Engineering Selection Recommendations
For Direct Replacement (Recommended for Pin-Compatible Designs):
The PCA9519PW,118 from NXP USA Inc. is the direct equivalent substitute. It maintains identical electrical specifications, package footprint, and pin configuration while offering active product status. Both parts are ROHS3 compliant with unlimited moisture sensitivity rating (MSL 1), ensuring compatibility with standard manufacturing processes.
For Enhanced Performance Applications:
The Renesas 89HP0604 series (89HP0604QBZBNRG, 89HP0604QBZBNRG8, 89HP0604QBZBNRGI, 89HP0604QBZBNRGI8, 89HP0604QZBNRG, 89HP0604QZBNRG8, 89HP0604QZBNRGI, 89HP0604QZBNRGI8) provides higher data rate capability at 6.25Gbps. These parts are suitable for applications requiring enhanced bandwidth while maintaining 4-channel I2C buffer functionality. The 36-VFQFPN package requires PCB layout redesign. All variants are ROHS3 compliant and active products, though MSL rating is 3 (168 Hours), requiring controlled storage conditions.
Frequently Asked Questions (FAQ)
Q: Can PCA9519PW,118 be used as a direct drop-in replacement for PCA9519PW,112?
A: Yes. Both parts share identical electrical specifications, pin configuration, package dimensions (20-TSSOP), and functional characteristics. The primary difference is packaging format (individual vs. tape & reel) and product status (obsolete vs. active).
Q: What is the key difference between NXP and Renesas substitute options?
A: The NXP PCA9519PW,118 maintains the original 400kHz data rate and 20-TSSOP package, requiring no design changes. The Renesas 89HP0604 series offers 6.25Gbps data rate capability but requires a different package footprint (36-VFQFPN), necessitating PCB redesign.
Q: Are all Renesas 89HP0604 variants electrically equivalent?
A: Yes. All eight variants (QBZBNRG, QBZBNRG8, QBZBNRGI, QBZBNRGI8, QZBNRG, QZBNRG8, QZBNRGI, QZBNRGI8) share identical electrical specifications and functional characteristics. Variant designations reflect internal configuration or temperature grade options.
Q: What is the MSL rating difference, and does it affect component selection?
A: PCA9519PW,112 and PCA9519PW,118 have MSL 1 (unlimited shelf life). Renesas 89HP0604 series has MSL 3 (168-hour limit after moisture exposure). MSL 3 requires controlled storage and baking procedures before reflow soldering in humid environments.
Q: Can the Renesas parts be used in existing PCB designs without modification?
A: No. The 36-VFQFPN package is incompatible with the 20-TSSOP footprint. PCB layout redesign is required, including trace routing and via placement adjustments.
Q: Are all substitute parts ROHS3 compliant?
A: Yes. PCA9519PW,112, PCA9519PW,118, and all Renesas 89HP0604 variants are ROHS3 compliant, meeting environmental and hazardous substance restrictions.
