Substitute Part Grouping Explanation

Substitution of the CD214A-B160LF is determined by strict equivalence across the following electrical and mechanical parameters:

Primary Substitution Criteria:

Voltage - DC Reverse (Vr) (Max): 60 V
Current - Average Rectified (Io): 1 A
Voltage - Forward (Vf) (Max) @ If: 700 mV @ 1 A (±50 mV tolerance acceptable)
Speed: Fast Recovery ≤ 500ns, > 200mA (Io)
Current - Reverse Leakage @ Vr: 500 µA @ 60 V (±100 µA acceptable)
Capacitance @ Vr, F: 110pF @ 4V, 1MHz (±20pF acceptable)
Mounting Type: Surface Mount
Package / Case: DO-214AC, SMA
Technology: Schottky

Direct Equivalent (Same Manufacturer, Different Packaging): CD214A-B160R meets all electrical specifications with identical performance characteristics. The difference is packaging format (2-SMD vs. DO-214AC), maintaining full functional equivalence.

Cross-Manufacturer Equivalents (Active Status): Parts meeting all primary criteria with active product status include B160-13-F (Diodes Incorporated), B160Q-13-F (Diodes Incorporated), CDBA160-G (Comchip Technology), SS16-E3/5AT (Vishay), and SS16-LTP (Micro Commercial Co). These maintain electrical parity with the original specification.

Similar Parts (Modified Parameters): Parts with variations in reverse leakage current, forward voltage, or operating temperature range are classified as similar but not direct equivalents. These include B160-E3/61T (Vishay), CDBA260-HF (Comchip Technology - 2A rated), RB068L-60TE25 (Rohm - 2A rated), and RB162L-60TE25 (Rohm - 1A rated). Selection requires verification that parameter deviations do not impact circuit performance.

Engineering Selection Recommendations

Tier 1 - Direct Equivalents (Recommended for Replacement):

CD214A-B160R (Bourns Inc.) is the primary direct equivalent, maintaining identical electrical specifications and operating temperature range. This part is active and available in high volume (12,400 pcs), providing seamless substitution with only packaging format differences.

B160-13-F (Diodes Incorporated) and B160Q-13-F (Diodes Incorporated) are functionally equivalent with extended operating temperature range (-65°C ~ 150°C vs. -55°C ~ 125°C). B160Q-13-F includes AEC-Q101 automotive qualification. Both are active with substantial inventory availability (245,300 pcs and 55,300 pcs respectively).

CDBA160-G (Comchip Technology) meets all electrical specifications with active product status and high inventory (88,893 pcs). Operating temperature extends to -65°C ~ 150°C.

SS16-LTP (Micro Commercial Co) provides electrical equivalence with active status and extended upper operating temperature (150°C). Inventory is substantial (55,100 pcs).

Tier 2 - Compatible Alternatives (Parameter Variations):

B160-E3/61T (Vishay) and SS16-E3/5AT (Vishay) feature forward voltage of 750 mV @ 1 A (50 mV higher than original) and reduced reverse leakage (200 µA @ 60 V). Extended operating temperature range (-65°C ~ 150°C) is provided. These are suitable where lower leakage current is beneficial.

RB162L-60TE25 (Rohm Semiconductor) offers 1 A rating with reduced forward voltage (650 mV @ 1 A) and significantly lower reverse leakage (100 µA @ 60 V). Product status is "Not For New Designs," limiting suitability for new applications.

Tier 3 - Higher Current Alternatives (Not Recommended for Direct Substitution):

CDBA260-HF (Comchip Technology) and RB068L-60TE25 (Rohm Semiconductor) are rated for 2 A average rectified current. These are oversized for 1 A applications and introduce unnecessary cost and board space considerations. RB068L-60TE25 carries "Not For New Designs" status.

Compliance Considerations:

All recommended Tier 1 alternatives are ROHS3 compliant with MSL 1 (Unlimited). REACH status varies: Bourns parts are REACH Affected; Diodes Incorporated, Comchip Technology, Vishay, and Micro Commercial Co parts are REACH Unaffected. Selection should account for supply chain REACH compliance requirements.

Frequently Asked Questions (FAQ)

Q: Can CD214A-B160R replace CD214A-B160LF directly?

A: Yes. CD214A-B160R is a direct electrical equivalent from the same manufacturer (Bourns Inc.) with identical specifications. The difference is packaging format: CD214A-B160R uses 2-SMD configuration while CD214A-B160LF uses DO-214AC (SMA). Both are surface mount and compatible with standard PCB layouts for SMA packages.

Q: What is the difference between B160-13-F and B160Q-13-F?

A: Both are manufactured by Diodes Incorporated and meet the electrical specifications of the original part. B160Q-13-F includes AEC-Q101 automotive qualification and is supplied on Tape & Reel (TR). B160-13-F is supplied on Cut Tape (CT) & Digi-Reel®. Electrical performance is identical. Selection depends on packaging format and automotive qualification requirements.

Q: Why do some substitute parts have different forward voltage specifications?

A: Forward voltage variation (700 mV vs. 750 mV @ 1 A) reflects manufacturing process differences between suppliers. Both values remain within acceptable Schottky diode performance ranges for 60 V, 1 A applications. Circuit designs with tight voltage regulation requirements should verify compatibility with the specific forward voltage of the selected part.

Q: Can I use CDBA260-HF (2 A rated) instead of the 1 A original part?

A: CDBA260-HF is electrically compatible but rated for 2 A average rectified current. Using a higher-rated component in a 1 A application is permissible from an electrical standpoint; however, it introduces unnecessary cost and may occupy additional board space. Direct 1 A equivalents (B160-13-F, CDBA160-G, SS16-LTP) are preferred for cost optimization.

Q: What is the significance of "Not For New Designs" status on Rohm parts?

A: Parts marked "Not For New Designs" (RB068L-60TE25, RB162L-60TE25) indicate that the manufacturer is discontinuing these products and recommends alternative components for new circuit designs. These parts may be used for legacy system support or repair but should not be selected for new product development.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All substitute parts listed are ROHS3 compliant. However, REACH status differs: Bourns parts are REACH Affected, while Diodes Incorporated, Comchip Technology, Vishay, and Micro Commercial Co parts are REACH Unaffected. Verify REACH compliance requirements for your supply chain before final part selection.

Q: What is the difference between DO-214AC and 2-SMD packaging?

A: Both are surface mount packages for Schottky diodes. DO-214AC (SMA) is a standard industry package with defined footprint dimensions. 2-SMD refers to a two-lead surface mount configuration. Both are compatible with automated PCB assembly equipment. Verify PCB footprint compatibility with your specific design before substitution.

Q: Can I substitute based on reverse voltage alone?

A: No. Reverse voltage is one of multiple critical parameters. Current rating, forward voltage, reverse leakage, and operating temperature must also match or be compatible with circuit requirements. Substitution requires verification across all electrical and thermal specifications.

Q: Why is reverse leakage current specified at different voltages for some parts?

A: Reverse leakage current is voltage-dependent. B160Q-13-F specifies leakage at 40 V while most others specify at 60 V. For applications operating at 60 V, the 40 V specification does not provide complete information. Request 60 V leakage data from the manufacturer if this parameter is critical to circuit performance.

Q: What is the operating temperature range significance?

A: The original CD214A-B160LF operates from -55°C to 125°C junction temperature. Most substitute parts extend this to -65°C to 150°C, providing wider thermal margin. If your application operates within the original range, this difference is not significant. For applications requiring extended temperature operation, the wider range of substitute parts is beneficial.
