RT1206FRE07243RL Equivalent & Substitute Parts

Part Overview

The RT1206FRE07243RL is a 243 Ohm thin film chip resistor manufactured by YAGEO in the 1206 (3216 Metric) package format. This component is rated for 0.25W power dissipation with ±1% tolerance and operates across the temperature range of -55°C to 155°C. The part maintains Active product status and is ROHS3 compliant with unlimited moisture sensitivity rating (MSL 1).

Substitute parts are identified when electrical specifications (resistance value, power rating, package type) and mechanical dimensions remain compatible, while allowing for improvements in tolerance, temperature coefficient, or enhanced certifications such as automotive qualification.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RT1206FRE07243RL is determined by the following mandatory parameters:

• Resistance value: 243 Ohms (exact match required)
• Power rating: 0.25W minimum
• Package type: 1206 (3216 Metric) form factor
• Composition: Thin Film technology
• Operating temperature range: -55°C to 155°C minimum coverage
• RoHS compliance: ROHS3 Compliant
• Moisture sensitivity: MSL 1 or better

Identified substitutes maintain all mandatory parameters while offering enhanced specifications in tolerance (±0.1% versus ±1%) and temperature coefficient (±25ppm/°C versus ±50ppm/°C). One substitute includes automotive AEC-Q200 qualification for applications requiring enhanced reliability standards.

Parameter Comparison

Engineering Selection Recommendations

All three parts maintain Active product status and ROHS3 compliance. Selection between RT1206FRE07243RL and its substitutes depends on application-specific requirements:

RT1206BRD07243RL offers improved tolerance (±0.1%) and reduced temperature coefficient (±25ppm/°C) compared to the primary part, maintaining identical package dimensions and thermal operating range. This substitute is suitable for general industrial applications requiring tighter resistance accuracy.

ERA-8AEB2430V provides the same tolerance and temperature coefficient improvements as RT1206BRD07243RL while adding AEC-Q200 automotive qualification. This part is specified for automotive and high-reliability applications. Dimensional variation exists: ERA-8AEB2430V measures 0.126" L × 0.063" W (3.20mm × 1.60mm) with 0.028" maximum seated height, compared to 0.122" L × 0.063" W (3.10mm × 1.60mm) with 0.026" maximum seated height for the primary part. This dimensional difference requires PCB layout verification before substitution.

Frequently Asked Questions (FAQ)

Q: Can RT1206BRD07243RL be used as a direct replacement for RT1206FRE07243RL?

A: Yes. Both parts share identical resistance value (243 Ohms), power rating (0.25W), package type (1206), composition (thin film), operating temperature range (-55°C to 155°C), and RoHS compliance. RT1206BRD07243RL provides enhanced tolerance (±0.1% versus ±1%) and lower temperature coefficient (±25ppm/°C versus ±50ppm/°C). No PCB modifications are required.

Q: Is ERA-8AEB2430V a direct replacement?

A: ERA-8AEB2430V is electrically compatible but requires PCB layout verification due to dimensional differences. The part is 0.004" longer (3.20mm versus 3.10mm) and 0.002" taller (0.70mm versus 0.65mm maximum seated height). Confirm pad spacing and component clearance before substitution. The part is suitable for applications requiring AEC-Q200 automotive qualification.

Q: What determines substitution eligibility for 243 Ohm 1206 thin film resistors?

A: Mandatory parameters are resistance value (243 Ohms exact), power rating (0.25W minimum), package type (1206 form factor), composition (thin film), operating temperature coverage (-55°C to 155°C minimum), RoHS compliance (ROHS3), and moisture sensitivity (MSL 1 or better). Tolerance and temperature coefficient may vary without affecting substitution eligibility.

Q: Which substitute should be selected for automotive applications?

A: ERA-8AEB2430V is qualified to AEC-Q200 automotive standards and is the appropriate selection for automotive applications. Verify PCB layout compatibility due to dimensional variations before implementation.

Q: Are all three parts available in Tape & Reel packaging?

A: Yes. RT1206FRE07243RL, RT1206BRD07243RL, and ERA-8AEB2430V are all supplied in Tape & Reel (TR) packaging format suitable for automated assembly processes.
