Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the P1301CA2RP is determined by the following critical parameters:

• Voltage - Clamping: 160V (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)
• Manufacturer: Littelfuse (same manufacturer preferred for consistency)

The P1301CA2LRP meets all electrical and mechanical substitution criteria. The primary distinction between these parts is product status and packaging configuration, not functional performance or electrical characteristics.

Parameter Comparison

Engineering Selection Recommendations

The P1301CA2LRP is the direct substitute for the P1301CA2RP. Both components are electrically and mechanically identical, with all critical parameters matching exactly.

Selection between these parts should be based on the following factors:

Product Status: The P1301CA2RP is obsolete, while the P1301CA2LRP is active. For new designs or ongoing production, the P1301CA2LRP is the appropriate choice due to continued manufacturer support and availability.

Compliance: The P1301CA2LRP is ROHS3 compliant, whereas the P1301CA2RP is RoHS non-compliant. Applications subject to RoHS regulations require the P1301CA2LRP.

Packaging: The P1301CA2RP is supplied in bulk packaging, while the P1301CA2LRP is supplied in Tape & Reel (TR) format. Packaging selection depends on assembly process requirements and volume considerations.

Supply Chain: The P1301CA2LRP has significantly higher inventory availability (3411 Pcs) compared to the P1301CA2RP (654 Pcs), supporting reliable procurement for production schedules.

Frequently Asked Questions (FAQ)

Q: Are P1301CA2RP and P1301CA2LRP electrically interchangeable?

A: Yes. Both components have identical electrical specifications, including 160V clamping voltage, mixed technology, dual circuits, and SLIC application suitability. They are direct functional equivalents.

Q: What is the difference between these two parts?

A: The primary differences are product status (obsolete vs. active), packaging format (bulk vs. Tape & Reel), and RoHS compliance status (non-compliant vs. ROHS3 compliant). Electrical and mechanical characteristics are identical.

Q: Can I use P1301CA2LRP as a replacement for P1301CA2RP in existing designs?

A: Yes. The P1301CA2LRP is a direct substitute. No circuit modifications or design changes are required. Verify that your assembly process accommodates Tape & Reel packaging if transitioning from bulk supply.

Q: Does the packaging difference affect circuit performance?

A: No. Packaging format (bulk vs. Tape & Reel) affects supply chain logistics and assembly handling only. Electrical performance and reliability are unaffected.

Q: Which part should I specify for new designs?

A: Specify the P1301CA2LRP for new designs. It is actively manufactured, widely available, and compliant with current RoHS regulations.

Q: Are there any compatibility concerns with the DO-214AA package?

A: No. Both parts use the identical DO-214AA, SMB (3 Leads), Compak package. PCB footprints, solder pad layouts, and mounting procedures are identical.
