P0900EARP1 Equivalent & Substitute Parts

Part Overview

The P0900EARP1 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 or TO-92-2 packages. The part is currently obsolete, making identification of active equivalent components essential for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the P0900EARP1 is determined by electrical and mechanical parameter equivalence. The critical parameters defining substitutability are:

• Voltage ratings (breakover, off-state, and on-state)
• Peak pulse current specifications (8/20µs and 10/1000µs)
• Hold current (Ih)
• Package and mounting configuration
• Number of elements
• Capacitance

The P0900EALRP1 maintains identical electrical specifications and package configuration as the P0900EARP1, differing only in packaging format (tape and reel versus individual packaging) and product status (active versus obsolete).

Parameter Comparison

Engineering Selection Recommendations

The P0900EALRP1 is the direct functional equivalent of the P0900EARP1. All electrical parameters and mechanical specifications are identical. The P0900EALRP1 is currently in active production status, whereas the P0900EARP1 is obsolete.

The P0900EALRP1 carries ROHS3 compliance certification, whereas the P0900EARP1 is non-compliant. For applications subject to RoHS requirements, the P0900EALRP1 is the appropriate selection. The primary difference between the two parts is packaging format: the P0900EALRP1 is supplied in tape and reel configuration, while the P0900EARP1 uses standard individual packaging.

Frequently Asked Questions (FAQ)

Q: Can the P0900EALRP1 replace the P0900EARP1 in existing designs?

A: Yes. The P0900EALRP1 is electrically and mechanically equivalent to the P0900EARP1. All voltage ratings, current specifications, and package dimensions are identical. The primary consideration is packaging format: the P0900EALRP1 is supplied in tape and reel, which is standard for high-volume production.

Q: What is the difference between P0900EARP1 and P0900EALRP1?

A: The parts are identical in electrical performance and physical package. The difference is packaging format (individual versus tape and reel) and product status (obsolete versus active). The P0900EALRP1 also carries ROHS3 compliance certification.

Q: Are there any pin or footprint differences between these parts?

A: No. Both parts use the TO-226-2 or TO-92-2 package configuration with identical pin assignments and footprints.

Q: Which part should be selected for new designs?

A: The P0900EALRP1 should be selected for new designs, as it is in active production and carries current compliance certifications.
