i.e… ±20%(M) tolerance part can replace +80%/-20%(Z) tolerance part
»Voltage Ratings (VDC or VAC) :
Substitution Rule: A component with a higher voltage rating may be used
in place of,
or as a substitute for, a lower voltage rated component
i.e… 1000V rated part can replace 500V, 250V or 100V rated part
i.e… 500V rated part can replace 250V , 100V or 50V rated part
i.e… 250V rated part can replace 100V, 50V or 25V rated part
i.e… 100V rated part can replace 50V or 25V rated part
i.e… 50V rated part can replace 25V or 16V rated part
i.e… 25V rated part can replace 16V or 10V rated part
i.e… 16V rated part can replace 10V or 6.3V rated part
i.e… 10V rated part can replace 6.3V or 4V rated part
»Component Size: (Radial Leaded Styles)
Substitution Rule: In many cases a smaller size component may be acceptable...if lead spacing is same (see page 1) and electrical specifications
differences are
acceptable
(see this page)
i.e... a smaller diameter size taped part could be considered to replace a larger diameter size
taped part
i.e... 5mm, 7mm or 9mm height size could be considered to replace a larger 7, 9 or 11mm
height size
i.e... 10mm diameter size could be considered to replace a 12mm diameter size
(same LS = 5.0mm)
»Temperature Rating : (Electrolytic Capacitors)
Substitution Rule: A component with a higher (better) temperature rating
can replace a lower temperature rated component.
i.e...an +125°C rated part can replace a +105°C or +85°C part (NACT replaces NACEW /
NACZ / NACE)
i.e...an +105°C rated part can replace a +85°C (NRWA or NRSZ replaces NRSA / NRSS .....
NACEW / NACZ replaces NACE)
»"TC" - Temperature Coefficient : (Ceramic Capacitors)
Substitution Rule: A component with a more stable (better) temperature coefficient (TC) can replace a less temperature stable TC component.
i.e...an X7R ceramic can replace Z5U or Y5V ceramic part
i.e...an NPO ceramic can replace a X7R or Z5U or Y5V ceramic
»"DF" - Dissipation Factor :
Substitution Rule: A component with a lower DF (%) can replace a higher DF (%) component.
i.e... NPO part can replace X7R or Z5U / Y5V part
i.e... X7R part can replace Z5U / Y5V part
i.e... NACZ series can replace NACE
i.e... NRSA series can replace NRSS
Substitution Rule: A component with a lower ESR or Z (ohm) can replace a higher ESR or Z (ohm) component.
i.e... NTP series part can replace NTC series part
i.e... NACZ & NACZF series can replace NACEW or NACE
i.e... NRSX series can replace NRSZ or NRSY
»Ripple Current
Rating (mA):
Substitution Rule: A component with a higher ripple current rating (mArms)
can replace a lower ripple current rated component.
i.e... NTP series part can replace NTC series part
i.e... NACZ & NACZF series can replace NACEW or NACE
i.e... NRSX series can replace NRSZ or NRSY
»Leakage Current
Rating (uA): (Electrolytic Capacitors)
Substitution Rule: A component with a lower leakage current rating (uA)
can replace a higher leakage current rated component.
i.e... NACL series part can replace NACE series part
i.e... NLE-L series can replace NRSA or NRSS
»"IR"
- Insulation Resistance (ohm or meg-ohm):
(Electrostatic Capacitors)
Substitution Rule: A component with a higher insulation resistance
(ohm or meg-ohm) can replace a lower insulation resistance rated component.
i.e... NPO series part can replace X7R/ Y5V/Z5U part
i.e... X7R series part can replace Y5V/Z5U part
