Key Parameters

Substitute Part Grouping Explanation

Substitution of the TC4467EJD is determined by strict equivalence across the following critical parameters:

• Base product number (TC4467 family)
• Driven configuration (Low-Side)
• Number of drivers (4 independent channels)
• 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 logic type (Inverting)
• Rise and fall time characteristics (15ns typical)
• Through-hole mounting requirement
• RoHS3 compliance and MSL rating

The TC4467CPD qualifies as a direct substitute based on identical electrical performance across all specified parameters. The primary distinction is the package type: TC4467EJD uses 14-CERDIP packaging, while TC4467CPD uses 14-PDIP packaging. Both are through-hole packages with equivalent pin configurations and mechanical compatibility in standard PCB layouts.

Parameter Comparison

Engineering Selection Recommendations

The TC4467CPD is the primary substitute for the obsolete TC4467EJD. Both devices share identical electrical specifications and are manufactured by Microchip Technology under the same base product number. The TC4467CPD maintains active product status, ensuring ongoing availability and supply chain support.

The operating temperature range differs between the two parts: TC4467EJD operates from -40°C to 150°C, while TC4467CPD operates from 0°C to 150°C. Applications requiring operation below 0°C must retain the TC4467EJD or identify alternative solutions outside the TC4467 family.

Both parts maintain ROHS3 compliance and MSL rating of 1 (Unlimited), satisfying environmental and moisture sensitivity requirements. The 14-CERDIP and 14-PDIP packages are mechanically compatible in standard through-hole PCB layouts, allowing direct substitution without circuit board redesign.

Frequently Asked Questions (FAQ)

Q: Can TC4467CPD replace TC4467EJD in all applications?

A: TC4467CPD is electrically equivalent to TC4467EJD across all specified parameters. The primary consideration is operating temperature: TC4467CPD operates from 0°C to 150°C, while TC4467EJD operates from -40°C to 150°C. Applications requiring sub-zero operation must use TC4467EJD or alternative gate drivers rated for extended low-temperature ranges.

Q: What is the difference between 14-CERDIP and 14-PDIP packaging?

A: Both are 14-pin through-hole packages with 0.300" (7.62mm) pitch. CERDIP (Ceramic Dual In-line Package) uses ceramic substrate construction, while PDIP (Plastic Dual In-line Package) uses plastic substrate construction. Pin configurations and mechanical dimensions are equivalent, allowing direct PCB layout compatibility.

Q: Why is TC4467EJD classified as obsolete?

A: Microchip Technology has transitioned the TC4467EJD to obsolete status. The TC4467CPD remains in active production and provides identical electrical functionality, making it the recommended replacement for new designs and ongoing production support.

Q: Are there any compliance or certification differences between these parts?

A: Both TC4467EJD and TC4467CPD maintain ROHS3 compliance, REACH unaffected status, and MSL rating of 1 (Unlimited). Compliance certifications are equivalent across both devices.

Q: What is the inventory status for these parts?

A: TC4467EJD has 739 pieces available as new original stock. TC4467CPD has 2700 pieces available as new original stock in tube packaging. The higher inventory level for TC4467CPD reflects its active product status.
