Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Identical Electrical Performance):

CDBB260-HF is the primary direct substitute. It maintains identical electrical specifications (60V/2A, 700mV forward voltage, 500µA reverse leakage) and DO-214AA packaging. The part is manufactured by the same supplier (Comchip Technology) and carries Active product status, eliminating obsolescence risk. Operating temperature range extends to 150°C maximum, providing thermal margin over the original -55°C to 125°C specification.

For Active Product Status with Extended Temperature Range:

B260-13-F (Diodes Incorporated) meets all primary electrical and mechanical criteria with identical 60V/2A ratings and 700mV forward voltage. This part offers extended junction temperature range (-65°C to 150°C), providing superior thermal performance. RoHS3 compliance and REACH compliance are maintained. Active product status ensures long-term availability.

For Automotive-Grade Applications:

SK26HE3-LTP and STPS3L60UY both carry AEC-Q101 automotive qualification. SK26HE3-LTP maintains exact 60V/2A specifications with 700mV forward voltage. STPS3L60UY provides 3A current rating with lower forward voltage (620mV @ 3A) and superior reverse leakage characteristics (150µA vs. 500µA), suitable for applications requiring enhanced performance margin.

For Applications Requiring Current Margin:

SK36B-LTP and STPS3L60UY provide 3A average rectified current at 60V reverse voltage, exceeding the 2A requirement. Both maintain DO-214AA packaging and fast recovery characteristics. STPS3L60UY offers lower forward voltage (620mV @ 3A) and automotive qualification (AEC-Q101).

For Current-Limited Applications:

STPS160U and STPS160UY are rated for 1A average rectified current. These parts are suitable only for applications where circuit design permits reduced current capacity. STPS160UY carries AEC-Q101 automotive qualification and extended temperature range (-40°C to 150°C).

Compliance and Certification:

All substitute parts maintain RoHS3 compliance and MSL 1 (Unlimited) moisture sensitivity level. Parts designated with automotive grade (SK26HE3-LTP, STPS3L60UY, STPS160UY) carry AEC-Q101 qualification, suitable for automotive and high-reliability applications.

Frequently Asked Questions (FAQ)

Q: Can CDBB260-HF be used as a direct replacement for CDBB260-G?

A: Yes. CDBB260-HF is a direct parametric equivalent manufactured by Comchip Technology. It maintains identical electrical specifications (60V reverse voltage, 2A average rectified current, 700mV forward voltage @ 2A, ≤500ns fast recovery) and DO-214AA packaging. The primary advantage is Active product status versus Not For New Designs status of the original part. Operating temperature range extends to 150°C maximum.

Q: What is the difference between SS26B-HF and SK26-LTP?

A: Both parts meet the 60V/2A electrical specifications and DO-214AA packaging requirements. SS26B-HF is manufactured by Comchip Technology with 500µA reverse leakage @ 60V. SK26-LTP is manufactured by Micro Commercial Co with higher reverse leakage (1mA @ 60V). Both maintain -55°C to 125°C operating temperature range. Selection depends on supplier preference and reverse leakage tolerance in the application.

Q: Can I use STPS3L60UY (3A) instead of CDBB260-G (2A)?

A: Yes, with design consideration. STPS3L60UY is rated for 3A average rectified current at 60V, exceeding the 2A requirement. It maintains DO-214AA packaging and fast recovery characteristics (≤500ns). Forward voltage is lower (620mV @ 3A vs. 700mV @ 2A), and reverse leakage is lower (150µA vs. 500µA). The part carries AEC-Q101 automotive qualification. This substitution provides performance margin and is suitable for applications where enhanced current capacity is beneficial or neutral.

Q: Why would I choose STPS160UY over CDBB260-G?

A: STPS160UY should be selected only if circuit design permits reduced current capacity (1A vs. 2A). This part offers superior reverse leakage characteristics (4µA @ 60V vs. 500µA) and extended temperature range (-40°C to 150°C). It carries AEC-Q101 automotive qualification. Use this part only when application current requirements are confirmed at 1A or below.

Q: Are all substitute parts available in the same packaging?

A: All listed substitute parts use DO-214AA (SMB) surface mount packaging, maintaining mechanical compatibility with CDBB260-G. Mounting footprints and PCB layout remain unchanged. Verify supplier device package designation (some suppliers designate as "SMB" or "DO-214AA, HSMB") to confirm mechanical compatibility with existing designs.

Q: What is the significance of AEC-Q101 qualification?

A: AEC-Q101 is an automotive industry qualification standard for discrete semiconductors. Parts carrying this qualification (SK26HE3-LTP, STPS3L60UY, STPS160UY) have undergone rigorous testing for automotive applications, including thermal cycling, vibration, and reliability assessment. These parts are suitable for automotive and high-reliability industrial applications where enhanced qualification is required.

Q: Can I mix different substitute parts in the same production run?

A: All listed substitute parts meet the primary electrical specifications (60V reverse voltage, 2A average rectified current, 700mV forward voltage, fast recovery ≤500ns, DO-214AA packaging). However, reverse leakage characteristics vary (4µA to 1mA @ 60V). For applications sensitive to reverse leakage or requiring consistent performance characteristics, maintain single-part selection within a production batch. Consult application circuit requirements to determine if reverse leakage variation is acceptable.

Q: What is the difference between Cut Tape (CT) and Tape & Reel (TR) packaging?

A: Both are surface mount delivery formats. Tape & Reel (TR) is supplied on continuous carrier tape wound on reels, suitable for high-volume automated assembly. Cut Tape (CT) is supplied as individual tape segments, suitable for lower-volume or manual assembly operations. Electrical and mechanical specifications are identical; selection depends on assembly process and volume requirements.

Q: Is CDBB260-G still available for purchase?

A: CDBB260-G is classified as "Not For New Designs" with 12,900 pieces in stock. While current inventory exists, this classification indicates end-of-life status and declining availability. For new designs or long-term production support, selection of an Active-status substitute (CDBB260-HF, B260-13-F, SK26-LTP, or STPS3L60UY) is recommended to ensure sustained supply.
