DR754-TP Equivalent & Substitute Parts

Part Overview

The DR754-TP is a general-purpose rectifier diode manufactured by Micro Commercial Co, rated for 400V DC reverse voltage and 6A average rectified current in an R-6 axial through-hole package. This component is classified as "Not For New Designs," indicating it has reached end-of-life status. Identification of equivalent substitute parts is necessary for ongoing maintenance, repair, and legacy system support where the original part is no longer readily available or where design flexibility permits component substitution.

Substitute Part Grouping Explanation

Substitution of the DR754-TP is determined by electrical and mechanical compatibility across the following critical parameters:

Electrical Compatibility Criteria:

• Voltage - DC Reverse (Vr) (Max): 400 V minimum
• Current - Average Rectified (Io): 6 A minimum
• Voltage - Forward (Vf) (Max) @ If: 1.1 V @ 6 A maximum
• Speed: Standard Recovery >500ns, > 200mA (Io)
• Current - Reverse Leakage @ Vr: 10 µA @ 400 V maximum
• Capacitance @ Vr, F: 100 pF @ 4V, 1MHz maximum

Mechanical Compatibility Criteria:

• Mounting Type: Through Hole
• Package / Case: Axial configuration
• Operating Temperature - Junction: -50°C to 150°C minimum range

The substitute part 6A04-G meets all electrical specifications and operates within compatible temperature and mechanical parameters, with the exception of package designation (P600 versus R-6) and packaging format (Cut Tape versus Tape & Reel). Both packages are axial through-hole configurations suitable for identical circuit board layouts.

Parameter Comparison

Engineering Selection Recommendations

The 6A04-G manufactured by Comchip Technology is a direct electrical and mechanical substitute for the DR754-TP. Selection of this substitute part is supported by the following factors:

Compliance and Regulatory Status: Both parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment for applications requiring environmental compliance certification.

Product Lifecycle Considerations: The DR754-TP carries "Not For New Designs" status, indicating obsolescence. The 6A04-G maintains "Active" product status, ensuring long-term availability and supply chain continuity for ongoing production and maintenance applications.

Electrical Performance: The 6A04-G demonstrates equivalent or superior electrical characteristics across all critical parameters. Reverse leakage current is lower (5 µA versus 10 µA), representing improved performance without introducing incompatibility.

Mechanical and Thermal Compatibility: Both components utilize through-hole axial mounting with compatible physical form factors. Operating temperature ranges overlap sufficiently for standard industrial applications, with the 6A04-G supporting -55°C minimum operation compared to -50°C for the DR754-TP.

Packaging and Inventory: The 6A04-G is available in significantly higher inventory (25,184 pieces) compared to the DR754-TP (922 pieces), supporting both immediate procurement and long-term supply requirements.

Frequently Asked Questions (FAQ)

Q: Can the 6A04-G be used as a direct replacement for the DR754-TP in existing circuits?

A: Yes. The 6A04-G meets or exceeds all electrical specifications of the DR754-TP, including voltage rating, current capacity, forward voltage drop, and reverse leakage characteristics. Both components are through-hole axial diodes with identical mounting requirements.

Q: What is the difference between the R-6 and P600 package designations?

A: R-6 and P600 are manufacturer-specific package designations for axial through-hole diodes. Both represent the same physical form factor and are mechanically interchangeable in circuit board layouts. The designation difference reflects different manufacturer standards rather than physical incompatibility.

Q: Does the lower reverse leakage current of the 6A04-G affect circuit operation?

A: No. Lower reverse leakage current (5 µA versus 10 µA) represents improved performance and does not introduce circuit incompatibility. This characteristic is beneficial in applications sensitive to leakage current.

Q: Are there temperature range differences that affect substitution?

A: The operating temperature ranges differ slightly: DR754-TP operates from -50°C to 150°C, while 6A04-G operates from -55°C to 125°C. For applications within the overlapping range (-50°C to 125°C), both parts are fully compatible. Applications requiring operation above 125°C require the original DR754-TP specification.

Q: What is the significance of the "Not For New Designs" status on the DR754-TP?

A: This designation indicates the part has reached end-of-life status and is no longer recommended for new product development. Existing inventory remains available for maintenance and repair of legacy systems. The 6A04-G, with "Active" status, is the appropriate choice for new designs and ongoing production.

Q: Does the packaging format difference (Tape & Reel versus Cut Tape) affect electrical performance?

A: No. Packaging format affects only handling, storage, and automated assembly processes. Electrical and mechanical performance of the component itself is independent of packaging format. Both formats deliver identical diode specifications.
