CMPD2004A TR PBFREE Equivalent & Substitute Parts

Part Overview

The CMPD2004A TR PBFREE is a general-purpose diode array manufactured by Central Semiconductor Corp, configured as a 1 Pair Common Anode device in SOT-23 surface mount packaging. This component is rated for 240 V DC reverse voltage with 200 mA average rectified current per diode and operates across a junction temperature range of -65°C to 150°C. The part is currently in Active product status with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1).

Substitute parts are necessary when the original CMPD2004A becomes unavailable, when alternative sourcing is required for supply chain optimization, or when design requirements permit higher current ratings within the same voltage and package specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the CMPD2004A TR PBFREE is permissible with alternative diode array parts that maintain the following critical parameters:

Mandatory Matching Parameters:

• Diode Configuration: 1 Pair Common Anode
• Voltage - DC Reverse (Vr) (Max): 240 V minimum
• Package / Case: TO-236-3, SC-59, SOT-23-3 (SOT-23 surface mount)
• Mounting Type: Surface Mount
• Reverse Recovery Time (trr): 50 ns

Allowable Parameter Variations:

• Current - Average Rectified (Io): Equal to or greater than 200 mA per diode
• Voltage - Forward (Vf): Equal to or lower than 1.25 V at rated current
• Operating Temperature - Junction (Max): Equal to or greater than 150°C
• Current - Reverse Leakage @ Vr: Equal to or lower than 100 nA @ 240 V

The substitute parts GSD2004A-E3-08 and GSD2004A-HE3-08 from Vishay General Semiconductor - Diodes Division satisfy all mandatory parameters and provide enhanced current capability (225 mA per diode) within the same physical and electrical envelope.

Parameter Comparison

Engineering Selection Recommendations

GSD2004A-E3-08 Selection Criteria: This substitute is suitable for applications requiring standard commercial-grade diode arrays with enhanced current capacity. The part maintains Active product status, ensuring long-term availability and supply chain stability. ROHS3 compliance and unlimited MSL rating align with the original CMPD2004A specifications. The increased current rating of 225 mA per diode provides design margin for applications operating near the 200 mA threshold of the original part.

GSD2004A-HE3-08 Selection Criteria: This substitute is designated for automotive and mission-critical applications requiring AEC-Q101 qualification. The part carries Last Time Buy status, indicating limited future availability; selection of this part should be reserved for applications where automotive-grade certification is a mandatory requirement. The AEC-Q101 qualification provides enhanced reliability assurance for automotive and high-reliability environments. The 225 mA current rating and identical electrical parameters ensure functional equivalence with design margin.

General Selection Logic: Both substitute parts satisfy all mandatory electrical and mechanical parameters of the CMPD2004A TR PBFREE. Selection between GSD2004A-E3-08 and GSD2004A-HE3-08 depends on application requirements: standard commercial applications should prioritize GSD2004A-E3-08 for sustained availability; automotive and high-reliability applications should select GSD2004A-HE3-08 for AEC-Q101 certification, with awareness of Last Time Buy status.

Frequently Asked Questions (FAQ)

Q: Can GSD2004A-E3-08 and GSD2004A-HE3-08 be used interchangeably with CMPD2004A TR PBFREE?

A: Yes, both substitute parts are electrically and mechanically compatible with the CMPD2004A TR PBFREE. All three parts share identical diode configuration (1 Pair Common Anode), reverse voltage rating (240 V), package type (SOT-23), and reverse recovery time (50 ns). The substitute parts provide equal or superior performance in forward voltage and reverse leakage characteristics.

Q: What is the difference between GSD2004A-E3-08 and GSD2004A-HE3-08?

A: Both parts are functionally equivalent with identical electrical specifications. The primary difference is product status and qualification: GSD2004A-E3-08 is in Active status for general commercial use, while GSD2004A-HE3-08 carries AEC-Q101 automotive qualification and Last Time Buy status. Selection depends on whether automotive-grade certification is required for the application.

Q: Does the higher current rating (225 mA vs. 200 mA) of the substitute parts affect circuit compatibility?

A: No. The higher current rating of the substitute parts (225 mA per diode) is a performance enhancement that does not affect circuit compatibility. Circuits designed for 200 mA operation will function identically with 225 mA-rated parts. The higher rating provides additional design margin and thermal headroom.

Q: Are the substitute parts ROHS3 compliant?

A: Yes. Both GSD2004A-E3-08 and GSD2004A-HE3-08 are ROHS3 compliant with unlimited moisture sensitivity rating (MSL 1), matching the compliance profile of the original CMPD2004A TR PBFREE.

Q: What is the significance of Last Time Buy status for GSD2004A-HE3-08?

A: Last Time Buy status indicates that the manufacturer has announced end-of-life for this part number. While current inventory is available (36,400 pcs), future procurement will not be possible after the Last Time Buy window closes. For applications requiring long-term supply continuity, GSD2004A-E3-08 (Active status) is the preferred choice.

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

A: Yes. All three parts are rated for junction temperatures up to 150°C maximum, supporting operation in elevated-temperature environments within this thermal limit.
