P1101SC Equivalent & Substitute Parts

Part Overview

The P1101SC is a Transient Voltage Suppressors (TVS) device manufactured by Littelfuse Inc., designed for circuit protection applications in SLIC systems. This device operates at a clamping voltage of 130V and utilizes mixed technology in a DO-214AA surface mount package. The P1101SC is classified as obsolete, making identification of suitable substitute parts essential for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the P1101SC is determined by strict equivalence across the following parameters:

• Voltage - Clamping: 130V (exact match required)
• Technology: Mixed Technology (functional requirement)
• Number of Circuits: 1 (functional requirement)
• Package / Case: DO-214AA, SMB (mechanical and electrical interface requirement)
• Mounting Type: Surface Mount (assembly compatibility requirement)
• Applications: SLIC (application-specific requirement)
• Moisture Sensitivity Level: 1 (Unlimited) (environmental handling requirement)

The P1101SCLRP meets all substitution criteria as a direct equivalent part from the same manufacturer with identical electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

The P1101SCLRP is a direct functional equivalent to the P1101SC with identical electrical and mechanical specifications. The primary distinction is product status: the P1101SC is obsolete while the P1101SCLRP is active. The P1101SCLRP additionally provides ROHS3 compliance, whereas the P1101SC is RoHS non-compliant. For new designs and ongoing system support, the P1101SCLRP is the appropriate selection due to its active product status and regulatory compliance posture.

Frequently Asked Questions (FAQ)

Q: Can the P1101SCLRP directly replace the P1101SC in existing designs?

A: Yes. Both parts share identical electrical specifications (130V clamping voltage, mixed technology, single circuit) and mechanical specifications (DO-214AA package, surface mount). PCB layout and assembly processes require no modification.

Q: What is the significance of the product status difference?

A: The P1101SC is classified as obsolete, indicating Littelfuse Inc. has discontinued production and support. The P1101SCLRP is active, ensuring ongoing availability, technical support, and supply chain continuity.

Q: Does the RoHS compliance difference affect substitution?

A: RoHS compliance is a regulatory and procurement consideration rather than a functional one. Both parts perform identically in circuit operation. The P1101SCLRP's ROHS3 compliance may be required depending on application region and customer specifications.

Q: Are there packaging differences between these parts?

A: The P1101SC packaging is not specified in available data. The P1101SCLRP is supplied in Cut Tape (CT) and Digi-Reel® packaging. Both parts use the DO-214AA, SMB package format for the component itself.

Q: What is the inventory status for these parts?

A: The P1101SC has 30,400 pieces in stock. The P1101SCLRP has 17,084 pieces in stock. Both are available as new original components.
