Substitute Part Grouping Explanation

Substitute parts for the ECO-S1KP182CA are classified based on strict electrical and mechanical parameter alignment. The primary substitution criteria are:

Critical Parameters (Must Match):

Capacitance: 1800 µF
Voltage Rating: 80 V
Tolerance: ±20%
Lead Spacing: 0.394" (10.00 mm)
Package Type: Radial, Can - Snap-In
Mounting Type: Through Hole
Polarization: Polar

Secondary Parameters (Allowable Variation):

ESR: Equivalent or lower values acceptable
Lifetime @ Temperature: Equal or greater duration acceptable
Operating Temperature Range: Must support minimum -40°C to 85°C
Physical Dimensions: Minor variations acceptable within snap-in package constraints

Direct Substitutes maintain all critical parameters with matching or superior electrical performance. Similar Substitutes meet all critical parameters but may have minor dimensional or thermal rating differences that do not affect functional compatibility in the application.

Engineering Selection Recommendations

Direct Substitutes (Preferred):

The 380LX182M080J022 from Cornell Dubilier Electronics is the primary direct substitute. It maintains identical electrical specifications (1800 µF, 80 V, ±20%, 147 mOhm ESR, 3000 Hrs @ 85°C) with active product status and ROHS3 compliance. Height variation of 0.079" (2.00 mm) is within snap-in package tolerance. This part is recommended for applications where ESR performance and thermal lifetime matching are critical.

The B41231B0188M000 from EPCOS - TDK Electronics provides an alternative with active status and ROHS3 compliance. While lifetime specification is reduced to 2000 hours at 85°C, physical dimensions are more compact. This part is suitable for applications where space constraints exist and reduced thermal lifetime is acceptable.

Similar Substitutes (Conditional):

The 380LX182M080H032, SLP182M080C3P3, SLPX182M080A3P3, and SLPX182M080C1P3 all meet critical electrical parameters with active product status and ROHS3 compliance. These parts feature slightly elevated ESR values (184 mOhm) and dimensional variations. The SLP182M080C3P3 extends operating temperature to 105°C, providing enhanced thermal margin. Selection among these parts depends on specific PCB layout constraints and thermal environment requirements.

All substitute parts maintain the 0.394" (10.00 mm) lead spacing and radial snap-in package configuration, ensuring mechanical compatibility with the original ECO-S1KP182CA footprint.

Frequently Asked Questions (FAQ)

Q: Can I use a substitute part with higher ESR than the original ECO-S1KP182CA?

A: Yes. The substitute parts with 184 mOhm ESR (SLP182M080C3P3, SLPX182M080A3P3, SLPX182M080C1P3) are acceptable. Higher ESR values increase power dissipation and heat generation but remain within acceptable limits for general-purpose applications. Verify thermal conditions in your specific application.

Q: What is the significance of the different physical dimensions among substitute parts?

A: All substitute parts maintain the 0.394" (10.00 mm) lead spacing and radial snap-in package type, ensuring PCB footprint compatibility. Height and diameter variations reflect different internal construction but do not affect electrical function. Verify clearance in your specific PCB layout, particularly for parts with greater height (380LX182M080H032 at 1.457" maximum height).

Q: Are all substitute parts RoHS compliant?

A: Yes. All listed substitute parts carry ROHS3 compliance certification. The original ECO-S1KP182CA does not specify RoHS status due to its obsolete classification.

Q: Which substitute part should I select if thermal performance is critical?

A: The SLP182M080C3P3 offers the widest operating temperature range (-40°C to 105°C) and maintains 3000-hour lifetime at 85°C. The 380LX182M080J022 provides matching ESR and lifetime specifications to the original part. Both are suitable for thermally demanding applications.

Q: Can I interchange substitute parts within the same design?

A: All listed substitute parts are mechanically and electrically compatible for the ECO-S1KP182CA application. However, verify ESR and thermal lifetime specifications against your circuit requirements before final selection. Parts with identical ESR (147 mOhm) provide closest performance matching.

Q: What is the inventory status of these substitute parts?

A: All substitute parts are listed as active products with current inventory availability ranging from 713 to 1069 pieces, ensuring reliable procurement compared to the obsolete ECO-S1KP182CA.
