RT1206FRE07158RL Equivalent & Substitute Parts

Part Overview

The RT1206FRE07158RL is a 158 Ohm ±1% thin film chip resistor in 1206 (3216 Metric) package format, rated for 0.25W (1/4W) power dissipation. This YAGEO component operates across -55°C to 155°C and is ROHS3 compliant with unlimited moisture sensitivity rating (MSL 1). The part is currently active in production with 861 pieces in stock.

Equivalent and substitute parts are identified when they maintain identical resistance values, package dimensions, power ratings, and operating temperature ranges while potentially offering improved tolerance specifications or enhanced reliability certifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RT1206FRE07158RL is determined by strict adherence to the following parameters:

• Resistance value must be exactly 158 Ohms
• Package must be 1206 (3216 Metric) with compatible footprint dimensions
• Power rating must be 0.25W (1/4W) minimum
• Operating temperature range must encompass -55°C to 155°C
• Composition must be thin film
• RoHS3 compliance and MSL 1 rating required

The identified substitute parts meet all mandatory parameters. Tolerance specifications may be tighter (±0.1% versus ±1%), and temperature coefficients may be lower, representing performance enhancements rather than functional deviations.

Parameter Comparison

Engineering Selection Recommendations

Both RT1206BRD07158RL and ERA-8AEB1580V are functionally equivalent to RT1206FRE07158RL for applications requiring 158 Ohm thin film resistors in 1206 package format.

RT1206BRD07158RL offers improved tolerance (±0.1% versus ±1%) and lower temperature coefficient (±25ppm/°C versus ±50ppm/°C) while maintaining identical package dimensions and power rating. Both parts are YAGEO products with active production status and ROHS3 compliance.

ERA-8AEB1580V provides equivalent electrical performance with ±0.1% tolerance and ±25ppm/°C temperature coefficient. This Panasonic component includes AEC-Q200 automotive qualification, suitable for applications requiring automotive-grade reliability. Physical dimensions are within acceptable tolerance (3.20mm L × 1.60mm W versus 3.10mm L × 1.60mm W for the main part), and height is marginally increased (0.70mm versus 0.65mm seated height).

Frequently Asked Questions (FAQ)

Q: Can RT1206BRD07158RL directly replace RT1206FRE07158RL in existing designs?

A: Yes. Both parts share identical resistance value, power rating, package footprint, and operating temperature range. The tighter tolerance (±0.1%) and lower temperature coefficient of RT1206BRD07158RL represent performance improvements with no functional incompatibility.

Q: Is ERA-8AEB1580V compatible with standard 1206 PCB footprints?

A: Yes. ERA-8AEB1580V uses the 1206 (3216 Metric) package with compatible footprint dimensions. The physical size difference (3.20mm L × 1.60mm W versus 3.10mm L × 1.60mm W) falls within standard PCB design tolerances for 1206 components.

Q: What is the significance of AEC-Q200 qualification on ERA-8AEB1580V?

A: AEC-Q200 is an automotive industry standard qualification. ERA-8AEB1580V meets enhanced reliability and testing requirements for automotive applications. This certification is not required for general industrial or consumer applications but provides additional assurance for automotive-grade designs.

Q: Are all three parts ROHS3 compliant?

A: Yes. RT1206FRE07158RL, RT1206BRD07158RL, and ERA-8AEB1580V are all ROHS3 compliant with MSL 1 (unlimited) moisture sensitivity rating.

Q: What is the practical difference between ±1% and ±0.1% tolerance?

A: For a 158 Ohm resistor, ±1% tolerance allows ±1.58 Ohm variation (156.42 to 159.58 Ohms), while ±0.1% tolerance allows ±0.158 Ohm variation (157.842 to 158.158 Ohms). Tighter tolerance is beneficial in precision analog circuits, measurement equipment, and applications with strict impedance matching requirements.
