RT1206BRE07124KL Equivalent & Substitute Parts

Part Overview

The RT1206BRE07124KL is a 124 kOhms ±0.1% thin film chip resistor in 1206 (3216 Metric) package format, rated for 0.25W (1/4W) power dissipation. Manufactured by YAGEO under the RT series, this component is actively produced and widely used in precision analog circuits requiring tight tolerance specifications. Substitute parts are identified when equivalent electrical performance, mechanical compatibility, and compliance certifications align with the original specification.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RT1206BRE07124KL is determined by the following critical parameters:

• Resistance Value: Must be 124 kOhms
• Tolerance: Must be ±0.1% or tighter
• Power Rating: Must be 0.25W or greater
• Package: Must be 1206 (3216 Metric)
• Composition: Thin film construction
• Operating Temperature: Must support -55°C ~ 155°C range
• Compliance: RoHS3 and REACH requirements

Two substitute parts meet these criteria: RT1206BRD07124KL (YAGEO) and ERA-8AEB1243V (Panasonic Electronic Components). Both maintain identical electrical specifications and package compatibility while differing in temperature coefficient performance and automotive qualification status.

Parameter Comparison

Engineering Selection Recommendations

RT1206BRD07124KL is a direct equivalent from YAGEO with improved temperature coefficient performance (±25ppm/°C versus ±50ppm/°C). Both YAGEO parts maintain identical package dimensions and are suitable for general industrial and commercial applications requiring ROHS3 compliance.

ERA-8AEB1243V from Panasonic Electronic Components provides the same electrical specifications with AEC-Q200 automotive qualification. This part is appropriate for automotive and high-reliability applications. Physical dimensions differ slightly (length 3.20mm versus 3.10mm, height 0.70mm versus 0.65mm), requiring PCB layout verification for space-constrained designs.

All three parts are actively produced and maintain full RoHS3 and REACH compliance.

Frequently Asked Questions (FAQ)

Q: Can RT1206BRD07124KL replace RT1206BRE07124KL in any application?

A: Yes. Both parts share identical resistance, tolerance, power rating, and package specifications. The RT1206BRD07124KL features a lower temperature coefficient (±25ppm/°C), which provides superior stability across the operating temperature range.

Q: Is ERA-8AEB1243V suitable for non-automotive applications?

A: Yes. AEC-Q200 qualification is a superset of standard industrial requirements. The part is fully compatible with commercial and industrial designs. Verify PCB layout clearances due to slightly larger physical dimensions (3.20mm length, 0.70mm height).

Q: What is the primary difference between these three parts?

A: Resistance, tolerance, power rating, and operating temperature are identical. RT1206BRD07124KL offers improved temperature coefficient stability. ERA-8AEB1243V adds automotive-grade qualification and slightly larger physical dimensions.

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

A: Yes. All three parts are supplied in Tape & Reel (TR) format suitable for automated assembly.

Q: Do these parts require different PCB footprints?

A: RT1206BRE07124KL and RT1206BRD07124KL use identical 1206 footprints. ERA-8AEB1243V uses a 1206 footprint with slightly larger physical dimensions; standard 1206 footprints accommodate this part, but verify clearances in space-constrained layouts.
