CR3F-020 TR Equivalent & Substitute Parts

Part Overview

The CR3F-020 TR is a general-purpose rectifier diode manufactured by Central Semiconductor Corp, rated for 200 V DC reverse voltage and 3 A average rectified current in a DO-201 through-hole axial package. This part is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and procurement continuity. Substitute parts must maintain electrical compatibility across voltage, current, and thermal specifications while accommodating available packaging options.

Substitute Part Grouping Explanation

Substitute parts for the CR3F-020 TR are selected based on strict electrical and mechanical parameter matching. The primary substitution criteria are:

Mandatory Matching Parameters:

Voltage - DC Reverse (Vr) (Max): 200 V
Current - Average Rectified (Io): 3 A minimum
Mounting Type: Through Hole
Package / Case: DO-201 or DO-201AD axial configuration

Secondary Compatibility Factors:

Reverse Recovery Time (trr): Fast Recovery (≤500 ns) or Standard Recovery (>500 ns)
Voltage - Forward (Vf) (Max) @ If: 1.0 to 1.3 V @ rated current
Current - Reverse Leakage @ Vr: ≤10 µA @ 200 V
Operating Temperature Range: Must encompass or exceed -55°C to 125°C

Substitute parts are grouped by recovery speed classification and current rating. Parts with higher current ratings (4 A) are acceptable substitutes provided all other parameters remain within specification. Packaging variants (Tape & Reel vs. Cut Tape) do not affect electrical compatibility.

Engineering Selection Recommendations

RGP30D-E3/54 and RGP30D-E3/73 (Vishay SUPERECTIFIER® Series)

These parts provide direct electrical equivalence to the CR3F-020 TR with identical voltage, current, and recovery time specifications. Both are active products with ROHS3 compliance and extended operating temperature range (-65°C to 175°C). The primary difference is packaging format: RGP30D-E3/54 is supplied in Tape & Reel configuration, while RGP30D-E3/73 is supplied in Cut Tape. Both use the DO-201AD package variant. Selection between these two depends on assembly process requirements rather than electrical performance.

1N5402-E3/54 and 1N5402-E3/73 (Vishay Standard Recovery)

These parts meet the 200 V / 3 A electrical requirements with forward voltage matching the original CR3F-020 TR specification (1.2 V @ 3 A). Recovery time is classified as standard (>500 ns) rather than fast recovery. Operating temperature range is -50°C to 150°C, which encompasses the original part's minimum junction temperature. Both are active products with ROHS3 compliance. Selection between /54 and /73 variants depends on packaging format preference.

MUR420GP-TP (Micro Commercial Co)

This part exceeds the original specification with 4 A current rating and superior fast recovery characteristics (60 ns trr). Forward voltage is lower (1.0 V @ 4 A), providing improved efficiency. Operating temperature range is -55°C to 150°C. This part is suitable for applications requiring enhanced performance margin or where the higher current rating provides system-level benefits. Supplied in Tape & Reel format.

Selection Criteria:

For direct replacement with identical specifications: RGP30D-E3/54 or RGP30D-E3/73
For standard recovery applications with cost optimization: 1N5402-E3/54 or 1N5402-E3/73
For enhanced performance and efficiency: MUR420GP-TP

All substitute parts are active products with current manufacturing support and compliance certifications (ROHS3, REACH Unaffected, EAR99).

Frequently Asked Questions (FAQ)

Q: Can RGP30D-E3/54 and RGP30D-E3/73 be used interchangeably with CR3F-020 TR?

A: Yes. Both parts have identical electrical specifications (200 V, 3 A, 150 ns recovery time, 1.3 V forward voltage @ 3 A) and through-hole axial mounting. The difference is packaging format: /54 is Tape & Reel and /73 is Cut Tape. Selection depends on assembly equipment compatibility, not electrical performance.

Q: What is the difference between fast recovery (RGP30D) and standard recovery (1N5402) diodes?

A: Recovery time differs: RGP30D has 150 ns reverse recovery time (fast recovery ≤500 ns), while 1N5402 has >500 ns (standard recovery). Fast recovery diodes switch off more quickly, reducing switching losses in high-frequency applications. For low-frequency rectification, standard recovery diodes are acceptable and typically lower cost.

Q: Is MUR420GP-TP a suitable substitute despite having 4 A rating instead of 3 A?

A: Yes. Higher current rating indicates greater capacity and does not prevent use in 3 A applications. MUR420GP-TP also provides superior recovery time (60 ns) and lower forward voltage (1.0 V @ 4 A), making it suitable for applications requiring enhanced performance. All other electrical parameters (200 V reverse voltage, through-hole mounting) are compatible.

Q: Are DO-201AA and DO-201AD packages mechanically compatible?

A: Both are axial through-hole packages with the same lead spacing and mounting footprint. DO-201AD is the modern variant designation. Parts specified as DO-201AD are directly compatible with PCB layouts designed for DO-201AA.

Q: What does ROHS3 compliance mean for these substitute parts?

A: ROHS3 compliance indicates the parts meet Restriction of Hazardous Substances Directive requirements, restricting lead, cadmium, mercury, and other hazardous materials. All active substitute parts listed are ROHS3 compliant, ensuring compatibility with modern manufacturing and environmental standards.

Q: Can I use 1N5402-E3/54 in place of RGP30D-E3/54 in a high-frequency switching application?

A: Electrical compatibility exists (200 V, 3 A, 1.2 V forward voltage). However, recovery time differs: 1N5402 has standard recovery (>500 ns) while RGP30D has fast recovery (150 ns). In high-frequency applications, the slower recovery of 1N5402 may increase switching losses and heat generation. Application-specific testing is necessary to confirm suitability.

Q: What is the inventory status of these substitute parts?

A: RGP30D-E3/73 has the highest inventory (4,766 pcs), followed by 1N5402-E3/73 (8,117 pcs). RGP30D-E3/54 has 1,250 pcs, 1N5402-E3/54 has 1,573 pcs, and MUR420GP-TP has 1,036 pcs. Inventory levels support procurement for production applications.
