PI5A392AQEX Equivalent & Substitute Parts

Part Overview

The PI5A392AQEX is a 4-circuit SPST-NO IC switch manufactured by Diodes Incorporated, designed for high-speed signal switching applications. This part operates across a 2V to 6V single supply range with an 18Ohm maximum on-state resistance and delivers 200MHz bandwidth performance. The device is actively produced and ROHS3 compliant, making it suitable for modern electronic designs requiring reliable switching functionality.

Substitute parts become necessary when the PI5A392AQEX reaches end-of-life status, inventory constraints occur, or design requirements favor alternative electrical characteristics such as lower on-state resistance or improved leakage specifications.

Engineering Selection Recommendations

All listed substitute parts maintain active product status and ROHS3 compliance, ensuring long-term availability and regulatory alignment with the PI5A392AQEX.

ADG712BRUZ Series (Analog Devices Inc.): Available in three packaging configurations—tube (ADG712BRUZ), tape & reel (ADG712BRUZ-REEL), and cut tape with Digi-Reel (ADG712BRUZ-REEL7)—these parts deliver superior electrical performance with 4Ohm on-state resistance, faster switching times (11ns/6ns typical), and improved crosstalk isolation (-90dB @ 10MHz). The supply voltage range (1.8V ~ 5.5V) overlaps the PI5A392AQEX specification. Inventory availability ranges from 10,600 to 21,370 units across packaging options.

MAX4652EUE+ Series (Analog Devices Inc./Maxim Integrated): Available in tube (MAX4652EUE+) and cut tape with Digi-Reel (MAX4652EUE+T) packaging, these parts offer the lowest charge injection (2pC) and superior crosstalk performance (-100dB @ 1MHz). On-state resistance matches the ADG712 series at 4Ohm with tighter channel-to-channel matching (50mOhm). Supply voltage range is 1.8V ~ 5.5V. Inventory availability is 1,226 units (tube) and 3,800 units (cut tape).

Package transition from 16-SSOP to 16-TSSOP requires PCB layout verification due to the 0.5mm width increase (3.90mm to 4.40mm).

Frequently Asked Questions (FAQ)

Q: Can ADG712BRUZ parts directly replace PI5A392AQEX without PCB modifications?

A: Functional substitution is possible, but physical layout changes are required. The PI5A392AQEX uses 16-SSOP packaging (3.90mm width), while ADG712BRUZ parts use 16-TSSOP packaging (4.40mm width). PCB footprint adjustment is necessary. All electrical parameters remain compatible within the specified operating ranges.

Q: What is the primary electrical advantage of ADG712BRUZ over PI5A392AQEX?

A: The ADG712BRUZ reduces on-state resistance from 18Ohm to 4Ohm, resulting in lower power dissipation and reduced signal attenuation. Switching times are also faster (11ns/6ns typical versus 20ns/10ns maximum), and crosstalk isolation improves to -90dB @ 10MHz.

Q: Are MAX4652EUE+ parts suitable for high-frequency applications?

A: MAX4652EUE+ parts deliver the lowest charge injection (2pC) and highest crosstalk isolation (-100dB @ 1MHz) among the listed substitutes. However, bandwidth specification is not provided for this part. Applications requiring explicit bandwidth confirmation should reference the MAX4652 datasheet or contact the manufacturer.

Q: What packaging options are available for volume production?

A: ADG712BRUZ-REEL7 offers the highest inventory (21,370 units) in cut tape with Digi-Reel packaging, suitable for automated assembly. ADG712BRUZ-REEL provides 15,200 units in tape & reel format. For smaller quantities, ADG712BRUZ (tube, 10,600 units) and MAX4652EUE+T (cut tape, 3,800 units) are available.

Q: Do all substitute parts meet the same compliance standards as PI5A392AQEX?

A: Yes. All listed substitutes are ROHS3 compliant, REACH unaffected, and carry MSL rating of 1 (Unlimited), matching the PI5A392AQEX compliance profile. All parts are classified under ECCN EAR99 and HTSUS 8542.39.0001.

Q: What is the voltage supply compatibility range for substitutes?

A: Substitute parts operate at 1.8V ~ 5.5V, which overlaps the PI5A392AQEX range of 2V ~ 6V. Applications operating below 1.8V or above 5.5V require the original PI5A392AQEX. Applications within 2V ~ 5.5V are compatible with all substitutes.
