CDBHM140L-G Bridge Rectifier Equivalent & Substitute Parts

Part Overview

The CDBHM140L-G is a single-phase bridge rectifier manufactured by Comchip Technology, utilizing Schottky diode technology for surface mount applications. This component is rated for 40 V peak reverse voltage with 1 A average rectified current and is packaged in the TO-269AA, 4-BESOP form factor. The part maintains active product status and is ROHS3 compliant. Substitute parts are identified when electrical parameters, mechanical packaging, and compliance certifications remain identical across the component lifecycle or manufacturing variations.

Substitute Part Grouping Explanation

Substitution eligibility for the CDBHM140L-G is determined by strict equivalence across the following critical parameters:

• Diode Type: Single Phase
• Technology: Schottky
• Voltage - Peak Reverse (Max): 40 V
• Current - Average Rectified (Io): 1 A
• Voltage - Forward (Vf) (Max) @ If: 550 mV @ 1 A
• Current - Reverse Leakage @ Vr: 500 µA @ 40 V
• Operating Temperature Range: -55°C to 125°C (TJ)
• Package / Case: TO-269AA, 4-BESOP
• Supplier Device Package: MBS
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

The CDBHM140L-HF meets all these criteria and is classified as a parametric equivalent. Both parts share identical electrical specifications, thermal characteristics, and mechanical packaging, differing only in manufacturing lot designation or supplier tape configuration.

Parameter Comparison

Engineering Selection Recommendations

Both CDBHM140L-G and CDBHM140L-HF are active products manufactured by Comchip Technology with identical electrical and mechanical specifications. Selection between these parts is based on availability and supply chain requirements rather than technical differentiation. Both parts maintain ROHS3 compliance and REACH unaffected status, meeting regulatory requirements for industrial and commercial applications. The CDBHM140L-HF currently maintains higher inventory levels (12,200 pcs) compared to CDBHM140L-G (792 pcs), making it suitable for high-volume procurement scenarios where supply continuity is a priority.

Frequently Asked Questions (FAQ)

Q: Can CDBHM140L-HF be used as a direct replacement for CDBHM140L-G?

A: Yes. Both parts are parametric equivalents with identical electrical ratings, thermal characteristics, and mechanical packaging. No circuit modifications or design changes are required for substitution.

Q: Are there any differences in the TO-269AA, 4-BESOP package between these parts?
