Substitute Part Grouping Explanation

Substitute diodes for the CR2-160 TR are selected based on the following critical parameters:

Voltage Rating: All substitutes must maintain a minimum DC reverse voltage (Vr) of 1600 V to ensure equivalent blocking capability.

Current Rating: Substitute parts must support the application's current requirements. The CR2-160 TR is rated for 2 A average rectified current. Substitutes may exceed this rating without functional degradation.

Forward Voltage Characteristics: Forward voltage drop (Vf) at rated current determines power dissipation and thermal performance. Substitutes with comparable or lower Vf values maintain equivalent efficiency.

Recovery Speed: All qualified substitutes operate at standard recovery speeds (>500 ns, >200 mA), ensuring compatibility with standard rectification applications.

Reverse Leakage Current: Leakage characteristics at rated voltage must be controlled to prevent excessive standby current draw.

Mounting and Packaging: Through-hole axial or radial configurations are acceptable for direct substitution in PCB layouts designed for DO-15 or DO-204AC packages.

Product Status and Compliance: Active product status with RoHS3 compliance and REACH unaffected status ensures long-term availability and regulatory compliance for new designs.

Engineering Selection Recommendations

GI1-1600GP-E3/54 and GI1-1600GP-E3/73 (Vishay General Semiconductor): These diodes are recommended as primary substitutes for the CR2-160 TR. Both parts maintain identical voltage ratings (1600 V), matching forward voltage characteristics (1.1 V @ 1 A), equivalent reverse leakage (10 µA @ 1600 V), and identical operating temperature range (-65 to 175 °C). Both are active products with ROHS3 compliance and REACH unaffected status, ensuring long-term availability and regulatory compliance. The GI1 series operates under the SUPERECTIFIER® designation. Current rating is 1 A, which is lower than the CR2-160 TR's 2 A rating; selection depends on application current requirements. Axial DO-15 packaging provides direct mechanical compatibility with existing PCB layouts.

DSA1-16D (IXYS): This diode qualifies as an electrical substitute based on matching 1600 V voltage rating and standard recovery speed. The DSA1-16D provides higher current capacity (2.3 A), exceeding the CR2-160 TR's 2 A rating. However, forward voltage is elevated (1.34 V @ 7 A) and reverse leakage is significantly higher (700 µA @ 1600 V) compared to the main part. Operating temperature range is narrower (-40 to 150 °C). Radial package configuration may require PCB layout modification. The DSA1-16D is an active product with ROHS3 compliance. Selection of this substitute is appropriate only when higher current capacity is required and elevated leakage current is acceptable for the application.

Product Status Consideration: The CR2-160 TR is obsolete. All three substitute parts are active products, ensuring continued availability for new production and design revisions.

Frequently Asked Questions (FAQ)

Q: Can GI1-1600GP-E3/54 or GI1-1600GP-E3/73 be used as direct replacements for CR2-160 TR?

A: Yes, with current rating verification. Both Vishay diodes maintain identical voltage (1600 V), forward voltage (1.1 V @ 1 A), reverse leakage (10 µA @ 1600 V), and operating temperature range (-65 to 175 °C). The GI1 series is rated for 1 A average rectified current, compared to the CR2-160 TR's 2 A rating. Direct substitution is valid for applications requiring 1 A or less. For applications requiring 2 A, current capacity must be verified against actual circuit demands.

Q: What is the difference between GI1-1600GP-E3/54 and GI1-1600GP-E3/73?

A: Both parts are electrically and mechanically identical. The suffix designations (/54 and /73) indicate different packaging or tape configurations (Cut Tape). Electrical specifications, temperature range, and performance characteristics are equivalent. Selection between these two is based on procurement and packaging requirements only.

Q: Why is the DSA1-16D listed as a substitute if it has higher reverse leakage?

A: The DSA1-16D meets the core substitution criteria: 1600 V voltage rating, through-hole mounting, and standard recovery speed. Higher reverse leakage (700 µA vs. 10 µA) and elevated forward voltage are trade-offs. This substitute is appropriate for applications where leakage current is not a critical constraint and higher current capacity (2.3 A) is beneficial.

Q: Can I use a radial package diode (DSA1-16D) in a circuit designed for axial package (CR2-160 TR)?

A: Radial and axial packages have different lead configurations and PCB footprints. Mechanical substitution requires PCB layout modification. Electrical compatibility is independent of package style. Verify PCB design flexibility before selecting the DSA1-16D.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. GI1-1600GP-E3/54, GI1-1600GP-E3/73, and DSA1-16D are all ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for new designs and production.

Q: What is the temperature range difference between CR2-160 TR and DSA1-16D?

A: The CR2-160 TR operates from -65 to 175 °C. The DSA1-16D operates from -40 to 150 °C. The DSA1-16D has a narrower operating range, with a higher minimum temperature (-40 °C vs. -65 °C) and lower maximum temperature (150 °C vs. 175 °C). Verify application temperature requirements before selecting this substitute.
