Substitute Part Grouping Explanation

Substitution eligibility is determined by strict adherence to the following electrical and mechanical parameters:

Critical Parameters (Must Match):

Capacitance: 4700 µF
Voltage Rating: 50 V
Tolerance: ±20%
Package Type: Radial, Can - Snap-In
Mounting Type: Through Hole
Lead Spacing: 0.394" (10.00 mm)
Polarization: Polar
Operating Temperature Range: -40°C to 105°C

Allowable Variations:

ESR: Substitute parts may have higher ESR values while maintaining functional equivalence
Lifetime @ 105°C: Substitute parts with equal or greater lifetime ratings are acceptable
Case Diameter and Height: Limited dimensional variation is permitted provided the part fits within the same footprint envelope and snap-in mounting compatibility is maintained
Ripple Current: Variations are acceptable if electrical performance requirements are met

Substitute parts are grouped by their relationship to the main part: Direct Manufacturer alternatives (active status, equivalent performance), Upgrade options (enhanced lifetime or compliance), and Similar alternatives (compatible but with dimensional or performance variations).

Engineering Selection Recommendations

Direct Replacement (Preferred for Footprint Compatibility):

SLP472M050A4P3 and LGU1H472MELZ are the primary direct replacements. Both maintain the 22.00 mm case diameter and 10.00 mm lead spacing of the original part. SLP472M050A4P3 offers equivalent 3000-hour lifetime with ROHS3 compliance and active product status. LGY1H472MELZ45 provides enhanced reliability with 5000-hour lifetime at 105°C, matching the original 47.00 mm height and maintaining full dimensional compatibility.

Active Product Status Advantage:

All substitute parts listed carry active product status, ensuring long-term availability and supply chain stability. The original ECO-S1HA472BA is obsolete; substitution is necessary for new designs and production continuity.

Compliance Considerations:

All substitute parts are ROHS3 compliant except where MSL or REACH status differs. LGY1H472MELZ45 and LGU1H472MELZ carry "Not Applicable" MSL ratings, indicating enhanced environmental stability. All parts maintain ECCN EAR99 and HTSUS 8532.22.0040 classifications consistent with the original part.

Dimensional Trade-offs:

Parts with identical case diameter (22.00 mm) and height (47.00 mm)—SLP472M050A4P3, B41252A6478M, 478LMB050M2BG, and LGU1H472MELZ—provide drop-in compatibility. Parts with larger case diameters (35.00 mm) such as 381LX472M050A012 and LP472M050H3P3 require PCB layout verification but offer alternative form factors for space-constrained applications.

ESR Performance:

The original part specifies 53 mOhm ESR @ 120 Hz. Substitute parts with higher ESR values (99 mOhm or greater) remain functionally equivalent for general-purpose applications. Selection should be based on ripple current handling requirements and thermal management in the target circuit.

Frequently Asked Questions (FAQ)

Q: Can I use a substitute part with higher ESR than the original ECO-S1HA472BA?

A: Yes. All substitute parts listed maintain the same capacitance, voltage rating, and operating temperature range. Higher ESR values are acceptable for general-purpose applications provided the circuit design accounts for increased heat dissipation. Verify ripple current specifications against your application requirements.

Q: Are all substitute parts drop-in replacements?

A: Parts with identical case diameter (22.00 mm) and height (47.00 mm) are direct drop-in replacements: SLP472M050A4P3, B41252A6478M, 478LMB050M2BG, and LGU1H472MELZ. Parts with larger case diameters require PCB layout verification to confirm snap-in mounting compatibility and clearance.

Q: What is the difference between the Direct, Upgrade, and Similar substitute categories?

A: Direct substitutes (SLP472M050A4P3) match the original specifications and form factor. Upgrade substitutes (LGY1H472MELZ45) offer enhanced performance, such as extended lifetime (5000 hours vs. 3000 hours). Similar substitutes maintain electrical equivalence but may have dimensional variations or lower lifetime ratings, requiring application-specific evaluation.

Q: Why does LGY1H472MELZ45 have a longer lifetime than the original part?

A: LGY1H472MELZ45 is rated for 5000 hours at 105°C compared to the original 3000 hours. This reflects different manufacturing processes and material formulations by Nichicon. The extended lifetime provides improved reliability for applications requiring long service intervals.

Q: Can I substitute a part with a different case diameter?

A: Parts with different case diameters (35.00 mm vs. 22.00 mm) require PCB layout verification. Lead spacing remains constant at 10.00 mm, but the larger diameter may conflict with adjacent components or mounting hardware. Confirm mechanical clearance and snap-in mounting compatibility before design implementation.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All substitute parts listed carry ROHS3 compliance certification. The original ECO-S1HA472BA does not specify RoHS status, but all active replacements meet current environmental regulations.

Q: What is the inventory status of substitute parts?

A: All substitute parts are in active production with confirmed stock availability. SLP472M050C5P3 has the highest inventory (23,234 pcs), while LGY1H472MELZ45 and LGU1H472MELZ offer strong availability (1,325 and 4,282 pcs respectively), ensuring supply chain continuity.
