Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CDBER00340-HF is determined by strict equivalence across the following critical parameters:

Electrical Parameters (Must Match Exactly):

• Voltage - DC Reverse (Vr) (Max): 40 V
• Current - Average Rectified (Io): 30 mA
• Voltage - Forward (Vf) (Max) @ If: 370 mV @ 1 mA
• Current - Reverse Leakage @ Vr: 1 µA @ 40 V
• Capacitance @ Vr, F: 1.5 pF @ 1V, 1MHz

Mechanical Parameters (Must Match Exactly):

• Package / Case: 0503 (1308 Metric)
• Supplier Device Package: 0503/SOD-723F
• Mounting Type: Surface Mount

Technology Parameter (Must Match Exactly):

• Technology: Schottky

Substitute parts must satisfy all electrical, mechanical, and technology requirements without deviation. Packaging format (Tape & Reel versus other configurations) does not affect electrical or mechanical compatibility and does not preclude substitution.

Parameter Comparison

Engineering Selection Recommendations

The CDBER00340 (without the -HF suffix) is a direct parametric equivalent to the CDBER00340-HF. Both parts are manufactured by Comchip Technology and share identical electrical specifications, mechanical packaging, and operating characteristics.

The primary distinction between these parts is product status: CDBER00340-HF is classified as obsolete, while CDBER00340 maintains active product status. Both parts are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements.

For new designs or ongoing production requiring this diode specification, CDBER00340 is the appropriate selection due to its active status and continued availability. For legacy system maintenance where CDBER00340-HF was originally specified, CDBER00340 provides full electrical and mechanical compatibility without design modification.

Frequently Asked Questions (FAQ)

Q: Can CDBER00340 be used as a direct replacement for CDBER00340-HF?

A: Yes. Both parts are electrically and mechanically identical. They share the same 40V reverse voltage rating, 30mA average rectified current, forward voltage characteristics, reverse leakage specifications, and 0503/SOD-723F package configuration. The primary difference is product status classification.

Q: What is the significance of the -HF suffix?

A: The -HF suffix designation does not alter the electrical or mechanical parameters of the base part number CDBER00340. Both variants meet identical specifications for voltage, current, capacitance, and package requirements.

Q: Are there packaging format differences between these parts?

A: The main part (CDBER00340-HF) is supplied in standard packaging, while the substitute (CDBER00340) is available in Tape & Reel (TR) format. Both formats contain the same component with identical electrical and mechanical properties. Tape & Reel packaging is standard for surface mount production environments and does not affect component performance or compatibility.

Q: What compliance certifications apply to both parts?

A: Both CDBER00340-HF and CDBER00340 are ROHS3 compliant and REACH unaffected. Moisture Sensitivity Level is 1 (Unlimited) for both parts, indicating no moisture sensitivity restrictions during storage or handling.

Q: Why is CDBER00340-HF classified as obsolete?

A: Obsolete status indicates that the manufacturer has discontinued active production and support for this specific part designation. CDBER00340 remains in active production and is the recommended part number for current applications.
