ECO-S1HA392BA Equivalent & Substitute Parts

Part Overview

The ECO-S1HA392BA is a 3900 µF, 50 V aluminum electrolytic capacitor manufactured by Panasonic Electronic Components in the TS-HA series. This radial, can-style snap-in capacitor is designed for general-purpose applications requiring high capacitance in a compact through-hole package. The part is currently obsolete, making equivalent and substitute parts necessary for ongoing system support, maintenance, and new design implementations where the original specification remains applicable.

Engineering Selection Recommendations

For Direct Replacement (Minimum Disruption)

Select LGU1H392MELZ (Nichicon) or 50MXG3900MEFCSN20X40 (Rubycon) for applications requiring immediate substitution with active product status and ROHS3 compliance. Both maintain the original 3000 Hrs @ 105°C lifetime specification and are available in production quantities.

For Enhanced Reliability

Select LGY1H392MELZ40 (Nichicon) when system design permits component refresh. This upgrade substitute provides 5000 Hrs @ 105°C lifetime, extending service intervals and reducing maintenance frequency. Physical dimensions remain identical to the original part.

For Space-Constrained Designs

Select SLP392M050C3P3 (Cornell Dubilier Electronics) when PCB layout requires reduced height (1.181" vs. 1.654"). This part maintains 3000 Hrs @ 105°C lifetime and ROHS3 compliance, with increased diameter (0.984") that remains within standard snap-in footprint tolerances.

For Reduced ESR Applications

Select LP392M050C7P3 (Cornell Dubilier Electronics) when lower equivalent series resistance is beneficial. This part provides 85 mOhm @ 120Hz, lower than the original 64 mOhm specification, though lifetime is reduced to 1000 Hrs @ 105°C. Evaluate thermal cycling requirements before selection.

Compliance Considerations

All active substitute parts listed carry ROHS3 compliance certification. The original ECO-S1HA392BA does not specify RoHS status. All parts are classified under HTSUS 8532.22.0040 and ECCN EAR99, maintaining regulatory consistency for procurement and export documentation.

Frequently Asked Questions (FAQ)

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

A: Yes, within limits. All listed substitutes maintain the 0.394" (10.00 mm) lead spacing and snap-in package type required for PCB compatibility. Diameter and height variations (ranging from 0.787" to 1.181" diameter and 0.984" to 1.654" height) remain within standard snap-in capacitor mounting tolerances. Verify available PCB clearance before selecting parts with larger diameters or different height profiles.

Q: What is the difference between "Direct," "Upgrade," "Similar," and "Parametric Equivalent" classifications?

A: Direct substitutes meet all electrical and mechanical specifications with equivalent performance. Upgrade substitutes provide enhanced lifetime ratings (5000 Hrs vs. 3000 Hrs @ 105°C) while maintaining all other parameters. Similar substitutes meet all electrical specifications but vary in physical dimensions. Parametric equivalents meet all core specifications with comparable electrical performance across the operating range.

Q: Does ESR (Equivalent Series Resistance) affect part selection?

A: ESR affects ripple current handling and thermal performance. The original part specifies 64 mOhm @ 120Hz. Substitutes range from 85 mOhm (LP392M050C7P3) to 148.783 mOhm (398LMB050M2BF). Higher ESR increases heat dissipation; lower ESR improves efficiency. Select based on thermal design requirements and ripple current specifications in your application.

Q: Are all substitute parts ROHS3 compliant?

A: All active substitute parts listed carry ROHS3 compliance certification. The original Panasonic ECO-S1HA392BA does not specify RoHS status. If RoHS compliance is a procurement requirement, select from the active substitute list.

Q: What is the significance of the 3000 Hrs vs. 5000 Hrs lifetime rating?

A: Lifetime rating indicates expected operational hours at maximum rated temperature (105°C). The original part and most substitutes specify 3000 Hrs @ 105°C. The Nichicon LGY1H392MELZ40 provides 5000 Hrs @ 105°C, extending service life by 67%. For applications with continuous operation or high ambient temperatures, the upgrade substitute reduces maintenance frequency.

Q: Can I substitute a part with lower ripple current rating?

A: No. Ripple current capacity must meet or exceed application requirements. Substitutes provide ripple current ratings ranging from 1.9 A to 2.79 A @ 120 Hz. Verify that selected substitute meets or exceeds the ripple current specification in your circuit design.

Q: What packaging options are available?

A: All substitute parts are supplied in Radial, Can - Snap-In through-hole packages with 0.394" (10.00 mm) lead spacing. Packaging format (Bulk or specified) varies by manufacturer and distributor. Confirm packaging requirements with your procurement department.
