Grayhill 62P22-N0 Rotary Encoder Optical 16PPR Equivalent & Substitute Parts

Part Overview

The Grayhill 62P22-N0 is an optical rotary encoder with 16 pulses per revolution (PPR) in quadrature (incremental) output configuration. This encoder is designed for vertical PCB through-hole mounting applications requiring precise rotational position feedback. The product is currently obsolete, making identification of functionally equivalent alternatives essential for ongoing system support, maintenance, and new design implementations where legacy component replacement is necessary.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the Grayhill 62P22-N0 is determined by strict equivalence across the following critical parameters:

Critical Matching Parameters:

• Encoder Type: Optical (technology platform)
• Output Type: Quadrature (Incremental) (signal protocol)
• Pulses per Revolution: 16 (resolution specification)
• Voltage - Supply: 5V (power requirement)
• Orientation: Vertical (mounting axis)

Important Compatibility Parameters:

• Mounting Type: PCB Through Hole (installation method)
• Termination Style: PC Pin (connection interface)
• Detent: No (operational characteristic)
• Built-in Switch: No (integrated functionality)

The CUI Devices C14N16N-C3 meets all critical matching parameters and important compatibility parameters. Variations in actuator diameter (1/4" vs. 3/16"), rotational life specification (1M vs. 500K cycles), and mounting flexibility (Panel + PCB Through Hole vs. PCB Through Hole only) represent functional enhancements or expanded capability rather than incompatibilities.

Engineering Selection Recommendations

The CUI Devices C14N16N-C3 is a direct functional substitute for the Grayhill 62P22-N0 based on equivalence across all critical electrical and mechanical parameters. Selection of this substitute is supported by the following engineering factors:

Compliance and Regulatory Status: The C14N16N-C3 maintains RoHS3 compliance, which exceeds the RoHS compliance of the original part. Both components are classified under identical HTSUS code 8543.70.4500 and ECCN EAR99, confirming regulatory alignment.

Product Lifecycle Status: The Grayhill 62P22-N0 is obsolete, while the CUI Devices C14N16N-C3 is in active production. This status difference ensures long-term availability and supply chain continuity for the substitute component.

Electrical Compatibility: Both encoders operate at 5V supply voltage with identical 16 PPR quadrature output, ensuring direct signal compatibility with existing control electronics and firmware without modification.

Mechanical Considerations: The actuator diameter difference (1/4" vs. 3/16") requires verification against the specific shaft coupling or knob interface in the target application. The substitute's larger diameter may require mechanical adaptation depending on the mechanical assembly design.

Performance Enhancement: The C14N16N-C3 specifies 1M rotational life cycles compared to the 62P22-N0's 500K cycles, representing a 2x durability improvement. This enhancement does not create incompatibility and may extend system service life.

Frequently Asked Questions (FAQ)

Q: Can the CUI Devices C14N16N-C3 directly replace the Grayhill 62P22-N0 in existing PCB assemblies?

A: Electrical and signal compatibility is direct. The PC pin termination and 5V quadrature output are identical. Mechanical compatibility depends on the actuator shaft interface. The 1/4" diameter actuator of the C14N16N-C3 differs from the 3/16" diameter of the 62P22-N0. If the existing mechanical coupling (shaft coupler, knob, or drive mechanism) is sized for 3/16" diameter, mechanical adaptation is required.

Q: Are there any firmware or software changes required when substituting the C14N16N-C3 for the 62P22-N0?

A: No. Both encoders output identical 16 PPR quadrature (incremental) signals at 5V. Existing firmware and signal processing logic require no modification.

Q: What is the difference in product status between these two parts?

A: The Grayhill 62P22-N0 is obsolete and no longer manufactured. The CUI Devices C14N16N-C3 is in active production. This means the substitute is available from current inventory and will continue to be manufactured, ensuring long-term supply availability.

Q: Does the C14N16N-C3 support panel mounting in addition to PCB through-hole mounting?

A: Yes. The C14N16N-C3 supports both panel and PCB through-hole mounting configurations. The original 62P22-N0 supports PCB through-hole mounting only. This expanded mounting flexibility does not affect substitution compatibility but may provide additional design flexibility for new applications.

Q: Are the moisture sensitivity levels identical?

A: Yes. Both the Grayhill 62P22-N0 and CUI Devices C14N16N-C3 are classified as MSL 1 (Unlimited), indicating no moisture sensitivity restrictions and unlimited shelf life under standard storage conditions.

Q: What is the inventory status of the substitute part?

A: The CUI Devices C14N16N-C3 has 1029 pieces in new original stock, ensuring immediate availability for procurement and implementation.
