Engineering Selection Recommendations

CDBMT230L-HF is the direct functional equivalent for CDBMT230L-G applications. Selection criteria are based on the following factors:

Product Status: CDBMT230L-HF maintains active product status with Comchip Technology, ensuring long-term availability and manufacturing support. CDBMT230L-G is classified as obsolete, presenting supply risk for new production.

Compliance & Certifications: Both parts are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements. MSL rating of 1 (Unlimited) indicates no moisture sensitivity constraints during storage or handling.

Electrical Equivalence: All electrical parameters are identical, including voltage ratings, current capacity, forward voltage characteristics, and recovery speed specifications. Direct circuit substitution is supported without design modification.

Packaging Consideration: CDBMT230L-HF is supplied in Tape & Reel format, standard for automated assembly processes. CDBMT230L-G bulk packaging may require manual handling or reeling services, increasing production overhead.

For new designs and ongoing production, CDBMT230L-HF is the appropriate selection. Existing inventory of CDBMT230L-G may be utilized for current stock depletion, with transition to CDBMT230L-HF for future procurement.

Frequently Asked Questions (FAQ)

Q: Can CDBMT230L-HF be used as a direct replacement for CDBMT230L-G in existing circuits?

A: Yes. All electrical and mechanical parameters are identical. The parts are pin-compatible in SOD-123H packages and require no circuit modifications.

Q: What is the difference between CDBMT230L-G and CDBMT230L-HF?

A: The primary differences are product status and packaging format. CDBMT230L-G is obsolete with bulk packaging; CDBMT230L-HF is active with Tape & Reel packaging. Electrical specifications are identical.

Q: Are there any thermal or performance differences between these parts?

A: No. Both parts share identical operating temperature ranges (-55°C to 100°C), forward voltage characteristics (400 mV @ 2A), and reverse leakage specifications (1 mA @ 30V).

Q: Does the Tape & Reel packaging of CDBMT230L-HF affect circuit performance?

A: No. Packaging format does not affect electrical performance. Tape & Reel is a supply and assembly format advantage, not a functional difference.
