BAV21WHE3-TP Equivalent & Substitute Parts

Part Overview

The BAV21WHE3-TP is a general-purpose rectifier diode manufactured by Micro Commercial Co, rated for 200V DC reverse voltage and 200mA average rectified current in a surface mount SOD-123 package. This component is classified as a small signal diode with standard switching speed characteristics and is actively produced. The part is supplied in Cut Tape (CT) & Digi-Reel® packaging format.

Substitute parts are identified when equivalent electrical performance and mechanical compatibility are maintained across the specified parameter set. Packaging format differences may necessitate alternative part selection for specific manufacturing or procurement workflows.

Substitute Part Grouping Explanation

Substitute parts for the BAV21WHE3-TP are identified based on strict electrical and mechanical parameter equivalence. The following criteria determine substitution eligibility:

Electrical Parameters (Must Match):

• Voltage - DC Reverse (Vr) (Max): 200 V
• Current - Average Rectified (Io): 200 mA
• Voltage - Forward (Vf) (Max) @ If: 1.25 V @ 200 mA
• Reverse Recovery Time (trr): 50 ns
• Current - Reverse Leakage @ Vr: 100 nA @ 200 V
• Capacitance @ Vr, F: 1.5 pF @ 0V, 1MHz
• Operating Temperature - Junction: -55°C to 150°C

Mechanical Parameters (Must Match):

• Package / Case: SOD-123
• Mounting Type: Surface Mount

Compliance Parameters (Must Match):

• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

Packaging format (Cut Tape & Digi-Reel® versus Tape & Reel) represents a supply chain variation and does not affect electrical or mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

The BAV21W-TP is a direct electrical and mechanical equivalent to the BAV21WHE3-TP. Both parts are manufactured by Micro Commercial Co, share identical electrical specifications, and are housed in the same SOD-123 surface mount package. Both parts maintain active product status and comply with ROHS3 and moisture sensitivity requirements.

The primary distinction between these parts is packaging format. The BAV21WHE3-TP is supplied in Cut Tape (CT) & Digi-Reel® format, while the BAV21W-TP is supplied in Tape & Reel (TR) format. This difference reflects supply chain and manufacturing process variations and does not affect component performance or circuit functionality.

Selection between these parts should be based on procurement requirements, manufacturing equipment compatibility, and inventory management practices specific to the application workflow.

Frequently Asked Questions (FAQ)

Q: Can BAV21W-TP be used as a direct replacement for BAV21WHE3-TP in circuit design?

A: Yes. Both parts are electrically and mechanically identical. All electrical parameters, including reverse voltage rating, forward current capacity, forward voltage drop, reverse recovery time, and leakage current are equivalent. Both are packaged in SOD-123 surface mount format and operate across the same temperature range.

Q: What is the difference between Cut Tape (CT) & Digi-Reel® and Tape & Reel (TR) packaging?

A: These represent different supply formats for the same component. Cut Tape & Digi-Reel® provides flexibility for smaller quantity orders and manual assembly processes. Tape & Reel format is optimized for high-volume automated assembly lines. The physical component and electrical performance remain unchanged.

Q: Are both parts suitable for automotive applications?

A: The BAV21WHE3-TP carries automotive grade qualification (AEC-Q101). The BAV21W-TP specifications provided do not explicitly list automotive qualification status. Verify automotive compliance requirements with the manufacturer if this is a critical application parameter.

Q: Do these parts require special handling or storage conditions?

A: Both parts carry Moisture Sensitivity Level (MSL) 1, which indicates unlimited shelf life and no special moisture control requirements during storage or handling.

Q: Can these diodes be used interchangeably in high-frequency switching applications?

A: Both parts have identical reverse recovery time (50 ns) and capacitance specifications (1.5 pF @ 0V, 1MHz). They are classified as small signal diodes with standard switching speed characteristics and are suitable for applications within their specified electrical ratings.
