Grayhill 63R100 Rotary Encoder Optical 100PPR Equivalent & Substitute Parts

Part Overview

The Grayhill 63R100 is an optical rotary encoder with 100 pulses per revolution (PPR), providing quadrature incremental output. This encoder is designed for PCB through-hole mounting in vertical orientation with a 1/4" diameter flatted end actuator. The part is currently active in production status with 729 units in stock.

Substitute parts are identified when alternative models within the same series maintain compatibility across critical electrical and mechanical parameters while offering different resolution specifications. Alternative models may be required due to inventory availability, application-specific resolution requirements, or supply chain considerations.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 63R100 are identified from the Grayhill 63R series based on electrical and mechanical parameter compatibility. The following parameters remain constant across all substitute candidates:

Fixed Parameters (Substitution Basis):

• Encoder Type: Optical
• Output Type: Quadrature (Incremental)
• Voltage - Supply: 5V
• Actuator Type: 1/4" Dia Flatted End
• Detent: No
• Built in Switch: No
• Mounting Type: PCB, Through Hole
• Orientation: Vertical
• Termination Style: PC Pin
• Rotational Life (Cycles Min): 300M
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)
• REACH Status: REACH Unaffected

Variable Parameter (Differentiation):

• Pulses per Revolution: 32, 64, or 100

The 63R100 has three identified substitute parts: 63R32 (32 PPR), 63R64 (64 PPR), and 63RS64 (64 PPR). These parts differ only in resolution specification while maintaining identical electrical characteristics, physical form factor, and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts (63R32, 63R64, 63RS64) maintain active product status and full compliance with ROHS3 and REACH requirements. Selection between the 63R100 and its substitutes is determined solely by the required pulses per revolution specification for the application.

The 63R100 provides 100 PPR resolution. The 63R32 provides 32 PPR resolution with lower granularity. The 63R64 and 63RS64 both provide 64 PPR resolution, representing an intermediate resolution option between the 32 PPR and 100 PPR variants.

All parts share identical electrical supply voltage (5V), mechanical form factor, mounting configuration, and lifecycle specifications. No electrical interface modifications are required when substituting between these models; only the firmware or software interpretation of the quadrature output pulses requires adjustment to account for the different PPR values.

Frequently Asked Questions (FAQ)

Q: Can the 63R32 be used as a direct replacement for the 63R100?

A: The 63R32 is mechanically and electrically compatible with the 63R100 in terms of mounting, voltage supply, and physical form factor. However, the 63R32 provides 32 pulses per revolution compared to the 63R100's 100 pulses per revolution. This difference in resolution requires corresponding changes in application firmware or software to correctly interpret the quadrature output. Direct substitution is possible only if the application can function with lower resolution feedback.

Q: What is the difference between 63R64 and 63RS64?

A: Both the 63R64 and 63RS64 provide identical electrical and mechanical specifications, including 64 pulses per revolution output. The parts are functionally equivalent across all provided parameters. Selection between these two models may be based on inventory availability or specific design documentation requirements.

Q: Are all substitute parts RoHS and REACH compliant?

A: Yes. The 63R100, 63R32, 63R64, and 63RS64 are all ROHS3 compliant and REACH unaffected. All parts meet the same environmental and regulatory compliance standards.

Q: What is the moisture sensitivity level for these encoders?

A: All parts in this group have a Moisture Sensitivity Level (MSL) of 1, which indicates unlimited shelf life without special moisture control requirements during storage or handling.

Q: Can these encoders be used in applications requiring higher rotational life specifications?

A: All substitute parts, including the 63R100, specify a minimum rotational life of 300 million cycles. This specification is consistent across all variants in the 63R series.
