (or -55°C to 105°C for Molex). Amphenol ICC parts support extended range from -55°C to 125°C. Application thermal requirements should determine part selection.
