P1101CA2RP Equivalent & Substitute Parts

Part Overview

The P1101CA2RP is a Transient Voltage Suppressor (TVS) device manufactured by Littelfuse Inc., designed for circuit protection applications in SLIC (Subscriber Line Interface Circuit) systems. This component features mixed technology with a 130V clamping voltage and dual-circuit configuration in a surface-mount DO-214AA package.

The P1101CA2RP is classified as obsolete. Locating equivalent substitute parts is necessary to maintain design continuity and ensure component availability for new production runs, repairs, and system upgrades where this device is specified.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the P1101CA2RP are identified based on strict electrical and mechanical parameter matching:

Critical Parameters for Substitution:

• 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)

The P1101CA2LRP meets all substitution criteria. Both parts share identical electrical specifications and mechanical packaging, differing only in product status and packaging format (Tape & Reel versus standard packaging).

Parameter Comparison

Engineering Selection Recommendations

The P1101CA2LRP is the direct substitute for the obsolete P1101CA2RP. Both components are electrically and mechanically identical, with all critical parameters matching exactly.

Key Advantages of P1101CA2LRP:

• Active product status ensures long-term availability and supply chain continuity
• ROHS3 compliance meets current environmental and regulatory requirements
• Tape & Reel packaging format supports automated assembly processes
• Identical electrical performance and mechanical fit in existing designs

Compliance Considerations: The P1101CA2RP is RoHS non-compliant, while the P1101CA2LRP is ROHS3 compliant. For new designs or applications subject to RoHS regulations, the P1101CA2LRP is the appropriate selection. Both parts maintain identical moisture sensitivity levels and export classifications.

Frequently Asked Questions (FAQ)

Q: Can P1101CA2LRP be used as a direct replacement for P1101CA2RP?

A: Yes. Both parts are electrically and mechanically identical. The P1101CA2LRP is the active production equivalent of the obsolete P1101CA2RP, with identical clamping voltage (130V), circuit configuration (2 circuits), and DO-214AA package specifications.

Q: What is the difference between P1101CA2RP and P1101CA2LRP?

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

Q: Is the DO-214AA package compatible with existing PCB designs?

A: Yes. Both the P1101CA2RP and P1101CA2LRP use the same DO-214AA, SMB (3 Leads), Compak package. No PCB layout modifications are required when substituting between these parts.

Q: Does the Tape & Reel packaging of P1101CA2LRP affect circuit performance?

A: No. Tape & Reel is a supply format for automated assembly. It does not affect electrical performance, reliability, or circuit functionality. The component itself is identical to standard packaging formats.

Q: Are there any compliance differences between these parts?

A: The P1101CA2LRP is ROHS3 compliant, while the P1101CA2RP is RoHS non-compliant. Both parts are classified as EAR99 for export control and share identical HTSUS codes. For applications requiring RoHS compliance, the P1101CA2LRP is the appropriate selection.

Q: What is the moisture sensitivity level for these TVS devices?

A: Both parts have a Moisture Sensitivity Level (MSL) of 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.
