Key Parameters

Substitute Part Grouping Explanation

Substitution of the P0640SDRP is determined by strict equivalence across the following electrical and mechanical parameters:

• Voltage - Breakover: 77 V
• Voltage - Off State: 58 V
• Voltage - On State: 4 V
• Current - Peak Pulse (8/20µs): 1 kA
• Current - Peak Pulse (10/1000µs): 200 A
• Current - Hold (Ih): 50 mA
• Capacitance: 160 pF
• Number of Elements: 1
• Package / Case: DO-214AA, SMB
• Mounting Type: Surface Mount

The P0640SDLRP meets all electrical specifications and mechanical requirements. The primary difference is packaging format (Tape & Reel versus cut tape) and product status (Active versus Obsolete).

Parameter Comparison

Engineering Selection Recommendations

The P0640SDLRP is the direct functional equivalent of the P0640SDRP. All electrical parameters and mechanical specifications are identical. Selection of the P0640SDLRP is supported by the following factors:

• Active product status ensures ongoing manufacturer support and availability
• ROHS3 compliance meets current environmental and regulatory requirements
• Identical electrical performance across all specified parameters
• Compatible footprint and mounting type for direct PCB substitution
• Tape & Reel packaging is standard for production volume applications

The P0640SDLRP is suitable for direct replacement in all applications where the P0640SDRP was originally specified.

Frequently Asked Questions (FAQ)

Q: Can the P0640SDLRP be used as a direct replacement for the P0640SDRP?

A: Yes. All electrical parameters, mechanical specifications, and package dimensions are identical. The components are functionally equivalent and pin-compatible.

Q: What is the difference between the P0640SDRP and P0640SDLRP?

A: The primary differences are product status (Obsolete versus Active), RoHS compliance level (non-compliant versus ROHS3 Compliant), and packaging format (cut tape versus Tape & Reel). Electrical and mechanical specifications are identical.

Q: Does the Tape & Reel packaging of the P0640SDLRP affect PCB assembly?

A: No. Tape & Reel is a standard packaging format for automated pick-and-place assembly. The component itself is identical to cut tape versions. Assembly equipment compatibility depends on your production line configuration, not the component.

Q: Are there any circuit design changes required when substituting the P0640SDLRP with the P0640SDLRP?

A: No. Identical electrical parameters eliminate the need for circuit redesign. The component can be substituted without modification to schematic, PCB layout, or bill of materials specifications.

Q: What is the inventory status of the P0640SDLRP?

A: The P0640SDLRP is obsolete with limited stock availability. The P0640SDLRP is an active product with 32,785 units in stock, ensuring reliable supply for current and future production requirements.
