Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LR1F620K is determined by strict equivalence across the following critical parameters:

Electrical Parameters (Must Match Exactly):

• Resistance value: 620 kOhms
• Tolerance: ±1%
• Power rating: 0.6W
• Temperature coefficient: ±50ppm/°C
• Operating temperature range: -55°C to 155°C

Mechanical Parameters (Must Match Exactly):

• Package type: Axial
• Number of terminations: 2
• Composition: Metal Film

Compliance Parameters (Must Match Exactly):

• RoHS Status: ROHS3 Compliant
• REACH Status: REACH Unaffected

The substitute part MRS25000C6203FCT00 manufactured by Vishay Beyschlag/Draloric/BC Components meets all electrical, mechanical, and compliance requirements for direct substitution. Physical dimensions vary slightly (0.098" Dia x 0.256" L versus 0.091" Dia x 0.244" L), which is acceptable within standard axial resistor tolerance ranges for through-hole mounting applications.
