FR107-TP Equivalent & Substitute Parts

Part Overview

The FR107-TP is a general-purpose rectifier diode manufactured by Micro Commercial Co, rated for 1000 V DC reverse voltage and 1 A average rectified current in a DO-41 through-hole package. This component is classified as obsolete, though 1061 pieces remain in stock as new original inventory. Due to its obsolete status, equivalent and substitute parts from active manufacturers are necessary for ongoing design support and procurement continuity.

Substitute Part Grouping Explanation

Substitution of the FR107-TP is determined by electrical and mechanical parameter equivalence within the rectifier diode category. The critical parameters governing substitutability are:

Electrical Parameters:

Voltage - DC Reverse (Vr) (Max): 1000 V
Current - Average Rectified (Io): 1 A
Voltage - Forward (Vf) (Max) @ If: 1.3 V @ 1 A
Reverse Recovery Time (trr): 500 ns
Speed: Fast Recovery ≤ 500ns, > 200mA (Io)

Mechanical Parameters:

Mounting Type: Through Hole
Package / Case: DO-204AL, DO-41, Axial

Compliance Parameters:

RoHS Status: ROHS3 Compliant
Moisture Sensitivity Level (MSL): 1 (Unlimited)

Substitute parts are classified into two categories: Direct Manufacturer Equivalents (same base product number, different packaging) and Parametric Equivalents (different manufacturers or base product numbers with identical electrical specifications). All listed substitutes maintain the core electrical ratings and through-hole mounting configuration required for FR107-TP replacement.

Engineering Selection Recommendations

Primary Recommendation: FR107GP-TP

FR107GP-TP is the direct manufacturer equivalent from Micro Commercial Co with active product status. It maintains identical electrical specifications to the FR107-TP while offering current availability (742 pieces in stock). This part is the preferred choice for direct replacement in existing designs.

Secondary Recommendation: 1N4948GP-TP

1N4948GP-TP is a parametric equivalent from Micro Commercial Co with active status and 752 pieces available. It provides identical electrical performance and is suitable for applications where the 1N4948 base product number is acceptable.

Alternative Recommendations: FR107T-G and PG1010R_AY_00001

FR107T-G (Comchip Technology) and PG1010R_AY_00001 (Panjit International Inc.) are parametric equivalents with active product status and substantial inventory availability (868 and 5825 pieces respectively). Both maintain the required electrical specifications and through-hole DO-41 packaging.

Vishay Alternatives: 1N4948GP-E3/73 and BA159-E3/73

Vishay General Semiconductor parts offer extended operating temperature ranges and lower reverse leakage current specifications. 1N4948GP-E3/73 supports -65°C to 175°C operation with 1 µA reverse leakage. BA159-E3/73 provides -65°C to 125°C operation with 5 µA reverse leakage. Both are ROHS3 compliant and available in high quantities (780 and 10359 pieces respectively).

All recommended substitutes are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating, matching the compliance profile of the original FR107-TP.

Frequently Asked Questions (FAQ)

Q: Can FR107GP-TP directly replace FR107-TP in all applications?

A: Yes. FR107GP-TP is a direct manufacturer equivalent with identical electrical specifications (1000 V, 1 A, 1.3 V forward voltage, 500 ns recovery time) and through-hole DO-41 packaging. The only difference is packaging format (Tape & Reel versus bulk), which does not affect electrical performance.

Q: What is the difference between parametric equivalents like 1N4948GP-TP and direct equivalents like FR107GP-TP?

A: Direct equivalents share the same base product number (FR107) and manufacturer. Parametric equivalents use different base product numbers (1N4948, BA159, PG1010) but meet identical electrical specifications. Both categories are suitable for replacement; selection depends on design documentation requirements and supplier availability.

Q: Are Vishay parts (1N4948GP-E3/73, BA159-E3/73) compatible with FR107-TP?

A: Yes, with considerations. Both Vishay parts meet the core electrical specifications (1000 V, 1 A, 1.3 V forward voltage, 500 ns recovery time). 1N4948GP-E3/73 offers extended temperature range (-65°C to 175°C versus -55°C to 150°C) and lower reverse leakage (1 µA versus 5 µA). BA159-E3/73 maintains 5 µA reverse leakage but operates to -65°C. These differences are beneficial for demanding thermal environments.

Q: Does packaging format (DO-41 versus DO-204AL) affect substitutability?

A: No. DO-41 and DO-204AL are equivalent package designations for the same axial through-hole form factor. All listed substitutes use this same physical package and are mechanically interchangeable on PCBs designed for FR107-TP.

Q: Which substitute offers the best inventory availability?

A: BA159-E3/73 from Vishay offers the highest inventory (10359 pieces), followed by PG1010R_AY_00001 from Panjit (5825 pieces) and FR107G from Taiwan Semiconductor (2400 pieces). FR107GP-TP provides 742 pieces from the original manufacturer.

Q: Are all substitutes ROHS3 compliant?

A: Yes. All listed substitutes maintain ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity rating, matching the environmental and regulatory profile of the FR107-TP.

Q: Can I use these substitutes in high-temperature applications?

A: The FR107-TP operates to 150°C junction temperature. Vishay 1N4948GP-E3/73 extends this to 175°C, providing additional thermal margin. For applications approaching or exceeding 150°C, the Vishay part is the preferred choice.
