Key Parameters

Substitute Part Grouping Explanation

Substitution of the P0901CA2RP is determined by strict equivalence across the following critical parameters:

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

The substitute part P0901CA2LRP meets all these criteria and is manufactured by the same supplier (Littelfuse Inc.), ensuring functional and mechanical compatibility with designs originally specified for the P0901CA2RP.

Parameter Comparison

Engineering Selection Recommendations

The P0901CA2LRP is the direct substitute for the obsolete P0901CA2RP. Both parts are functionally and mechanically equivalent across all critical electrical and physical parameters.

Key distinctions between the two parts:

• Product Status: The P0901CA2RP is obsolete, while P0901CA2LRP is active and currently in production.
• RoHS Compliance: The P0901CA2LRP meets ROHS3 compliance standards, whereas the P0901CA2RP is non-compliant. This distinction is relevant for applications subject to RoHS regulatory requirements.
• Packaging Format: The P0901CA2RP is supplied in bulk packaging, while P0901CA2LRP is supplied in Tape & Reel (TR) format, which is standard for automated assembly processes.
• Supply Availability: The P0901CA2LRP has significantly higher inventory availability (3702 units) compared to the P0901CA2RP (830 units).

For new designs or ongoing production requiring this component specification, the P0901CA2LRP is the appropriate selection.

Frequently Asked Questions (FAQ)

Q: Can P0901CA2LRP be used as a direct replacement for P0901CA2RP in existing designs?

A: Yes. The P0901CA2LRP is electrically and mechanically equivalent to the P0901CA2RP. Both devices share identical clamping voltage (98V), circuit count (2), package type (DO-214AA), and application specifications (SLIC). Pin configuration and footprint are identical, enabling direct substitution without design modification.

Q: What is the difference between the bulk and Tape & Reel packaging formats?

A: Bulk packaging (P0901CA2RP) is suitable for manual assembly or small-volume applications. Tape & Reel packaging (P0901CA2LRP) is designed for automated pick-and-place assembly processes and is the standard format for high-volume production. Both formats contain the same component.

Q: Does the RoHS3 compliance of P0901CA2LRP affect its electrical performance compared to the non-compliant P0901CA2RP?

A: No. RoHS compliance relates to material composition and environmental restrictions, not electrical performance. Both parts meet identical electrical specifications for clamping voltage, circuit configuration, and transient suppression characteristics.

Q: Are there any moisture sensitivity considerations when substituting these parts?

A: Both the P0901CA2RP and P0901CA2LRP have an MSL rating of 1 (Unlimited), indicating no moisture sensitivity restrictions. Storage and handling requirements are identical for both parts.

Q: What is the REACH status of the P0901CA2LRP?

A: The P0901CA2LRP is REACH Unaffected, indicating compliance with REACH regulatory requirements for substances of concern.
