Equivalent & Substitute Parts for 337AVD016MFE

Part Overview

The 337AVD016MFE is a 330 µF, 16 V aluminum electrolytic capacitor in surface mount radial can package manufactured by Cornell Dubilier / Illinois Capacitor. This component is classified as obsolete, indicating discontinuation from active production. The part is designed for general purpose applications requiring energy storage and filtering in low-voltage circuits. Due to its obsolete status, identification of functionally equivalent substitute components is necessary to support ongoing maintenance, repair, and new design requirements where legacy specifications must be maintained.

Substitute Part Grouping Explanation

Substitution of the 337AVD016MFE is determined by strict equivalence across the following critical parameters:

Primary Equivalence Criteria:

• Capacitance value: 330 µF (exact match required)
• Voltage rating: 16 V (exact match required)
• Tolerance: ±20% (exact match required)
• Polarization: Polar (exact match required)
• Package type: Radial, Can - SMD (exact match required)
• Mounting type: Surface Mount (exact match required)
• Operating temperature range: -55°C ~ 105°C (exact match required)
• Lifetime rating: 5000 Hrs @ 105°C (exact match required)

Secondary Compatibility Parameters:

• Physical dimensions (diameter and height within acceptable PCB layout tolerances)
• Surface mount land size (within acceptable reflow soldering tolerances)
• Moisture sensitivity level: 1 (Unlimited)
• Regulatory compliance (REACH, ECCN, HTSUS classification)

The ATB337M016 meets all primary equivalence criteria and is therefore classified as a direct substitute for the 337AVD016MFE.

Parameter Comparison

Engineering Selection Recommendations

The ATB337M016 is the direct substitute for the obsolete 337AVD016MFE. Both components are manufactured by Cornell Dubilier / Illinois Capacitor and share identical electrical specifications for capacitance, voltage rating, tolerance, operating temperature range, and lifetime rating.

The ATB337M016 offers the following advantages:

Product Status: The ATB337M016 maintains active production status, ensuring long-term availability and supply chain continuity compared to the discontinued 337AVD016MFE.

Regulatory Compliance: The ATB337M016 is RoHS3 compliant, providing enhanced environmental and regulatory alignment for new designs and manufacturing processes.

Performance Characteristics: The ATB337M016 demonstrates improved electrical performance with lower ESR (760 mOhm versus 1 Ohm at 120 Hz) and higher ripple current capability at low frequency (420 mA versus 300 mA at 120 Hz), while maintaining identical high-frequency ripple current performance (600 mA at 100 kHz).

Physical Compatibility: The ATB337M016 maintains equivalent physical dimensions (0.315" diameter, 10.50mm height) with minimal variation in surface mount land size (8.30mm x 8.60mm versus 8.30mm x 8.30mm), ensuring compatibility with existing PCB layouts designed for the 337AVD016MFE.

Frequently Asked Questions (FAQ)

Q: Can the ATB337M016 be used as a direct replacement for the 337AVD016MFE in existing designs?

A: Yes. The ATB337M016 meets all primary equivalence criteria including capacitance (330 µF), voltage rating (16 V), tolerance (±20%), operating temperature range (-55°C ~ 105°C), and lifetime rating (5000 Hrs @ 105°C). Physical dimensions are compatible with PCB layouts designed for the 337AVD016MFE.

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

A: The 337AVD016MFE has an ESR of 1 Ohm at 120 Hz, while the ATB337M016 has an ESR of 760 mOhm at 120 Hz. The lower ESR of the ATB337M016 represents improved performance characteristics in the substitute component.

Q: Are there any compliance differences between the 337AVD016MFE and ATB337M016?

A: The ATB337M016 is RoHS3 compliant, whereas the 337AVD016MFE does not specify RoHS compliance. Both components are REACH unaffected and share identical ECCN (EAR99) and HTSUS (8532.22.0020) classifications.

Q: Will the ATB337M016 fit the same PCB footprint as the 337AVD016MFE?

A: The components share the same diameter (0.315" / 8.00mm) and nearly identical heights (10.60mm versus 10.50mm). Surface mount land sizes are compatible (8.30mm x 8.30mm versus 8.30mm x 8.60mm), allowing use in existing PCB designs with standard reflow soldering processes.

Q: What is the ripple current rating difference?

A: At 120 Hz, the ATB337M016 supports 420 mA ripple current compared to 300 mA for the 337AVD016MFE. At 100 kHz, both components support identical ripple current of 600 mA. The higher low-frequency ripple current capability of the ATB337M016 provides additional design margin.

Q: Why is the 337AVD016MFE classified as obsolete?

A: The 337AVD016MFE has been discontinued from active production by Cornell Dubilier / Illinois Capacitor. The ATB337M016 represents the active production equivalent that maintains functional and electrical compatibility while offering improved performance and regulatory compliance.
