MALSECL00AF347CARK Equivalent & Substitute Parts

Part Overview

The MALSECL00AF347CARK is a 470 µF, 10 V aluminum electrolytic capacitor in surface mount radial can package manufactured by Vishay Beyschlag/Draloric/BC Components. This part is classified as obsolete, making equivalent substitutes necessary for ongoing production and maintenance applications. The ECL series capacitor is designed for general-purpose applications requiring stable capacitance and low equivalent series resistance in compact SMD form factors.

Substitute Part Grouping Explanation

Substitution for the MALSECL00AF347CARK is based on the following criteria:

Mandatory Matching Parameters:

Capacitance: 470 µF (exact match required)
Tolerance: ±20% (exact match required)
Package Type: Radial, Can - SMD (exact match required)
Case Size: 0.315" Dia (8.00 mm) (exact match required)
Surface Mount Land Size: 0.327" L x 0.327" W (8.30 mm x 8.30 mm) (exact match required)
Mounting Type: Surface Mount (exact match required)
Polarization: Polar (exact match required)

Allowable Parameter Variations:

Voltage Rating: Substitutes rated at 16 V are acceptable (higher voltage rating provides backward compatibility with 10 V applications)
Operating Temperature Range: Substitutes with extended lower temperature limits (-55°C) are acceptable
ESR: Variations permitted within functional requirements
Height: Minor variations acceptable within mechanical constraints
Product Status: Active parts are preferred over obsolete parts

All three substitute parts meet these criteria and are available from active manufacturers.

Engineering Selection Recommendations

All three substitute parts are manufactured by active suppliers and maintain ROHS3 compliance, ensuring regulatory continuity with the obsolete MALSECL00AF347CARK.

477AXZ016M is available in Tape & Reel packaging, suitable for high-volume automated assembly operations. This part extends the operating temperature range to -55°C and provides the lowest ESR among substitutes at 706 mOhm @ 120 Hz.

477SVH016MFE is supplied in bulk packaging and maintains the original operating temperature range of -40°C ~ 105°C. This part is specified for bypass and decoupling applications.

AHA477M16F24B-F carries AEC-Q200 automotive qualification, making it suitable for applications requiring automotive-grade reliability. This part offers the lowest seated height at 0.402" (10.20 mm) and the lowest ESR at 700 mOhm @ 120 Hz.

All substitutes are rated at 16 V, providing voltage margin above the original 10 V specification. This higher voltage rating is compatible with 10 V circuit requirements and does not introduce functional incompatibility.

Frequently Asked Questions (FAQ)

Q: Can I use a 16 V rated capacitor in place of a 10 V rated capacitor?

A: Yes. A higher voltage rating provides backward compatibility. The 16 V substitutes are suitable for 10 V applications without functional degradation.

Q: What is the significance of the different ESR values?

A: ESR (Equivalent Series Resistance) affects ripple current handling and thermal performance. The substitutes show higher ESR values measured at 120 Hz compared to the original part's 170 mOhm @ 100 kHz. Verify that ripple current specifications meet your circuit requirements before selection.

Q: Are all substitutes mechanically compatible with the original footprint?

A: Yes. All substitutes maintain the same case size (0.315" Dia / 8.00 mm), surface mount land size (0.327" L x 0.327" W / 8.30 mm x 8.30 mm), and mounting type. Height variations are minor (0.402" to 0.425") and remain within typical PCB assembly tolerances.

Q: Which substitute should I select for automotive applications?

A: The AHA477M16F24B-F carries AEC-Q200 qualification and is specified for automotive use. This part is the appropriate choice for automotive circuit requirements.

Q: What packaging options are available?

A: 477AXZ016M is supplied in Tape & Reel format for automated assembly. 477SVH016MFE is supplied in bulk packaging. Packaging selection depends on your assembly process requirements.

Q: Are all substitutes RoHS compliant?

A: Yes. All three substitute parts are ROHS3 compliant, matching the compliance status of the original MALSECL00AF347CARK.
