RE0805FRE075K1L Equivalent & Substitute Parts

Part Overview

The RE0805FRE075K1L is a 5.1 kOhms ±1% thick film chip resistor manufactured by YAGEO in 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 dimensions, and operating parameters align within acceptable electrical and mechanical tolerances for this resistor category.

Substitute Part Grouping Explanation

Substitute parts for the RE0805FRE075K1L are qualified based on the following criteria:

Mandatory Matching Parameters:

• Resistance value: 5.1 kOhms (exact match)
• Package / Case: 0805 (2012 Metric) (exact match)
• Composition: Thick Film
• Temperature Coefficient: ±50ppm/°C
• Operating Temperature Range: -55°C ~ 155°C (minimum)
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Allowable Variations:

• Tolerance: May be equal to or tighter than ±1%
• Power Rating: May be equal to or greater than 0.125W (1/8W)
• Manufacturer: Different manufacturer acceptable if all parameters align

The identified substitutes (ERJ-PB6B5101V and ERJ-PB6D5101V) meet all mandatory parameters. Both are manufactured by Panasonic Electronic Components with improved tolerance specifications (±0.1% and ±0.5% respectively) and higher power ratings (0.25W / 1/4W), making them suitable drop-in replacements.

Parameter Comparison

Engineering Selection Recommendations

Both Panasonic substitutes maintain Active product status and ROHS3 compliance, matching the original part's regulatory requirements. The ERJ-PB6B5101V and ERJ-PB6D5101V are qualified to AEC-Q200 automotive standards, providing additional qualification beyond the base RE0805FRE075K1L specification. The increased power rating (0.25W versus 0.125W) and improved tolerance specifications (±0.1% and ±0.5% versus ±1%) represent enhanced electrical performance characteristics. Height variation (0.028" maximum versus 0.024" maximum) remains within typical PCB assembly tolerances for 0805 components. Selection between the two Panasonic options depends on tolerance requirements: ERJ-PB6B5101V for applications requiring ±0.1% precision, or ERJ-PB6D5101V for applications requiring ±0.5% tolerance with lower cost.

Frequently Asked Questions (FAQ)

Q: Can ERJ-PB6B5101V and ERJ-PB6D5101V be used interchangeably with RE0805FRE075K1L?

A: Yes. Both Panasonic parts match the mandatory electrical and mechanical parameters: 5.1 kOhms resistance, 0805 package, thick film composition, ±50ppm/°C temperature coefficient, and -55°C to 155°C operating range. The improved tolerance and power ratings represent enhanced specifications suitable for direct substitution.

Q: What is the significance of the height difference (0.024" versus 0.028")?

A: The 0.004" (0.10mm) height increase in the Panasonic substitutes falls within standard PCB assembly tolerances for 0805 components and does not affect mechanical compatibility or board-level assembly processes.

Q: Why do the substitute parts have AEC-Q200 automotive qualification?

A: AEC-Q200 is an automotive industry qualification standard. The Panasonic ERJ-PB6 series includes this certification as part of the product line specification. This additional qualification does not restrict use in non-automotive applications.

Q: How do tolerance differences affect circuit performance?

A: The RE0805FRE075K1L specifies ±1% tolerance, while ERJ-PB6B5101V offers ±0.1% and ERJ-PB6D5101V offers ±0.5%. Tighter tolerance specifications reduce resistance value variation across production batches. Selection depends on circuit requirements: applications sensitive to resistance variation benefit from tighter tolerance parts, while general-purpose applications function equivalently across all three options.

Q: Are there any packaging or handling differences?

A: All three parts are supplied in Tape & Reel (TR) packaging with MSL Level 1 (Unlimited) moisture sensitivity rating, indicating identical handling and storage requirements.
