Grayhill 62P22-N4 Rotary Encoder Optical 16PPR Equivalent & Substitute Parts

Part Overview

The Grayhill 62P22-N4 is an optical rotary encoder with 16 pulses per revolution (PPR) in quadrature (incremental) output configuration. This vertical-mounted encoder features a 3/16" diameter flatted end actuator, integrated switch functionality, and PCB through-hole termination. The part is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system support and component procurement.

Substitute parts must maintain electrical compatibility (5V supply, quadrature output, 16 PPR) and mechanical compatibility (vertical orientation, PC pin termination, through-hole mounting capability) to ensure direct functional replacement without circuit redesign.

Substitute Part Grouping Explanation

Substitute parts for the Grayhill 62P22-N4 must satisfy the following criteria based on allowed electrical and mechanical parameters:

Electrical Compatibility Requirements:

  • Encoder type: Optical
  • Output configuration: Quadrature (Incremental)
  • Resolution: 16 PPR
  • Supply voltage: 5V

Mechanical Compatibility Requirements:

  • Orientation: Vertical
  • Mounting capability: PCB through-hole
  • Termination: PC pin
  • Actuator interface: Flatted end design

Performance & Compliance Requirements:

  • Rotational life minimum: 500K cycles or greater
  • RoHS compliance status: RoHS Compliant or ROHS3 Compliant
  • Moisture sensitivity: MSL 1 (Unlimited)

The CUI Devices C14N16N-C3 meets all critical electrical and mechanical compatibility parameters. Variations in actuator diameter (1/4" vs. 3/16"), built-in switch presence, and rotational life rating represent design differences that do not prevent functional substitution when mechanical envelope and switch functionality are evaluated against application requirements.

Engineering Selection Recommendations

Primary Substitute: CUI Devices C14N16N-C3

The CUI Devices C14N16N-C3 is the qualified substitute for the obsolete Grayhill 62P22-N4 based on the following engineering factors:

Electrical Compatibility: Both encoders operate at 5V supply voltage, generate 16 PPR quadrature (incremental) output signals, and utilize optical sensing technology. Signal compatibility is established for direct circuit integration.

Mechanical Compatibility: Both parts feature vertical orientation, PC pin termination, and PCB through-hole mounting capability. The C14N16N-C3 additionally supports panel mounting, providing installation flexibility.

Product Status & Availability: The Grayhill 62P22-N4 is classified as obsolete with limited remaining inventory (647 units). The CUI Devices C14N16N-C3 maintains active product status with higher inventory availability (1029 units), ensuring long-term procurement viability.

Compliance & Certifications: Both parts meet RoHS compliance requirements (RoHS Compliant vs. ROHS3 Compliant), share identical ECCN and HTSUS classifications, and maintain MSL 1 (Unlimited) moisture sensitivity ratings.

Performance Considerations: The C14N16N-C3 provides superior rotational life specification (1M cycles vs. 500K cycles), exceeding the original part's durability rating.

Design Differences Requiring Evaluation:

  • Actuator Diameter: The C14N16N-C3 features a 1/4" diameter flatted end actuator compared to the 62P22-N4's 3/16" diameter. Mechanical coupling compatibility must be verified against the application's shaft or coupling interface.

  • Built-in Switch: The 62P22-N4 includes an integrated switch function; the C14N16N-C3 does not. Applications requiring switch functionality must implement external switching logic or select an alternative encoder model with integrated switch capability.

Frequently Asked Questions (FAQ)

Q: Can the CUI Devices C14N16N-C3 directly replace the Grayhill 62P22-N4 in existing PCB assemblies?

A: Electrical and signal compatibility is established. However, mechanical compatibility depends on two factors: (1) the actuator shaft diameter interface (1/4" vs. 3/16"), and (2) whether the application circuit requires the built-in switch function. PCB through-hole mounting and PC pin termination are identical, allowing direct socket replacement if mechanical and functional requirements are satisfied.

Q: What is the significance of the different actuator diameters?

A: The actuator diameter determines the mechanical coupling interface with the application's rotating shaft or coupling mechanism. The C14N16N-C3's 1/4" diameter is larger than the 62P22-N4's 3/16" diameter. Compatibility depends on the specific shaft or coupling design in the application. Mechanical verification is required before substitution.

Q: The C14N16N-C3 does not include a built-in switch. How does this affect substitution?

A: The Grayhill 62P22-N4 integrates a switch function within the encoder housing. The CUI Devices C14N16N-C3 provides only quadrature output without integrated switching. If the application circuit relies on the switch function, external switching logic must be implemented, or an alternative encoder model with integrated switch capability must be selected.

Q: Are both parts RoHS compliant?

A: Yes. The Grayhill 62P22-N4 is RoHS Compliant, and the CUI Devices C14N16N-C3 is ROHS3 Compliant. Both meet RoHS environmental compliance requirements. ROHS3 represents an updated compliance standard and is acceptable for applications requiring RoHS certification.

Q: What is the difference in rotational life specifications?

A: The Grayhill 62P22-N4 specifies a minimum rotational life of 500K cycles. The CUI Devices C14N16N-C3 specifies 1M cycles (1,000,000 cycles). The C14N16N-C3 provides double the rotational life rating, indicating superior mechanical durability and extended operational lifespan.

Q: Why is the Grayhill 62P22-N4 classified as obsolete?

A: Product obsolescence indicates that the manufacturer has discontinued production and support for this model. Remaining inventory is limited (647 units). Substitution with an active product (CUI Devices C14N16N-C3) ensures long-term availability and ongoing manufacturer support.

Q: Are the packaging formats compatible?

A: The Grayhill 62P22-N4 is packaged as individual units (packaging not specified). The CUI Devices C14N16N-C3 is packaged in boxes. Both are suitable for PCB assembly integration. Packaging format does not affect electrical or mechanical compatibility.

Q: What mounting options does each encoder support?

A: The Grayhill 62P22-N4 supports PCB through-hole mounting only. The CUI Devices C14N16N-C3 supports both panel and PCB through-hole mounting, providing additional installation flexibility for applications requiring panel-mounted encoder configurations.

Q: Are the ECCN and HTSUS classifications identical?

A: Yes. Both the Grayhill 62P22-N4 and CUI Devices C14N16N-C3 share identical ECCN (EAR99) and HTSUS (8543.70.4500) classifications. Export control and tariff classifications are equivalent, simplifying regulatory and procurement documentation.
