CBRLD1-02 BK Bridge Rectifier Equivalent & Substitute Parts

Part Overview

The CBRLD1-02 BK is a single-phase bridge rectifier manufactured by Central Semiconductor Corp, rated for 200 V peak reverse voltage and 1 A average rectified current in a 4-LPDIP surface mount package. This component is classified as obsolete, making identification of compatible substitute parts essential for ongoing design support and production continuity. Equivalent parts must maintain identical electrical ratings and mechanical compatibility to ensure direct replacement without circuit redesign.

Substitute Part Grouping Explanation

Substitute parts for the CBRLD1-02 BK are qualified based on the following electrical and mechanical criteria:

Electrical Compatibility Requirements:

• Diode Type: Single Phase
• Voltage - Peak Reverse (Max): 200 V (minimum)
• Current - Average Rectified (Io): 1 A (minimum)
• Operating Temperature Range: -55°C to 150°C or wider
• Package / Case: 4-SMD, Gull Wing

Mechanical Compatibility Requirements:

• Mounting Type: Surface Mount
• Moisture Sensitivity Level: 1 (Unlimited) or equivalent

The ABS2U from SMC Diode Solutions meets all substitution criteria and is listed as the manufacturer-recommended equivalent. Additional qualified substitutes (DF02S-E3/77, DF02SA-E3/77, DF02S1) are available through the ABS2U cross-reference chain.

Parameter Comparison

Engineering Selection Recommendations

The ABS2U is the primary substitute for the obsolete CBRLD1-02 BK. Both components share identical electrical ratings (200 V, 1 A) and mechanical specifications (4-SMD Gull Wing package, surface mount). The ABS2U is currently in active production with 1147 units in stock, ensuring supply continuity.

The ABS2U demonstrates improved reverse leakage characteristics (5 µA versus 10 µA at 200 V), indicating superior device quality. Forward voltage is marginally higher (1.1 V versus 1 V at 1 A), a difference of 0.1 V that remains within typical circuit tolerance for rectifier applications.

The ABS2U carries ROHS3 compliance and REACH affected status, meeting current environmental and regulatory requirements. These certifications are not specified for the obsolete CBRLD1-02 BK.

For applications requiring additional alternatives, the DF02S-E3/77, DF02SA-E3/77, and DF02S1 are qualified substitutes accessible through the ABS2U cross-reference.

Frequently Asked Questions (FAQ)

Q: Can the ABS2U directly replace the CBRLD1-02 BK without circuit modification?

A: Yes. Both components are single-phase bridge rectifiers with identical voltage (200 V) and current (1 A) ratings, matching operating temperature ranges (-55°C to 150°C), and identical 4-SMD Gull Wing package geometry. Direct PCB substitution is possible.

Q: What is the significance of the 0.1 V difference in forward voltage between CBRLD1-02 BK and ABS2U?

A: The CBRLD1-02 BK specifies 1 V maximum forward voltage at 1 A, while the ABS2U specifies 1.1 V at the same current. This 0.1 V difference is typical between different rectifier manufacturers and does not affect circuit functionality in standard rectification applications. Verify forward voltage drop against your circuit's voltage regulation requirements.

Q: Why is the reverse leakage current lower in the ABS2U?

A: The ABS2U exhibits 5 µA reverse leakage at 200 V compared to 10 µA for the CBRLD1-02 BK. Lower reverse leakage indicates improved device quality and reduced power dissipation in reverse bias conditions. This is a beneficial characteristic and does not affect substitution compatibility.

Q: Are there packaging differences between CBRLD1-02 BK and ABS2U?

A: Both components use 4-SMD Gull Wing surface mount packages. The CBRLD1-02 BK is supplied in standard packaging, while the ABS2U is available in Tape & Reel (TR) format. Tape & Reel packaging is standard for high-volume production and does not affect component electrical or mechanical properties.

Q: What compliance certifications does the ABS2U carry?

A: The ABS2U is ROHS3 compliant and REACH affected. These certifications ensure compliance with current environmental regulations for electronic components. The obsolete CBRLD1-02 BK does not specify these certifications.

Q: Are DF02S-E3/77, DF02SA-E3/77, and DF02S1 suitable alternatives?

A: These parts are qualified substitutes accessible through the ABS2U cross-reference chain. Verify their specific electrical parameters and package specifications against your application requirements before selection.
