Parameter Comparison

Engineering Selection Recommendations

The 513374-8 functions as a direct equivalent to the 513375-8 based on complete parameter alignment. Both components are manufactured by Grayhill Inc., maintain active product status, and carry identical ROHS3 and REACH compliance certifications. Selection between these parts may be driven by inventory availability, procurement lead times, or supply chain considerations, as no functional or compliance differentiation exists between the two models.

Frequently Asked Questions (FAQ)

Q: Can the 513374-8 replace the 513375-8 in existing designs?

A: Yes. The 513374-8 is a direct functional equivalent. All mechanical, electrical, and operational parameters are identical, including encoder type, output format, PPR rating, actuator geometry, mounting configuration, and compliance certifications.

Q: Are there any differences in rotational life or durability between these parts?

A: No. Both parts specify 25,000 minimum rotational life cycles and are manufactured to identical mechanical standards.

Q: Do these parts require different PCB footprints or mounting procedures?

A: No. Both components feature identical mounting types (Panel, PCB Through Hole), orientation (Vertical), and termination style (PC Pin), ensuring compatibility with the same PCB layouts and assembly procedures.

Q: Are both parts compliant with current environmental regulations?

A: Yes. Both the 513375-8 and 513374-8 are ROHS3 Compliant and REACH Unaffected, meeting current regulatory requirements for electronic component procurement.

Q: What is the difference between the base product numbers 513375 and 513374?

A: The base product numbers identify distinct part families within the Grayhill 51 series. However, the "-8" suffix variants (513375-8 and 513374-8) are functionally equivalent across all specified parameters.

Q: Can I mix these parts in the same production batch?

A: Yes. Since both parts are mechanically and electrically identical, they can be used interchangeably within the same assembly without functional impact or performance variation.
