Key Parameters

Substitute Part Grouping Explanation

Substitution of the TC4468MJD is determined by strict equivalence across the following critical parameters:

• Driven configuration (Low-Side)
• Number of independent drivers (4)
• Gate type compatibility (N-Channel, P-Channel MOSFET)
• Supply voltage range (4.5V ~ 18V)
• Logic voltage thresholds (VIL 0.8V, VIH 2.4V)
• Peak output current specifications (1.2A source, 1.2A sink)
• Input signal type (Non-Inverting)
• Rise and fall time characteristics (15ns typical)
• Through-hole mounting configuration
• Regulatory compliance (ROHS3, REACH Unaffected)

The TC4468EPD qualifies as a direct substitute based on matching all critical electrical and functional parameters. The primary distinction is packaging format and product status.

Parameter Comparison

Engineering Selection Recommendations

The TC4468EPD is the qualified substitute for the obsolete TC4468MJD. Both components maintain identical electrical specifications, functional characteristics, and regulatory compliance status. The TC4468EPD carries active product status, ensuring continued availability and manufacturing support from Microchip Technology.

The operating temperature range of the TC4468EPD extends to -40°C minimum, compared to -55°C for the TC4468MJD. Applications requiring operation below -40°C must retain the TC4468MJD or identify alternative solutions. For standard industrial and commercial temperature ranges, the TC4468EPD provides full functional equivalence.

Both components are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component manufacturing and distribution.

Frequently Asked Questions (FAQ)

Q: Can TC4468EPD directly replace TC4468MJD in existing designs?

A: Yes, the TC4468EPD provides direct electrical and functional equivalence. Both components share identical supply voltage ranges, output current specifications, logic thresholds, and timing characteristics. PCB layout compatibility is maintained due to identical through-hole pin configurations and 14-pin DIP package dimensions.

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

A: Both designations refer to 14-pin dual inline packages with 0.300-inch (7.62mm) row spacing. The CDIP designation indicates ceramic material, while DIP indicates the standard plastic dual inline package format. Pin spacing and footprint dimensions are identical, ensuring mechanical and electrical compatibility.

Q: Are there temperature range limitations when substituting TC4468MJD with TC4468EPD?

A: The TC4468EPD operates from -40°C to 150°C, while the TC4468MJD operates from -55°C to 150°C. Applications requiring operation below -40°C junction temperature must use the TC4468MJD or identify alternative gate driver solutions.

Q: Do both parts meet the same regulatory compliance standards?

A: Yes. Both TC4468MJD and TC4468EPD are ROHS3 compliant and REACH unaffected. Moisture sensitivity level is identical at MSL 1 (unlimited), indicating no moisture-related handling restrictions.

Q: What is the primary reason to transition from TC4468MJD to TC4468EPD?

A: The TC4468MJD is classified as obsolete, limiting long-term availability and manufacturing support. The TC4468EPD maintains active product status, ensuring continued supply chain access and technical support from Microchip Technology.
