PI3B16233VE Equivalent & Substitute Parts

Part Overview

The PI3B16233VE is an 8 x 1:2 Multiplexer/Demultiplexer logic IC manufactured by Diodes Incorporated in a 56-SSOP surface mount package. This component is classified as obsolete, making equivalent and substitute parts necessary for new designs and ongoing production support. The part operates on single supply voltage (3V to 3.6V) across an industrial temperature range of -40°C to 85°C, with full RoHS3 compliance and unlimited moisture sensitivity rating.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the PI3B16233VE is determined by the following critical parameters: multiplexer/demultiplexer function type, circuit configuration capability, independent circuit count, surface mount packaging compatibility, operating temperature range, single supply voltage operation, and regulatory compliance status (RoHS3, REACH, MSL rating).

The substitute parts identified fall into two functional categories:

Category 1: Renesas QS3VH Series (QS3VH16233PAG and QS3VH16233PAG8) These parts maintain the 2 independent circuits requirement and support the same operating temperature range. They operate on a wider voltage supply range (2.3V ~ 3.6V), which encompasses the PI3B16233VE supply specification. Both are active products available in different packaging formats (Tube and Cut Tape/Digi-Reel). The 56-TFSOP package (0.240", 6.10mm Width) differs in width from the original but maintains 56-pin SSOP-class pinout compatibility.

Category 2: Texas Instruments SN74CBT16233DLR This part maintains the 56-BSSOP package footprint identical to the PI3B16233VE and supports 2 independent circuits. It operates on a different voltage supply range (4.75V ~ 5.25V), which does not overlap with the original 3V ~ 3.6V specification. This part is an active product with full compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

For voltage supply compatibility within the original 3V ~ 3.6V specification: The Renesas QS3VH16233PAG and QS3VH16233PAG8 are direct functional substitutes. Both parts are active products with full RoHS3 compliance and unlimited MSL rating. The QS3VH16233PAG8 offers higher inventory availability (6626 Pcs) compared to QS3VH16233PAG (1211 Pcs). Package width differs (6.10mm vs. 7.50mm original), requiring PCB layout verification for footprint compatibility.

For identical package footprint (56-BSSOP, 0.295" width): The Texas Instruments SN74CBT16233DLR maintains the original package dimensions but operates on 4.75V ~ 5.25V supply voltage, which is incompatible with the 3V ~ 3.6V specification of the PI3B16233VE. This part is suitable only for designs that can accommodate 5V supply operation.

For new designs: Select based on available supply voltage in your system. If 3V ~ 3.6V supply is required, use Renesas QS3VH series. If 5V supply is available and package footprint is critical, use Texas Instruments SN74CBT16233DLR. All substitute options are active products with full regulatory compliance.

Frequently Asked Questions (FAQ)

Q: Can QS3VH16233PAG and QS3VH16233PAG8 be used interchangeably with PI3B16233VE? A: Both Renesas parts are functionally equivalent for the 3V ~ 3.6V supply range. The primary difference is packaging format (Tube vs. Cut Tape/Digi-Reel). Electrical performance and pinout are identical. PCB layout must accommodate the 56-TFSOP package width of 6.10mm instead of the original 7.50mm.

Q: Why does SN74CBT16233DLR have a different voltage supply range? A: The Texas Instruments part is designed for 5V logic systems (4.75V ~ 5.25V). It is not a direct substitute for 3V ~ 3.6V applications but is included as an alternative for systems with 5V supply availability and identical package footprint requirements.

Q: Are all substitute parts RoHS3 compliant? A: Yes. All substitute parts listed (QS3VH16233PAG, QS3VH16233PAG8, and SN74CBT16233DLR) are ROHS3 compliant with unlimited MSL rating (1), matching the original PI3B16233VE compliance status.

Q: What is the impact of package width difference between PI3B16233VE and QS3VH series? A: The Renesas QS3VH parts use 56-TFSOP packaging (6.10mm width) versus the original 56-BSSOP (7.50mm width). Both are 56-pin surface mount packages with identical pin pitch. PCB layout and solder reflow profiles must be verified for the narrower package footprint.

Q: Which substitute part has the highest inventory availability? A: QS3VH16233PAG8 has 6626 Pcs in stock, compared to QS3VH16233PAG (1211 Pcs) and SN74CBT16233DLR (2961 Pcs).
