TLM2ADR082FTD Equivalent & Substitute Parts

Part Overview

The TLM2ADR082FTD is a 0.082 ohm (82 mOhms) metal foil chip resistor manufactured by TE Connectivity Passive Product. This component is rated for 0.25W (1/4W) power dissipation with ±1% tolerance and is designed for current sensing applications. The part is packaged in 0805 (2012 Metric) form factor and operates across the temperature range of -55°C to 155°C. The component maintains Active product status and is RoHS3 compliant with unlimited moisture sensitivity rating (MSL 1). Equivalent and substitute parts are identified to provide alternative sourcing options when the primary part is unavailable or when design requirements necessitate enhanced specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TLM2ADR082FTD is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 0.082 Ohm (82 mOhms)
• Tolerance: ±1%
• Composition: Metal Foil
• Package / Case: 0805 (2012 Metric)
• Temperature Coefficient: ±50ppm/°C
• Operating Temperature Range: -55°C to 155°C
• Features: Current Sense application capability
• Compliance: RoHS3 Compliant, REACH Unaffected

Allowable Variation Parameters:

• Power Rating: Substitute parts may exceed the 0.25W specification, provided all other parameters remain equivalent. Higher power ratings do not compromise functionality in applications requiring the base specification.
• Physical Height: Minor variations in seated height are acceptable within standard manufacturing tolerances for the 0805 package form factor.
• Certifications: Additional automotive or industrial certifications (such as AEC-Q200) may be present in substitute parts without affecting compatibility.

The substitute part KRL1220E-M-R082-F-T5 meets all mandatory matching parameters and includes an enhanced power rating of 0.5W (1/2W) with AEC-Q200 automotive qualification.

Engineering Selection Recommendations

Primary Part Selection (TLM2ADR082FTD): The TLM2ADR082FTD is the specified component for applications requiring a 0.082 ohm metal foil current sense resistor in 0805 package format with 0.25W power rating. This part is Active in product status and maintains full RoHS3 compliance with unlimited moisture sensitivity rating.

Substitute Part Selection (KRL1220E-M-R082-F-T5): The KRL1220E-M-R082-F-T5 from Susumu is a direct functional equivalent with identical electrical specifications (0.082 ohm, ±1% tolerance, ±50ppm/°C temperature coefficient, -55°C to 155°C operating range). This substitute provides an enhanced power rating of 0.5W (1/2W) compared to the primary part's 0.25W specification. The substitute includes AEC-Q200 automotive qualification, which adds reliability assurance for automotive and high-reliability applications. Both parts share identical package dimensions (0.079" L x 0.049" W) and maintain RoHS3 compliance with REACH unaffected status. The substitute is suitable for direct replacement in applications where the primary part is unavailable or where the enhanced power rating and automotive qualification provide additional design margin.

Frequently Asked Questions (FAQ)

Q: Can the KRL1220E-M-R082-F-T5 be used as a direct replacement for the TLM2ADR082FTD?

A: Yes. Both parts share identical resistance (0.082 ohm), tolerance (±1%), composition (metal foil), package (0805), temperature coefficient (±50ppm/°C), and operating temperature range (-55°C to 155°C). The substitute features a higher power rating (0.5W versus 0.25W) and AEC-Q200 automotive certification, which do not prevent direct substitution. The physical dimensions are equivalent, and both maintain RoHS3 compliance.

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

A: The TLM2ADR082FTD is rated for 0.25W (1/4W) power dissipation, while the KRL1220E-M-R082-F-T5 is rated for 0.5W (1/2W). In applications where the circuit dissipates power within the 0.25W specification, either part functions identically. The substitute's higher power rating provides additional thermal margin and allows operation in applications requiring up to 0.5W dissipation. The higher rating does not degrade performance in lower-power applications.

Q: Are there physical compatibility concerns with the substitute part?

A: Both parts use the 0805 (2012 Metric) package with identical length and width dimensions (0.079" L x 0.049" W). The seated height differs slightly: the primary part measures 0.024" (0.60mm) maximum, while the substitute measures 0.028" (0.70mm) maximum. This 0.004" (0.10mm) difference is within standard PCB assembly tolerances and does not affect board-level compatibility or component placement.

Q: What compliance certifications apply to each part?

A: Both the TLM2ADR082FTD and KRL1220E-M-R082-F-T5 are RoHS3 compliant and REACH unaffected. The substitute additionally carries AEC-Q200 automotive qualification, which certifies reliability for automotive applications. This additional certification does not restrict use in non-automotive applications.

Q: Are these parts suitable for current sensing applications?

A: Yes. Both parts are specified for current sense applications. The metal foil composition and ±1% tolerance provide the precision and stability required for accurate current measurement across the operating temperature range of -55°C to 155°C.

Q: What is the moisture sensitivity rating for these components?

A: Both parts carry Moisture Sensitivity Level (MSL) 1, which indicates unlimited moisture sensitivity. These components do not require special moisture control during storage, handling, or assembly.
