Engineering Selection Recommendations

Primary Recommendation: 2-1445055-2

The substitute part 2-1445055-2 is the direct equivalent for the obsolete 1445055-2. Selection of the substitute part is based on the following engineering criteria:

Product Status: The main part 1445055-2 carries obsolete status, indicating discontinued manufacturing and limited availability. The substitute part 2-1445055-2 maintains active product status, ensuring ongoing availability and supply chain continuity.

Compliance Posture: The substitute part 2-1445055-2 is RoHS Compliant, whereas the main part is RoHS non-compliant. For applications subject to RoHS regulations or customer requirements, the substitute part satisfies current environmental compliance standards.

Functional Equivalence: All critical electrical and mechanical parameters are identical between the main part and substitute. The connector maintains identical pitch, position count, voltage rating, operating temperature range, mounting configuration, and termination method.

Contact Finish Variation: The substitute part features Tin contact finish, whereas the main part specifies Tin-Lead finish. Both finishes maintain identical thickness specifications (100.0µin / 2.54µm) and are functionally compatible for the specified voltage and current applications. The Tin finish in the substitute part aligns with RoHS compliance requirements.

Packaging Consideration: The substitute part is supplied in Tray packaging. Verify packaging requirements for your assembly process and inventory management systems.

Frequently Asked Questions (FAQ)

Q: Can 2-1445055-2 directly replace 1445055-2 in existing designs?

A: Yes. The substitute part 2-1445055-2 is functionally equivalent to 1445055-2 across all critical electrical and mechanical parameters. Identical pitch (3.00mm), position count (2), voltage rating (250V), operating temperature range (-40°C to 105°C), mounting type (through-hole right-angle), and termination method (solder) ensure direct compatibility. No design modifications are required.

Q: What is the difference between Tin-Lead and Tin contact finishes?

A: The main part 1445055-2 specifies Tin-Lead contact finish, while the substitute 2-1445055-2 specifies Tin finish. Both finishes are applied at identical thickness (100.0µin / 2.54µm). The Tin finish in the substitute part complies with RoHS regulations. Both finishes provide equivalent electrical performance and corrosion resistance for the specified 250V, general-purpose applications.

Q: Why is the main part 1445055-2 listed as obsolete?

A: Obsolete status indicates the part has been discontinued by the manufacturer. The substitute part 2-1445055-2 maintains active status, ensuring continued availability and support. For new designs and ongoing production, the active substitute part is the appropriate selection.

Q: Does the packaging difference affect component performance?

A: No. The packaging difference (Tray for the substitute versus unspecified for the main part) affects only handling, storage, and assembly logistics. Component electrical and mechanical performance remains identical regardless of packaging format.

Q: Are there any compliance advantages to using 2-1445055-2?

A: Yes. The substitute part 2-1445055-2 is RoHS Compliant, whereas the main part 1445055-2 is RoHS non-compliant. For applications subject to RoHS directives or customer compliance requirements, the substitute part satisfies current environmental standards. Both parts maintain identical UL94 V-0 flammability ratings and moisture sensitivity levels.

Q: What is the current rating for these connectors?

A: Current rating varies by wire gauge for both the main part and substitute. Consult the connector's wire gauge specifications and mating cable documentation to determine the appropriate current rating for your application.

Q: Can these connectors be used interchangeably with other Micro MATE-N-LOK series components?

A: Both parts belong to the Micro MATE-N-LOK series. Interchangeability with other series components depends on matching pitch (3.00mm), position count (2), and connector type (header). Verify specific component specifications before substitution.
