Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SPD74R-104M are qualified based on the following critical parameters:

• Inductance value of 100 µH within ±20% tolerance
• Shielded drum core wirewound construction with ferrite core material
• Surface mount nonstandard package configuration
• Saturation current rating sufficient for application requirements
• DC resistance within acceptable operating limits
• ROHS3 compliance and equivalent environmental ratings
• Operating temperature range compatibility

The VLS5045EX-101M-H from TDK Corporation meets these substitution criteria while maintaining functional equivalence for the 100 µH inductance specification.

Parameter Comparison

Engineering Selection Recommendations

Both the SPD74R-104M and VLS5045EX-101M-H are active production components with ROHS3 compliance and equivalent moisture sensitivity ratings. The SPD74R-104M provides a higher continuous current rating of 860 mA compared to the VLS5045EX-101M-H at 700 mA. The VLS5045EX-101M-H carries AEC-Q200 automotive qualification. Selection between these parts depends on application current requirements and temperature range constraints. The SPD74R-104M supports the extended lower temperature limit of -55°C, while the VLS5045EX-101M-H operates from -40°C minimum. Both components maintain the required 100 µH inductance specification and shielded ferrite core construction.

Frequently Asked Questions (FAQ)

Q: Can the VLS5045EX-101M-H replace the SPD74R-104M in all applications?

A: The VLS5045EX-101M-H is suitable as a substitute when the application current requirement does not exceed 700 mA and the operating temperature range remains above -40°C. If the circuit requires the full 860 mA rating or operates below -40°C, the SPD74R-104M is the appropriate choice.

Q: What are the physical dimension differences between these parts?

A: The SPD74R-104M measures 0.287" L x 0.287" W x 0.185" H (7.30mm x 7.30mm x 4.70mm). The VLS5045EX-101M-H measures 0.209" L x 0.197" W x 0.177" H (5.30mm x 5.00mm x 4.50mm). Both are nonstandard packages and physical compatibility must be verified for the specific application layout.

Q: Are there differences in DC resistance between these inductors?

A: Yes. The SPD74R-104M has a maximum DC resistance of 610 mOhm, while the VLS5045EX-101M-H has a maximum of 754 mOhm. Applications sensitive to resistive losses should account for this 144 mOhm difference in circuit calculations.

Q: Do both parts meet the same compliance standards?

A: Both the SPD74R-104M and VLS5045EX-101M-H are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity ratings. The VLS5045EX-101M-H additionally carries AEC-Q200 automotive qualification.

Q: What inductance tolerance applies to both parts?

A: Both the SPD74R-104M and VLS5045EX-101M-H are specified with ±20% inductance tolerance at their respective test frequencies.
