Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0873811264 is determined by the following critical parameters:

• Connector Type & Position Configuration: Receptacle, 12-position, 2-row layout
• Pitch Specification: 0.079" (2.00mm) mating pitch and row spacing
• Mounting & Termination: Surface mount with solder termination
• Fastening Mechanism: Push-pull engagement system
• Contact Interface: Gold-plated mating surface for signal integrity
• Mechanical Compatibility: Board-to-board style with matching insulation height and contact geometry

The identified substitutes meet these core electrical and mechanical requirements. Variations in contact finish thickness, operating temperature range, voltage rating, and packaging format (tube vs. tape & reel) do not preclude functional equivalence when the primary parameters align.

Parameter Comparison

Engineering Selection Recommendations

Amphenol ICC 55510-112LF (Tube Packaging)

This substitute maintains full mechanical and electrical compatibility with the Molex 0873811264. The Minitek® 2.00mm series receptacle matches all critical dimensional and functional parameters. The higher contact finish thickness (30.0µin vs. 15.0µin) and extended operating temperature range (-55°C to 125°C vs. -55°C to 105°C) provide enhanced durability. RoHS compliance is confirmed. Tube packaging is suitable for manual assembly and lower-volume applications.

Amphenol ICC 55510-112TRLF (Tape & Reel Packaging)

This variant is functionally identical to the 55510-112LF but supplied in tape and reel format, optimized for automated pick-and-place assembly. The part includes the "Pick and Place" feature designation. Tape & reel packaging reduces handling time and improves assembly efficiency for high-volume production. All electrical and mechanical specifications remain equivalent to the tube version.

Sullins NPPN062FFKP-RC

This header connector from Sullins Connector Solutions provides mechanical and electrical compatibility with the Molex receptacle. The connector type differs (header vs. receptacle), but the 12-position, 2.00mm pitch configuration and board-to-board style maintain mating compatibility when paired with appropriate complementary connectors. The insulation height is marginally lower (0.173" vs. 0.177"), and the operating temperature range is -40°C to 105°C. ROHS3 compliance is confirmed. The board guide feature provides additional mechanical stability.

Frequently Asked Questions (FAQ)

Q: Can the Amphenol ICC 55510-112LF directly replace the Molex 0873811264 in existing designs?

A: Yes. Both connectors share identical pitch (0.079" / 2.00mm), position count (12), row configuration (2 rows), mounting type (surface mount), and fastening mechanism (push-pull). The mechanical footprint and electrical interface are compatible. The higher voltage rating (200V vs. 125V) and extended temperature range of the Amphenol part provide additional design margin.

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

A: Both parts are electrically and mechanically identical. The primary difference is packaging: 55510-112LF is supplied in tube format for manual handling, while 55510-112TRLF is supplied in tape and reel format for automated assembly. The 55510-112TRLF includes pick-and-place compatibility. Select based on assembly process requirements.

Q: Is the Sullins NPPN062FFKP-RC a true substitute for the Molex receptacle?

A: The Sullins part is a header connector, not a receptacle. It is not a direct pin-for-pin replacement. However, it maintains the same 12-position, 2.00mm pitch board-to-board configuration and can function as a complementary mating component in systems designed for interchangeable connector pairs. Verify mating compatibility with the corresponding receptacle or header in your application.

Q: Are there temperature range limitations when substituting the Molex part?

A: The Molex 0873811264 operates from -55°C to 105°C. The Amphenol substitutes extend to 125°C, providing additional thermal margin. The Sullins part operates to 105°C, matching the Molex specification. For applications requiring operation below -40°C, the Sullins part is not suitable. Verify application temperature requirements before selection.

Q: Do all substitute parts meet RoHS compliance requirements?

A: Yes. The Molex 0873811264 is ROHS3 compliant. The Amphenol ICC parts are RoHS compliant. The Sullins NPPN062FFKP-RC is ROHS3 compliant. All parts meet current RoHS standards for lead-free construction.

Q: What is the significance of contact finish thickness differences?

A: The Molex part specifies 15.0µin (0.38µm) gold plating on mating contacts. The Amphenol substitutes provide 30.0µin (0.76µm), offering thicker gold plating for enhanced wear resistance and contact durability. The Sullins part specifies flash gold plating. Thicker plating extends connector life in high-cycle mating applications but does not affect electrical performance in standard use.

Q: Can I mix packaging formats in production?

A: Tube and tape & reel formats contain identical parts. Mixing formats is acceptable from a functional standpoint but may complicate inventory management and assembly process control. Standardize on a single packaging format per production line for consistency.
