CDBER40-HF Equivalent & Substitute Parts

Part Overview

The CDBER40-HF is a Schottky diode manufactured by Comchip Technology, rated for 40V DC reverse voltage with 200mA average rectified current in a 0503/SOD-723F surface mount package. This component is classified as obsolete product status. Due to its obsolete designation, identifying equivalent substitute parts with identical electrical and mechanical specifications is essential for design continuity and procurement planning.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CDBER40-HF is determined by strict equivalence across the following critical parameters:

• Voltage - DC Reverse (Vr) (Max): 40 V
• Current - Average Rectified (Io): 200 mA
• Voltage - Forward (Vf) (Max) @ If: 1 V @ 40 mA
• Reverse Recovery Time (trr): 5 ns
• Current - Reverse Leakage @ Vr: 200 nA @ 30 V
• Capacitance @ Vr, F: 5 pF @ 0V, 1MHz
• Package / Case: 0503 (1308 Metric)
• Mounting Type: Surface Mount
• Technology: Schottky

The CDBER40 (without the -HF suffix) meets all electrical and mechanical specifications identical to the main part. The primary distinction is product status and packaging configuration.

Parameter Comparison

Engineering Selection Recommendations

The CDBER40 is the direct substitute for the obsolete CDBER40-HF. Both parts are manufactured by Comchip Technology and share identical electrical characteristics and mechanical specifications. The CDBER40 maintains active product status, ensuring ongoing availability and supply chain continuity.

Both parts comply with ROHS3 and REACH requirements. Moisture Sensitivity Level is rated at MSL 1 (Unlimited) for both variants, indicating no moisture sensitivity constraints during storage or handling.

The CDBER40 is supplied in Tape & Reel (TR) packaging, which is the standard format for high-volume surface mount assembly operations. This packaging configuration is suitable for automated pick-and-place equipment used in PCB manufacturing.

Frequently Asked Questions (FAQ)

Q: Can CDBER40 directly replace CDBER40-HF in existing designs?

A: Yes. The CDBER40 is electrically and mechanically equivalent to the CDBER40-HF. All critical parameters including voltage rating, current capacity, forward voltage, reverse recovery time, leakage current, and capacitance are identical. Both use the same 0503/SOD-723F package for surface mount applications.

Q: What is the difference between CDBER40-HF and CDBER40?

A: The primary differences are product status and packaging format. CDBER40-HF is classified as obsolete, while CDBER40 is active. CDBER40 is supplied in Tape & Reel (TR) packaging, which is standard for automated assembly. The -HF suffix designation on the main part does not indicate a functional difference in electrical or mechanical performance.

Q: Are there any compliance or certification differences?

A: No. Both CDBER40-HF and CDBER40 are ROHS3 compliant and REACH unaffected. Both carry MSL 1 (Unlimited) moisture sensitivity rating. Regulatory and environmental compliance status is identical.

Q: Is the 0503/SOD-723F package suitable for my application?

A: The 0503 (1308 Metric) package is a surface mount form factor. Compatibility depends on your PCB design, footprint specifications, and assembly equipment. Verify that your design accommodates this specific package geometry and that your manufacturing process supports 0503 component placement.

Q: What is the inventory status for these parts?

A: CDBER40-HF has 1062 pieces in stock as new original inventory. CDBER40 has 954 pieces in stock as new original inventory. Both are available for immediate procurement.
