Key Parameters

Substitute Part Grouping Explanation

Substitution of the LHL08NB152JS is evaluated based on the following critical parameters:

Primary Matching Criteria:

• Inductance value of 1.5 mH
• Through-hole mounting configuration
• Ferrite core material
• Unshielded construction
• ROHS3 compliance

Secondary Compatibility Factors:

• Current rating equal to or exceeding 200 mA
• DC resistance within acceptable operating limits
• Operating temperature range encompassing -25°C to 105°C
• Radial package orientation

The substitute part 1140-152K-RC from Bourns Inc. satisfies the primary matching criteria and demonstrates superior performance characteristics in current handling capacity and temperature range, making it a valid functional equivalent for the obsolete LHL08NB152JS.

Parameter Comparison

Engineering Selection Recommendations

The 1140-152K-RC from Bourns Inc. is an active product with confirmed ROHS3 compliance and REACH unaffected status, providing long-term supply chain stability compared to the obsolete LHL08NB152JS.

Electrical Compatibility: The 1140-152K-RC maintains the identical 1.5 mH inductance specification. The substitute part exceeds the current rating requirement by a factor of 14.5 (2.9 A versus 200 mA), providing design margin for current-dependent applications. The DC resistance of 0.324 Ohm is significantly lower than the 4.1 Ohm maximum of the original part, resulting in reduced power dissipation and improved efficiency in the circuit.

Environmental Compliance: Both components are ROHS3 compliant and suitable for equivalent regulatory environments. The 1140-152K-RC extends the lower operating temperature limit to -55°C, providing enhanced performance in extended temperature applications.

Physical Considerations: The 1140-152K-RC is substantially larger (1.500" diameter, 1.030" height) compared to the LHL08NB152JS (0.354" diameter, 0.374" height). PCB layout and mechanical clearance verification is required prior to implementation.

Frequently Asked Questions (FAQ)

Q: Can the 1140-152K-RC directly replace the LHL08NB152JS without circuit modification?

A: The 1140-152K-RC provides electrical equivalence at the 1.5 mH inductance specification. Physical board layout must be verified due to significant dimensional differences. The lower DC resistance and higher current rating of the substitute part are compatible with applications designed for the original component.

Q: What is the impact of the ±10% tolerance on the 1140-152K-RC compared to the ±5% tolerance of the LHL08NB152JS?

A: The 1140-152K-RC tolerance of ±10% is wider than the original ±5% specification. Applications with strict inductance tolerance requirements must evaluate whether the substitute part meets circuit performance criteria at the tolerance extremes.

Q: Are there physical mounting considerations when substituting the 1140-152K-RC?

A: Yes. The 1140-152K-RC measures 1.500" diameter and 1.030" height, compared to 0.354" diameter and 0.374" height for the LHL08NB152JS. PCB footprint, component spacing, and mechanical clearance must be assessed for the larger substitute part.

Q: Does the lower DC resistance of the 1140-152K-RC affect circuit operation?

A: The 0.324 Ohm DCR of the 1140-152K-RC is substantially lower than the 4.1 Ohm maximum of the LHL08NB152JS. This reduction decreases resistive losses and heat generation. Circuits designed for the higher resistance of the original part will experience improved efficiency with the substitute component.

Q: What is the supply status difference between these two parts?

A: The LHL08NB152JS is classified as obsolete with limited inventory availability. The 1140-152K-RC is an active product from Bourns Inc., ensuring ongoing supply chain access and long-term availability for production requirements.

Q: Are both components suitable for the same environmental and regulatory applications?

A: Both the LHL08NB152JS and 1140-152K-RC are ROHS3 compliant. The 1140-152K-RC provides extended lower temperature operation (-55°C versus -25°C), making it suitable for a broader range of environmental conditions while maintaining equivalent regulatory compliance.
