Key Parameters

Substitute Part Grouping Explanation

The PT1206FR-070R499L from YAGEO qualifies as a substitute based on the following alignment of critical parameters:

• Identical resistance value: 499 mOhms
• Identical tolerance: ±1%
• Identical package: 1206 (3216 Metric)
• Identical composition: Thick Film
• Identical features: Current Sense, Moisture Resistant
• Identical RoHS3 compliance
• Identical MSL rating: 1 (Unlimited)

The substitute part maintains all functional and mechanical compatibility requirements for direct replacement in current sense applications.

Parameter Comparison

Engineering Selection Recommendations

The PT1206FR-070R499L is a direct functional substitute for the obsolete LVC06FR499EV. Both components share identical electrical specifications (499 mOhms ±1%), mechanical package (1206), and composition (thick film). The substitute part is currently in active production with significantly higher inventory availability (96,617 pcs vs. 901 pcs).

The PT1206FR-070R499L includes AEC-Q200 automotive qualification, which provides additional reliability assurance beyond the original part's specification. The substitute's extended operating temperature range (-55°C ~ 155°C vs. -40°C ~ 125°C) and improved temperature coefficient (±75ppm/°C vs. ±100ppm/°C) represent performance enhancements.

The only parameter difference is power rating: the substitute is rated at 0.25W versus the original 0.5W. This difference must be evaluated against actual circuit requirements. If the application requires the full 0.5W dissipation capability, the lower power rating of the substitute may present a limitation.

Frequently Asked Questions (FAQ)

Q: Can PT1206FR-070R499L directly replace LVC06FR499EV in all applications?

A: Direct replacement is possible for applications where power dissipation does not exceed 0.25W. The substitute maintains identical resistance, tolerance, package, and composition. If the circuit design requires 0.5W dissipation capability, alternative components with higher power ratings must be evaluated.

Q: What are the key compatibility factors between these parts?

A: Compatibility is determined by resistance value (499 mOhms), tolerance (±1%), package format (1206), and composition (thick film). Both parts meet these criteria. The substitute additionally qualifies for automotive applications through AEC-Q200 certification.

Q: Why does the substitute have a lower power rating?

A: Power rating differences reflect design and manufacturing variations between manufacturers. The PT1206FR-070R499L is specified at 0.25W, which is a standard rating for this resistance value and package size in YAGEO's product line.

Q: Are there any environmental or compliance differences?

A: Both parts are ROHS3 compliant with MSL rating 1 (unlimited moisture sensitivity level). The substitute includes REACH Unaffected status. Operating temperature ranges differ, with the substitute supporting a wider range (-55°C ~ 155°C vs. -40°C ~ 125°C).

Q: What is the packaging format of the substitute?

A: The PT1206FR-070R499L is supplied in Tape & Reel (TR) format, standard for high-volume procurement. The original part packaging format was not specified in available data.
