ECO-S2HP391EA Equivalent & Substitute Parts

Part Overview

The ECO-S2HP391EA is a 390 µF, 500 V aluminum electrolytic capacitor in radial, can snap-in package manufactured by Panasonic Electronic Components. This component is classified as obsolete, making identification of equivalent substitute parts essential for ongoing system support and component procurement.

The TS-UP series capacitor is designed for general-purpose applications requiring high voltage energy storage with specified ripple current handling at both low and high frequencies. Due to its obsolete status, direct replacement options from active manufacturers are necessary to maintain design continuity and ensure supply chain reliability.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the ECO-S2HP391EA is determined by strict equivalence across the following critical parameters:

• Capacitance Value: 390 µF (exact match required)
• Voltage Rating: 500 V (exact match required)
• Tolerance: ±20% (exact match required)
• Polarization: Polar (exact match required)
• Lead Spacing: 0.394" (10.00 mm) (exact match required)
• Case Diameter: 1.378" (35.00 mm) (exact match required)
• Mounting Type: Through Hole (exact match required)
• Package Type: Radial, Can - Snap-In (exact match required)

Substitute parts are classified into two categories based on parameter alignment:

Direct Equivalent: 380LX391M500A052 (Cornell Dubilier Electronics) — Matches all critical parameters including ESR specification of 425 mOhm @ 120Hz and identical lifetime rating.

Similar Equivalent: 380LX391M500A062 (Cornell Dubilier Electronics) — Matches all critical parameters with variation in ESR (516 mOhm @ 120Hz) and physical height (2.559" vs. 1.969"), indicating different internal construction while maintaining electrical ratings and mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

380LX391M500A052 is the primary substitute for ECO-S2HP391EA. This Cornell Dubilier Electronics component maintains identical electrical specifications including ESR and ripple current ratings. The part is active in production status with ROHS3 compliance and REACH unaffected certification, ensuring long-term availability and regulatory alignment. Physical height variation of 2.047" (52.00 mm) versus the original 1.969" (50.00 mm) represents a 2 mm increase requiring PCB layout verification for clearance compatibility.

380LX391M500A062 serves as an alternative substitute when higher ripple current capacity is acceptable. This variant exhibits elevated ESR (516 mOhm @ 120Hz) and increased physical height (2.559" or 65.00 mm), indicating different internal construction. The part maintains identical capacitance, voltage rating, and tolerance specifications. Selection of this variant is appropriate only when circuit design permits the higher ESR and physical envelope does not present mechanical constraints.

Both substitute parts are manufactured by Cornell Dubilier Electronics, an established supplier in the aluminum electrolytic capacitor market, and carry active product status with current regulatory compliance certifications.

Frequently Asked Questions (FAQ)

Q: Can 380LX391M500A052 be used as a direct replacement for ECO-S2HP391EA?

A: Yes. The 380LX391M500A052 matches all critical electrical and mechanical parameters including capacitance (390 µF), voltage rating (500 V), tolerance (±20%), ESR (425 mOhm @ 120Hz), and lead spacing (10.00 mm). Physical height increases by 2 mm, requiring verification that PCB layout and enclosure clearances accommodate this dimension.

Q: What is the difference between 380LX391M500A052 and 380LX391M500A062?

A: Both parts share identical capacitance, voltage, and tolerance specifications. The 380LX391M500A062 exhibits higher ESR (516 mOhm vs. 425 mOhm @ 120Hz) and greater physical height (65.00 mm vs. 52.00 mm). These differences indicate distinct internal construction. Selection depends on circuit ESR requirements and available physical space.

Q: Are the substitute parts compatible with the original PCB layout?

A: Lead spacing (10.00 mm) and case diameter (35.00 mm) are identical, ensuring through-hole mounting compatibility. Physical height variations require clearance verification. The 380LX391M500A052 adds 2 mm height; the 380LX391M500A062 adds 15 mm height. Confirm available vertical clearance before component selection.

Q: What regulatory certifications do the substitute parts carry?

A: Both Cornell Dubilier Electronics substitutes are ROHS3 compliant and REACH unaffected. These certifications align with current environmental and hazardous substance regulations applicable to electronic components.

Q: Why is the original ECO-S2HP391EA obsolete?

A: Product obsolescence reflects manufacturer discontinuation decisions. Active substitute parts from Cornell Dubilier Electronics provide equivalent electrical performance and current production status, ensuring supply chain continuity.

Q: Can either substitute part handle the same ripple current as the original?

A: The 380LX391M500A052 matches the original ripple current specifications (2.22 A @ 120 Hz, 3.11 A @ 20 kHz). The 380LX391M500A062 provides higher ripple current capacity (2.7 A @ 120 Hz, 3.6 A @ 20 kHz), suitable for applications requiring increased current handling.
