Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PI3A3899ZTEX is determined by strict equivalence across the following critical parameters:

• Switch circuit configuration (DPDT)
• Number of circuits (2)
• Multiplexer/demultiplexer circuit topology (2:2)
• On-state resistance maximum rating (2.4Ohm)
• Channel-to-channel matching tolerance (200mOhm)
• Supply voltage range (1.65V ~ 4.3V)
• Operating temperature range (-40°C ~ 85°C)
• Package type (16-UQFN)
• Surface mount mounting type
• RoHS3 compliance

The PI3A3899ZTAEX qualifies as a direct substitute based on full parameter equivalence across all critical electrical and mechanical specifications. The primary distinction is product status: PI3A3899ZTAEX is active, whereas PI3A3899ZTEX is obsolete.

Parameter Comparison

Engineering Selection Recommendations

The PI3A3899ZTAEX is the direct substitute for the obsolete PI3A3899ZTEX. Both parts are manufactured by Diodes Incorporated and maintain identical electrical specifications across all critical parameters including switch configuration, impedance characteristics, bandwidth, and operating conditions.

Selection of PI3A3899ZTAEX is supported by:

• Active product status ensuring ongoing availability and manufacturing support
• ROHS3 compliance matching the original part
• Identical electrical performance across all specified parameters
• MSL 1 rating providing unlimited shelf life
• Availability in Tape & Reel packaging format suitable for production environments

The 16-UQFN package dimensions differ slightly (1.8x2.6 versus 2.6x1.8), representing a rotation of the same package footprint. PCB layout compatibility is maintained for standard surface mount assembly processes.

Frequently Asked Questions (FAQ)

Q: Can PI3A3899ZTAEX be used as a direct replacement for PI3A3899ZTEX?

A: Yes. Both parts are electrically and mechanically equivalent across all critical parameters. The primary difference is product status: PI3A3899ZTAEX is active while PI3A3899ZTEX is obsolete.

Q: Are there differences in the package dimensions?

A: The package type is 16-UQFN for both parts. The dimension notation differs (2.6x1.8 versus 1.8x2.6), representing the same footprint in different orientations. Standard PCB assembly processes accommodate this variation.

Q: What is the significance of the Tape & Reel packaging for PI3A3899ZTAEX?

A: Tape & Reel (TR) packaging is the standard format for high-volume production environments, enabling automated pick-and-place assembly. This format is compatible with standard surface mount assembly equipment.

Q: Are both parts RoHS compliant?

A: Yes. Both PI3A3899ZTEX and PI3A3899ZTAEX are ROHS3 compliant and REACH unaffected, meeting environmental and regulatory requirements for electronic component manufacturing and use.

Q: What is the MSL rating and why does it matter?

A: Both parts carry MSL 1 (Unlimited) rating, indicating unlimited shelf life without moisture absorption concerns. This simplifies inventory management and storage requirements.

Q: Are the electrical performance characteristics identical?

A: Yes. On-state resistance, channel matching, bandwidth, charge injection, and all other specified electrical parameters are identical between the two parts, ensuring equivalent circuit performance.
