RE0805FRE07124KL Equivalent & Substitute Parts

Part Overview

The RE0805FRE07124KL is a 124 kOhms ±1% thick film chip resistor manufactured by YAGEO in the 0805 (2012 Metric) package format. This component is rated for 0.125W (1/8W) power dissipation with an operating temperature range of -55°C to 155°C. The part maintains Active product status and is ROHS3 compliant with MSL Level 1 (Unlimited moisture sensitivity).

Substitute parts are identified when equivalent resistance values, package formats, and thermal operating ranges are maintained while allowing variations in tolerance specifications and power ratings that remain within acceptable application parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RE0805FRE07124KL is determined by the following mandatory parameters:

• Resistance value: 124 kOhms (exact match required)
• Package format: 0805 (2012 Metric) (exact match required)
• Composition: Thick Film (exact match required)
• Operating temperature range: -55°C ~ 155°C (minimum requirement)
• Temperature coefficient: ±50ppm/°C (exact match required)
• RoHS compliance: ROHS3 Compliant (minimum requirement)

Tolerance and power rating may vary from the original specification provided the substitute part maintains or exceeds the original electrical performance envelope. Both identified substitutes meet these criteria while offering enhanced specifications in tolerance (±0.1% and ±0.5% versus ±1%) and power rating (0.25W versus 0.125W).

Parameter Comparison

Engineering Selection Recommendations

Both Panasonic ERJ-PB6 series substitutes maintain full compatibility with the RE0805FRE07124KL across all critical electrical and mechanical parameters. Selection between substitutes depends on application-specific requirements:

ERJ-PB6B1243V offers the tightest tolerance specification at ±0.1%, suitable for precision analog circuits requiring minimal resistance variation. This part carries AEC-Q200 automotive qualification.

ERJ-PB6D1243V provides a balanced tolerance of ±0.5% with higher inventory availability (28,851 units in stock) and identical AEC-Q200 automotive qualification. This part represents the most readily available substitute option.

Both substitutes provide doubled power dissipation capacity (0.25W versus 0.125W), enhancing thermal margin in the application. All parts maintain identical operating temperature ranges, temperature coefficients, and RoHS compliance status.

Frequently Asked Questions (FAQ)

Q: Can ERJ-PB6B1243V or ERJ-PB6D1243V be used as direct replacements for RE0805FRE07124KL?

A: Yes. Both Panasonic parts are direct substitutes. They maintain identical resistance values, package formats, operating temperature ranges, and temperature coefficients. The enhanced tolerance and power ratings of the substitutes provide equal or superior performance in standard applications.

Q: What is the significance of the tolerance difference between ±1% and ±0.1% or ±0.5%?

A: Tolerance defines the maximum deviation from the nominal 124 kOhms resistance value. The original part allows ±1,240 ohms deviation. ERJ-PB6B1243V limits deviation to ±124 ohms, while ERJ-PB6D1243V limits it to ±620 ohms. Tighter tolerance is beneficial in precision circuits but not required for general-purpose applications.

Q: Why do the substitute parts have higher power ratings?

A: The Panasonic ERJ-PB6 series is rated for 0.25W (1/4W) versus the YAGEO RE series 0.125W (1/8W). Higher power rating provides additional thermal margin and does not negatively impact circuit performance. The component will dissipate only the power required by the circuit, regardless of its rated capacity.

Q: Are the substitute parts suitable for automotive applications?

A: Both Panasonic substitutes carry AEC-Q200 automotive qualification. The original YAGEO part does not specify this rating. If automotive qualification is required, the Panasonic substitutes are appropriate selections.

Q: What is the physical size difference between these parts?

A: All three parts use the 0805 (2012 Metric) package with identical length (0.079" / 2.00mm) and width (0.049" / 1.25mm). The Panasonic substitutes have a maximum seated height of 0.028" (0.70mm) versus the YAGEO part at 0.024" (0.60mm). This 0.004" difference is negligible for standard PCB assembly.

Q: Can these parts be used interchangeably in existing designs?

A: Yes. The identical package format, footprint, and electrical characteristics ensure mechanical and electrical interchangeability. No PCB redesign or circuit modification is required.
