Grayhill Inc. 513375-10 Rotary Encoder Mechanical 10PPR Equivalent & Substitute Parts

Part Overview

The Grayhill Inc. 513375-10 is an active mechanical rotary encoder with 10 pulses per revolution (PPR) output in BCD (Absolute) format. This vertical-orientation encoder features a 1/8" diameter flatted end actuator and is designed for panel and PCB through-hole mounting applications. The part is ROHS3 compliant and maintains a rotational life rating of 25,000 cycles minimum. Substitute parts may be required due to inventory constraints, application-specific PPR requirements, or supply chain considerations while maintaining functional compatibility within the Series 51 product line.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility within the Grayhill Series 51 mechanical rotary encoder line is determined by the following critical parameters:

Primary Compatibility Criteria:

• Encoder Type: Mechanical
• Output Type: BCD (Absolute)
• Actuator Type: 1/8" Dia Flatted End
• Mounting Type: Panel, PCB Through Hole
• Orientation: Vertical
• Termination Style: PC Pin
• Detent: Yes
• Rotational Life: 25K cycles minimum

Variable Parameter:

• Pulses per Revolution (PPR): May differ based on application requirements

Parts meeting all primary criteria are classified as direct substitutes. The 513360-10 maintains identical specifications to the 513375-10, including 10 PPR output. The 513374-8 differs only in PPR specification (8 PPR versus 10 PPR) and is applicable where the application circuit supports 8-position absolute encoding instead of 10-position encoding.

Parameter Comparison

Engineering Selection Recommendations

513360-10 Substitution: The 513360-10 is a direct functional equivalent to the 513375-10. Both parts share identical electrical and mechanical specifications, including 10 PPR BCD absolute output, vertical orientation, and PC pin termination. Both maintain active product status and full ROHS3 compliance. Selection between these two parts is based on inventory availability and supply chain logistics rather than technical performance differences.

513374-8 Substitution: The 513374-8 is applicable only when the application circuit is designed to accept 8-position absolute encoding. This part maintains all mechanical and compliance characteristics of the 513375-10 but outputs 8 PPR instead of 10 PPR. This substitution requires confirmation that the receiving circuit supports 8-bit BCD encoding. The 513374-8 is active and ROHS3 compliant, meeting all regulatory requirements.

All three parts are manufactured by Grayhill Inc., maintain Series 51 specifications, and carry identical compliance certifications (ROHS3, REACH Unaffected, MSL 1). Selection should be based on PPR requirement compatibility and current inventory status.

Frequently Asked Questions (FAQ)

Q: Can the 513360-10 be used as a direct replacement for the 513375-10? A: Yes. The 513360-10 and 513375-10 share identical specifications across all electrical and mechanical parameters. Both provide 10 PPR BCD absolute output with vertical orientation and PC pin termination. Substitution is functionally transparent.

Q: Under what conditions can the 513374-8 substitute for the 513375-10? A: The 513374-8 can substitute only when the application circuit is designed to process 8-position absolute encoding. The critical difference is PPR specification: 513374-8 outputs 8 PPR while 513375-10 outputs 10 PPR. All other mechanical and electrical characteristics remain identical. Circuit compatibility with 8-bit BCD encoding must be confirmed before substitution.

Q: Are there packaging or inventory differences between these parts? A: All three parts are supplied in bulk packaging. Current inventory levels are: 513375-10 (1002 pcs), 513360-10 (852 pcs), and 513374-8 (904 pcs). Packaging format is consistent across all variants.

Q: Do all three parts meet the same compliance standards? A: Yes. All three parts are ROHS3 compliant, REACH unaffected, and carry MSL 1 (unlimited moisture sensitivity level). Compliance certifications are identical across 513375-10, 513360-10, and 513374-8.

Q: What is the primary technical difference between the substitute parts? A: The 513360-10 is functionally identical to the 513375-10. The 513374-8 differs only in PPR specification (8 versus 10). All other parameters—encoder type, output type, actuator geometry, mounting configuration, orientation, termination style, rotational life, and compliance status—are identical across all three parts.

Q: Can these encoders be used interchangeably in panel and PCB through-hole applications? A: Yes, all three parts support both panel and PCB through-hole mounting with identical mechanical interfaces. The 1/8" diameter flatted end actuator and PC pin termination are consistent across all variants.
