Equivalent & Substitute Parts for 474SMH050M

Part Overview

The 474SMH050M is a 0.47 µF, 50 V aluminum electrolytic capacitor manufactured by Cornell Dubilier / Illinois Capacitor in the SMH series. This surface mount component is designed for general purpose applications requiring polar capacitive storage in compact form factors. The part is currently active in production with 1083 units in stock. Substitute parts are identified to provide alternative sourcing options when the primary part becomes unavailable or when design requirements necessitate different performance characteristics within the same electrical and mechanical specifications.

Engineering Selection Recommendations

Both the 474SMH050M and MAL215371477E3 are active production components with full RoHS3 compliance and MSL 1 rating. Selection between these parts should be based on:

Availability and Lead Time: The MAL215371477E3 (Vishay Beyschlag/Draloric/BC Components) currently has higher inventory availability at 8467 units compared to 1083 units for the 474SMH050M. This may influence procurement decisions for high-volume applications.

Physical Compatibility: The MAL215371477E3 has a maximum seated height of 0.209" (5.30 mm) compared to 0.217" (5.50 mm) for the 474SMH050M. Both dimensions are compatible with standard PCB layouts designed for 0.157" diameter SMD aluminum electrolytic capacitors with 4.30 mm x 4.30 mm land patterns.

Packaging Format: The 474SMH050M is supplied in standard packaging, while the MAL215371477E3 is supplied in Tape & Reel (TR) format. Selection depends on assembly process requirements and order quantities.

Both parts satisfy all electrical and mechanical requirements for direct substitution in general purpose applications operating within the -55°C to 105°C temperature range.

Frequently Asked Questions (FAQ)

Q: Can MAL215371477E3 be used as a direct replacement for 474SMH050M in existing designs?

A: Yes. Both parts are electrically and mechanically equivalent with identical capacitance (0.47 µF), voltage rating (50 V), tolerance (±20%), operating temperature range (-55°C to 105°C), and surface mount land pattern (0.169" L x 0.169" W). The MAL215371477E3 has a slightly lower maximum height (0.209" vs 0.217"), which is compatible with standard PCB layouts.

Q: What are the critical parameters that must match for substitution?

A: Capacitance value, voltage rating, tolerance, polarization, package type (Radial, Can - SMD), mounting type (Surface Mount), surface mount land size, RoHS compliance status, and moisture sensitivity level must all be identical. Operating temperature range and physical diameter must also match.

Q: Are there any compliance differences between these parts?

A: No. Both parts are ROHS3 compliant, have MSL 1 rating (unlimited moisture sensitivity), and are REACH unaffected with EAR99 ECCN classification.

Q: Does the height difference between 474SMH050M (0.217") and MAL215371477E3 (0.209") affect PCB design?

A: No. The MAL215371477E3 is shorter and will fit within any PCB clearance designed for the 474SMH050M. Both parts use identical surface mount land patterns and are compatible with standard pick-and-place assembly equipment.

Q: What packaging formats are available?

A: The 474SMH050M is supplied in standard packaging. The MAL215371477E3 is supplied in Tape & Reel (TR) format, which is standard for high-volume surface mount assembly operations.
