Substitute Part Grouping Explanation

Substitute parts for the ECO-S2DP182EX are classified based on electrical and mechanical compatibility within the following criteria:

Direct Substitutes maintain identical electrical specifications (1800 µF, 200 V, ±20% tolerance) and mechanical footprint (35mm diameter, 10mm lead spacing, snap-in package). These parts are interchangeable without circuit redesign.

Upgrade Substitutes provide enhanced performance characteristics, such as extended operating temperature ranges or improved lifetime ratings, while maintaining core electrical parameters and mechanical compatibility.

Similar Substitutes share the same capacitance, voltage, and tolerance values with minor variations in height or ESR specifications that may require mechanical verification but remain electrically compatible.

Parametric Equivalents match all critical electrical parameters and physical dimensions, ensuring functional equivalence in the application circuit.

The following parameters determine substitution eligibility:

Capacitance: 1800 µF (fixed)
Voltage Rating: 200 V (fixed)
Tolerance: ±20% (fixed)
Package: Radial, Can - Snap-In (fixed)
Lead Spacing: 0.394" (10.00mm) (fixed)
Diameter: 1.378" (35.00mm) (fixed)

Engineering Selection Recommendations

For Direct Replacement with Minimal Mechanical Variation: Select 200USG1800MEFCSN35X35 (Rubycon USG series). This part maintains active product status, ROHS3 compliance, and identical electrical specifications with 3000-hour lifetime at 85°C. Height reduction from 1.575" to 1.457" requires PCB layout verification but does not affect electrical function.

For Extended Temperature Operation: Select LGW2D182MELC40 (Nichicon LGW series). This upgrade substitute extends operating temperature to 105°C and maintains 3000-hour lifetime at the elevated temperature. Physical dimensions match the original part (1.575" height), and ROHS3 compliance is confirmed.

For Reduced Height Constraint Applications: Select 200USG1800MEFC35X35 (Rubycon USG series). This part offers the lowest profile at 1.457" height while maintaining electrical equivalence. Note RoHS non-compliance status for applications requiring regulatory compliance.

For Consistent ESR Performance: Select 380LQ182M200A032 (Cornell Dubilier 380LQ series) or 380LX182M200A452 (Cornell Dubilier 380LX series). Both maintain ESR specifications comparable to the original part. The 380LQ series provides 2000-hour lifetime, while 380LX extends to 3000 hours with slightly lower ESR (111mOhm vs. 120mOhm).

For Maximum Availability and Compliance: Select LLS2D182MELC (Nichicon LLS series). This parametric equivalent offers the highest inventory level (273,982 pcs), ROHS3 compliance, and matching physical dimensions with 3000-hour lifetime at 85°C.

Frequently Asked Questions (FAQ)

Q: Can I use a substitute part with a different height? A: Height variation is acceptable if PCB layout accommodates the dimensional change. Parts with reduced height (37.00mm vs. 40.00mm) require clearance verification. Parts with increased height (45.00mm or 47.00mm) require mechanical space confirmation. Electrical function remains unchanged.

Q: What is the difference between ROHS3 compliant and RoHS non-compliant parts? A: ROHS3 compliance indicates the part meets Restriction of Hazardous Substances Directive requirements. RoHS non-compliant parts may contain restricted substances and are subject to regulatory limitations in certain markets. Select ROHS3 compliant alternatives for applications requiring regulatory compliance.

Q: Does ESR variation affect circuit performance? A: ESR (Equivalent Series Resistance) affects ripple current handling and thermal performance. The original part specifies 120mOhm at 120Hz. Substitute parts with 111mOhm ESR provide improved ripple current performance. Parts without specified ESR values require datasheet consultation for ripple current ratings.

Q: Can I substitute a part with lower lifetime rating? A: The original part specifies 3000 hours at 85°C. LPX182M200H4P3 provides only 1000 hours at 85°C and is suitable only for applications with reduced operational duration requirements. For equivalent or extended lifetime, select parts rated 3000 hours or higher.

Q: Are all substitute parts mechanically interchangeable? A: All substitute parts maintain the same lead spacing (10.00mm) and diameter (35.00mm), ensuring PCB footprint compatibility. Height variations require mechanical clearance verification. Snap-in package design is consistent across all listed parts.

Q: Which substitute offers the best overall compatibility? A: 200USG1800MEFCSN35X35 (Rubycon) and LLS2D182MELC (Nichicon) provide the closest electrical and mechanical match with active product status and ROHS3 compliance. Both maintain 3000-hour lifetime at 85°C and standard physical dimensions.
