Molex 0879790406 Equivalent & Substitute Parts

Part Overview

The Molex 0879790406 is a surface mount, right-angle rectangular connector header in the Milli-Grid 87979 series. This 4-position, 2-row connector with 2.00mm pitch is designed for board-to-board or cable applications in automotive, general purpose, and telecommunications environments. The part is currently active and in stock with 870 units available. Alternative components may be required due to inventory constraints, packaging preferences, or specific application requirements such as operating temperature range or contact finish specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the Molex 0879790406 is determined by strict alignment of the following electrical and mechanical parameters:

• Pitch - Mating: 0.079" (2.00mm) — must match exactly for mechanical compatibility
• Number of Positions: 4 — connector capacity must be identical
• Number of Rows: 2 — row configuration must be identical
• Row Spacing - Mating: 0.079" (2.00mm) — must match for proper mating
• Mounting Type: Surface Mount, Right Angle — orientation and assembly method must be preserved
• Contact Type: Male Pin — gender must remain consistent
• Connector Type: Header — functional category must be maintained
• Insulation Height: 0.157" (4.00mm) — physical envelope constraint
• Material Flammability Rating: UL94 V-0 — safety compliance must be met or exceeded

The Amphenol ICC (FCI) 10112690-G03-02ALF meets all mandatory mechanical and electrical parameters. Differences in shrouding design (unshrouded vs. shrouded), contact finish (gold vs. tin), packaging format (tape & reel vs. tray), and operating temperature range are secondary considerations that do not prevent functional substitution when application requirements permit.

Parameter Comparison

Engineering Selection Recommendations

Both the Molex 0879790406 and Amphenol ICC 10112690-G03-02ALF are active products with UL94 V-0 flammability ratings and unlimited moisture sensitivity levels. Selection between these parts should be based on the following criteria:

Molex 0879790406 is the primary choice when shrouded connector design is required for mechanical protection or when tin contact finish is specified in the application design.

Amphenol ICC 10112690-G03-02ALF is suitable as a substitute when the application permits unshrouded design, when gold contact finish is preferred for enhanced corrosion resistance, or when tape & reel packaging is required for automated assembly processes. The specified operating temperature range of -55°C to 125°C and current rating of 3A at 200V provide additional performance data for applications requiring these parameters.

Both parts comply with RoHS and REACH regulations as applicable to their respective manufacturing standards. The choice between them does not compromise electrical or mechanical function when application constraints are satisfied.

Frequently Asked Questions (FAQ)

Q: Can the Amphenol ICC 10112690-G03-02ALF be used as a direct replacement for the Molex 0879790406?

A: Yes, for applications where unshrouded connector design is acceptable. Both parts share identical pitch (2.00mm), position count (4), row configuration (2), and mounting type (surface mount, right angle). The primary difference is shrouding design. Verify that your PCB layout and mating connector accommodate the unshrouded profile.

Q: What is the impact of the different contact finishes?

A: The Molex part uses tin finish at 100.0µin thickness, while the Amphenol part uses gold finish at 30.0µin thickness. Gold provides superior corrosion resistance in harsh environments. Tin is suitable for standard applications. Contact finish selection should align with environmental exposure and expected connector cycle life.

Q: Does the packaging difference affect compatibility?

A: No. The Molex part is supplied in tray packaging, while the Amphenol part is supplied in tape & reel format. Packaging affects only the assembly process and handling. The connector itself functions identically regardless of packaging format.

Q: Are both parts compliant with automotive and telecommunications standards?

A: Both parts meet UL94 V-0 flammability requirements and RoHS compliance standards. The Molex part is listed for automotive, general purpose, and telecommunications applications. The Amphenol part is active and compliant with applicable regulations. Verify specific application certifications with your design requirements.

Q: What should I consider when switching from the Molex to the Amphenol part?

A: Confirm that your mating connector is compatible with the unshrouded design. Verify that the gold contact finish does not conflict with your soldering or assembly process. Confirm that tape & reel packaging is compatible with your production equipment if applicable.
