MSS7341T-333MLD Equivalent & Substitute Parts

Part Overview

The MSS7341T-333MLD is a 33 µH shielded drum core inductor manufactured by Coilcraft, rated for 1.95 A continuous current with a maximum DC resistance of 124 mOhm. This surface mount component is designed for applications requiring fixed inductance in compact form factors and is AEC-Q200 qualified for automotive-grade reliability. The part is currently in active production status with 1049 units available in inventory.

Substitute parts are identified when equivalent inductance values, core materials, shielding characteristics, and mounting technologies align within specified electrical and mechanical tolerances, enabling direct replacement in circuit designs where the primary part becomes unavailable or when alternative sourcing is required.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MSS7341T-333MLD are qualified based on the following criteria:

Electrical Parameters (Primary Matching Criteria):

• Inductance value: 33 µH ±20% tolerance
• Core material: Ferrite shielded construction
• Shielding type: Shielded configuration
• Inductance test frequency: 100 kHz (primary specification method)

Mechanical Parameters (Secondary Matching Criteria):

• Mounting technology: Surface mount
• Physical footprint: 7.30mm x 7.30mm base dimensions
• Package classification: Nonstandard form factor
• Height compatibility: Maximum seated height within acceptable assembly clearance

Compliance & Reliability Parameters:

• AEC-Q200 automotive qualification
• RoHS3 compliance
• Operating temperature range overlap: -40°C minimum

Current Rating Consideration: Substitute parts with current ratings of 1.15 A or higher are acceptable for applications where the MSS7341T-333MLD's 1.95 A rating is specified, provided DC resistance and thermal characteristics meet circuit requirements.

Parameter Comparison

Engineering Selection Recommendations

B82472P6333M000 (EPCOS - TDK Electronics): This part qualifies as a direct substitute based on matching inductance, tolerance, core material, shielding, and footprint. The EPCOS part carries AEC-Q200 qualification and ROHS3 compliance. The current rating of 1.15 A is lower than the primary part; applications requiring the full 1.95 A rating must evaluate thermal performance and circuit current demands. DC resistance is 150 mOhm versus 124 mOhm on the primary part. Operating temperature range extends to -55°C and 150°C, providing broader environmental coverage. Packaging is Tape & Reel format with MSL 1 rating.

SRR0745A-330M (Bourns Inc.): This part qualifies as a substitute based on matching inductance, tolerance, core material, shielding, and footprint. The Bourns part carries AEC-Q200 qualification and ROHS3 compliance. The current rating of 1.35 A is lower than the primary part; circuit current requirements must be evaluated against this specification. DC resistance is 150 mOhm. Operating temperature range matches the primary part at -40°C to 125°C. Packaging is available in Cut Tape and Digi-Reel format with MSL 1 rating. Inductance test frequency is specified at 1 kHz rather than 100 kHz.

Both substitute parts maintain active production status and are suitable for applications where the MSS7341T-333MLD becomes unavailable, provided circuit current requirements do not exceed the substitute part's current rating specification.

Frequently Asked Questions (FAQ)

Q: Can B82472P6333M000 replace MSS7341T-333MLD in all applications?

A: B82472P6333M000 matches the primary part in inductance, tolerance, core material, shielding, and physical footprint. However, the current rating is 1.15 A versus 1.95 A on the primary part. Applications operating at currents above 1.15 A must evaluate whether the substitute part's thermal and saturation characteristics meet circuit requirements.

Q: What is the difference in DC resistance between these parts?

A: MSS7341T-333MLD has a maximum DC resistance of 124 mOhm. Both B82472P6333M000 and SRR0745A-330M have maximum DC resistance of 150 mOhm. This 26 mOhm difference affects power dissipation and thermal performance in the circuit.

Q: Are all three parts AEC-Q200 qualified?

A: Yes. MSS7341T-333MLD, B82472P6333M000, and SRR0745A-330M all carry AEC-Q200 automotive-grade qualification and ROHS3 compliance.

Q: Do the substitute parts fit the same PCB footprint?

A: All three parts share identical base dimensions of 7.30mm x 7.30mm. Maximum seated heights differ: MSS7341T-333MLD is 4.10mm, B82472P6333M000 is 4.50mm, and SRR0745A-330M is 4.70mm. PCB assembly clearance must accommodate the taller substitute parts.

Q: What is the difference in operating temperature range?

A: MSS7341T-333MLD and SRR0745A-330M operate from -40°C to 125°C. B82472P6333M000 extends to -55°C to 150°C, providing broader environmental coverage for extreme temperature applications.

Q: Can I use SRR0745A-330M if my circuit requires 1.95 A continuous current?

A: SRR0745A-330M is rated for 1.35 A continuous current. Applications requiring 1.95 A must use the primary part or evaluate whether the substitute part's saturation current of 1.45 A and thermal characteristics are acceptable for the specific circuit duty cycle.

Q: What packaging formats are available for these substitute parts?

A: B82472P6333M000 is supplied in Tape & Reel format. SRR0745A-330M is available in Cut Tape and Digi-Reel format. MSS7341T-333MLD packaging format is specified as nonstandard.
