Substitute Part Grouping Explanation

Substitution eligibility for the ECO-S1HP472BA is determined by strict equivalence across the following parameters:

Capacitance Value: 4700 µF (exact match required)
Voltage Rating: 50 V (exact match required)
Tolerance: ±20% (exact match required)
Package Configuration: Radial, Can - Snap-In (exact match required)
Lead Spacing: 0.394" (10.00 mm) (exact match required)
Mounting Type: Through Hole (exact match required)
Operating Temperature Range: -40°C to 85°C (exact match required)
Polarization: Polar (exact match required)

All identified substitute parts meet these core electrical and mechanical criteria. Variations in physical dimensions (diameter and height), ESR characteristics, and ripple current ratings are permissible within the scope of general-purpose applications, provided the primary electrical specifications remain constant.

Engineering Selection Recommendations

All substitute parts listed maintain active product status with current manufacturer support, ensuring long-term availability and supply chain stability. The following considerations apply to component selection:

Cornell Dubilier Electronics (CDE) 380LX Series (380LX472M050H032, 380LX472M050J022): These parts offer RoHS3 compliance and REACH unaffected status. The 380LX472M050H032 maintains the original 22.00 mm diameter with a 2 mm height increase. The 380LX472M050J022 increases to 25.00 mm diameter with reduced height, suitable for applications with lateral space constraints.

EPCOS - TDK Electronics B41231A6478M000: This part provides RoHS3 compliance but features a reduced lifetime rating of 2000 hours at 85°C compared to the 3000-hour specification of the original part. Physical dimensions match the original diameter (22.00 mm) but with increased height (42.00 mm). MSL classification is not applicable.

Cornell Dubilier Electronics (CDE) SLPX Series (SLPX472M050A7P3, SLPX472M050C3P3, SLPX472M050E1P3): These parts deliver improved ESR performance at 99 mOhm compared to the original 71 mOhm specification, with full RoHS3 compliance and REACH unaffected status. The SLPX472M050A7P3 maintains the original 22.00 mm diameter. The SLPX472M050C3P3 and SLPX472M050E1P3 offer alternative form factors with 25.00 mm and 30.00 mm diameters respectively, accommodating diverse PCB layout requirements.

Frequently Asked Questions (FAQ)

Q: Can the ECO-S1HP472BA be directly replaced with any of these substitute parts?

A: Yes, all listed parts are electrically and mechanically equivalent within the scope of general-purpose applications. All maintain 4700 µF capacitance, 50 V voltage rating, ±20% tolerance, and identical lead spacing (10.00 mm). Physical dimensions vary, requiring verification of available PCB space before installation.

Q: What is the significance of ESR differences between the original part and substitutes?

A: The original ECO-S1HP472BA specifies 71 mOhm ESR at 120 Hz. Substitute parts range from 99 mOhm to 110 mOhm. Lower ESR values reduce heat generation and improve ripple current handling. Higher ESR values remain within acceptable ranges for general-purpose applications but may require thermal evaluation in high-ripple-current environments.

Q: Does the B41231A6478M000 have any limitations compared to other substitutes?

A: The B41231A6478M000 specifies a reduced lifetime of 2000 hours at 85°C versus the 3000-hour rating of the original part and other substitutes. This part is suitable for applications with lower thermal stress or shorter operational lifespans. ESR data is not provided for this part.

Q: Are all substitute parts RoHS3 compliant?

A: Yes, all active substitute parts listed carry RoHS3 compliance certification. The original ECO-S1HP472BA is obsolete and does not carry RoHS3 status.

Q: How do physical dimension variations affect component selection?

A: All parts maintain the required 10.00 mm lead spacing and through-hole mounting configuration. Diameter and height variations must be evaluated against available PCB space. The SLPX472M050C3P3 and SLPX472M050E1P3 offer compact form factors with reduced heights (30.00 mm and 25.00 mm respectively), suitable for space-constrained designs.

Q: What is the REACH compliance status of these parts?

A: The original ECO-S1HP472BA is REACH Affected. All active substitute parts are REACH Unaffected, providing regulatory advantage for new designs and long-term supply chain compliance.
