TLM2BDR056FTD Equivalent & Substitute Parts

Part Overview

The TLM2BDR056FTD is a 56 milliohm, ±1% tolerance, 0.5W metal foil chip resistor manufactured by TE Connectivity Passive Product in the 1206 (3216 Metric) package. This component is designed for current sensing applications and is classified as Active product status. The part is supplied in Tape & Reel packaging with unlimited moisture sensitivity level (MSL 1). Substitute parts are identified when equivalent electrical and mechanical specifications are required, or when alternative sourcing, compliance certifications, or enhanced power ratings are necessary for system requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TLM2BDR056FTD is permissible when the following core electrical and mechanical parameters remain constant or are enhanced:

Mandatory Matching Parameters:

• Resistance value: 56 mOhms
• Tolerance: ±1%
• Package / Case: 1206 (3216 Metric)
• Composition: Metal Foil
• Temperature Coefficient: ±50ppm/°C
• Operating Temperature Range: -55°C to 155°C
• Application: Current Sense

Allowable Variations:

• Power rating may be equal or higher (upgrade from 0.5W to 0.75W is acceptable)
• RoHS compliance status may differ (upgrade from non-compliant to compliant is acceptable)
• Manufacturer and series designation may differ
• Physical dimensions may vary within 1206 package tolerance

The identified substitute part KRL1632E-M-R056-F-T5 meets all mandatory matching parameters and provides an enhanced power rating of 0.75W with improved RoHS3 compliance and automotive AEC-Q200 qualification.

Parameter Comparison

Engineering Selection Recommendations

TLM2BDR056FTD Selection Criteria:

• Applications requiring TE Connectivity sourcing or existing supply chain integration
• Systems with no RoHS compliance requirement
• Designs where 0.5W power dissipation is sufficient
• Non-automotive applications

KRL1632E-M-R056-F-T5 Selection Criteria:

• Applications requiring RoHS3 compliance
• Automotive systems requiring AEC-Q200 qualification
• Designs benefiting from higher 0.75W power rating for thermal margin
• Systems with REACH compliance requirements
• Applications where Susumu component sourcing is preferred

Both parts are Active product status and suitable for production use. The substitute part provides enhanced compliance certifications and automotive qualification without compromising electrical or mechanical compatibility. Selection between these parts is determined by regulatory requirements, supply chain preferences, and thermal design margins rather than functional limitations.

Frequently Asked Questions (FAQ)

Q: Can KRL1632E-M-R056-F-T5 directly replace TLM2BDR056FTD in existing designs?

A: Yes. Both parts share identical resistance (56 mOhms), tolerance (±1%), temperature coefficient (±50ppm/°C), operating temperature range (-55°C to 155°C), package (1206), and composition (metal foil). The substitute has a higher power rating (0.75W vs. 0.5W), which is compatible with designs rated for 0.5W operation. Physical dimensions are within 1206 package tolerance.

Q: What is the primary difference between these two parts?

A: The KRL1632E-M-R056-F-T5 provides enhanced power rating (0.75W), RoHS3 compliance, and automotive AEC-Q200 qualification. The TLM2BDR056FTD is RoHS non-compliant and rated for 0.5W. Electrical performance is identical.

Q: Are there any PCB layout or footprint considerations when substituting?

A: Both parts use the 1206 (3216 Metric) package. Slight dimensional variations exist (TLM2BDR056FTD: 3.05mm x 1.55mm; KRL1632E-M-R056-F-T5: 3.20mm x 1.60mm), but both conform to 1206 package specifications. Standard 1206 footprints accommodate both parts without modification.

Q: Which part should be selected for automotive applications?

A: KRL1632E-M-R056-F-T5 is qualified to AEC-Q200 automotive standards and is the appropriate selection for automotive systems. TLM2BDR056FTD lacks automotive qualification.

Q: Is the higher power rating of the substitute part a disadvantage?

A: No. A higher power rating (0.75W vs. 0.5W) provides additional thermal margin and does not negatively impact circuit performance. The part operates within the same temperature range and maintains identical electrical characteristics.

Q: What is the significance of RoHS3 compliance on the substitute part?

A: RoHS3 compliance indicates the substitute part meets Restriction of Hazardous Substances regulations. This is required for many commercial and industrial applications, particularly in regulated markets. The main part is RoHS non-compliant.

Q: Can both parts be used interchangeably in the same production batch?

A: From an electrical and mechanical standpoint, yes. However, supply chain and compliance documentation practices should be consistent. If RoHS compliance is required for the end product, only KRL1632E-M-R056-F-T5 should be used.
