Substitute Part Grouping Explanation

Substitute parts for the 475KXM050M are classified into three categories based on substitution logic:

Parametric Equivalent Parts maintain identical electrical and mechanical specifications: 4.7 µF capacitance, ±20% tolerance, 50 V rated voltage, 2000-hour lifetime at 105°C, -55°C to 105°C operating temperature, 0.079" lead spacing, 0.197" diameter, and 0.492" maximum seated height. These parts are direct functional replacements with no design modifications required.

Direct Manufacturer Equivalent Parts share the same capacitance, tolerance, voltage rating, lifetime, operating temperature range, lead spacing, and package dimensions as the main part, but originate from different manufacturers. These parts are functionally interchangeable within the same electrical and mechanical constraints.

Upgrade Parts provide enhanced performance through higher voltage ratings (63 V, 80 V, 100 V) or extended lifetime specifications (5000 hours at 105°C) while maintaining identical capacitance, tolerance, lead spacing, and physical dimensions. These parts are suitable for applications requiring improved voltage margin or extended operational life.

The critical parameters determining substitution eligibility are: capacitance value (4.7 µF), tolerance (±20%), operating temperature range (-55°C to 105°C), lead spacing (0.079" / 2.00mm), case diameter (0.197" / 5.00mm), maximum seated height (0.492" / 12.50mm), mounting type (Through Hole), and package style (Radial, Can).

Engineering Selection Recommendations

For Direct Replacement (Same Electrical and Mechanical Specifications):

UPJ1H4R7MDD, UPM1H4R7MDD, and UPS1H4R7MDD are parametric equivalents to the 475KXM050M. All three parts maintain 4.7 µF capacitance, 50 V voltage rating, ±20% tolerance, 2000-hour lifetime at 105°C, identical lead spacing, and package dimensions. These parts are suitable for applications where the original specification must be preserved without modification. UPM1H4R7MDD carries AEC-Q200 automotive qualification, making it appropriate for automotive-grade applications.

For Extended Lifetime Applications:

UPV1H4R7MFD provides a 5000-hour lifetime at 105°C while maintaining all other electrical and mechanical parameters identical to the main part. This upgrade is applicable to designs requiring extended operational life without voltage margin increase.

For Increased Voltage Margin:

UPS1J4R7MDD (63 V), UPM1K4R7MDD (80 V), and UPS2A4R7MDD (100 V) are upgrade options providing higher voltage ratings. These parts maintain 4.7 µF capacitance, ±20% tolerance, 2000-hour lifetime at 105°C, and identical physical dimensions. UPM1K4R7MDD includes AEC-Q200 automotive qualification. Selection depends on circuit voltage requirements and design margin specifications.

All substitute parts listed are ROHS3 compliant and REACH unaffected, matching the regulatory status of the main part. All parts maintain Through Hole mounting type and Radial, Can package configuration.
