Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the UPT2P181MHD are qualified based on the following criteria:

Mechanical Compatibility: All substitute parts maintain identical physical dimensions (0.630" diameter, 1.299" height, 7.50 mm lead spacing) and through-hole mounting configuration, ensuring direct PCB footprint compatibility.

Electrical Compatibility: All substitute parts maintain the same capacitance value (180 µF) and tolerance (±20%). Substitute parts operate at rated voltages of 250 V, which exceeds the original 220 V specification, providing voltage margin compatibility for circuits designed around the UPT2P181MHD.

Polarization: All parts are polar aluminum electrolytic capacitors with identical polarity requirements.

Key Differentiators for Substitution:

• Rated voltage: 250 V (substitute) vs. 220 V (original)
• Lifetime: 12000 Hrs @ 105°C (substitute) vs. 5000 Hrs @ 105°C (original)
• Operating temperature range: -40°C ~ 105°C (substitute) vs. -25°C ~ 105°C (original)
• Ripple current ratings: Enhanced in substitute parts
• Manufacturer: Nichicon UCY series or Chemi-Con KXJ series

Parameter Comparison

Engineering Selection Recommendations

Nichicon UCY2E181MHD: This substitute maintains Nichicon manufacturer continuity while providing upgraded performance. The 250 V rating provides 30 V margin above the original 220 V specification. Lifetime is extended to 12000 hours at 105°C, doubling the original 5000-hour rating. Operating temperature range extends to -40°C, providing 15°C additional low-temperature capability. Ripple current capacity is significantly increased. ROHS3 compliance is maintained. This part is suitable for direct replacement in applications requiring enhanced reliability and extended operational life.

Chemi-Con EKXJ251ELL181MLN3S: This substitute provides equivalent electrical performance with AEC-Q200 automotive qualification. The 250 V rating and 12000-hour lifetime match the Nichicon UCY2E181MHD. Operating temperature range is -40°C ~ 105°C. Ripple current ratings are comparable. ROHS3 compliance is maintained. This part is suitable for applications requiring automotive-grade component qualification or multi-source supplier strategies.

Both substitute parts are mechanically and electrically compatible with the UPT2P181MHD and provide enhanced performance characteristics across voltage margin, operational lifetime, and ripple current capacity.

Frequently Asked Questions (FAQ)

Q: Can UCY2E181MHD or EKXJ251ELL181MLN3S be used as direct replacements for UPT2P181MHD?

A: Yes. Both substitute parts maintain identical mechanical dimensions, lead spacing, and mounting configuration. Electrical parameters (capacitance, tolerance, polarization) are identical. The 250 V rating of substitute parts exceeds the 220 V original specification, providing voltage compatibility for circuits designed around the UPT2P181MHD.

Q: What are the key performance differences between the original and substitute parts?

A: The primary differences are rated voltage (220 V original vs. 250 V substitute), operational lifetime (5000 hours vs. 12000 hours at 105°C), operating temperature range (-25°C ~ 105°C vs. -40°C ~ 105°C), and ripple current capacity. Substitute parts provide enhanced performance across all these parameters.

Q: Are there any compliance or certification differences?

A: All three parts are ROHS3 compliant. The Chemi-Con EKXJ251ELL181MLN3S carries AEC-Q200 automotive qualification, while the Nichicon parts do not specify this rating. The Nichicon UCY2E181MHD has REACH Affected status, while the original UPT2P181MHD and Chemi-Con part are REACH Unaffected.

Q: Will the substitute parts fit the same PCB footprint?

A: Yes. All parts share identical physical dimensions (0.630" diameter, 1.299" height) and lead spacing (0.295" / 7.50 mm). Through-hole mounting configuration is identical across all three parts.

Q: Which substitute should be selected for automotive applications?

A: The Chemi-Con EKXJ251ELL181MLN3S is qualified to AEC-Q200 automotive standards and is the appropriate selection for automotive applications.

Q: Can the substitute parts handle higher ripple currents than the original?

A: Yes. Both substitute parts provide significantly higher ripple current ratings. At 120 Hz, the original supports 670 mA while substitutes support 1.11 A (Nichicon) and 955 mA (Chemi-Con). At high frequencies (100 kHz), both substitutes support approximately 2.14-2.22 A compared to the original 1.072 A at 10 kHz.
