Grayhill 26AS22-01-1-16S-F Rotary Encoder: Equivalent & Substitute Parts

Part Overview

The Grayhill 26AS22-01-1-16S-F is a mechanical rotary encoder with 16 pulses per revolution (PPR) hexadecimal absolute output. This encoder is designed for panel and PCB through-hole mounting applications requiring vertical orientation with a 1/8" diameter flatted end actuator. The part is currently in active production status with 628 units in stock. Alternative models may be required due to inventory constraints, application-specific termination requirements, or supply chain considerations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 26AS22-01-1-16S-F 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: 1/8" Dia Flatted End
• Detent: Yes
• Built-in Switch: No
• Mounting Type: Panel, PCB Through Hole
• Orientation: Vertical
• Termination Style: PC Pin
• Rotational Life (Cycles Min): 25K

The substitute part 26AS22-01-1-08S meets all mandatory matching parameters and belongs to the same Grayhill 26 series base product family (26AS22). Both parts are manufactured by Grayhill Inc. and maintain identical mechanical and electrical specifications for the critical functional parameters listed above.

Parameter Comparison

Engineering Selection Recommendations

Both the 26AS22-01-1-16S-F and 26AS22-01-1-08S are active production parts manufactured by Grayhill Inc. with full compliance to RoHS and REACH regulations. The substitute part 26AS22-01-1-08S carries ROHS3 compliance, which represents an updated RoHS certification standard and is fully compatible with applications requiring RoHS compliance.

Selection between these parts should be based on:

1. Inventory Availability: The substitute part 26AS22-01-1-08S has higher current inventory (702 units) compared to the main part (628 units).

2. Regulatory Compliance: Both parts meet environmental and regulatory requirements. The ROHS3 designation on the substitute part indicates compliance with the most current RoHS standard.

3. Functional Equivalence: All mechanical, electrical, and operational parameters are identical between the two parts, ensuring direct functional interchangeability in applications designed for either model number.

4. Supply Chain Continuity: Both parts are in active production status, supporting long-term availability for production and replacement applications.

Frequently Asked Questions (FAQ)

Q: Can the 26AS22-01-1-08S be used as a direct replacement for the 26AS22-01-1-16S-F?

A: Yes. The 26AS22-01-1-08S is functionally equivalent to the 26AS22-01-1-16S-F across all critical parameters including encoder type, output type, pulses per revolution, actuator type, detent function, mounting type, orientation, termination style, and rotational life. Both parts are mechanically and electrically interchangeable.

Q: What is the difference between RoHS Compliant and ROHS3 Compliant?

A: ROHS3 represents the third iteration of the RoHS (Restriction of Hazardous Substances) directive, incorporating updated standards and requirements. Both designations indicate compliance with hazardous substance restrictions. ROHS3 compliance on the substitute part reflects adherence to the current regulatory standard.

Q: Are the termination styles identical between these parts?

A: Yes. Both the 26AS22-01-1-16S-F and 26AS22-01-1-08S use PC Pin termination style, ensuring compatibility with identical PCB layouts and connector interfaces.

Q: Do both parts support the same mounting configurations?

A: Yes. Both parts support Panel and PCB Through Hole mounting types with vertical orientation, allowing installation in identical mechanical assemblies.

Q: What is the significance of the 16 PPR specification?

A: The 16 pulses per revolution specification defines the encoder's resolution. Both the main part and substitute part maintain this 16 PPR hexadecimal absolute output, ensuring identical position resolution and data output format for connected control systems.

Q: Are there any packaging differences between these parts?

A: Both parts are supplied in Bulk packaging. No packaging format differences exist between the two models.

Q: What does "Hexadecimal (Absolute)" output mean?

A: Hexadecimal absolute output indicates that the encoder provides position data in hexadecimal format representing absolute position values. This output type is identical on both the main part and substitute part.
