Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the P1101CA2 is determined by strict equivalence across the following critical parameters:

• Voltage - Clamping: 130V (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)
• Series: TwinSLIC™ (exact match required)
• Applications: SLIC (exact match required)

The P1101CA2LRP qualifies as a direct substitute because it maintains identical electrical specifications, circuit configuration, and mechanical packaging. The primary distinction is packaging format (Tape & Reel versus bulk) and product status (Active versus Obsolete).

Parameter Comparison

Engineering Selection Recommendations

The P1101CA2LRP is the direct equivalent substitute for the P1101CA2. Both parts share identical electrical and mechanical specifications, ensuring functional compatibility in SLIC circuit protection applications.

The P1101CA2LRP offers two significant advantages:

• Active product status ensures ongoing manufacturer support and availability
• ROHS3 compliance satisfies modern environmental and regulatory requirements, whereas the P1101CA2 is RoHS non-compliant

Selection of P1101CA2LRP is appropriate for new designs, production continuity, and replacement applications where regulatory compliance is required. The Tape & Reel packaging format of P1101CA2LRP is standard for automated assembly processes and high-volume manufacturing.

Frequently Asked Questions (FAQ)

Q: Can P1101CA2LRP be used as a direct replacement for P1101CA2?

A: Yes. Both parts are electrically and mechanically identical. They share the same 130V clamping voltage, dual-circuit configuration, mixed-technology design, and DO-214AA package. The primary differences are packaging format and product status.

Q: What is the difference between P1101CA2 and P1101CA2LRP?

A: The P1101CA2 is supplied in bulk packaging and carries Obsolete status. The P1101CA2LRP is supplied in Tape & Reel format and maintains Active product status. Additionally, P1101CA2LRP is ROHS3 compliant, while P1101CA2 is RoHS non-compliant.

Q: Is Tape & Reel packaging compatible with my assembly process?

A: Tape & Reel packaging is the standard format for automated surface mount assembly. If your process uses manual or semi-automated placement, confirm that your equipment supports 8mm or 12mm tape widths and standard reel specifications for the DO-214AA package.

Q: Does the RoHS compliance difference affect electrical performance?

A: No. RoHS compliance relates to material composition and environmental standards, not electrical function. Both parts deliver identical clamping voltage and circuit protection performance.

Q: Are there any other Littelfuse TwinSLIC™ 130V TVS alternatives?

A: Based on the provided data, P1101CA2LRP is the only documented direct substitute. Any alternative would require matching all critical parameters: 130V clamping voltage, mixed technology, dual circuits, DO-214AA package, and SLIC application designation.
