Substitute Part Grouping Explanation

Substitute parts for the ECO-S2AP182BA are classified based on strict electrical and mechanical compatibility criteria:

Direct Equivalent (Highest Compatibility): The 380LX182M100H452 from Cornell Dubilier Electronics maintains identical electrical specifications: 1800 µF capacitance, 100 V voltage rating, ±20% tolerance, 3000 hours lifetime at 85°C, and matching mechanical dimensions (0.866" diameter, 10.00 mm lead spacing). ESR is 130 mOhm, within acceptable tolerance of the original 129 mOhm specification. This part is RoHS3 compliant and currently active in production.

Similar Substitutes (Electrical Equivalence with Dimensional Variations): Parts from Rubycon (100MXG1800MEFCSN22X30, 100MXG1800MEFCSN22X40) and Cornell Dubilier (SLP182M100A4P3) maintain the core electrical parameters: 1800 µF, 100 V, ±20% tolerance, and identical lead spacing and case diameter. Height variations range from 1.260" to 1.772", accommodating different PCB layout constraints. These parts feature enhanced temperature ratings (3000 Hrs @ 105°C) and are RoHS3 compliant.

Voltage-Reduced Substitute (Functional Equivalence): The 80MXG1800MEFCSN22X30 from Rubycon provides 1800 µF capacitance at 80 V rating instead of 100 V. This part is suitable only for applications where the actual operating voltage does not exceed 80 V. Mechanical dimensions and lead spacing remain identical.

Alternative with Reduced Lifetime (Conditional Equivalence): The B41231A9188M000 from EPCOS - TDK Electronics matches electrical specifications (1800 µF, 100 V, ±20% tolerance) but specifies 2000 hours lifetime at 85°C versus the original 3000 hours. This part is suitable for applications with less stringent lifetime requirements.

Engineering Selection Recommendations

For Direct Replacement (Recommended Primary Choice): The 380LX182M100H452 from Cornell Dubilier Electronics is the optimal direct substitute. It maintains all critical electrical parameters, identical mechanical dimensions, and is RoHS3 compliant with active production status. The ESR specification of 130 mOhm is functionally equivalent to the original 129 mOhm.

For Applications with Relaxed Height Constraints: The 100MXG1800MEFCSN22X30 and 100MXG1800MEFCSN22X40 from Rubycon offer enhanced operating temperature capability (105°C versus 85°C) and are RoHS3 compliant. These parts are suitable when PCB layout permits height variations of 1.260" to 1.654".

For Applications with Reduced Voltage Requirements: The 80MXG1800MEFCSN22X30 is applicable only when the circuit operates at voltages not exceeding 80 V. This part provides identical capacitance and mechanical compatibility but reduced voltage rating.

For Legacy System Support with Lifetime Constraints: The B41231A9188M000 from EPCOS - TDK Electronics is suitable for applications where the reduced lifetime specification of 2000 hours at 85°C meets system requirements. This part is RoHS3 compliant and currently in production.

For Enhanced Performance: The SLP182M100A4P3 from Cornell Dubilier Electronics provides 3000 hours lifetime at the elevated temperature of 105°C, extending operational capability in thermally demanding environments. Height matches the original specification at 1.772".

Frequently Asked Questions (FAQ)

Q: Can the 80MXG1800MEFCSN22X30 be used as a direct replacement for the ECO-S2AP182BA?

A: The 80MXG1800MEFCSN22X30 is not a direct replacement due to its reduced voltage rating of 80 V versus the original 100 V specification. Use this part only in applications where the actual operating voltage does not exceed 80 V. Exceeding this voltage rating will compromise component reliability.

Q: What is the primary advantage of the 100MXG1800MEFCSN22X40 over the ECO-S2AP182BA?

A: The 100MXG1800MEFCSN22X40 extends the operating temperature range to 105°C and specifies 3000 hours lifetime at this elevated temperature, compared to the original 3000 hours at 85°C. This provides enhanced thermal performance for applications in higher-temperature environments. The trade-off is a height increase from 1.772" to 1.654".

Q: Are all substitute parts RoHS3 compliant?

A: Yes, all substitute parts listed are RoHS3 compliant. The original ECO-S2AP182BA is RoHS non-compliant. If RoHS compliance is a system requirement, any of the listed substitutes satisfy this criterion.

Q: Does the ESR specification difference between the ECO-S2AP182BA (129 mOhm) and the 380LX182M100H452 (130 mOhm) affect circuit performance?

A: The ESR difference of 1 mOhm is negligible for general-purpose applications. Both values fall within the same performance class for ripple current handling and thermal characteristics. The 380LX182M100H452 is functionally equivalent in this regard.

Q: What is the significance of the height variations among substitute parts?

A: Height variations affect PCB layout and mechanical clearance. The ECO-S2AP182BA specifies 1.772" (45.00 mm) height. Substitutes range from 1.260" to 1.850". Verify that selected substitute parts fit within available vertical space on the PCB. Shorter parts (1.260") provide additional clearance; taller parts (1.850") require confirmation of available space.

Q: Can the B41231A9188M000 be used in applications requiring 3000 hours lifetime at 85°C?

A: The B41231A9188M000 specifies 2000 hours lifetime at 85°C, which is 1000 hours less than the original specification. Use this part only in applications where the reduced lifetime meets system requirements. For applications requiring 3000 hours at 85°C, select the 380LX182M100H452 or SLP182M100A4P3.

Q: Are all substitute parts available in the same packaging format?

A: Yes, all substitute parts use the radial, can snap-in package with identical lead spacing of 0.394" (10.00 mm) and case diameter of 0.866" (22.00 mm). This ensures mechanical compatibility with the original PCB footprint.
