Parameter Comparison

Engineering Selection Recommendations

Primary Selection Criteria:

The 25LR22-G-Z and 25LB22-G are functionally equivalent components. Selection between these parts should be based on the following factors:

1. Inventory Availability: The 25LB22-G offers higher current stock (1149 units) compared to the 25LR22-G-Z (742 units), providing improved supply chain reliability.

2. Product Status: Both parts maintain Active product status, ensuring continued manufacturer support and availability.

3. Compliance Certification: Both parts are ROHS3 Compliant and REACH Unaffected, meeting current regulatory requirements for electronic component manufacturing and distribution.

4. Electrical and Mechanical Compatibility: All critical parameters—output type, PPR rating, actuator geometry, mounting configuration, and termination style—are identical between the two parts, ensuring direct functional substitution without circuit or mechanical redesign.

5. Environmental Specifications: Both parts share identical MSL ratings (1 - Unlimited), indicating equivalent moisture handling and storage requirements.

The 25LB22-G is suitable as a direct substitute for the 25LR22-G-Z in applications where the specified electrical output (16 PPR Gray Code Absolute), mechanical form factor (vertical orientation, 1/4" flatted actuator), and mounting configuration (panel and PCB through-hole) are required.

Frequently Asked Questions (FAQ)

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