Engineering Selection Recommendations

The 1-1546220-0 is classified as obsolete and carries undefined RoHS and REACH compliance status. For new designs and ongoing production, the substitute parts 1-1546074-0 and 1-282847-0 are recommended based on the following factors:

1-1546074-0 is the primary substitute. It maintains active product status with full ROHS3 compliance and REACH affected designation. This part is suitable for applications requiring regulatory compliance documentation and long-term supply chain stability.

1-282847-0 is an alternative substitute with identical electrical and mechanical specifications. It also carries active product status and ROHS3 compliance. This part provides an additional sourcing option with equivalent performance characteristics.

Both substitute parts are functionally interchangeable with the 1-1546220-0 across all electrical parameters, mechanical dimensions, and mounting requirements. The selection between 1-1546074-0 and 1-282847-0 depends on color preference, packaging requirements, and supplier availability, as these are the only differentiating factors.

Frequently Asked Questions (FAQ)

Q: Can 1-1546074-0 or 1-282847-0 be used as direct replacements for 1-1546220-0 in existing designs?

A: Yes. Both substitute parts are electrically and mechanically identical to the 1-1546220-0. They feature the same 10-position configuration, 5.08mm pitch, 35° mating angle, current and voltage ratings, wire gauge compatibility, and screw termination specifications. PCB footprints and mounting hole patterns are identical.

Q: What is the difference between the three parts?

A: The 1-1546220-0, 1-1546074-0, and 1-282847-0 differ only in housing color (gray, black, and green respectively) and product status/compliance certifications. The 1-1546220-0 is obsolete with undefined compliance status. The 1-1546074-0 and 1-282847-0 are active products with ROHS3 compliance and REACH affected designation.

Q: Why is the 1-1546220-0 marked as obsolete?

A: The 1-1546220-0 has been superseded by newer variants in the Buchanan series. The substitute parts 1-1546074-0 and 1-282847-0 represent the current production equivalents with improved compliance certifications.

Q: Are there any performance differences between the substitute parts?

A: No. All three parts deliver identical electrical performance, current capacity, voltage rating, temperature range, and mechanical reliability. The only differences are cosmetic (housing color) and administrative (product status and compliance certifications).
