UCD7100PWPRG4 Equivalent & Substitute Parts

Part Overview

The UCD7100PWPRG4 is a low-side gate driver IC manufactured by Texas Instruments, designed for driving N-channel MOSFETs in power management applications. This device operates as a non-inverting single-channel gate driver with a supply voltage range of 4.25V to 15V and peak output current capability of 4A source and sink. The UCD7100PWPRG4 is currently discontinued at DiGi Electronics, making identification of equivalent substitute parts essential for ongoing design support and procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the UCD7100PWPRG4 is determined by strict equivalence across the following critical parameters:

• Driven Configuration: Low-Side
• Channel Type: Single
• Number of Drivers: 1
• Gate Type: N-Channel MOSFET
• Voltage - Supply: 4.25V ~ 15V
• Logic Voltage - VIL, VIH: 1.16V, 2.08V
• Current - Peak Output (Source, Sink): 4A, 4A
• Input Type: Non-Inverting
• Rise / Fall Time (Typ): 10ns, 10ns
• Operating Temperature: -40°C ~ 105°C (TJ)
• Package / Case: 14-PowerTSSOP (0.173", 4.40mm Width)

The UCD7100PWPR is identified as a direct substitute based on identical electrical specifications and mechanical compatibility. The primary distinction is packaging format: UCD7100PWPRG4 is supplied in tube packaging, while UCD7100PWPR is supplied in Tape & Reel (TR) format.

Parameter Comparison

Engineering Selection Recommendations

The UCD7100PWPR is the recommended substitute for the discontinued UCD7100PWPRG4. Both parts share identical electrical and mechanical specifications, including supply voltage range, output current capability, logic thresholds, and thermal operating range. Both maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment.

The UCD7100PWPR is currently in active production with substantial inventory availability (21,100 pcs), providing supply chain continuity. The packaging format difference (Tape & Reel versus tube) does not affect electrical performance or PCB assembly compatibility, as both formats contain the same die and package configuration.

Frequently Asked Questions (FAQ)

Q: Can UCD7100PWPR be used as a direct replacement for UCD7100PWPRG4?

A: Yes. Both parts are electrically and mechanically identical. The UCD7100PWPR operates across the same supply voltage range (4.25V to 15V), delivers identical peak output current (4A source and sink), maintains the same logic voltage thresholds, and is housed in the same 14-PowerTSSOP package. The only difference is packaging format (Tape & Reel versus tube).

Q: What is the significance of the packaging format difference?

A: Packaging format affects procurement and handling logistics but not electrical performance. Tape & Reel (TR) format is standard for high-volume automated assembly, while tube packaging is used for lower-volume or manual assembly applications. PCB assembly equipment can process both formats without modification.

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

A: No. Both UCD7100PWPRG4 and UCD7100PWPR maintain identical RoHS3 compliance, REACH unaffected status, and Moisture Sensitivity Level (MSL) rating of 2 (1 Year). Regulatory requirements are fully satisfied by either part.

Q: Why is UCD7100PWPRG4 discontinued?

A: The UCD7100PWPRG4 has been discontinued at DiGi Electronics. The UCD7100PWPR remains in active production and is the recommended path for ongoing procurement and design support.

Q: What are the critical parameters for substitution compatibility?

A: Substitution compatibility is determined by: driven configuration (low-side), channel type (single), gate type (N-channel MOSFET), supply voltage range (4.25V to 15V), peak output current (4A source and sink), input type (non-inverting), and package type (14-PowerTSSOP). All these parameters are identical between the two parts.
