Substitute Part Grouping Explanation

Substitution for the ECO-S2HP151EA is determined by strict equivalence across 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 Type: 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)

Engineering Selection Recommendations

All four Cornell Dubilier Electronics 380LX series parts are functionally equivalent substitutes for the obsolete ECO-S2HP151EA. Selection among these alternatives should be based on the following factors:

Product Status: All substitute parts carry Active product status, ensuring long-term availability and supply chain continuity compared to the obsolete Panasonic original.

Compliance: All substitute parts are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Physical Fit: The 380LX151M500A012 maintains the closest dimensional match to the original part, with identical can diameter (1.378" / 35.00 mm). The 380LX151M500J052 and 380LX151M500J452 feature smaller can diameters (0.984" / 25.00 mm) and taller heights, requiring verification of available board space. The 380LX151M500K042 offers a mid-range diameter (1.181" / 30.00 mm) with moderate height.

Electrical Performance: The 380LX151M500J052 and 380LX151M500K042 offer lower ESR values (945 mOhm and 926 mOhm respectively), providing improved ripple current handling. The 380LX151M500J452 matches the original ESR specification exactly at 1.105 Ohm.

Frequently Asked Questions (FAQ)

Q: Can I use any of these substitute parts interchangeably with the ECO-S2HP151EA?

A: Yes, all four Cornell Dubilier Electronics 380LX series parts are electrically and mechanically equivalent substitutes. They share identical capacitance (150 µF), voltage rating (500 V), tolerance (±20%), lead spacing (10.00 mm), operating temperature range (-25°C to 85°C), and lifetime rating (3000 hours @ 85°C). Physical dimensions vary, so board layout compatibility must be verified.

Q: What is the primary reason for substitution?

A: The ECO-S2HP151EA is obsolete. All substitute parts are active products from Cornell Dubilier Electronics, ensuring ongoing availability and supply chain support.

Q: Do the substitute parts meet current environmental standards?

A: Yes, all substitute parts are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements.

Q: How do ESR differences affect component selection?

A: ESR (Equivalent Series Resistance) influences ripple current handling and heat dissipation. Lower ESR values (380LX151M500J052 at 945 mOhm and 380LX151M500K042 at 926 mOhm) provide better performance in high-ripple-current applications. The 380LX151M500J452 matches the original ESR at 1.105 Ohm.

Q: Are there physical space constraints I should consider?

A: Yes. The 380LX151M500A012 maintains the original can diameter of 1.378" (35.00 mm). The 380LX151M500J052 and 380LX151M500J452 have smaller diameters (0.984" / 25.00 mm) but greater heights (2.047" and 1.850" respectively). The 380LX151M500K042 offers a compromise with 1.181" (30.00 mm) diameter and 1.654" (42.00 mm) height. Verify available board space before selection.

Q: What is the lead spacing for all parts?

A: All parts, including the original and all substitutes, have a lead spacing of 0.394" (10.00 mm), ensuring PCB footprint compatibility.
