RT1206FRE072K05L Equivalent & Substitute Parts

Part Overview

The RT1206FRE072K05L is a 2.05 kOhms ±1% thin film chip resistor in 1206 (3216 Metric) package format, rated for 0.25W power dissipation. This YAGEO component operates across -55°C to 155°C and maintains ROHS3 compliance with unlimited moisture sensitivity rating. The part is currently active in production with 1138 units in stock.

Substitute parts are identified when equivalent resistance values, package dimensions, power ratings, and operating temperature ranges align with the original specification, while offering improved tolerance, temperature coefficient performance, or enhanced reliability certifications.

Substitute Part Grouping Explanation

Substitution eligibility for the RT1206FRE072K05L is determined by the following mandatory parameters:

• Resistance value: 2.05 kOhms (exact match required)
• Package format: 1206 (3216 Metric) with compatible footprint dimensions
• Power rating: Minimum 0.25W
• Composition: Thin film construction
• Operating temperature range: Minimum -55°C ~ 155°C coverage
• RoHS compliance: ROHS3 or equivalent

Substitute parts may offer improved tolerance (lower percentage deviation), enhanced temperature coefficient stability, or additional reliability certifications while maintaining full compatibility with the original design requirements.

Parameter Comparison

Engineering Selection Recommendations

RT1206DRE072K05L (YAGEO): This substitute offers improved tolerance specification (±0.5% versus ±1%) while maintaining identical power rating, package format, and operating temperature range. Both components share the same manufacturer and series lineage, ensuring design compatibility. Selection is appropriate for applications requiring tighter resistance accuracy without additional certification requirements.

ERA-8AEB2051V (Panasonic Electronic Components): This substitute provides the highest tolerance specification (±0.1%) and superior temperature coefficient performance (±25ppm/°C versus ±50ppm/°C). The component carries AEC-Q200 automotive qualification, indicating enhanced reliability validation. Physical dimensions show minor variation (0.126" L × 0.063" W versus 0.122" L × 0.063" W), with maximum seated height of 0.028" versus 0.026". Selection is appropriate for precision applications or designs requiring automotive-grade component reliability.

Frequently Asked Questions (FAQ)

Q: Can RT1206DRE072K05L directly replace RT1206FRE072K05L in existing designs?

A: Yes. Both components share identical resistance value (2.05 kOhms), power rating (0.25W), package format (1206), operating temperature range (-55°C ~ 155°C), and RoHS compliance. The substitute offers improved tolerance (±0.5% versus ±1%), making it a direct upgrade with no design modifications required.

Q: What are the physical compatibility considerations for ERA-8AEB2051V?

A: The ERA-8AEB2051V maintains the same 1206 package footprint and is mechanically compatible. Dimensional variations are minimal: length increases from 3.10mm to 3.20mm, and maximum seated height increases from 0.65mm to 0.70mm. These differences remain within standard PCB layout tolerances for 1206 components.

Q: When should ERA-8AEB2051V be selected over YAGEO alternatives?

A: Selection of the ERA-8AEB2051V is appropriate when designs require AEC-Q200 automotive qualification, superior tolerance specification (±0.1%), or enhanced temperature stability (±25ppm/°C). Applications in automotive, industrial, or precision measurement environments benefit from these enhanced specifications.

Q: Are all substitute parts available in equivalent packaging formats?

A: All three components are supplied in Tape & Reel (TR) packaging, maintaining supply chain compatibility and automated assembly compatibility.

Q: Do tolerance differences affect circuit performance?

A: Tolerance differences impact circuit accuracy. The RT1206FRE072K05L (±1%) allows ±20.5 Ohms deviation. The RT1206DRE072K05L (±0.5%) limits deviation to ±10.25 Ohms. The ERA-8AEB2051V (±0.1%) restricts deviation to ±2.05 Ohms. Selection depends on circuit sensitivity to resistance variation.
