Grayhill 61S100-2-020 Rotary Encoder Optical 100PPR Equivalent & Substitute Parts

Part Overview

The Grayhill 61S100-2-020 is an optical rotary encoder with 100 pulses per revolution (PPR) in quadrature (incremental) output configuration. This vertical-mount encoder operates at 5V supply voltage and features a 1/4" diameter flatted-end actuator with detent positioning. The part is Active status and RoHS Compliant, with unlimited moisture sensitivity rating (MSL 1). Substitute parts are identified when application requirements permit operation at alternative pulse-per-revolution specifications while maintaining compatibility across electrical, mechanical, and environmental parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 61S100-2-020 are grouped based on strict parameter matching across the following critical criteria:

Mandatory Matching Parameters:

• Encoder Type: Optical
• Output Type: Quadrature (Incremental)
• Voltage - Supply: 5V
• Actuator Type: 1/4" Dia Flatted End
• Detent: Yes
• Mounting Type: PCB, Through Hole
• Orientation: Vertical
• Termination Style: PC Pin

Variable Parameter:

• Pulses per Revolution (PPR): Substitutes are available at 16 PPR and 32 PPR specifications. Selection depends on application resolution requirements.

All identified substitutes maintain identical electrical supply voltage, mechanical interface dimensions, mounting configuration, and output signal format. Differences in rotational life specifications (1M cycles for substitutes versus 10M cycles for the main part) reflect design variations across product series but do not preclude substitution when application duty cycles are within substitute part ratings.

Parameter Comparison

Engineering Selection Recommendations

For 32 PPR Resolution Requirement: Select either 62S11-M0-P (Grayhill Inc., Series 62S) or HRPG-AD32#13R (Broadcom Limited, Series HRPG). Both parts are Active status with ROHS3 compliance and REACH Unaffected designation. The 62S11-M0-P offers Grayhill product continuity within the 62S series. The HRPG-AD32#13R provides cross-manufacturer optical encoder technology from Broadcom Limited. Both maintain identical electrical and mechanical specifications to the main part except for PPR and rotational life ratings.

For 16 PPR Resolution Requirement: Select either 62F22-01-P-L (Series 62F) or 62S22-M0-P (Series 62S). Both are Grayhill Inc. products with Active status and ROHS3 compliance. The 62S22-M0-P maintains series consistency within the 62S family. The 62F22-01-P-L represents the 62F series alternative. Both provide identical electrical supply, mechanical interface, and mounting configuration.

Compliance Considerations: All substitute parts maintain REACH Unaffected status and MSL 1 (Unlimited) moisture sensitivity rating, ensuring compatibility with standard storage and handling protocols. ROHS3 compliance across all substitutes exceeds the RoHS Compliant status of the main part, providing enhanced regulatory alignment for new designs.

Rotational Life Assessment: The main part 61S100-2-020 specifies 10M cycle minimum rotational life, while all substitute parts specify 1M cycle minimum. Selection of substitutes requires confirmation that application duty cycles remain within the 1M cycle specification.

Frequently Asked Questions (FAQ)

Q: Can the 62S11-M0-P (32 PPR) directly replace the 61S100-2-020 (100 PPR)?

A: Direct mechanical and electrical replacement is possible. The 62S11-M0-P maintains identical 5V supply voltage, 1/4" flatted-end actuator, detent positioning, PCB through-hole mounting, vertical orientation, and PC pin termination. The primary difference is resolution: 32 PPR versus 100 PPR. Application firmware or signal processing must accommodate the lower resolution output. Rotational life is rated at 1M cycles versus 10M cycles for the main part.

Q: What is the difference between Grayhill and Broadcom optical encoders in this substitution list?

A: Both manufacturers provide optical rotary encoders with identical electrical and mechanical specifications for the substitute parts listed. The HRPG-AD32#13R (Broadcom) and 62S11-M0-P (Grayhill) both deliver 32 PPR quadrature output at 5V with matching actuator and mounting configurations. Selection between manufacturers depends on supply chain availability, existing design qualification, and procurement preferences. Both maintain Active product status and ROHS3 compliance.

Q: Are there PPR options other than 16 and 32 available as substitutes?

A: The provided substitute parts list includes only 16 PPR and 32 PPR alternatives to the 100 PPR main part. No other PPR specifications are documented as substitutes for the 61S100-2-020.

Q: Does the rotational life difference (10M versus 1M cycles) affect substitution suitability?

A: Rotational life specification indicates design cycle rating. The 1M cycle rating of substitute parts is lower than the 10M cycle rating of the main part. Substitution is appropriate when application duty cycles remain within the 1M cycle specification. Applications requiring 10M cycle minimum life should retain the 61S100-2-020 main part.

Q: Are all substitute parts available in the same packaging as the main part?

A: The main part 61S100-2-020 is packaged as "-" (not specified in provided data). All substitute parts are packaged as Bulk. Packaging compatibility should be confirmed with procurement specifications.

Q: What compliance certifications apply to all parts in this substitution group?

A: All parts maintain REACH Unaffected status, MSL 1 (Unlimited) moisture sensitivity rating, and ECCN EAR99 classification. The main part carries RoHS Compliant status; all substitutes carry ROHS3 Compliant status. HTSUS code 8543.70.4500 applies uniformly across all parts.
