P1101SARP Equivalent & Substitute Parts

Part Overview

The P1101SARP is a Transient Voltage Suppressor (TVS) device manufactured by Littelfuse Inc., designed for SLIC applications with a clamping voltage of 130V. This component is classified as obsolete, which necessitates identification of active equivalent parts to maintain design continuity and ensure supply chain availability. The part operates using mixed technology in a DO-214AA surface mount package.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the P1101SARP is determined by strict equivalence across the following critical parameters:

• Voltage - Clamping: 130V (exact match required)
• Technology: Mixed Technology (functional equivalence)
• Number of Circuits: 1 (single circuit configuration)
• Package / Case: DO-214AA, SMB (physical and electrical compatibility)
• Mounting Type: Surface Mount (assembly process compatibility)
• Applications: SLIC (application-specific requirement)

The P1101SALRP meets all substitution criteria as a direct equivalent. Both parts share identical electrical specifications, package geometry, and application requirements. The primary distinction is product status: P1101SALRP is active and available, whereas P1101SARP is obsolete.

Parameter Comparison

Engineering Selection Recommendations

The P1101SALRP is the direct substitute for the obsolete P1101SARP. Both parts are manufactured by Littelfuse Inc. and maintain identical electrical and mechanical specifications across all critical parameters.

Key considerations for selection:

• P1101SALRP is currently active and available in production quantities (3247 Pcs in stock versus 1049 Pcs for the obsolete P1101SARP).
• P1101SALRP achieves ROHS3 compliance, whereas P1101SARP is RoHS non-compliant. This distinction is relevant for applications subject to RoHS regulations.
• P1101SALRP includes REACH Unaffected status, providing additional regulatory clarity.
• Both parts share identical packaging (Tape & Reel available for P1101SALRP), moisture sensitivity level, and export classification.

For new designs or component refresh cycles, P1101SALRP is the appropriate selection. For existing inventory management of P1101SARP, P1101SALRP provides direct functional and physical compatibility.

Frequently Asked Questions (FAQ)

Q: Can P1101SALRP be used as a direct replacement for P1101SARP in existing designs?

A: Yes. Both parts are electrically and mechanically equivalent across all specified parameters: 130V clamping voltage, mixed technology, single circuit configuration, DO-214AA package, and SLIC application compatibility. No circuit modifications are required.

Q: What is the difference between P1101SARP and P1101SALRP?

A: The primary differences are product status (P1101SARP is obsolete; P1101SALRP is active) and regulatory compliance (P1101SALRP is ROHS3 compliant and REACH Unaffected, while P1101SARP is RoHS non-compliant). Electrical and mechanical specifications are identical.

Q: Are there packaging differences between these parts?

A: Both parts use the DO-214AA, SMB package. P1101SALRP is available in Tape & Reel (TR) packaging, which is standard for active production parts. Package geometry and pin configuration are identical.

Q: Why is P1101SARP listed as obsolete?

A: Product obsolescence is determined by the manufacturer based on market demand and production decisions. P1101SALRP represents the active equivalent in Littelfuse's current product portfolio.

Q: What is the moisture sensitivity level for these parts?

A: Both P1101SARP and P1101SALRP have a Moisture Sensitivity Level (MSL) of 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.

Q: Are there any compliance certifications that differ between these parts?

A: Yes. P1101SALRP is ROHS3 compliant and REACH Unaffected. P1101SARP is RoHS non-compliant. Both share the same ECCN (EAR99) and HTSUS (8541.30.0080) classifications.
