Key Parameters

Substitute Part Grouping Explanation

Substitution of the CDBER0140L-HF is determined by strict equivalence across the following electrical parameters: reverse voltage rating (40 V), average rectified current (100 mA), forward voltage drop (550 mV @ 100 mA), reverse leakage current (30 µA @ 10 V), and Schottky technology classification. Mechanical compatibility is evaluated based on surface mount mounting type and package form factor. Compliance requirements (RoHS3, REACH, MSL Level 1) must be maintained across all substitutes.

Two substitute parts are identified:

CDBUR0140L - Manufacturer recommended substitute with identical electrical specifications but different package form factor (0603/SOD-523F instead of 0503/SOD-723F). Active product status with higher inventory availability.

CDBER0140L - Parametric equivalent with identical package form factor (0503/SOD-723F) and electrical specifications. Active product status.

Parameter Comparison

Engineering Selection Recommendations

For direct package compatibility: CDBER0140L is the appropriate selection when the 0503/SOD-723F package form factor is required for PCB layout constraints. This part maintains identical electrical specifications and package dimensions while offering active product status and improved inventory availability compared to the obsolete CDBER0140L-HF.

For flexible package accommodation: CDBUR0140L is the manufacturer-recommended substitute when PCB layout permits use of the larger 0603/SOD-523F package form factor. This part delivers identical electrical performance with the highest inventory availability and active product status designation.

Both substitute parts maintain full compliance with RoHS3 and REACH requirements, ensuring regulatory continuity. MSL Level 1 classification applies to all parts, indicating unlimited shelf life under standard storage conditions.

Frequently Asked Questions (FAQ)

Q: Can CDBUR0140L replace CDBER0140L-HF in existing designs?

A: CDBUR0140L provides electrical equivalence across all specified parameters (40 V reverse voltage, 100 mA current rating, 550 mV forward voltage, 30 µA reverse leakage). However, the package form factor differs: CDBUR0140L uses 0603/SOD-523F versus the original 0503/SOD-723F. PCB layout modification is required if the larger package cannot be accommodated in the existing footprint.

Q: What is the difference between CDBER0140L and CDBER0140L-HF?

A: Both parts share identical electrical specifications and the same 0503/SOD-723F package form factor. The primary distinction is product status: CDBER0140L-HF is obsolete, while CDBER0140L is active. CDBER0140L is the direct equivalent for ongoing procurement.

Q: Are all three parts interchangeable from an electrical standpoint?

A: Yes. CDBUR0140L and CDBER0140L both match the electrical specifications of CDBER0140L-HF: 40 V reverse voltage, 100 mA average rectified current, 550 mV forward voltage at 100 mA, and 30 µA reverse leakage current at 10 V. Mechanical interchangeability depends on package form factor accommodation in the circuit board design.

Q: Which substitute should be selected for new designs?

A: Selection depends on PCB layout constraints. If the 0503/SOD-723F package is required, use CDBER0140L. If the 0603/SOD-523F package is acceptable, CDBUR0140L is the manufacturer-recommended option with superior inventory availability.

Q: Do all substitute parts maintain the same compliance certifications?

A: Yes. CDBUR0140L and CDBER0140L both comply with RoHS3, maintain REACH Unaffected status, and carry MSL Level 1 classification, matching the compliance profile of the original CDBER0140L-HF.
