Substitute Part Grouping Explanation

The CL-SB-12B-02T qualifies as a substitute for the CAS-120B based on the following shared electrical and mechanical parameters:

• Both parts maintain SPDT circuit configuration with On-On switch function
• Both feature surface mount construction with gull wing termination
• Both utilize gold-plated copper-based contacts with polyamide actuators
• Both operate across the identical temperature range of -40°C to 85°C
• Both carry MSL 1 (Unlimited) moisture sensitivity classification
• Both are manufactured by Nidec Components Corporation and maintain active product status

The CL-SB-12B-02T differs in current capacity (200mA versus 100mA), voltage rating (12V versus 6V), electrical life (10,000 cycles versus 2,000 cycles), and packaging format (Tape & Reel versus Bulk). These differences indicate the substitute part provides enhanced electrical performance specifications while maintaining functional compatibility for SPDT switching applications.

Parameter Comparison

Engineering Selection Recommendations

Both the CAS-120B and CL-SB-12B-02T maintain active product status with identical REACH compliance and ECCN classifications, confirming regulatory equivalence. The CL-SB-12B-02T provides higher current capacity (200mA) and voltage rating (12V) with extended electrical life (10,000 cycles), making it suitable for applications requiring greater electrical performance margins. Selection between these parts depends on circuit voltage and current requirements. The CAS-120B remains appropriate for 6V, 100mA applications, while the CL-SB-12B-02T accommodates 12V, 200mA specifications. Both parts share identical operating temperature ranges and moisture sensitivity classifications, ensuring thermal and environmental compatibility across equivalent applications.

Frequently Asked Questions (FAQ)

Q: Can the CL-SB-12B-02T replace the CAS-120B in all applications?

A: The CL-SB-12B-02T is functionally compatible as an SPDT switch with identical circuit configuration, mounting type, and termination style. However, the higher voltage rating (12V) and current capacity (200mA) must align with circuit design specifications. Direct substitution is valid only when the application circuit supports these higher electrical parameters.

Q: What are the key differences between these parts?

A: The primary differences are current rating (100mA versus 200mA), voltage rating (6V versus 12V), electrical life (2,000 versus 10,000 cycles), and packaging format (Bulk versus Tape & Reel). Both parts maintain identical operating temperature ranges, contact materials, and moisture sensitivity classifications.

Q: Are there packaging considerations for substitution?

A: The CAS-120B is supplied in bulk packaging, while the CL-SB-12B-02T is supplied in Tape & Reel format. Packaging selection depends on assembly process requirements and inventory management practices. Both formats are compatible with standard surface mount assembly equipment.

Q: Do both parts meet the same regulatory requirements?

A: Both parts carry REACH Unaffected status and EAR99 ECCN classification, confirming equivalent regulatory compliance. Both maintain MSL 1 (Unlimited) moisture sensitivity levels, indicating identical handling and storage requirements.

Q: What determines whether a substitute part is acceptable?

A: Substitution validity depends on circuit voltage and current requirements matching or being lower than the substitute part's ratings, identical SPDT circuit configuration, compatible surface mount construction, and matching operating temperature range. Both parts satisfy these criteria for SPDT switching applications.
