BAT42WS Equivalent & Substitute Parts

Part Overview

The BAT42WS is a Schottky diode manufactured by Taiwan Semiconductor Corporation, designed for surface mount applications in the SOD-323F package. This component operates at 30V reverse voltage with a 200mA average rectified current rating. The BAT42WS is discontinued at DiGi Electronics, necessitating identification of functionally equivalent alternatives for ongoing design requirements and procurement needs.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the BAT42WS is determined by electrical and mechanical parameter equivalence. The following criteria establish functional interchangeability:

Electrical Parameters:

• Voltage - DC Reverse (Vr) (Max): 30 V
• Current - Average Rectified (Io): 200 mA
• Voltage - Forward (Vf) (Max) @ If: 1 V @ 200 mA
• Reverse Recovery Time (trr): 5 ns
• Current - Reverse Leakage @ Vr: 500 nA @ 25 V
• Capacitance @ Vr, F: 7 pF @ 1V, 1MHz

Mechanical Parameters:

• Package / Case: SC-90, SOD-323F
• Mounting Type: Surface Mount
• Operating Temperature - Junction: -65°C to 125°C

Compliance Parameters:

• Technology: Schottky
• RoHS Status: ROHS3 Compliant
• REACH Status: REACH Unaffected

Substitute parts must match all electrical specifications, maintain identical package geometry, and satisfy the same regulatory compliance requirements.

Parameter Comparison

Engineering Selection Recommendations

The BAT42WS RRG is a direct electrical and mechanical equivalent to the BAT42WS. Both components are manufactured by Taiwan Semiconductor Corporation and share identical electrical specifications across all rated parameters. The primary distinction is product status and packaging format.

BAT42WS RRG Selection Basis:

The BAT42WS RRG maintains active product status, ensuring continued availability and supply chain reliability. This substitute part is supplied in Tape & Reel (TR) packaging, which is standard for high-volume manufacturing and automated assembly processes. Both parts satisfy ROHS3 compliance and REACH regulatory requirements, supporting equivalent environmental and safety standards.

All electrical parameters—including reverse voltage rating, forward voltage drop, reverse recovery time, reverse leakage current, and junction capacitance—are identical between the two parts. The SOD-323F package geometry and surface mount mounting type are preserved, enabling direct substitution in existing PCB designs without layout modifications.

Frequently Asked Questions (FAQ)

Q: Can BAT42WS RRG replace BAT42WS in existing designs?

A: Yes. The BAT42WS RRG is electrically and mechanically equivalent to the BAT42WS. All electrical specifications, package dimensions, and operating temperature ranges are identical. Direct substitution is supported without design changes.

Q: What is the difference between BAT42WS and BAT42WS RRG?

A: The primary differences are product status and packaging format. The BAT42WS is discontinued and supplied in bulk packaging. The BAT42WS RRG is an active product supplied in Tape & Reel (TR) format, which is standard for automated assembly and high-volume production.

Q: Are there any compliance differences between these parts?

A: No. Both parts are ROHS3 compliant and REACH unaffected. They satisfy identical regulatory requirements and environmental standards.

Q: Does the Tape & Reel packaging affect electrical performance?

A: No. Packaging format does not affect electrical characteristics. The Tape & Reel format is a supply and handling specification only. Electrical performance remains identical to bulk-packaged components.

Q: What are the critical parameters for substitution?

A: Substitution is determined by matching voltage rating (30V), current rating (200mA), forward voltage drop (1V @ 200mA), reverse recovery time (5ns), reverse leakage current (500nA @ 25V), capacitance (7pF @ 1V, 1MHz), package type (SOD-323F), and operating temperature range (-65°C to 125°C).

Q: Can BAT42WS be used in applications requiring Tape & Reel packaging?

A: The BAT42WS is discontinued and may not be available in Tape & Reel format. The BAT42WS RRG is the recommended alternative for applications requiring TR packaging for automated assembly.
