HER107S-TP Equivalent & Substitute Parts

Part Overview

The HER107S-TP is a general-purpose rectifier diode rated for 800 V DC reverse voltage and 1 A average rectified current. Manufactured by Micro Commercial Co, this through-hole component features fast recovery characteristics with a reverse recovery time of 75 ns. The part is classified as obsolete, which necessitates identification of active equivalent alternatives for new designs and ongoing production requirements. Substitute parts must maintain electrical performance across voltage, current, and thermal specifications while accommodating packaging and supply chain considerations.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the HER107S-TP is determined by equivalence across the following critical parameters:

• Voltage Rating: DC reverse voltage must equal or exceed 800 V
• Current Rating: Average rectified current must equal or exceed 1 A
• Forward Voltage Drop: Maximum forward voltage at rated current must not exceed 1.7 V @ 1 A
• Recovery Characteristics: Fast recovery classification with reverse recovery time ≤ 500 ns for currents > 200 mA
• Reverse Leakage: Leakage current at rated reverse voltage must not exceed specified limits
• Mounting Configuration: Through-hole axial package orientation
• Temperature Range: Operating junction temperature range must encompass -55°C to 125°C
• Compliance: RoHS3 compliance required

The HER107G-TP qualifies as a direct substitute based on identical electrical specifications and compatible through-hole packaging, despite differences in supplier device package designation and product status.

Parameter Comparison

Engineering Selection Recommendations

The HER107G-TP is the qualified substitute for the obsolete HER107S-TP. Selection is based on the following engineering criteria:

Electrical Equivalence: Both parts share identical voltage, current, and thermal specifications. The HER107G-TP demonstrates superior reverse leakage performance (5 µA versus 5 mA), which represents an improvement in device quality without compromising circuit compatibility.

Product Status: The HER107G-TP maintains active product status with confirmed inventory availability (756 Pcs), ensuring long-term supply continuity. The HER107S-TP is classified as obsolete, making the substitute necessary for production continuity.

Compliance and Certification: Both parts maintain ROHS3 compliance and identical moisture sensitivity levels (MSL 1 - Unlimited), ensuring regulatory and environmental compatibility.

Packaging Compatibility: Both components feature through-hole axial mounting. The HER107G-TP is supplied in Tape & Reel (TR) packaging with DO-41 supplier device package designation, which is compatible with standard through-hole assembly processes.

Supply Chain: The HER107G-TP offers superior inventory availability and active manufacturing status, reducing procurement risk and lead time uncertainty.

Frequently Asked Questions (FAQ)

Q: Can the HER107G-TP directly replace the HER107S-TP in existing circuit designs?

A: Yes. The HER107G-TP meets or exceeds all electrical specifications of the HER107S-TP, including voltage rating, current capacity, forward voltage drop, and reverse recovery time. Both components are through-hole axial devices with identical thermal operating ranges.

Q: What is the difference between the A-405 and DO-41 package designations?

A: Both designations refer to axial through-hole packages suitable for the same assembly processes. The A-405 is the supplier device package for HER107S-TP, while DO-41 is the standard industry designation for HER107G-TP. The physical form factor and mounting compatibility remain equivalent.

Q: Why does the HER107G-TP show lower reverse leakage current (5 µA) compared to the HER107S-TP (5 mA)?

A: The difference reflects manufacturing improvements in the active HER107G-TP variant. Lower reverse leakage indicates superior device quality and represents a performance enhancement. This does not affect circuit compatibility and is beneficial for applications sensitive to leakage current.

Q: Is the Tape & Reel packaging of HER107G-TP compatible with manual assembly?

A: Tape & Reel packaging is standard for automated assembly processes. For manual assembly applications, components can be removed from the tape. The through-hole axial form factor remains identical to the original HER107S-TP, ensuring mechanical compatibility with existing assembly fixtures and PCB layouts.

Q: Are there any compliance or certification differences between the two parts?

A: Both parts maintain ROHS3 compliance and identical moisture sensitivity levels. The HER107G-TP includes additional REACH Unaffected status documentation. No compliance barriers exist for substitution.

Q: What inventory considerations should be evaluated for this substitution?

A: The HER107S-TP is obsolete with 678 Pcs in stock. The HER107G-TP is active with 756 Pcs available. For long-term production planning, the HER107G-TP provides superior supply security and eliminates obsolescence risk.
