Substitute Part Grouping Explanation

The 0473.375MAT1L qualifies as a parametric equivalent to the 0473.375PARL based on identical electrical and mechanical specifications. Substitution is valid across the following critical parameters:

  • Current Rating: 375 mA (identical)
  • Voltage Rating: 125 V AC / 125 V DC (identical)
  • Response Time: Slow Blow (identical)
  • Mounting Type: Through Hole (identical)
  • Package / Case: Axial (identical)
  • Breaking Capacity: 50 A (identical)
  • Melting I²t: 0.085 (identical)
  • Operating Temperature: -55°C ~ 125°C (identical)
  • Physical Dimensions: 0.135" Dia x 0.280" L (identical)
  • DC Cold Resistance: 1.74 Ohms (identical)
  • Compliance: RoHS3, CSA/UR approvals (identical)

The sole difference between these parts is packaging format: the main part uses Tape & Box (TB) packaging, while the substitute uses Cut Tape (CT) packaging. Both parts belong to the PICO® II 473 series and maintain Active product status.

Engineering Selection Recommendations

Both the 0473.375PARL and 0473.375MAT1L are suitable for direct substitution in applications requiring a 375 mA, 125 V AC/DC axial fuse with slow blow response. Selection between these parts should be based on procurement and assembly requirements:

The 0473.375PARL in Tape & Box packaging is appropriate for standard board-level assembly operations where bulk quantities and organized packaging facilitate handling and placement.

The 0473.375MAT1L in Cut Tape packaging is appropriate for automated pick-and-place assembly processes or applications requiring smaller order quantities with reduced packaging overhead.

Both parts carry identical electrical performance, thermal ratings, and regulatory approvals (RoHS3, CSA, UR). No functional differences exist between these components.

Frequently Asked Questions (FAQ)

Q: Can 0473.375MAT1L replace 0473.375PARL in production?

A: Yes. Both parts are electrically and mechanically identical. The only difference is packaging format (Tape & Box versus Cut Tape). Selection depends on assembly process requirements and supply chain logistics.

Q: Are there any electrical performance differences between these fuses?

A: No. Both parts share identical current rating (375 mA), voltage rating (125 V AC/DC), response time (Slow Blow), breaking capacity (50 A), melting I²t (0.085), and DC cold resistance (1.74 Ohms).

Q: Do both parts meet the same regulatory standards?

A: Yes. Both 0473.375PARL and 0473.375MAT1L are RoHS3 compliant and carry CSA and UR approvals.

Q: What is the physical difference between Tape & Box and Cut Tape packaging?

A: Tape & Box packaging provides organized spooled components in a protective box, suitable for standard assembly operations. Cut Tape packaging provides individual components cut from tape, suitable for automated pick-and-place systems or lower-volume applications.

Q: Can these fuses be used interchangeably in the same circuit design?

A: Yes. The identical electrical specifications, thermal characteristics, and physical dimensions ensure direct functional equivalence in any circuit application.
