ECO-S1HP822DA Equivalent & Substitute Parts

Part Overview

The ECO-S1HP822DA is an 8200 µF, 50 V aluminum electrolytic capacitor manufactured by Panasonic Electronic Components in the TS-UP series. This radial, can-style snap-in capacitor is designed for general-purpose applications with a rated lifetime of 3000 hours at 85°C. The part is currently obsolete, making equivalent and substitute parts necessary for ongoing system support and new designs requiring this capacitance and voltage rating.

Substitute Part Grouping Explanation

Substitution for the ECO-S1HP822DA is determined by strict equivalence in the following parameters:

Capacitance: 8200 µF (exact match required)
Voltage Rating: 50 V (exact match required)
Tolerance: ±20% (exact match required)
Package Type: 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)

Substitute parts are classified into three categories:

Direct Manufacturer Substitutes: Parts meeting all core electrical and mechanical parameters with identical or superior performance characteristics.

Similar Manufacturer Substitutes: Parts meeting all core parameters but with variations in physical dimensions (diameter or height) or secondary performance metrics (ESR, ripple current) that remain within acceptable operating ranges.

Parametric Equivalents: Parts meeting all core parameters with minor variations in ESR or ripple current specifications that do not affect functional compatibility in general-purpose applications.

Engineering Selection Recommendations

Direct Substitution (Identical Dimensions and Performance)

The SLPX822M050E5P3 from Cornell Dubilier Electronics provides direct substitution with matching physical dimensions (1.181" diameter × 1.378" height) and identical lifetime rating (3000 hours at 85°C). This part is RoHS3 compliant and carries active product status, ensuring long-term availability.

Dimensional Alternatives

The LLS1H822MELC from Nichicon meets all core electrical parameters with different physical dimensions (1.378" diameter × 1.260" height). This part is RoHS3 compliant and active. The 380LX822M050J452 from Cornell Dubilier Electronics also provides electrical equivalence with a more compact diameter (0.984") but increased height (1.850"), suitable for applications with different PCB layout constraints.

Lifetime Consideration

The B41231B6828M000 from EPCOS - TDK Electronics meets all electrical parameters but specifies a reduced lifetime of 2000 hours at 85°C compared to the 3000-hour rating of the original part. This part is RoHS3 compliant and active. Selection of this part requires confirmation that the reduced lifetime is acceptable for the intended application.

Compliance Status

All active substitute parts listed carry RoHS3 compliance or are ROHS3 compliant, ensuring regulatory alignment with current environmental standards. All parts maintain REACH unaffected or REACH affected status consistent with the original part classification.

Frequently Asked Questions (FAQ)

Q: Can I use a substitute part with different physical dimensions?

A: Yes, provided the lead spacing (0.394" / 10.00 mm) remains constant for PCB hole alignment. However, different diameter and height dimensions may require verification of available space on the PCB and clearance from adjacent components. Dimensional changes do not affect electrical function if all core parameters match.

Q: What is the significance of ESR differences between parts?

A: ESR (Equivalent Series Resistance) affects ripple current handling and heat generation. The original ECO-S1HP822DA specifies 40 mOhm at 120 Hz. Substitute parts with higher ESR values (57 mOhm) will generate slightly more heat under ripple current conditions. For general-purpose applications, this difference is typically acceptable. Applications with high ripple current requirements should prioritize parts with matching or lower ESR specifications.

Q: Why do some substitute parts have different lifetime ratings?

A: Lifetime ratings reflect the manufacturer's specification for capacitor degradation at rated temperature and voltage. The original part specifies 3000 hours at 85°C. The B41231B6828M000 specifies 2000 hours at 85°C. Selection depends on application requirements; if extended operational life is critical, parts with 3000-hour ratings are preferred.

Q: Are all substitute parts currently available?

A: All listed substitute parts carry active product status, indicating current manufacturing and availability. The original ECO-S1HP822DA is obsolete. Inventory levels vary by distributor and should be confirmed at the time of procurement.

Q: What does "Radial, Can - Snap-In" package mean?

A: This describes a through-hole aluminum electrolytic capacitor with radial leads (both leads exit from the same end) housed in a cylindrical aluminum can. The snap-in designation indicates the capacitor is designed for insertion into a PCB with snap-fit retention, common in industrial and power supply applications.

Q: Can I substitute a part with different tolerance?

A: No. All listed substitutes maintain the ±20% tolerance specification of the original part. Tolerance affects the acceptable range of actual capacitance values and must match the design requirements.
