NLW75-16 Equivalent & Substitute Parts

Part Overview

The NLW75-16 is a 75 µF, 16 V aluminum electrolytic capacitor in axial, can package manufactured by Cornell Dubilier Electronics (CDE). This component is classified as obsolete, indicating discontinued production and limited availability for new designs. The part operates across a temperature range of -40°C to 105°C with a rated lifetime of 1000 hours at 105°C, suitable for general-purpose applications requiring through-hole mounting.

Identification of equivalent and substitute parts is necessary due to the obsolete status of the NLW75-16. Substitute components must maintain functional compatibility within the electrical and mechanical constraints of the original application while offering improved availability and potentially enhanced performance characteristics.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the NLW75-16 is determined by the following critical parameters:

Electrical Compatibility Criteria:

• Capacitance value must equal or exceed 75 µF
• Voltage rating must be equal to or greater than 16 V
• ESR must be equal to or lower than 4.5 Ohm @ 120 Hz to maintain ripple current performance
• Operating temperature range must encompass -40°C to 105°C
• Lifetime rating must meet or exceed 1000 hours @ 105°C

Mechanical Compatibility Criteria:

• Package type must be Axial, Can
• Mounting type must be Through Hole
• Polarization must remain Polar

Compliance Criteria:

• RoHS3 compliance required
• MSL rating of 1 (Unlimited) acceptable

The substitute part 107TMA025M meets these substitution criteria through higher capacitance (100 µF), elevated voltage rating (25 V), reduced ESR (2.653 Ohm @ 120 Hz), extended lifetime (2000 Hrs @ 105°C), and active product status with improved availability.

Parameter Comparison

Engineering Selection Recommendations

The 107TMA025M is a direct substitute for the NLW75-16 based on the following engineering factors:

Product Status Advantage: The 107TMA025M holds active product status, ensuring continued manufacturing and supply chain availability, whereas the NLW75-16 is obsolete and subject to inventory depletion.

Electrical Performance Enhancement: The substitute part provides superior electrical characteristics: increased capacitance (100 µF vs. 75 µF), higher voltage rating (25 V vs. 16 V), and significantly reduced ESR (2.653 Ohm vs. 4.5 Ohm @ 120 Hz). These improvements result in lower heat dissipation and enhanced ripple current handling at high frequencies (180 mA @ 50 kHz vs. 156.4 mA @ 10 kHz).

Reliability Improvement: The 107TMA025M offers doubled lifetime rating (2000 Hrs @ 105°C vs. 1000 Hrs @ 105°C), extending component service life in thermal stress conditions.

Compliance Alignment: Both components maintain ROHS3 compliance, EAR99 export classification, and identical HTSUS coding, ensuring regulatory and procurement consistency.

Physical Compatibility: Both components utilize identical through-hole axial can packaging with polar configuration. The substitute part features a smaller physical footprint (0.248" Dia x 0.630" L vs. 0.340" Dia x 0.810" L), providing layout flexibility without compromising electrical performance.

Frequently Asked Questions (FAQ)

Q: Can the 107TMA025M directly replace the NLW75-16 in existing circuit designs?

A: Yes. The 107TMA025M meets all electrical and mechanical substitution criteria. The higher capacitance (100 µF vs. 75 µF) and voltage rating (25 V vs. 16 V) provide operational margin. The reduced ESR improves performance. Both components share identical through-hole axial can packaging and polar configuration.

Q: What is the significance of the capacitance difference between 75 µF and 100 µF?

A: The 100 µF capacitance of the substitute part exceeds the original 75 µF specification. In general-purpose applications, increased capacitance provides enhanced energy storage and improved voltage regulation without adverse effects. Circuit design must confirm that the higher capacitance does not introduce unintended behavior in timing-sensitive or frequency-dependent applications.

Q: How does the voltage rating difference affect substitution?

A: The 107TMA025M operates at 25 V rated voltage compared to the NLW75-16 at 16 V. A higher voltage rating provides increased safety margin and stress reduction on the dielectric material, extending component reliability. The substitute part is suitable for all applications rated at 16 V or lower.

Q: What is the impact of ESR reduction from 4.5 Ohm to 2.653 Ohm?

A: Lower ESR reduces resistive losses and heat generation during ripple current operation. The 107TMA025M dissipates less power and operates at lower temperatures under identical ripple current conditions, contributing to improved reliability and extended operational life.

Q: Are there physical installation considerations due to size differences?

A: The 107TMA025M is physically smaller (0.248" Dia x 0.630" L vs. 0.340" Dia x 0.810" L). This reduction in footprint may provide layout advantages on printed circuit boards. Both components use identical through-hole mounting, requiring no modification to existing PCB hole patterns or lead spacing.

Q: Does the tolerance difference (-10%, +75% vs. ±20%) affect circuit performance?

A: The 107TMA025M features tighter tolerance (±20%) compared to the NLW75-16 (-10%, +75%). Tighter tolerance provides more predictable capacitance values and improved circuit performance consistency. This represents an enhancement over the original part specification.

Q: What is the significance of the doubled lifetime rating?

A: The 107TMA025M provides 2000 hours @ 105°C lifetime versus 1000 hours for the NLW75-16. Extended lifetime indicates improved thermal stability and reduced degradation rates, resulting in longer service intervals and reduced maintenance requirements in high-temperature operating environments.

Q: Are both components RoHS3 compliant?

A: Yes. Both the NLW75-16 and 107TMA025M maintain ROHS3 compliance, ensuring compatibility with environmental and regulatory requirements for electronic component procurement and assembly.
