Substitute Part Grouping Explanation

Substitution of the ECO-S1CP472BA is determined by strict adherence to the following electrical and mechanical parameters:

Critical Parameters for Direct Substitution:

Capacitance: 4700 µF (exact match required)
Voltage Rating: 16 V minimum (equal or higher acceptable)
Tolerance: ±20% (matching tolerance class)
Package / Case: Radial, Can - Snap-In (physical compatibility)
Lead Spacing: 0.394" (10.00 mm) (PCB layout compatibility)
Package Dimensions: 0.866" Dia × 1.063" Height (mechanical fit)
Mounting Type: Through Hole (assembly process compatibility)
Polarization: Polar (electrical polarity requirement)

Performance Parameters Considered:

ESR @ 120 Hz (lower values indicate improved performance)
Ripple Current @ 120 Hz (higher values indicate greater current handling)
Operating Temperature Range (wider range provides design flexibility)
Lifetime @ Temperature (longer life indicates reliability)

Substitute parts are categorized as direct equivalents when all critical parameters match the original specification. Upgrade substitutes offer improved electrical performance (lower ESR, higher ripple current, extended lifetime, or higher voltage rating) while maintaining mechanical compatibility and the same capacitance value.

Engineering Selection Recommendations

Direct Equivalent (16 V Rating):

The 381LX472M016H012 (Cornell Dubilier) and 380LX472M016H012 (Cornell Dubilier) are direct equivalents maintaining the 16 V voltage rating. Both parts are active products with RoHS3 compliance and REACH unaffected status. The 381LX472M016H012 offers improved ESR performance (150 mOhm vs. 159 mOhm) and extended operating temperature range (-40°C to 105°C), while the 380LX472M016H012 provides parametric equivalence with matching ESR and ripple current specifications.

Upgrade Substitutes (25 V Rating):

The 380LX472M025H012, 381LX472M025H012, 478LBB025M2BC, LGU1E472MELZ, and LGY1E472MELZ25 are upgrade substitutes with 25 V voltage rating. These parts maintain mechanical compatibility and capacitance value while providing enhanced electrical performance. The 380LX472M025H012 delivers the lowest ESR (110 mOhm) and highest ripple current (2.4 A @ 120 Hz). The LGY1E472MELZ25 (Nichicon) offers the longest lifetime rating (5000 Hrs @ 105°C) with extended operating temperature range. All upgrade substitutes are active products with RoHS3 compliance and REACH unaffected status.

Selection between direct equivalents and upgrade substitutes depends on circuit voltage headroom requirements and thermal performance needs. Upgrade substitutes are suitable for applications where the circuit design permits 25 V operation, providing improved reliability margins and reduced thermal stress.

Frequently Asked Questions (FAQ)

Q: Can I use a 25 V rated substitute in place of the 16 V original part?

A: Yes, provided the circuit design permits operation at 25 V. Higher voltage-rated capacitors are electrically compatible with lower voltage circuits. The 25 V substitutes offer improved ESR and ripple current performance, making them suitable for most applications. Verify that the circuit topology and component ratings support 25 V operation.

Q: What is the significance of ESR (Equivalent Series Resistance) in capacitor selection?

A: ESR directly affects capacitor performance in ripple current applications and thermal stability. Lower ESR values reduce heat generation and improve transient response. The substitute parts offer ESR values ranging from 105.82 mOhm to 160 mOhm, with lower values providing superior performance in high-frequency switching applications.

Q: Are all substitute parts mechanically compatible with the original PCB layout?

A: Yes. All listed substitute parts maintain identical lead spacing (0.394" / 10.00 mm), package diameter (0.866" / 22.00 mm), and height (1.063" / 27.00 mm). They are all through-hole mounted radial, can snap-in packages, ensuring direct PCB compatibility without layout modifications.

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

A: Direct equivalents (381LX472M016H012, 380LX472M016H012) maintain the 16 V voltage rating and provide comparable electrical performance to the original part. Upgrade substitutes feature 25 V voltage rating with improved ESR, ripple current, or lifetime specifications. Selection depends on circuit voltage requirements and performance objectives.

Q: Do all substitute parts meet RoHS and REACH compliance requirements?

A: All active substitute parts listed are RoHS3 compliant and REACH unaffected. The original ECO-S1CP472BA is REACH affected due to its obsolete status. Substitution with active parts ensures compliance with current environmental and regulatory standards.

Q: What is the lifetime rating and how does it affect component selection?

A: Lifetime rating indicates the expected operational duration at specified temperature. The original part is rated 3000 Hrs @ 85°C. Substitute parts offer 3000 Hrs @ 85°C, 3000 Hrs @ 105°C, or 5000 Hrs @ 105°C. Extended lifetime ratings at higher temperatures provide design margin for thermal stress and long-term reliability in demanding applications.
