P2304UBRP Equivalent & Substitute Parts

Part Overview

The P2304UBRP is a SIDACtor® thyristor transient voltage suppressor manufactured by Littelfuse, designed for overvoltage protection in surface mount applications. This device features a 6-SMD gull wing package with dual voltage ratings (190V/380V off-state, 260V/520V breakover) and peak pulse current handling of 250 A at 8/20µs. The part is currently listed as obsolete, making identification of compatible substitutes essential for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the P2304UBRP is determined by strict equivalence across the following electrical and mechanical parameters:

• Voltage ratings (breakover and off-state): 260V/520V and 190V/380V respectively
• On-state voltage: 4 V
• Peak pulse current capacity: 250 A (8/20µs) and 80 A (10/1000µs)
• Hold current: 150 mA
• Element count: 4 elements
• Capacitance range: 50pF to 85pF
• Package configuration: 6-SMD, gull wing form factor
• Mounting technology: Surface mount

The P2304UBLRP meets all these criteria and is therefore a direct electrical and mechanical equivalent. The primary distinction between these parts is packaging format and product lifecycle status.

Parameter Comparison

Engineering Selection Recommendations

The P2304UBLRP is the direct substitute for the obsolete P2304UBRP. Both parts are electrically and mechanically identical across all specified parameters. Selection between these parts should be based on the following factors:

For new designs and ongoing production requiring current component availability, the P2304UBLRP is the appropriate choice. This part carries active product status and is available in tape and reel packaging, which is standard for automated assembly operations.

The P2304UBLRP provides improved regulatory compliance with ROHS3 certification, whereas the P2304UBRP is RoHS non-compliant. Both parts maintain identical moisture sensitivity levels and export classifications.

Existing designs currently using the P2304UBRP can transition to the P2304UBLRP without circuit modification, as all electrical characteristics and package dimensions remain unchanged.

Frequently Asked Questions (FAQ)

Q: Can the P2304UBLRP be used as a direct replacement for the P2304UBRP in existing designs?
