RT1206DRE07124KL Equivalent & Substitute Parts

Part Overview

The RT1206DRE07124KL is a 124 kOhms ±0.5% 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 component is ROHS3 compliant with MSL 1 rating, indicating unlimited moisture sensitivity protection. Substitute parts are identified when equivalent resistance values, package dimensions, power ratings, and operating temperature ranges are maintained while potentially offering improved tolerance or automotive-grade certifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RT1206DRE07124KL is determined by the following mandatory parameters:

• Resistance value: 124 kOhms (exact match required)
• Package / Case: 1206 (3216 Metric) (exact match required)
• Power rating: 0.25W minimum
• Operating temperature range: -55°C to 155°C minimum
• Composition: Thin Film
• RoHS compliance: ROHS3 or equivalent

Tolerance and temperature coefficient may vary within acceptable engineering margins. Substitute parts identified include RT1206BRD07124KL (YAGEO, tighter tolerance) and ERA-8AEB1243V (Panasonic, automotive-grade certification).

Parameter Comparison

Engineering Selection Recommendations

RT1206BRD07124KL serves as a direct upgrade path within the YAGEO RT series, offering improved tolerance (±0.1% versus ±0.5%) and reduced temperature coefficient (±25ppm/°C versus ±50ppm/°C) while maintaining identical package, power rating, and operating temperature specifications. Both components are ROHS3 compliant with MSL 1 rating.

ERA-8AEB1243V provides an alternative from Panasonic with equivalent electrical specifications and AEC-Q200 automotive qualification. Physical dimensions differ slightly (0.126" L x 0.063" W versus 0.122" L x 0.063" W; height 0.028" versus 0.026"), requiring verification of PCB layout constraints. This option is suitable for applications requiring automotive-grade component certification.

Frequently Asked Questions (FAQ)

Q: Can RT1206BRD07124KL replace RT1206DRE07124KL in all applications?

A: Yes. Both components share identical resistance, package, power rating, and operating temperature range. RT1206BRD07124KL offers tighter tolerance and lower temperature coefficient, making it suitable for precision applications without design modification.

Q: Is ERA-8AEB1243V compatible with existing PCB layouts designed for RT1206DRE07124KL?

A: Physical dimensions differ slightly. ERA-8AEB1243V measures 0.126" L x 0.063" W with 0.028" maximum seated height, compared to 0.122" L x 0.063" W with 0.026" maximum seated height for RT1206DRE07124KL. PCB footprint and clearance verification is required before substitution.

Q: What is the primary advantage of selecting ERA-8AEB1243V?

A: ERA-8AEB1243V carries AEC-Q200 automotive qualification, making it suitable for automotive and high-reliability applications. It maintains equivalent electrical performance with ±0.1% tolerance and ±25ppm/°C temperature coefficient.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. RT1206DRE07124KL, RT1206BRD07124KL, and ERA-8AEB1243V are all ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating.

Q: What tolerance should be specified for circuit design?

A: The main part RT1206DRE07124KL is rated ±0.5%. Both substitute parts offer ±0.1% tolerance. Circuit design should account for the tolerance of the selected component to ensure performance margins.
