Substitute Part Grouping Explanation

Substitute parts for the DMP2004TK are identified based on strict electrical and mechanical parameter compatibility. The substitution criteria are:

Primary Matching Parameters:

• FET Type: P-Channel
• Technology: MOSFET (Metal Oxide)
• Drain to Source Voltage (Vdss): 20 V (equal or greater)
• Package Type: SOT-523 (identical)
• Mounting Type: Surface Mount
• Operating Temperature Range: -55°C to 150°C (minimum requirement)

Secondary Compatibility Parameters:

• Continuous Drain Current (Id): Equal to or greater than 430 mA
• Rds On (Max): Equal to or less than 1.1 Ohm at rated conditions
• Power Dissipation (Max): Equal to or greater than 230 mW
• RoHS Compliance: ROHS3 Compliant

The PJE8407_R1_00001 from Panjit International Inc. meets all primary and secondary criteria, making it a direct functional equivalent for the DMP2004TK in applications requiring P-Channel MOSFET performance within the specified parameter envelope.

Parameter Comparison

Engineering Selection Recommendations

The PJE8407_R1_00001 is a qualified substitute for the DMP2004TK based on the following engineering criteria:

Electrical Compatibility: Both devices share identical Vdss (20 V), Vgs(th) (1 V @ 250 µA), and operating temperature range (-55°C to 150°C). The PJE8407_R1_00001 provides higher continuous drain current (500 mA versus 430 mA) and greater power dissipation capability (300 mW versus 230 mW), making it suitable for applications requiring equal or higher performance margins.

Mechanical Compatibility: Both parts utilize the SOT-523 surface mount package with identical pinout and footprint, enabling direct board-level substitution without layout modifications.

Regulatory Compliance: Both devices are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements. Both carry EAR99 ECCN classification and identical HTSUS codes (8541.21.0095).

Product Status: Both parts are in active production with confirmed inventory availability. The DMP2004TK has 17,985 units in stock, while the PJE8407_R1_00001 has 3,946 units available.

Selection between these parts should be based on application current requirements, thermal management constraints, and supply chain availability.

Frequently Asked Questions (FAQ)

Q: Can the PJE8407_R1_00001 be used as a direct replacement for the DMP2004TK in existing designs?

A: Yes. Both devices are P-Channel MOSFETs in SOT-523 packages with identical Vdss (20 V), threshold voltage, and operating temperature range. The PJE8407_R1_00001 provides higher current and power ratings, making it functionally compatible for direct substitution without circuit redesign.

Q: What are the key differences between these two parts?

A: The primary differences are continuous drain current (PJE8407_R1_00001: 500 mA versus DMP2004TK: 430 mA), maximum Rds On (PJE8407_R1_00001: 1.2 Ohm versus DMP2004TK: 1.1 Ohm), power dissipation (PJE8407_R1_00001: 300 mW versus DMP2004TK: 230 mW), and maximum gate voltage (PJE8407_R1_00001: ±10 V versus DMP2004TK: ±8 V). All other electrical and mechanical parameters are equivalent.

Q: Are there any package or pinout differences?

A: No. Both parts use the SOT-523 surface mount package with identical pinout and footprint. No PCB layout modifications are required for substitution.

Q: Do both parts meet the same regulatory standards?

A: Yes. Both the DMP2004TK and PJE8407_R1_00001 are ROHS3 compliant, REACH unaffected, and carry EAR99 ECCN classification. Both share the same HTSUS code (8541.21.0095).

Q: Which part should be selected for new designs?

A: Selection depends on application requirements. For designs requiring the minimum specified performance (430 mA, 230 mW), either part is suitable. For applications with higher current or thermal demands, the PJE8407_R1_00001 provides additional performance margin. Supply chain availability and lead time should also be considered.

Q: What is the gate charge difference between these parts?

A: The DMP2004TK has a maximum gate charge of 0.97 nC @ 8 V, while the PJE8407_R1_00001 has 1.4 nC @ 4.5 V. This difference reflects different measurement conditions and does not prevent substitution in standard switching applications.

Q: Are the input capacitance values compatible?

A: Yes. The DMP2004TK has 47 pF @ 16 V input capacitance, and the PJE8407_R1_00001 has 38 pF @ 10 V. Both values are within acceptable ranges for typical P-Channel MOSFET applications and do not present substitution barriers.
