RT1206FRE0734KL Equivalent & Substitute Parts

Part Overview

The RT1206FRE0734KL is a 34 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 maintains Active product status with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Substitute parts are identified when equivalent resistance values, package dimensions, power ratings, and operating temperature ranges align with application requirements while offering improved tolerance or automotive-grade certifications.

Substitute Part Grouping Explanation

Substitution eligibility for the RT1206FRE0734KL is determined by the following mandatory parameters:

• Resistance Value: Must be 34 kOhms
• Package Type: Must be 1206 (3216 Metric)
• Power Rating: Must be 0.25W (1/4W) minimum
• Composition: Thin film construction
• Operating Temperature Range: Must cover -55°C ~ 155°C
• RoHS Compliance: ROHS3 Compliant

Substitute parts identified below meet all mandatory parameters. Tolerance and temperature coefficient may vary as performance enhancements without affecting functional compatibility in standard applications.

Parameter Comparison

Engineering Selection Recommendations

RT1206BRD0734KL (YAGEO): This substitute offers improved tolerance (±0.1% versus ±1%) and reduced temperature coefficient (±25ppm/°C versus ±50ppm/°C) while maintaining identical package, power rating, and operating temperature range. Selection is appropriate for applications requiring tighter resistance accuracy without automotive qualification requirements.

ERA-8AEB3402V (Panasonic Electronic Components): This substitute provides equivalent tolerance and temperature coefficient improvements as RT1206BRD0734KL with additional AEC-Q200 automotive qualification. Selection is appropriate for automotive applications, harsh environment deployments, or systems requiring automotive-grade component reliability. Physical dimensions vary slightly (0.126" L x 0.063" W versus 0.122" L x 0.063" W; height 0.028" versus 0.026"), requiring PCB layout verification.

Frequently Asked Questions (FAQ)

Q: Can RT1206BRD0734KL replace RT1206FRE0734KL in any application?

A: Yes, within the constraints of PCB layout and tolerance requirements. RT1206BRD0734KL maintains identical package dimensions, power rating, and operating temperature range. The improved tolerance (±0.1% versus ±1%) and lower temperature coefficient (±25ppm/°C versus ±50ppm/°C) make it suitable for applications where the original part's ±1% tolerance is acceptable or where tighter tolerance is beneficial.

Q: What are the physical differences between ERA-8AEB3402V and RT1206FRE0734KL?

A: Both use 1206 (3216 Metric) packages. ERA-8AEB3402V dimensions are 0.126" L x 0.063" W with 0.028" maximum seated height, compared to RT1206FRE0734KL at 0.122" L x 0.063" W with 0.026" maximum seated height. The length and height differences require PCB footprint verification before substitution.

Q: Is ERA-8AEB3402V suitable for automotive applications?

A: Yes. ERA-8AEB3402V carries AEC-Q200 automotive qualification, making it suitable for automotive and harsh environment applications. RT1206FRE0734KL and RT1206BRD0734KL do not carry automotive ratings.

Q: What determines whether a part can substitute for RT1206FRE0734KL?

A: Mandatory parameters are 34 kOhms resistance, 1206 package, 0.25W power rating, thin film composition, -55°C to 155°C operating range, and ROHS3 compliance. Tolerance, temperature coefficient, and automotive certification are secondary parameters that may vary.

Q: Can I use a substitute part with different tolerance in a precision circuit?

A: Tolerance selection depends on circuit requirements. RT1206BRD0734KL and ERA-8AEB3402V offer ±0.1% tolerance versus the original ±1%, providing improved accuracy. Circuit design specifications determine whether tighter tolerance is necessary or whether the original tolerance is sufficient.
