Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the NLW100-12 is determined by the following critical parameters:

1. Capacitance Value: Must be 100 µF (±20% tolerance acceptable per IEC standards for general-purpose applications)
2. Voltage Rating: Must be ≥12 V DC; higher ratings provide derating margin
3. Polarization: Must be polar (electrolytic)
4. Package Type: Axial, Can configuration for mechanical and electrical compatibility
5. Mounting: Through-hole assembly compatibility
6. Operating Temperature Range: Must support -40°C to +105°C minimum
7. Compliance: ROHS3 compliance required for modern procurement standards

The 107TMA025M qualifies as a suitable substitute by meeting all critical substitution criteria while offering improved electrical performance characteristics.

Engineering Selection Recommendations

The 107TMA025M is the approved substitute for NLW100-12 applications. Selection rationale is based on the following factors:

Compliance and Supply: The substitute part maintains ROHS3 compliance, ensuring regulatory compatibility. The active product status guarantees continued availability and long-term procurement security, addressing the supply constraints inherent with obsolete components.

Electrical Performance: The 107TMA025M provides superior electrical characteristics, including reduced ESR (2.653 Ohm vs. 3.3 Ohm @ 120 Hz) and doubled operational lifetime (2000 Hrs vs. 1000 Hrs @ 105°C). The higher voltage rating (25 V vs. 12 V) provides additional derating margin in the application circuit.

Physical Compatibility: Both parts employ identical axial can package geometry and through-hole mounting methodology. The substitute part's smaller physical dimensions (6.30 mm x 16.00 mm vs. 8.13 mm x 20.57 mm) provide design flexibility without compromising electrical substitution criteria.

Tolerance Specification: The 107TMA025M's tighter tolerance (±20%) improves circuit predictability compared to the original part's asymmetrical tolerance range (-10%, +75%).

Frequently Asked Questions (FAQ)

Q: Can the 107TMA025M be used directly as a drop-in replacement for NLW100-12? A: Yes. Both parts feature identical capacitance (100 µF), matching axial can package configuration, and through-hole mounting compatibility. The higher voltage rating (25 V) is advantageous for circuit derating.

Q: What are the key differences between these parts? A: The substitute offers higher voltage rating (25 V vs. 12 V), lower ESR (2.653 vs. 3.3 Ohm), doubled operational lifetime (2000 vs. 1000 Hrs @ 105°C), and tighter tolerance specification (±20% vs. -10%, +75%). Physical size is also reduced.

Q: Is the smaller physical size of the 107TMA025M a concern? A: No. The smaller dimensions (6.30 mm x 16.00 mm vs. 8.13 mm x 20.57 mm) provide design flexibility. Axial lead spacing remains compatible with standard through-hole PCB layouts.

Q: Are ripple current ratings equivalent? A: The ripple current specifications differ between measurement frequencies. The NLW100-12 is rated 150 mA @ 120 Hz and 172.5 mA @ 10 kHz. The 107TMA025M provides 120 mA @ 120 Hz and 180 mA @ 50 kHz. Application-specific frequency analysis determines suitability.

Q: Does the substitute meet regulatory requirements? A: Yes. The 107TMA025M carries ROHS3 Compliant certification, maintaining regulatory alignment with the original component specification.

Q: Why is the NLW100-12 listed as obsolete? A: Product obsolescence reflects manufacturing discontinuation. The active status of the 107TMA025M ensures reliable long-term component availability for equivalent functionality.
