Engineering Selection Recommendations

Direct Substitutes (80 V Rating):

The following parts are direct substitutes for the ECO-S1KP272DA and maintain the original 80 V voltage specification:

SLP272M080E3P3 (Cornell Dubilier Electronics): Active product with matching capacitance, tolerance, and voltage. Offers extended operating temperature range (-40°C to 105°C) and extended lifetime (3000 Hrs @ 105°C). Physical dimensions match the original part.
380LX272M080J032 (Cornell Dubilier Electronics): Active product with matching electrical specifications and ESR characteristics. Maintains 3000-hour lifetime at 85°C. Height of 1.457" (37.00 mm) requires verification against mechanical envelope constraints.
380LX272M080H452 (Cornell Dubilier Electronics): Active product with identical ESR and lifetime ratings. Height of 1.850" (47.00 mm) requires mechanical clearance verification.
80MXG2700MEFCSN30X25 (Rubycon): Active product with extended operating temperature range and 3000-hour lifetime at 105°C. Compact height of 1.063" (27.00 mm) provides space advantage.

Frequently Asked Questions (FAQ)

Q: Can I use a 100 V or 160 V rated capacitor in place of the 80 V ECO-S1KP272DA?

A: Yes. Higher voltage-rated capacitors are electrically compatible with circuits designed for 80 V operation. The capacitor will operate safely at voltages below its rated maximum. Verify that the physical dimensions (particularly height) fit within the available mechanical envelope.

Q: What is the significance of ESR (Equivalent Series Resistance)?

A: ESR affects ripple current handling and heat dissipation. The original ECO-S1KP272DA specifies 98 mOhm @ 120 Hz. Substitute parts with similar or lower ESR values maintain equivalent electrical performance. Parts without specified ESR values are acceptable if other electrical parameters match.

Q: Does operating temperature range affect substitution?

A: The original part operates from -40°C to 85°C. Substitute parts with extended ranges (up to 105°C) are acceptable and provide additional thermal margin. Parts with identical or narrower temperature ranges are also acceptable if the application does not require extended temperature operation.

Q: What is the importance of lifetime rating?

A: Lifetime rating (e.g., 3000 Hrs @ 85°C) indicates the expected operational duration under specified conditions. Substitute parts with equal or extended lifetime ratings maintain or improve reliability. The original part specifies 3000 Hrs @ 85°C; parts with 5000-hour ratings provide extended service life.

Q: Are there mechanical constraints I should consider?

A: Yes. All substitute parts maintain the same lead spacing (0.394" / 10.00 mm) and diameter (1.181" / 30.00 mm), ensuring PCB compatibility. However, seated height varies between 1.063" and 2.441". Verify that the substitute part's height fits within the available vertical clearance in your application.

Q: What does RoHS3 compliance mean?

A: RoHS3 compliance indicates the part meets Restriction of Hazardous Substances regulations. Most active substitute parts are RoHS3 compliant, supporting environmental and regulatory requirements for new designs.

Q: Can I substitute the ECO-S1KP272DA with B41231C0278M000 if lifetime is critical?

A: The B41231C0278M000 has a 2000-hour lifetime at 85°C, compared to the original 3000-hour specification. If your application requires the full 3000-hour lifetime, select an alternative such as SLP272M080E3P3, 80MXG2700MEFCSN30X25, or 80VXG2700MEFC30X35.

Q: What is the difference between "Direct" and "Similar" substitutes?

A: Direct substitutes match the original 80 V voltage rating. Similar substitutes have higher voltage ratings (100 V or 160 V) but maintain the same capacitance and tolerance. Both categories are electrically compatible; voltage selection depends on circuit requirements and available mechanical space.
