Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 860040775009 are identified based on the following critical parameters:

• Capacitance Value: 180 µF (exact match required)
• Voltage Rating: 63 V minimum (equal or higher voltage rating acceptable)
• Polarization: Polar (electrolytic type)
• Package Configuration: Radial, Can (through-hole)
• Lead Spacing: 0.197" (5.00 mm)
• Physical Dimensions: 0.394" diameter, compatible height range
• Operating Temperature Range: -40°C ~ 105°C minimum

Two substitute parts meet these criteria with variations in lifetime rating and voltage specification. Substitution is valid when the replacement part maintains or exceeds the electrical performance requirements of the original design.

Parameter Comparison

Engineering Selection Recommendations

EEU-FR1J181B (Panasonic Electronic Components)

This substitute maintains the 63 V voltage rating and 180 µF capacitance specification. The part is Active status and ROHS3 compliant. The extended lifetime rating of 10000 hours at 105°C provides improved reliability compared to the original 7000-hour specification. Lower impedance (35 mOhms versus 190 mOhms) and higher ripple current capability support applications with increased AC stress. Physical dimensions are compatible with a maximum seated height of 0.866 inches, representing a 0.020-inch increase from the original specification.

UHW1K181MPD1TD (Nichicon)

This substitute provides a higher voltage rating of 80 V while maintaining the 180 µF capacitance and ±20% tolerance. The part carries a "Not For New Designs" status, indicating it is suitable for replacement and maintenance applications only. ROHS3 compliance is maintained. The 10000-hour lifetime at 105°C exceeds the original specification. The elevated voltage rating provides additional design margin for circuits operating near the 63 V nominal specification. Physical dimensions are compatible with a maximum seated height of 0.866 inches.

Frequently Asked Questions (FAQ)

Q: Can EEU-FR1J181B be used as a direct replacement for 860040775009?

A: Yes. Both parts share identical capacitance (180 µF), voltage rating (63 V), tolerance (±20%), polarization (polar), package type (radial can), lead spacing (5.00 mm), and physical diameter (10.00 mm). The seated height difference of 0.020 inches is within typical PCB layout tolerances for through-hole components.

Q: What is the advantage of using EEU-FR1J181B over the original part?

A: The Panasonic substitute offers extended lifetime (10000 hours versus 7000 hours at 105°C), significantly lower impedance (35 mOhms versus 190 mOhms), and higher ripple current ratings at both low and high frequencies. These characteristics improve performance in applications with elevated AC ripple or thermal stress.

Q: Can UHW1K181MPD1TD be used in place of 860040775009?

A: Yes, with consideration of product status. The Nichicon part maintains the 180 µF capacitance, ±20% tolerance, polar configuration, and through-hole package. The 80 V rating exceeds the 63 V requirement, providing additional voltage margin. However, the "Not For New Designs" status restricts this part to replacement and maintenance applications only.

Q: Why does UHW1K181MPD1TD have a higher voltage rating?

A: The 80 V rating is a distinct specification for this part series. Higher voltage ratings do not negatively impact circuits designed for lower voltages; the capacitor simply provides additional electrical margin. This substitution is valid for designs operating at or below 63 V.

Q: Are there any physical installation differences between these parts?

A: All three parts use identical lead spacing (5.00 mm) and diameter (10.00 mm). The seated heights are 0.846 inches (original), 0.866 inches (Panasonic), and 0.866 inches (Nichicon). The maximum 0.020-inch height difference is negligible for standard through-hole PCB layouts and does not require design modification.

Q: Do all substitute parts meet RoHS compliance?

A: Yes. The original part (860040775009) and both substitutes (EEU-FR1J181B and UHW1K181MPD1TD) are ROHS3 compliant, meeting environmental and regulatory requirements for electronic component manufacturing and assembly.
