M7680-05 Equivalent & Substitute Parts

Part Overview

The M7680-05 is a 2-position shunt connector with handle manufactured by Harwin Inc., designed for 0.100" (2.54mm) pitch applications. This component features a closed top grip design with female sockets and gold contact finish. The part is classified as obsolete, making identification of suitable substitutes necessary for ongoing design support and procurement planning. Substitute parts must maintain electrical and mechanical compatibility within the M76 series specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution within the M76 series is determined by the following critical parameters that must remain constant:

• Number of positions and grid configuration (2 positions, 1 x 2 arrangement)
• Pitch specification (0.100" / 2.54mm)
• Connector type (Closed Top, Grip)
• Gender (Female Sockets)
• Physical height (0.551" / 14.00mm)
• Electrical ratings (250V, 3A)
• Housing material and flammability rating (Polyester, UL94 V-0)
• Color (Gray)

The M7680-46 qualifies as a direct substitute based on these parameters. The primary difference is the contact finish material: M7680-05 uses gold plating while M7680-46 uses tin plating. Both finishes meet the same electrical and mechanical requirements for this connector category. M7680-46 is currently in active production status with higher inventory availability.

Parameter Comparison

Engineering Selection Recommendations

M7680-46 is the qualified substitute for M7680-05. Both parts maintain identical mechanical dimensions, electrical ratings, and compliance certifications (ROHS3, REACH Unaffected, UL94 V-0). The contact finish difference (gold versus tin) does not affect functional compatibility for standard 2.54mm pitch shunt connector applications. M7680-46 is currently in active production with substantially higher inventory availability (7195 units versus 1041 units), making it the preferred selection for new designs and ongoing procurement. Both parts are suitable for applications requiring 250V, 3A rated connectors in the M76 series.

Frequently Asked Questions (FAQ)

Q: Can M7680-46 be used as a direct replacement for M7680-05?

A: Yes. M7680-46 is a direct substitute. Both parts share identical mechanical dimensions, electrical ratings, housing material, and flammability certification. The contact finish differs (tin versus gold), but this does not affect electrical or mechanical compatibility for standard shunt connector applications.

Q: What is the difference between gold and tin contact finishes?

A: M7680-05 features gold plating at 5.11µin thickness, while M7680-46 uses tin plating at 118.1µin thickness. Both finishes provide adequate electrical conductivity and corrosion resistance for this connector category. Tin plating is standard for cost-effective applications without specific gold-plating requirements.

Q: Why is M7680-05 obsolete?

A: M7680-05 is classified as obsolete by the manufacturer. M7680-46 is the active production equivalent within the M76 series and should be specified for new designs.

Q: Are there packaging differences between these parts?

A: M7680-05 is available in standard packaging, while M7680-46 is supplied in bulk packaging. Both are suitable for component selection; packaging choice depends on procurement volume requirements.

Q: Do both parts meet the same compliance standards?

A: Yes. Both M7680-05 and M7680-46 are ROHS3 compliant, REACH unaffected, and rated UL94 V-0 for material flammability. They meet identical regulatory and safety requirements.

Q: What applications are these connectors suitable for?

A: These 2-position shunt connectors are designed for 0.100" (2.54mm) pitch applications requiring 250V, 3A electrical ratings. They are commonly used in configuration and jumper applications within electronic equipment.
