NP1100SCMCT3G Equivalent & Substitute Parts

Part Overview

The NP1100SCMCT3G is a 90V off-state, 400A peak pulse TVS thyristor manufactured by onsemi in DO-214AA (SMB) surface mount package. This component is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and procurement continuity. The part functions as a transient voltage suppressor for circuit protection applications requiring high current handling capability.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the NP1100SCMCT3G is determined by the following critical parameters:

• Voltage - Off State: Must be 90V
• Package / Case: Must be DO-214AA, SMB
• Mounting Type: Must be Surface Mount
• Number of Elements: Must be 1
• Current - Hold (Ih): Must be 150mA

Substitute parts are grouped into two categories:

Direct Equivalents maintain all critical electrical parameters including 400A peak pulse current (8/20µs) and 100A peak pulse current (10/1000µs). These parts provide full functional replacement.

Similar Alternatives maintain voltage and package specifications but may have reduced peak pulse current ratings (250A at 8/20µs). These parts are suitable for applications where the full 400A rating is not required.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalents for Full Replacement:

P1100SCLRP (Littelfuse Inc.) and P1100SCMCLRP (Littelfuse) are active production parts that maintain the 400A peak pulse current specification. Both are RoHS3 compliant and have unlimited moisture sensitivity level. P1100SCLRP is available in Cut Tape and Digi-Reel packaging, while P1100SCMCLRP is supplied in Tape & Reel format. The primary difference is capacitance (115pF vs. 70pF) and on-state voltage (4V vs. 5V).

SMP100LC-90 (STMicroelectronics) maintains 400A peak pulse current with a breakover voltage of 125V (5V lower than the original). This part is RoHS3 compliant and active in production.

Alternative for Reduced Current Applications:

TB1100M-13-F (Diodes Incorporated) is an active production part with reduced peak pulse current (250A at 8/20µs, 50A at 10/1000µs). This part is suitable only for applications where the full 400A rating is not required. TB1100M-13 (same manufacturer) is discontinued at DiGi Electronics and should be avoided for new designs.

Limited Current Capability:

TISP4C115H3BJR-S (Bourns Inc.) has the lowest peak pulse current specification (100A at 10/1000µs) and lacks the 8/20µs rating. This part is suitable only for low-current transient suppression applications. REACH status is affected for this part.

Frequently Asked Questions (FAQ)

Q: Can P1100SCLRP directly replace NP1100SCMCT3G?

A: Yes. Both parts share identical voltage ratings (90V off-state, 130V breakover), current specifications (400A peak pulse at 8/20µs, 100A at 10/1000µs), hold current (150mA), and DO-214AA SMB package. P1100SCLRP is active in production, addressing the obsolescence of the original part.

Q: What is the difference between P1100SCLRP and P1100SCMCLRP?

A: Both are Littelfuse SIDACtor® parts with identical current ratings and voltage specifications. Differences include capacitance (115pF vs. 70pF), on-state voltage (4V vs. 5V), and packaging format (Cut Tape/Digi-Reel vs. Tape & Reel). Selection depends on packaging requirements and circuit capacitance tolerance.

Q: Can TB1100M-13-F be used as a substitute?

A: TB1100M-13-F is suitable only if the application does not require the full 400A peak pulse current. This part is rated for 250A at 8/20µs and 50A at 10/1000µs. Verify circuit requirements before substitution.

Q: Why does SMP100LC-90 have a lower breakover voltage?

A: SMP100LC-90 has a breakover voltage of 125V compared to 130V for the original part. This 5V difference may affect trigger characteristics in specific circuit designs. Evaluate circuit performance requirements before selection.

Q: Are all substitute parts RoHS compliant?

A: P1100SCLRP, P1100SCMCLRP, SMP100LC-90, TB1100M-13-F, and TISP4C115H3BJR-S are RoHS3 compliant. TB1100M-13 is RoHS non-compliant and discontinued.

Q: What packaging options are available?

A: All substitute parts use DO-214AA (SMB) surface mount package. Packaging formats vary: P1100SCLRP is available in Cut Tape and Digi-Reel; P1100SCMCLRP, SMP100LC-90, TB1100M-13-F, and TISP4C115H3BJR-S are supplied in Tape & Reel.

Q: Which substitute has the best inventory availability?

A: TISP4C115H3BJR-S has the highest reported inventory (6200 pcs). SMP100LC-90 has 1873 pcs, P1100SCLRP has 2700 pcs, and P1100SCMCLRP has 1246 pcs available.
