0805-151J Equivalent & Substitute Parts

Part Overview

The 0805-151J is a 150 nH unshielded drum core wirewound inductor manufactured by API Delevan Inc., rated for 400 mA with a maximum DC resistance of 560 mOhm. This component is classified as obsolete, making equivalent substitute parts necessary for new designs and production continuity. Active alternatives from major manufacturers provide direct functional replacement while maintaining electrical performance specifications.

Substitute Part Grouping Explanation

Substitute parts for the 0805-151J are selected based on strict electrical and mechanical compatibility criteria. All substitute candidates must match the following core parameters:

Inductance value: 150 nH with ±5% tolerance
Current rating: 400 mA minimum
DC resistance: 560 mOhm maximum
Shielding configuration: Unshielded
Mounting type: Surface Mount
Operating temperature range: Minimum -40°C to +125°C
Package classification: 0805 (2012 Metric) or equivalent footprint

Substitutes are grouped into two categories: direct replacements with identical DCR specifications (560 mOhm Max) and functional equivalents with slightly higher DCR (670 mOhm) that remain within acceptable operating parameters for most applications.

Engineering Selection Recommendations

All listed substitute parts are active production components with ROHS3 compliance, providing regulatory advantage over the obsolete 0805-151J. Selection among substitutes should be based on the following criteria:

Direct Electrical Match (560 mOhm DCR): AISC-0805-R15J-T, IMC0805ERR15J01, LQW2BASR15J00L, and LRW0805WJR15GG001E provide identical DC resistance specifications to the original part. These are preferred for applications where DCR tolerance is critical.

Higher DCR Alternative (670 mOhm): CW201212-R15J from Bourns offers a 110 mOhm increase in DCR. This part is suitable for applications where slightly elevated resistive losses are acceptable and where Bourns supply chain availability is advantageous.

Temperature Range Consideration: IMC0805ERR15J01 operates to +105°C maximum, which is 20°C lower than the original specification. This part should be avoided in applications requiring the full -40°C to +125°C range. LQW2BASR15J00L extends the lower temperature limit to -55°C, providing enhanced cold-temperature performance.

Core Material Variation: LQW2BASR15J00L uses an air core construction versus ceramic drum core in all other substitutes. Air core construction may exhibit different frequency response characteristics and should be evaluated for RF or high-frequency applications.

Frequently Asked Questions (FAQ)

Q: Can CW201212-R15J be used as a direct replacement despite the higher DCR specification?

A: CW201212-R15J has a DCR of 670 mOhm compared to the original 560 mOhm maximum. This 110 mOhm difference increases resistive losses by approximately 20%. Substitution is permissible only if circuit design tolerates this additional loss without exceeding thermal or performance limits.

Q: What is the difference between ceramic drum core and air core inductors?

A: LQW2BASR15J00L uses air core construction while other substitutes use ceramic drum cores. Air core inductors typically exhibit lower Q factors at lower frequencies but may provide different frequency response characteristics. Core material selection should be verified against circuit requirements.

Q: Is the IMC0805ERR15J01 suitable for applications requiring operation above 105°C?

A: No. IMC0805ERR15J01 is rated to +105°C maximum, which is 20°C below the original 0805-151J specification of +125°C. Applications requiring full temperature range operation should select alternatives with -40°C to +125°C ratings.

Q: Are all substitute parts available in the same package footprint?

A: All substitutes are classified as 0805 (2012 Metric) surface mount packages. Physical dimensions vary slightly between manufacturers. Verify PCB layout compatibility, particularly for height-constrained applications, as seated heights range from 1.40 mm to 1.55 mm.

Q: What is the significance of ROHS3 compliance for these parts?

A: All active substitute parts carry ROHS3 compliance certification, meeting current regulatory requirements for electronic components in most markets. The original 0805-151J is marked as RoHS non-compliant, making substitution necessary for new designs subject to RoHS regulations.

Q: Can these parts be used interchangeably in production?

A: Parts with identical electrical specifications (150 nH, ±5%, 400 mA, 560 mOhm DCR) are mechanically and electrically interchangeable. However, supply chain considerations, lead times, and manufacturer-specific packaging formats may require design qualification for each source.
