HER107-TP Equivalent & Substitute Parts

Part Overview

The HER107-TP is a general-purpose rectifier diode rated for 800 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 parts for ongoing design support and procurement continuity. Substitute parts must maintain electrical performance across voltage, current, and thermal specifications while accommodating packaging and availability requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the HER107-TP are identified based on strict electrical and mechanical parameter matching within the rectifier diode category. The substitution logic is based on the following criteria:

Primary Matching Parameters:

• Voltage - DC Reverse (Vr) (Max): 800 V
• Current - Average Rectified (Io): 1 A
• Reverse Recovery Time (trr): 75 ns
• Mounting Type: Through Hole
• Package / Case: DO-204AL, DO-41, Axial

Substitution Categories:

Direct Substitute (Same Manufacturer): HER107G-TP maintains identical electrical specifications and is manufactured by the same supplier (Micro Commercial Co). The primary distinction is product status (Active vs. Obsolete) and packaging format (Tape & Reel vs. bulk).

Similar Substitute (Cross-Manufacturer): UF4006-E3/54 (Vishay General Semiconductor - Diodes Division) meets all critical electrical parameters with minor variations in reverse leakage current and capacitance. Operating temperature range extends to 150°C, providing enhanced thermal margin.

Engineering Selection Recommendations

HER107G-TP Selection Criteria:

HER107G-TP is the primary substitute for HER107-TP applications. This part is manufactured by the same supplier and maintains identical electrical specifications. The part carries Active product status, ensuring long-term availability and supply chain continuity. Both parts are ROHS3 Compliant with unlimited moisture sensitivity level (MSL 1). Selection of HER107G-TP is appropriate for direct replacement in existing designs without circuit modification.

UF4006-E3/54 Selection Criteria:

UF4006-E3/54 serves as a cross-manufacturer alternative when HER107G-TP availability is constrained. This Vishay component meets all critical electrical parameters with equivalent reverse recovery time (75 ns) and forward voltage drop (1.7 V @ 1 A). The extended operating temperature range (-55 to 150°C) provides additional thermal margin in applications approaching the upper temperature limit. Reverse leakage current is specified at 10 µA versus 5 µA for the primary part; this difference remains within acceptable limits for general-purpose rectification applications. Both substitute parts are ROHS3 Compliant and carry Active product status.

Packaging Considerations:

HER107-TP is supplied in bulk format. HER107G-TP is available in Tape & Reel packaging, suitable for automated assembly processes. UF4006-E3/54 is supplied in Cut Tape format. Packaging selection depends on production volume and assembly methodology.

Frequently Asked Questions (FAQ)

Q: Can HER107G-TP be used as a direct replacement for HER107-TP?

A: Yes. HER107G-TP is electrically and mechanically identical to HER107-TP. Both parts share the same base product number (HER107), manufacturer (Micro Commercial Co), and all critical electrical specifications. The primary difference is product status; HER107G-TP is Active while HER107-TP is Obsolete. No circuit modification is required.

Q: What is the difference between HER107G-TP and UF4006-E3/54?

A: Both parts meet the core electrical requirements: 800 V reverse voltage, 1 A average rectified current, 1.7 V forward voltage drop, and 75 ns reverse recovery time. UF4006-E3/54 is manufactured by Vishay and features a higher reverse leakage current specification (10 µA versus 5 µA) and extended operating temperature range (-55 to 150°C versus -55 to 125°C). These differences are acceptable for general-purpose rectification applications.

Q: Are there packaging differences between the substitute parts?

A: Yes. HER107-TP is supplied in bulk format. HER107G-TP is available in Tape & Reel (TR) packaging for automated assembly. UF4006-E3/54 is supplied in Cut Tape (CT) format. All three parts use the same DO-41 package footprint and are mechanically compatible with existing through-hole PCB designs.

Q: Do all substitute parts meet RoHS compliance requirements?

A: Yes. HER107-TP, HER107G-TP, and UF4006-E3/54 are all ROHS3 Compliant. All parts carry Moisture Sensitivity Level 1 (Unlimited), indicating no special moisture handling requirements during storage or assembly.

Q: What is the inventory status of each part?

A: HER107-TP has 903 pieces in stock (Obsolete status). HER107G-TP has 756 pieces in stock (Active status). UF4006-E3/54 has 21,200 pieces in stock (Active status), providing the highest availability for immediate procurement.

Q: Can UF4006-E3/54 be used in applications with temperature requirements above 125°C?

A: UF4006-E3/54 is rated for operating junction temperatures up to 150°C, compared to 125°C for HER107-TP and HER107G-TP. This extended range allows UF4006-E3/54 to be used in higher-temperature environments. However, all three parts maintain identical electrical performance within their respective temperature ranges.

Q: Are there any electrical performance differences that would affect circuit operation?

A: All three parts share identical forward voltage drop (1.7 V @ 1 A) and reverse recovery time (75 ns). UF4006-E3/54 specifies reverse leakage current at 10 µA versus 5 µA for the other parts. This 2x difference in leakage current is negligible in general-purpose rectification applications and does not affect circuit functionality.
