PI3B16233AEX Equivalent & Substitute Parts

Part Overview

The PI3B16233AEX is an 8 x 1:2 Multiplexer/Demultiplexer logic IC manufactured by Diodes Incorporated in a 56-TSSOP surface mount package. This component is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing design support and production continuity. The part operates across a single supply voltage range of 3V to 3.6V with an operating temperature range of -40°C to 85°C. Substitute parts must maintain compatibility with these electrical specifications and the 56-TFSOP (0.240", 6.10mm Width) package footprint.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the PI3B16233AEX are qualified based on the following critical parameters:

• Package Compatibility: Both substitute parts use the 56-TFSOP (0.240", 6.10mm Width) package, ensuring PCB footprint and mounting compatibility
• Voltage Supply Source: Single supply operation maintained across all alternatives
• Operating Temperature Range: All parts support -40°C to 85°C operation
• Surface Mount Technology: Consistent mounting methodology
• RoHS3 Compliance: Environmental regulatory alignment
• REACH Unaffected Status: Regulatory compliance maintained

The substitute parts are manufactured by Renesas Electronics Corporation under the QS3VH series. While the circuit configuration differs (2 x 16:8 versus 8 x 1:2), both configurations provide equivalent multiplexer/demultiplexer functionality within the same package envelope and electrical operating parameters. The QS3VH16233 base product number represents the functionally equivalent logic family.

Parameter Comparison

Engineering Selection Recommendations

Product Status Consideration: The PI3B16233AEX is classified as obsolete. Both QS3VH16233PAG8 and QS3VH16233PAG are active products from Renesas Electronics Corporation, ensuring long-term availability and manufacturing support.

Compliance Alignment: All three parts maintain ROHS3 compliance and REACH unaffected status, satisfying current environmental and regulatory requirements for electronic component procurement.

Moisture Sensitivity: The substitute parts feature MSL 1 (Unlimited) rating compared to the main part's MSL 2A (4 Weeks), providing superior moisture handling characteristics and reduced storage constraints during manufacturing and assembly operations.

Packaging Availability: QS3VH16233PAG8 is supplied in Cut Tape (CT) & Digi-Reel® format, while QS3VH16233PAG is supplied in Tube format. Selection between these variants depends on production volume requirements and assembly line equipment compatibility.

Voltage Supply Range: The substitute parts support a wider voltage supply range (2.3V ~ 3.6V) compared to the main part (3V ~ 3.6V), providing additional design flexibility for applications operating at lower supply voltages while maintaining full compatibility with the original 3V ~ 3.6V specification.

Frequently Asked Questions (FAQ)

Q: Can QS3VH16233PAG8 and QS3VH16233PAG be used interchangeably?

A: Both parts are functionally equivalent with identical electrical specifications and package footprints. The primary difference is packaging format: QS3VH16233PAG8 uses Cut Tape (CT) & Digi-Reel® while QS3VH16233PAG uses Tube packaging. Selection depends on production volume and assembly equipment requirements.

Q: What is the impact of the different circuit configurations (8 x 1:2 versus 2 x 16:8)?

A: Both configurations provide equivalent multiplexer/demultiplexer functionality within the same 56-TSSOP package. The circuit configuration difference reflects internal architecture optimization by the respective manufacturers while maintaining functional equivalence for the intended application.

Q: Are there any thermal or electrical performance differences between the main part and substitutes?

A: All parts share identical operating temperature ranges (-40°C to 85°C) and single supply voltage operation. The substitute parts support a wider supply voltage range (2.3V ~ 3.6V versus 3V ~ 3.6V), providing additional operational flexibility without performance degradation.

Q: How does the improved MSL rating of substitute parts affect production planning?

A: The MSL 1 (Unlimited) rating of substitute parts eliminates the 4-week storage constraint associated with the main part's MSL 2A rating. This reduces inventory management complexity and extends shelf life, improving supply chain efficiency.

Q: Is the 56-TFSOP package footprint identical across all three parts?

A: Yes. All parts use the 56-TFSOP (0.240", 6.10mm Width) package with identical PCB footprint dimensions, enabling direct substitution without circuit board redesign.
