Substitute Part Grouping Explanation

Substitution of the CDBHA15100-HF is determined by strict equivalence across the following electrical and mechanical parameters:

Electrical Equivalence Criteria:

• Voltage - DC Reverse (Vr) (Max): 100 V
• Current - Average Rectified (Io): 15 A
• Voltage - Forward (Vf) (Max) @ If: 700 mV @ 15 A
• Speed: Fast Recovery ≤ 500ns, > 200mA (Io)
• Current - Reverse Leakage @ Vr: 250 µA @ 100 V
• Operating Temperature - Junction: -55°C to 150°C
• Technology: Schottky

Mechanical Equivalence Criteria:

• Mounting Type: Surface Mount
• Package / Case: TO-277, 3-PowerDFN
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

Substitute parts identified for the CDBHA15100-HF meet all electrical specifications and are compatible with the same mounting and package requirements. Variations in supplier device package designation (TO-277A, TO-277B, SMPC4.0) represent different physical package configurations within the TO-277 / 3-PowerDFN family and are mechanically interchangeable in standard surface mount applications.

Engineering Selection Recommendations

CDBHA15100-HF (Primary Selection)

The CDBHA15100-HF is the recommended primary selection for new designs. This part carries Active product status, indicating ongoing manufacturer support and availability. It is RoHS3 compliant and carries unlimited moisture sensitivity level (MSL 1), suitable for standard surface mount assembly processes without special handling requirements.

TSP15U100S (Secondary Selection)

The TSP15U100S is a parametric equivalent manufactured by Taiwan Semiconductor Corporation. This part meets all electrical and mechanical specifications of the CDBHA15100-HF. However, it is designated as Not For New Designs, indicating that Taiwan Semiconductor does not recommend this part for new product development. This part is suitable for legacy system support, repair, or replacement applications where existing designs already incorporate this component. Inventory availability is substantial at 57,594 pieces.

TSPB15U100S (Tertiary Selection)

The TSPB15U100S is a parametric equivalent manufactured by Taiwan Semiconductor Corporation. This part meets all electrical and mechanical specifications of the CDBHA15100-HF. It is designated as Discontinued at DiGi Electronics, indicating limited availability through standard distribution channels. This part is suitable only for legacy system support or repair applications where existing designs already incorporate this component. Inventory availability is 21,628 pieces through alternative suppliers.

Frequently Asked Questions (FAQ)

Q: Can TSP15U100S be used as a direct replacement for CDBHA15100-HF in new designs?

A: TSP15U100S meets all electrical and mechanical specifications for direct substitution. However, it carries a Not For New Designs product status designation. For new product development, CDBHA15100-HF is the recommended selection. TSP15U100S is suitable for legacy system support or repair applications.

Q: What is the difference between TO-277A, TO-277B, and SMPC4.0 package designations?

A: All three designations represent variants within the TO-277 / 3-PowerDFN package family. These are mechanically interchangeable in standard surface mount applications. The different supplier device package designations reflect manufacturer-specific packaging conventions but do not affect electrical performance or board-level compatibility.

Q: Are all three parts RoHS3 compliant?

A: Yes. CDBHA15100-HF, TSP15U100S, and TSPB15U100S are all RoHS3 compliant with unlimited moisture sensitivity level (MSL 1).

Q: Why is TSPB15U100S marked as discontinued?

A: TSPB15U100S is discontinued at DiGi Electronics, indicating it is no longer available through this primary distribution channel. However, inventory may be available through alternative suppliers. This part is suitable only for legacy system support or repair applications.

Q: Do all substitute parts have identical electrical performance?

A: Yes. CDBHA15100-HF, TSP15U100S, and TSPB15U100S share identical electrical specifications: 100 V DC reverse voltage, 15 A average rectified current, 700 mV forward voltage at 15 A, fast recovery speed ≤ 500ns, 250 µA reverse leakage current at 100 V, and -55°C to 150°C operating temperature range.

Q: What is the moisture sensitivity level (MSL) and why does it matter?

A: Moisture Sensitivity Level (MSL) 1 indicates unlimited shelf life and no special moisture control requirements during storage or assembly. All three parts carry MSL 1, eliminating moisture-related handling constraints in manufacturing environments.

Q: Can these parts be used interchangeably on the same printed circuit board?

A: Yes. All three parts are surface mount components with compatible TO-277 / 3-PowerDFN package configurations. They are mechanically and electrically interchangeable on the same printed circuit board layout.
