TSC426C/D Equivalent & Substitute Parts

Part Overview

The TSC426C/D is a low-side gate driver IC with inverting die configuration, manufactured by Analog Devices Inc./Maxim Integrated. This component is classified as a Power Management (PMIC) device designed to drive N-Channel and P-Channel MOSFETs in low-side configurations with independent dual-channel capability. The TSC426C/D is currently listed as obsolete, making identification of active equivalent parts essential for ongoing design support and procurement.

Substitute Part Grouping Explanation

Substitution of the TSC426C/D is determined by strict equivalence across the following critical parameters:

• Driven Configuration: Low-Side
• Number of Drivers: 2 (dual-channel independent)
• Gate Type: N-Channel, P-Channel MOSFET support
• Voltage - Supply: 4.5V ~ 18V
• Logic Voltage - VIL, VIH: 0.8V, 2.4V
• Current - Peak Output (Source, Sink): 1.5A, 1.5A
• Input Type: Inverting
• Rise / Fall Time (Typ): 25ns, 25ns
• Operating Temperature: 0°C ~ 70°C
• Base Product Number: TSC426

The TSC426CPA+ maintains identical electrical specifications and functional characteristics while differing only in packaging format and product status. The TSC426CPA+ is an active product available in 8-DIP through-hole packaging, whereas the TSC426C/D is an obsolete die form.

Parameter Comparison

Engineering Selection Recommendations

The TSC426CPA+ is the direct functional equivalent to the obsolete TSC426C/D. Both components share identical electrical specifications, logic thresholds, output current ratings, and timing characteristics. The primary distinction is packaging: the TSC426C/D is supplied as a die form for hybrid integration, while the TSC426CPA+ is packaged in 8-DIP through-hole format for discrete circuit applications.

Selection of the TSC426CPA+ is appropriate for applications requiring an active, supported component with equivalent gate driver functionality. Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements. The through-hole package of the TSC426CPA+ requires PCB layout modifications compared to the die form, but electrical performance remains identical.

Frequently Asked Questions (FAQ)

Q: Can the TSC426CPA+ directly replace the TSC426C/D in all applications?

A: Electrical substitution is complete. The TSC426CPA+ provides identical gate driver functionality, supply voltage range, logic thresholds, output current, and timing specifications. PCB layout and assembly process changes are required due to packaging differences (die versus 8-DIP through-hole).

Q: What are the key differences between these parts?

A: The TSC426C/D is a die form intended for hybrid circuit assembly, while the TSC426CPA+ is a packaged 8-DIP component for discrete PCB mounting. All electrical parameters are identical. The TSC426CPA+ is an active product; the TSC426C/D is obsolete.

Q: Are there compliance or certification differences?

A: Both parts are ROHS3 compliant and REACH unaffected. Moisture sensitivity level is identical at MSL 1 (Unlimited). No compliance differences exist between the two parts.

Q: What mounting considerations apply to the TSC426CPA+?

A: The TSC426CPA+ uses through-hole mounting in an 8-DIP package with 0.300" (7.62mm) pin spacing. This requires standard DIP socket or PCB through-hole assembly, differing from the die form which requires hybrid circuit integration techniques.

Q: Is the TSC426CPA+ currently available?

A: Yes, the TSC426CPA+ is an active product with current manufacturing support and availability. The TSC426C/D is obsolete and no longer manufactured.
