RT1206CRE07124KL Equivalent & Substitute Parts

Part Overview

The RT1206CRE07124KL is a 124 kOhms ±0.25% thin film chip resistor in 1206 (3216 Metric) package manufactured by YAGEO. This surface mount device is rated for 0.25W power dissipation and operates across -55°C to 155°C. The part is Active status and ROHS3 compliant, making it suitable for general industrial and commercial applications requiring precision resistive elements.

Substitute parts are identified when they maintain identical resistance value, package form factor, power rating, and operating temperature range while offering improved electrical characteristics or enhanced qualification status.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RT1206CRE07124KL is determined by strict equivalence in the following parameters:

• Resistance value: 124 kOhms (exact match required)
• Package form factor: 1206 (3216 Metric)
• Power rating: 0.25W minimum
• Operating temperature range: -55°C to 155°C minimum
• Composition: Thin film construction
• Termination count: 2 terminations

Substitute parts identified in this reference maintain all mandatory parameters. Tolerance and temperature coefficient may be improved (tighter specification) without affecting substitutability. Automotive qualification (AEC-Q200) represents an enhancement in reliability screening and does not restrict use in non-automotive applications.

Parameter Comparison

Engineering Selection Recommendations

RT1206BRD07124KL (YAGEO) serves as a direct upgrade path, offering improved tolerance specification (±0.1% versus ±0.25%) and reduced temperature coefficient (±25ppm/°C versus ±50ppm/°C) while maintaining identical package, power rating, and operating temperature range. Both YAGEO parts are Active status with ROHS3 compliance.

ERA-8AEB1243V (Panasonic Electronic Components) provides equivalent electrical performance with additional AEC-Q200 automotive qualification. Physical dimensions show minor variation (0.126" L x 0.063" W versus 0.122" L x 0.063" W; height 0.028" versus 0.026"), which must be verified against PCB layout constraints. This part is suitable for applications requiring automotive-grade reliability screening.

Selection between substitute parts depends on design requirements: tolerance precision, temperature stability, and automotive qualification status. All three parts maintain functional equivalence for the 124 kOhms 1206 thin film resistor application.

Frequently Asked Questions (FAQ)

Q: Can RT1206BRD07124KL replace RT1206CRE07124KL in existing designs?

A: Yes. Both parts share identical resistance, package, power rating, and operating temperature range. RT1206BRD07124KL offers improved tolerance and temperature coefficient specifications, making it a direct substitute without circuit redesign.

Q: Is ERA-8AEB1243V compatible with the original RT1206CRE07124KL footprint?

A: Physical dimensions differ slightly. ERA-8AEB1243V measures 0.126" L x 0.063" W with 0.028" seated height, compared to RT1206CRE07124KL at 0.122" L x 0.063" W with 0.026" seated height. PCB layout verification is required to confirm footprint compatibility, though both use standard 1206 package designation.

Q: What does AEC-Q200 qualification mean for ERA-8AEB1243V?

A: AEC-Q200 indicates the part has undergone automotive-grade reliability testing and screening. This qualification does not restrict use in non-automotive applications; it represents enhanced quality assurance suitable for demanding environments.

Q: Are all three parts ROHS3 compliant?

A: Yes. RT1206CRE07124KL, RT1206BRD07124KL, and ERA-8AEB1243V are all ROHS3 compliant with Moisture Sensitivity Level 1 (Unlimited), meeting environmental and regulatory requirements for commercial and industrial applications.

Q: Which substitute offers the best temperature stability?

A: Both RT1206BRD07124KL and ERA-8AEB1243V feature ±25ppm/°C temperature coefficient, compared to ±50ppm/°C for the original RT1206CRE07124KL. Selection between these two depends on tolerance requirements and automotive qualification necessity.
