Key Parameters

Substitute Part Grouping Explanation

Substitution of the B1200CA is determined by strict equivalence across the following parameters:

• Voltage clamping characteristic: Adjustable
• Technology platform: Mixed Technology
• Circuit configuration: Single circuit (1)
• Package specification: DO-214AA, SMB (3 Leads), Compak
• Mounting method: Surface Mount
• Application category: SLIC
• Moisture sensitivity: MSL 1 (Unlimited)

The B1200CALRP qualifies as a direct substitute based on identical specifications across all these parameters. The primary distinction between the main part and substitute relates to product status and packaging format.

Parameter Comparison

Engineering Selection Recommendations

The B1200CALRP is the direct equivalent substitute for the B1200CA. Both components share identical electrical and mechanical specifications within the Battrax® TVS device series.

Selection between these parts should be based on the following factors:

• Product Status: The B1200CA is obsolete. The B1200CALRP maintains active production status, ensuring long-term availability and supply chain continuity.
• RoHS Compliance: The B1200CALRP meets ROHS3 compliance requirements, while the B1200CA is non-compliant. Systems requiring RoHS-compliant components must use B1200CALRP.
• Packaging Requirements: The B1200CA is supplied in bulk packaging, while B1200CALRP is supplied in Tape & Reel format. Packaging selection depends on assembly process requirements and volume specifications.
• REACH Status: The B1200CALRP carries REACH Unaffected designation, providing regulatory clarity for European market applications.

Frequently Asked Questions (FAQ)

Q: Can B1200CALRP be used as a direct replacement for B1200CA in existing designs?

A: Yes. Both components are electrically and mechanically equivalent across all specified parameters, including voltage clamping, technology platform, circuit configuration, and package specification. The substitution is direct.

Q: What is the primary reason to transition from B1200CA to B1200CALRP?

A: The B1200CA is obsolete. The B1200CALRP is the active production equivalent, ensuring component availability and supply chain reliability for ongoing applications.

Q: Are there compliance differences between B1200CA and B1200CALRP?

A: Yes. The B1200CALRP is ROHS3 compliant and carries REACH Unaffected status. The B1200CA is RoHS non-compliant. Applications requiring regulatory compliance must use B1200CALRP.

Q: Does packaging format affect electrical performance?

A: No. The B1200CA (bulk packaging) and B1200CALRP (Tape & Reel) are electrically identical. Packaging format is determined by assembly process requirements and volume specifications only.

Q: Are both parts suitable for SLIC applications?

A: Yes. Both the B1200CA and B1200CALRP are specified for SLIC applications with identical performance characteristics.

Q: What is the moisture sensitivity level for these components?

A: Both components carry MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.
