Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TLM2ADR047FTD is determined by the following critical parameters:

Electrical Equivalence Requirements:

• Resistance value: 47 mOhms
• Tolerance: ±1%
• Temperature coefficient: ±50ppm/°C
• Operating temperature range: -55°C to 155°C minimum

Mechanical Compatibility Requirements:

• Package type: 0805 (2012 Metric)
• Number of terminations: 2
• Physical dimensions: 0.079" L x 0.049" W (2.00mm x 1.25mm)

Functional Requirements:

• Composition: Metal Foil
• Application: Current Sense
• Product status: Active

Compliance Requirements:

• RoHS3 Compliant
• Moisture Sensitivity Level: MSL 1 or better

The KRL1220E-M-R047-F-T5 qualifies as a substitute part because it maintains all electrical specifications, mechanical compatibility, and functional requirements. The substitute part features an upgraded power rating (0.5W versus 0.25W), which represents a performance enhancement rather than a limitation. The substitute also includes AEC-Q200 automotive qualification, providing additional reliability certification.

Parameter Comparison

Engineering Selection Recommendations

TLM2ADR047FTD Selection Criteria:

• Primary choice for applications with strict power dissipation constraints limited to 0.25W
• Suitable for space-constrained designs where the 0.60mm maximum seated height is required
• Appropriate for general industrial applications requiring RoHS3 compliance

KRL1220E-M-R047-F-T5 Selection Criteria:

• Preferred for applications requiring higher power dissipation capability (0.5W rating)
• Mandatory selection for automotive applications requiring AEC-Q200 qualification
• Suitable for designs with thermal margin requirements or higher current sensing loads
• Compatible with applications where the 0.70mm maximum seated height is acceptable
• Maintains all electrical and mechanical compatibility with the original part

Both parts maintain Active product status, RoHS3 compliance, and MSL 1 moisture sensitivity rating. The substitute part provides enhanced reliability through automotive-grade qualification while preserving all core electrical and mechanical specifications required for current sensing applications.

Frequently Asked Questions (FAQ)

Q: Can the KRL1220E-M-R047-F-T5 be used as a direct replacement for the TLM2ADR047FTD?

A: Yes. The substitute part maintains identical resistance value (47 mOhms), tolerance (±1%), temperature coefficient (±50ppm/°C), operating temperature range (-55°C to 155°C), package type (0805), and physical dimensions (0.079" L x 0.049" W). The upgraded power rating (0.5W versus 0.25W) and AEC-Q200 qualification represent performance enhancements.

Q: What is the difference in physical height between these parts?

A: The TLM2ADR047FTD has a maximum seated height of 0.024" (0.60mm), while the KRL1220E-M-R047-F-T5 has a maximum seated height of 0.028" (0.70mm). This 0.004" (0.10mm) difference must be evaluated for applications with strict height constraints or automated assembly requirements.

Q: Are both parts suitable for current sensing applications?

A: Yes. Both parts are specified for current sensing applications and feature metal foil composition with ±1% tolerance and ±50ppm/°C temperature coefficient, which are standard requirements for precision current sensing resistors.

Q: What does AEC-Q200 qualification mean?

A: AEC-Q200 is an automotive industry standard qualification that certifies component reliability for automotive applications. The substitute part (KRL1220E-M-R047-F-T5) carries this certification, making it suitable for automotive designs, while the main part (TLM2ADR047FTD) does not carry this specific automotive qualification.

Q: Are both parts RoHS3 compliant?

A: Yes. Both the TLM2ADR047FTD and KRL1220E-M-R047-F-T5 are RoHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating, indicating no moisture sensitivity restrictions during storage or handling.

Q: Can the substitute part handle higher power dissipation?

A: Yes. The KRL1220E-M-R047-F-T5 is rated for 0.5W (1/2W) power dissipation compared to the TLM2ADR047FTD's 0.25W (1/4W) rating. This higher power rating provides additional thermal margin in current sensing applications with higher current loads.
