Key Parameters

Substitute Part Grouping Explanation

The 337TMA035M qualifies as a substitute based on the following alignment criteria:

Matching parameters: 330 µF capacitance, ±20% tolerance, axial can package, through-hole mounting, and polar configuration. The substitute maintains identical capacitance and tolerance specifications, ensuring functional equivalence in the primary electrical characteristic.

Voltage rating consideration: The substitute operates at 35 V, exceeding the original 16 V specification. This represents an uprating that is electrically compatible for applications designed for 16 V operation, as the component can safely operate at lower voltages than its rated maximum.

Physical compatibility: Both components use axial, can-style packaging with through-hole mounting, confirming mechanical interchangeability in standard PCB layouts.

Parameter Comparison

Engineering Selection Recommendations

The 337TMA035M is available as an active product with current manufacturing status and ROHS3 compliance, addressing the obsolescence of the MAL212385331. The substitute maintains electrical equivalence through matching capacitance and tolerance specifications.

Designers should evaluate application-specific requirements regarding operating temperature range and ripple current capacity. The substitute operates within -40°C to 105°C, compared to the original -55°C to 125°C range. The substitute's ripple current rating of 330 mA at 120 Hz is lower than the original 510 mA at 100 Hz specification.

The higher voltage rating of the substitute (35 V versus 16 V) presents no electrical incompatibility for circuits designed for 16 V operation. The improved ESR of the substitute (703 mOhm versus 1 Ohm) offers performance benefits in filtering and decoupling applications.

Frequently Asked Questions (FAQ)

Q: Can the 337TMA035M directly replace the MAL212385331 in all applications?

A: Electrical substitution is valid based on matching capacitance (330 µF) and tolerance (±20%). Physical compatibility is confirmed through identical axial can packaging and through-hole mounting. Application-specific evaluation is required for circuits operating at temperature extremes below -40°C or above 105°C, or requiring ripple current exceeding 330 mA at 120 Hz.

Q: What is the significance of the voltage rating difference?

A: The substitute's 35 V rating exceeds the original 16 V specification. Aluminum electrolytic capacitors operate safely at voltages below their rated maximum. No derating or circuit modification is required when substituting a higher-voltage-rated component in a 16 V application.

Q: Are there physical dimension differences between these components?

A: The MAL212385331 measures 0.406" diameter by 1.260" length (10.30mm x 32.00mm). The 337TMA035M measures 0.394" diameter by 0.827" length (10.00mm x 21.00mm). Both use axial can packaging with through-hole leads, confirming mechanical interchangeability in standard PCB layouts.

Q: How do the ESR specifications compare?

A: The MAL212385331 specifies 1 Ohm ESR at 100 Hz. The 337TMA035M specifies 703 mOhm ESR at 120 Hz. The lower ESR of the substitute indicates improved performance in filtering and decoupling applications, with reduced impedance at operating frequencies.

Q: What compliance differences exist between these parts?

A: The MAL212385331 is RoHS non-compliant. The 337TMA035M is ROHS3 compliant, meeting current environmental and regulatory requirements for new designs and procurement.
