Substitute Part Grouping Explanation

Substitute parts for the UPJ2A4R7MED are categorized based on electrical and mechanical parameter alignment:

Direct Equivalents maintain identical or functionally equivalent specifications across all critical parameters: capacitance (4.7 µF), voltage rating (100 V), tolerance (±20%), operating temperature range (-55°C ~ 105°C), polarization (polar), and through-hole mounting. Packaging format differences (bulk versus cut tape) do not affect electrical performance.

Similar Substitutes share the same core electrical specifications (capacitance, voltage, tolerance, temperature range, polarization) but may differ in physical dimensions, lead spacing, impedance, ripple current characteristics, or series designation. These parts are functionally compatible when board layout and thermal management accommodate dimensional variations.

Key Parameters for Substitution Compatibility:

Capacitance: 4.7 µF (exact match required)
Voltage Rating: 100 V (exact match required)
Tolerance: ±20% (exact match required)
Polarization: Polar (exact match required)
Operating Temperature: -55°C ~ 105°C (exact match required)
Mounting Type: Through Hole (exact match required)

Engineering Selection Recommendations

UPJ2A4R7MED1TD is the direct equivalent, differing only in packaging format (cut tape versus bulk). Selection is appropriate when tape-and-reel format is required for automated assembly processes. Product status remains obsolete.

475KXM100M is an active-status substitute from Cornell Dubilier / Illinois Capacitor. It maintains identical lead spacing and case diameter as the original part, ensuring direct board-level compatibility. The increased impedance (8.1 Ohms versus 2.8 Ohms) and ESR (35.27 Ohms @ 120 Hz) must be evaluated against circuit ripple current and thermal management requirements. This part is recommended for new designs requiring long-term component availability.

UPS2A4R7MDD and UPW2A4R7MDD are Nichicon alternatives with reduced physical footprint (0.197" diameter, 2.00mm lead spacing). These parts require PCB layout modification and are suitable only when space constraints justify redesign. Both remain obsolete.

EEU-FC2A4R7 is a Panasonic active-status part with AEC-Q200 automotive qualification. It features reduced physical dimensions (0.197" diameter, 2.00mm lead spacing) and higher ripple current capability (42.25 mA @ 120 Hz). This part is recommended for automotive applications or when active-status components are mandatory. PCB layout modification is required.

Frequently Asked Questions (FAQ)

Q: Can UPJ2A4R7MED1TD be used as a direct replacement? A: Yes. UPJ2A4R7MED1TD is electrically and mechanically identical to UPJ2A4R7MED. The only difference is packaging format (cut tape versus bulk). No circuit or board modifications are required.

Q: What is the primary advantage of 475KXM100M? A: 475KXM100M maintains active product status, ensuring long-term availability and supply chain stability. It preserves the original lead spacing (0.098", 2.50mm) and case diameter (0.248", 6.30mm), allowing direct PCB substitution without layout changes. Higher impedance and ESR values must be verified against circuit performance requirements.

Q: Why do UPS2A4R7MDD and UPW2A4R7MDD have different dimensions? A: These parts belong to different Nichicon series (UPS and UPW) with smaller case designs (0.197" diameter, 2.00mm lead spacing). While electrically equivalent, they require PCB redesign and are not recommended for direct board-level substitution.

Q: Is EEU-FC2A4R7 suitable for non-automotive applications? A: Yes. EEU-FC2A4R7 meets general-purpose application requirements and exceeds automotive standards (AEC-Q200). Its active product status and higher ripple current rating make it suitable for any application requiring the specified electrical parameters. PCB layout modification is necessary due to reduced physical dimensions.

Q: What parameters must remain unchanged during substitution? A: Capacitance (4.7 µF), voltage rating (100 V), tolerance (±20%), polarization (polar), operating temperature range (-55°C ~ 105°C), and mounting type (through hole) must be identical. Lead spacing and case dimensions may vary if PCB layout permits modification.

Q: Are all substitute parts RoHS3 compliant? A: Yes. All listed substitute parts are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.
