Key Parameters

Substitute Part Grouping Explanation

Substitution of the P1100ECMCAP is determined by electrical and mechanical parameter equivalence. The following criteria establish valid substitutes:

Electrical Parameters (Critical):

• Voltage - Off State: 90V
• Voltage - Breakover: 130V
• Voltage - On State: 4V
• Current - Peak Pulse (8/20µs): 400A
• Current - Peak Pulse (10/1000µs): 100A
• Current - Hold (Ih): 150mA
• Capacitance: 70pF
• Number of Elements: 1

Mechanical Parameters (Critical):

• Package / Case: TO-226-2, TO-92-2 (TO-226AC) with formed leads
• Mounting Type: Through Hole

The P1100ECMCLAP meets all specified electrical and mechanical parameters, establishing it as a direct equivalent substitute.

Parameter Comparison

Engineering Selection Recommendations

The P1100ECMCLAP is the direct functional equivalent of the P1100ECMCAP. Both components share identical electrical specifications and mechanical packaging. The primary distinction is product lifecycle status: P1100ECMCAP is obsolete while P1100ECMCLAP is active production.

For new designs or component replenishment, P1100ECMCLAP is the appropriate selection. This part maintains full electrical and mechanical compatibility while offering the advantage of active manufacturer support and current availability.

The P1100ECMCLAP additionally carries ROHS3 compliance certification, whereas the P1100ECMCAP is non-compliant. This distinction is relevant for applications subject to RoHS regulatory requirements.

Frequently Asked Questions (FAQ)

Q: Can P1100ECMCLAP directly replace P1100ECMCAP in existing designs?

A: Yes. The P1100ECMCLAP provides identical electrical performance and mechanical compatibility. No circuit modifications are required.

Q: What is the difference between these two part numbers?

A: The primary differences are product status (obsolete vs. active) and packaging format. P1100ECMCAP uses standard packaging while P1100ECMCLAP is supplied in Tape & Box format. Electrical specifications and TO-226-2 package dimensions are identical.

Q: Are there any compliance differences?

A: Yes. P1100ECMCLAP is ROHS3 compliant, while P1100ECMCAP is non-compliant. For applications requiring RoHS certification, P1100ECMCLAP is the required selection.

Q: What parameters must match for a valid substitute?

A: All electrical parameters (voltage ratings, current ratings, capacitance) and mechanical parameters (package type, lead configuration, mounting method) must match exactly. The P1100ECMCLAP meets all these requirements.

Q: Is the TO-226-2 package identical between both parts?

A: Yes. Both parts use the same TO-226-2 package with formed leads and through-hole mounting. PCB footprints are identical.
