Substitute Part Grouping Explanation

Substitution eligibility for the ECO-S2GP101CA is determined by the following mandatory parameters:

Capacitance: 100 µF (exact match required)
Voltage Rating: 400 V minimum (equal or higher voltage acceptable)
Tolerance: ±20% (matching tolerance required)
Package Type: Radial, Can - Snap-In (mechanical compatibility required)
Mounting Type: Through Hole (board interface compatibility required)
Lead Spacing: 0.394" (10.00 mm) (exact match required for PCB hole alignment)
Polarization: Polar (electrical polarity requirement)

Direct substitutes maintain identical electrical and mechanical specifications. Upgrade substitutes offer improved performance characteristics such as lower ESR, extended lifetime at higher temperatures, or higher voltage ratings while maintaining mechanical compatibility. Similar parts share core electrical specifications but may have dimensional variations that require mechanical validation.

Engineering Selection Recommendations

Direct Substitutes (Preferred for Drop-In Replacement)

The 380LX101M400J012 from Cornell Dubilier Electronics is the primary direct substitute. It maintains identical electrical specifications and mechanical dimensions as the ECO-S2GP101CA, with equivalent ESR and lifetime ratings. This part is currently in active production status and ROHS3 compliant, making it suitable for new designs and ongoing production.

Upgrade Substitutes (Enhanced Performance)

The 381LR101M400J012 offers improved performance with lower ESR (1.326 Ω versus 1.658 Ω) and extended operating temperature range (-25°C to 105°C). This part maintains the same mechanical footprint and is ROHS3 compliant and active in production.

The B43501B9107M000 from EPCOS - TDK Electronics provides significantly lower ESR (0.660 Ω) and extended lifetime (10000 Hrs @ 85°C). However, this part is classified as "Not For New Designs," limiting its use to legacy system maintenance only.

Higher Voltage Alternatives

The 381LR101M420J012 (420 V) and LGUW6101MELA (420 V) provide voltage margin above the original 400 V specification while maintaining mechanical compatibility. The LGW2W101MELA25 (450 V) and LLS2W101MELA (450 V) offer additional voltage headroom for applications requiring enhanced safety margins.

Dimensional Variations

The 380LX101M400H022 and 380LX101M400K202 maintain electrical compatibility but feature different physical dimensions. These parts require mechanical validation to confirm PCB mounting compatibility before implementation.

Frequently Asked Questions (FAQ)

Q: Can I use a 420 V or 450 V rated capacitor in place of the 400 V ECO-S2GP101CA?

A: Yes. Higher voltage-rated capacitors are electrically compatible with lower voltage applications. The 381LR101M420J012, LGUW6101MELA, LGW2W101MELA25, and LLS2W101MELA all maintain the required 100 µF capacitance and ±20% tolerance while providing voltage ratings equal to or exceeding 400 V. Mechanical compatibility must be confirmed for each application.

Q: What is the difference between direct substitutes and upgrade substitutes?

A: Direct substitutes maintain identical specifications to the original part, including ESR, lifetime, and operating temperature range. Upgrade substitutes offer improved electrical performance (lower ESR, extended lifetime, or higher temperature ratings) while maintaining mechanical compatibility and core electrical specifications (capacitance, tolerance, voltage rating).

Q: Are all substitute parts ROHS3 compliant?

A: All recommended active production substitutes are ROHS3 compliant. The B43501B9107M000 is ROHS3 compliant but classified as "Not For New Designs." The original ECO-S2GP101CA is REACH Affected; all active substitutes are REACH Unaffected.

Q: Does ESR (Equivalent Series Resistance) affect part selection?

A: ESR is a performance characteristic that affects ripple current handling and heat dissipation. Lower ESR values indicate better high-frequency performance. The 381LR101M400J012 (1.326 Ω) and B43501B9107M000 (0.660 Ω) provide lower ESR than the original part (1.658 Ω), beneficial for applications with high ripple current requirements.

Q: Can I use parts with different physical dimensions?

A: The 380LX101M400H022 (22.00 mm diameter, 32.00 mm height) and 380LX101M400K202 (30.00 mm diameter, 22.00 mm height) have different dimensions than the original ECO-S2GP101CA (25.00 mm diameter, 25.00 mm height). Mechanical validation is required to confirm PCB hole alignment and mounting clearance before implementation.

Q: What is the significance of the 10.00 mm lead spacing specification?

A: The 0.394" (10.00 mm) lead spacing defines the distance between the two radial leads on the PCB. This dimension must match exactly for direct mounting compatibility. All listed substitutes maintain this specification.
