CDBA160LR-HF Schottky Diode Equivalent & Substitute Parts

Part Overview

The CDBA160LR-HF is a surface mount Schottky rectifier diode manufactured by Comchip Technology, rated for 60V DC reverse voltage and 1A average rectified current in a DO-214AC (SMA) package. This component is classified as Active product status and is fully RoHS3 compliant with REACH unaffected designation.

Substitute parts become necessary when the primary part experiences supply constraints, extended lead times, or when design requirements permit alternative manufacturers meeting identical electrical and mechanical specifications. The CDBA160LR-HF has documented substitute availability through Rohm Semiconductor's RB162L-60TE25, which maintains electrical parameter compatibility within the allowed operating range.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CDBA160LR-HF is determined by strict alignment of the following critical parameters:

Electrical Parameters (Must Match Exactly):

• Voltage - DC Reverse (Vr) (Max): 60V
• Current - Average Rectified (Io): 1A
• Speed Classification: Fast Recovery ≤ 500ns, > 200mA (Io)
• Technology: Schottky

Mechanical Parameters (Must Match Exactly):

• Package / Case: DO-214AC, SMA
• Mounting Type: Surface Mount

Compliance Parameters (Must Match or Exceed):

• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Performance Parameters (Allowed Variance):

• Voltage - Forward (Vf) (Max) @ If: Substitute may vary within circuit design tolerance
• Current - Reverse Leakage @ Vr: Substitute may vary within circuit design tolerance
• Operating Temperature - Junction: Substitute must support application range

The RB162L-60TE25 from Rohm Semiconductor qualifies as a direct substitute based on matching all critical electrical and mechanical parameters, despite differences in forward voltage (650 mV vs. 550 mV) and reverse leakage current (100 µA vs. 500 µA), which remain within acceptable engineering variance for Schottky diode applications.

Engineering Selection Recommendations

Primary Selection: CDBA160LR-HF

The CDBA160LR-HF maintains Active product status, indicating ongoing manufacturer support, continued availability, and suitability for new design implementations. This part is the preferred choice for new applications and long-term production requirements.

Substitute Selection: RB162L-60TE25

The RB162L-60TE25 qualifies as an electrical and mechanical equivalent based on matching critical parameters: 60V reverse voltage rating, 1A average rectified current, fast recovery switching speed, and DO-214AC surface mount package. Both parts maintain ROHS3 compliance and MSL Level 1 designation.

The RB162L-60TE25 carries "Not For New Designs" status, restricting its use to replacement, repair, or legacy system applications where the original part is unavailable. The forward voltage differential (650 mV vs. 550 mV at 1A) represents a 100 mV increase, which must be evaluated within specific circuit thermal and efficiency requirements. The improved reverse leakage characteristic (100 µA vs. 500 µA) presents a performance advantage in low-current standby applications.

Selection Criteria:

• New designs: Use CDBA160LR-HF
• Replacement/repair of existing systems: RB162L-60TE25 is acceptable when CDBA160LR-HF is unavailable
• Thermal-sensitive applications: Evaluate forward voltage impact on power dissipation
• Low-leakage applications: RB162L-60TE25 offers superior reverse leakage performance

Frequently Asked Questions (FAQ)

Q: Can RB162L-60TE25 be used as a direct replacement for CDBA160LR-HF in new designs?

A: No. While RB162L-60TE25 meets all critical electrical and mechanical parameters, its "Not For New Designs" status restricts use to replacement applications only. CDBA160LR-HF is the specified component for new design implementations.

Q: What is the significance of the 100 mV forward voltage difference between these parts?

A: The RB162L-60TE25 exhibits 650 mV forward voltage at 1A compared to 550 mV for CDBA160LR-HF. This 100 mV increase results in higher power dissipation in the diode. Circuit designers must verify that thermal management and efficiency specifications remain within acceptable limits for the specific application.

Q: Are both parts mechanically compatible with the same PCB footprint?

A: Yes. Both CDBA160LR-HF and RB162L-60TE25 use the DO-214AC (SMA) surface mount package, ensuring identical PCB footprint and assembly process compatibility without layout modifications.

Q: What does "Not For New Designs" mean for the RB162L-60TE25?

A: This designation indicates that Rohm Semiconductor does not recommend this part for new product development. The part remains available for replacement and repair of existing systems. New designs should specify CDBA160LR-HF or evaluate alternative current-generation Schottky diodes from the manufacturer's active product portfolio.

Q: Do both parts meet the same regulatory compliance requirements?

A: Yes. Both CDBA160LR-HF and RB162L-60TE25 are ROHS3 compliant, REACH unaffected, and carry MSL Level 1 (Unlimited) moisture sensitivity designation, meeting identical regulatory and handling requirements.

Q: What is the difference in reverse leakage current, and does it matter?

A: RB162L-60TE25 exhibits 100 µA reverse leakage at 60V, compared to 500 µA for CDBA160LR-HF. The lower leakage in RB162L-60TE25 provides improved performance in low-current standby or precision measurement applications where leakage current significantly impacts circuit behavior.

Q: Can these parts be used interchangeably in existing production?

A: Substitution in existing production requires engineering evaluation of the forward voltage and reverse leakage differences within the specific circuit context. Thermal analysis and efficiency verification are necessary before authorizing RB162L-60TE25 as a production substitute for CDBA160LR-HF.
