Substitute Part Grouping Explanation

Substitution of the CM252016-101KL is determined by strict equivalence across the following critical parameters:

Inductance Value: 100 µH (exact match required)
Current Rating: 60 mA minimum
DC Resistance: 21 Ohm maximum
Core Material & Type: Ferrite, unshielded drum core
Frequency Characteristics: Q @ 796 kHz and self-resonant frequency alignment
Mounting Configuration: Surface mount technology
Physical Footprint: 2.50mm x 2.00mm base dimensions
Regulatory Compliance: ROHS3 compliance mandatory

The substitute part NLV25T-101J-PF manufactured by TDK Corporation meets these electrical and mechanical requirements, enabling direct functional replacement in applications requiring the CM252016-101KL specification.

Engineering Selection Recommendations

The NLV25T-101J-PF from TDK Corporation is a qualified substitute for the obsolete CM252016-101KL. Both components maintain ROHS3 compliance and unlimited moisture sensitivity ratings, meeting regulatory requirements for current applications.

The substitute part demonstrates superior performance characteristics in two areas: inductance tolerance (±5% versus ±10%) and operating temperature range (-40°C to 105°C versus -20°C to 100°C). These improvements provide enhanced reliability margins in temperature-sensitive applications.

Physical compatibility requires consideration of the height difference: the NLV25T-101J-PF seated height is 0.075" (1.90mm) compared to the original 0.063" (1.60mm). PCB layout and component clearance must be verified before implementation.

Both parts carry limited product status designations, indicating that long-term availability may be constrained. For new design initiatives, evaluation of current-generation inductors with equivalent electrical specifications is recommended.

Frequently Asked Questions (FAQ)

Q: Can the NLV25T-101J-PF directly replace the CM252016-101KL in existing assemblies?

A: Electrical substitution is valid based on matching inductance, current rating, DC resistance, and frequency characteristics. Physical compatibility requires verification of the 0.30mm height difference (1.90mm versus 1.60mm) against PCB layout constraints and component clearance requirements.

Q: What is the significance of the tolerance difference between ±10% and ±5%?

A: The substitute part's tighter tolerance (±5%) provides a narrower inductance variation band, resulting in improved circuit performance consistency and reduced design margin requirements in applications sensitive to inductance variation.

Q: Are both parts suitable for new product designs?

A: Both the CM252016-101KL (obsolete) and NLV25T-101J-PF (not for new designs) carry limited availability status. For new designs, current-generation inductors meeting the specified electrical parameters should be evaluated to ensure long-term supply chain stability.

Q: How do the operating temperature ranges affect application suitability?

A: The CM252016-101KL operates from -20°C to 100°C, while the NLV25T-101J-PF operates from -40°C to 105°C. The substitute part accommodates a wider temperature envelope, providing additional margin for applications with extended thermal requirements or harsh environmental conditions.

Q: What packaging formats are available for the substitute part?

A: The NLV25T-101J-PF is supplied in Cut Tape (CT) and Digi-Reel® packaging formats, supporting both manual assembly and automated reel-fed production processes.
