P0084UARP Equivalent & Substitute Parts

Part Overview

The P0084UARP is a SIDACtor® Transient Voltage Suppressor (TVS) thyristor designed for overvoltage protection in electronic circuits. This component features 6V and 12V off-state voltage ratings with a 150 A peak pulse current capability in a 6-SMD Gull Wing surface mount package. The P0084UARP is classified as obsolete, making identification of active equivalent parts essential for ongoing design support and procurement.

• Voltage - On State: 4 V
• Current - Peak Pulse (8/20µs): 150 A
• Current - Peak Pulse (10/1000µs): 45 A
• Number of Elements: 4
• Capacitance: 90pF, 155pF

Mechanical Parameters (Must Match):

• Package / Case: 6-SMD, Gull Wing
• Mounting Type: Surface Mount
• Supplier Device Package: Modified MS-013

Allowed Variations:

• Packaging format (Tape & Reel, Tube, or Bulk)
• Current - Hold (Ih) values
• Product status (Active substitutes for Obsolete)
• RoHS and REACH compliance status

Parameter Comparison

Engineering Selection Recommendations

Both P0084UALRP and P0084UALTP are direct electrical and mechanical equivalents to the obsolete P0084UARP. Selection between these active alternatives is based on procurement and assembly requirements:

P0084UALRP (Tape & Reel): Suitable for high-volume automated assembly operations. ROHS3 compliant with REACH Unaffected status. Recommended for production environments with tape-fed pick-and-place equipment.

P0084UALTP (Tube): Suitable for lower-volume applications and manual assembly processes. ROHS3 compliant with REACH Unaffected status. Recommended for prototype development and small-batch manufacturing.

Both substitute parts feature improved hold current specifications (50 mA versus 150 mA) and current regulatory compliance compared to the obsolete main part.

Frequently Asked Questions (FAQ)

Q: Can P0084UALRP and P0084UALTP be used interchangeably with P0084UARP?

A: Yes. Both parts are electrically and mechanically equivalent. They differ only in packaging format (Tape & Reel versus Tube) and product status (Active versus Obsolete). Selection depends on assembly method and procurement volume.

Q: What is the difference between the hold current values?

A: The P0084UARP specifies 150 mA hold current, while P0084UALRP and P0084UALTP specify 50 mA. This parameter variation is within the allowed substitution criteria and does not affect circuit compatibility for standard TVS thyristor applications.

Q: Are the substitute parts RoHS compliant?

A: Yes. Both P0084UALRP and P0084UALTP are ROHS3 compliant, whereas the P0084UARP is RoHS non-compliant. This makes the substitute parts suitable for applications requiring regulatory compliance.

Q: Does packaging format affect electrical performance?

A: No. Tape & Reel and Tube packaging formats contain identical components. Packaging selection is based on assembly equipment compatibility and procurement logistics, not electrical characteristics.

Q: Why is the P0084UARP classified as obsolete?

A: The P0084UARP has been superseded by active alternatives with improved compliance status. P0084UALRP and P0084UALTP provide equivalent electrical and mechanical performance with current regulatory certifications.
