Substitute Part Grouping Explanation

Substitution eligibility for the 26GS45-01-1-08S-C is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part 26GSD45-01-1-AJS qualifies as a direct equivalent based on the following matching criteria:

Critical Matching Parameters:

• Encoder Type: Mechanical
• Output Type: Gray Code (Absolute)
• Pulses per Revolution: 8
• 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: 25K cycles minimum
• Manufacturer: Grayhill Inc. (Series 26 family)
• Compliance: RoHS Compliant, REACH Unaffected

Both parts belong to the Grayhill Series 26 rotary encoder family and maintain identical functional specifications, mechanical interfaces, and regulatory compliance status.

Parameter Comparison

Engineering Selection Recommendations

Both the 26GS45-01-1-08S-C and 26GSD45-01-1-AJS maintain Active product status within the Grayhill Series 26 encoder portfolio. Selection between these parts is based on availability and procurement logistics rather than functional differentiation.

Compliance and Certification Basis:

• Both parts carry RoHS Compliant certification, meeting EU Directive 2011/65/EU requirements
• Both parts maintain REACH Unaffected status, indicating no restriction under REACH Regulation (EC) 1907/2006
• Both parts are classified under ECCN EAR99 and HTSUS 8543.70.4500
• Moisture Sensitivity Level 1 (Unlimited) indicates no moisture-related handling restrictions for either part

Selection Criteria: The 26GSD45-01-1-AJS substitute part is functionally and mechanically equivalent to the 26GS45-01-1-08S-C. Component selection should be based on current inventory availability, supplier lead times, and procurement cost considerations. No technical re-qualification is required when transitioning between these parts within the same assembly design.

Frequently Asked Questions (FAQ)

Q: Are the 26GS45-01-1-08S-C and 26GSD45-01-1-AJS directly interchangeable?

A: Yes. Both parts are mechanically and electrically identical across all specified parameters. They share identical encoder type, output format (Gray Code Absolute), 8 PPR resolution, actuator geometry, detent functionality, mounting configuration, and termination style. Direct substitution is supported without circuit or mechanical redesign.

Q: What determines substitution eligibility for these rotary encoders?

A: Substitution is determined by exact matching of: encoder type (mechanical), output type (Gray Code Absolute), pulses per revolution (8), actuator type (1/8" Dia Flatted End), detent presence, mounting type (Panel, PCB Through Hole), orientation (Vertical), termination style (PC Pin), and rotational life specification (25K cycles minimum). Both parts meet all these criteria.

Q: Do these parts require different handling or storage procedures?

A: No. Both parts carry identical Moisture Sensitivity Level 1 (Unlimited), indicating no special moisture-related storage or handling requirements. Standard component storage practices apply to both parts.

Q: Are there any compliance differences between these parts?

A: No. Both parts carry identical RoHS Compliant and REACH Unaffected designations. Both are classified under the same ECCN (EAR99) and HTSUS (8543.70.4500) codes. No compliance re-evaluation is required when substituting between these parts.

Q: What is the difference between the part numbers 26GS45-01-1-08S-C and 26GSD45-01-1-AJS?

A: The part numbers reflect different internal Grayhill manufacturing designations or revision levels within the Series 26 encoder family. The alphanumeric suffixes (08S-C versus AJS) indicate manufacturing or configuration variants, but all specified electrical and mechanical parameters remain identical.

Q: Can these parts be used in new designs interchangeably?

A: Yes. Both parts are Active status products with identical specifications. Either part number can be specified in new designs. The choice between them should be based on supplier availability and lead time considerations.
