Engineering Selection Recommendations

All substitute parts listed are Active product status and comply with RoHS3 and REACH regulations, matching the compliance profile of the CMPD2003 BK. Selection among substitute parts is determined by packaging format and application-specific requirements:

onsemi BAS20 Series (BAS20LT1G, BAS20LT3G, SBAS20LT1G): Available in Cut Tape and Tape & Reel packaging formats with high inventory availability. These parts are suitable for standard commercial applications.

Vishay BAS21 Series (BAS21-E3-08, BAS21-E3-18): Available in Cut Tape packaging with specified reverse leakage current at 200 V, matching the CMPD2003 BK specification exactly. Suitable for applications requiring precise leakage current control.

onsemi NSVBAS20LT3G: Qualified to AEC-Q101 automotive standard with Automotive grade designation. Appropriate for automotive and high-reliability applications. Capacitance specification not provided in available data.

Operating temperature range differs between manufacturers: CMPD2003 BK operates from -65°C to 150°C, while all substitute parts operate from -55°C to 150°C. This difference must be evaluated for applications requiring operation below -55°C.

Frequently Asked Questions (FAQ)

Q: Can BAS20LT1G replace CMPD2003 BK in all applications?

A: BAS20LT1G meets all electrical and mechanical parameter requirements for substitution. The operating temperature range differs: BAS20LT1G operates from -55°C to 150°C versus CMPD2003 BK at -65°C to 150°C. Substitution is valid for applications within the -55°C to 150°C range.

Q: What is the difference between BAS20LT1G and BAS20LT3G?

A: Both parts are electrically identical. The difference is packaging format: BAS20LT1G is supplied in Cut Tape (CT) & Digi-Reel format, while BAS20LT3G is supplied in Tape & Reel (TR) format. Selection depends on manufacturing process requirements.

Q: Is NSVBAS20LT3G suitable for automotive applications?

A: NSVBAS20LT3G is qualified to AEC-Q101 automotive standard and carries Automotive grade designation. It is appropriate for automotive and high-reliability applications. Capacitance specification is not provided in available data.

Q: Why do some substitute parts specify reverse leakage current at 150 V instead of 200 V?

A: BAS20 series parts from onsemi specify reverse leakage current at 150 V (100 nA @ 150 V), while CMPD2003 BK and Vishay BAS21 series specify at 200 V (100 nA @ 200 V). Both specifications meet the electrical requirement of 100 nA maximum leakage current within their respective measurement conditions.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All substitute parts listed are RoHS3 compliant and REACH unaffected, matching the compliance status of CMPD2003 BK.

Q: Can I use BAS21-E3-18 in place of BAS21-E3-08?

A: Both BAS21 variants are electrically identical and meet all substitution criteria. The difference is packaging format: BAS21-E3-08 is supplied in Cut Tape (CT) & Digi-Reel format, while BAS21-E3-18 is supplied in Cut Tape (CT) format. Selection depends on manufacturing process requirements.

Q: What is the moisture sensitivity level for all parts?

A: All parts, including CMPD2003 BK and all substitute parts, have Moisture Sensitivity Level (MSL) 1 (Unlimited), indicating no moisture sensitivity restrictions.
