Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the P2500SCMCLRP is determined by the following critical parameters:

• Voltage - Off State: Must be 230V
• Voltage - Breakover: Must be within the specified range (290V nominal for main part)
• Current - Peak Pulse (8/20µs): Must be 400A
• Package / Case: Must be DO-214AA, SMB
• Mounting Type: Must be Surface Mount
• Number of Elements: Must be 1
• Product Status: Must be Active
• RoHS Compliance: Must be ROHS3 Compliant

Two substitute parts meet these criteria:

1. P2500SCLRP (Littelfuse Inc.) — Direct manufacturer equivalent with identical electrical specifications and packaging
2. SMP100LC-230 (STMicroelectronics) — Cross-manufacturer substitute with equivalent functional performance and compatible package

Parameter Comparison

Engineering Selection Recommendations

P2500SCLRP is the primary substitute for P2500SCMCLRP. Both parts are manufactured by Littelfuse Inc. within the SIDACtor® series and share identical electrical specifications across all critical parameters. The primary difference is capacitance (85pF versus 45pF), which may affect circuit performance in applications with specific impedance or frequency requirements. Both parts maintain Active product status, ROHS3 compliance, and unlimited moisture sensitivity rating.

SMP100LC-230 is a cross-manufacturer substitute from STMicroelectronics in the TRISIL™ series. This part meets all substitution criteria with equivalent voltage and current ratings. The breakover voltage is 285V (versus 290V), representing a 1.7% deviation within typical component tolerance ranges. The hold current is 150mA (versus 120mA), and capacitance is 60pF. This part maintains Active product status, ROHS3 compliance, and unlimited moisture sensitivity rating. Higher inventory availability (187,700 units) may support extended supply chain requirements.

Both substitute parts are suitable for direct replacement in applications where the specified electrical and mechanical parameters are compatible with circuit design requirements.

Frequently Asked Questions (FAQ)

Q: Can P2500SCLRP be used as a direct replacement for P2500SCMCLRP?

A: Yes. Both parts are manufactured by Littelfuse Inc. and share identical voltage ratings (230V off-state, 290V breakover), current ratings (400A peak pulse at 8/20µs), and package specifications (DO-214AA, SMB). The capacitance difference (85pF versus 45pF) should be evaluated against circuit design requirements.

Q: Is SMP100LC-230 compatible with P2500SCMCLRP applications?

A: SMP100LC-230 meets the core substitution criteria: 230V off-state voltage, 400A peak pulse current, and DO-214AA SMB package. The breakover voltage is 285V (1.7% lower than 290V) and hold current is 150mA (25mA higher than 120mA). These differences must be evaluated against specific application requirements.

Q: What are the key differences in capacitance between these parts?

A: P2500SCMCLRP has 45pF capacitance, P2500SCLRP has 85pF, and SMP100LC-230 has 60pF. Capacitance affects circuit impedance and frequency response. Selection should be based on circuit design specifications.

Q: Are all three parts RoHS3 compliant?

A: Yes. P2500SCMCLRP, P2500SCLRP, and SMP100LC-230 are all ROHS3 compliant with REACH Unaffected status and MSL 1 (Unlimited) moisture sensitivity rating.

Q: What packaging options are available?

A: P2500SCMCLRP is supplied in Tape & Reel (TR) packaging. P2500SCLRP is supplied in Tape & Reel (TR) packaging. SMP100LC-230 is supplied in Cut Tape (CT) and Digi-Reel® packaging. All three use the same DO-214AA, SMB package / case format for surface-mount assembly.
