Molex 0877600417 Rectangular Connector Header - Equivalent & Substitute Parts

Part Overview

The Molex 0877600417 is an active rectangular connector header designed for through-hole, right-angle board-to-board applications. This 4-position, 2-row connector with 0.079" (2.00mm) pitch is widely used in automotive, general purpose, and telecommunications applications. The connector features gold-plated mating contacts and tin-plated posts with phosphor bronze contact material. Finding equivalent substitute parts is necessary to ensure supply chain flexibility, optimize inventory management, and maintain design compatibility across manufacturing batches.

Substitute Part Grouping Explanation

Substitution of the Molex 0877600417 is determined by strict alignment of the following critical parameters:

• Connector Type & Contact Type: Header with male pins
• Position Configuration: 4 positions, 2 rows
• Pitch Specification: 0.079" (2.00mm) mating pitch and row spacing
• Mounting Style: Through-hole, right-angle orientation
• Termination Method: Solder termination
• Fastening Mechanism: Push-pull fastening
• Contact Material & Finish: Phosphor bronze with gold mating surface and tin post finish
• Insulation Material: PCT or equivalent polymer with UL94 V-0 rating
• Compliance Standards: ROHS3 compliant, REACH unaffected

The Harwin Inc. M22-2040205 meets all critical substitution criteria. Both connectors share identical pitch, position count, row configuration, mounting type, and contact material specifications. Both are ROHS3 compliant and carry UL94 V-0 flammability ratings. The M22-2040205 uses polyamide (PA6T) nylon 6T insulation material instead of PCT, which is functionally equivalent for this application category.

Parameter Comparison

Engineering Selection Recommendations

Both the Molex 0877600417 and Harwin M22-2040205 are active products with full ROHS3 compliance and UL94 V-0 material flammability certification. Selection between these parts should be based on:

Molex 0877600417: Use when PCT insulation material is specifically required by design specification or when contact finish thickness specifications (30.0µin mating, 78.7µin post) are critical to the application.

Harwin M22-2040205: Use as a direct substitute when supply constraints affect Molex availability. The M22-2040205 offers cuttable header functionality, providing additional design flexibility. Both connectors maintain identical electrical and mechanical interface specifications for board-to-board connectivity.

Frequently Asked Questions (FAQ)

Q: Can the Harwin M22-2040205 directly replace the Molex 0877600417 in existing designs?

A: Yes. Both connectors share identical pitch (0.079"), position count (4), row configuration (2 rows), mounting type (through-hole right-angle), and contact material (phosphor bronze with gold mating finish). The connectors are mechanically and electrically interchangeable for standard board-to-board applications.

Q: What is the difference in insulation material between these connectors?

A: The Molex 0877600417 uses PCT (polycyclohexylenedimethylene terephthalate) with glass filler, while the Harwin M22-2040205 uses PA6T (polyamide 6T) nylon. Both materials meet UL94 V-0 flammability requirements and are suitable for the same application categories.

Q: Are there packaging differences between these parts?

A: Yes. The Molex 0877600417 is supplied in tray packaging, while the Harwin M22-2040205 is supplied in bulk packaging. This affects inventory management and handling procedures but does not impact electrical or mechanical performance.

Q: Do both connectors meet the same compliance standards?

A: Yes. Both the Molex 0877600417 and Harwin M22-2040205 are ROHS3 compliant, REACH unaffected, and carry UL94 V-0 material flammability ratings. Both have MSL 1 (unlimited) moisture sensitivity levels.

Q: What does "cuttable" mean for the Harwin M22-2040205?

A: The cuttable feature allows the connector header to be cut to custom lengths during assembly, providing design flexibility for applications requiring non-standard position counts. The Molex 0877600417 is a fixed 4-position connector.
