P1100SDRP Equivalent & Substitute Parts

Part Overview

The P1100SDRP is a 90V off-state, 1 kA peak pulse TVS thyristor manufactured by Littelfuse Inc. in the SIDACtor® series, housed in a DO-214AA (SMB) surface mount package. This component is designed for transient voltage suppression applications requiring high current handling capability.

The P1100SDRP is classified as obsolete. Identifying equivalent substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production or maintenance requirements for systems utilizing this component.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the P1100SDRP is determined by electrical and mechanical parameter equivalence within the TVS thyristor category. The critical parameters governing substitution are:

• Voltage - Off State: 90V
• Voltage - Breakover: 130V
• Voltage - On State: 4V
• Current - Peak Pulse (8/20µs): 1 kA
• Current - Peak Pulse (10/1000µs): 200A
• Current - Hold (Ih): 50 mA
• Capacitance: 115 pF
• Package / Case: DO-214AA, SMB
• Mounting Type: Surface Mount

The P1100SDLRP meets all electrical and mechanical requirements for direct substitution. Both parts share identical voltage ratings, current handling specifications, capacitance characteristics, and package configuration. The primary distinction is packaging format and product status.

Parameter Comparison

Engineering Selection Recommendations

The P1100SDLRP is the direct substitute for the P1100SDRP. All electrical parameters and mechanical specifications are identical. Selection between these parts should be based on the following factors:

Product Status: The P1100SDRP is obsolete. The P1100SDLRP is active and maintains current manufacturing support from Littelfuse Inc.

Compliance: The P1100SDLRP is ROHS3 compliant, whereas the P1100SDRP is non-compliant. For applications subject to RoHS regulations, the P1100SDLRP is the required choice.

Packaging: The P1100SDRP is supplied in bulk packaging. The P1100SDLRP is supplied in Tape & Reel (TR) format, which is standard for automated assembly processes.

Supply Availability: The P1100SDLRP has significantly higher inventory availability (20,200 pcs) compared to the P1100SDRP (3,800 pcs).

For new designs or ongoing production, the P1100SDLRP is the appropriate selection. For legacy system maintenance where bulk packaging is required, the P1100SDRP remains available while stock exists.

Frequently Asked Questions (FAQ)

Q: Can the P1100SDLRP replace the P1100SDRP in existing designs?

A: Yes. The P1100SDLRP is electrically and mechanically equivalent to the P1100SDRP. All voltage ratings, current specifications, capacitance values, and package dimensions are identical. Direct substitution is supported without circuit modification.

Q: What is the difference between the P1100SDRP and P1100SDLRP?

A: The primary differences are packaging format and product status. The P1100SDRP is supplied in bulk packaging and is obsolete. The P1100SDLRP is supplied in Tape & Reel format and is active. The P1100SDLRP is also ROHS3 compliant, while the P1100SDRP is not.

Q: Is the Tape & Reel packaging of the P1100SDLRP compatible with automated assembly equipment?

A: Yes. Tape & Reel (TR) packaging is the standard format for automated surface mount assembly processes. The P1100SDLRP in TR format is compatible with standard pick-and-place equipment.

Q: Are there any electrical performance differences between bulk and Tape & Reel packaged versions?

A: No. Packaging format does not affect electrical performance. Both the P1100SDRP and P1100SDLRP deliver identical electrical characteristics.

Q: Why is RoHS compliance important for this substitution?

A: RoHS compliance is a regulatory requirement in many markets. The P1100SDLRP's ROHS3 compliance ensures the component meets environmental and material restriction standards. For applications subject to RoHS regulations, the P1100SDLRP is mandatory.

Q: Can I use the P1100SDRP if RoHS compliance is not required?

A: Yes, if RoHS compliance is not a regulatory requirement for your application, the P1100SDRP remains functionally equivalent. However, the P1100SDLRP is recommended due to active product status and superior supply availability.
