P1101SA Equivalent & Substitute Parts

Part Overview

The P1101SA is a Transient Voltage Suppressors (TVS) device manufactured by Littelfuse Inc., designed for circuit protection in SLIC applications. This device operates at a clamping voltage of 130V and utilizes mixed technology in a DO-214AA surface mount package. The P1101SA is classified as obsolete, making identification of suitable substitute parts essential for ongoing design support and component procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the P1101SA is determined by the following critical parameters:

• Voltage - Clamping (130V): The substitute must maintain identical clamping voltage to ensure equivalent transient protection performance
• Package / Case (DO-214AA, SMB): Physical and electrical compatibility requires matching package type for PCB layout and thermal characteristics
• Technology (Mixed Technology): The substitute must employ the same technology classification to preserve electrical behavior
• Number of Circuits (1): Single-circuit configuration must be maintained
• Mounting Type (Surface Mount): Surface mount compatibility is required for assembly compatibility
• Applications (SLIC): The substitute must be rated for SLIC applications

The P1101SALRP meets all substitution criteria and is classified as an active product, providing a viable replacement for the obsolete P1101SA.

Parameter Comparison

Engineering Selection Recommendations

The P1101SALRP is the direct substitute for the P1101SA. Both devices share identical electrical specifications (130V clamping voltage, mixed technology, single circuit) and mechanical compatibility (DO-214AA package, surface mount). The primary distinction is product status and compliance:

• P1101SA: Obsolete status restricts procurement and long-term availability
• P1101SALRP: Active product status ensures continued supply and manufacturing support

The P1101SALRP additionally provides ROHS3 compliance, whereas the P1101SA is RoHS non-compliant. For new designs or component replenishment, the P1101SALRP is the appropriate selection. Both devices maintain identical moisture sensitivity levels and export classifications.

Frequently Asked Questions (FAQ)

Q: Can P1101SALRP be used as a direct replacement for P1101SA?

A: Yes. Both devices are manufactured by Littelfuse Inc. and share identical electrical parameters (130V clamping voltage, mixed technology, single circuit) and mechanical specifications (DO-214AA package, surface mount). The P1101SALRP is the active product variant.

Q: What is the primary reason to substitute P1101SA with P1101SALRP?

A: The P1101SA is classified as obsolete, limiting procurement availability. The P1101SALRP is an active product from the same manufacturer with identical functional specifications, ensuring continued supply and manufacturing support.

Q: Are there packaging differences between these parts?

A: No. Both devices use the DO-214AA (SMB) surface mount package. PCB layout and assembly processes remain unchanged.

Q: Does the RoHS compliance difference affect electrical performance?

A: No. RoHS compliance is a manufacturing and environmental standard. Electrical performance and clamping characteristics remain identical between P1101SA and P1101SALRP.

Q: What is the packaging format for P1101SALRP?

A: P1101SALRP is supplied in Tape & Reel (TR) format, suitable for automated assembly processes.
