Substitute Part Grouping Explanation

Substitution of the RGF1D is determined by strict electrical and mechanical parameter matching. The critical parameters that define substitutability are:

Electrical Parameters:

Voltage - DC Reverse (Vr) (Max): 200 V
Current - Average Rectified (Io): 1 A
Voltage - Forward (Vf) (Max) @ If: 1.3 V @ 1 A (or lower)
Speed: Fast Recovery ≤ 500ns, > 200mA (Io)
Reverse Recovery Time (trr): 150 ns (or lower)
Current - Reverse Leakage @ Vr: 5 µA @ 200 V (or lower)

Mechanical Parameters:

Mounting Type: Surface Mount
Package / Case: DO-214AC (SMA) or DO-214BA (GF1)

Substitute parts are grouped into two categories:

Category 1: Direct Package Equivalents (DO-214AC / SMA) Parts with identical package designation and all electrical parameters meeting or exceeding RGF1D specifications. These include RS1D, CFRA103-G, CGRA4003-G, CMR1-02M BK PBFREE, and CMR1F-02M BK PBFREE.

Category 2: Alternative Package Equivalents (DO-214BA / GF1) Parts with alternative but compatible surface mount packages (DO-214BA) that meet all electrical specifications. These include RGF1D-E3/67A and EGF1D-E3/5CA. Package compatibility must be verified for specific PCB layouts.

Category 3: Obsolete or Limited Availability FS1DE-TP is classified as obsolete and is included for reference only; substitution is not recommended for new designs.

Engineering Selection Recommendations

For Active Production and New Designs:

The RGF1D is designated "Not For New Designs." Selection of an active substitute is required for new design implementations.

Recommended Primary Substitutes (DO-214AC / SMA Package):

RS1D (Taiwan Semiconductor Corporation) is the preferred direct substitute. It maintains identical electrical specifications (200 V, 1 A, 1.3 V forward voltage, 150 ns reverse recovery time) and is in active product status with 20,200 units in stock. Operating temperature range is -55°C to 150°C, which is narrower than the RGF1D but suitable for most commercial and industrial applications.

CMR1F-02M BK PBFREE and CMR1F-02M TR13 PBFREE (Central Semiconductor Corp) are alternative direct substitutes with identical electrical specifications and active status. Both are available in bulk and tape & reel packaging with 1,083 and 779 units in stock respectively. Operating temperature range is -65°C to 150°C.

CFRA103-G (Comchip Technology) and CGRA4003-G (Comchip Technology) are additional active alternatives in DO-214AC package. CGRA4003-G offers lower forward voltage (1.1 V @ 1 A) compared to the RGF1D specification of 1.3 V @ 1 A.

Recommended Alternative Substitutes (DO-214BA / GF1 Package):

RGF1D-E3/67A (Vishay General Semiconductor - Diodes Division) is an active substitute with identical electrical specifications and operating temperature range (-65°C to 175°C) matching the RGF1D. The DO-214BA (GF1) package is mechanically compatible with surface mount assembly but requires PCB layout verification for pin compatibility.

EGF1D-E3/5CA (Vishay General Semiconductor - Diodes Division) is an active substitute with superior performance characteristics: forward voltage of 1.0 V @ 1 A (lower than RGF1D) and reverse recovery time of 50 ns (faster than RGF1D's 150 ns). Operating temperature range is -65°C to 175°C. The DO-214BA (GF1) package requires PCB layout verification.

Compliance and Certification:

All recommended substitutes are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99. Moisture Sensitivity Level (MSL) is 1 (Unlimited) for all parts, indicating no special moisture handling requirements.

Not Recommended:

FS1DE-TP (Micro Commercial Co) is classified as obsolete and is not recommended for new designs or ongoing production.

Frequently Asked Questions (FAQ)

Q: Can RS1D be used as a direct replacement for RGF1D in existing designs?

A: RS1D is electrically equivalent to RGF1D with identical voltage (200 V), current (1 A), forward voltage (1.3 V @ 1 A), and recovery characteristics (150 ns). Both use the DO-214AC (SMA) package. The operating temperature range of RS1D (-55°C to 150°C) is narrower than RGF1D (-65°C to 175°C). Substitution is valid for applications within the RS1D temperature range.

Q: What is the difference between DO-214AC (SMA) and DO-214BA (GF1) packages?

A: Both are surface mount packages for rectifier diodes. DO-214AC (SMA) and DO-214BA (GF1) have different physical dimensions and pin configurations. PCB layouts designed for one package cannot directly accommodate the other without modification. Verify footprint compatibility before substituting between these package types.

Q: Why do some substitute parts have lower forward voltage specifications?

A: Forward voltage (Vf) is a characteristic of the semiconductor material and design. CGRA4003-G specifies 1.1 V @ 1 A and EGF1D-E3/5CA specifies 1.0 V @ 1 A, both lower than RGF1D's 1.3 V @ 1 A. Lower forward voltage reduces power dissipation and heat generation. Parts with lower Vf are direct substitutes as long as the application does not depend on the higher forward voltage value.

Q: What does "Fast Recovery ≤ 500ns, > 200mA (Io)" mean?

A: This specification indicates the diode is a fast recovery rectifier with reverse recovery time of 500 nanoseconds or less at currents greater than 200 milliamps. Fast recovery diodes are suitable for high-frequency switching applications. Standard recovery diodes (>500ns) are slower and generate more switching losses.

Q: Are CMR1-02M and CMR1F-02M interchangeable?

A: No. CMR1-02M is a standard recovery diode (>500ns) with 1.1 V forward voltage. CMR1F-02M is a fast recovery diode (≤ 500ns, 150 ns trr) with 1.3 V forward voltage. These are different product lines with different electrical characteristics. Selection depends on application switching frequency requirements.

Q: What is the significance of "Not For New Designs" status?

A: This designation indicates the RGF1D has reached end-of-life and is no longer recommended for new product development. Existing inventory remains available for legacy product support. New designs must select from active product alternatives to ensure long-term supply availability and manufacturer support.

Q: Can I use EGF1D-E3/5CA instead of RGF1D for improved performance?

A: EGF1D-E3/5CA has superior electrical characteristics: lower forward voltage (1.0 V vs. 1.3 V) and faster reverse recovery (50 ns vs. 150 ns). These improvements reduce power dissipation and enable higher switching frequencies. The DO-214BA (GF1) package requires PCB layout verification. Electrical substitution is valid; mechanical compatibility must be confirmed.

Q: What packaging options are available for substitute parts?

A: Substitute parts are available in multiple packaging formats: Cut Tape (CT), Tape & Reel (TR), and Bulk. RS1D is available in Tape & Reel. CMR1-02M BK PBFREE is available in Bulk; CMR1-02M TR13 PBFREE is available in Tape & Reel. Select packaging based on production volume and assembly requirements.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All substitute parts listed are ROHS3 compliant and REACH unaffected, meeting environmental and regulatory requirements for commercial and industrial applications.
