Grayhill 62P22-N6 Rotary Encoder Optical 16PPR Equivalent & Substitute Parts

Part Overview

The Grayhill 62P22-N6 is an optical rotary encoder with 16 pulses per revolution (PPR) in quadrature (incremental) output configuration. This vertical-mount encoder features a 3/16" diameter flatted end actuator, integrated switch functionality, and PCB through-hole termination. The product is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system support and component procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the Grayhill 62P22-N6 is determined by strict alignment of the following parameters:

Critical Matching Parameters:

• Encoder Type: Optical (technology platform)
• Output Type: Quadrature (Incremental) (signal protocol)
• Pulses per Revolution: 16 (resolution)
• Voltage - Supply: 5V (power compatibility)
• Orientation: Vertical (mechanical orientation)
• Termination Style: PC Pin (electrical connection)

Allowable Variations:

• Actuator diameter (3/16" vs. 1/4") within mechanical design constraints
• Built-in switch presence (functional addition, not subtraction)
• Mounting type flexibility (PCB through hole and panel mounting both acceptable)
• Rotational life rating (higher values acceptable for extended durability)
• Product status (active status preferred for ongoing availability)

The CUI Devices C14N16N-C3 meets all critical matching parameters while offering enhanced specifications in rotational life (1M cycles vs. 500K cycles) and expanded mounting flexibility.

Engineering Selection Recommendations

Primary Substitute: CUI Devices C14N16N-C3

The C14N16N-C3 is the qualified substitute for the Grayhill 62P22-N6 based on the following engineering criteria:

1. Functional Equivalence: All critical parameters align—optical encoder technology, 16 PPR quadrature output, 5V supply voltage, vertical orientation, and PC pin termination. The encoder will function identically in the target application.

2. Product Status Advantage: The C14N16N-C3 is active production status, ensuring long-term availability and supply chain continuity compared to the obsolete 62P22-N6.

3. Compliance Certification: Both parts maintain RoHS compliance (ROHS3 for the substitute represents current regulatory standards) and unlimited moisture sensitivity rating (MSL 1), meeting environmental and reliability requirements.

4. Enhanced Durability: The C14N16N-C3 provides 1M cycle rotational life versus 500K cycles, offering extended operational longevity.

5. Mechanical Considerations: The 1/4" diameter actuator (versus 3/16") requires verification of shaft coupling compatibility in the mechanical assembly. The substitute's expanded mounting flexibility (panel and PCB through hole) provides installation options.

6. Functional Difference: The C14N16N-C3 does not include a built-in switch. If the integrated switch function is required, alternative substitutes must be evaluated or the switch function must be implemented externally.

Frequently Asked Questions (FAQ)

Q: Can the CUI Devices C14N16N-C3 directly replace the Grayhill 62P22-N6 in my application?

A: The C14N16N-C3 is functionally equivalent for encoder operation (16 PPR, quadrature output, 5V supply, vertical mount, PC pin termination). However, two mechanical considerations require verification: (1) the actuator diameter increases from 3/16" to 1/4", which may affect shaft coupling fit, and (2) the built-in switch is absent on the substitute, requiring external implementation if that function is necessary.

Q: What are the critical parameters that determine substitution compatibility?

A: Substitution compatibility is determined by: encoder type (optical), output format (quadrature incremental), resolution (16 PPR), supply voltage (5V), physical orientation (vertical), and termination style (PC pin). Variations in actuator size, switch presence, mounting flexibility, and rotational life do not prevent substitution but require mechanical and functional assessment.

Q: Why is the CUI Devices part preferred over the obsolete Grayhill part?

A: The C14N16N-C3 is active production status, ensuring component availability for current and future procurement. The Grayhill 62P22-N6 is obsolete, creating supply risk and potential long-term unavailability. Additionally, the substitute offers enhanced rotational life (1M vs. 500K cycles) and current RoHS3 compliance.

Q: Does the 1/4" actuator diameter on the substitute create compatibility issues?

A: The larger actuator diameter must be verified against the mechanical coupling design in your application. If the shaft or coupling is sized for 3/16" diameter, the 1/4" substitute may not fit. Mechanical redesign or alternative coupling solutions may be required.

Q: Is the absence of a built-in switch on the C14N16N-C3 a problem?

A: If your application requires the integrated switch function, the substitute cannot directly replace the main part without external switch implementation. Evaluate whether the switch function is essential or can be provided through alternative circuit design.

Q: Are there packaging or inventory differences between these parts?

A: The Grayhill 62P22-N6 is supplied in standard packaging with 1129 units in stock. The CUI Devices C14N16N-C3 is supplied in box packaging with 1029 units in stock. Both are available as new original components.

Q: What compliance certifications apply to both parts?

A: Both parts are RoHS compliant (Grayhill: RoHS Compliant; CUI: ROHS3 Compliant), meeting environmental regulations. Both have MSL 1 (unlimited moisture sensitivity), indicating robust handling characteristics. Both are classified under ECCN EAR99 and HTSUS 8543.70.4500 for export and tariff purposes.
