Substitute Part Grouping Explanation

Substitution eligibility for the MF-R075-AP-17 is determined by strict equivalence across all critical electrical and mechanical parameters. The following parameters must match identically for a part to function as a direct substitute:

Electrical Parameters (Must Match Exactly):

  • Voltage - Maximum: 60V
  • Current - Hold (Ih) Maximum: 750 mA
  • Current - Trip (It): 1.5 A
  • Current - Maximum: 40 A
  • Time to Trip: 6.3 s
  • Resistance - Initial (Ri) Minimum: 180 mOhms
  • Resistance - Post Trip (R1) Maximum: 600 mOhms
  • Operating Temperature Range: -40°C to 85°C

Mechanical Parameters (Must Match Exactly):

  • Mounting Type: Through Hole
  • Package / Case: Radial, Disc
  • Diameter: 10.40 mm
  • Thickness: 3.10 mm
  • Height - Seated Maximum: 16.00 mm
  • Lead Spacing: 5.10 mm

Compliance Parameters:

  • RoHS3 Compliant
  • Moisture Sensitivity Level: 1 (Unlimited)

The primary distinction between the main part and its substitute relates to packaging format (Tape & Box versus Cut Tape) and approval agency certifications. These differences do not affect electrical or mechanical performance in circuit applications.
