PS9552L2-AX Equivalent & Substitute Parts

Part Overview

The PS9552L2-AX is a 2.5A gate driver optical coupling device manufactured by CEL, providing 5000Vrms isolation in a single-channel configuration. This component is classified as obsolete, which necessitates the identification of suitable substitute parts for ongoing applications and new designs. Active alternative components with equivalent or superior electrical characteristics are available from Vishay Semiconductor Opto Division.

Substitute Part Grouping Explanation

Substitution for the PS9552L2-AX is determined by the following critical parameters:

Electrical Compatibility Requirements:

Isolation voltage equal to or greater than 5000Vrms
Single-channel gate driver configuration
Peak output current rating of 2.5A minimum
Optical coupling technology
Output supply voltage range compatibility (15V ~ 30V or wider)

Mechanical Compatibility Requirements:

8-SMD surface mount package with Gull Wing lead configuration

The VO3120-X007T and VO3120-X019T variants from Vishay meet all electrical and mechanical substitution criteria. These parts are functionally equivalent, with enhanced specifications in isolation voltage (5300Vrms), faster propagation delay (400ns vs. 500ns), and lower pulse width distortion (200ns vs. 300ns). Both variants are active products with ROHS3 compliance, differing only in packaging format (Cut Tape vs. Tape & Reel).

Engineering Selection Recommendations

VO3120-X007T (Cut Tape & Digi-Reel®) is suitable for applications requiring medium to high-volume component distribution. This packaging format accommodates automated assembly processes with standard tape and reel handling. The part is actively manufactured and complies with ROHS3 standards, providing long-term supply assurance.

VO3120-X019T (Tape & Reel) is designated for high-volume production environments with integrated tape and reel logistics. This variant is actively produced with ROHS3 compliance and includes VDE certification in addition to cUR and UR approvals, offering extended compliance scope.

Both substitute parts exceed the electrical specifications of the obsolete PS9552L2-AX, with superior isolation voltage, faster propagation delays, and improved pulse width distortion characteristics. The extended operating temperature range (-40°C ~ 110°C) of the Vishay variants provides increased margin for high-temperature applications compared to the PS9552L2-AX (-40°C ~ 100°C).

Frequently Asked Questions (FAQ)

Q: Can VO3120-X007T and VO3120-X019T be used interchangeably with PS9552L2-AX?

A: Both Vishay parts are functionally equivalent to PS9552L2-AX in critical electrical parameters: isolation voltage (5300Vrms exceeds 5000Vrms), peak output current (2.5A), and single-channel optical coupling configuration. They share identical package geometry (8-SMD Gull Wing). The primary distinction lies in packaging format and compliance certifications.

Q: What is the difference between VO3120-X007T and VO3120-X019T?

A: VO3120-X007T is supplied in Cut Tape & Digi-Reel® format, while VO3120-X019T is supplied in Tape & Reel format. Electrical specifications are identical. VO3120-X019T includes additional VDE certification. Selection depends on procurement and assembly infrastructure requirements.

Q: Are there temperature considerations when substituting with Vishay parts?

A: The Vishay substitute parts operate over -40°C ~ 110°C, extending 10°C above the PS9552L2-AX operating range (-40°C ~ 100°C). This extended range does not create compatibility issues and provides additional thermal margin for applications operating near upper temperature limits.

Q: What compliance advantages do the Vishay substitutes offer?

A: Both VO3120-X007T and VO3120-X019T are ROHS3 compliant and actively manufactured. The obsolete PS9552L2-AX status eliminates future procurement options. VO3120-X019T includes VDE certification in addition to cUR and UR approvals, providing broader regulatory coverage for European markets.

Q: Does the improved propagation delay of Vishay parts affect circuit design?

A: The Vishay substitutes provide faster propagation delays (400ns maximum vs. 500ns for PS9552L2-AX) and lower pulse width distortion (200ns vs. 300ns). These improvements do not require design modifications and enhance overall signal fidelity in gate driver applications.
