PCA9552PW,118 Equivalent & Substitute Parts

Part Overview

The PCA9552PW,118 is a 16-output LED driver IC manufactured by NXP USA Inc., designed for power switch applications with I2C-based dimming control. This device operates across a 2.3V to 5.5V supply range and delivers 25mA per output channel at 400kHz frequency. The component is housed in a 24-TSSOP surface mount package and maintains Active product status with full ROHS3 compliance. Substitute parts are identified when equivalent electrical specifications, package compatibility, and operational parameters align with the original design requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the PCA9552PW,118 are qualified based on the following critical parameters:

• 16 output channels for LED driving applications
• Supply voltage range of 2.3V to 5.5V
• 25mA maximum output current per channel
• I2C protocol for dimming control
• 400kHz operating frequency
• 24-TSSOP surface mount package with identical physical dimensions
• Operating temperature range of -40°C to 85°C
• Active product status with current manufacturing availability
• ROHS3 compliance and equivalent moisture sensitivity level

The CAT9532YI-T2 qualifies as a substitute based on matching all electrical specifications, package geometry, and environmental ratings. The primary functional difference is the internal topology classification (Linear versus Power Switch), which does not affect substitution eligibility when output current and voltage specifications remain identical.

Parameter Comparison

Engineering Selection Recommendations

Both the PCA9552PW,118 and CAT9532YI-T2 maintain Active product status with confirmed manufacturing availability and full regulatory compliance. Selection between these components should be based on:

• Procurement lead time and inventory availability from authorized distributors
• Manufacturer qualification requirements specific to your organization
• Supply chain continuity and long-term availability forecasts
• Cost considerations and volume pricing structures
• Existing design validation history with either manufacturer's LED driver portfolio

Both devices satisfy identical electrical, thermal, and mechanical requirements for 16-channel LED driving applications operating within the 2.3V to 5.5V supply envelope. Package compatibility is confirmed through matching 24-TSSOP geometry and surface mount specifications.

Frequently Asked Questions (FAQ)

Q: Can the CAT9532YI-T2 be used as a direct replacement for the PCA9552PW,118 on existing PCBs?

A: Yes. Both components share identical 24-TSSOP package dimensions (0.173" × 4.40mm width) and pinout compatibility for surface mount assembly. No PCB layout modifications are required.

Q: What is the difference between Power Switch and Linear topology classifications?

A: The topology classification reflects internal circuit architecture. Both configurations deliver identical 25mA output current per channel and operate across the same 2.3V to 5.5V supply range. The functional output specifications remain equivalent for LED driving applications.

Q: Are the I2C control protocols identical between these parts?

A: Both devices implement I2C-based dimming control at 400kHz frequency. I2C protocol compatibility is maintained across both components.

Q: Do both parts meet the same environmental and compliance standards?

A: Yes. Both the PCA9552PW,118 and CAT9532YI-T2 are ROHS3 compliant, REACH unaffected, and rated for -40°C to 85°C operating temperature. Moisture sensitivity level is 1 (Unlimited) for both devices.

Q: What packaging formats are available for these LED drivers?

A: The PCA9552PW,118 is supplied in Cut Tape (CT) and Digi-Reel format. The CAT9532YI-T2 is supplied in Tape & Reel (TR) format. Both formats are standard for surface mount component distribution.

Q: Are there any output current limitations per channel?

A: Both devices are rated for 25mA maximum output current per channel. Design calculations must account for this specification when determining LED load requirements.
