Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity 1-770971-1 is a direct substitute for the 770971-2 across all electrical and mechanical parameters. The following factors support this substitution:

Product Status: The 770971-2 is classified as obsolete, while the 1-770971-1 maintains active product status. This ensures ongoing availability and manufacturer support for new designs and production continuity.

Compliance Characteristics: The 1-770971-1 is RoHS compliant, whereas the 770971-2 is RoHS non-compliant. For applications subject to RoHS regulations or requiring compliance with modern environmental standards, the 1-770971-1 is the appropriate selection.

Contact Finish Specification: The 770971-2 specifies Tin-Lead post finish, while the 1-770971-1 specifies Tin post finish. Both maintain identical contact finish thickness (150.0µin / 3.81µm) and identical mating contact finish (Gold, 30.0µin / 0.76µm). The Tin post finish of the 1-770971-1 aligns with lead-free manufacturing practices.

Electrical and Mechanical Equivalence: All critical parameters including connector type, contact configuration, pitch, row spacing, mounting style, shrouding, termination method, voltage rating, operating temperature range, and flammability rating are identical between the two parts.

Inventory Availability: The 1-770971-1 is available in higher inventory quantities (1620 Pcs) compared to the 770971-2 (963 Pcs), supporting supply chain reliability.

Frequently Asked Questions (FAQ)

Q: Can the 1-770971-1 be used as a direct replacement for the 770971-2 in existing designs?

A: Yes. The 1-770971-1 is electrically and mechanically equivalent to the 770971-2 across all critical parameters including connector type, contact configuration, pitch, row spacing, mounting style, and electrical ratings. Both parts are from the same Mini-Universal MATE-N-LOK series and maintain identical form factor and interface specifications.

Q: What is the difference between the Tin-Lead finish on the 770971-2 and the Tin finish on the 1-770971-1?

A: Both finishes maintain identical contact finish thickness (150.0µin / 3.81µm) on the post. The Tin finish on the 1-770971-1 represents a lead-free alternative that complies with modern manufacturing standards and RoHS regulations. The mating contact finish (Gold) is identical on both parts.

Q: Why is the 770971-2 listed as obsolete?

A: The 770971-2 has been superseded by the 1-770971-1, which offers active product status, RoHS compliance, and lead-free contact finish specifications. The 1-770971-1 provides equivalent functionality with improved compliance characteristics.

Q: Are there any packaging differences between the 770971-2 and 1-770971-1?

A: The 770971-2 packaging is listed as unspecified, while the 1-770971-1 is packaged in Bulk. Both parts are identical in form factor and electrical specifications. Packaging differences do not affect functional compatibility.

Q: What is the operating temperature range for both parts?

A: Both the 770971-2 and 1-770971-1 operate across the identical temperature range of -20°C to 105°C, supporting applications across standard industrial and commercial environments.

Q: Are both parts rated for the same voltage?

A: Yes. Both the 770971-2 and 1-770971-1 are rated for 600VAC, providing equivalent electrical performance and safety margins for general-purpose applications.

Q: What is the moisture sensitivity level for these connectors?

A: Both parts carry a Moisture Sensitivity Level (MSL) of 1, indicating unlimited shelf life without special moisture control requirements during storage and handling.

Q: Can these connectors be used interchangeably in new production?

A: The 1-770971-1 is the recommended selection for new production due to its active product status, RoHS compliance, and lead-free specifications. The 770971-2 should be reserved for maintenance and repair of existing systems where the original part specification is required.
