Key Parameters

Substitute Part Grouping Explanation

Substitution of the P0720ECMCAP is determined by electrical and mechanical parameter equivalence. The following criteria establish valid substitutes:

• Voltage - Off State: 65V (exact match required)
• Voltage - Breakover: 88V (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: 75pF (exact match required)
• Number of Elements: 1 (exact match required)
• Mounting Type: Through Hole (exact match required)
• Package / Case: TO-226-2 or TO-92-2 (exact match required)

The P0720ECMCLAP meets all electrical and mechanical parameters specified above, establishing it as a direct equivalent substitute.

Parameter Comparison

Engineering Selection Recommendations

The P0720ECMCLAP is the direct substitute for the obsolete P0720ECMCAP. Both components share identical electrical specifications and mechanical form factors. The P0720ECMCLAP offers the advantage of active product status, ensuring continued availability and supply chain reliability. Additionally, the P0720ECMCLAP meets ROHS3 compliance requirements, whereas the P0720ECMCAP is non-compliant. For new designs or system replacements, the P0720ECMCLAP is the appropriate selection. For legacy system maintenance requiring the exact original part specification, the P0720ECMCAP remains available in limited inventory.

Frequently Asked Questions (FAQ)

Q: Can the P0720ECMCLAP be used as a direct replacement for the P0720ECMCAP?

A: Yes. Both parts are electrically and mechanically identical, with all voltage, current, and capacitance parameters matching exactly. The primary differences are product status and RoHS compliance.

Q: What is the difference between the packaging options?

A: The P0720ECMCAP is supplied in bulk packaging, while the P0720ECMCLAP is supplied in Tape & Box (TB) format. Both use the same TO-226-2 or TO-92-2 package form factor for through-hole mounting.

Q: Why is the P0720ECMCAP listed as obsolete?

A: Obsolete status indicates the manufacturer has discontinued active production. The P0720ECMCLAP, as an active product, represents the current manufacturing equivalent.

Q: Are there RoHS compliance implications for substitution?

A: The P0720ECMCAP is RoHS non-compliant, while the P0720ECMCLAP is ROHS3 compliant. For applications subject to RoHS regulations, the P0720ECMCLAP is the required selection.

Q: Do both parts have the same moisture sensitivity level?

A: Yes. Both the P0720ECMCAP and P0720ECMCLAP have MSL 1 (Unlimited), indicating no moisture sensitivity restrictions.
