P0900EARP2 Equivalent & Substitute Parts

Part Overview

The P0900EARP2 is a 75V off-state, 150A peak pulse TVS thyristor manufactured by Littelfuse Inc. in the SIDACtor® series. This component is designed for transient voltage suppression applications requiring through-hole mounting in TO-226-2 package configuration. The part is currently classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing design support and component procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the P0900EARP2 is determined by electrical and mechanical parameter equivalence across the following criteria:

• Voltage ratings: Off-state voltage (75V), breakover voltage (98V), and on-state voltage (4V) must match exactly
• Current specifications: Peak pulse current at 8/20µs (150A) and 10/1000µs (45A) must be identical
• Hold current (Ih): 150mA requirement must be maintained
• Capacitance: 55pF specification must be preserved
• Package compatibility: TO-226-2 / TO-92-2 through-hole mounting must be retained
• Element count: Single element configuration must be maintained

The P0900EALRP2 meets all these criteria and qualifies as a direct electrical and mechanical substitute.

Parameter Comparison

Engineering Selection Recommendations

The P0900EALRP2 is the direct substitute for the obsolete P0900EARP2. Both parts share identical electrical specifications and package configuration, ensuring pin-for-pin and functional compatibility.

The primary distinction between these parts is product status and compliance posture. The P0900EARP2 is obsolete and RoHS non-compliant, while the P0900EALRP2 is active production and ROHS3 compliant. The P0900EALRP2 also carries REACH unaffected status.

For new designs or component replenishment, the P0900EALRP2 is the appropriate selection. For legacy system maintenance where the original P0900EARP2 specification must be preserved, the P0900EALRP2 provides electrical and mechanical equivalence with improved regulatory compliance.

Frequently Asked Questions (FAQ)

Q: Can P0900EALRP2 be used as a direct replacement for P0900EARP2?

A: Yes. Both parts are electrically and mechanically identical across all specified parameters: 75V off-state voltage, 98V breakover voltage, 150A peak pulse current (8/20µs), 45A peak pulse current (10/1000µs), 150mA hold current, 55pF capacitance, and TO-226-2 / TO-92-2 package configuration. Pin-for-pin substitution is valid.

Q: What is the difference between P0900EARP2 and P0900EALRP2?

A: The parts are electrically identical. The differences are: P0900EARP2 is obsolete and RoHS non-compliant; P0900EALRP2 is active production and ROHS3 compliant. P0900EALRP2 also carries REACH unaffected status. The packaging differs: P0900EARP2 is supplied loose, while P0900EALRP2 is supplied in tape and reel format.

Q: Are there any package or mounting differences?

A: No. Both parts use identical through-hole mounting in TO-226-2 / TO-92-2 package configuration. PCB layout and assembly procedures remain unchanged.

Q: Why is the P0900EARP2 obsolete?

A: The P0900EARP2 is classified as obsolete by the manufacturer. The P0900EALRP2 represents the current production equivalent with identical electrical performance and improved regulatory compliance.

Q: What is the inventory status?

A: P0900EARP2 has 824 pieces in stock as new original inventory. P0900EALRP2 has 883 pieces in stock as new original inventory.
