Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC5025F1820CS is determined by strict adherence to the following critical parameters:

Electrical Compatibility Requirements:

• Resistance value must be 182 Ohms
• Tolerance must be ±1% or tighter
• Power rating must be equal to or greater than 0.667W
• Temperature coefficient must be ±100ppm/°C or better
• Operating temperature range must encompass -55°C to 155°C

Mechanical Compatibility Requirements:

• Package format must be 2010 (5025 Metric)
• Physical dimensions must match: 0.197" L x 0.098" W (5.00mm x 2.50mm)
• Number of terminations must be 2

Compliance Requirements:

• RoHS3 compliance mandatory
• Moisture Sensitivity Level MSL 1 or equivalent
• REACH Unaffected status

The RMCF2010FT182R from Stackpole Electronics Inc satisfies all substitution criteria. This part maintains identical resistance, tolerance, package geometry, and environmental specifications while providing a higher power rating (0.75W versus 0.667W), which represents a conservative design margin without introducing incompatibility.

Engineering Selection Recommendations

Primary Selection: RC5025F1820CS

The RC5025F1820CS remains the primary component choice when Samsung Electro-Mechanics supply is available. This part carries Active product status with full ROHS3 compliance and unlimited moisture sensitivity rating, suitable for standard industrial and commercial applications.

Substitute Selection: RMCF2010FT182R

The RMCF2010FT182R from Stackpole Electronics Inc is a qualified substitute when RC5025F1820CS availability is constrained. This part meets all electrical and mechanical compatibility requirements with the following additional attributes:

• AEC-Q200 automotive qualification provides enhanced reliability documentation
• 0.75W power rating exceeds the 0.667W requirement, offering design margin
• Identical package footprint (2010/5025 Metric) ensures PCB layout compatibility
• Active product status with ROHS3 compliance maintains regulatory alignment
• Tape & Reel packaging supports automated assembly processes

Both parts are suitable for direct substitution in applications where the specified electrical parameters and environmental operating conditions are maintained.

Frequently Asked Questions (FAQ)

Q: Can RMCF2010FT182R replace RC5025F1820CS in existing designs?

A: Yes. The RMCF2010FT182R is electrically and mechanically compatible. Both parts share identical resistance (182 Ohms), tolerance (±1%), package format (2010/5025 Metric), temperature coefficient (±100ppm/°C), and operating temperature range (-55°C to 155°C). The substitute part's higher power rating (0.75W versus 0.667W) does not create incompatibility.

Q: What are the physical footprint differences?

A: Both parts use the 2010 (5025 Metric) package with identical length and width dimensions (0.197" L x 0.098" W / 5.00mm x 2.50mm). Maximum seated height differs slightly: RC5025F1820CS at 0.026" (0.66mm) and RMCF2010FT182R at 0.028" (0.70mm). This 0.002" (0.04mm) difference is within standard PCB assembly tolerances and does not affect placement or soldering.

Q: Are both parts RoHS compliant?

A: Yes. Both RC5025F1820CS and RMCF2010FT182R carry ROHS3 compliance certification and REACH Unaffected status, meeting current environmental and regulatory requirements.

Q: What is the significance of the AEC-Q200 rating on the substitute part?

A: AEC-Q200 is an automotive qualification standard indicating enhanced reliability testing and quality documentation. While the main part (RC5025F1820CS) does not carry this designation, the substitute part's AEC-Q200 rating provides additional reliability assurance without introducing incompatibility.

Q: Can these parts be used interchangeably in automated assembly?

A: Yes. Both parts are available in standard packaging formats compatible with automated pick-and-place equipment. The RC5025F1820CS is available in standard packaging, while RMCF2010FT182R is supplied in Tape & Reel format, both suitable for high-volume assembly processes.

Q: What determines substitution eligibility for 2010 package resistors?

A: Substitution eligibility is determined by: (1) identical resistance value and tolerance, (2) equal or higher power rating, (3) matching package dimensions and termination count, (4) identical or superior temperature coefficient, (5) operating temperature range that encompasses the original specification, and (6) equivalent or superior compliance certifications (RoHS, REACH, MSL).
