ECO-S2HP151CA Equivalent & Substitute Parts

Part Overview

The ECO-S2HP151CA is a 150 µF, 500 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 product is currently obsolete, making equivalent substitutes from active manufacturers necessary for ongoing system support and new designs requiring compatible performance characteristics.

Substitute Part Grouping Explanation

Substitution eligibility for the ECO-S2HP151CA is determined by strict equivalence in the following parameters:

Capacitance: 150 µF (exact match required)
Voltage Rating: 500 V (exact match required)
Tolerance: ±20% (exact match required)
Lead Spacing: 0.394" (10.00 mm) (exact match required)
Package Style: Radial, Can - Snap-In (exact match required)
Mounting Type: Through Hole (exact match required)
Operating Temperature Range: -25°C to 85°C (exact match required)
Lifetime @ 85°C: 3000 Hrs (exact match required)

All four substitute parts from Cornell Dubilier Electronics (CDE) meet these core electrical and mechanical requirements. Variations in ESR, case diameter, and height are permitted within the snap-in package family, as these do not affect functional compatibility in applications designed for the original part.

Engineering Selection Recommendations

All four Cornell Dubilier Electronics 380LX series parts are functionally equivalent substitutes for the obsolete ECO-S2HP151CA. Selection among these alternatives is based on the following criteria:

380LX151M500J452: Matches the original ESR specification exactly at 1.105 Ohm @ 120 Hz. This part provides the closest electrical performance match to the Panasonic original. ROHS3 compliant and currently in active production status.

380LX151M500J052: Offers the lowest ESR at 945 mOhm @ 120 Hz, resulting in reduced heat generation and improved ripple current handling at 1.4 A @ 120 Hz. Highest inventory availability at 1020 pieces. ROHS3 compliant.

380LX151M500K042: Provides the second-lowest ESR at 926 mOhm @ 120 Hz with the highest ripple current capacity at 1.6 A @ 120 Hz and 2.2 A @ 20 kHz. Suitable for applications requiring enhanced thermal performance. ROHS3 compliant.

380LX151M500A012: Features a larger case diameter (1.378" / 35.00 mm) and reduced height (1.063" / 27.00 mm), making it suitable for space-constrained applications where horizontal mounting space is available. ROHS3 compliant.

All substitute parts maintain the same lead spacing (0.394" / 10.00 mm), through-hole mounting configuration, and snap-in package style, ensuring direct mechanical compatibility with existing PCB designs.

Frequently Asked Questions (FAQ)

Q: Can I use any of these substitute parts interchangeably with the ECO-S2HP151CA?

A: Yes. All four Cornell Dubilier Electronics parts meet the core electrical and mechanical specifications: 150 µF capacitance, 500 V voltage rating, ±20% tolerance, 3000-hour lifetime at 85°C, and identical lead spacing and mounting type. Selection depends on specific application requirements regarding ESR, case dimensions, and ripple current handling.

Q: What is the difference between the substitute parts?

A: The primary differences are ESR values, case diameters, and heights. The 380LX151M500J452 matches the original ESR exactly. The 380LX151M500J052 and 380LX151M500K042 offer lower ESR values, reducing heat generation. The 380LX151M500A012 has a larger diameter but shorter height, suitable for different PCB layout constraints.

Q: Are all substitute parts RoHS compliant?

A: Yes. All four Cornell Dubilier Electronics substitute parts are ROHS3 compliant, meeting current environmental and regulatory requirements.

Q: Will the different case diameters affect PCB compatibility?

A: The lead spacing remains constant at 0.394" (10.00 mm) across all parts, ensuring PCB hole alignment compatibility. However, case diameter variations may affect clearance around the component. Verify available board space before selecting parts with larger diameters (380LX151M500A012 at 1.378" and 380LX151M500K042 at 1.181").

Q: Which substitute part should I choose for a new design?

A: For direct electrical performance matching, select 380LX151M500J452. For improved thermal performance and ripple current handling, select 380LX151M500J052 or 380LX151M500K042. For space-constrained layouts, select 380LX151M500A012. All are active production parts with adequate inventory availability.
