Grayhill Inc. 513375-12-F Rotary Encoder Mechanical 12PPR Equivalent & Substitute Parts

Part Overview

The Grayhill 513375-12-F is an active mechanical rotary encoder with 12 pulses per revolution (PPR) output in BCD (Absolute) format. This vertical-orientation encoder features a 1/8" diameter flatted end actuator, panel and PCB through-hole mounting capability, and PC pin termination. The part is ROHS3 compliant and maintains a rotational life rating of 25,000 cycles minimum. Substitute parts are identified when equivalent mechanical specifications, output characteristics, and compliance certifications align with application requirements, enabling component interchangeability within defined parameter boundaries.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 513375-12-F are identified based on strict alignment of the following critical parameters:

Primary Substitution Criteria:

• Encoder Type: Mechanical
• Output Type: BCD (Absolute)
• Actuator Type: 1/8" Dia Flatted End
• Detent: Yes
• Built-in Switch: No
• Mounting Type: Panel, PCB Through Hole
• Orientation: Vertical
• Termination Style: PC Pin
• Rotational Life: 25K cycles minimum
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)
• REACH Status: REACH Unaffected

Variable Parameter:

• Pulses per Revolution (PPR): Substitutes include 8, 10, 11, and 12 PPR variants

Substitutes are grouped into two categories: Direct Equivalents (12 PPR matching the main part) and Alternative PPR Variants (8, 10, 11 PPR for applications requiring different resolution). All substitute parts maintain identical mechanical, electrical, and compliance specifications except for PPR rating.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalents (12 PPR): Parts 513374-12-C, 513384, and 513385 are direct functional equivalents to 513375-12-F. All three maintain identical specifications across mechanical design, electrical output, mounting configuration, and compliance certifications. Selection among these three parts is determined by inventory availability and lead time requirements. All three parts are active products with ROHS3 compliance and REACH unaffected status.

Alternative Resolution Variants: Parts 513360-10, 513374-11, and 513374-8 provide alternative PPR ratings (10, 11, and 8 respectively) while maintaining all other mechanical and electrical specifications. These variants are suitable for applications requiring different encoder resolution. Selection of alternative PPR ratings must be based on application-specific resolution requirements and signal processing capabilities of the receiving circuit.

Compliance and Product Status: All substitute parts maintain active product status, ROHS3 compliance, REACH unaffected designation, and MSL Level 1 (Unlimited) moisture sensitivity rating. No compliance or regulatory differences exist between the main part and any substitute option.

Frequently Asked Questions (FAQ)

Q: Can 513374-12-C, 513384, or 513385 be used as direct replacements for 513375-12-F? A: Yes. These three parts are direct functional equivalents with identical specifications for encoder type, output format, PPR rating, actuator geometry, mounting configuration, termination style, and compliance certifications. Selection is based on availability and procurement lead time.

Q: What is the difference between the 12 PPR variants (513375-12-F, 513374-12-C, 513384, 513385)? A: All four 12 PPR parts share identical mechanical, electrical, and compliance specifications. Differences exist only in part numbering and base product designation. All are suitable for applications requiring 12 pulses per revolution BCD absolute output.

Q: Can I use a 10 PPR (513360-10) or 8 PPR (513374-8) encoder in place of the 12 PPR 513375-12-F? A: Substitution with alternative PPR ratings is possible only if the application circuit and firmware support the different resolution. The 10 PPR and 8 PPR variants maintain all mechanical and mounting specifications but provide lower encoder resolution. Circuit compatibility must be verified before substitution.

Q: Are all substitute parts ROHS3 compliant? A: Yes. All substitute parts listed (513360-10, 513374-11, 513374-12-C, 513374-8, 513384, 513385) are ROHS3 compliant with REACH unaffected status, matching the compliance profile of 513375-12-F.

Q: What is the rotational life specification for all these encoders? A: All parts, including the main part 513375-12-F and all substitutes, specify a minimum rotational life of 25,000 cycles.

Q: Do these encoders have built-in switches? A: No. All parts in this family, including 513375-12-F and all substitutes, do not include built-in switches. The detent function is mechanical only.

Q: What mounting options are available? A: All parts support both panel mounting and PCB through-hole mounting with vertical orientation and PC pin termination.
