Substitute Part Grouping Explanation

Substitution for the obsolete Würth Elektronik 744790515 is determined by the following criteria derived from the provided specifications:

Primary Substitution Criteria:

• Package / Case: 0805 (2012 Metric) surface mount form factor
• Mounting Type: Surface Mount
• RoHS Compliance: ROHS3 Compliant
• ECCN Classification: EAR99
• HTSUS Code: 8504.50.8000
• Operating Temperature Range: -55°C ~ 125°C

Substitute Parts Identified:

1. Würth Elektronik 7447905 (MFR Recommended) - 1 µH Unshielded Multilayer Inductor, Active status
2. Würth Elektronik 74479052 (MFR Recommended) - 2.2 µH Unshielded Multilayer Inductor, Active status
3. Bourns Inc. CV201210-1R5K (Direct Manufacturer) - 1.5 µH Shielded Multilayer Inductor, Active status

All substitute parts share identical package specifications, mounting type, compliance certifications, and operating temperature ranges with the original part.

Parameter Comparison

Engineering Selection Recommendations

Selection of substitute parts for the obsolete Würth Elektronik 744790515 must be based on the following engineering criteria:

Product Status Consideration: All three substitute parts carry Active product status, ensuring long-term availability and continued manufacturer support. The original part's Obsolete status necessitates transition to an active equivalent.

Compliance and Certification: All substitute parts maintain ROHS3 compliance and EAR99 export classification, matching the original part's regulatory requirements. Moisture Sensitivity Level (MSL) rating of 1 (Unlimited) across all substitutes indicates no moisture-related handling restrictions.

Physical and Electrical Compatibility: All substitute parts utilize identical 0805 (2012 Metric) surface mount packaging with compatible height specifications (0.041" to 0.043" seated height). Operating temperature range of -55°C ~ 125°C is consistent across all options.

Inductance Value Selection: The specific inductance value of the original 744790515 is not provided in the available documentation. Selection between the three substitutes (1 µH, 1.5 µH, or 2.2 µH) must be determined by the application circuit requirements and the original design specifications.

Current Rating Considerations: Würth Elektronik 7447905 and Bourns CV201210-1R5K both support 50 mA current rating. Würth Elektronik 74479052 supports 30 mA current rating. Application current requirements determine appropriate selection.

Shielding Characteristics: Würth Elektronik substitutes (7447905 and 74479052) are unshielded multilayer inductors. Bourns CV201210-1R5K is a shielded multilayer inductor. Shielding selection depends on electromagnetic interference (EMI) considerations in the target application.

Frequently Asked Questions (FAQ)

Q: Why is the original Würth Elektronik 744790515 no longer available?

A: The part carries Obsolete product status, indicating the manufacturer has discontinued production. Substitute parts with Active status provide equivalent functionality with assured long-term availability.

Q: What determines whether a part can substitute for the 744790515?

A: Substitution is determined by matching the following parameters: 0805 (2012 Metric) surface mount package, -55°C ~ 125°C operating temperature range, ROHS3 compliance, EAR99 export classification, and HTSUS code 8504.50.8000. All three substitute parts meet these criteria.

Q: How do I select between the three substitute options?

A: Selection depends on application-specific requirements not provided in the original part documentation. The inductance value (1 µH, 1.5 µH, or 2.2 µH), current rating (30 mA or 50 mA), and shielding requirement (shielded or unshielded) must align with circuit design specifications.

Q: Are the Würth Elektronik substitutes interchangeable with the Bourns substitute?

A: All three parts share identical package dimensions, mounting type, and compliance certifications. However, the Bourns CV201210-1R5K is shielded while the Würth Elektronik options are unshielded. Shielding differences may affect electromagnetic performance in specific applications.

Q: What is the difference between the two Würth Elektronik substitute options?

A: Würth Elektronik 7447905 provides 1 µH inductance at 50 mA current rating with 400mOhm maximum DC resistance. Würth Elektronik 74479052 provides 2.2 µH inductance at 30 mA current rating with 600mOhm maximum DC resistance. Selection depends on the required inductance value and current handling capacity.

Q: Do all substitutes maintain the same moisture sensitivity level?

A: Yes. All substitute parts carry MSL rating of 1 (Unlimited), indicating no moisture-related handling or storage restrictions. This matches the moisture sensitivity profile of the original part.

Q: Are there any export or regulatory restrictions on these substitutes?

A: All substitute parts carry EAR99 export classification and ROHS3 compliance, matching the original part's regulatory status. No additional export restrictions apply beyond standard EAR99 requirements.
