Grayhill 62P22-H0 Rotary Encoder Optical 16PPR Equivalent & Substitute Parts

Part Overview

The Grayhill 62P22-H0 is an optical rotary encoder with 16 pulses per revolution (PPR) quadrature output, designed for vertical PCB through-hole mounting applications. This component operates at 5V supply voltage and features a 3/16" diameter flatted end actuator with detent positioning and 500K minimum rotational life cycles.

The 62P22-H0 is classified as obsolete. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support legacy system maintenance and upgrades.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 62P22-H0 is determined by strict alignment with the following critical parameters:

Mandatory Matching Parameters:

• Encoder Type: Optical
• Output Type: Quadrature (Incremental)
• Pulses per Revolution: 16 PPR
• Voltage - Supply: 5V
• Termination Style: PC Pin
• Orientation: Vertical

Allowable Variations:

• Actuator Type: Different diameter flatted ends are permissible if mechanical clearance and control interface compatibility are verified in the application
• Mounting Type: Panel mount configurations may substitute for PCB through-hole if the application design accommodates the different mounting interface
• Rotational Life: Substitutes with equal or greater rotational life cycles (≥500K) are acceptable
• Packaging: Bulk or alternative packaging formats do not affect functional compatibility

The substitute part 62AG22-H0-P meets all mandatory matching parameters while introducing variations in actuator diameter (1/4" vs. 3/16"), mounting type (Panel Mount vs. PCB Through Hole), and rotational life (1M vs. 500K cycles).

Engineering Selection Recommendations

Primary Substitute: Grayhill 62AG22-H0-P

The 62AG22-H0-P is the designated substitute for the obsolete 62P22-H0. Both components are manufactured by Grayhill Inc. and share identical core functional specifications: optical encoding technology, 16 PPR quadrature output, 5V operation, vertical orientation, PC pin termination, and detent positioning.

Compliance and Regulatory Status:

• The 62AG22-H0-P holds Active product status, ensuring ongoing availability and manufacturer support
• Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying current regulatory requirements
• Moisture sensitivity level remains at MSL 1 (Unlimited) for both components

Performance Enhancement:

• The substitute part provides 1M rotational life cycles, exceeding the original 500K specification by 100%, offering improved durability for extended-life applications

Integration Considerations:

• Actuator diameter increases from 3/16" to 1/4"; mechanical clearance and shaft coupling compatibility must be verified in the specific application
• Mounting interface changes from PCB through-hole to panel mount; application redesign or adapter solutions may be required depending on the installation method

Inventory and Supply:

• The 62AG22-H0-P maintains active inventory (907 units in stock), providing reliable supply chain access compared to the obsolete 62P22-H0

Frequently Asked Questions (FAQ)

Q: Can the 62AG22-H0-P directly replace the 62P22-H0 without any modifications?

A: Electrical and signal compatibility is direct; however, mechanical integration requires verification. The larger 1/4" actuator diameter and panel mount configuration differ from the original PCB through-hole design. Application-specific mechanical clearance and mounting interface assessment is necessary.

Q: What is the primary reason for substitution?

A: The 62P22-H0 is classified as obsolete. The 62AG22-H0-P is the active equivalent from the same manufacturer, ensuring continued access to functionally compatible optical rotary encoder technology with identical core specifications.

Q: Are the quadrature output signals identical between these two parts?

A: Yes. Both components provide 16 PPR quadrature (incremental) output at 5V supply voltage. Signal format and resolution are functionally equivalent.

Q: Does the increased rotational life of the 62AG22-H0-P affect compatibility?

A: No. The 1M rotational life specification of the substitute exceeds the 500K requirement of the original part. This represents an enhancement and does not create compatibility issues.

Q: What compliance certifications apply to both parts?

A: Both the 62P22-H0 and 62AG22-H0-P are RoHS compliant, REACH unaffected, and carry MSL 1 (Unlimited) moisture sensitivity ratings. Regulatory requirements are satisfied by either component.

Q: How do the packaging formats differ?

A: The 62P22-H0 is specified with "-" packaging notation, while the 62AG22-H0-P is supplied in Bulk packaging. Packaging format does not affect functional performance or electrical compatibility.

Q: What should be verified before implementing the 62AG22-H0-P as a replacement?

A: Verify mechanical clearance for the 1/4" diameter actuator, confirm compatibility with the panel mount interface in the application design, and validate that the control shaft or coupling mechanism accommodates the larger actuator diameter.
