Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the P0901CA2 is determined by strict alignment with the following critical parameters:

• Voltage - Clamping: 98V (exact match required)
• Technology: Mixed Technology (exact match required)
• Number of Circuits: 2 (exact match required)
• Applications: SLIC (exact match required)
• Package / Case: DO-214AA, SMB (3 Leads), Compak (exact match required)
• Supplier Device Package: DO-214AA (exact match required)

The P0901CA2LRP qualifies as a direct substitute because it maintains identical electrical specifications and mechanical packaging while offering improved product status and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The P0901CA2LRP is the direct substitute for the obsolete P0901CA2. Both components share identical electrical and mechanical specifications, ensuring functional equivalence in circuit protection applications.

The P0901CA2LRP offers two significant advantages over the original part:

• Active product status ensures ongoing manufacturer support and availability
• ROHS3 compliance meets current environmental and regulatory requirements, whereas the P0901CA2 is RoHS non-compliant

For new designs and production continuity, the P0901CA2LRP is the appropriate selection. The identical packaging, clamping voltage, circuit configuration, and SLIC application compatibility ensure direct replacement without design modification.

Frequently Asked Questions (FAQ)

Q: Can P0901CA2LRP be used as a direct replacement for P0901CA2?

A: Yes. Both components are identical in electrical performance (98V clamping voltage, mixed technology, dual circuits) and mechanical packaging (DO-214AA, SMB 3-lead). The P0901CA2LRP is the active production equivalent.

Q: What is the primary difference between P0901CA2 and P0901CA2LRP?

A: The P0901CA2LRP is the current production version with ROHS3 compliance and active product status. The P0901CA2 is obsolete and RoHS non-compliant. Electrical and mechanical specifications are identical.

Q: Are there packaging differences between these parts?

A: No. Both components use DO-214AA surface mount packaging with SMB 3-lead configuration. The P0901CA2LRP is supplied in Tape & Reel (TR) format, which is standard for active production parts.

Q: What does the "LRP" suffix indicate?

A: The LRP suffix denotes the Tape & Reel packaging format for the P0901CA2LRP, which is the standard distribution method for active production components.

Q: Can these parts be used interchangeably in SLIC applications?

A: Yes. Both the P0901CA2 and P0901CA2LRP are specified for SLIC applications with identical circuit protection characteristics and are mechanically and electrically interchangeable.
