Substitute Part Grouping Explanation

Substitution between the 10ETF04FP and VS-10ETF04FP-M3 is established on the basis of matching electrical and mechanical parameters within the allowed tolerances for this diode category:

Matching Parameters:

• DC reverse voltage rating: 400 V (identical)
• Average rectified current: 10 A (identical)
• Forward voltage drop: 1.2 V @ 10 A (identical)
• Speed classification: Fast Recovery ≤ 500ns, > 200mA (identical)
• Mounting type: Through Hole (identical)
• Package classification: TO-220-2 Full Pack (identical)
• Operating temperature range: -40°C to 150°C (identical)
• Base product number: 10ETF04 (identical)

Acceptable Parameter Variations:

• Reverse recovery time: 145 ns (main part) versus 200 ns (substitute) — both within fast recovery classification
• Reverse leakage current measurement condition: 100 µA @ 400 V (main part) versus 100 µA @ 200 V (substitute) — leakage specification at lower voltage indicates equivalent or superior performance

Compliance Differences:

• Main part (10ETF04FP): RoHS non-compliant, obsolete status
• Substitute part (VS-10ETF04FP-M3): RoHS3 compliant, active product status

Parameter Comparison

Engineering Selection Recommendations

The VS-10ETF04FP-M3 is the direct functional equivalent for the obsolete 10ETF04FP. Selection of the substitute part is supported by the following engineering factors:

Electrical Equivalence: All critical electrical parameters match or exceed the original specification. The reverse recovery time of 200 ns in the substitute part remains within the fast recovery classification and is acceptable for applications designed for the 145 ns specification. The reverse leakage current measurement at 200 V in the substitute part indicates performance that meets or exceeds the 400 V specification of the original part.

Compliance Status: The VS-10ETF04FP-M3 carries RoHS3 compliance certification, addressing regulatory requirements that may apply to new designs or procurement cycles. The original 10ETF04FP is RoHS non-compliant and obsolete, making continued sourcing problematic for applications subject to environmental compliance mandates.

Product Availability: The substitute part maintains active product status with current inventory, ensuring long-term procurement viability. The original part is obsolete and subject to limited availability.

Mechanical Compatibility: Both parts use identical through-hole mounting in TO-220-2 Full Pack configuration, ensuring direct PCB footprint compatibility. Packaging format differs (Full Pack versus Tube), which affects handling and storage but not electrical or mechanical function.

Frequently Asked Questions (FAQ)

Q: Can VS-10ETF04FP-M3 be used as a direct replacement for 10ETF04FP in existing designs?

A: Yes. The substitute part meets all electrical specifications of the original component. Both parts share identical voltage ratings (400 V), current ratings (10 A), forward voltage characteristics (1.2 V @ 10 A), and operating temperature range (-40°C to 150°C). The through-hole TO-220-2 Full Pack configuration ensures PCB footprint compatibility.

Q: What is the significance of the different reverse recovery times (145 ns vs. 200 ns)?

A: Both parts are classified as fast recovery diodes with recovery times ≤ 500 ns. The 200 ns specification of the substitute part remains well within this classification and is functionally equivalent for applications designed for the original 145 ns specification. The difference does not affect circuit performance in standard rectification applications.

Q: Does the different reverse leakage current measurement condition affect substitution?

A: No. The substitute part specifies reverse leakage at 200 V, while the original specifies it at 400 V. Leakage current measured at lower voltage indicates performance that meets or exceeds the original specification at higher voltage. This represents an equivalent or superior characteristic.

Q: What is the impact of RoHS3 compliance on substitution?

A: RoHS3 compliance of the substitute part represents an upgrade from the non-compliant status of the original part. This is beneficial for applications subject to environmental regulations or procurement policies requiring RoHS compliance. No negative impact on electrical or mechanical function results from this compliance upgrade.

Q: Are there packaging differences between these parts?

A: Yes. The original 10ETF04FP uses Full Pack packaging, while the substitute VS-10ETF04FP-M3 uses Tube packaging. Both contain identical electrical components in the same TO-220-2 Full Pack case style. The packaging difference affects handling, storage, and quantity per container but does not affect electrical performance or PCB mounting.

Q: Is the substitute part suitable for new designs?

A: Yes. The VS-10ETF04FP-M3 is an active product with current inventory and RoHS3 compliance, making it the appropriate choice for new designs requiring a 400 V, 10 A general-purpose rectifier diode in through-hole TO-220-2 configuration.
