ECE-S2GP471EX Equivalent & Substitute Parts

Part Overview

The ECE-S2GP471EX is a 470 µF, 400 V aluminum electrolytic capacitor in radial, can snap-in package manufactured by Panasonic Electronic Components. This part is classified as obsolete, making equivalent substitutes necessary for ongoing production and maintenance applications. The capacitor is designed for general-purpose applications requiring 400 V rated voltage with ±20% capacitance tolerance and 3000 hours lifetime at 85°C operating temperature.

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict equivalence across the following parameters: capacitance (470 µF), voltage rating (400 V), tolerance (±20%), package type (radial, can snap-in), mounting type (through hole), lead spacing (10.00 mm), and diameter (35.00 mm). Height variation is permitted within the mechanical envelope constraints of snap-in mounting. Lifetime rating at operating temperature and ESR characteristics are secondary parameters that may vary between manufacturers while maintaining functional equivalence. All substitute parts listed meet the core electrical and mechanical requirements for direct replacement in the ECE-S2GP471EX application.

Engineering Selection Recommendations

Direct substitutes with identical height (1.575" / 40.00 mm) and matching 3000 Hrs @ 85°C lifetime are LGU2G471MELC, LGW2G471MELC40, and SLPX471M400H7P3. These parts maintain the original form factor and thermal performance envelope. LGU2G471MELC and LGW2G471MELC40 offer extended operating temperature range to 105°C, providing thermal margin for applications operating near the original 85°C limit.

For applications where reduced height is acceptable within the snap-in mounting envelope, Rubycon 400USG470MEFC35X30 and 400USG470MEFCSN35X30 provide compact alternatives at 1.260" (32.00 mm). The 400USG470MEFCSN35X30 variant is ROHS3 compliant, whereas the standard 400USG470MEFC35X30 is RoHS non-compliant.

Würth Elektronik 861221386021 and Chemi-Con ESMM401VSN471MA35S and ESMM401VSN471MA35W offer intermediate height at 1.457" (37.00 mm) with active product status and RoHS compliance. Nichicon LLS2G471MELC matches the original diameter exactly at 1.378" (35.00 mm) with reduced height at 1.378" (35.00 mm) and ROHS3 compliance.

All listed substitutes maintain the required 470 µF capacitance, 400 V voltage rating, ±20% tolerance, 10.00 mm lead spacing, and 35.00 mm diameter. Selection should prioritize active product status and compliance certifications appropriate to the application's regulatory requirements.

Frequently Asked Questions (FAQ)

Q: Can I use a substitute part with different height than the original ECE-S2GP471EX?

A: Yes. The snap-in mounting mechanism accommodates height variation. Verify that the substitute height does not exceed the available vertical space in the application. Rubycon parts at 1.260" (32.00 mm) are shorter; Würth Elektronik and Chemi-Con parts at 1.457" (37.00 mm) are intermediate; Nichicon LGU2G471MELC, LGW2G471MELC40, and CDE SLPX471M400H7P3 match the original 1.575" (40.00 mm) height.

Q: What is the difference between 400USG470MEFC35X30 and 400USG470MEFCSN35X30?

A: Both are Rubycon 470 µF, 400 V snap-in capacitors with identical electrical specifications. The primary difference is RoHS compliance: 400USG470MEFC35X30 is RoHS non-compliant, while 400USG470MEFCSN35X30 is ROHS3 compliant. Select based on regulatory requirements for your application.

Q: Are Nichicon LGU2G471MELC and LGW2G471MELC40 interchangeable?

A: Both are 470 µF, 400 V Nichicon capacitors with identical height (1.575" / 40.00 mm), lead spacing (10.00 mm), and diameter (35.00 mm). Both offer 3000 Hrs @ 105°C lifetime. They are electrically and mechanically interchangeable for the ECE-S2GP471EX application.

Q: Can I substitute with a part rated for 3000 Hrs @ 105°C instead of 3000 Hrs @ 85°C?

A: Yes. A higher temperature rating (105°C) provides equivalent or superior performance at the original operating temperature (85°C). Nichicon LGU2G471MELC and LGW2G471MELC40 are suitable upgrades offering extended thermal margin.

Q: What does "snap-in" package mean for mechanical compatibility?

A: Snap-in refers to the mounting mechanism where the capacitor leads engage with spring-loaded contacts on the PCB. All listed substitutes use identical snap-in mounting with 10.00 mm lead spacing and 35.00 mm diameter, ensuring mechanical compatibility with the original ECE-S2GP471EX footprint.

Q: Which substitute has the lowest ESR?

A: ESR data is not provided for most substitutes. Rubycon and Nichicon parts do not specify ESR. Panasonic ECE-S2GP471EX specifies 388 mOhm @ 120 Hz; Chemi-Con ESMM401VSN471MA35S and ESMM401VSN471MA35W specify 705 mOhm @ 120 Hz; CDE SLPX471M400H7P3 specifies 423 mOhm @ 120 Hz. For applications sensitive to ESR, CDE SLPX471M400H7P3 provides comparable performance to the original.
