10ETS08FP Equivalent & Substitute Parts

Part Overview

The 10ETS08FP is a general-purpose rectifier diode manufactured by Vishay General Semiconductor - Diodes Division, rated for 800 V DC reverse voltage and 10 A average rectified current in a through-hole TO-220AC Full Pack configuration. This part is classified as obsolete, making identification of equivalent and substitute components necessary for ongoing design support and procurement continuity. Equivalent parts maintain identical electrical and mechanical specifications, while substitute parts provide functional alternatives with modified parameters suitable for the same application class.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 10ETS08FP is determined by the following critical parameters: reverse voltage rating (Vr), average rectified current (Io), forward voltage drop (Vf), recovery speed classification, reverse leakage current, through-hole mounting compatibility, and TO-220 package form factor.

The identified substitute parts are grouped into two categories:

Parametric Equivalent (VS-10ETS08FP-M3): Maintains identical electrical specifications across all critical parameters—800 V reverse voltage, 10 A average rectified current, 1.1 V forward voltage drop at 10 A, standard recovery speed, and 50 µA reverse leakage at 800 V. The primary distinction is product status (active versus obsolete) and RoHS compliance (ROHS3 Compliant versus non-compliant), with packaging specified as tube format rather than full pack.

Manufacturer Recommended Substitute (STTH810FP): Provides functional substitution with modified electrical parameters. This STMicroelectronics device operates at 1000 V reverse voltage (200 V higher than the original), carries 8 A average rectified current (2 A lower than the original), exhibits 2 V forward voltage drop at 8 A (0.9 V higher than the original), and features fast recovery speed (≤500 ns versus >500 ns standard recovery). Reverse leakage is significantly lower at 5 µA @ 1000 V. This part is active, RoHS3 compliant, and rated to 175°C maximum junction temperature.

Engineering Selection Recommendations

For Direct Replacement (Parametric Equivalence): The VS-10ETS08FP-M3 is the appropriate selection when electrical specifications must remain unchanged. This part maintains 800 V reverse voltage, 10 A current rating, and identical forward voltage characteristics. The transition from obsolete to active product status ensures long-term availability. ROHS3 compliance satisfies modern regulatory requirements. Tube packaging is standard for active production inventory.

For Functional Substitution (Modified Parameters): The STTH810FP is suitable for applications where the circuit design accommodates higher reverse voltage (1000 V), reduced current capacity (8 A), and increased forward voltage drop (2 V @ 8 A). The fast recovery speed characteristic (85 ns trr) provides improved switching performance compared to standard recovery. Active product status and ROHS3 compliance ensure procurement continuity. The higher maximum junction temperature (175°C) extends thermal operating range. This part is appropriate for designs where the 10 A current requirement can be reduced to 8 A and where the additional forward voltage drop does not compromise circuit performance.

Compliance Considerations: Both substitute parts are ROHS3 compliant and REACH unaffected, addressing regulatory requirements absent in the obsolete original part. Selection between equivalents and substitutes should account for application-specific voltage, current, and thermal constraints.

Frequently Asked Questions (FAQ)

Q: Can VS-10ETS08FP-M3 be used as a direct replacement for 10ETS08FP?

A: Yes. The VS-10ETS08FP-M3 maintains identical electrical specifications: 800 V reverse voltage, 10 A average rectified current, 1.1 V forward voltage drop at 10 A, standard recovery speed, and 50 µA reverse leakage. Both parts use TO-220-2 Full Pack configuration. The primary differences are product status (active versus obsolete) and packaging format (tube versus full pack), neither of which affects electrical compatibility.

Q: What are the limitations of using STTH810FP as a substitute?

A: The STTH810FP introduces three parameter modifications: (1) reduced average rectified current from 10 A to 8 A, requiring circuit verification that load current does not exceed 8 A; (2) increased forward voltage drop from 1.1 V to 2 V at rated current, affecting power dissipation and thermal management; (3) higher reverse voltage rating (1000 V versus 800 V), which is not a limitation but provides additional margin. Fast recovery speed (85 ns) is an improvement over standard recovery. These modifications require circuit analysis to confirm suitability.

Q: Are there package compatibility issues between these parts?

A: All three parts use through-hole TO-220 package configuration suitable for PCB mounting. The 10ETS08FP and VS-10ETS08FP-M3 both specify TO-220-2 Full Pack. The STTH810FP specifies TO-220-2 Full Pack with isolated tab. Pin configuration and mounting footprint are compatible across all three parts for standard through-hole applications.

Q: What is the difference between "Full Pack" and "Tube" packaging?

A: Full Pack and Tube are inventory packaging formats that do not affect component electrical or mechanical specifications. Full Pack typically refers to bulk packaging for original stock, while Tube refers to standard reel or tube format for active production. Both formats contain identical components suitable for the same applications.

Q: Should I select the equivalent or substitute part?

A: Select VS-10ETS08FP-M3 (equivalent) if the circuit design requires 10 A current capacity and 800 V reverse voltage. Select STTH810FP (substitute) only if the application can operate with 8 A maximum current and can tolerate the increased forward voltage drop of 2 V. Verify circuit performance under the modified electrical parameters before selecting the substitute.

Q: Are both substitute parts RoHS compliant?

A: Yes. Both VS-10ETS08FP-M3 and STTH810FP are ROHS3 compliant. The original 10ETS08FP is RoHS non-compliant. Selection of either substitute part satisfies RoHS regulatory requirements.
