Substitute Part Grouping Explanation

Substitution eligibility is determined by the following criteria:

Primary Compatibility Requirements:

Capacitance value: 0.047 µF (exact match required)
Lead spacing: 0.100" (2.54mm) (exact match required)
Mounting type: Through Hole (exact match required)
Package type: Radial (exact match required)

Allowable Parameter Variations:

Voltage rating: Equal to or greater than 50V
Tolerance: Equal to or tighter than ±20%
Temperature coefficient: Z5U or X7R (X7R provides wider operating range: -55°C ~ 125°C vs. 10°C ~ 85°C)

Frequently Asked Questions (FAQ)

Q: Can I use a substitute part with higher voltage rating? A: Yes. Higher voltage ratings provide additional safety margin and are electrically compatible. The 1C10X7R473K100B (100V) and C315C473KAR5TA (250V) are direct substitutes for the 50V rated 1C10Z5U473M050B in applications where voltage headroom is beneficial.

Q: What is the difference between Z5U and X7R temperature coefficients? A: Z5U provides ±20% capacitance change over 10°C ~ 85°C operating range. X7R provides ±15% capacitance change over -55°C ~ 125°C operating range. X7R offers wider temperature stability and extended operating range, making it suitable for industrial and automotive applications.

Q: Are KEMET C320C and C315C series parts mechanically compatible? A: Both series maintain 0.100" lead spacing and radial through-hole mounting. C320C parts have maximum height of 0.290" compared to the original 0.250". C315C parts are more compact at 0.183" height. PCB layout must accommodate these dimensional differences.

Q: What tolerance improvement does C320C473J5R5TA offer? A: This part provides ±5% tolerance compared to the original ±20%, representing a four-fold improvement in capacitance accuracy. Combined with X7R coefficient, it is suitable for precision analog circuits requiring tight capacitance values.

Q: Can I substitute the 1C10Z5U473M050B with a part from a different manufacturer? A: Yes. KEMET C320C473M5U5TA and C315C473M5U5TA are electrically and mechanically equivalent. Both maintain identical capacitance, voltage, tolerance, and temperature coefficient specifications. Physical dimensions vary slightly and must be verified against PCB layout constraints.

Q: Which substitute offers the best overall performance upgrade? A: The 1C10X7R473K050B from Vishay provides the optimal upgrade path, maintaining identical physical dimensions while improving tolerance to ±10% and extending operating temperature range to -55°C ~ 125°C. Inventory availability is also highest at 10,710 units.
