Substitute Part Grouping Explanation

Substitution of the CDBM240L-G is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Criteria:

• Voltage - DC Reverse (Vr) (Max): 40 V
• Current - Average Rectified (Io): 2 A
• Technology: Schottky
• Speed classification: Fast Recovery ≤ 500ns, > 200mA (Io)

Mechanical Equivalence Criteria:

• Package / Case: SOD-123T
• Mounting Type: Surface Mount
• Supplier Device Package: Mini SMA/SOD-123

Compliance Equivalence Criteria:

• RoHS Status: ROHS3 Compliant
• REACH Status: REACH Unaffected

The CDBM240L-HF qualifies as a direct substitute based on identical electrical ratings, mechanical packaging, and regulatory compliance. The primary distinction is product status (Active vs. Obsolete) and forward voltage performance at rated current.

Parameter Comparison

Engineering Selection Recommendations

The CDBM240L-HF is the direct substitute for the obsolete CDBM240L-G. Selection of the substitute part is supported by the following factors:

Product Status: The CDBM240L-HF maintains Active product status, ensuring continued availability and manufacturer support, whereas the CDBM240L-G is classified as Obsolete.

Electrical Performance: Both parts meet identical voltage and current specifications. The CDBM240L-HF exhibits improved forward voltage performance (380 mV vs. 400 mV @ 2 A), resulting in lower power dissipation during operation.

Regulatory Compliance: Both parts maintain ROHS3 compliance and REACH Unaffected status, satisfying environmental and regulatory requirements.

Packaging and Mounting: Identical SOD-123T package and surface mount configuration ensure mechanical and thermal compatibility with existing PCB designs.

Frequently Asked Questions (FAQ)

Q: Can CDBM240L-HF be used as a direct replacement for CDBM240L-G in existing designs?

A: Yes. The CDBM240L-HF is electrically and mechanically equivalent to the CDBM240L-G across all critical parameters including voltage rating, current rating, package type, and operating temperature range. Both parts are manufactured by Comchip Technology and share identical SOD-123T packaging.

Q: What is the difference between CDBM240L-G and CDBM240L-HF?

A: The primary differences are product status and forward voltage specification. The CDBM240L-G is Obsolete, while the CDBM240L-HF is Active. The CDBM240L-HF exhibits lower forward voltage (380 mV vs. 400 mV @ 2 A), which reduces power dissipation. Both parts share identical reverse voltage, current rating, and package specifications.

Q: Are there packaging differences between these parts?

A: Both parts use SOD-123T surface mount packaging. The CDBM240L-G is supplied in standard packaging, while the CDBM240L-HF is supplied in Tape & Reel (TR) format. Both are compatible with automated assembly processes.

Q: Do these parts have the same thermal characteristics?

A: Yes. Both parts operate across the identical junction temperature range of -55°C to 125°C and share identical capacitance specifications (160 pF @ 4V, 1MHz).

Q: Are both parts RoHS and REACH compliant?

A: Yes. Both the CDBM240L-G and CDBM240L-HF are ROHS3 Compliant and REACH Unaffected, meeting current environmental and regulatory standards.
