PI5A393AW Equivalent & Substitute Parts

Part Overview

The PI5A393AW is a 4-circuit IC switch manufactured by Diodes Incorporated, featuring SPST NO/NC configuration with 18Ohm on-state resistance in a 16-SOIC package. This component is classified as obsolete, making equivalent substitutes necessary for new designs and ongoing production requirements. The part operates across a 2V to 6V supply range with 200MHz bandwidth and is suitable for signal switching and multiplexing applications in interface circuits.

Substitute Part Grouping Explanation

Substitution for the PI5A393AW is based on the following critical parameters that must remain compatible:

Switch Configuration: SPST NO/NC topology with 4 independent circuits in 1:1 multiplexer/demultiplexer arrangement
Package Type: 16-SOIC surface mount package with identical 0.154" (3.90mm) width
Operating Temperature Range: -40°C to 85°C (TA)
Bandwidth Performance: 200MHz minimum -3dB bandwidth
Supply Voltage Compatibility: Single supply operation within overlapping voltage ranges

The ADG713BRZ series from Analog Devices Inc. meets all functional and mechanical substitution criteria. These parts maintain identical circuit topology, package footprint, and operating temperature specifications. The ADG713BRZ variants differ only in packaging format (Tube vs. Tape & Reel) and represent active, production-status alternatives to the obsolete PI5A393AW.

Engineering Selection Recommendations

The ADG713BRZ series represents the primary substitution path for the obsolete PI5A393AW. All three variants (ADG713BRZ, ADG713BRZ-REEL, ADG713BRZ-REEL7) are functionally equivalent and maintain active product status with ROHS3 compliance.

Selection between variants depends on procurement and assembly requirements:

ADG713BRZ: Tube packaging, suitable for lower-volume applications and manual assembly processes
ADG713BRZ-REEL: Tape & Reel (TR) packaging, optimized for automated pick-and-place assembly
ADG713BRZ-REEL7: Standard reel packaging format with highest available inventory (26,955 pcs), recommended for high-volume production

The ADG713BRZ series offers performance improvements over the PI5A393AW, including reduced on-state resistance (4Ohm vs. 18Ohm), lower leakage current (100pA vs. 30nA), and improved crosstalk performance (-90dB vs. -72dB). Supply voltage range compatibility spans the PI5A393AW operating window (1.8V to 5.5V encompasses 2V to 6V operation).

Frequently Asked Questions (FAQ)

Q: Can ADG713BRZ variants be used as direct pin-for-pin replacements for PI5A393AW?

A: Yes. All ADG713BRZ variants maintain identical 16-SOIC package footprint and pinout configuration. No PCB layout modifications are required for substitution.

Q: What are the differences between ADG713BRZ, ADG713BRZ-REEL, and ADG713BRZ-REEL7?

A: The three variants are electrically identical. Differences exist only in packaging format: ADG713BRZ uses Tube packaging, ADG713BRZ-REEL uses Tape & Reel format, and ADG713BRZ-REEL7 uses standard reel packaging. Selection depends on assembly process requirements and volume needs.

Q: Does the lower on-state resistance of ADG713BRZ (4Ohm vs. 18Ohm) affect circuit compatibility?

A: Lower on-state resistance is a performance improvement that reduces signal attenuation and power dissipation. This change is compatible with existing circuit designs and does not introduce incompatibility.

Q: Are there supply voltage compatibility concerns when substituting PI5A393AW with ADG713BRZ?

A: The ADG713BRZ supply range (1.8V to 5.5V) overlaps with the PI5A393AW range (2V to 6V) across the 2V to 5.5V window. Applications operating above 5.5V require design review.

Q: What is the impact of improved crosstalk performance in ADG713BRZ?

A: The ADG713BRZ crosstalk specification (-90dB @ 10MHz) represents improved isolation compared to PI5A393AW (-72dB @ 30MHz). This enhancement reduces signal coupling between channels and is beneficial for signal integrity.

Q: Is RoHS compliance a consideration for this substitution?

A: The PI5A393AW is RoHS non-compliant, while all ADG713BRZ variants are ROHS3 compliant. Applications subject to RoHS requirements must use ADG713BRZ series substitutes.
