Equivalent & Substitute Parts for Molex 0872631623

Part Overview

The Molex 0872631623 is a 16-position rectangular receptacle connector with 0.079" (2.00mm) pitch, designed for surface mount applications in board-to-board or cable interconnect scenarios. This connector features bottom entry configuration, gold-plated mating contacts, and push-pull fastening. The part is active in production with 817 units currently in stock.

Substitute parts are identified when equivalent electrical performance and mechanical compatibility can be maintained across the same connector category, pitch, position count, and mounting technology. Alternative sources provide equivalent or enhanced specifications for applications requiring extended availability or alternative entry configurations.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the Molex 0872631623 are qualified based on the following critical parameters that determine functional and mechanical interchangeability:

• Connector Position Count: 16 positions (all substitutes maintain this requirement)
• Pitch Specification: 0.079" (2.00mm) mating pitch and row spacing
• Mounting Technology: Surface mount solder termination
• Contact Configuration: Female socket contacts with gold mating finish
• Fastening Mechanism: Push-pull connector system
• Electrical Performance: Minimum 1A current rating and compatible voltage specifications
• Environmental Compliance: UL94 V-0 flammability rating and RoHS compliance

The 3M 153216-2020-RB-WB and Sullins NPPN082GFNS-RC connectors satisfy these core substitution criteria while offering variations in entry configuration (bottom or top entry), contact finish thickness, and insulation material composition.

Parameter Comparison

Engineering Selection Recommendations

All three connectors maintain active production status and meet UL94 V-0 flammability requirements with RoHS compliance. Selection between these parts is determined by specific application requirements and mechanical constraints.

The Molex 0872631623 provides the baseline specification with bottom entry configuration and standard gold contact finish thickness. This part is suitable for applications with established design requirements and immediate availability needs.

The 3M 153216-2020-RB-WB offers enhanced voltage rating (500VDC versus 125VAC) and increased contact finish thickness (30.0µin), with the flexibility of bottom or top entry configuration. The higher insulation height (0.129" versus 0.110") must be evaluated for PCB layout compatibility. Tape & Reel packaging supports automated assembly processes.

The Sullins NPPN082GFNS-RC provides the highest current rating (2A) and maintains the original insulation height specification. The header connector type with top or bottom entry flexibility accommodates alternative board-to-board mounting orientations. Operating temperature range extends to -40°C minimum, which is acceptable for most commercial and industrial applications. Contact finish is specified as flash gold on both mating and post surfaces.

Frequently Asked Questions (FAQ)

Q: Can the 3M 153216-2020-RB-WB be used as a direct replacement for the Molex 0872631623?

A: The 3M part maintains electrical and mechanical compatibility across pitch, position count, mounting type, and fastening mechanism. The increased insulation height (0.129" versus 0.110") requires verification against PCB layout constraints. The enhanced voltage rating (500VDC) and contact finish thickness provide equivalent or superior performance for the specified 125VAC application.

Q: What is the difference between receptacle and header connector types in this comparison?

A: The Molex and 3M parts are receptacles designed to accept mating plugs. The Sullins part is a header connector that typically mates with receptacle connectors. Both connector types maintain the same 0.079" pitch and 16-position configuration. Selection depends on whether the application requires a receptacle or header interface.

Q: Are there entry configuration differences that affect compatibility?

A: The Molex part specifies bottom entry only. The 3M part offers bottom or top entry flexibility. The Sullins part offers top or bottom entry flexibility. Entry configuration affects the mating plug approach angle and PCB routing requirements. Verify that the selected entry configuration aligns with the mating connector and board layout design.

Q: How do contact finish thickness specifications impact connector performance?

A: Contact finish thickness affects durability and mating cycle life. The Molex part specifies 15.0µin (0.38µm) mating finish. The 3M part specifies 30.0µin (0.76µm), providing increased wear resistance. The Sullins part specifies flash gold, which is a minimal coating. For applications with frequent mating cycles, thicker finishes provide extended service life.

Q: What packaging considerations apply to these connectors?

A: The Molex and Sullins parts are supplied in tube packaging, suitable for manual assembly and lower-volume applications. The 3M part is supplied in Tape & Reel format, optimized for automated pick-and-place assembly processes. Packaging selection depends on production volume and assembly methodology.

Q: Are all three parts suitable for automotive applications?

A: The Molex 0872631623 explicitly lists automotive applications. The 3M and Sullins parts do not specify automotive applications in the provided data. Automotive qualification typically requires additional testing and certification beyond standard RoHS compliance. Verify automotive suitability with the manufacturer if this application requirement exists.
