MALSECA00AG333FARK Equivalent & Substitute Parts

Part Overview

The MALSECA00AG333FARK is a 330 µF, 35 V aluminum electrolytic capacitor in surface mount radial can package manufactured by Vishay Beyschlag/Draloric/BC Components. This component is classified as obsolete, making identification of equivalent and substitute parts essential for ongoing design support and production continuity. The part operates across a temperature range of -40°C to 85°C with a 2000-hour lifetime rating at 85°C, suitable for general-purpose applications requiring stable capacitance and low equivalent series resistance.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MALSECA00AG333FARK is determined by the following critical parameters:

• Capacitance value: 330 µF (exact match required)
• Voltage rating: 35 V (minimum requirement; higher ratings acceptable)
• Tolerance: ±20% (matching tolerance class)
• Package type: Radial, Can - SMD (physical and electrical compatibility)
• Polarization: Polar (electrolytic capacitor type)
• Operating temperature range: Minimum -40°C to 85°C coverage
• RoHS compliance: ROHS3 Compliant (regulatory requirement)
• Mounting type: Surface Mount (PCB assembly compatibility)

Two substitute parts meet these criteria: the 337SML035M (direct equivalent) and the 337SVH035MGE (upgraded alternative). Both are manufactured by Cornell Dubilier / Illinois Capacitor and maintain identical capacitance, voltage, tolerance, and package specifications while offering enhanced or equivalent performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

The 337SML035M serves as a direct functional equivalent to the obsolete MALSECA00AG333FARK. Both parts maintain identical electrical specifications across capacitance, voltage rating, tolerance, and ripple current handling. The 337SML035M is currently in active production status, ensuring long-term availability and supply chain stability. Minor physical height variation (10.60 mm versus 10.50 mm) and surface mount land size differences (10.00 mm x 10.00 mm versus 10.30 mm x 10.30 mm) require PCB layout verification but do not affect electrical performance.

The 337SVH035MGE represents an upgraded alternative with enhanced thermal performance. This part extends the operating temperature range to 105°C and increases the lifetime rating to 2000 hours at 105°C, compared to 85°C for the original part. The ripple current capacity increases to 410 mA at 120 Hz, providing additional margin for high-frequency applications. The 337SVH035MGE maintains identical surface mount land size (10.30 mm x 10.30 mm) to the original part, simplifying PCB compatibility. Both substitute parts carry ROHS3 compliance and unlimited moisture sensitivity rating, meeting current regulatory requirements.

Frequently Asked Questions (FAQ)

Q: Can the 337SML035M be used as a direct replacement for the MALSECA00AG333FARK?

A: Yes. The 337SML035M maintains identical electrical specifications: 330 µF capacitance, 35 V voltage rating, ±20% tolerance, 360 mA ripple current at 120 Hz, and 2000-hour lifetime at 85°C. Physical dimensions differ slightly (height 10.60 mm versus 10.50 mm; land size 10.00 mm x 10.00 mm versus 10.30 mm x 10.30 mm), requiring PCB layout verification.

Q: What is the difference between the 337SML035M and 337SVH035MGE?

A: Both parts are electrically equivalent at the rated 35 V and 330 µF specification. The 337SVH035MGE offers enhanced thermal performance with a maximum operating temperature of 105°C (versus 85°C) and a 2000-hour lifetime at 105°C (versus 85°C). The 337SVH035MGE also provides higher ripple current capacity at 410 mA versus 360 mA at 120 Hz. Surface mount land size matches the original part (10.30 mm x 10.30 mm).

Q: Are there any compliance or regulatory differences between these parts?

A: All three parts—the original MALSECA00AG333FARK and both substitutes (337SML035M and 337SVH035MGE)—are ROHS3 compliant with unlimited moisture sensitivity rating (MSL 1). No regulatory barriers exist to substitution.

Q: Which substitute should I select for a new design?

A: Selection depends on application thermal requirements. For applications operating at or below 85°C, the 337SML035M provides cost-effective equivalence. For applications requiring extended temperature operation or higher ripple current handling, the 337SVH035MGE offers superior performance margins with identical land pattern compatibility to the original part.

Q: Do the physical dimension differences affect PCB assembly?

A: The 337SML035M has a maximum height of 10.60 mm (0.1 mm taller) and different land size (10.00 mm x 10.00 mm versus 10.30 mm x 10.30 mm). The 337SVH035MGE matches the original land size (10.30 mm x 10.30 mm) with identical height (10.60 mm). PCB layout verification is required for the 337SML035M; the 337SVH035MGE requires only height clearance confirmation.
