Substitute Part Grouping Explanation

Substitution of the SN470M016ST is determined by the following critical parameters:

Electrical Compatibility:

• Capacitance value must be 47 µF (exact match required)
• Tolerance must be ±20% or tighter
• Voltage rating must be equal to or greater than 16 V
• Operating temperature range must encompass -40°C ~ 85°C
• Polarization must be Bi-Polar

Mechanical Compatibility:

• Mounting type must be Through Hole
• Package type must be Radial, Can
• Lead spacing must be 0.138" (3.50mm)
• Physical diameter must be 0.315" (8.00mm)
• Height (seated) must not exceed 0.453" (11.50mm)

Regulatory Compliance:

• RoHS3 compliance required

The ECE-A1VN470U from Panasonic Electronic Components meets all substitution criteria and is classified as an active product, providing long-term availability.

Engineering Selection Recommendations

The ECE-A1VN470U is a direct functional substitute for the SN470M016ST. Selection is based on the following engineering criteria:

Electrical Equivalence: Both components share identical capacitance (47 µF), tolerance (±20%), and operating temperature range (-40°C ~ 85°C). The ECE-A1VN470U features a higher voltage rating (35 V versus 16 V), which provides additional design margin and does not compromise circuit performance in applications rated for 16 V operation.

Mechanical Compatibility: Physical dimensions, lead spacing, and mounting configuration are identical between both parts, ensuring direct PCB compatibility without layout modifications.

Product Availability: The ECE-A1VN470U is classified as an active product with 6338 units in stock, compared to the obsolete SN470M016ST. This status ensures long-term supply chain reliability and continued manufacturing support.

Regulatory Compliance: Both components meet ROHS3 compliance requirements, satisfying environmental and regulatory standards for electronic component procurement.

Frequently Asked Questions (FAQ)

Q: Can the ECE-A1VN470U replace the SN470M016ST in existing designs?

A: Yes. The ECE-A1VN470U is electrically and mechanically compatible with the SN470M016ST. Identical capacitance, tolerance, operating temperature range, and physical dimensions ensure direct substitution without circuit redesign or PCB layout modification.

Q: Why does the ECE-A1VN470U have a higher voltage rating (35 V vs. 16 V)?

A: Higher voltage ratings do not negatively impact circuit performance in applications designed for lower voltages. The 35 V rating provides additional design margin and reliability headroom. The component will operate correctly in 16 V circuits.

Q: Are the lead spacings identical?

A: Yes. Both the SN470M016ST and ECE-A1VN470U feature 0.138" (3.50mm) lead spacing, ensuring compatibility with existing through-hole PCB footprints.

Q: What is the difference in ripple current specifications?

A: The ECE-A1VN470U specifies 120 mA ripple current at 120 Hz, compared to 115 mA for the SN470M016ST. This represents a marginal increase in ripple current handling capability and does not affect substitution suitability.

Q: Are both components RoHS compliant?

A: Yes. Both the SN470M016ST and ECE-A1VN470U are ROHS3 compliant, meeting environmental and regulatory requirements for electronic component manufacturing and procurement.

Q: What is the product status difference?

A: The SN470M016ST is classified as obsolete, indicating discontinued manufacturing. The ECE-A1VN470U is classified as active, ensuring ongoing availability, manufacturing support, and supply chain reliability for future production requirements.
