ACDBZ2240-HF Equivalent & Substitute Parts

Part Overview

The ACDBZ2240-HF is a Schottky rectifier diode manufactured by Comchip Technology, rated for 40 V DC reverse voltage and 2 A average rectified current in a surface mount Z2PAK package. This component is classified as obsolete, necessitating identification of active equivalent alternatives for ongoing production and maintenance applications. Substitute parts must maintain identical electrical performance and mechanical compatibility within the specified parameter envelope.

Substitute Part Grouping Explanation

Substitution of the ACDBZ2240-HF is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute parts CD214A-B240R and CD214B-B240R are classified as parametric equivalents because they satisfy the following criteria:

Electrical Parameter Equivalence:

• Identical reverse voltage rating: 40 V DC
• Identical average rectified current: 2 A
• Identical forward voltage drop: 500 mV @ 2 A
• Identical fast recovery speed specification: ≤ 500ns, > 200mA (Io)
• Identical reverse leakage current: 200 µA @ 40 V
• Identical junction capacitance: 115 pF @ 4V, 1MHz

Mechanical & Environmental Equivalence:

• Identical mounting type: Surface Mount
• Identical package configuration: 2-SMD, No Lead
• Identical operating temperature range: -55°C to 125°C
• Identical RoHS3 compliance status
• Identical MSL rating: 1 (Unlimited)

Functional Equivalence:

• All parts employ Schottky diode technology
• All parts function as fast recovery rectifiers in identical circuit applications

The two substitute parts differ only in packaging format (Cut Tape & Digi-Reel® versus Tape & Reel) and product status (both active), not in electrical or mechanical performance.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection Criteria:

Both CD214A-B240R and CD214B-B240R are active products manufactured by Bourns Inc. and provide complete electrical and mechanical equivalence to the obsolete ACDBZ2240-HF. Selection between the two substitute parts is determined by procurement and supply chain requirements rather than technical performance.

CD214A-B240R Selection:

• Recommended for applications requiring Cut Tape or Digi-Reel® packaging formats
• Suitable for lower-volume production runs or component-level procurement
• Higher inventory availability (41,822 pcs in stock)

CD214B-B240R Selection:

• Recommended for high-volume production requiring Tape & Reel (TR) packaging
• Suitable for automated assembly line integration
• Lower current inventory (632 pcs in stock)

Compliance Assurance: Both substitute parts maintain ROHS3 compliance and MSL 1 (Unlimited) rating, ensuring compatibility with environmental and reliability standards applicable to the original ACDBZ2240-HF. Both parts carry identical ECCN (EAR99) and HTSUS (8541.10.0080) classifications.

Frequently Asked Questions (FAQ)

Q: Can CD214A-B240R and CD214B-B240R be used interchangeably with ACDBZ2240-HF?

A: Yes. Both substitute parts are parametric equivalents with identical electrical specifications (40 V reverse voltage, 2 A current rating, 500 mV forward voltage drop, fast recovery speed, reverse leakage current, and junction capacitance) and identical mechanical specifications (surface mount, 2-SMD no-lead package, -55°C to 125°C operating range). The only difference is packaging format.

Q: What is the difference between CD214A-B240R and CD214B-B240R?

A: The electrical and mechanical specifications are identical. The difference is packaging format: CD214A-B240R is supplied in Cut Tape (CT) & Digi-Reel® format, while CD214B-B240R is supplied in Tape & Reel (TR) format. Selection depends on procurement method and assembly process requirements.

Q: Are there any compliance or certification differences between the main part and substitutes?

A: No. All three parts are ROHS3 compliant, carry MSL 1 (Unlimited) rating, and share identical ECCN and HTSUS classifications. The substitute parts are REACH Affected, whereas the main part is REACH Unaffected; however, this does not affect functional equivalence or substitution suitability.

Q: Can these parts be soldered using the same reflow profile?

A: Yes. All parts share identical MSL 1 (Unlimited) rating and surface mount configuration, indicating compatibility with standard reflow soldering processes. No process modification is required when substituting ACDBZ2240-HF with either CD214A-B240R or CD214B-B240R.

Q: Is the Z2PAK package equivalent to the 2-SMD package?

A: The ACDBZ2240-HF uses Z2PAK supplier device package designation, while the substitute parts use 2-SMD supplier device package designation. Both designations refer to the same 2-SMD, No Lead physical package configuration. The parts are mechanically and electrically compatible.

Q: Why is ACDBZ2240-HF classified as obsolete?

A: Product status reflects manufacturer discontinuation. The active substitute parts CD214A-B240R and CD214B-B240R provide identical performance and are recommended for all new designs and ongoing production requiring 40 V, 2 A Schottky rectifier diodes in surface mount configuration.
