PR1007R-T Equivalent & Substitute Parts

Part Overview

The PR1007R-T is a general-purpose rectifier diode rated for 1000 V DC reverse voltage and 1 A average rectified current in a DO-41 through-hole package. Manufactured by Diodes Incorporated, this component is classified as obsolete. Due to its obsolete product status, sourcing original units from the manufacturer is no longer available through standard distribution channels. Identifying equivalent substitute parts with matching electrical and mechanical specifications is necessary to maintain design continuity and ensure component availability for production and repair applications.

Substitute Part Grouping Explanation

Substitute parts for the PR1007R-T are identified based on strict electrical and mechanical parameter matching. The primary substitution criteria are:

Electrical Parameters (Must Match):

• Voltage - DC Reverse (Vr) (Max): 1000 V
• Current - Average Rectified (Io): 1 A
• Voltage - Forward (Vf) (Max) @ If: 1.3 V @ 1 A
• Speed Classification: Fast Recovery ≤ 500ns, > 200mA (Io)
• Current - Reverse Leakage @ Vr: 5 µA @ 1000 V

Mechanical Parameters (Must Match):

• Mounting Type: Through Hole
• Package / Case: DO-204AL, DO-41, Axial

Compliance Parameters:

• RoHS Status: ROHS3 Compliant

The BA159BULK from EIC Semiconductor Inc. meets all mandatory electrical and mechanical specifications. This part is classified as active product status, ensuring ongoing availability and supply chain continuity.

Parameter Comparison

Engineering Selection Recommendations

The BA159BULK is a direct electrical and mechanical equivalent to the PR1007R-T. Both components satisfy the core rectifier specifications: 1000 V reverse voltage rating, 1 A average rectified current, 1.3 V forward voltage drop, and fast recovery characteristics. Both are packaged in DO-41 through-hole format and maintain ROHS3 compliance.

The primary advantage of selecting BA159BULK is its active product status. The PR1007R-T is obsolete and no longer manufactured by Diodes Incorporated. The BA159BULK is actively produced by EIC Semiconductor Inc., with 18,108 pieces in current inventory, ensuring reliable supply chain access for both new production and field replacement applications.

The BA159BULK demonstrates improved reverse recovery time (250 ns versus 300 ns), which provides enhanced switching performance characteristics. The operating temperature range of the BA159BULK (-65 to 150°C) exceeds the PR1007R-T specification (-55 to 150°C), offering broader thermal operating capability. The capacitance specification of BA159BULK (20 pF @ 4V, 1MHz) is higher than the original part (10 pF @ 4V, 1MHz); this difference is within acceptable tolerance for general-purpose rectifier applications and does not compromise functional compatibility.

Frequently Asked Questions (FAQ)

Q: Can BA159BULK be used as a direct replacement for PR1007R-T in existing designs?

A: Yes. The BA159BULK meets all mandatory electrical specifications (1000 V reverse voltage, 1 A current rating, 1.3 V forward voltage) and mechanical requirements (DO-41 through-hole package). Both components are ROHS3 compliant. The parts are functionally interchangeable for general-purpose rectification applications.

Q: What is the difference in reverse recovery time between these parts?

A: The PR1007R-T has a reverse recovery time of 300 ns, while the BA159BULK is specified at 250 ns. The BA159BULK exhibits faster switching characteristics, which can improve efficiency in high-frequency switching applications. This difference does not prevent substitution; it represents an improvement in performance.

Q: Are there differences in capacitance specifications?

A: Yes. The PR1007R-T is specified at 10 pF @ 4V, 1MHz, while the BA159BULK is specified at 20 pF @ 4V, 1MHz. For general-purpose rectifier applications, this capacitance difference is acceptable and does not affect functional compatibility. Applications requiring specific capacitance characteristics should evaluate this parameter against circuit requirements.

Q: Why is the PR1007R-T listed as obsolete?

A: The PR1007R-T is no longer manufactured by Diodes Incorporated. Obsolete status indicates that the component has been discontinued and is not available through standard manufacturing channels. The BA159BULK is an active product with ongoing production and supply availability.

Q: What is the operating temperature range difference?

A: The PR1007R-T operates from -55°C to 150°C junction temperature. The BA159BULK operates from -65°C to 150°C. The BA159BULK provides a wider low-temperature operating range, making it suitable for applications requiring extended cold-temperature performance. Both parts maintain the same maximum junction temperature of 150°C.

Q: Are both parts RoHS compliant?

A: Yes. Both the PR1007R-T and BA159BULK are ROHS3 compliant, meeting environmental and regulatory requirements for lead-free manufacturing and hazardous substance restrictions.

Q: What packaging format is used for the BA159BULK?

A: The BA159BULK is supplied in bag packaging, consistent with the DO-41 through-hole axial lead format. This packaging is standard for general-purpose rectifier diodes and is compatible with automated and manual assembly processes.
