Key Parameters

Substitute Part Grouping Explanation

Substitution of the TLM2BDR022FTD is permissible when the alternative component maintains the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 22 mOhms (0.022 Ohm)
• Tolerance: ±1%
• Composition: Metal Foil
• Temperature Coefficient: ±50 ppm/°C
• Operating Temperature Range: -55°C to 155°C
• Package / Case: 1206 (3216 Metric)
• Number of Terminations: 2
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Allowable Variation Parameters:

• Power Rating: Equal to or greater than 0.5W
• Physical dimensions: Within standard 1206 package tolerances
• Certifications: Additional qualifications (such as AEC-Q200) are permissible

The substitute part KRL1632E-M-R022-F-T5 satisfies all mandatory parameters and provides an increased power rating of 0.75W (3/4W), making it suitable for applications requiring higher power dissipation capability.

Parameter Comparison

Engineering Selection Recommendations

Primary Part Selection (TLM2BDR022FTD): Select the TLM2BDR022FTD when the application requires a 0.5W (1/2W) rated current sense resistor with standard industrial compliance. This part is Active status and ROHS3 compliant, suitable for general industrial and consumer applications operating within the -55°C to 155°C temperature range.

Substitute Part Selection (KRL1632E-M-R022-F-T5): Select the KRL1632E-M-R022-F-T5 when the application requires:

• Higher power dissipation capability (0.75W versus 0.5W)
• Automotive-grade qualification (AEC-Q200 certified)
• Defined REACH compliance status
• Extended inventory availability

Both parts maintain identical electrical characteristics (22 mOhms ±1%, ±50 ppm/°C temperature coefficient) and are compatible with 1206 package footprints. The substitute part provides enhanced thermal performance and automotive qualification without compromising electrical performance or compliance requirements.

Frequently Asked Questions (FAQ)

Q: Can KRL1632E-M-R022-F-T5 be used as a direct replacement for TLM2BDR022FTD?

A: Yes. Both components share identical resistance (22 mOhms ±1%), tolerance, temperature coefficient (±50 ppm/°C), operating temperature range (-55°C to 155°C), package type (1206), and compliance status (ROHS3). The substitute part has a higher power rating (0.75W versus 0.5W), which is compatible with applications designed for the original 0.5W part.

Q: Are there physical footprint differences between these parts?

A: Both parts use the 1206 (3216 Metric) package. The TLM2BDR022FTD measures 0.120" L x 0.061" W (3.05mm x 1.55mm), while the KRL1632E-M-R022-F-T5 measures 0.126" L x 0.063" W (3.20mm x 1.60mm). These dimensions fall within standard 1206 package tolerances and are compatible with identical PCB footprints.

Q: What is the significance of the AEC-Q200 qualification on the substitute part?

A: AEC-Q200 is an automotive industry qualification standard. The KRL1632E-M-R022-F-T5 carries this certification, making it suitable for automotive applications. If the original application does not require automotive qualification, this additional certification does not affect compatibility.

Q: Do both parts have the same moisture sensitivity level?

A: Yes. Both the TLM2BDR022FTD and KRL1632E-M-R022-F-T5 have Moisture Sensitivity Level 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.

Q: What is the difference in REACH compliance status?

A: The TLM2BDR022FTD has Vendor Undefined REACH status, while the KRL1632E-M-R022-F-T5 has REACH Unaffected status. REACH Unaffected indicates the component is not subject to REACH restrictions. For applications requiring defined REACH compliance documentation, the substitute part provides explicit compliance status.

Q: Can the higher power rating of the substitute part cause issues in the original circuit?

A: No. A component with a higher power rating (0.75W) can be used in applications designed for a lower power rating (0.5W). The higher rating provides additional thermal margin and does not affect electrical performance or circuit operation.

Q: Are the temperature coefficients identical?

A: Yes. Both parts have a temperature coefficient of ±50 ppm/°C and operate across the identical temperature range of -55°C to 155°C, ensuring equivalent thermal performance characteristics.
