FR102-TP Equivalent & Substitute Parts

Part Overview

The FR102-TP 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 through-hole DO-41 package. This component is classified as obsolete, necessitating identification of active equivalent alternatives for ongoing design support and procurement continuity. Substitute parts must maintain electrical performance across voltage, current, and thermal specifications while accommodating packaging and manufacturing variations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the FR102-TP is determined by strict equivalence across the following electrical and mechanical parameters:

Critical Matching Parameters:

• Voltage - DC Reverse (Vr) (Max): 100 V
• Current - Average Rectified (Io): 1 A
• Voltage - Forward (Vf) (Max) @ If: 1.3 V @ 1 A
• Speed Classification: Fast Recovery ≤ 500ns, > 200mA (Io)
• Reverse Recovery Time (trr): 150 ns
• Mounting Type: Through Hole
• Package / Case: DO-204AL, DO-41, Axial
• Operating Temperature - Junction: -55°C to 150°C
• RoHS Status: ROHS3 Compliant

All identified substitute parts maintain these core electrical specifications. Variations in reverse leakage current and junction capacitance remain within acceptable engineering tolerances for general-purpose rectification applications. Packaging format (bulk versus tape & reel) and supplier device package designations (DO-41 versus DO-204AL) do not affect electrical interchangeability.

Parameter Comparison

Engineering Selection Recommendations

All four substitute parts—FR102G, FR102G R1G, FR102T-G, and PG101R_R2_00001—are electrically equivalent to the FR102-TP and maintain active product status with manufacturers. Selection among these alternatives is based on the following criteria:

Compliance and Certification: All substitute parts carry ROHS3 compliance certification, matching the original FR102-TP specification. FR102G and FR102G R1G additionally carry REACH Unaffected status, providing enhanced regulatory documentation for applications requiring extended supply chain traceability.

Availability and Inventory: FR102G R1G (Taiwan Semiconductor Corporation) offers the highest current inventory at 1,117 pieces. FR102G provides 1,084 pieces, FR102T-G (Comchip Technology) provides 1,029 pieces, and PG101R_R2_00001 (Panjit International Inc.) provides 858 pieces. Inventory levels support both prototype and production-volume procurement.

Packaging Format: FR102T-G and PG101R_R2_00001 are supplied in tape & reel format, suitable for automated assembly processes. FR102G and FR102G R1G are supplied in bulk packaging. Selection depends on manufacturing process requirements.

Reverse Leakage Characteristics: PG101R_R2_00001 exhibits lower reverse leakage current (1 µA @ 100 V) compared to the original specification (5 µA @ 100 V), providing improved performance in low-leakage applications without compromising compatibility.

Frequently Asked Questions (FAQ)

Q: Can FR102G, FR102G R1G, FR102T-G, and PG101R_R2_00001 be used interchangeably with FR102-TP?

A: Yes. All four substitute parts maintain identical electrical specifications across voltage rating, current capacity, forward voltage drop, recovery time, and operating temperature range. Through-hole mounting and axial package geometry ensure mechanical compatibility with existing PCB layouts.

Q: What is the difference between FR102G and FR102G R1G?

A: Both parts are manufactured by Taiwan Semiconductor Corporation and maintain identical electrical specifications. FR102G R1G includes an additional revision designation (R1G) in the part number. Both carry ROHS3 compliance and REACH Unaffected status. Selection between these variants depends on supplier availability and internal part number tracking requirements.

Q: Does packaging format (bulk versus tape & reel) affect electrical performance?

A: No. Packaging format affects only manufacturing process compatibility and handling procedures. Electrical specifications remain identical regardless of whether the component is supplied in bulk or tape & reel format. FR102T-G and PG101R_R2_00001 in tape & reel format are suitable for automated pick-and-place assembly, while FR102G and FR102G R1G in bulk format are suitable for manual or semi-automated assembly processes.

Q: Why does PG101R_R2_00001 show lower reverse leakage current (1 µA) compared to the original FR102-TP (5 µA)?

A: Lower reverse leakage current represents improved device performance and does not compromise compatibility. Applications designed for the original 5 µA specification operate within acceptable parameters with the lower leakage characteristic. This variation falls within normal manufacturing tolerances for general-purpose rectifier diodes.

Q: Are all substitute parts RoHS compliant?

A: Yes. All four substitute parts carry ROHS3 compliance certification, matching the original FR102-TP specification. FR102G and FR102G R1G additionally carry REACH Unaffected status for enhanced regulatory documentation.

Q: What is the significance of the DO-204AL and DO-41 package designations?

A: DO-204AL and DO-41 are equivalent package designations for the same axial through-hole diode package. Both designations refer to identical physical dimensions and pin configurations. Supplier device package specifications may use either designation interchangeably.
