Substitute Part Grouping Explanation

Substitution for the ECO-S1HA222BA is determined by the following mandatory parameters:

Capacitance: 2200 µF (exact match required)
Voltage Rating: 50 V minimum (higher voltage ratings are acceptable upgrades)
Tolerance: ±20% (standard tolerance for aluminum electrolytic capacitors)
Package Type: Radial, Can - Snap-In (mechanical and electrical interface requirement)
Lead Spacing: 0.394" (10.00 mm) (PCB footprint compatibility)
Mounting Type: Through Hole (assembly process compatibility)
Polarization: Polar (electrical polarity requirement)

Substitute parts are categorized as follows:

Direct Substitutes (50 V Rating): Parts maintaining the original 50 V voltage specification with identical mechanical dimensions and lead spacing.

Upgrade Substitutes (63 V Rating): Parts with elevated voltage rating (63 V) that provide enhanced voltage margin while maintaining all other mechanical and electrical parameters. These are suitable for applications where higher voltage headroom is beneficial.

Similar Substitutes (Dimensional Variations): Parts with matching electrical specifications but different physical dimensions or height configurations. These require PCB layout verification before implementation.

Engineering Selection Recommendations

Direct Substitutes (Recommended for Pin-Compatible Replacement):

B41505A6228M000 and B41505A6228M7 from EPCOS - TDK Electronics are direct substitutes with identical mechanical dimensions and lead spacing. Both parts are ROHS3 compliant and active in production. These parts offer improved ESR (85 mOhm versus 105 mOhm) and extended lifetime (5000 hours versus 3000 hours at 105°C), providing performance enhancement over the obsolete ECO-S1HA222BA.

Upgrade Substitutes (Higher Voltage Margin):

228LMB063M2BE (Cornell Dubilier / Illinois Capacitor), LGU1J222MELZ, and LGY1J222MELZ35 (Nichicon) provide 63 V voltage rating while maintaining identical mechanical footprint and lead spacing. These upgrades are suitable for applications requiring additional voltage headroom. LGY1J222MELZ35 offers extended 5000-hour lifetime at 105°C. All three are ROHS3 compliant and active in production.

Similar Substitutes (Dimensional Verification Required):

SLP222M050A3P3, 381LX222M050K202, LP222M050A5P3, and LP222M050E1P3 maintain the 50 V voltage specification and 10.00 mm lead spacing but feature different physical dimensions. These parts require PCB layout verification to confirm clearance and mounting compatibility before implementation. All are ROHS3 compliant and active in production.

Frequently Asked Questions (FAQ)

Q: Can I use a 63 V rated capacitor in place of the 50 V ECO-S1HA222BA?

A: Yes. A higher voltage rating (63 V) is electrically compatible with a 50 V application. The capacitor will operate safely with additional voltage margin. Mechanical dimensions and lead spacing must remain identical for PCB compatibility.

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

A: ESR affects ripple current handling and heat generation. Lower ESR values indicate better high-frequency performance. The B41505 series (85 mOhm) provides lower ESR than the original ECO-S1HA222BA (105 mOhm), resulting in improved thermal performance and ripple current capability.

Q: Are all substitute parts RoHS compliant?

A: All active substitute parts listed are ROHS3 compliant. The original ECO-S1HA222BA is REACH Affected; all substitute parts are REACH Unaffected, providing improved regulatory compliance for new designs.

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

A: Direct substitutes maintain identical physical dimensions (0.866" diameter, 1.457" height) and lead spacing (10.00 mm), allowing drop-in replacement without PCB modification. Similar substitutes have different physical dimensions and require PCB layout verification to confirm mechanical clearance and mounting compatibility.

Q: Does lifetime rating affect part selection?

A: Lifetime rating indicates operational duration at maximum rated temperature (105°C). The original part specifies 3000 hours. Substitute parts with 5000-hour ratings (B41505 series, LGY1J222MELZ35) provide extended operational life. Parts with 1000-hour ratings (LP series) have reduced lifetime and should be evaluated against application requirements.

Q: Can I substitute parts with different physical dimensions?

A: Similar substitutes with different dimensions require PCB layout verification. Lead spacing (10.00 mm) must remain constant for electrical connection. Diameter and height variations may affect mechanical clearance, thermal dissipation, and mounting stability. Confirm available space and mounting constraints before implementation.
