CBTL04GP043EXJ Equivalent & Substitute Parts

Part Overview

The CBTL04GP043EXJ is a dual DPDT (Double Pole Double Throw) logic switch IC manufactured by NXP USA Inc., housed in a 28-XFBGA (2x4) package. This component functions as a 15Ohm switch matrix suitable for signal routing and multiplexing applications. The part is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing design support and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the CBTL04GP043EXJ is determined by the following critical parameters:

• Switch Configuration: DPDT topology with dual channels and 15Ohm on-state resistance
• Package Compatibility: 28-XFBGA (2x4) form factor for surface mount PCB integration
• Operating Temperature Range: -20°C ~ 85°C minimum requirement
• Supply Voltage: Compatibility with the original supply voltage specifications
• Compliance Standards: RoHS and REACH certification status for regulatory alignment

The identified substitute, CBTL08GP053EVY, represents a functional alternative from NXP Semiconductors within the same logic switch family. However, this substitute operates in a different application domain (USB Type-C switching) and exhibits different electrical characteristics, requiring careful evaluation of circuit-level compatibility before implementation.

Parameter Comparison

Engineering Selection Recommendations

Both the CBTL04GP043EXJ and CBTL08GP053EVY are classified as obsolete products. Selection between these components must account for the following compliance and regulatory factors:

RoHS Compliance: The CBTL04GP043EXJ maintains RoHS3 compliance, while the CBTL08GP053EVY is non-compliant. For applications subject to RoHS directives, the original part number remains the preferred choice if inventory is available.

REACH Status: The CBTL04GP043EXJ carries REACH Unaffected status, providing regulatory clarity. The CBTL08GP053EVY lists REACH status as Vendor Undefined, introducing uncertainty for supply chain compliance documentation.

Package Footprint: The substitute requires a larger 40-VFBGA (4.75x3.25) package compared to the original 28-XFBGA (2x4), necessitating PCB layout redesign and potential board space reallocation.

Operating Temperature: The CBTL08GP053EVY extends the lower operating temperature to -40°C, exceeding the original -20°C specification. This provides broader environmental coverage for applications requiring extended temperature ranges.

Electrical Characteristics: The substitute offers lower on-state resistance (10Ohm vs. 15Ohm), which may provide improved signal integrity in high-frequency applications but requires circuit validation to confirm compatibility.

Frequently Asked Questions (FAQ)

Q: Can the CBTL08GP053EVY directly replace the CBTL04GP043EXJ without PCB modifications?

A: No. The substitute uses a different package (40-VFBGA vs. 28-XFBGA), requiring PCB footprint redesign and layout changes. Pin assignments and electrical characteristics also differ, necessitating schematic review.

Q: What is the primary functional difference between these two parts?

A: The CBTL04GP043EXJ is a general-purpose dual DPDT logic switch, while the CBTL08GP053EVY is optimized for USB Type-C high-speed signal routing. Application context determines suitability.

Q: Does the CBTL08GP053EVY meet RoHS requirements?

A: No. The CBTL08GP053EVY is RoHS non-compliant. For applications requiring RoHS certification, alternative parts or the original CBTL04GP043EXJ (if available) must be evaluated.

Q: What is the impact of the lower on-state resistance in the substitute?

A: The 10Ohm resistance in the CBTL08GP053EVY versus 15Ohm in the original may reduce signal attenuation and improve bandwidth performance. However, circuit-level validation is required to confirm compatibility with existing impedance matching and signal integrity requirements.

Q: Are both parts still in production?

A: Both components are classified as obsolete. Availability is limited to existing inventory. Long-term design strategies should consider transitioning to current-generation NXP switch ICs with similar functionality.
