Substitute Part Grouping Explanation

Substitute parts for the MURA210T3 are classified into three categories based on electrical and mechanical compatibility:

Direct Manufacturer Equivalent (Packaging Variant): Parts that maintain identical electrical specifications and base product lineage but differ in packaging format or product status. These parts satisfy all critical parameters: 100 V reverse voltage, 2 A average rectified current, fast recovery speed classification, and SMA surface mount package.

Parametric Equivalent (Automotive Grade): Parts that match all electrical specifications and package requirements but include additional qualification standards such as AEC-Q101 automotive certification. These parts are suitable for applications requiring automotive-grade components while maintaining electrical compatibility.

Similar Parts (Reduced Current Rating): Parts that share the same 100 V reverse voltage rating and SMA package but operate at reduced current ratings (1 A instead of 2 A). These parts are suitable only for applications where the lower current rating is acceptable. Parts with different voltage ratings (600 V) or obsolete status are listed for reference but require design verification before substitution.

Key Parameters Determining Substitution:

Voltage - DC Reverse (Vr) (Max): Must equal 100 V
Current - Average Rectified (Io): Must equal or exceed 2 A for direct substitution
Package / Case: Must be DO-214AC, SMA
Mounting Type: Must be Surface Mount
Speed Classification: Fast Recovery preferred for performance consistency

Engineering Selection Recommendations

Primary Substitutes (Full Electrical and Mechanical Compatibility):

MURA210T3G (onsemi) is the direct successor to the obsolete MURA210T3. This part maintains identical electrical specifications including 100 V reverse voltage, 2 A average rectified current, 940 mV forward voltage at 2 A, and 30 ns reverse recovery time. The primary distinction is product status: MURA210T3G is active and ROHS3 compliant, whereas the original part is obsolete and RoHS non-compliant. This part is available in Cut Tape and Digi-Reel packaging formats with 10,100 pieces in stock.

NRVUA210VT3G-GA01 (onsemi) provides identical electrical performance to the MURA210T3 with the additional qualification of AEC-Q101 automotive certification. This part is suitable for applications requiring automotive-grade components. Product status is active with ROHS3 compliance. Inventory availability is 740 pieces.

VS-2EMH01-M3/5AT (Vishay General Semiconductor - Diodes Division) matches the 100 V, 2 A electrical specification with marginally improved reverse recovery time (25 ns versus 30 ns) and equivalent reverse leakage current (2 µA @ 100 V). This part is active, ROHS3 compliant, and available in Tape & Reel packaging with 23,182 pieces in stock.

Secondary Substitutes (Electrical Compatibility with Parameter Variations):

ES2BA-13-F (Diodes Incorporated) maintains 100 V reverse voltage and 2 A current rating with improved reverse recovery time (25 ns) and lower forward voltage (920 mV @ 2 A). However, reverse leakage current is elevated to 5 µA @ 100 V. Operating temperature range is -55°C to 150°C, which is narrower than the original part. This part is active and ROHS3 compliant with 34,605 pieces in stock.

ES2B-LTP (Micro Commercial Co) provides 100 V, 2 A electrical compatibility but is designated "Not For New Designs" and exhibits higher reverse leakage current (5 µA @ 100 V) and longer reverse recovery time (35 ns). This part should be used only when other options are unavailable.

Limited Substitutes (Reduced Current Rating):

US1B-13-F and S1B-13-F (Diodes Incorporated) are rated for 100 V reverse voltage but with reduced current capacity of 1 A instead of 2 A. These parts are suitable only for applications where the lower current rating is acceptable. US1B-13-F offers fast recovery characteristics (50 ns), while S1B-13-F exhibits standard recovery characteristics (3 µs).

Not Recommended for Direct Substitution:

US1J-13-F (Diodes Incorporated) operates at 600 V reverse voltage, which exceeds the original specification. This part is not suitable for direct substitution without circuit redesign verification.

Frequently Asked Questions (FAQ)

Q: Can MURA210T3G be used as a direct replacement for MURA210T3?

A: Yes. MURA210T3G is the active equivalent of the obsolete MURA210T3. Both parts share identical electrical specifications: 100 V reverse voltage, 2 A average rectified current, 940 mV forward voltage at 2 A, and 30 ns reverse recovery time. The primary difference is product status and RoHS compliance. MURA210T3G is recommended for new designs and ongoing production.

Q: What is the difference between MURA210T3G and NRVUA210VT3G-GA01?

A: Both parts are manufactured by onsemi and provide identical electrical performance. NRVUA210VT3G-GA01 includes AEC-Q101 automotive qualification, making it suitable for automotive applications. If automotive certification is not required, MURA210T3G is the standard choice. If automotive-grade components are specified, NRVUA210VT3G-GA01 is the appropriate selection.

Q: Can ES2BA-13-F replace MURA210T3 in all applications?

A: ES2BA-13-F maintains the 100 V reverse voltage and 2 A current rating but exhibits different electrical characteristics: forward voltage is lower (920 mV @ 2 A versus 940 mV), reverse recovery time is faster (25 ns versus 30 ns), and reverse leakage current is higher (5 µA @ 100 V versus 2 µA). Additionally, the operating temperature range is narrower (-55°C to 150°C versus -65°C to 175°C). Substitution is acceptable for applications where these parameter variations are within design tolerances.

Q: Why are US1B-13-F and S1B-13-F listed as similar parts if they have different current ratings?

A: These parts are listed for reference because they share the same 100 V reverse voltage rating and SMA package. However, the 1 A current rating is insufficient for applications requiring 2 A. These parts are suitable only for lower-current applications or as substitutes in circuits where the current demand does not exceed 1 A.

Q: Is VS-2EMH01-M3/5AT compatible with MURA210T3?

A: Yes. VS-2EMH01-M3/5AT is compatible with MURA210T3. Both parts are rated for 100 V reverse voltage and 2 A average rectified current. VS-2EMH01-M3/5AT offers slightly improved reverse recovery time (25 ns versus 30 ns) and maintains equivalent reverse leakage current (2 µA @ 100 V). This part is manufactured by Vishay and is active with ROHS3 compliance.

Q: What packaging formats are available for substitute parts?

A: Substitute parts are available in multiple packaging formats: Cut Tape (CT), Digi-Reel, and Tape & Reel (TR). MURA210T3G is available in Cut Tape and Digi-Reel formats. VS-2EMH01-M3/5AT is supplied in Tape & Reel format. ES2BA-13-F is available in Cut Tape and Digi-Reel formats. Packaging selection depends on production requirements and handling equipment compatibility.

Q: Should I use US1J-13-F as a substitute for MURA210T3?

A: No. US1J-13-F operates at 600 V reverse voltage, which significantly exceeds the 100 V specification of MURA210T3. While this part is in the same package, the voltage rating difference makes it unsuitable for direct substitution. Using a higher-voltage diode in a 100 V application introduces unnecessary cost and may affect circuit performance characteristics.

Q: What is the significance of RoHS compliance for substitute selection?

A: RoHS compliance indicates that the component meets Restriction of Hazardous Substances regulations. MURA210T3 is RoHS non-compliant, while all active substitute parts (MURA210T3G, NRVUA210VT3G-GA01, VS-2EMH01-M3/5AT, ES2BA-13-F, US1B-13-F, S1B-13-F, US1J-13-F) are ROHS3 compliant. For new designs and applications subject to RoHS requirements, compliant substitutes are mandatory.

Q: Can I use ES2B-LTP for new production?

A: ES2B-LTP is designated "Not For New Designs," indicating that the manufacturer recommends against using this part in new applications. While it provides 100 V, 2 A electrical compatibility, it should be reserved for legacy system support or repair applications only. For new production, use MURA210T3G, NRVUA210VT3G-GA01, VS-2EMH01-M3/5AT, or ES2BA-13-F instead.
