Grayhill 62P22-L4G Rotary Encoder Optical 16PPR - Equivalent & Substitute Parts

Part Overview

The Grayhill 62P22-L4G is an optical rotary encoder with 16 pulses per revolution (PPR) in quadrature (incremental) output configuration. This component operates at 5V supply voltage and features a 3/16" diameter flatted end actuator with vertical orientation and PCB through-hole mounting. The encoder includes integrated detent and built-in switch functionality with PC pin termination.

The 62P22-L4G is classified as obsolete. Identifying equivalent substitute parts is necessary to maintain design continuity, ensure component availability, and support ongoing production or maintenance requirements for systems utilizing this encoder.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 62P22-L4G is evaluated based on the following critical parameters that define functional and mechanical compatibility:

Core Functional Parameters (Must Match):

• Encoder Type: Optical
• Output Type: Quadrature (Incremental)
• Pulses per Revolution: 16 PPR
• Voltage - Supply: 5V
• Detent: Yes
• Built-in Switch: Yes
• Orientation: Vertical

Mechanical Interface Parameters (May Vary Within Limits):

• Actuator Type: 3/16" Dia Flatted End (primary); 1/4" Dia Flatted End (substitute)
• Mounting Type: PCB Through Hole (primary); Panel Mount (substitute)
• Termination Style: PC Pin (common to both)

Performance Parameters (May Exceed Minimum):

• Rotational Life: 500K cycles minimum (primary); 1M cycles (substitute exceeds requirement)

The substitute part 62AG22-L5-P maintains all core functional parameters while introducing differences in mechanical mounting interface and actuator diameter. These differences require mechanical design evaluation for integration into existing assemblies.

Parameter Comparison

Engineering Selection Recommendations

Substitution Feasibility:

The 62AG22-L5-P is a functional equivalent for the 62P22-L4G based on matching core electrical and output specifications. Both encoders are manufactured by Grayhill Inc., operate at 5V, provide 16 PPR quadrature output, and include detent and built-in switch features.

Key Considerations:

1. Mechanical Interface Differences: The substitute part features a 1/4" diameter flatted end actuator compared to the 3/16" diameter of the main part. Mechanical coupling and shaft accommodation must be verified for the target application.

2. Mounting Configuration: The main part is specified for PCB through-hole mounting, while the substitute is panel mount. Integration into existing PCB layouts requires mechanical redesign or adapter solutions.

3. Product Status: The 62AG22-L5-P is active production status, ensuring ongoing availability and supply chain continuity compared to the obsolete 62P22-L4G.

4. Compliance: Both parts meet RoHS requirements. The substitute carries ROHS3 compliance, representing current regulatory alignment.

5. Performance: The substitute encoder exceeds the rotational life specification (1M cycles versus 500K cycles minimum), providing enhanced durability margin.

Selection Basis:

Choose the 62AG22-L5-P when electrical and output functionality are primary requirements and mechanical mounting can be adapted. Verify actuator diameter compatibility and mounting interface feasibility within the target assembly before final selection.

Frequently Asked Questions (FAQ)

Q: Can the 62AG22-L5-P directly replace the 62P22-L4G in existing designs?

A: Electrical and output specifications are compatible. However, mechanical integration requires evaluation. The different actuator diameter (1/4" versus 3/16") and mounting type (panel mount versus PCB through-hole) necessitate mechanical design verification before direct substitution.

Q: What are the critical parameters that must match for substitution?

A: Encoder type (optical), output type (quadrature incremental), pulses per revolution (16 PPR), supply voltage (5V), detent presence, built-in switch presence, and vertical orientation must all match. These parameters define functional compatibility.

Q: Does the 62AG22-L5-P meet the same compliance standards?

A: Both parts are RoHS compliant. The 62AG22-L5-P carries ROHS3 compliance, which represents current regulatory standards. Both parts have MSL 1 (unlimited) moisture sensitivity rating and EAR99 ECCN classification.

Q: What is the significance of the different rotational life specifications?

A: The main part specifies 500K minimum rotational cycles. The substitute provides 1M cycles, exceeding the minimum requirement. This represents improved durability and longer operational life expectancy.

Q: How do the packaging differences affect component handling?

A: The main part uses through-hole PC pin termination for PCB mounting. The substitute uses panel mount configuration with PC pin termination. Packaging differences affect mechanical installation method but not electrical interface or signal compatibility.

Q: Is the 62AG22-L5-P currently available?

A: Yes. The 62AG22-L5-P is active production status with documented inventory availability, ensuring supply chain continuity compared to the obsolete 62P22-L4G.

Q: What mechanical modifications are required for substitution?

A: Mechanical modifications depend on the specific application. The 1/4" diameter actuator requires shaft coupling verification. The panel mount configuration requires mechanical mounting structure adaptation from the original PCB through-hole design.
