TLM2ADR027FTD Equivalent & Substitute Parts

Part Overview

The TLM2ADR027FTD is a 27 milliohm, ±1% tolerance, 0.25W metal foil chip resistor manufactured by TE Connectivity in the 0805 (2012 Metric) package. This component is designed for current sensing applications and operates across the temperature range of -55°C to 155°C. The part maintains Active product status and is RoHS3 compliant with unlimited moisture sensitivity rating (MSL 1). Substitute parts are identified when equivalent electrical and mechanical specifications are required for design flexibility, supply chain continuity, or application-specific performance enhancements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TLM2ADR027FTD is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 27 mOhms
• Tolerance: ±1%
• Package / Case: 0805 (2012 Metric)
• Composition: Metal Foil
• Temperature Coefficient: ±50ppm/°C
• Operating Temperature Range: -55°C to 155°C
• Features: Current Sense capability
• Number of Terminations: 2
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Allowable Variation:

• Power rating may increase from 0.25W to higher ratings (0.5W or greater) without compromising substitution validity, as higher power ratings provide equal or superior thermal performance in the same package footprint.

The substitute part KRL1220E-M-R027-F-T5 meets all mandatory parameters and includes an upgraded power rating of 0.5W with automotive AEC-Q200 qualification.

Parameter Comparison

Engineering Selection Recommendations

TLM2ADR027FTD (TE Connectivity) is suitable for applications where the 0.25W power rating is sufficient and standard industrial compliance is required. The part maintains Active product status with full RoHS3 compliance and unlimited moisture sensitivity rating.

KRL1220E-M-R027-F-T5 (Susumu) provides an upgraded alternative with doubled power rating (0.5W) while maintaining identical electrical specifications and package dimensions. This substitute includes automotive AEC-Q200 qualification, making it applicable to automotive and high-reliability applications. The marginal increase in seated height (0.028" versus 0.026") remains within standard PCB assembly tolerances for 0805 packages.

Both parts are Active products with equivalent compliance certifications (ROHS3, REACH Unaffected, EAR99). Selection between these parts depends on application power dissipation requirements and automotive qualification necessity.

Frequently Asked Questions (FAQ)

Q: Can KRL1220E-M-R027-F-T5 be used as a direct replacement for TLM2ADR027FTD?

A: Yes. Both parts share identical resistance (27 mOhms), tolerance (±1%), package (0805), composition (metal foil), 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), which does not restrict substitution in applications designed for the original 0.25W specification.

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

A: Both parts measure 0.079" L x 0.049" W (2.00mm x 1.25mm). The seated height differs slightly: TLM2ADR027FTD is 0.026" (0.65mm) maximum, while KRL1220E-M-R027-F-T5 is 0.028" (0.70mm) maximum. This 0.002" (0.05mm) difference is within standard PCB assembly clearance specifications for 0805 packages.

Q: Are both parts suitable for current sensing applications?

A: Yes. Both parts are specified with current sense features and metal foil composition, which provides the low resistance and precision tolerance required for current sensing circuits.

Q: What compliance certifications apply to both parts?

A: Both parts are RoHS3 compliant, REACH unaffected, and classified under ECCN EAR99. Both carry HTSUS code 8533.21.0030. The substitute part includes additional automotive AEC-Q200 qualification.

Q: Is there a difference in moisture sensitivity between these parts?

A: No. Both parts carry Moisture Sensitivity Level 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.

Q: What is the temperature coefficient specification for both parts?

A: Both parts specify ±50ppm/°C temperature coefficient across the operating range of -55°C to 155°C, ensuring stable resistance performance across industrial and automotive temperature extremes.
