Engineering Selection Recommendations
Substitution Basis:
Both identified substitutes (74479132 and 7447915) are active Würth Elektronik components that satisfy the mandatory substitution criteria: identical manufacturer, matching 1206 (3216 Metric) package footprint, ROHS3 compliance, and identical ECCN/HTSUS classifications.
Selection Considerations:
The choice between 74479132 and 7447915 depends on circuit inductance requirements:
- 74479132 provides 470 nH inductance with 715 mA current rating and 600mOhm maximum DC resistance
- 7447915 provides 1 µH inductance with 100 mA current rating and 400mOhm maximum DC resistance
Both components operate across the -55°C to 125°C temperature range, feature unshielded multilayer construction, and carry MSL 1 (Unlimited) moisture sensitivity classification. Active product status ensures ongoing availability and supply chain continuity.
Frequently Asked Questions (FAQ)
Q: Why is the 74479136 listed as obsolete?
A: The 74479136 has reached end-of-life status within Würth Elektronik's product portfolio. Active substitutes with identical package specifications and compliance certifications are available.
Q: Can 74479132 and 7447915 be used interchangeably with 74479136?
A: Both parts meet the physical and regulatory substitution criteria (same manufacturer, package, RoHS status, ECCN, and HTSUS classification). However, circuit-level compatibility depends on the specific inductance value required by your design. The original 74479136 specifications are not provided in this reference, so inductance value must be verified against your circuit requirements.
Q: What is the difference between 74479132 and 7447915?
A: The primary differences are inductance value (470 nH vs. 1 µH), current rating (715 mA vs. 100 mA), and DC resistance (600mOhm vs. 400mOhm). Both are unshielded multilayer inductors in the 1206 package from the WE-MI series.
Q: Are both substitutes ROHS3 compliant?
A: Yes. Both 74479132 and 7447915 are ROHS3 compliant with REACH Unaffected status.
Q: What is the physical footprint compatibility?
A: Both substitutes use the 1206 (3216 Metric) package with dimensions of 0.126" L x 0.063" W (3.20mm x 1.60mm) and maximum seated height of 0.051" (1.30mm), ensuring direct PCB layout compatibility.
Q: What is the moisture sensitivity level for these components?
A: Both substitutes carry MSL 1 (Unlimited) classification, indicating no moisture sensitivity restrictions for storage or handling.
