FR105GP-TP Equivalent & Substitute Parts

Part Overview

The FR105GP-TP is a general-purpose rectifier diode manufactured by Micro Commercial Co, rated for 600 V DC reverse voltage and 1 A average rectified current in a through-hole DO-41 package. This component is classified as Active product status and is RoHS3 compliant. Substitute parts become necessary when the primary part experiences supply constraints, extended lead times, or when alternative packaging formats are required for specific manufacturing processes while maintaining electrical and mechanical compatibility.

Substitute Part Grouping Explanation

Substitution of the FR105GP-TP is determined by strict equivalence across the following critical parameters: maximum reverse voltage (600 V), average rectified current (1 A), forward voltage drop (1.3 V @ 1 A), reverse recovery time (250 ns), reverse leakage current (5 µA @ 600 V), through-hole mounting configuration, and DO-41 package compatibility. All substitute parts listed maintain these electrical specifications and mechanical form factors. Packaging format variations (Tape & Reel versus Cut Tape) do not affect functional equivalence but reflect different supply chain configurations. Product status differences are noted where applicable to support design decision-making.

Engineering Selection Recommendations

FR105G and FR105G A0G (Taiwan Semiconductor Corporation) are parametric equivalents with Active product status, making them the primary substitutes for new designs and ongoing production. Both parts maintain identical electrical specifications to the FR105GP-TP and are available in Cut Tape packaging format. The FR105G offers 10,952 pieces in stock inventory, while FR105G A0G provides 5,309 pieces. Both are ROHS3 compliant and REACH unaffected.

RGP10J (onsemi) is electrically equivalent across all critical parameters but carries a Not For New Designs product status. This part is suitable for legacy system maintenance and repair applications where existing designs require component replacement. RGP10J offers the highest inventory availability at 16,900 pieces and operates across an extended temperature range (-65°C ~ 175°C). This part is ROHS3 compliant and REACH unaffected.

All substitute parts share identical voltage ratings, current ratings, forward voltage characteristics, and recovery time specifications. Selection between Active-status alternatives should be based on packaging preference (Tape & Reel versus Cut Tape), inventory availability, and lead time requirements. The RGP10J substitute is restricted to maintenance and repair contexts due to its Not For New Designs classification.

Frequently Asked Questions (FAQ)

Q: Can FR105G or FR105G A0G be used as direct replacements for FR105GP-TP in new designs?

A: Yes. Both FR105G and FR105G A0G maintain identical electrical specifications (600 V reverse voltage, 1 A current rating, 1.3 V forward voltage, 250 ns recovery time) and through-hole DO-41 package compatibility. Both carry Active product status, making them suitable for new design implementations.

Q: What is the difference between Tape & Reel and Cut Tape packaging?

A: Tape & Reel (TR) packaging supplies components on continuous carrier tape wound on reels, suitable for automated assembly processes. Cut Tape (CT) packaging provides components on cut segments of carrier tape, suitable for manual assembly or lower-volume production. Both formats contain identical components with no electrical or mechanical differences.

Q: Why is RGP10J marked as Not For New Designs?

A: The Not For New Designs status indicates that onsemi has designated this part for legacy support only. While RGP10J is electrically and mechanically equivalent to FR105GP-TP, it should be used only for maintenance, repair, and rework of existing systems. New product designs should utilize FR105G or FR105G A0G.

Q: Are there temperature range differences between substitute parts?

A: Yes. RGP10J operates across -65°C ~ 175°C, providing a wider temperature range than FR105GP-TP, FR105G, and FR105G A0G, which all operate across -55°C ~ 150°C. For applications within the -55°C ~ 150°C range, all parts are functionally equivalent. Applications requiring extended low-temperature operation below -55°C or high-temperature operation above 150°C must use RGP10J.

Q: Do all substitute parts meet the same compliance standards?

A: Yes. FR105GP-TP, RGP10J, FR105G, and FR105G A0G are all ROHS3 compliant and REACH unaffected. All parts carry EAR99 ECCN classification and 8541.10.0080 HTSUS code.

Q: What inventory levels are available for each substitute?

A: FR105GP-TP (Micro Commercial Co) has 1,098 pieces in stock. RGP10J (onsemi) has 16,900 pieces. FR105G (Taiwan Semiconductor) has 10,952 pieces. FR105G A0G (Taiwan Semiconductor) has 5,309 pieces.

Q: Can capacitance differences affect circuit performance?

A: FR105GP-TP and RGP10J specify 15 pF @ 4V, 1MHz, while FR105G and FR105G A0G specify 10 pF @ 4V, 1MHz. For most general-purpose rectification applications, this 5 pF difference is not functionally significant. Applications with specific capacitance requirements should confirm compatibility with circuit design parameters.
