SMP3316-152M Equivalent & Substitute Parts

Part Overview

The SMP3316-152M is a 15 µH unshielded molded inductor manufactured by Gowanda Electronics, designed for surface mount applications requiring moderate current handling. This component is classified as Active product status with 729 units in current inventory. The part operates across an industrial temperature range of -55°C to 125°C and is rated for 4.6 A continuous current with a maximum DC resistance of 41 mOhm. Equivalent and substitute parts are identified to provide design flexibility, supply chain alternatives, and component availability options for applications where the primary part may be unavailable or where design requirements permit functional substitution.

Substitute Part Grouping Explanation

Substitution eligibility for the SMP3316-152M is determined by the following critical parameters: inductance value (15 µH ±20%), unshielded configuration, surface mount capability, and nonstandard package compatibility. The substitute part SDR1005-150ML meets the core inductance specification and tolerance requirement. However, substitution analysis must account for differences in current rating, DC resistance, and operating temperature range, which may affect circuit performance in current-limited or thermally constrained applications. Both parts share identical inductance values, tolerance bands, unshielded construction, and surface mount mounting type, establishing the basis for functional equivalence in applications where the specified parameter variations are acceptable.

Engineering Selection Recommendations

The SDR1005-150ML from Bourns Inc. is qualified as a substitute for the SMP3316-152M based on matching inductance specifications and tolerance requirements. The Bourns part carries ROHS3 compliance certification, whereas the Gowanda part is not applicable for RoHS classification. Both components maintain MSL 1 rating and REACH unaffected status. Selection between these parts must account for the following parameter deviations: the SDR1005-150ML has a reduced current rating of 2.5 A compared to 4.6 A for the SMP3316-152M, a higher maximum DC resistance of 60 mOhm versus 41 mOhm, and a narrower operating temperature minimum of -40°C versus -55°C. These differences require verification against specific circuit requirements before substitution in production applications.

Frequently Asked Questions (FAQ)

Q: Can the SDR1005-150ML replace the SMP3316-152M in all applications?

A: Substitution is valid only when circuit requirements permit the parameter variations listed in the comparison table. The reduced current rating (2.5 A vs. 4.6 A) and higher DC resistance (60 mOhm vs. 41 mOhm) may impact performance in current-limited or thermally sensitive designs. The narrower temperature range (-40°C to 125°C vs. -55°C to 125°C) excludes use in applications requiring operation below -40°C.

Q: What are the key compatibility factors for these inductors?

A: Both parts share identical inductance values (15 µH ±20%), unshielded construction, surface mount mounting type, and nonstandard package classification. These matching parameters establish functional equivalence for inductance-dependent circuit functions. Differences in current handling, resistance, and temperature range must be evaluated against application specifications.

Q: Are there package or footprint considerations when substituting these parts?

A: Both components are classified as nonstandard package type. Physical dimensions differ slightly: SMP3316-152M measures 0.530" L × 0.420" W × 0.236" H (13.46mm × 10.67mm × 6.00mm), while SDR1005-150ML measures 0.500" L × 0.394" W × 0.197" H (12.70mm × 10.00mm × 5.00mm). PCB layout and thermal management considerations may be affected by these dimensional variations.

Q: What compliance certifications apply to each part?

A: The SDR1005-150ML is ROHS3 compliant. The SMP3316-152M RoHS status is not applicable. Both parts are REACH unaffected and carry EAR99 ECCN classification. Moisture sensitivity is MSL 1 (unlimited) for both components.
