The primary distinction between these parts is the contact shape: 640383-7 features square contacts, while 640384-7 features circular contacts. Both parts maintain identical electrical and mechanical specifications across all other parameters, enabling direct substitution in applications where contact geometry does not impose design constraints.

Parameter Comparison

Engineering Selection Recommendations

Both the TE Connectivity 640383-7 and 640384-7 maintain active product status and are fully compliant with RoHS regulations and UL94 V-0 flammability standards. The 640383-7 carries RoHS Compliant certification, while the 640384-7 carries ROHS3 Compliant certification, both meeting current environmental and safety requirements.

Selection between these parts is determined by contact geometry requirements. The 640383-7 with square contacts and the 640384-7 with circular contacts are electrically and mechanically equivalent across all specified parameters. The choice between square and circular contact geometry depends on mating connector specifications and application-specific mechanical requirements.

Both parts are rated for identical operating conditions: -55°C to 105°C temperature range, 600VAC voltage rating, and UL94 V-0 flammability classification. Both feature tin-plated copper alloy contacts with thermoplastic, glass-filled insulation and unlimited moisture sensitivity rating (MSL 1).

Frequently Asked Questions (FAQ)

Q: Can the 640383-7 and 640384-7 be used interchangeably?

A: These parts are electrically and mechanically equivalent with one exception: contact shape. The 640383-7 features square contacts while the 640384-7 features circular contacts. Interchangeability depends on whether the mating connector is designed to accept the specific contact geometry. Verify mating connector specifications before substitution.
