P1300EARP2 Equivalent & Substitute Parts

Part Overview

The P1300EARP2 is a 120V 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 and TO-92-2 package configurations. The P1300EARP2 is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing design support and procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the P1300EARP2 is determined by electrical and mechanical parameter equivalence. The critical parameters defining substitutability are:

• Voltage ratings: Breakover voltage (160V), off-state voltage (120V), and on-state voltage (4V)
• Current specifications: Peak pulse current at 8/20µs (150A) and 10/1000µs (45A), and hold current (150mA)
• Physical characteristics: Single-element configuration, 45pF capacitance, through-hole mounting
• Package compatibility: TO-226-2 and TO-92-2 form factors with formed leads

The P1300EALRP2 meets all electrical and mechanical requirements for direct substitution. The primary distinction between these parts is packaging format and product status.

Engineering Selection Recommendations

The P1300EALRP2 is the direct functional equivalent of the P1300EARP2. Both parts share identical electrical specifications and package configurations. Selection between these parts should be based on the following factors:

Product Status: The P1300EARP2 is obsolete, while the P1300EALRP2 is active. For new designs or long-term production requirements, the P1300EALRP2 is the appropriate choice to ensure continued component availability.

Compliance: The P1300EALRP2 is ROHS3 compliant, whereas the P1300EARP2 is RoHS non-compliant. Applications subject to RoHS regulations require the P1300EALRP2.

Packaging: The P1300EARP2 is supplied in bulk packaging, while the P1300EALRP2 is supplied in tape and reel format. Packaging selection depends on production volume and assembly process requirements.

Frequently Asked Questions (FAQ)

Q: Can the P1300EALRP2 replace the P1300EARP2 in existing designs?

A: Yes. The P1300EALRP2 is electrically and mechanically equivalent to the P1300EARP2. All voltage ratings, current specifications, and package dimensions are identical. Direct substitution is possible without circuit modification.

Q: What is the difference between the P1300EARP2 and P1300EALRP2?

A: The parts are electrically identical. The primary differences are product status (obsolete vs. active), packaging format (bulk vs. tape and reel), and RoHS compliance status (non-compliant vs. ROHS3 compliant).

Q: Are there any compatibility issues when switching from P1300EARP2 to P1300EALRP2?

A: No compatibility issues exist. Both parts use the same TO-226-2 and TO-92-2 package configurations with formed leads. PCB footprints and mounting procedures are identical.

Q: Why is the P1300EARP2 obsolete?

A: The P1300EARP2 has been superseded by the P1300EALRP2. The active part number provides improved compliance status and continued manufacturing support.

Q: Does packaging format affect electrical performance?

A: No. Tape and reel packaging (P1300EALRP2) and bulk packaging (P1300EARP2) do not affect component electrical characteristics. Packaging format is a logistics and assembly consideration only.

Q: Is the P1300EALRP2 suitable for RoHS-regulated applications?

A: Yes. The P1300EALRP2 is ROHS3 compliant and meets RoHS regulatory requirements. The P1300EARP2 is not RoHS compliant.
