Substitute Part Grouping Explanation

Substitution of the TLM2BDR082FTD with the KRL1632E-M-R082-F-T5 is permissible based on the following criteria:

Matching Parameters:

• Resistance value: 0.082 Ohm (82 mOhms)
• Tolerance: ±1%
• Composition: Metal Foil
• Package / Case: 1206 (3216 Metric)
• Temperature Coefficient: ±50ppm/°C
• Operating Temperature Range: -55°C to 155°C
• Number of Terminations: 2
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Differentiating Parameter:

• Power Rating: The substitute part (KRL1632E-M-R082-F-T5) is rated for 0.75W (3/4W), which exceeds the 0.5W (1/2W) rating of the main part. This represents an upgrade in power dissipation capability.

The substitute part is qualified to AEC-Q200 automotive standards, providing additional qualification beyond the main part specification.

Parameter Comparison

Engineering Selection Recommendations

Both the TLM2BDR082FTD and KRL1632E-M-R082-F-T5 are active production components with ROHS3 compliance and identical electrical specifications for resistance, tolerance, and temperature coefficient. The primary distinction is the power rating differential and automotive qualification status.

Selection of the TLM2BDR082FTD is appropriate for applications requiring a 0.5W (1/2W) rated current sense resistor in 1206 package format with standard industrial compliance.

Selection of the KRL1632E-M-R082-F-T5 is appropriate for applications requiring enhanced power dissipation capability (0.75W / 3/4W) or automotive-grade qualification per AEC-Q200 standards. The higher power rating provides additional thermal margin in current sensing circuits. The automotive qualification makes this part suitable for automotive and harsh environment applications.

Both parts maintain identical package dimensions, termination count, and operating temperature range, ensuring mechanical and thermal compatibility in PCB layouts designed for 1206 (3216 Metric) form factor components.

Frequently Asked Questions (FAQ)

Q: Can the KRL1632E-M-R082-F-T5 be used as a direct replacement for the TLM2BDR082FTD?

A: Yes. Both parts share identical resistance value (0.082 Ohm), tolerance (±1%), composition (Metal Foil), package format (1206 / 3216 Metric), temperature coefficient (±50ppm/°C), and operating temperature range (-55°C to 155°C). The substitute part features a higher power rating (0.75W versus 0.5W) and AEC-Q200 automotive qualification, making it suitable for direct substitution in applications where these attributes are beneficial or required.

Q: What is the significance of the power rating difference between these parts?

A: The TLM2BDR082FTD is rated for 0.5W (1/2W) power dissipation, while the KRL1632E-M-R082-F-T5 is rated for 0.75W (3/4W). In current sensing applications, the power rating determines the maximum continuous current the resistor can safely dissipate without exceeding temperature limits. The higher power rating of the substitute part provides additional thermal headroom and allows operation at higher current levels before thermal derating becomes necessary.

Q: Are the physical dimensions compatible between these parts?

A: Both parts are packaged in 1206 (3216 Metric) form factor. The TLM2BDR082FTD has dimensions of 0.120" L x 0.061" W (3.05mm x 1.55mm) with a maximum seated height of 0.028" (0.70mm). The KRL1632E-M-R082-F-T5 has dimensions of 0.126" L x 0.063" W (3.20mm x 1.60mm) with an identical maximum seated height of 0.028" (0.70mm). These minor dimensional variations are within standard 1206 package tolerances and do not affect PCB layout compatibility.

Q: What does AEC-Q200 qualification mean?

A: AEC-Q200 is an automotive industry standard qualification that certifies passive components for use in automotive applications. The KRL1632E-M-R082-F-T5 carries this qualification, indicating it meets stringent automotive reliability, temperature cycling, and performance requirements. This qualification is not specified for the TLM2BDR082FTD.

Q: Are both parts RoHS compliant?

A: Yes. Both the TLM2BDR082FTD and KRL1632E-M-R082-F-T5 are ROHS3 compliant and have a Moisture Sensitivity Level (MSL) of 1 (Unlimited), indicating no moisture sensitivity restrictions during storage and handling.

Q: Can these parts be used interchangeably in current sensing circuits?

A: Yes. Both parts are metal foil composition current sense resistors with identical resistance, tolerance, and temperature coefficient specifications. They are mechanically and electrically compatible for use in current sensing applications. The substitute part's higher power rating and automotive qualification provide additional capability without compromising circuit performance.
