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

Part Overview

The Grayhill 25LR22-H-Z is a mechanical rotary encoder with 16 pulses per revolution (PPR) hexadecimal absolute output. This component is designed for panel and PCB through-hole mounting applications requiring vertical orientation with a 1/4" diameter flatted end actuator. The part is currently in active production status with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Substitute parts are identified when inventory constraints, lead time requirements, or procurement preferences necessitate alternative sourcing while maintaining identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

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

• Encoder Type: Mechanical operation required
• Output Type: Hexadecimal (Absolute) format mandatory
• Pulses per Revolution: 16 PPR exact match
• Actuator Geometry: 1/4" diameter flatted end configuration
• Detent Function: Detent mechanism present
• Mounting Configuration: Panel and PCB through-hole compatibility
• Orientation: Vertical mounting only
• Termination: PC pin interface
• Rotational Life: Minimum 100K cycles
• Compliance: ROHS3 and REACH requirements

The substitute part 25LB22-H meets all specified parameters identically, establishing direct functional and mechanical interchangeability within the 25L series from Grayhill Inc.

Parameter Comparison

Engineering Selection Recommendations

Both the 25LR22-H-Z and 25LB22-H are active production components manufactured by Grayhill Inc. with identical electrical, mechanical, and compliance specifications. Selection between these parts is based on availability and procurement logistics rather than technical differentiation.

The 25LB22-H currently maintains higher inventory levels (1325 pcs) compared to the 25LR22-H-Z (847 pcs), making it suitable for applications where lead time optimization is a consideration. Both parts satisfy ROHS3 compliance and REACH unaffected status, ensuring regulatory compatibility in equivalent applications.

The interchangeability is absolute across all specified parameters: mechanical encoder operation, 16 PPR hexadecimal absolute output, 1/4" flatted end actuator, detent mechanism, panel and PCB through-hole mounting, vertical orientation, PC pin termination, and 100K minimum rotational life rating.

Frequently Asked Questions (FAQ)

Q: Can the 25LB22-H directly replace the 25LR22-H-Z in existing designs?

A: Yes. Both parts are mechanically and electrically identical across all specified parameters. No design modifications are required for substitution.

Q: What distinguishes the 25LR22-H-Z from the 25LB22-H?

A: The parts differ only in base product number designation (25LR22 versus 25LB22). All functional, mechanical, and compliance specifications are identical.

Q: Are there any mounting or orientation differences between these encoders?

A: No. Both parts feature identical mounting configurations (panel and PCB through-hole), vertical orientation, and 1/4" diameter flatted end actuator geometry.

Q: Do both parts meet the same compliance and regulatory requirements?

A: Yes. Both the 25LR22-H-Z and 25LB22-H are ROHS3 compliant, REACH unaffected, and carry MSL 1 (unlimited) moisture sensitivity rating.

Q: What is the rotational life specification for both encoders?

A: Both parts specify a minimum rotational life of 100K cycles, ensuring equivalent durability and operational longevity.

Q: Are the termination styles identical?

A: Yes. Both encoders use PC pin termination, ensuring compatibility with standard PCB through-hole and panel mounting interfaces.

Q: Can these parts be used interchangeably in applications requiring hexadecimal absolute output?

A: Yes. Both parts provide identical 16 PPR hexadecimal absolute output, making them fully interchangeable for applications requiring this output format.
