P1100ECMC Equivalent & Substitute Parts

Part Overview

The P1100ECMC is a 90V off-state TVS thyristor manufactured by Littelfuse Inc. in the SIDACtor® series, designed for transient voltage suppression applications. This component features a TO-226-2 package configuration with 400A peak pulse current capability (8/20µs). The P1100ECMC is classified as obsolete, making identification of active equivalent parts essential for ongoing design support and procurement continuity.

Substitute Part Grouping Explanation

Substitution of the P1100ECMC is determined by electrical and mechanical parameter equivalence within the SIDACtor® TVS thyristor category. The following parameters establish substitution validity:

• Voltage - Off State: 90V (exact match required)
• Voltage - Breakover: 130V (exact match required)
• Voltage - On State: 4V (exact match required)
• Current - Peak Pulse (8/20µs): 400A (exact match required)
• Current - Peak Pulse (10/1000µs): 100A (exact match required)
• Current - Hold (Ih): 150mA (exact match required)
• Capacitance: 70pF (exact match required)
• Package / Case: TO-226-2, TO-92-2 (TO-226AC) (exact match required)
• Mounting Type: Through Hole (exact match required)

The P1100ECMCL qualifies as a direct substitute based on complete electrical and mechanical parameter alignment with the P1100ECMC.

Parameter Comparison

Engineering Selection Recommendations

The P1100ECMCL is the direct substitute for the obsolete P1100ECMC. Both components share identical electrical specifications and package configurations. The P1100ECMCL offers the additional advantage of active product status, ensuring continued availability and supply chain support. The P1100ECMCL meets ROHS3 compliance requirements, whereas the P1100ECMC does not. For new designs or component replacement in existing applications, the P1100ECMCL is the appropriate selection based on product lifecycle status and regulatory compliance.

Frequently Asked Questions (FAQ)

Q: Can the P1100ECMCL directly replace the P1100ECMC in existing applications?

A: Yes. The P1100ECMCL provides identical electrical performance and package compatibility. All voltage ratings, current specifications, and physical dimensions match the P1100ECMC exactly.

Q: What is the primary difference between these two parts?

A: The P1100ECMC is obsolete, while the P1100ECMCL is active. The P1100ECMCL also meets ROHS3 compliance standards, whereas the P1100ECMC does not.

Q: Are there any package or mounting differences?

A: No. Both parts use the TO-226-2 package with through-hole mounting. Physical installation and PCB layout remain unchanged.

Q: What does the "L" designation in P1100ECMCL indicate?

A: The "L" suffix indicates bulk packaging. This is a packaging variation only and does not affect electrical or mechanical specifications.

Q: Is the moisture sensitivity level the same for both parts?

A: Yes. Both components have MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.
