TC4404MJA Equivalent & Substitute Parts

Part Overview

The TC4404MJA is a low-side gate driver IC manufactured by Microchip Technology, designed for driving IGBT and MOSFET gates in power management applications. This component operates with a supply voltage range of 4.5V to 18V and features independent dual-channel configuration with inverting input logic. The TC4404MJA is classified as obsolete, making identification of compatible substitute parts essential for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TC4404MJA is determined by strict alignment with the following critical parameters:

• Driven Configuration: Low-Side (mandatory match)
• Number of Drivers: 2 (mandatory match)
• Gate Type: IGBT, N-Channel, P-Channel MOSFET (mandatory match)
• Voltage - Supply: 4.5V ~ 18V (mandatory match)
• Logic Voltage - VIL, VIH: 0.8V, 2.4V (mandatory match)
• Current - Peak Output (Source, Sink): 1.5A, 1.5A (mandatory match)
• Input Type: Inverting (mandatory match)
• Rise / Fall Time (Typ): 40ns, 40ns (Max) (mandatory match)
• RoHS Status: ROHS3 Compliant (mandatory match)
• Moisture Sensitivity Level (MSL): 1 (Unlimited) (mandatory match)

The TC4404EPA qualifies as a direct substitute based on complete alignment with all mandatory electrical and compliance parameters. Variations in operating temperature range and package type do not affect functional substitution within the specified electrical operating envelope.

Parameter Comparison

Engineering Selection Recommendations

The TC4404EPA is the qualified substitute for the obsolete TC4404MJA. Both components share identical electrical specifications, functional characteristics, and regulatory compliance status (ROHS3 Compliant, REACH Unaffected). The TC4404EPA maintains active product status with Microchip Technology, ensuring continued availability and supply chain reliability.

The operating temperature range difference (-55°C ~ 125°C for TC4404MJA versus -40°C ~ 85°C for TC4404EPA) does not impact substitution for applications operating within the TC4404EPA's specified temperature envelope. Package designation differences (8-CDIP versus 8-DIP) reflect supplier nomenclature variations for equivalent through-hole DIP packaging with identical 0.300" (7.62mm) pitch specifications.

Frequently Asked Questions (FAQ)

Q: Can TC4404EPA directly replace TC4404MJA in existing designs?

A: Yes. The TC4404EPA provides electrical and functional equivalence across all critical parameters: dual-channel low-side gate driver configuration, identical supply voltage range (4.5V ~ 18V), matching output current specifications (1.5A source/sink), and identical logic voltage thresholds. Both components feature inverting input logic and 40ns rise/fall time characteristics.

Q: What is the difference between 8-CDIP and 8-DIP packaging?

A: Both designations refer to through-hole dual inline packages with 0.300" (7.62mm) pitch. The nomenclature difference reflects manufacturer supplier package naming conventions. Physical dimensions and pin spacing are equivalent, permitting direct PCB footprint compatibility.

Q: Does the operating temperature range difference affect substitution?

A: The TC4404EPA operating range (-40°C ~ 85°C) is narrower than the TC4404MJA (-55°C ~ 125°C). Substitution is valid only for applications operating within the TC4404EPA's specified temperature envelope. Applications requiring operation below -40°C or above 85°C require alternative component selection.

Q: Are compliance certifications identical between both parts?

A: Yes. Both TC4404MJA and TC4404EPA maintain ROHS3 Compliance, REACH Unaffected status, and Moisture Sensitivity Level 1 (Unlimited) classification. Regulatory and environmental compliance requirements are satisfied by either component.

Q: What is the inventory status for these components?

A: TC4404MJA (obsolete status): 1008 pieces available. TC4404EPA (active status): 885 pieces available. The active status of TC4404EPA ensures continued procurement capability for future requirements.
