Grayhill 25LR22-H Rotary Encoder: Equivalent & Substitute Parts

Part Overview

The Grayhill 25LR22-H is an active mechanical rotary encoder with 16 pulses per revolution (PPR) hexadecimal absolute output. This vertical-orientation encoder features a 1/4" diameter flatted end actuator and is designed for panel and PCB through-hole mounting applications. The product is actively manufactured and maintained in inventory, with ROHS3 compliance and unlimited moisture sensitivity rating. Substitute parts are identified when original stock availability is limited or when equivalent functional specifications are required for system integration.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 25LR22-H is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Encoder Type: Mechanical
• Output Type: Hexadecimal (Absolute)
• Pulses per Revolution: 16
• Actuator Type: 1/4" Dia Flatted End
• Detent: Yes
• Built-in Switch: No
• Mounting Type: Panel, PCB Through Hole
• Orientation: Vertical
• Termination Style: PC Pin
• Rotational Life: 100K cycles minimum
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

The Grayhill 25LB22-H meets all mandatory matching parameters and qualifies as a direct substitute. Both parts belong to the Grayhill 25L series and share identical functional and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

Both the 25LR22-H and 25LB22-H are active products manufactured by Grayhill Inc. with full ROHS3 compliance and REACH unaffected status. Selection between these parts should be based on inventory availability and lead time requirements, as both parts meet identical electrical, mechanical, and regulatory specifications.

The 25LB22-H currently maintains higher inventory levels (1325 pcs) compared to the 25LR22-H (1042 pcs), making it suitable for applications where extended supply chain continuity is required. Both parts are suitable for direct substitution in panel-mounted and PCB through-hole applications requiring 16 PPR hexadecimal absolute output with mechanical detent operation.

Frequently Asked Questions (FAQ)

Q: Can the 25LB22-H be used as a direct replacement for the 25LR22-H?

A: Yes. Both parts are mechanically and electrically identical across all specified parameters, including encoder type, output format, pulse resolution, actuator geometry, mounting configuration, and termination style. No circuit modifications or mechanical redesign is required.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution is valid only when the following parameters match exactly: mechanical encoder type, hexadecimal absolute output, 16 PPR resolution, 1/4" flatted end actuator, detent operation, vertical orientation, panel and PCB through-hole mounting capability, PC pin termination, 100K minimum rotational life, and ROHS3 compliance with MSL 1 rating.

Q: Are there any differences in packaging or supply format?

A: Both parts are supplied in bulk packaging format. No differences in packaging configuration exist between the 25LR22-H and 25LB22-H.

Q: What is the difference between the 25LR22 and 25LB22 base product numbers?

A: The base product numbers (25LR22 vs. 25LB22) indicate different internal design variants within the Grayhill 25L series. However, when both are specified with the -H suffix and identical parameter sets, they function as complete equivalents for the specified application requirements.

Q: Are both parts compliant with current regulatory standards?

A: Yes. Both the 25LR22-H and 25LB22-H are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99 with HTSUS code 8543.70.4500. Both parts meet current regulatory requirements for industrial and commercial applications.
