RT1206FRE07143RL Equivalent & Substitute Parts

Part Overview

The RT1206FRE07143RL is a 143 Ohms ±1% thin film chip resistor manufactured by YAGEO in the 1206 (3216 Metric) package format. This surface mount device is rated for 0.25W (1/4W) power dissipation and operates across the temperature range of -55°C to 155°C. The part maintains Active product status with full RoHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Finding equivalent and substitute parts is necessary to ensure design flexibility, manage supply chain continuity, and optimize cost-performance trade-offs in production environments.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RT1206FRE07143RL is determined by the following critical parameters:

• Resistance Value: Must be 143 Ohms
• Package Format: Must be 1206 (3216 Metric) to ensure PCB footprint compatibility
• Power Rating: Must be rated for minimum 0.25W (1/4W)
• Composition: Thin film construction maintains performance characteristics
• Operating Temperature Range: Must support -55°C to 155°C minimum
• Compliance: RoHS3 compliance and MSL 1 rating required

The ERA-8AEB1430V from Panasonic Electronic Components qualifies as a direct substitute. While it offers improved tolerance (±0.1% versus ±1%) and lower temperature coefficient (±25ppm/°C versus ±50ppm/°C), these represent performance enhancements rather than deviations from the core electrical and mechanical requirements.

Parameter Comparison

Engineering Selection Recommendations

Both the RT1206FRE07143RL and ERA-8AEB1430V meet the core electrical and mechanical requirements for 143 Ohm 1206 thin film resistor applications. Selection between these parts should be based on application-specific requirements:

The RT1206FRE07143RL is suitable for general-purpose applications where standard ±1% tolerance and ±50ppm/°C temperature coefficient are acceptable.

The ERA-8AEB1430V is appropriate for applications requiring tighter tolerance control (±0.1%) and improved temperature stability (±25ppm/°C). The AEC-Q200 automotive qualification indicates suitability for automotive and high-reliability environments where enhanced performance margins are beneficial.

Both parts maintain identical RoHS3 compliance, MSL 1 rating, and operating temperature range, ensuring regulatory and environmental compatibility across applications.

Frequently Asked Questions (FAQ)

Q: Can ERA-8AEB1430V replace RT1206FRE07143RL in existing designs?

A: Yes. Both parts share identical resistance value (143 Ohms), package format (1206), power rating (0.25W), and operating temperature range (-55°C to 155°C). The ERA-8AEB1430V offers improved tolerance and temperature coefficient, making it a direct electrical and mechanical substitute.

Q: What are the physical dimension differences between these parts?

A: The RT1206FRE07143RL measures 0.122" L × 0.063" W (3.10mm × 1.60mm) with maximum seated height of 0.026" (0.65mm). The ERA-8AEB1430V measures 0.126" L × 0.063" W (3.20mm × 1.60mm) with maximum seated height of 0.028" (0.70mm). These minor dimensional variations remain within standard 1206 package tolerances and do not affect PCB footprint compatibility.

Q: Are there compliance or certification differences?

A: Both parts are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating. The ERA-8AEB1430V carries AEC-Q200 automotive qualification, which is not specified for the RT1206FRE07143RL. This qualification indicates enhanced reliability testing and is beneficial for automotive and mission-critical applications.

Q: Which part should be selected for cost optimization?

A: Selection should be based on application requirements rather than cost alone. The RT1206FRE07143RL may offer cost advantages in applications where ±1% tolerance is sufficient. The ERA-8AEB1430V justifies its cost through improved tolerance and temperature stability in precision-sensitive or automotive applications.

Q: Are both parts available in Tape & Reel packaging?

A: Yes. Both the RT1206FRE07143RL and ERA-8AEB1430V are supplied in Tape & Reel (TR) format, suitable for automated assembly processes.
