CD214A-F1400 Equivalent & Substitute Parts

Part Overview

The CD214A-F1400 is a general-purpose rectifier diode manufactured by Bourns Inc., rated for 400 V DC reverse voltage and 1 A average rectified current in a DO-214AC (SMA) surface mount package. This part is classified as obsolete, making equivalent and substitute parts necessary for ongoing production and design continuity. The diode features fast recovery characteristics with a reverse recovery time of 25 ns and operates across a junction temperature range of -55°C to 150°C. Substitution is required to maintain supply chain availability and support active production environments.

Substitute Part Grouping Explanation

Substitution of the CD214A-F1400 is determined by the following critical parameters:

Electrical Compatibility Requirements:

Voltage - DC Reverse (Vr) (Max): 400 V minimum
Current - Average Rectified (Io): 1 A minimum
Voltage - Forward (Vf) (Max) @ If: 1.25 V or lower at rated current
Technology: Standard rectifier diode technology

Mechanical Compatibility Requirements:

Mounting Type: Surface Mount
Package / Case: DO-214AC (SMA) or equivalent footprint-compatible packages (DO-214BA)
Operating Temperature Range: Must encompass or exceed -55°C to 150°C

Regulatory & Compliance Requirements:

RoHS3 Compliance: Required
REACH Status: Affected or Unaffected acceptable
Moisture Sensitivity Level (MSL): 1 (Unlimited)

Substitute parts are grouped into two categories: Direct Package Equivalents (DO-214AC/SMA package) and Package-Compatible Alternatives (DO-214BA package with identical electrical performance). Recovery speed characteristics (Fast Recovery ≤500 ns or Standard Recovery >500 ns) are secondary considerations and do not preclude substitution when primary electrical and mechanical parameters align.

Engineering Selection Recommendations

Primary Substitutes (Active Product Status):

For applications requiring active, production-supported components, the following substitutes are recommended based on electrical equivalence and current product status:

ES1G-LTP (Micro Commercial Co): Maintains identical electrical specifications to the CD214A-F1400 with 1.25 V forward voltage at 1 A, fast recovery characteristics (35 ns), and extended operating temperature range (-65°C to 175°C). Active product status ensures long-term availability.
CGRA4004-G (Comchip Technology): Provides 400 V / 1 A rating with improved forward voltage (1.1 V @ 1 A) in DO-214AC package. Active product status supports production continuity.
GF1G-E3/5CA and GF1G-E3/67A (Vishay General Semiconductor - Diodes Division): Both are active products rated 400 V / 1 A with 1.1 V forward voltage. These parts use DO-214BA package, which is mechanically compatible with DO-214AC footprints in most PCB designs. Extended temperature range (-65°C to 175°C) provides operational margin.

Secondary Substitutes (Not For New Designs Status):

The following parts meet electrical and mechanical requirements but carry "Not For New Designs" status. These are suitable for legacy system maintenance and repair:

GF1G (onsemi): 400 V / 1 A with 1.0 V forward voltage in DO-214AC package.
GS1G-LTP (Micro Commercial Co): 400 V / 1 A with 1.0 V forward voltage in DO-214AC package.
GS1GE-TP (Micro Commercial Co): 400 V / 1 A with 1.1 V forward voltage in DO-214AC package.
MRA4004T3G (onsemi): 400 V / 1 A with 1.1 V forward voltage in DO-214AC package.

Alternative Substitute (Different Package):

CD214A-FS1G (Bourns Inc.): Same manufacturer as the original part, rated 400 V / 1 A with 1.25 V forward voltage. Uses 2-SMD package instead of DO-214AC, requiring PCB layout modification. Active product status ensures availability.

All recommended substitutes are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity rating, matching the original part's regulatory profile.

Frequently Asked Questions (FAQ)

Q: Can I substitute the CD214A-F1400 with any 400 V / 1 A diode?

A: No. Substitution requires matching the following parameters: 400 V DC reverse voltage rating, 1 A average rectified current, forward voltage not exceeding 1.25 V at 1 A, surface mount technology, and DO-214AC (SMA) or compatible package. Additionally, the substitute must be ROHS3 compliant with MSL 1 rating.

Q: What is the difference between DO-214AC and DO-214BA packages?

A: DO-214AC (SMA) and DO-214BA (GF1) are both surface mount packages with different physical dimensions and lead configurations. DO-214BA is mechanically compatible with DO-214AC footprints in most applications, though PCB layout verification is required. Both packages are suitable for the CD214A-F1400 application.

Q: Does recovery speed affect substitution compatibility?

A: Recovery speed (measured as reverse recovery time, trr) is a secondary parameter. The CD214A-F1400 features fast recovery (25 ns), while some substitutes have standard recovery characteristics (>500 ns or 2 µs). Both recovery types are electrically compatible for general-purpose rectification applications. Application-specific requirements may necessitate fast recovery characteristics; consult circuit design specifications.

Q: Why is the CD214A-F1400 marked as obsolete?

A: Obsolete status indicates the part is no longer manufactured by Bourns Inc. and existing inventory is limited. Substitution with active-status alternatives ensures long-term supply chain reliability and production continuity.

Q: Can I use a substitute with a lower forward voltage?

A: Yes. Substitutes with forward voltage lower than 1.25 V (such as CGRA4004-G at 1.1 V or GF1G at 1.0 V) are electrically compatible and may provide improved efficiency due to reduced power dissipation. No circuit modification is required.

Q: Are all listed substitutes ROHS3 compliant?

A: Yes. All substitute parts listed in this document are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity rating, matching the regulatory profile of the CD214A-F1400.

Q: What is the difference between "Active" and "Not For New Designs" product status?

A: "Active" status indicates the manufacturer continues production and supports the part for new designs. "Not For New Designs" status indicates the part is in production but the manufacturer does not recommend it for new circuit designs; however, it remains suitable for legacy system maintenance and repair. For new designs, prioritize active-status substitutes.

Q: Can I substitute the CD214A-F1400 with the CD214A-FS1G?

A: Yes, electrically. Both are Bourns Inc. products with identical 400 V / 1 A / 1.25 V specifications. However, CD214A-FS1G uses a 2-SMD package instead of DO-214AC, requiring PCB layout modification. CD214A-FS1G is active status, ensuring long-term availability.

Q: Which substitute offers the best long-term availability?

A: ES1G-LTP (Micro Commercial Co) and CGRA4004-G (Comchip Technology) are both active-status products with high inventory levels (13,565 and 20,100 units respectively) and identical or superior electrical specifications. Both are recommended for new production designs requiring supply chain security.
