Substitute Part Grouping Explanation

Substitution of the DA2JF8100L is determined by matching the following critical electrical parameters: 800V DC reverse voltage rating, 200mA average rectified current capacity, surface mount configuration, and small signal diode speed classification. The substitute part RFU02VSM8STR meets these core electrical specifications while maintaining compatibility with the same voltage and current operating envelope. Both parts are classified as standard technology general-purpose rectifier diodes with unlimited moisture sensitivity level (MSL 1) and are suitable for identical application contexts.

The substitution is valid based on:

Identical DC reverse voltage rating (800 V)
Identical average rectified current (200 mA)
Identical reverse leakage current specification (10 µA @ 800 V)
Surface mount technology with compatible thermal and mechanical characteristics
Small signal diode speed classification
Equivalent RoHS compliance status

Engineering Selection Recommendations

The RFU02VSM8STR from Rohm Semiconductor is a direct functional substitute for the discontinued DA2JF8100L. Both components share identical voltage and current ratings, making them electrically interchangeable for applications requiring 800V/200mA rectification. The RFU02VSM8STR offers the advantage of active product status with current availability, whereas the DA2JF8100L is discontinued.

The RFU02VSM8STR exhibits superior reverse recovery time performance (25 ns versus 45 ns), which provides faster switching characteristics. The forward voltage specification of the RFU02VSM8STR is 0.5V higher at maximum rating (3V versus 2.5V at 200mA), which should be evaluated in applications with tight forward voltage budgets. The RFU02VSM8STR demonstrates higher junction capacitance (4pF versus 0.6pF), a consideration for high-frequency applications.

Both parts maintain equivalent RoHS compliance status and unlimited moisture sensitivity level, ensuring compatibility with modern manufacturing and environmental standards. The RFU02VSM8STR is available in Cut Tape and Digi-Reel packaging formats, supporting both prototype and production volume requirements.

Frequently Asked Questions (FAQ)

Q: Can the RFU02VSM8STR directly replace the DA2JF8100L in existing designs?

A: Yes. Both components share identical voltage (800V) and current (200mA) ratings, reverse leakage current specifications, and operating temperature ranges. The electrical performance envelope is compatible for standard rectification applications.

Q: What are the differences in forward voltage between these parts?

A: The DA2JF8100L specifies 2.5V maximum forward voltage at 200mA, while the RFU02VSM8STR specifies 3V maximum at the same current. This 0.5V difference should be evaluated in power supply designs where forward voltage drop directly impacts efficiency or output regulation.

Q: How do the reverse recovery times differ?

A: The DA2JF8100L has a reverse recovery time of 45 nanoseconds, while the RFU02VSM8STR is specified at 25 nanoseconds. The faster recovery time of the RFU02VSM8STR reduces switching losses and may improve performance in high-frequency rectification circuits.

Q: Are the package configurations compatible?

A: The DA2JF8100L uses the SMini2-F5-B package (SC-90, SOD-323F), while the RFU02VSM8STR uses the TUMD2SM package (2-SMD, Flat Lead). Both are surface mount configurations with similar physical dimensions suitable for automated assembly. PCB layout compatibility should be confirmed based on specific footprint requirements.

Q: What is the significance of the capacitance difference?

A: The DA2JF8100L specifies 0.6pF junction capacitance at 0V and 1MHz, while the RFU02VSM8STR specifies 4pF under identical conditions. Higher capacitance may affect performance in high-frequency or high-impedance circuits. Applications operating above 1MHz should evaluate this parameter against circuit requirements.

Q: Are both parts RoHS compliant?

A: Yes. The DA2JF8100L is RoHS Compliant, and the RFU02VSM8STR is ROHS3 Compliant. Both meet current environmental and hazardous substance restrictions for electronic components.

Q: What is the moisture sensitivity level for these parts?

A: Both the DA2JF8100L and RFU02VSM8STR are classified as MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.
