Equivalent & Substitute Parts for 2A07G-T

Part Overview

The 2A07G-T is a general-purpose rectifier diode manufactured by Diodes Incorporated, rated for 1000 V DC reverse voltage and 2 A average rectified current in a DO-15 (DO-204AC) axial through-hole package. This component is classified as obsolete, which necessitates identification of active equivalent and substitute parts for ongoing design and procurement requirements. Equivalent parts maintain identical electrical and mechanical specifications, while substitute parts provide functional alternatives within the same application category with allowable parameter variations.

Substitute Part Grouping Explanation

Substitution of the 2A07G-T is determined by the following critical parameters: voltage rating (1000 V minimum), current rating (2 A minimum), package type (through-hole axial configuration), and technology classification (standard or fast recovery). The substitute parts identified fall into three functional categories:

Category 1: Direct Package Equivalents (DO-15/DO-204AC) Parts maintaining the identical DO-15 package footprint with matching voltage and current ratings. These include GPP20M-E3/54, 2A07G B0G, HER208G-AP, and HER208G-TP.

Category 2: Alternative Axial Package (DO-41/SOD-57) Parts with equivalent electrical ratings but different axial package geometries. These include MUR2100EG, MUR2100ERLG, and BYW56-TR, which maintain through-hole mounting compatibility with different physical dimensions.

Category 3: Technology Variants Parts with enhanced recovery characteristics (fast recovery ≤500ns) or avalanche technology, providing improved performance in specific circuit applications while maintaining core voltage and current specifications.

Substitution is valid when the substitute part meets or exceeds the minimum voltage (1000 V), current (2 A), and temperature range requirements of the original design, and maintains through-hole mounting compatibility.

Engineering Selection Recommendations

For Direct Replacement (Identical Package and Performance): GPP20M-E3/54 and 2A07G B0G are primary selections for direct substitution. Both maintain DO-15 package compatibility and standard recovery characteristics. GPP20M-E3/54 offers superior inventory availability (42,558 units) and active product status from Vishay General Semiconductor. 2A07G B0G provides lower forward voltage (1 V @ 2 A) and is available from Taiwan Semiconductor Corporation with 1,039 units in stock.

For Enhanced Performance Applications: HER208G-AP and HER208G-TP provide fast recovery characteristics (≤500ns, 75 ns trr) while maintaining DO-15 package compatibility. These parts are suitable for applications requiring reduced reverse recovery time. HER208G-TP offers higher inventory (29,729 units) in cut tape packaging.

For Alternative Package Geometries: MUR2100ERLG and MUR2100EG (onsemi SWITCHMODE™ series) provide DO-41 axial package alternatives with fast recovery performance. MUR2100ERLG offers the highest inventory availability (55,100 units) and maintains the full temperature range (-65°C ~ 175°C) of the original part.

For Avalanche Technology: BYW56-TR (Vishay) provides avalanche diode technology in SOD-57 package with standard recovery characteristics and extended temperature range (-55°C ~ 175°C). This part is suitable for applications requiring avalanche protection.

All recommended substitutes are ROHS3 compliant and carry active product status, ensuring long-term availability and supply chain stability.

Frequently Asked Questions (FAQ)

Q: Can GPP20M-E3/54 directly replace 2A07G-T without circuit modification? A: Yes. GPP20M-E3/54 maintains identical voltage (1000 V), current (2 A), and forward voltage (1.1 V @ 2 A) specifications with standard recovery characteristics. The DO-15 package footprint is identical. Operating temperature range is reduced (-55°C ~ 150°C versus -65°C ~ 175°C), which must be verified against application requirements.

Q: What is the difference between standard and fast recovery diodes in this category? A: Standard recovery diodes (2A07G-T, GPP20M-E3/54) have recovery times >500ns. Fast recovery diodes (HER208G series, MUR2100 series) have recovery times ≤500ns. Fast recovery reduces switching losses in high-frequency applications but typically exhibits higher forward voltage drop.

Q: Are HER208G-AP and HER208G-TP interchangeable? A: Electrically, yes. Both parts are identical in voltage, current, and recovery characteristics. The difference is packaging: HER208G-AP is supplied in Tape & Box (TB) format, while HER208G-TP is supplied in Cut Tape (CT) format. Selection depends on procurement and assembly requirements.

Q: Can MUR2100ERLG replace 2A07G-T in a DO-15 footprint? A: No. MUR2100ERLG uses DO-41 axial package, which has different physical dimensions than DO-15. While electrically compatible, PCB layout and mechanical mounting must accommodate the different package geometry. This substitution requires circuit board redesign.

Q: What is the impact of forward voltage differences between substitute parts? A: Forward voltage variations (1.0 V to 2.2 V @ 2 A) affect power dissipation and voltage drop across the diode. Higher forward voltage increases heat generation. Circuit designs with tight voltage margin specifications must account for these differences. Thermal management and voltage regulation may require adjustment.

Q: Are all substitute parts RoHS3 compliant? A: Yes. All identified substitute parts carry ROHS3 Compliant status, ensuring compatibility with environmental and regulatory requirements equivalent to the original 2A07G-T.

Q: Which substitute offers the best long-term availability? A: MUR2100ERLG (onsemi) offers the highest inventory (55,100 units) and active product status with established supply chain presence. GPP20M-E3/54 (Vishay) provides the second-highest availability (42,558 units) with active status.
