Grayhill 62P22-L0 Rotary Encoder Optical 16PPR Equivalent & Substitute Parts

Part Overview

The Grayhill 62P22-L0 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 62P22-L0 is classified as obsolete product status, necessitating identification of equivalent substitute components for ongoing design requirements and procurement needs. Active alternative models from Grayhill Inc. provide functional equivalency while maintaining core electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete 62P22-L0 is determined by strict equivalency across the following critical parameters:

Electrical Equivalency Requirements:

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

Mechanical Equivalency Requirements:

• Orientation: Vertical
• Detent: Yes
• Built-in Switch: No

Compliance & Environmental Requirements:

• RoHS Compliant
• REACH Unaffected
• Moisture Sensitivity Level: 1 (Unlimited)

The primary substitute, Grayhill 62AG220-L0-P, maintains full electrical and functional equivalency. Differences in actuator diameter (1/4" vs. 3/16"), mounting type (Panel Mount vs. PCB Through Hole), and rotational life rating (1M vs. 500K cycles) represent design variations that may require mechanical integration assessment based on specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

The Grayhill 62AG220-L0-P serves as the primary active substitute for the obsolete 62P22-L0. Both components maintain identical electrical specifications (16 PPR optical quadrature output at 5V) and compliance certifications (RoHS Compliant, REACH Unaffected, MSL 1). The 62AG220-L0-P is currently in active production status with 701 units in stock inventory.

Selection of the 62AG220-L0-P requires mechanical integration verification due to two design differences:

1. Mounting Configuration: The 62AG220-L0-P utilizes panel mount architecture versus the PCB through-hole mounting of the 62P22-L0. This difference necessitates mechanical redesign of the mounting interface.

2. Actuator Diameter: The 62AG220-L0-P features a 1/4" diameter flatted end actuator compared to the 3/16" diameter of the original part. This dimensional change may affect coupling compatibility with existing shaft or control mechanisms.

The 62AG220-L0-P provides enhanced rotational life rating (1M cycles versus 500K cycles), representing improved durability characteristics for extended-life applications.

Frequently Asked Questions (FAQ)

Q: Can the 62AG220-L0-P directly replace the 62P22-L0 without circuit modifications?

A: The electrical interface is fully compatible. Both components provide identical 16 PPR quadrature output at 5V with PC pin termination. No circuit modifications are required. However, mechanical mounting interface redesign is necessary due to the transition from PCB through-hole to panel mount configuration.

Q: What is the significance of the actuator diameter difference (3/16" vs. 1/4")?

A: The actuator diameter affects mechanical coupling to the rotating shaft or control knob. The 1/4" diameter of the 62AG220-L0-P is larger than the 3/16" diameter of the 62P22-L0. Existing mechanical couplings designed for the 3/16" actuator will not accommodate the 1/4" actuator without modification or replacement.

Q: Are there compliance or environmental differences between these parts?

A: No. Both the 62P22-L0 and 62AG220-L0-P carry identical compliance certifications: RoHS Compliant, REACH Unaffected, and Moisture Sensitivity Level 1 (Unlimited). Both components are suitable for equivalent environmental and regulatory applications.

Q: What does the product status difference (Obsolete vs. Active) mean for procurement?

A: The 62P22-L0 is classified as obsolete, indicating discontinued production and limited availability. The 62AG220-L0-P is active production status with current inventory availability (701 units in stock). For new designs or ongoing procurement, the 62AG220-L0-P is the recommended active alternative.

Q: Does the rotational life difference (500K vs. 1M cycles) affect component selection?

A: The 62AG220-L0-P provides double the minimum rotational life specification (1M cycles versus 500K cycles). This represents an enhanced durability characteristic. Selection should be based on application duty cycle requirements. The higher rating of the 62AG220-L0-P provides additional margin for extended-life applications.

Q: What mounting considerations apply when transitioning from PCB through-hole to panel mount?

A: The 62P22-L0 mounts directly to printed circuit boards via through-hole pins. The 62AG220-L0-P requires panel or enclosure mounting with mechanical fastening. The transition requires mechanical redesign of the mounting structure and may involve changes to the control interface layout.
