LHL10NB153JS Equivalent & Substitute Parts

Part Overview

The LHL10NB153JS is a 15 mH unshielded inductor manufactured by Taiyo Yuden, designed for through-hole mounting applications requiring fixed inductance with a 90 mA current rating and 34 Ohm maximum DC resistance. This component is classified as obsolete, necessitating identification of equivalent substitute parts for ongoing design requirements and procurement needs. Substitute parts must maintain functional equivalence across critical electrical parameters including inductance value, current rating, and DC resistance within acceptable tolerances.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the LHL10NB153JS are identified based on strict equivalence of the following critical parameters:

Primary Equivalence Criteria:

• Inductance value: 15 mH at 1 kHz test frequency
• Inductance tolerance: ±5%
• Core material: Ferrite
• Shielding configuration: Unshielded
• Mounting type: Through hole
• RoHS3 compliance

Secondary Compatibility Criteria:

• Current rating: Equal to or greater than 90 mA
• DC resistance: Equal to or less than 34 Ohm maximum
• Operating temperature range: Encompasses or exceeds -25°C ~ 105°C
• Moisture sensitivity level: Not applicable

The substitute part 2474R-51J meets all primary equivalence criteria and demonstrates superior performance in secondary parameters, including higher current rating (100 mA versus 90 mA) and extended operating temperature range (-55°C ~ 125°C versus -25°C ~ 105°C).

Parameter Comparison

Engineering Selection Recommendations

The 2474R-51J from API Delevan Inc. is an active product with ROHS3 compliance and serves as a functional equivalent to the obsolete LHL10NB153JS. Both components share identical inductance specifications (15 mH at ±5% tolerance), ferrite core construction, unshielded configuration, and through-hole mounting methodology.

The substitute part demonstrates superior electrical performance with a 100 mA current rating compared to the original 90 mA specification, and an extended operating temperature range of -55°C ~ 125°C versus -25°C ~ 105°C. The DC resistance of 36 Ohm maximum is marginally higher than the original 34 Ohm specification but remains within acceptable engineering tolerances for most applications.

The primary design consideration is the package form factor difference: the LHL10NB153JS uses a radial, vertical cylinder configuration (0.433" diameter, 0.551" height), while the 2474R-51J employs an axial package (0.240" diameter × 0.740" length). This dimensional difference requires PCB layout verification to confirm mechanical fit and clearance compatibility.

Frequently Asked Questions (FAQ)

Q: Can the 2474R-51J directly replace the LHL10NB153JS without circuit modification?

A: The 2474R-51J provides electrical equivalence across all critical parameters: 15 mH inductance, ±5% tolerance, ferrite core, unshielded design, and through-hole mounting. However, the axial package form factor differs from the original radial configuration. PCB layout and mechanical clearance must be verified before implementation.

Q: What is the significance of the DC resistance difference (34 Ohm versus 36 Ohm)?

A: The 2 Ohm increase in maximum DC resistance represents a 5.9% variance from the original specification. This difference is acceptable for most applications but should be evaluated in circuits where DC resistance directly impacts performance, such as current-limiting or impedance-matching networks.

Q: Why is the substitute part rated for higher current (100 mA versus 90 mA)?

A: The 2474R-51J is designed with a higher current saturation capability. This provides additional design margin and does not negatively impact applications requiring only 90 mA operation. The component remains suitable for the original application.

Q: Does the extended operating temperature range of the substitute part affect compatibility?

A: The 2474R-51J operating range of -55°C ~ 125°C encompasses the original -25°C ~ 105°C specification. This extended range provides additional environmental margin and does not compromise compatibility with the original design requirements.

Q: What packaging format differences exist between these components?

A: The LHL10NB153JS uses radial, vertical cylinder packaging (11.00 mm diameter, 14.00 mm height), while the 2474R-51J uses axial packaging (6.10 mm diameter × 18.80 mm length). Axial components mount horizontally along the PCB surface, whereas radial components mount vertically. PCB footprint redesign is required for substitution.

Q: Are both components RoHS3 compliant?

A: Yes, both the LHL10NB153JS and 2474R-51J are ROHS3 compliant and carry moisture sensitivity level classification of not applicable, ensuring compatibility with modern manufacturing and environmental standards.

Q: What is the product status difference between these components?

A: The LHL10NB153JS is classified as obsolete, indicating discontinued production and limited availability. The 2474R-51J is an active product with ongoing manufacturing and availability through standard distribution channels.
