TC4468EJD Equivalent & Substitute Parts

Part Overview

The TC4468EJD is a low-side gate driver IC manufactured by Microchip Technology, designed for driving N-Channel and P-Channel MOSFETs in independent channel configurations. This device operates with a supply voltage range of 4.5V to 18V and delivers peak output currents of 1.2A for both source and sink operations.

The TC4468EJD is classified as obsolete. Identifying equivalent substitute parts is necessary to maintain design continuity and ensure component availability for new production runs, repairs, and system upgrades where this device is specified.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TC4468EJD is determined by strict equivalence across the following critical parameters:

• Driven configuration: Low-side operation
• Number of independent drivers: 4 channels
• Gate type compatibility: N-Channel and P-Channel MOSFET support
• Supply voltage range: 4.5V ~ 18V
• Logic voltage thresholds: VIL 0.8V, VIH 2.4V
• Peak output current capability: 1.2A source and sink
• Input signal type: Non-inverting
• Rise and fall time characteristics: 15ns typical
• Operating temperature range: -40°C ~ 150°C
• Base product number: TC4468
• Regulatory compliance: ROHS3, REACH Unaffected

The TC4468EPD qualifies as a direct substitute based on identical electrical specifications and functional characteristics. The primary difference is packaging format and product status.

Parameter Comparison

Engineering Selection Recommendations

The TC4468EPD is the manufacturer-recommended substitute for the obsolete TC4468EJD. Both devices share identical electrical specifications, functional characteristics, and regulatory compliance status (ROHS3 Compliant, REACH Unaffected).

The TC4468EPD maintains active product status with Microchip Technology, ensuring ongoing availability and support. The packaging difference between 14-CDIP and 14-DIP formats does not affect electrical performance, as both are through-hole mounted devices with identical 0.300" (7.62mm) pitch specifications.

Selection of the TC4468EPD is appropriate for all applications previously specified with the TC4468EJD, provided that printed circuit board layout accommodates the DIP package format.

Frequently Asked Questions (FAQ)

Q: Can the TC4468EPD directly replace the TC4468EJD in existing designs?

A: Yes. The TC4468EPD provides identical electrical performance and functional characteristics. Both devices are through-hole mounted with compatible pitch specifications. PCB layout must accommodate the 14-DIP package format.

Q: What is the difference between 14-CDIP and 14-DIP packaging?

A: Both are 14-pin through-hole packages with 0.300" (7.62mm) pitch. The primary distinction is the ceramic (CDIP) versus plastic (DIP) package material. Electrical performance and pin configuration are identical.

Q: Why is the TC4468EJD classified as obsolete?

A: The TC4468EJD has reached end-of-life status with Microchip Technology. The TC4468EPD remains in active production and is the recommended replacement.

Q: Are there any compliance differences between these parts?

A: No. Both the TC4468EJD and TC4468EPD are ROHS3 Compliant, REACH Unaffected, with MSL rating of 1 (Unlimited).

Q: What are the critical parameters for substitution?

A: Substitution is valid when the following parameters match: driven configuration (low-side), number of drivers (4), gate type (N-Channel, P-Channel MOSFET), supply voltage range (4.5V ~ 18V), logic voltage thresholds (0.8V, 2.4V), peak output current (1.2A source and sink), input type (non-inverting), and operating temperature range (-40°C ~ 150°C).
