Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the CMPD2004S BK PBFREE are qualified based on the following criteria:

Electrical Parameters (Must Match):

• Diode Configuration: 1 Pair Series Connection
• Voltage - DC Reverse (Vr) (Max): 240 V
• Current - Average Rectified (Io) (per Diode): 225 mA (DC)
• Voltage - Forward (Vf) (Max) @ If: 1 V @ 100 mA
• Speed: Fast Recovery ≤ 500ns, > 200mA (Io)
• Reverse Recovery Time (trr): 50 ns
• Current - Reverse Leakage @ Vr: 100 nA @ 240 V

Mechanical Parameters (Must Match):

• Package / Case: TO-236-3, SC-59, SOT-23-3
• Mounting Type: Surface Mount

Compliance Parameters (Must Match):

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

All identified substitutes meet these criteria and are manufactured by Vishay General Semiconductor - Diodes Division. Packaging format (Bulk, Tape & Reel, Cut Tape) and product status variations do not affect electrical or mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Active Status):

GSD2004S-E3-08 and GSD2004S-E3-18 are functionally equivalent to CMPD2004S BK PBFREE with Active product status. Both parts maintain identical electrical specifications and mechanical packaging. Selection between these two substitutes depends on packaging format availability: GSD2004S-E3-08 is supplied in Tape & Reel format, while GSD2004S-E3-18 is supplied in Cut Tape format. Both are RoHS3 compliant with MSL 1 rating.

Secondary Substitute (Automotive Grade, Last Time Buy Status):

GSD2004S-HE3-08 is electrically and mechanically equivalent but carries Last Time Buy product status and includes Automotive grade qualification with AEC-Q101 certification. This part is suitable for applications requiring automotive-grade components but should be evaluated for long-term availability due to its Last Time Buy designation.

All three substitutes are manufactured by Vishay General Semiconductor - Diodes Division and meet the compliance requirements of the original CMPD2004S BK PBFREE component.

Frequently Asked Questions (FAQ)

Q: Can GSD2004S-E3-08, GSD2004S-E3-18, and GSD2004S-HE3-08 be used interchangeably with CMPD2004S BK PBFREE?

A: Yes. All three Vishay parts are electrically and mechanically equivalent. They share identical diode configuration, voltage ratings (240 V DC reverse), current ratings (225 mA per diode), forward voltage characteristics, recovery time specifications, and package type (SOT-23-3). Differences in packaging format (Tape & Reel vs. Cut Tape) and product status do not affect circuit performance.

Q: What is the difference between GSD2004S-E3-08 and GSD2004S-E3-18?

A: The primary difference is packaging format. GSD2004S-E3-08 is supplied in Tape & Reel (TR) format, while GSD2004S-E3-18 is supplied in Cut Tape (CT) format. Electrical specifications and mechanical package dimensions are identical. Selection depends on assembly process requirements and inventory management preferences.

Q: Why is GSD2004S-HE3-08 marked as Last Time Buy?

A: Last Time Buy status indicates the manufacturer is discontinuing this part number. While currently available in inventory (35,363 pcs), future availability is limited. GSD2004S-HE3-08 is suitable for current production but should not be selected for new long-term designs unless automotive qualification is a mandatory requirement.

Q: Does GSD2004S-HE3-08 automotive qualification affect compatibility?

A: No. Automotive qualification (AEC-Q101) represents additional testing and quality assurance beyond standard requirements. The electrical and mechanical specifications remain identical to non-automotive variants. Automotive-qualified parts are compatible with non-automotive applications.

Q: Are all substitutes RoHS3 compliant?

A: Yes. CMPD2004S BK PBFREE and all three Vishay substitutes (GSD2004S-E3-08, GSD2004S-E3-18, GSD2004S-HE3-08) are RoHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating.

Q: Can these diode arrays be used in high-temperature applications?

A: All parts support operating junction temperatures up to 150°C maximum. CMPD2004S BK PBFREE specifies -65°C to 150°C range. Vishay substitutes specify 150°C maximum. Verify application requirements against these temperature limits.

Q: What is the significance of the SOT-23-3 package designation?

A: SOT-23-3 is the industry-standard surface mount package for this diode array configuration. All qualified substitutes use this identical package, ensuring PCB footprint compatibility, solder reflow process compatibility, and mechanical fit without design changes.
