RT1206FRE07140RL Equivalent & Substitute Parts

Part Overview

The RT1206FRE07140RL is a 140 Ohms ±1% thin film chip resistor in 1206 (3216 Metric) package rated for 0.25W (1/4W) power dissipation. Manufactured by YAGEO under the RT series, this component is actively produced and ROHS3 compliant. Substitute parts are identified when equivalent electrical specifications and mechanical compatibility are maintained across the same package footprint and resistance value, allowing for direct board-level replacement in applications where tolerance, temperature coefficient, or supplier availability requirements differ.

Substitute Part Grouping Explanation

Substitution eligibility for the RT1206FRE07140RL is determined by the following criteria:

Mandatory Matching Parameters:

• Resistance value: 140 Ohms
• Package / Case: 1206 (3216 Metric)
• Power rating: 0.25W (1/4W) minimum
• Composition: Thin Film
• Operating temperature range: -55°C ~ 155°C minimum
• Moisture Sensitivity Level: 1 (Unlimited)
• RoHS compliance: ROHS3 Compliant

Allowable Variations:

• Tolerance: May be equal or tighter (±1% or better)
• Temperature coefficient: May be equal or lower (±50ppm/°C or better)
• Manufacturer: Different manufacturers permitted if all mandatory parameters match
• Certifications: Additional certifications (e.g., AEC-Q200) do not disqualify substitution

Two substitute parts meet these criteria and are listed below.

Parameter Comparison

Engineering Selection Recommendations

RT1206BRD07140RL (YAGEO): This substitute offers tighter tolerance (±0.1% vs. ±1%) and improved temperature coefficient (±25ppm/°C vs. ±50ppm/°C) while maintaining identical package dimensions and electrical ratings. Both parts are YAGEO RT series thin film resistors with active product status and ROHS3 compliance. Selection is appropriate when higher precision is required without changing supplier or introducing automotive-grade specifications.

ERA-8AEB1400V (Panasonic Electronic Components): This substitute provides equivalent tolerance (±0.1%) and temperature coefficient (±25ppm/°C) with AEC-Q200 automotive qualification. Physical dimensions differ slightly (0.126" L vs. 0.122" L; 0.028" H vs. 0.026" H), remaining within 1206 package classification. Selection is appropriate for automotive applications or when Panasonic supply chain is preferred, provided PCB layout accommodates the minor dimensional variance.

Frequently Asked Questions (FAQ)

Q: Can RT1206BRD07140RL be used as a direct replacement for RT1206FRE07140RL?

A: Yes. Both parts are YAGEO RT series thin film resistors with identical 140 Ohms resistance, 0.25W power rating, 1206 package, and operating temperature range. RT1206BRD07140RL offers tighter tolerance and lower temperature coefficient. Footprint compatibility is confirmed by matching length (0.122"), width (0.063"), and height (0.026").

Q: Is ERA-8AEB1400V compatible with the same PCB footprint?

A: ERA-8AEB1400V is mechanically compatible with 1206 package footprints. Physical dimensions are 0.126" L x 0.063" W (3.20mm x 1.60mm) with 0.028" maximum seated height, compared to 0.122" L x 0.063" W (3.10mm x 1.60mm) with 0.026" height for the original part. The length difference of 0.004" (0.10mm) and height difference of 0.002" (0.05mm) are within standard 1206 package tolerances and do not prevent board-level substitution.

Q: What is the difference between ±1% and ±0.1% tolerance?

A: Tolerance specifies the maximum deviation from the nominal 140 Ohm value. ±1% tolerance allows deviation up to ±1.4 Ohms (139.86 to 140.14 Ohms). ±0.1% tolerance restricts deviation to ±0.14 Ohms (139.986 to 140.014 Ohms). Tighter tolerance is beneficial in precision analog circuits, measurement equipment, and applications sensitive to component value drift.

Q: What does AEC-Q200 certification mean?

A: AEC-Q200 is an automotive qualification standard for passive components. ERA-8AEB1400V meets this specification, making it suitable for automotive applications requiring supplier-certified reliability and quality assurance. Non-automotive applications do not require this certification.

Q: Can I use these substitutes interchangeably in production?

A: Yes, provided your application requirements are met. RT1206BRD07140RL is a direct upgrade within the same manufacturer. ERA-8AEB1400V requires verification that the minor dimensional differences (0.004" length, 0.002" height) do not conflict with PCB layout constraints or assembly equipment specifications. All three parts maintain ROHS3 compliance and MSL 1 rating.
