Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 513361-12-F is determined by the following critical parameters:

Primary Substitution Criteria (Must Match):

• Manufacturer: Grayhill Inc.
• Series: 51
• 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
• Product Status: Active

Variable Parameter (Substitution Allowed):

• Pulses per Revolution: 12PPR (primary), 8PPR, 10PPR, 11PPR (alternatives)

Secondary Consideration:

• Packaging: Bulk (substitute parts) vs. standard (main part)
• RoHS Compliance: RoHS3 Compliant (substitutes) vs. RoHS Compliant (main part)

Substitute parts 513360-10, 513374-8, 513374-11, 513374-12-C, 513384, and 513385 maintain all critical mechanical and electrical parameters. Variations in PPR accommodate applications requiring different resolution levels. All substitutes are Series 51 mechanical encoders with identical mounting, termination, and operational characteristics.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalents (12PPR): Parts 513374-12-C, 513384, and 513385 are direct functional equivalents to 513361-12-F. All three maintain 12 pulses per revolution output with identical mechanical and electrical specifications. Selection among these three is determined by packaging requirements and inventory availability. All three substitute parts carry ROHS3 Compliant certification, which supersedes the RoHS Compliant status of the main part. All parts maintain active product status and unlimited moisture sensitivity rating.

Alternative Resolution Options (8PPR, 10PPR, 11PPR): Parts 513360-10, 513374-8, and 513374-11 provide alternative pulse-per-revolution configurations within the Series 51 mechanical encoder family. These parts are substitutable only when application requirements permit different encoder resolution. All mechanical and mounting characteristics remain identical to the main part. Selection of alternative PPR values requires confirmation that the application circuit and firmware support the different resolution output.

Compliance and Regulatory Alignment: All substitute parts maintain REACH Unaffected status, EAR99 export classification, and HTSUS code 8543.70.4500 alignment with the main part. The upgrade to ROHS3 Compliant status on substitute parts represents enhanced regulatory compliance. Moisture sensitivity level remains at MSL 1 (Unlimited) across all parts, indicating no special storage or handling requirements.

Packaging Consideration: The main part 513361-12-F is supplied in standard packaging, while all substitute parts are supplied in bulk packaging. Bulk packaging does not affect component functionality or performance characteristics.

Frequently Asked Questions (FAQ)

Q: Can 513374-12-C, 513384, or 513385 be used as direct replacements for 513361-12-F?

A: Yes. These three parts are direct functional equivalents. All maintain 12 pulses per revolution, identical mechanical specifications, vertical orientation, PC pin termination, and 25K rotational life. The only differences are packaging format (bulk vs. standard) and RoHS certification level (ROHS3 vs. RoHS Compliant). No circuit or firmware modifications are required.

Q: What is the difference between the 12PPR and alternative PPR options?

A: The main part and direct equivalents (513374-12-C, 513384, 513385) output 12 pulses per revolution. Alternative options provide 8PPR (513374-8), 10PPR (513360-10), or 11PPR (513374-11). The PPR value determines encoder resolution. Selection of alternative PPR requires application-level confirmation that the receiving circuit and firmware support the different resolution output. All other mechanical and electrical parameters remain identical.

Q: Are there any compatibility issues between the main part and substitute parts?

A: No compatibility issues exist for direct 12PPR equivalents (513374-12-C, 513384, 513385). All maintain identical mounting type (Panel, PCB Through Hole), orientation (Vertical), actuator type (1/8" Dia Flatted End), termination style (PC Pin), and detent mechanism. Alternative PPR parts (8, 10, 11) are mechanically and electrically compatible but require application-level verification of resolution support.

Q: What does the bulk packaging difference mean?

A: Bulk packaging indicates the substitute parts are supplied without individual packaging materials. This does not affect component performance, functionality, or electrical characteristics. Bulk packaging is standard for high-volume applications and inventory management.

Q: Are all parts RoHS compliant?

A: Yes. The main part 513361-12-F carries RoHS Compliant certification. All substitute parts carry ROHS3 Compliant certification, which represents an enhanced compliance standard. Both certifications satisfy RoHS requirements. ROHS3 Compliant status on substitute parts indicates updated regulatory alignment.

Q: Can I substitute a lower PPR encoder for a 12PPR application?

A: Substitution of alternative PPR values (8, 10, or 11) requires application-level verification. The receiving circuit and firmware must support the different encoder resolution. Mechanical and mounting compatibility is confirmed, but functional compatibility depends on application design parameters.

Q: What is the rotational life specification?

A: All parts, including the main part and all substitutes, specify a minimum rotational life of 25,000 cycles. This specification applies to mechanical encoder operation under normal conditions.

Q: Are there any supply chain or lead time advantages to using substitute parts?

A: Inventory levels vary across the part family. Current stock levels are: 513361-12-F (867 units), 513360-10 (852 units), 513374-8 (904 units), 513374-11 (1035 units), 513374-12-C (886 units), 513384 (893 units), and 513385 (849 units). Part selection may be influenced by current inventory availability for specific applications.
