Grayhill 25LB22-H-Z Rotary Encoder Mechanical 16PPR Equivalent & Substitute Parts

Part Overview

The Grayhill 25LB22-H-Z is an active 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 encoder features detent positioning and is rated for 100,000 rotational cycles minimum. Finding equivalent and substitute parts is necessary when managing inventory constraints, ensuring supply chain continuity, or matching specific procurement requirements while maintaining identical electrical and mechanical performance characteristics.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 25LB22-H-Z is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part must match the following criteria:

Critical Substitution 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 Compliance: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Parts meeting all these parameters are classified as direct equivalents and may be used interchangeably in applications designed for the 25LB22-H-Z.

Parameter Comparison

Engineering Selection Recommendations

The 25LB22-H serves as a direct equivalent substitute for the 25LB22-H-Z. Both parts are manufactured by Grayhill Inc., belong to the 25L series, and maintain active product status. Both components satisfy ROHS3 compliance requirements and REACH unaffected status, making them suitable for applications subject to environmental and regulatory restrictions. The identical electrical output characteristics (16 PPR hexadecimal absolute), mechanical configuration (1/4" flatted end actuator, vertical orientation, detent positioning), and durability rating (100K rotational cycles) ensure functional interchangeability. Selection between these parts may be based on inventory availability, procurement lead times, or packaging preferences, as no technical differentiation exists between them.

Frequently Asked Questions (FAQ)

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

A: Yes. The 25LB22-H is a direct equivalent. All electrical parameters (16 PPR hexadecimal absolute output), mechanical specifications (1/4" flatted end actuator, vertical orientation, detent), mounting characteristics (panel and PCB through-hole), and durability ratings (100K cycles) are identical. Both parts are ROHS3 compliant and REACH unaffected.

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

A: Substitution requires exact matching of encoder type (mechanical), output type (hexadecimal absolute), pulses per revolution (16), actuator geometry (1/4" flatted end), detent presence, mounting type (panel/PCB through-hole), orientation (vertical), termination style (PC pin), and rotational life rating (100K cycles minimum).

Q: Are there packaging differences between the 25LB22-H-Z and 25LB22-H?

A: Both parts are supplied in bulk packaging. No packaging differentiation is specified in the technical parameters.

Q: What compliance certifications apply to both parts?

A: Both the 25LB22-H-Z and 25LB22-H are ROHS3 compliant and REACH unaffected. Both carry EAR99 export classification and HTSUS code 8543.70.4500.

Q: Is the moisture sensitivity level the same for both parts?

A: Yes. Both parts have Moisture Sensitivity Level 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.
