ECO-S2AP182DA Equivalent & Substitute Parts

Part Overview

The ECO-S2AP182DA is a 1800 µF, 100 V aluminum electrolytic capacitor in radial, can snap-in package manufactured by Panasonic Electronic Components. This component is classified as obsolete, making identification of equivalent substitute parts essential for ongoing system support and procurement planning. The part operates across a temperature range of -40°C to 85°C with a rated lifetime of 3000 hours at 85°C, serving general-purpose applications requiring stable capacitance and low equivalent series resistance.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ECO-S2AP182DA is determined by strict equivalence across the following critical parameters:

• Capacitance: 1800 µF (exact match required)
• Voltage Rating: 100 V (exact match required)
• Tolerance: ±20% (exact match required)
• Package Type: Radial, Can - Snap-In (exact match required)
• Lead Spacing: 0.394" (10.00 mm) (exact match required)
• Mounting Type: Through Hole (exact match required)
• Polarization: Polar (exact match required)

All substitute parts listed meet these core electrical and mechanical parameters. Variations in ESR, ripple current ratings, lifetime specifications, and operating temperature maximums are secondary considerations that may affect performance characteristics but do not preclude substitution when primary parameters align.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts—380LX182M100K022, B41231C9188M000, and SLP182M100E3P3—satisfy the core electrical and mechanical substitution criteria for the obsolete ECO-S2AP182DA.

For applications requiring strict compliance with current environmental regulations, 380LX182M100K022 (CDE) and SLP182M100E3P3 (CDE) are ROHS3 compliant and REACH unaffected, whereas B41231C9188M000 (EPCOS - TDK) is ROHS3 compliant with REACH unaffected status.

The 380LX182M100K022 and SLP182M100E3P3 both maintain the 3000-hour lifetime specification at elevated temperature. The B41231C9188M000 specifies 2000 hours at 85°C, representing a reduced lifetime rating. The SLP182M100E3P3 extends the maximum operating temperature to 105°C compared to the 85°C limit of the original part and 380LX182M100K022.

Height differences exist between substitute options: 380LX182M100K022 and B41231C9188M000 measure 1.260" (32.00 mm) seated height, while SLP182M100E3P3 matches the original 1.181" (30.00 mm) dimension. PCB layout constraints may necessitate selection of SLP182M100E3P3 where vertical clearance is limited.

Frequently Asked Questions (FAQ)

Q: Can 380LX182M100K022 be used as a direct replacement for ECO-S2AP182DA?

A: Yes. Both parts share identical capacitance (1800 µF), voltage rating (100 V), tolerance (±20%), lead spacing (10.00 mm), and package type (radial, can snap-in). The 380LX182M100K022 is active and ROHS3 compliant. The seated height increases from 1.181" to 1.260", which must be verified against PCB layout constraints.

Q: What is the difference between the three substitute parts?

A: All three meet core substitution criteria. 380LX182M100K022 and SLP182M100E3P3 maintain 3000-hour lifetime ratings; B41231C9188M000 specifies 2000 hours. SLP182M100E3P3 operates to 105°C maximum; the others to 85°C. SLP182M100E3P3 retains the original 1.181" height; the other two increase to 1.260".

Q: Are there compliance differences between substitute options?

A: All three substitutes are ROHS3 compliant. The 380LX182M100K022 and SLP182M100E3P3 are REACH unaffected. The B41231C9188M000 is also REACH unaffected. The original ECO-S2AP182DA is RoHS non-compliant and REACH affected.

Q: Does ESR variation between parts affect substitution suitability?

A: ESR values are provided for reference. The ECO-S2AP182DA specifies 138 mOhm @ 120 Hz; substitutes range from 140 to 147 mOhm. These variations fall within normal manufacturing tolerances for aluminum electrolytic capacitors and do not preclude substitution when all primary electrical and mechanical parameters align.

Q: Which substitute is recommended for space-constrained applications?

A: SLP182M100E3P3 maintains the original 1.181" (30.00 mm) seated height, matching the ECO-S2AP182DA dimension. If vertical clearance is limited, this part eliminates height-related redesign considerations.

Q: Can substitutes be interchanged within the same assembly?

A: All three substitutes meet the core substitution criteria and are mechanically compatible with through-hole mounting. However, the height difference between SLP182M100E3P3 (1.181") and the other two (1.260") must be considered if multiple units are used in the same assembly and visual alignment or clearance is a design constraint.
