RT1206FRE07340KL Equivalent & Substitute Parts

Part Overview

The RT1206FRE07340KL is a 340 kOhms ±1% thin film chip resistor in 1206 (3216 Metric) package manufactured by YAGEO. This surface mount device is rated for 0.25W (1/4W) power dissipation and operates across -55°C to 155°C. The part is ROHS3 compliant and carries MSL Level 1 (Unlimited) moisture sensitivity rating, making it suitable for general industrial and commercial applications. Substitute parts are identified to provide options for improved tolerance specifications, enhanced reliability certifications, or alternative sourcing when the primary part becomes unavailable.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RT1206FRE07340KL is determined by the following mandatory parameters:

• Resistance Value: Must be 340 kOhms (exact match required)
• Package / Case: Must be 1206 (3216 Metric) for PCB footprint compatibility
• Power Rating: Must be 0.25W (1/4W) or higher
• Composition: Thin film technology maintains performance characteristics
• Operating Temperature Range: Must cover -55°C to 155°C minimum
• RoHS Compliance: ROHS3 Compliant status required

Tolerance, temperature coefficient, and certification levels (such as AEC-Q200) represent upgrade paths rather than substitution barriers. Parts with tighter tolerance specifications (±0.5%, ±0.1%) and lower temperature coefficients (±25ppm/°C) are direct functional upgrades while maintaining all mandatory compatibility parameters.

Parameter Comparison

Engineering Selection Recommendations

RT1206DRD07340KL is a direct upgrade from the main part, offering improved tolerance (±0.5% vs ±1%) and reduced temperature coefficient (±25ppm/°C vs ±50ppm/°C) while maintaining identical package, power rating, and operating temperature specifications. Both parts are manufactured by YAGEO and carry ROHS3 compliance. This substitute is suitable for applications requiring tighter resistance accuracy without design modifications.

ERA-8AEB3403V provides the highest tolerance specification (±0.1%) and equivalent temperature coefficient (±25ppm/°C). This Panasonic part carries AEC-Q200 automotive qualification, making it appropriate for automotive and high-reliability applications. Physical dimensions differ slightly (3.20mm L vs 3.10mm L; 0.70mm H vs 0.65mm H), requiring verification of PCB layout clearances despite identical 1206 package designation. ROHS3 compliance and MSL Level 1 rating are maintained.

Frequently Asked Questions (FAQ)

Q: Can RT1206DRD07340KL replace RT1206FRE07340KL without PCB modifications?

A: Yes. Both parts share identical 1206 (3216 Metric) package dimensions, footprint, power rating, and operating temperature range. The substitute offers improved tolerance and temperature coefficient specifications.

Q: Is ERA-8AEB3403V a direct drop-in replacement?

A: Physical compatibility requires verification. While both use 1206 package designation, ERA-8AEB3403V has slightly larger dimensions (3.20mm L × 0.70mm H vs 3.10mm L × 0.65mm H). Confirm PCB layout clearances before substitution. Electrical compatibility is maintained.

Q: What is the primary advantage of ERA-8AEB3403V?

A: AEC-Q200 automotive qualification and ±0.1% tolerance specification. This part is suitable for automotive, aerospace, and high-reliability applications where tighter tolerance and enhanced qualification are required.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. RT1206FRE07340KL, RT1206DRD07340KL, and ERA-8AEB3403V are all ROHS3 compliant with MSL Level 1 (Unlimited) moisture sensitivity rating.

Q: Can I use a substitute with lower tolerance in a circuit designed for ±1%?

A: Yes. Parts with tighter tolerance (±0.5%, ±0.1%) are functionally superior and will perform within the original design specifications. No circuit modifications are required.

Q: What is the difference between temperature coefficient values?

A: Temperature coefficient indicates resistance change per degree Celsius. RT1206FRE07340KL has ±50ppm/°C; substitutes have ±25ppm/°C. Lower values indicate better stability across temperature extremes, beneficial for precision applications.
