Characteristics Substitution Guide: Resistors |

Resistance Value (ohm): |
 Substitution Rule:
CASE 1: Standard Values E24 & E96: In most cases you cannot change to different resistance value
CASE 2: Non-Standard Values: Offer closest standard E24 & E96 values
|

Resistance Tolerance (%): |
Substitution Rule: A component with a tighter (better) tolerance can replace a looser tolerance component
i.e... ±1%(F) tolerance part can replace ±2%(G), ±5%(J) or ±10% (K) tolerance part
i.e... ±5%(J) tolerance part can replace ± 10%(K) tolerance part |

Power Rating (Watt) |
Substitution Rule: A component with a higher power rating can replace a lower power rated component
i.e... 1/16W rating can replace 1/32W rating
i.e... 1/8W rating can replace 1/16W & 1/32W ratings
i.e... 1/4W rating can replace 1/8W, 1/16W & 1/32W ratings
i.e... 1/2W rating can replace 1/4W, 1/8W, 1/16W & 1/32W ratings
i.e... 1W rating can replace 1/2W, 1/4W, 1/8W, 1/16W & 1/32W ratings |

"TCR" - Temperature
Coefficient of Resistance Value |
Substitution Rule: A component with better (tighter) TCR can replace a component with broader (wider) TCR
i.e... +/-50PPM TCR can replace +/-100PPM, +/-200PPM and +/-350PPM TCR
i.e... +/-100PPM TCR can replace +/-200PPM and +/-350PPM TCR
i.e... +/-200PPM TCR can replace +/-350PPM TCR |

Component Size (D x L): Axial Leaded Styles |
Substitution Rule: A smaller size component, with comparable ratings, can replace a larger size component
i.e... NCF25R can replace NCF25
i.e... NCF50R can replace NCF50
i.e... NMO100S can replace NMO100
i.e... NMO200S can replace NMO200
i.e... NMO300S can replace NMO300 |
