Grayhill 62P22-H4 Rotary Encoder Optical 16PPR Equivalent & Substitute Parts

Part Overview

The Grayhill 62P22-H4 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-H4 carries an obsolete product status. 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 Grayhill 62P22-H4 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
• Supply Voltage: 5V
• Detent: Yes
• Built-in Switch: Yes
• Orientation: Vertical

Mechanical Interface Parameters (Allowable Variation):

• Actuator Type: Variation permitted within mechanical compatibility constraints
• Mounting Type: Variation permitted based on PCB layout accommodation
• Termination Style: PC Pin (standard for this category)

Performance & Compliance Parameters:

• Rotational Life: Substitute must meet or exceed minimum specification
• RoHS Status: Substitute must maintain compliance level
• MSL: Substitute must meet or exceed specification
• REACH Status: Substitute must maintain compliance status

The Grayhill 62AG22-H5-P qualifies as a substitute based on matching core functional parameters while presenting controlled variations in mechanical interface characteristics.

Parameter Comparison

Engineering Selection Recommendations

Primary Consideration: Product Status

The 62P22-H4 is classified as obsolete. The 62AG22-H5-P is an active product from the same manufacturer (Grayhill Inc.), ensuring continued availability, technical support, and supply chain reliability for new designs or component replenishment.

Compliance & Certification Advantages

The substitute part 62AG22-H5-P carries ROHS3 compliance, representing an enhanced regulatory position compared to the RoHS Compliant status of the main part. Both parts maintain REACH Unaffected status and MSL Level 1 (Unlimited) moisture sensitivity classification, ensuring equivalent environmental handling requirements.

Performance Enhancement

The 62AG22-H5-P provides rotational life of 1M cycles minimum, exceeding the 500K cycle specification of the 62P22-H4. This represents a 2x improvement in mechanical durability and operational longevity.

Mechanical Interface Considerations

The substitute part differs in two mechanical aspects: actuator diameter (1/4" versus 3/16") and mounting configuration (panel mount versus PCB through-hole). These variations require mechanical design review to confirm accommodation within the target application's physical constraints and mounting infrastructure.

Frequently Asked Questions (FAQ)

Q: Can the 62AG22-H5-P directly replace the 62P22-H4 in existing PCB designs?

A: Functional compatibility is confirmed for all electrical and control parameters. However, mechanical integration requires verification. The substitute features a larger actuator diameter (1/4" versus 3/16") and panel mount configuration versus PCB through-hole mounting. PCB layout and mechanical housing modifications may be necessary.

Q: What are the key functional parameters that make these parts equivalent?

A: Both encoders share identical specifications for encoder type (optical), output type (quadrature incremental), resolution (16 PPR), supply voltage (5V), detent function, built-in switch, vertical orientation, and PC pin termination. These parameters define functional equivalence for signal generation and control interface.

Q: Does the substitute part offer any performance advantages?

A: Yes. The 62AG22-H5-P provides 1M cycle rotational life compared to 500K cycles for the main part, representing a 2x improvement in mechanical durability. Additionally, the substitute carries ROHS3 compliance versus RoHS Compliant status, reflecting enhanced regulatory alignment.

Q: What is the significance of the different mounting types?

A: The 62P22-H4 uses PCB through-hole mounting for direct board integration. The 62AG22-H5-P uses panel mount configuration, requiring installation through a mechanical panel or enclosure. This difference affects mechanical design, housing requirements, and installation methodology but does not impact electrical functionality.

Q: Are there inventory considerations for component selection?

A: The 62P22-H4 shows 1094 pieces in stock (obsolete status). The 62AG22-H5-P shows 715 pieces in stock with active product status. For long-term supply assurance, the active product status of the substitute provides superior availability and production continuity.

Q: Do both parts meet the same environmental and compliance standards?

A: Both parts are RoHS compliant, REACH unaffected, and carry MSL Level 1 (unlimited) moisture sensitivity classification. The substitute achieves ROHS3 compliance, representing an enhanced regulatory position. Environmental handling and storage requirements are equivalent.
