Substitute Part Grouping Explanation

Substitution of the P0720EARP2 is determined by matching the following critical electrical and mechanical parameters:

• Voltage - Off State: 65V
• Voltage - Breakover: 88V
• Voltage - On State: 4V
• Current - Peak Pulse (8/20µs): 150A
• Current - Peak Pulse (10/1000µs): 45A
• Current - Hold (Ih): 150mA
• Capacitance: 60pF
• Number of Elements: 1
• Package / Case: TO-226-2, TO-92-2 (TO-226AC)
• Mounting Type: Through Hole

The P0720EALRP2 meets all specified electrical and mechanical parameters. The primary distinction is packaging format and product status.

Engineering Selection Recommendations

The P0720EALRP2 is the direct functional equivalent of the P0720EARP2. Both parts share identical electrical specifications and package configurations. Selection between these parts should be based on the following factors:

Product Status: The P0720EARP2 is obsolete. The P0720EALRP2 is active and represents the current production equivalent.

RoHS Compliance: The P0720EALRP2 is ROHS3 compliant, whereas the P0720EARP2 is non-compliant. Applications subject to RoHS requirements must use the P0720EALRP2.

Packaging Format: The P0720EARP2 is supplied in tube packaging. The P0720EALRP2 is supplied in Tape & Reel format, which is standard for automated assembly processes.

Availability: The P0720EALRP2 has higher inventory availability (4400 pcs) compared to the P0720EARP2 (1062 pcs).

Frequently Asked Questions (FAQ)

Q: Can the P0720EALRP2 replace the P0720EARP2 in existing designs?

A: Yes. Both parts are electrically and mechanically identical. The P0720EALRP2 is the active production equivalent and can be used as a direct replacement.

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

A: The primary differences are product status (obsolete vs. active), packaging format (tube vs. Tape & Reel), and RoHS compliance status. Electrical specifications and package configurations are identical.

Q: Are there any compatibility concerns when switching from P0720EARP2 to P0720EALRP2?

A: No compatibility concerns exist for circuit operation. Both parts have identical electrical parameters and package dimensions. Procurement and assembly processes may differ due to packaging format differences.

Q: Is the P0720EALRP2 suitable for RoHS-compliant applications?

A: Yes. The P0720EALRP2 is ROHS3 compliant and meets RoHS requirements. The P0720EARP2 is not RoHS compliant.

Q: What packaging format should be selected for automated assembly?

A: The P0720EALRP2 in Tape & Reel format is standard for automated assembly processes. The P0720EARP2 in tube packaging is suitable for manual assembly or lower-volume applications.
