RC2010FK-07105RL Equivalent & Substitute Parts

Part Overview

The RC2010FK-07105RL is a 105 Ohm ±1% thick film chip resistor rated at 0.75W in a 2010 (5025 Metric) surface mount package. Manufactured by YAGEO under the RC_L series, this component is currently in active production status with moisture resistant properties and unlimited moisture sensitivity level (MSL 1).

Substitute parts are necessary when the primary manufacturer experiences supply constraints, when design requirements mandate specific certifications such as automotive qualification, or when alternative sourcing improves cost efficiency while maintaining electrical and mechanical compatibility.

Substitute Part Grouping Explanation

Substitution eligibility for the RC2010FK-07105RL is determined by strict equivalence across the following parameters:

• Resistance value: 105 Ohms
• Tolerance: ±1%
• Power rating: 0.75W minimum
• Package: 2010 (5025 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C minimum
• RoHS3 compliance
• MSL rating: 1 or equivalent

The ERJ-12SF1050U from Panasonic Electronic Components meets all electrical and mechanical substitution criteria. This part maintains identical resistance, tolerance, power rating, package dimensions, and thermal specifications. The primary distinction is the inclusion of AEC-Q200 automotive qualification, which represents an additional certification layer rather than a deviation from base specifications.

Parameter Comparison

Engineering Selection Recommendations

The RC2010FK-07105RL remains the primary selection for new designs due to its active production status. The component is fully compliant with ROHS3 requirements and carries unlimited moisture sensitivity rating, suitable for standard industrial and commercial applications.

The ERJ-12SF1050U serves as a direct electrical and mechanical substitute when supply of the primary part is unavailable. This Panasonic component carries AEC-Q200 automotive qualification, making it suitable for automotive applications where such certification is mandated. However, its "Not For New Designs" status indicates that Panasonic is phasing this part from active production. Selection of ERJ-12SF1050U should be limited to replacement or continuation of existing designs where automotive qualification is a requirement.

Both parts are electrically and mechanically interchangeable within the specified parameter tolerances. The maximum seated height difference of 0.002" (0.05mm) between the two parts is within typical PCB assembly tolerances and does not present a functional constraint.

Frequently Asked Questions (FAQ)

Q: Can ERJ-12SF1050U be used as a direct replacement for RC2010FK-07105RL in all applications?

A: Yes, within the electrical and mechanical specifications provided. Both parts share identical resistance, tolerance, power rating, package dimensions, and thermal characteristics. The height difference of 0.002" is negligible for standard PCB assembly processes.

Q: What is the significance of the AEC-Q200 rating on the ERJ-12SF1050U?

A: AEC-Q200 is an automotive industry qualification standard. This certification indicates the part meets automotive reliability and quality requirements. If your application does not require automotive qualification, this additional certification does not affect substitution eligibility.

Q: Why is the ERJ-12SF1050U marked "Not For New Designs"?

A: This status indicates Panasonic is discontinuing this part number from active production. While it remains available for existing designs and replacements, new designs should prioritize the RC2010FK-07105RL or identify alternative long-term sources.

Q: Are there any PCB layout or assembly considerations when switching between these parts?

A: Both parts use identical 2010 (5025 Metric) package footprints. The maximum seated height difference of 0.028" versus 0.026" is within standard PCB assembly tolerances and requires no layout modifications.

Q: Do both parts meet the same environmental and compliance standards?

A: Yes. Both RC2010FK-07105RL and ERJ-12SF1050U are ROHS3 compliant, carry MSL 1 (Unlimited) moisture sensitivity rating, and operate across the identical temperature range of -55°C to 155°C.
