SEK472M016ST Equivalent & Substitute Parts Reference

Part Overview

The SEK472M016ST is a 4700 µF, 16 V aluminum electrolytic capacitor manufactured by Cornell Dubilier Electronics (CDE) in radial, can package configuration. This component is classified as Active product status and is designed for general-purpose applications requiring stable capacitance and extended operational life. The part operates across a temperature range of -55°C to 105°C with a rated lifetime of 2000 hours at 105°C.

Equivalent and substitute parts are identified when component availability is limited, supply chain disruptions occur, or design flexibility permits selection from qualified alternatives meeting identical or superior electrical and mechanical specifications.

Substitute Part Grouping Explanation

Substitution eligibility for the SEK472M016ST is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Capacitance: 4700 µF (exact match required)
• Voltage Rating: 16 V (minimum, equal or higher acceptable)
• Tolerance: ±20% (equal or tighter acceptable)
• Lifetime: 2000 Hrs @ 105°C (minimum requirement)
• Operating Temperature Range: -55°C to 105°C (minimum coverage required)
• Mounting Type: Through Hole (exact match required)
• Package / Case: Radial, Can (exact match required)
• Lead Spacing: 0.295" / 7.50 mm (exact match required)
• Size / Dimension: 0.630" Dia / 16.00 mm (exact match required)
• Regulatory Compliance: ROHS3 Compliant, REACH Unaffected (minimum required)

The ECA-1CHG472 manufactured by Panasonic Electronic Components meets all mandatory matching parameters and qualifies as a direct substitute for the SEK472M016ST.

Parameter Comparison

Engineering Selection Recommendations

Primary Part: SEK472M016ST (Cornell Dubilier Electronics)

The SEK472M016ST remains the specified component for applications where the original design parameters are maintained. This part is Active status with 921 units in stock inventory.

Qualified Substitute: ECA-1CHG472 (Panasonic Electronic Components)

The ECA-1CHG472 is a qualified direct substitute meeting all mandatory electrical and mechanical parameters. This part is Active status with 1117 units in stock inventory. The physical height difference (27.00 mm versus 32.00 mm) represents a dimensional reduction that does not affect electrical performance or circuit board layout compatibility for through-hole mounting applications with standard lead spacing.

Both parts carry ROHS3 compliance and REACH Unaffected status, satisfying regulatory requirements for equivalent component selection.

Frequently Asked Questions (FAQ)

Q: Can the ECA-1CHG472 be used as a direct replacement for the SEK472M016ST in existing designs?

A: Yes. The ECA-1CHG472 meets all mandatory electrical specifications including capacitance (4700 µF), voltage rating (16 V), tolerance (±20%), lifetime (2000 Hrs @ 105°C), and operating temperature range (-55°C to 105°C). Lead spacing and can diameter are identical. The reduced height (27.00 mm versus 32.00 mm) does not impact through-hole circuit board compatibility.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution is determined by exact matching of capacitance value, voltage rating, tolerance, lifetime rating, operating temperature range, lead spacing, can diameter, mounting type, and package configuration. Regulatory compliance status (ROHS3, REACH) must also be maintained.

Q: Does the height difference between these parts affect circuit board design?

A: No. The ECA-1CHG472 has a maximum seated height of 27.00 mm compared to 32.00 mm for the SEK472M016ST. This represents a reduction in height that does not create clearance conflicts in standard through-hole applications. PCB layout and component spacing remain compatible.

Q: Are both parts currently available?

A: Yes. The SEK472M016ST has 921 units in stock. The ECA-1CHG472 has 1117 units in stock. Both parts are Active status.

Q: What is the difference in ESR between these parts?

A: The SEK472M016ST specifies 70 mOhm ESR. The ECA-1CHG472 does not provide ESR specification in the available data. ESR is not a mandatory matching parameter for substitution eligibility.

Q: Do both parts meet the same regulatory standards?

A: Yes. Both the SEK472M016ST and ECA-1CHG472 are ROHS3 Compliant and REACH Unaffected, meeting identical regulatory requirements.
