TLM2ADR022FTD Equivalent & Substitute Parts

Part Overview

The TLM2ADR022FTD is a 22 mOhm ±1% metal foil chip resistor manufactured by TE Connectivity Passive Product, rated for 0.25W (1/4W) power dissipation in a 0805 (2012 Metric) surface-mount package. This component is designed for current sensing applications and operates across the temperature range of -55°C to 155°C. The part is currently active in production with RoHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Equivalent and substitute parts are identified to provide design flexibility, accommodate supply chain variations, or meet specific application requirements such as higher power ratings or automotive qualification standards.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TLM2ADR022FTD is determined by strict equivalence in the following critical parameters:

Mandatory Equivalence Parameters:

• Resistance value: 22 mOhms
• Tolerance: ±1%
• Package / Case: 0805 (2012 Metric)
• Composition: Metal Foil
• Temperature Coefficient: ±50ppm/°C
• Operating Temperature Range: -55°C to 155°C
• Number of Terminations: 2
• Features: Current Sense

Allowable Variation Parameters:

• Power Rating: Substitute parts may have equal or higher power ratings (0.25W or greater)
• Certifications and Ratings: Substitute parts may include additional certifications (such as AEC-Q200 automotive qualification) without affecting base functionality
• Compliance Status: Substitute parts must maintain RoHS3 compliance and MSL 1 rating

The KRL1220E-M-R022-F-T5 from Susumu meets all mandatory equivalence criteria and provides an upgrade path with doubled power rating (0.5W vs. 0.25W) and automotive AEC-Q200 qualification.

Parameter Comparison

Engineering Selection Recommendations

TLM2ADR022FTD Selection Criteria:

• Standard current sensing applications with 0.25W power dissipation requirements
• Applications not requiring automotive qualification
• Cost-optimized designs where base specifications are sufficient
• Active product status ensures continued availability and supply chain stability

KRL1220E-M-R022-F-T5 Selection Criteria:

• Automotive applications requiring AEC-Q200 qualification
• Designs requiring higher power dissipation margin (0.5W rating provides 2x headroom)
• Applications benefiting from enhanced reliability certification
• Designs where thermal performance improvement is advantageous
• Active product status with higher inventory availability (104,913 pcs vs. 1,061 pcs)

Both parts maintain identical electrical performance in current sensing circuits due to equivalent resistance, tolerance, temperature coefficient, and operating temperature range. The substitute part provides additional design margin and automotive-grade reliability without circuit redesign.

Frequently Asked Questions (FAQ)

Q: Can KRL1220E-M-R022-F-T5 be used as a direct replacement for TLM2ADR022FTD?

A: Yes. Both parts share identical resistance (22 mOhms), tolerance (±1%), package (0805), composition (metal foil), temperature coefficient (±50ppm/°C), and operating temperature range (-55°C to 155°C). The substitute part has a higher power rating (0.5W vs. 0.25W) and automotive AEC-Q200 certification, making it functionally compatible in all applications where the original part operates.

Q: What is the physical difference between these parts?

A: The maximum seated height differs slightly: TLM2ADR022FTD is 0.026" (0.65mm) while KRL1220E-M-R022-F-T5 is 0.028" (0.70mm). Both parts use the same 0805 (2012 Metric) package footprint with identical length (0.079") and width (0.049"). This 0.002" height difference is within standard PCB assembly tolerances and does not affect board-level compatibility.

Q: Why does the substitute part have a higher power rating?

A: The KRL1220E-M-R022-F-T5 is rated for 0.5W (1/2W) compared to the 0.25W (1/4W) rating of the TLM2ADR022FTD. This higher power rating reflects the substitute part's thermal design and is an upgrade characteristic. In applications where the original 0.25W part is sufficient, the higher-rated substitute part operates with additional thermal margin without affecting circuit performance.

Q: Are there compliance or certification differences?

A: The KRL1220E-M-R022-F-T5 includes AEC-Q200 automotive qualification, which the TLM2ADR022FTD does not specify. Both parts are RoHS3 compliant and carry MSL 1 (unlimited moisture sensitivity) rating. The substitute part's additional automotive certification does not restrict its use in non-automotive applications.

Q: What is the impact on circuit design when substituting these parts?

A: No circuit redesign is required. Both parts have identical electrical characteristics for current sensing applications: same resistance value, tolerance, temperature coefficient, and operating temperature range. The substitute part's higher power rating and automotive certification represent design improvements without requiring modifications to schematic or layout.

Q: How do these parts differ in packaging and availability?

A: Both parts are supplied in Tape & Reel (TR) packaging. The TLM2ADR022FTD has 1,061 pcs in stock, while the KRL1220E-M-R022-F-T5 has significantly higher availability at 104,913 pcs. Both parts maintain active product status, ensuring continued supply chain support.
