RT1206FRE074K3L Equivalent & Substitute Parts

Part Overview

The RT1206FRE074K3L is a 4.3 kOhms ±1% thin film chip resistor manufactured by YAGEO in the 1206 (3216 Metric) package format. This component is rated for 0.25W (1/4W) power dissipation with an operating temperature range of -55°C to 155°C. The part is currently in active production status with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Equivalent and substitute parts are identified when they maintain the same resistance value, package format, power rating, and operating temperature specifications while potentially offering improved tolerance or automotive-grade certifications.

Substitute Part Grouping Explanation

Substitute parts for the RT1206FRE074K3L are qualified based on the following criteria:

Core Compatibility Parameters:

• Resistance value: 4.3 kOhms (exact match required)
• Package format: 1206 (3216 Metric) (exact match required)
• Power rating: 0.25W minimum (1/4W or higher acceptable)
• Operating temperature range: -55°C to 155°C minimum (equal or wider range acceptable)
• Composition: Thin film construction
• Termination count: 2 terminations

Allowable Variations:

• Tolerance: ±1% or tighter (±0.1% acceptable as upgrade)
• Temperature coefficient: Lower values acceptable (±50ppm/°C or better)
• Certifications: Additional automotive or industrial ratings acceptable
• Physical dimensions: Minor variations within package class acceptable

The ERA-8AEB432V qualifies as a direct substitute based on matching all core parameters while offering improved tolerance specification and automotive AEC-Q200 certification.

Parameter Comparison

Engineering Selection Recommendations

The ERA-8AEB432V (Panasonic) is a qualified substitute for the RT1206FRE074K3L. Both components are active production parts with ROHS3 compliance and identical moisture sensitivity ratings. The Panasonic part offers improved tolerance specification (±0.1% versus ±1%) and lower temperature coefficient (±25ppm/°C versus ±50ppm/°C), making it suitable for applications requiring tighter resistance accuracy. The ERA-8AEB432V includes AEC-Q200 automotive qualification, which is beneficial for automotive and industrial applications where component reliability standards are elevated. Physical dimensions remain compatible within the 1206 package class. Selection between these parts should be based on application-specific tolerance requirements and whether automotive-grade certification is necessary for the end application.

Frequently Asked Questions (FAQ)

Q: Can the ERA-8AEB432V replace the RT1206FRE074K3L in existing designs?

A: Yes. Both parts share identical resistance value (4.3 kOhms), package format (1206), power rating (0.25W), and operating temperature range (-55°C to 155°C). The Panasonic part is a direct mechanical and electrical substitute.

Q: What is the difference in tolerance between these parts?

A: The RT1206FRE074K3L has ±1% tolerance, while the ERA-8AEB432V has ±0.1% tolerance. The Panasonic part provides tighter resistance accuracy, which is beneficial for precision analog circuits and measurement applications.

Q: Does the temperature coefficient difference matter for my application?

A: Temperature coefficient affects resistance stability across temperature ranges. The ERA-8AEB432V (±25ppm/°C) provides better temperature stability than the RT1206FRE074K3L (±50ppm/°C). For applications operating across the full -55°C to 155°C range, the lower coefficient reduces resistance drift.

Q: Is the AEC-Q200 certification important?

A: AEC-Q200 certification indicates the component meets automotive industry reliability and quality standards. This certification is required for automotive applications and recommended for industrial or mission-critical applications. For general consumer electronics, it is not mandatory but represents higher quality assurance.

Q: Are the physical dimensions identical?

A: Both parts use the 1206 (3216 Metric) package. Minor dimensional variations exist within the package specification: RT1206FRE074K3L is 3.10mm × 1.60mm, while ERA-8AEB432V is 3.20mm × 1.60mm. These differences are within package tolerance and do not affect PCB layout compatibility.

Q: What is the moisture sensitivity level, and why is it important?

A: Both parts have MSL 1 (Unlimited), meaning they have unlimited shelf life and do not require special moisture control during storage or handling. This simplifies supply chain management and reduces component preparation requirements.
