Key Parameters

Substitute Part Grouping Explanation

Substitution of the P0300EARP2 is determined by electrical and mechanical parameter equivalence. The critical parameters defining substitutability are:

• Voltage - Off State: 25V
• Voltage - Breakover: 40V
• Voltage - On State: 4V
• Current - Peak Pulse (8/20µs): 150A
• Current - Peak Pulse (10/1000µs): 45A
• Current - Hold (Ih): 50mA
• Capacitance: 140pF
• Package / Case: TO-226-2, TO-92-2 (TO-226AC) (Formed Leads)
• Mounting Type: Through Hole

The P0300EALRP2 meets all electrical specifications and mechanical requirements identical to the main part, with the distinction of different packaging format (Tape & Reel versus bulk) and active product status.

Engineering Selection Recommendations

The P0300EALRP2 is the direct electrical and mechanical equivalent of the P0300EARP2. Selection between these parts should be based on the following factors:

Product Status: The P0300EARP2 is obsolete, while the P0300EALRP2 maintains active product status. For new designs and long-term system support, the P0300EALRP2 is the appropriate choice.

Compliance: The P0300EALRP2 is ROHS3 compliant and REACH unaffected, whereas the P0300EARP2 is RoHS non-compliant. Applications subject to environmental or regulatory compliance requirements should utilize the P0300EALRP2.

Packaging Format: The P0300EARP2 is supplied in bulk packaging, while the P0300EALRP2 is supplied in Tape & Reel format. Packaging selection depends on manufacturing process requirements and order quantities.

Frequently Asked Questions (FAQ)

Q: Can the P0300EALRP2 be used as a direct replacement for the P0300EARP2?

A: Yes. The P0300EALRP2 is electrically and mechanically identical to the P0300EARP2 across all specified parameters, including voltage ratings, current handling, capacitance, and package configuration.

Q: What is the difference between P0300EARP2 and P0300EALRP2?

A: The primary differences are product status (obsolete versus active), RoHS compliance (non-compliant versus ROHS3 compliant), and packaging format (bulk versus Tape & Reel). Electrical and mechanical specifications are identical.

Q: Are there any compatibility concerns when substituting the P0300EALRP2 for the P0300EARP2?

A: No compatibility concerns exist for electrical or mechanical function. Both parts use identical TO-226-2/TO-92-2 through-hole packages and meet the same performance specifications. Packaging format differences do not affect circuit-level compatibility.

Q: Which part should be selected for new designs?

A: The P0300EALRP2 should be selected for new designs due to its active product status and ROHS3 compliance.

Q: Is the Tape & Reel packaging of the P0300EALRP2 compatible with standard pick-and-place equipment?

A: Tape & Reel packaging is standard for automated assembly processes. Compatibility depends on specific equipment specifications and should be verified with manufacturing equipment documentation.
