Inductance tolerance of ±20 percent
Current rating equal to or greater than 4.5 A
Saturation current (Isat) equal to or greater than 5 A
DC resistance (DCR) at or below 36.4 mOhm maximum

Mechanical Compatibility Criteria:

Shielded drum core wirewound construction
Surface mount nonstandard package configuration
Physical dimensions compatible with 5.50 mm × 5.00 mm footprint tolerance
Height (seated) at or below 3.00 mm maximum
Operating temperature range of -40°C to 125°C

Compliance and Certification Criteria:

RoHS3 compliance status
Moisture sensitivity level MSL 1 (Unlimited)
Active product status

The SRP5030T-2R2M from Bourns Inc. meets all substitution criteria and is classified as a direct equivalent part.

Engineering Selection Recommendations

Primary Part Selection: The MPLCG0530L2R2 remains the specified component when design requirements explicitly call for metal composite core material or when the exact 5.50 mm × 5.00 mm footprint is a critical constraint. This part maintains active product status with confirmed inventory availability of 2085 pieces.

Substitute Part Selection: The SRP5030T-2R2M from Bourns Inc. is a qualified substitute when the MPLCG0530L2R2 becomes unavailable or when higher current and saturation ratings provide design margin benefits. The substitute offers superior DC resistance performance (35 mOhm versus 36.4 mOhm maximum) and higher current handling capability (5.5 A versus 4.5 A). The iron powder core material provides equivalent functional performance within the specified inductance tolerance and frequency test conditions.

Compliance Verification: Both parts maintain identical RoHS3 compliance status, moisture sensitivity level MSL 1 (Unlimited), and operating temperature range (-40°C to 125°C). Both are packaged in Tape & Reel format suitable for automated assembly processes. Substitution does not compromise regulatory or environmental compliance requirements.

Dimensional Considerations: The SRP5030T-2R2M footprint (5.70 mm × 5.20 mm) is marginally larger than the MPLCG0530L2R2 (5.50 mm × 5.00 mm). PCB layout verification is required to confirm that the 0.20 mm length and 0.20 mm width increase does not conflict with board routing or component placement constraints. Height remains identical at 3.00 mm maximum.

Frequently Asked Questions (FAQ)

Q: Can the SRP5030T-2R2M be used as a direct replacement for the MPLCG0530L2R2 in all applications?

A: The SRP5030T-2R2M meets all electrical and mechanical substitution criteria for the MPLCG0530L2R2. However, PCB layout verification is required due to the 0.20 mm increase in both length and width dimensions. Confirm that the slightly larger footprint does not conflict with existing board routing or adjacent component placement before implementation.

Q: What is the difference between the metal composite core in the MPLCG0530L2R2 and the iron powder core in the SRP5030T-2R2M?

A: Both core materials are designed to achieve the same 2.2 µH inductance value at 100 kHz test frequency within ±20 percent tolerance. The core material difference does not affect electrical performance within the specified parameters. The iron powder core in the substitute part delivers lower DC resistance (35 mOhm versus 36.4 mOhm maximum), providing superior thermal performance.

Q: Are there any compliance or certification differences between these two parts?

A: Both the MPLCG0530L2R2 and SRP5030T-2R2M maintain identical RoHS3 compliance status, moisture sensitivity level MSL 1 (Unlimited), and operating temperature range (-40°C to 125°C). No compliance or certification differences exist between the two parts.

Q: What are the current rating differences, and do they affect substitution suitability?

A: The MPLCG0530L2R2 is rated for 4.5 A continuous current with 5 A saturation current. The SRP5030T-2R2M is rated for 5.5 A continuous current with 9 A saturation current. The substitute part's higher ratings provide additional design margin and thermal headroom. Substitution is suitable for applications operating at or below the original 4.5 A specification.

Q: How do the DC resistance specifications compare?

A: The MPLCG0530L2R2 specifies a maximum DC resistance of 36.4 mOhm, while the SRP5030T-2R2M specifies a maximum of 35 mOhm. The substitute part offers lower DC resistance, resulting in reduced resistive losses and improved thermal performance. This represents a performance advantage for the substitute part.

Q: Is packaging format identical between the two parts?

A: Both the MPLCG0530L2R2 and SRP5030T-2R2M are supplied in Tape & Reel (TR) packaging format, suitable for automated pick-and-place assembly processes. No packaging format differences exist.

Q: What inventory status should be considered when selecting between these parts?

A: The MPLCG0530L2R2 has confirmed inventory of 2085 pieces in stock. The SRP5030T-2R2M has confirmed inventory of 8073 pieces in stock. Inventory availability may influence procurement decisions based on project timeline and supply chain requirements.
