P1100EARP2 Equivalent & Substitute Parts

Part Overview

The P1100EARP2 is a 90V 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 or TO-92-2 package configurations. The P1100EARP2 is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the P1100EARP2 is determined by electrical and mechanical parameter equivalence. The critical parameters defining substitutability are:

• Voltage - Off State: 90V
• Voltage - Breakover: 130V
• Voltage - On State: 4V
• Current - Peak Pulse (8/20µs): 150A
• Current - Peak Pulse (10/1000µs): 45A
• Current - Hold (Ih): 150mA
• Capacitance: 50pF
• Number of Elements: 1
• Mounting Type: Through Hole
• Package / Case: TO-226-2, TO-92-2 (TO-226AC)

The P1100EALRP2 meets all electrical and mechanical requirements for direct substitution. The primary distinction is packaging format (Tape & Reel versus individual unit packaging) and product status (Active versus Obsolete).

Parameter Comparison

Engineering Selection Recommendations

The P1100EALRP2 is the direct functional equivalent of the P1100EARP2. Selection between these parts should be based on:

• Product Status: The P1100EALRP2 maintains Active status, ensuring continued availability and manufacturing support. The P1100EARP2 is Obsolete.
• Regulatory Compliance: The P1100EALRP2 is ROHS3 Compliant, whereas the P1100EARP2 is RoHS non-compliant. For applications subject to RoHS regulations, the P1100EALRP2 is required.
• Packaging Format: The P1100EALRP2 is supplied in Tape & Reel format, suitable for automated assembly processes. The P1100EARP2 is supplied as individual units.

All electrical and mechanical parameters are identical between the two parts, confirming direct substitutability for circuit-level performance.

Frequently Asked Questions (FAQ)

Q: Can the P1100EALRP2 replace the P1100EARP2 in existing designs?

A: Yes. The P1100EALRP2 is electrically and mechanically equivalent to the P1100EARP2. All voltage ratings, current ratings, and package specifications are identical. The primary differences are product status (Active versus Obsolete) and packaging format (Tape & Reel versus individual units).

Q: What is the difference between the packaging formats?

A: The P1100EARP2 is supplied as individual units in standard packaging. The P1100EALRP2 is supplied in Tape & Reel format, which is optimized for high-volume automated assembly processes. Both formats contain the same component with identical electrical characteristics.

Q: Are there RoHS compliance differences?

A: Yes. The P1100EALRP2 is ROHS3 Compliant, while the P1100EARP2 is RoHS non-compliant. For applications requiring RoHS compliance, the P1100EALRP2 must be used.

Q: Will the P1100EALRP2 fit the same PCB footprint as the P1100EARP2?

A: Yes. Both parts use the TO-226-2 or TO-92-2 package with formed leads. PCB footprints and mounting requirements are identical.

Q: Is the P1100EALRP2 available in the same quantities as the P1100EARP2?

A: Availability varies by supplier and time. The P1100EALRP2 maintains Active product status, indicating ongoing manufacturing and distribution. The P1100EARP2 is Obsolete and availability is limited to existing inventory.
