Key Parameters

Substitute Part Grouping Explanation

Substitution of the P0640EARP1 is determined by electrical and mechanical parameter equivalence. The substitute part P0640EALRP1 maintains identical electrical specifications across all critical parameters: breakover voltage (77V), off-state voltage (58V), on-state voltage (4V), peak pulse currents (150A at 8/20µs and 45A at 10/1000µs), hold current (150mA), and capacitance (60pF). Both parts share the same package configuration (TO-226-2, TO-92-2) and mounting type (through hole), ensuring mechanical and electrical compatibility. The primary distinction is packaging format and product status.

Parameter Comparison

Engineering Selection Recommendations

The P0640EALRP1 is the direct equivalent for the obsolete P0640EARP1. Both parts are manufactured by Littelfuse Inc. and maintain identical electrical and mechanical specifications. The P0640EALRP1 offers the advantage of active product status, ensuring continued availability and manufacturing support. Additionally, the P0640EALRP1 is ROHS3 compliant, whereas the P0640EARP1 is RoHS non-compliant. For new designs or ongoing procurement, the P0640EALRP1 is the appropriate selection. The primary operational difference is packaging format: P0640EARP1 is supplied in tube packaging, while P0640EALRP1 is supplied in tape and reel format, which may affect procurement quantities and handling procedures.

Frequently Asked Questions (FAQ)

Q: Can P0640EALRP1 be used as a direct replacement for P0640EARP1? A: Yes. Both parts are electrically and mechanically identical, with identical voltage ratings (77V breakover, 58V off-state, 4V on-state), current ratings (150A peak pulse at 8/20µs, 45A at 10/1000µs), and package configuration (TO-226-2, TO-92-2 through-hole). The P0640EALRP1 is the active equivalent.

Q: What is the difference between P0640EARP1 and P0640EALRP1? A: The parts are electrically identical. The differences are: (1) Product status—P0640EARP1 is obsolete while P0640EALRP1 is active; (2) Packaging format—P0640EARP1 is tube packaged while P0640EALRP1 is tape and reel; (3) RoHS compliance—P0640EARP1 is RoHS non-compliant while P0640EALRP1 is ROHS3 compliant.

Q: Are there any electrical performance differences between these parts? A: No. Both parts have identical electrical specifications: 77V breakover voltage, 58V off-state voltage, 4V on-state voltage, 150A peak pulse current (8/20µs), 45A peak pulse current (10/1000µs), 150mA hold current, and 60pF capacitance.

Q: Does packaging format affect circuit performance? A: No. Packaging format (tube versus tape and reel) affects only procurement, handling, and storage procedures. Electrical and mechanical performance are identical.

Q: Is the P0640EALRP1 suitable for RoHS-compliant applications? A: Yes. The P0640EALRP1 is ROHS3 compliant, making it suitable for applications requiring RoHS compliance. The P0640EARP1 is RoHS non-compliant.
