Parameter Comparison

Engineering Selection Recommendations

The M7687-05 from Harwin Inc. serves as a direct functional substitute for the obsolete 66971-202. Selection of this substitute is supported by the following engineering factors:

Product Status Consideration: The 66971-202 is classified as obsolete, making the active-status M7687-05 the appropriate choice for ongoing system support and new procurement cycles.

Compliance Alignment: While the original 66971-202 is RoHS non-compliant, the M7687-05 achieves ROHS3 compliance, meeting current regulatory requirements for electronic components in most jurisdictions.

Electrical Specifications: The M7687-05 provides defined electrical ratings (250V, 3A) suitable for standard shunt connector applications, with gold-plated contacts ensuring reliable electrical continuity.

Environmental Compatibility: Both components maintain MSL 1 classification, indicating equivalent moisture tolerance for storage and operational environments.

Export Classification: Both parts retain EAR99 classification, maintaining consistent regulatory treatment in supply chain operations.

Frequently Asked Questions (FAQ)

Q: Can the M7687-05 directly replace the 66971-202 in existing designs?

A: Yes. Both connectors share the same 2-position (1 x 2) configuration and 0.100" (2.54mm) pitch specification, enabling direct mechanical and electrical substitution in standard shunt applications.

Q: What is the primary reason for substitution?

A: The 66971-202 is obsolete, making the active M7687-05 the appropriate replacement for continued component availability and system support.

Q: Are there compliance differences between these parts?

A: Yes. The M7687-05 is ROHS3 compliant, while the 66971-202 is RoHS non-compliant. This difference is significant for new designs or systems requiring current regulatory compliance.

Q: Do both connectors have the same moisture sensitivity rating?

A: Yes. Both components are classified as MSL 1 (Unlimited), indicating equivalent environmental tolerance and storage requirements.

Q: What are the electrical specifications of the substitute part?

A: The M7687-05 is rated for 250V and 3A, with gold-plated contacts providing reliable electrical performance in shunt connector applications.

Q: Is the packaging format compatible?

A: The M7687-05 is supplied in bulk packaging. Verify packaging requirements for your procurement process, as the original 66971-202 packaging format is not specified in available documentation.
