PCA9632DP2,118 Equivalent & Substitute Parts

Part Overview

The PCA9632DP2,118 is a 4-output LED driver IC with I2C dimming control, designed for backlight applications. Manufactured by NXP USA Inc., this power switch integrates internal switching capability with a 25mA per-channel output capacity and operates across a 2.3V to 5.5V supply range. The device is classified as obsolete, making identification of compatible substitute parts essential for ongoing production and maintenance applications. The PCA9632DP2Z represents the active production equivalent, offering identical electrical and mechanical specifications with current availability.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the PCA9632DP2,118 is determined by strict equivalence across the following critical parameters:

• Electrical Specifications: Supply voltage range (2.3V–5.5V), output voltage (5.5V), per-channel current capacity (25mA), and frequency range (100kHz–1MHz) must remain identical
• Functional Interface: I2C dimming control protocol must be maintained
• Output Configuration: 4-output architecture is non-negotiable
• Thermal Operating Range: -40°C to 85°C ambient temperature specification
• Package Compatibility: 10-TFSOP/10-MSOP form factor with 0.118" (3.00mm) width ensures PCB layout compatibility
• Compliance Standards: RoHS3 compliance and MSL Level 1 rating must be preserved

The PCA9632DP2Z meets all substitution criteria as a direct equivalent from the same manufacturer, differing only in product status (active vs. obsolete) and packaging format (Cut Tape & Digi-Reel vs. standard).

Parameter Comparison

Engineering Selection Recommendations

The PCA9632DP2Z is the direct active production equivalent of the obsolete PCA9632DP2,118. Both parts maintain identical electrical performance, thermal ratings, and compliance certifications (ROHS3, REACH Unaffected, EAR99 classification). The transition from the obsolete to active part number reflects standard product lifecycle management by NXP USA Inc., with no functional or performance degradation. For new designs or production continuity, the PCA9632DP2Z is the appropriate selection. Both parts are suitable for backlight LED driver applications requiring 4-channel I2C-controlled dimming within the specified voltage and current parameters.

Frequently Asked Questions (FAQ)

Q: Can the PCA9632DP2Z directly replace the PCA9632DP2,118 in existing designs?

A: Yes. Both parts are electrically and mechanically identical. The PCA9632DP2Z is the active production equivalent and requires no circuit modifications or PCB layout changes.

Q: What is the difference between these two part numbers?

A: The primary difference is product status: PCA9632DP2,118 is obsolete, while PCA9632DP2Z is active. Packaging format differs (standard vs. Cut Tape & Digi-Reel), but electrical specifications, pin configuration, and performance are identical.

Q: Are there any compliance or certification differences?

A: No. Both parts carry identical RoHS3 compliance, MSL Level 1 rating, REACH Unaffected status, and EAR99 ECCN classification.

Q: Is the 10-TFSOP/10-MSOP package footprint identical between both parts?

A: Yes. Both parts use the same 10-TFSOP/10-MSOP package with 0.118" (3.00mm) width, ensuring full PCB compatibility without layout modifications.

Q: What applications are these parts suitable for?

A: Both parts are designed for backlight LED driver applications requiring 4-channel I2C dimming control across the 2.3V–5.5V supply range with 25mA per-channel output capacity.
