P0900SCRP Equivalent & Substitute Parts

Part Overview

The P0900SCRP is a 75V off-state, 400A peak pulse TVS thyristor manufactured by Littelfuse Inc. in the DO-214AA (SMB) surface mount package. This component belongs to the SIDACtor® series of transient voltage suppressors and is classified as obsolete. Due to its obsolete status and limited availability relative to active alternatives, identifying equivalent substitute parts is essential for ongoing design support and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the P0900SCRP is determined by electrical and mechanical parameter equivalence within the TVS thyristor category. The following parameters define acceptable substitutes:

• Voltage ratings (off-state, breakover, and on-state) must match exactly
• Peak pulse current ratings (8/20µs and 10/1000µs) must match exactly
• Hold current (Ih) must match exactly
• Capacitance must match exactly
• Package type (DO-214AA, SMB) must be identical
• Mounting type (surface mount) must be identical
• Number of elements must be identical

The P0900SCLRP meets all these criteria and qualifies as a direct electrical and mechanical equivalent.

Parameter Comparison

Engineering Selection Recommendations

The P0900SCLRP is the direct substitute for the P0900SCRP. Both components are manufactured by Littelfuse and share identical electrical and mechanical specifications. The primary differences are product status and compliance certifications.

The P0900SCRP is obsolete, whereas the P0900SCLRP is active and maintains current production status. The P0900SCLRP carries ROHS3 compliance and REACH unaffected status, providing regulatory alignment for new designs and ongoing production. The P0900SCLRP is available in Tape & Reel packaging, suitable for automated assembly processes, with significantly higher inventory availability (3900 units versus 899 units).

For applications currently using the P0900SCRP, transition to the P0900SCLRP is supported by complete electrical equivalence and identical package geometry.

Frequently Asked Questions (FAQ)

Q: Are the P0900SCRP and P0900SCLRP electrically interchangeable?

A: Yes. Both components have identical voltage ratings (75V off-state, 98V breakover, 4V on-state), peak pulse current ratings (400A at 8/20µs, 100A at 10/1000µs), hold current (150mA), and capacitance (140pF). They are direct electrical equivalents.

Q: Can the P0900SCLRP be used as a drop-in replacement for the P0900SCRP?

A: Yes. Both components use the DO-214AA (SMB) surface mount package with identical pin configuration and footprint. No PCB layout modifications are required.

Q: What is the difference between the P0900SCRP and P0900SCLRP packaging?

A: The P0900SCRP is supplied in bulk packaging, while the P0900SCLRP is supplied in Tape & Reel (TR) format. Tape & Reel packaging is optimized for automated pick-and-place assembly. Both formats contain the same component.

Q: Why is the P0900SCRP listed as obsolete?

A: The P0900SCRP has been discontinued by the manufacturer. The P0900SCLRP is the active production equivalent and is recommended for all new designs and ongoing production requirements.

Q: Does the P0900SCLRP meet RoHS compliance requirements?

A: Yes. The P0900SCLRP is ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards. The P0900SCRP is RoHS non-compliant.

Q: Are there any other substitute parts for the P0900SCRP?

A: Based on the provided specifications, the P0900SCLRP is the only listed direct substitute that meets all electrical and mechanical parameter requirements for the P0900SCRP.
