Key Parameters

Substitute Part Grouping Explanation

Substitution of the P0900ECMCAP is determined by electrical and mechanical parameter equivalence. The critical parameters for substitution are:

• Voltage - Off State: 75V
• Voltage - Breakover: 98V
• Voltage - On State: 4V
• Current - Peak Pulse (8/20µs): 400A
• Current - Peak Pulse (10/1000µs): 100A
• Current - Hold (Ih): 150mA
• Capacitance: 70pF
• Package / Case: TO-226-2, TO-92-2 (TO-226AC)
• Mounting Type: Through Hole

The P0900ECMCLAP meets all electrical specifications and mechanical requirements, differing only in product status and packaging configuration.

Parameter Comparison

Engineering Selection Recommendations

The P0900ECMCLAP is the direct substitute for the P0900ECMCAP. Both components share identical electrical specifications and mechanical packaging. The primary distinction is product status: P0900ECMCAP is obsolete while P0900ECMCLAP maintains active status with current manufacturing support.

For new designs and ongoing system support, P0900ECMCLAP is the appropriate selection. This part carries ROHS3 compliance, meeting current regulatory requirements, whereas the original P0900ECMCAP does not. Both components maintain identical moisture sensitivity levels and export classifications.

Frequently Asked Questions (FAQ)

Q: Can P0900ECMCLAP directly replace P0900ECMCAP in existing applications?

A: Yes. Both parts are electrically and mechanically identical across all specified parameters including voltage ratings, current ratings, capacitance, and package configuration.

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

A: The primary differences are product status (obsolete vs. active) and RoHS compliance (non-compliant vs. ROHS3 compliant). Electrical and mechanical specifications are identical.

Q: Are there packaging differences between these parts?

A: P0900ECMCAP uses standard packaging while P0900ECMCLAP is supplied in Tape & Box (TB) configuration. Both use TO-92-2 supplier device packaging and are compatible with TO-226-2 and TO-92-2 footprints.

Q: Does the RoHS compliance difference affect circuit performance?

A: No. RoHS compliance relates to material composition and regulatory requirements, not electrical performance. Both parts deliver identical functional characteristics.

Q: What is the moisture sensitivity level for these components?

A: Both parts carry MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.
