Substitute Part Grouping Explanation

Substitute parts for the ES2J R5G are classified into two categories based on electrical and mechanical parameter alignment:

Parametric Equivalents maintain identical or functionally equivalent electrical specifications across all critical parameters: 600 V reverse voltage, 2 A average rectified current, 1.7 V forward voltage at 2 A, 35 ns reverse recovery time, 10 µA reverse leakage current, and DO-214AA (SMB) package. These parts differ only in packaging format (Cut Tape vs. Tape & Reel), product status (Active vs. Discontinued), or automotive qualification grades. Parametric equivalents include ES2J (Good-Ark Semiconductor), ES2JH, ES2LJ, and ES2LJH (all Taiwan Semiconductor Corporation).

Similar Parts share the same 600 V reverse voltage and 2 A current rating with DO-214AA (SMB) packaging but exhibit variations in one or more secondary electrical parameters such as forward voltage, reverse recovery time, reverse leakage current, or capacitance. These parts remain functionally suitable for applications where the primary voltage and current specifications are the controlling design factors. Similar parts include CSFB205-G (Comchip Technology), ER2J-LTP (Micro Commercial Co), and ER3JB-TP (Micro Commercial Co).

Engineering Selection Recommendations

Parametric Equivalent Selection (Preferred for Direct Replacement)

ES2J (Good-Ark Semiconductor) is the primary parametric equivalent, offering identical electrical specifications with active product status and availability in both Cut Tape and Digi-Reel® packaging formats. This part provides the most direct substitution path with 95,400 units in stock.

ES2JH and ES2LJH (Taiwan Semiconductor Corporation) are parametric equivalents qualified to AEC-Q101 automotive standards, suitable for applications requiring automotive-grade components. ES2JH provides 6,610 units in stock, while ES2LJH provides 7,044 units. Both are available in Tape & Reel packaging.

ES2LJ (Taiwan Semiconductor Corporation) is a parametric equivalent without automotive qualification, available in Tape & Reel format with 6,683 units in stock.

All parametric equivalents maintain RoHS3 compliance, MSL 1 rating, and REACH unaffected status identical to the ES2J R5G.

Similar Part Selection (Application-Dependent)

ER2J-LTP (Micro Commercial Co) matches the 600 V / 2 A specification with identical 35 ns reverse recovery time and forward voltage characteristics. This part exhibits lower reverse leakage current (5 µA vs. 10 µA) and reduced capacitance (15 pF vs. 20 pF), with extended operating temperature range (-65°C to 175°C). Inventory availability is substantial at 28,296 units.

CSFB205-G (Comchip Technology) provides 600 V / 2 A operation with improved forward voltage performance (1.3 V vs. 1.7 V at 2 A), resulting in lower power dissipation. Reverse recovery time and leakage current specifications are equivalent. This part is suitable for applications where forward voltage reduction is beneficial.

HS2J (Taiwan Semiconductor Corporation) maintains 600 V / 2 A ratings with extended reverse recovery time (75 ns vs. 35 ns) and reduced reverse leakage current (5 µA vs. 10 µA). This part is applicable where slower recovery characteristics are acceptable or beneficial.

ER3JB-TP (Micro Commercial Co) provides higher current capability (3 A vs. 2 A) at 600 V, suitable for applications requiring current margin or future design scaling.

Frequently Asked Questions (FAQ)

Q: Can ES2J (Good-Ark Semiconductor) directly replace ES2J R5G in existing designs?

A: Yes. ES2J from Good-Ark Semiconductor is a parametric equivalent with identical voltage (600 V), current (2 A), forward voltage (1.7 V @ 2 A), reverse recovery time (35 ns), reverse leakage current (10 µA @ 600 V), and capacitance (20 pF @ 4V, 1MHz) specifications. Both use DO-214AA (SMB) packaging. The primary difference is packaging format availability (Cut Tape & Digi-Reel® vs. Cut Tape only) and active product status.

Q: What is the difference between ES2JH and ES2LJ?

A: ES2JH and ES2LJ are both parametric equivalents of ES2J R5G with identical electrical specifications. ES2JH is qualified to AEC-Q101 automotive standards, while ES2LJ is not. Both are available in Tape & Reel packaging. Selection depends on automotive qualification requirements for the application.

Q: Can ER2J-LTP be used as a direct substitute?

A: ER2J-LTP is a similar part, not a parametric equivalent. It maintains the same 600 V reverse voltage and 2 A current rating with identical forward voltage (1.7 V @ 2 A) and reverse recovery time (35 ns). However, it exhibits lower reverse leakage current (5 µA vs. 10 µA) and reduced capacitance (15 pF vs. 20 pF). It is suitable for applications where these parameter variations are acceptable. The extended operating temperature range (-65°C to 175°C vs. -55°C to 150°C) provides additional thermal margin.

Q: Why would CSFB205-G be selected over parametric equivalents?

A: CSFB205-G offers improved forward voltage performance (1.3 V vs. 1.7 V at 2 A), resulting in reduced power dissipation and heat generation. This characteristic is beneficial in applications where thermal management or efficiency is a design constraint. All other critical parameters (600 V, 2 A, 35 ns recovery time, DO-214AA package) remain compatible.

Q: Is ER3JB-TP suitable for ES2J R5G replacement?

A: ER3JB-TP is a similar part with higher current rating (3 A vs. 2 A) at the same 600 V reverse voltage. It maintains identical forward voltage (1.7 V) and reverse recovery time (35 ns) characteristics. This part is suitable for applications where current margin is required or where design scaling to higher current levels is anticipated. The DO-214AA (SMB) package remains identical.

Q: What packaging format differences exist among substitute parts?

A: The ES2J R5G is supplied in Cut Tape (CT) format. Parametric equivalents are available in multiple packaging formats: ES2J (Good-Ark) offers both Cut Tape and Digi-Reel®; ES2JH, ES2LJ, and ES2LJH are supplied in Tape & Reel (TR) format. Similar parts (ER2J-LTP, CSFB205-G, ER3JB-TP) are also available in Tape & Reel format. Packaging selection depends on assembly equipment compatibility and procurement requirements.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All parametric equivalent and similar parts listed maintain RoHS3 compliance, MSL 1 (Unlimited) rating, and REACH unaffected status, matching the ES2J R5G environmental and regulatory compliance profile.

Q: What is the significance of AEC-Q101 qualification on ES2JH and ES2LJH?

A: AEC-Q101 qualification indicates that these parts meet automotive industry reliability and quality standards. ES2JH and ES2LJH are suitable for automotive applications requiring qualified component documentation. Non-qualified parametric equivalents (ES2J, ES2LJ) are suitable for general industrial and consumer applications.
