FR107-T Equivalent & Substitute Parts

Part Overview

The FR107-T is a general-purpose rectifier diode manufactured by Diodes Incorporated, rated for 1000 V DC reverse voltage and 1 A average rectified current in a through-hole DO-41 package. This part is classified as obsolete, which necessitates identification of active equivalent and substitute components for ongoing design support and procurement continuity. Active alternatives with matching or superior electrical characteristics are available from multiple manufacturers.

Current - Average Rectified (Io): 1 A
Mounting Type: Through Hole
Package / Case: DO-204AL, DO-41, Axial

Secondary Compatibility Factors:

Reverse Recovery Time (trr): Fast Recovery ≤ 500 ns or Standard Recovery > 500 ns
Voltage - Forward (Vf) (Max) @ If: 1.0 V to 1.3 V @ 1 A
Current - Reverse Leakage @ Vr: ≤ 5 µA @ 1000 V

Engineering Selection Recommendations

Direct Replacement (Fast Recovery Technology):

PR1007G-T, BA159GP-E3/54, RGP10M-E3/54, and RGP10ME-E3/54 are direct electrical equivalents to the FR107-T. All four parts maintain identical reverse voltage (1000 V), average rectified current (1 A), forward voltage (1.3 V @ 1 A), and reverse recovery time (500 ns) specifications. These parts are manufactured by Diodes Incorporated and Vishay General Semiconductor, both with active product status and ROHS3 compliance. PR1007G-T is the closest match from the same manufacturer as the original part. BA159GP-E3/54, RGP10M-E3/54, and RGP10ME-E3/54 are Vishay alternatives with identical electrical performance and extended temperature range matching the FR107-T (-65°C ~ 175°C).

Functional Replacement (Standard Recovery Technology):

1N3957GP-E3/54, 1N3957GP-E3/73, 1N4007-AP, 1N4007-BP, 1N4007-E3/73, and 1N4007-TP are functional substitutes with standard recovery characteristics (trr > 500 ns). These parts meet the primary voltage and current requirements (1000 V, 1 A) and are suitable for applications where fast recovery is not critical. The 1N4007 series represents the most widely available standard recovery alternative, with 1N4007-TP offering the largest inventory (430,771 pcs). All substitute parts carry ROHS3 compliance and REACH Unaffected status.

Packaging Considerations:

The FR107-T is specified in DO-41 package. Substitute parts are available in DO-41 (PR1007G-T, 1N4007-AP, 1N4007-BP, 1N4007-TP) and DO-204AL (BA159GP-E3/54, RGP10M-E3/54, RGP10ME-E3/54, 1N3957GP-E3/54, 1N3957GP-E3/73, 1N4007-E3/73). DO-204AL and DO-41 are mechanically equivalent axial packages and are interchangeable in through-hole applications.

Compliance Status:

All substitute parts are ROHS3 compliant. BA159GP-E3/54, RGP10M-E3/54, RGP10ME-E3/54, 1N3957GP-E3/54, 1N3957GP-E3/73, 1N4007-AP, 1N4007-BP, 1N4007-E3/73, and 1N4007-TP are REACH Unaffected, providing regulatory advantage over the original FR107-T (REACH Affected).

Frequently Asked Questions (FAQ)

Q: Can PR1007G-T directly replace FR107-T in all applications?

A: PR1007G-T is electrically identical to FR107-T with matching voltage (1000 V), current (1 A), forward voltage (1.3 V @ 1 A), and recovery time (500 ns) specifications. Both are through-hole DO-41 packages. The primary difference is product status: PR1007G-T is active while FR107-T is obsolete. PR1007G-T has a slightly lower maximum junction temperature (150°C vs. 175°C), which must be evaluated for applications operating near the upper temperature limit.

Q: What is the difference between fast recovery and standard recovery diodes?

A: Fast recovery diodes (FR107-T, PR1007G-T, BA159GP-E3/54, RGP10M-E3/54, RGP10ME-E3/54) have reverse recovery times ≤ 500 ns, reducing switching losses in high-frequency applications. Standard recovery diodes (1N3957 series, 1N4007 series) have reverse recovery times > 500 ns (typically 2 µs), making them suitable for lower-frequency rectification where switching speed is less critical. Both technologies satisfy the 1000 V / 1 A rating.

Q: Are DO-41 and DO-204AL packages interchangeable?

A: DO-41 and DO-204AL are mechanically equivalent axial through-hole packages with identical lead spacing and footprint. Components in either package can be used interchangeably in PCB designs with standard through-hole axial component footprints.

Q: Which substitute offers the best inventory availability?

A: 1N4007-TP from Micro Commercial Co has the highest inventory level at 430,771 pcs. For fast recovery alternatives, PR1007G-T offers 19,872 pcs and BA159GP-E3/54 offers 5,700 pcs.

Q: Does the forward voltage difference between FR107-T (1.3 V) and 1N4007 series (1.0-1.1 V) affect circuit performance?

A: Forward voltage differences of 0.2-0.3 V are within typical design tolerances for rectifier applications. The lower forward voltage of 1N4007 series results in reduced power dissipation. Circuit performance impact depends on application-specific requirements; designs with tight voltage regulation or high-current paths should evaluate the specific forward voltage characteristics.

Q: Are all substitute parts ROHS3 compliant?

A: All substitute parts listed are ROHS3 compliant. Additionally, BA159GP-E3/54, RGP10M-E3/54, RGP10ME-E3/54, 1N3957GP-E3/54, 1N3957GP-E3/73, 1N4007-AP, 1N4007-BP, 1N4007-E3/73, and 1N4007-TP are REACH Unaffected, providing regulatory advantage over the original FR107-T which is REACH Affected.

Q: What is the operating temperature range consideration for substitution?

A: FR107-T operates from -65°C to 175°C. PR1007G-T operates to 150°C maximum, which is 25°C lower. Fast recovery alternatives (BA159GP-E3/54, RGP10M-E3/54, RGP10ME-E3/54) match the full -65°C to 175°C range. Standard recovery alternatives operate to 150°C maximum. Applications requiring operation above 150°C must use BA159GP-E3/54, RGP10M-E3/54, or RGP10ME-E3/54.
