FR102-AP Equivalent & Substitute Parts

Part Overview

The FR102-AP is a general-purpose rectifier diode manufactured by Micro Commercial Co, rated for 100 V DC reverse voltage and 1 A average rectified current in a DO-41 through-hole package. This component is classified as obsolete, making identification of active equivalent and substitute parts essential for ongoing design support and procurement continuity. Equivalent parts maintain identical electrical and mechanical specifications, while substitute parts provide functional alternatives within the same application category.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the FR102-AP is determined by the following critical parameters:

Mandatory Matching Criteria:

• Voltage - DC Reverse (Vr) (Max): 100 V
• Current - Average Rectified (Io): 1 A
• Mounting Type: Through Hole
• Package / Case: DO-204AL, DO-41, Axial
• Operating Temperature - Junction: -55°C ~ 150°C
• RoHS Status: ROHS3 Compliant

Allowable Variation Parameters:

• Voltage - Forward (Vf) (Max) @ If: ≤ 1.3 V @ 1 A
• Reverse Recovery Time (trr): ≤ 150 ns
• Current - Reverse Leakage @ Vr: ≤ 5 µA @ 100 V
• Capacitance @ Vr, F: Variation permitted within fast recovery classification

All identified substitute parts meet or exceed the mandatory matching criteria and operate within allowable variation ranges for fast recovery rectifier diodes in the 100 V, 1 A classification.

Engineering Selection Recommendations

1N4934GP-AP (Micro Commercial Co)

The 1N4934GP-AP is an active product from the same manufacturer as the obsolete FR102-AP. This part maintains identical voltage and current ratings with a forward voltage specification of 1.2 V @ 1 A, which is superior to the original 1.3 V specification. The reverse recovery time of 200 ns is within acceptable variation for fast recovery rectifier applications. This part is recommended as the primary replacement for direct substitution in new procurement and design updates.

FR102A-G (Comchip Technology)

The FR102A-G is an active product offering identical electrical specifications to the FR102-AP, including forward voltage of 1.3 V @ 1 A and reverse recovery time of 150 ns. The packaging is specified as Tape & Box (TB), which differs from the original packaging designation. Capacitance is specified at 25 pF @ 4V, 1MHz, representing a variation within acceptable limits for this component class. This part is suitable for applications where Comchip Technology sourcing is preferred or required.

FR102G A0G (Taiwan Semiconductor Corporation)

The FR102G A0G is an active product from Taiwan Semiconductor Corporation, maintaining all critical electrical parameters of the FR102-AP. The reverse recovery time of 150 ns matches the original specification exactly. Capacitance is specified at 10 pF @ 4V, 1MHz, representing the lowest value among substitute options. This part is suitable for applications where Taiwan Semiconductor Corporation sourcing is preferred or required.

All three substitute parts are ROHS3 compliant and maintain the operating temperature range of -55°C ~ 150°C. Selection among these options is based on manufacturer preference, packaging requirements, and procurement availability.

Frequently Asked Questions (FAQ)

Q: Can the 1N4934GP-AP replace the FR102-AP in all applications?

A: The 1N4934GP-AP meets all mandatory electrical and mechanical specifications for the FR102-AP. The forward voltage of 1.2 V @ 1 A is lower than the original 1.3 V specification, which is acceptable for general-purpose rectifier applications. The reverse recovery time of 200 ns is within the fast recovery classification. Direct substitution is supported.

Q: What is the difference between the FR102A-G and FR102G A0G?

A: Both parts maintain identical voltage and current ratings. The primary differences are manufacturer (Comchip Technology versus Taiwan Semiconductor Corporation) and capacitance specification (25 pF versus 10 pF @ 4V, 1MHz). Both are active products with ROHS3 compliance. Selection depends on manufacturer preference and procurement availability.

Q: Does packaging affect substitution compatibility?

A: All substitute parts are specified for DO-204AL, DO-41, Axial through-hole mounting. The FR102A-G is packaged in Tape & Box (TB) format, while the original FR102-AP packaging designation is not specified. Both formats are compatible with through-hole assembly processes. Verify tape specifications with your assembly partner if automated handling is required.

Q: Are all substitute parts ROHS3 compliant?

A: All three substitute parts are ROHS3 compliant, matching the compliance status of the FR102-AP. The 1N4934GP-AP and FR102G A0G include REACH Unaffected status in their specifications.

Q: What is the significance of reverse recovery time variation?

A: The FR102-AP specifies 150 ns reverse recovery time. The 1N4934GP-AP specifies 200 ns, which remains within the fast recovery classification (≤ 500ns, > 200mA). This variation is acceptable for general-purpose rectifier applications. The FR102A-G and FR102G A0G maintain the 150 ns specification.

Q: Can these parts be used interchangeably in existing designs?

A: All substitute parts maintain the 100 V reverse voltage rating, 1 A average rectified current, and through-hole DO-41 package configuration. Electrical performance differences are within acceptable ranges for fast recovery rectifier applications. Substitution is supported without design modification.
