Key Parameters

Substitute Part Grouping Explanation

Substitution of the PI5V331Q is determined by strict equivalence across the following critical parameters:

• Multiplexer configuration: 4:1 topology with 2-channel architecture
• Electrical performance: 10 Ohm maximum on-state resistance and 150 MHz minimum bandwidth
• Supply voltage: Single 5V supply requirement
• Switching characteristics: Bi-directional capability
• Physical form factor: 16-SSOP package with 3.90mm width
• Operating temperature range: -40°C to 85°C

Parts meeting all these criteria are considered direct functional equivalents. Variations in product status, packaging format, or compliance certifications do not affect electrical or mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

The PI5V331QE serves as the direct functional equivalent to the PI5V331Q. Both parts share identical electrical specifications, performance characteristics, and physical packaging requirements. The PI5V331QE is classified as Last Time Buy status, indicating continued availability with defined end-of-life parameters.

For applications requiring RoHS3 compliance, the PI5V331QE is the appropriate selection. The PI5V331Q, classified as RoHS non-compliant, may be suitable for legacy system maintenance where compliance requirements do not apply.

Both parts are manufactured by Diodes Incorporated under the PI5V331 base product number and maintain full electrical and mechanical interchangeability within the specified operating parameters.

Frequently Asked Questions (FAQ)

Q: Can PI5V331QE replace PI5V331Q in existing designs?

A: Yes. The PI5V331QE is electrically and mechanically equivalent to the PI5V331Q. All critical parameters—multiplexer configuration, on-state resistance, bandwidth, supply voltage, temperature range, and package form factor—are identical. Direct substitution is supported without circuit modification.

Q: What is the difference between PI5V331Q and PI5V331QE?

A: The primary differences are product status and compliance certification. The PI5V331Q is obsolete and RoHS non-compliant. The PI5V331QE is Last Time Buy status and ROHS3 compliant. Packaging format differs: PI5V331Q uses standard packaging while PI5V331QE is supplied in tube format. Electrical performance is identical.

Q: Are there inventory considerations when selecting between these parts?

A: The PI5V331Q has 758 pieces in stock (new original). The PI5V331QE has 2361 pieces in stock (new original). Given the Last Time Buy status of PI5V331QE, inventory availability should be confirmed for long-term production requirements.

Q: Does the 16-SSOP package remain consistent between both parts?

A: Yes. Both PI5V331Q and PI5V331QE use the 16-SSOP package with 0.154" width (3.90mm). PCB layout and footprint design require no modification for substitution.

Q: What compliance certifications apply to each part?

A: PI5V331Q: RoHS non-compliant, REACH Unaffected, ECCN EAR99. PI5V331QE: ROHS3 Compliant, REACH Unaffected, ECCN EAR99. Both parts share identical REACH and ECCN classifications.
