M7966-05 Equivalent & Substitute Parts

Part Overview

The M7966-05 is a 2-position shunt connector manufactured by Harwin Inc., designed for 0.100" (2.54mm) pitch applications. This closed-top, grip-style connector features gold-plated contacts and is rated for 250V at 3A. The part is currently active in production with full RoHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Substitute parts are identified when equivalent electrical ratings, mechanical compatibility, and connector type specifications are maintained across alternative manufacturers.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the M7966-05 is determined by the following critical parameters:

• Connector Configuration: 2-position (1 x 2) grid layout with 0.100" (2.54mm) pitch spacing
• Connector Type: Closed-top design with grip-style contact retention
• Electrical Performance: Minimum 250V voltage rating and 3A current capacity
• Contact Material: Gold plating for reliable conductivity and corrosion resistance
• Mechanical Compatibility: Female socket gender for standard 0.100" pitch male header pins
• Regulatory Compliance: UL94 V-0 flammability rating and RoHS compliance

The substitute part 880584-1 (TE Connectivity AMP Connectors) meets all critical substitution criteria. While housing material and contact finish thickness differ, these variations remain within acceptable tolerances for equivalent electrical and mechanical function in 2.54mm pitch shunt connector applications.

Parameter Comparison

Engineering Selection Recommendations

Both M7966-05 and 880584-1 are active production parts with equivalent electrical and mechanical specifications for 2.54mm pitch shunt connector applications. Selection between these parts should be based on:

M7966-05 (Harwin Inc.): Select when red color coding is required for circuit identification or when the 0.406" (10.31mm) height is specified in PCB layout constraints.

880584-1 (TE Connectivity AMP Connectors): Select when black color coding is preferred or when the 0.551" (14.00mm) height accommodates board design requirements. This part offers higher contact finish thickness (15.0µin vs. 5.11µin), which may provide extended contact life in high-cycle insertion applications.

Both parts maintain UL94 V-0 flammability compliance and unlimited moisture sensitivity rating (MSL 1), suitable for standard industrial and commercial environments.

Frequently Asked Questions (FAQ)

Q: Can 880584-1 directly replace M7966-05 in existing designs?

A: Electrical and mechanical compatibility is confirmed for standard 2.54mm pitch header applications. Physical height difference (0.406" vs. 0.551") must be evaluated against PCB clearance and stacking requirements. Color difference (red vs. black) affects only visual circuit identification.

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

A: M7966-05 specifies 5.11µin (0.130µm) gold plating, while 880584-1 provides 15.0µin (0.38µm). Both thicknesses meet industry standards for 3A current applications. Thicker plating in 880584-1 may extend contact durability in high-insertion-cycle environments.

Q: Are both parts RoHS compliant?

A: Yes. M7966-05 is ROHS3 Compliant, and 880584-1 is RoHS Compliant. Both meet current regulatory requirements for electronic component manufacturing.

Q: What is the difference between polyester glass-filled and thermoplastic housing materials?

A: M7966-05 uses polyester with glass reinforcement for enhanced mechanical strength and thermal stability. 880584-1 uses thermoplastic housing. Both materials achieve UL94 V-0 flammability rating. Material selection does not affect electrical performance in standard applications.

Q: Is voltage rating specified for 880584-1?

A: Voltage rating is not provided in the 880584-1 specification. M7966-05 is rated for 250V. When voltage rating is a critical design parameter, M7966-05 is the specified choice.

Q: Can these connectors be used interchangeably in production?

A: Yes, provided that physical height, color coding, and housing material differences are acceptable within the application design. Both parts maintain identical electrical ratings (3A current), connector configuration (2-position, 2.54mm pitch), and compliance certifications (UL94 V-0, MSL 1).
