NLW100-16 Equivalent & Substitute Parts

Part Overview

The NLW100-16 is a 100 µF, 16 V aluminum electrolytic capacitor in axial, can package manufactured by Cornell Dubilier Electronics (CDE). This component is classified as obsolete, making identification of suitable substitute parts essential for ongoing design support and production continuity. The NLW series represents legacy technology; active alternatives with equivalent or superior electrical characteristics are available to maintain circuit functionality.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the NLW100-16 is based on the following electrical and mechanical compatibility criteria:

Primary Matching Criteria:

• Capacitance value: 100 µF (exact match required)
• Voltage rating: Minimum 16 V (equal or higher acceptable)
• Package type: Axial, can form factor (through-hole mounting)
• Polarization: Polar (aluminum electrolytic)
• Operating temperature range: Must encompass -40°C to 105°C

Secondary Compatibility Factors:

• ESR characteristics: Lower ESR values indicate improved performance
• Lifetime rating: Higher hour ratings at 105°C provide extended reliability
• Ripple current capacity: Must support application current demands
• RoHS compliance: ROHS3 compliance required for regulatory alignment

The substitute part 107TMA025M meets all primary criteria while offering improved secondary characteristics, including lower ESR, extended lifetime rating, and higher voltage margin.

Parameter Comparison

Engineering Selection Recommendations

Substitution Feasibility:

The 107TMA025M is a direct functional substitute for the NLW100-16 based on electrical equivalence and compliance status. The substitute part satisfies all mandatory electrical parameters: identical 100 µF capacitance, equal or superior voltage rating (25 V vs. 16 V), matching operating temperature range, and identical through-hole axial package configuration.

Compliance and Availability:

Both parts are ROHS3 compliant. The NLW100-16 is obsolete; the 107TMA025M is active production, ensuring long-term component availability and supply chain stability. The substitute is manufactured by Cornell Dubilier / Illinois Capacitor, maintaining manufacturer continuity.

Performance Advantages of Substitute:

The 107TMA025M provides measurable improvements: 20% lower ESR (2.653 Ohm vs. 3.3 Ohm) reduces thermal dissipation and ripple voltage; 100% longer lifetime rating (2000 Hrs vs. 1000 Hrs at 105°C) extends operational reliability; tighter tolerance (±20% vs. -10%, +75%) improves capacitance accuracy.

Physical Considerations:

The substitute is physically smaller (6.30mm x 16.00mm vs. 8.64mm x 20.57mm). Verify PCB layout and mounting hole spacing accommodate the reduced diameter and length. Through-hole lead compatibility is maintained.

Application-Specific Verification:

Confirm that the application circuit operates at or below 25 V and does not require the 150 mA low-frequency ripple current specification of the original part. The substitute is rated 120 mA @ 120 Hz; if the application demands higher low-frequency ripple current, alternative substitutes must be evaluated.

Frequently Asked Questions (FAQ)

Q: Can the 107TMA025M directly replace the NLW100-16 without circuit modification?

A: Yes, for applications operating at 16 V or below. The substitute meets all electrical specifications: identical 100 µF capacitance, equal operating temperature range (-40°C to 105°C), matching through-hole axial package, and superior voltage rating (25 V). No circuit redesign is required. Verify PCB layout accommodates the smaller physical dimensions.

Q: Why is the voltage rating higher on the substitute (25 V vs. 16 V)?

A: Higher voltage rating is a standard characteristic of the 107TMA025M series and does not negatively impact circuit performance. The capacitor will operate safely at any voltage up to its rated maximum. The 25 V rating provides additional safety margin and is common in active production aluminum electrolytic capacitors.

Q: Does the smaller physical size of the 107TMA025M affect compatibility?

A: The substitute is physically smaller (6.30mm x 16.00mm vs. 8.64mm x 20.57mm). Verify that PCB mounting holes, lead spacing, and component clearance accommodate the reduced diameter and length. The through-hole lead configuration remains compatible with standard PCB assembly processes.

Q: What is the significance of the lower ESR in the substitute part?

A: Lower ESR (2.653 Ohm vs. 3.3 Ohm) reduces resistive heating within the capacitor during ripple current operation. This results in lower internal temperature rise, improved ripple voltage performance, and extended operational life. Lower ESR is a performance advantage.

Q: The substitute has a lower ripple current rating at 120 Hz (120 mA vs. 150 mA). Is this a limitation?

A: Verify that your application circuit does not exceed 120 mA ripple current at 120 Hz. If the application requires higher low-frequency ripple current capacity, the 107TMA025M may not be suitable, and alternative substitutes must be evaluated. The substitute performs better at higher frequencies (180 mA @ 50 kHz).

Q: Why is the NLW100-16 obsolete, and what does this mean for my design?

A: Obsolete status indicates the NLW100-16 is no longer in active production. Existing inventory may be limited and subject to availability constraints. Substitution with the active-production 107TMA025M ensures long-term component availability and supply chain continuity for ongoing production and field service.

Q: Are both parts RoHS compliant?

A: Yes. Both the NLW100-16 and 107TMA025M are ROHS3 compliant, meeting environmental and regulatory requirements for restricted substance use.

Q: What is the tolerance difference, and does it matter?

A: The NLW100-16 has -10%, +75% tolerance; the 107TMA025M has ±20% tolerance. The substitute tolerance is tighter and more symmetrical, providing better capacitance accuracy and more predictable circuit performance. This is an advantage for precision applications.
