Substitute Part Grouping Explanation
Substitution eligibility for the VCMT053T-4R7MN5 is determined by the following critical parameters:
- Inductance value of 4.7 µH within ±20% tolerance
- Current rating equal to or greater than 4.4 A
- Saturation current (Isat) equal to or greater than 3.9 A
- DC resistance (DCR) not exceeding 59mOhm
- Surface mount package with compatible footprint dimensions (5.45 x 5.25 x 3.00 mm maximum)
- AEC-Q200 certification and ROHS3 compliance
- Operating temperature range covering -55°C to 155°C minimum
The SRP5030WA-4R7M from Bourns Inc. meets all substitution criteria with equivalent inductance, superior current handling (5.2 A vs 4.4 A), lower DC resistance (57mOhm vs 59mOhm), and extended temperature rating (-55°C to 165°C). Both parts share identical package dimensions and regulatory certifications.

Engineering Selection Recommendations
Both the VCMT053T-4R7MN5 and SRP5030WA-4R7M are Active products with full AEC-Q200 certification and ROHS3 compliance, qualifying them for automotive and industrial applications. The SRP5030WA-4R7M provides enhanced performance margins with higher current rating (5.2 A vs 4.4 A), lower DC resistance (57mOhm vs 59mOhm), and extended operating temperature range (-55°C to 165°C vs -55°C to 155°C). The substitute part incorporates shielding, which may provide electromagnetic interference mitigation benefits in sensitive circuit environments. Both components maintain identical inductance values, tolerance specifications, and package footprint compatibility within the specified dimensional tolerances.
Frequently Asked Questions (FAQ)
Q: Can the SRP5030WA-4R7M directly replace the VCMT053T-4R7MN5 on the PCB?
A: Yes. Both parts share compatible surface mount package dimensions (5.45 x 5.25 x 3.00 mm for the main part; 5.50 x 5.25 x 3.00 mm for the substitute, with 0.05 mm length variance within acceptable tolerance). The footprint compatibility is maintained for standard reflow soldering processes.
Q: What is the primary difference between these two inductors?
A: The main difference is shielding design. The VCMT053T-4R7MN5 is unshielded, while the SRP5030WA-4R7M is shielded. The substitute also provides superior electrical performance with higher current rating, lower DC resistance, and extended temperature range.
Q: Are both parts suitable for automotive applications?
A: Yes. Both parts carry AEC-Q200 certification, confirming suitability for automotive-grade applications with the required reliability and environmental stress testing.
Q: What does the ±20% inductance tolerance mean for circuit design?
A: The inductance value can vary between 3.76 µH and 5.64 µH across the production range. Circuit designs must accommodate this tolerance band to ensure proper filtering or impedance matching performance.
Q: Is the shielding on the SRP5030WA-4R7M a disadvantage?
A: No. Shielding reduces electromagnetic radiation and susceptibility to external interference, which is beneficial in most applications. It does not negatively impact performance when substituting for an unshielded part.
Q: Do both parts have the same moisture sensitivity rating?
A: Yes. Both parts are rated MSL 1 (Unlimited), indicating no moisture sensitivity concerns and no special storage or handling requirements.
