Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TCK-059 is determined by the following critical parameters:

• Inductance Value: 2.2 µH ±20% tolerance
• Current Rating: Minimum 4.8 A continuous
• DC Resistance: Maximum 25mOhm (lower values acceptable)
• Operating Temperature: -40°C to 125°C minimum range
• Mounting Type: Surface Mount, Nonstandard package
• Physical Footprint: 5.80mm L x 5.20mm W (identical dimensions required)
• Regulatory Compliance: RoHS3 Compliant

The SDE0604A-2R2M from Bourns Inc. qualifies as a direct substitute based on matching inductance specification, compatible current rating (4.35 A), acceptable DC resistance (31mOhm Max), identical operating temperature range, matching surface mount configuration, and identical physical footprint dimensions.

Parameter Comparison

Engineering Selection Recommendations

Both the TCK-059 and SDE0604A-2R2M maintain Active product status with full RoHS3 compliance and REACH unaffected designation. The SDE0604A-2R2M carries AEC-Q200 automotive qualification, providing additional reliability assurance for applications requiring automotive-grade components. Selection between these parts should be based on application-specific current margin requirements and DC resistance performance specifications. The TCK-059 provides 4.8 A rating with lower DCR (25mOhm), while the SDE0604A-2R2M provides 4.35 A rating with higher DCR (31mOhm Max) but includes automotive qualification.

Frequently Asked Questions (FAQ)

Q: Can the SDE0604A-2R2M replace the TCK-059 in all applications?

A: The SDE0604A-2R2M is electrically and mechanically compatible for applications operating at or below 4.35 A continuous current. Applications requiring the full 4.8 A rating of the TCK-059 should verify that the substitute's 4.35 A rating meets system requirements.

Q: What is the impact of the 6mOhm difference in DC resistance?

A: The SDE0604A-2R2M exhibits 31mOhm maximum DC resistance compared to the TCK-059's 25mOhm. This 24% increase results in proportionally higher resistive losses. Applications sensitive to power dissipation or thermal performance should evaluate this parameter against system thermal budgets.

Q: Are the physical dimensions identical?

A: The footprint dimensions (5.80mm L x 5.20mm W) are identical. The seated height differs by 0.25mm (TCK-059: 5.05mm vs. SDE0604A-2R2M: 4.80mm), which is acceptable for standard PCB assembly clearances.

Q: What packaging differences exist between these parts?

A: The TCK-059 is supplied in Bag packaging, while the SDE0604A-2R2M is supplied in Tape & Reel (TR) format. This affects handling, storage, and automated assembly compatibility but does not impact electrical or mechanical performance.

Q: Does the SDE0604A-2R2M offer any additional certifications?

A: Yes, the SDE0604A-2R2M carries AEC-Q200 automotive qualification, which the TCK-059 does not specify. This certification is relevant for automotive and high-reliability applications.
