Parameter Comparison

Engineering Selection Recommendations

All three parts listed—475SMH050M, MAL215371478E3, and SHT50V4R7ME054—are active production components with full RoHS compliance and MSL 1 moisture sensitivity ratings. Selection among these equivalents is based on the following engineering criteria:

475SMH050M (Cornell Dubilier / Illinois Capacitor): Primary choice when original manufacturer specification is required. ROHS3 compliant. 1000-hour lifetime at 105°C. 755 units currently in stock.

MAL215371478E3 (Vishay Beyschlag/Draloric/BC Components): Upgrade option offering extended lifetime (2000 hours at 105°C) and lower ESR (6 Ohm @ 100 kHz). ROHS3 compliant. Supplied in Tape & Reel packaging. 9332 units currently in stock. Suitable for applications where reduced ESR and extended thermal life are beneficial.

SHT50V4R7ME054 (Meritek): Parametric equivalent with matching electrical and mechanical specifications. RoHS compliant. 1000-hour lifetime at 105°C. 1048 units currently in stock. Suitable for general purpose substitution where manufacturer flexibility is acceptable.

All three parts meet the mandatory electrical, mechanical, and compliance requirements for direct interchange in the 475SMH050M application footprint.

Frequently Asked Questions (FAQ)

Q: Can MAL215371478E3 be used as a direct replacement for 475SMH050M?

A: Yes. MAL215371478E3 meets all mandatory electrical parameters (4.7 µF, 50 V, ±20% tolerance), physical dimensions (0.197" diameter, 0.217" height, 5.30mm x 5.30mm land size), and compliance requirements (ROHS3, MSL 1). The part is mechanically and functionally interchangeable on the PCB footprint designed for 475SMH050M.

Q: What is the difference between the three substitute parts?

A: All three parts share identical capacitance, voltage rating, tolerance, package type, and physical dimensions. Differences exist in ESR characteristics, thermal lifetime ratings, and packaging format. MAL215371478E3 offers lower ESR (6 Ohm @ 100 kHz) and extended lifetime (2000 hours at 105°C). SHT50V4R7ME054 provides a parametric equivalent with standard lifetime (1000 hours at 105°C).

Q: Are all substitute parts RoHS compliant?

A: Yes. 475SMH050M and MAL215371478E3 are ROHS3 compliant. SHT50V4R7ME054 is RoHS compliant. All three parts meet regulatory requirements for lead-free and restricted substance compliance.

Q: What is the moisture sensitivity level for these capacitors?

A: All three parts carry MSL 1 (Unlimited) rating, indicating unlimited shelf life under standard storage conditions without special moisture control measures.

Q: Can these parts be used interchangeably in high-ripple-current applications?

A: Ripple current specifications differ among the three parts. 475SMH050M supports 23 mA @ 120 Hz and 34.5 mA @ 100 kHz. MAL215371478E3 supports 17 mA @ 100 Hz. SHT50V4R7ME054 supports 19 mA @ 120 Hz. Application-specific ripple current requirements must be evaluated against the rated values for each part.

Q: What packaging formats are available?

A: 475SMH050M and SHT50V4R7ME054 packaging format is not specified in the data. MAL215371478E3 is supplied in Tape & Reel (TR) format, suitable for automated assembly processes.

Q: Are these parts suitable for operating at the full -55°C to 105°C temperature range?

A: Yes. All three parts are rated for continuous operation across the -55°C to 105°C temperature range. Thermal lifetime specifications (1000 or 2000 hours at 105°C) apply to the maximum operating temperature condition.
