RE0805FRE077K5L Equivalent & Substitute Parts

Part Overview

The RE0805FRE077K5L is a 7.5 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 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). Substitute parts are identified when equivalent electrical specifications and mechanical compatibility can be maintained within the allowed parameter tolerances for this resistor category.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RE0805FRE077K5L is determined by the following critical parameters:

• Resistance Value: Must be 7.5 kOhms
• Package Format: Must be 0805 (2012 Metric) for mechanical and electrical compatibility
• Composition: Thick film construction
• Temperature Coefficient: ±50ppm/°C
• Operating Temperature Range: -55°C ~ 155°C minimum
• RoHS3 Compliance: Required for regulatory alignment
• Moisture Sensitivity: MSL 1 classification

The ERJ-PB6D7501V from Panasonic Electronic Components qualifies as a substitute part. While it features improved tolerance (±0.5% versus ±1%) and higher power rating (0.25W versus 0.125W), these represent enhanced specifications that maintain full backward compatibility. The identical resistance value, package format, temperature coefficient, operating range, and RoHS3 compliance establish direct substitutability.

Parameter Comparison

Engineering Selection Recommendations

Both the RE0805FRE077K5L and ERJ-PB6D7501V maintain Active product status with full RoHS3 compliance and REACH unaffected classification. The ERJ-PB6D7501V carries AEC-Q200 automotive qualification and pulse withstanding capability, making it suitable for applications requiring enhanced reliability margins. The improved tolerance specification (±0.5% versus ±1%) and doubled power rating (0.25W versus 0.125W) provide additional design headroom without introducing incompatibility. Selection between these parts should be based on application-specific requirements for tolerance precision, thermal dissipation capacity, and automotive qualification needs.

Frequently Asked Questions (FAQ)

Q: Can the ERJ-PB6D7501V directly replace the RE0805FRE077K5L in existing designs?

A: Yes. Both parts share identical resistance value (7.5 kOhms), package format (0805), temperature coefficient (±50ppm/°C), and operating range (-55°C ~ 155°C). The substitute part's improved tolerance and higher power rating represent enhanced specifications that maintain full backward compatibility.

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

A: Tolerance defines the maximum deviation from the nominal resistance value. The ERJ-PB6D7501V's ±0.5% tolerance provides tighter resistance control compared to the RE0805FRE077K5L's ±1% tolerance. This enhanced precision may be beneficial in applications with strict circuit performance requirements, though both parts meet the same operating temperature and coefficient specifications.

Q: Are there physical compatibility concerns between these parts?

A: Both parts use the 0805 (2012 Metric) package with identical length and width (0.079" x 0.049"). The maximum seated height differs slightly (0.024" for RE0805FRE077K5L versus 0.028" for ERJ-PB6D7501V), which remains within standard PCB design tolerances for 0805 components and presents no practical assembly or clearance issues.

Q: What does AEC-Q200 qualification mean for the ERJ-PB6D7501V?

A: AEC-Q200 is an automotive industry standard qualification that certifies component reliability under automotive operating conditions. This certification is relevant only if your application requires automotive-grade components. For non-automotive applications, both parts are functionally equivalent.

Q: How do the power ratings affect component selection?

A: The RE0805FRE077K5L is rated for 0.125W (1/8W) while the ERJ-PB6D7501V is rated for 0.25W (1/4W). If your circuit dissipates power within the 0.125W limit, either part is suitable. If thermal analysis indicates power dissipation approaching or exceeding 0.125W, the ERJ-PB6D7501V's higher rating provides additional thermal margin.
