RC5025F1473CS Equivalent & Substitute Parts

Part Overview

The RC5025F1473CS is a 147 kOhm ±1% thick film chip resistor manufactured by Samsung Electro-Mechanics, rated at 0.667W (2/3W) in a 2010 (5025 Metric) package. This component is currently in active production status with moisture-resistant construction and operates across the temperature range of -55°C to 155°C. The part is ROHS3 compliant and carries MSL Level 1 (unlimited moisture sensitivity rating).

Equivalent and substitute parts are identified when design requirements permit tolerance of minor variations in power rating, product status, or specific feature sets while maintaining core electrical and mechanical compatibility within the 2010 package footprint.

Substitute Part Grouping Explanation

Substitution of the RC5025F1473CS is determined by strict alignment of the following core parameters:

Mandatory Matching Parameters:

• Resistance value: 147 kOhms
• Tolerance: ±1%
• Package / Case: 2010 (5025 Metric)
• Composition: Thick Film
• Temperature Coefficient: ±100ppm/°C
• Operating Temperature Range: -55°C to 155°C
• Number of Terminations: 2
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: MSL 1

Allowable Variation Parameters:

• Power Rating: Substitutes with equal or higher power rating (0.667W minimum)
• Product Status: Active or Not For New Designs
• Specific Features: Moisture Resistant or Automotive AEC-Q200 certifications

The identified substitute ERJ-12SF1473U meets all mandatory parameters with a higher power rating of 0.75W (3/4W) and includes automotive AEC-Q200 qualification, making it suitable for applications where the original part's specifications are met or exceeded.

Parameter Comparison

Engineering Selection Recommendations

RC5025F1473CS (Primary Selection): The RC5025F1473CS remains the preferred choice for new designs due to its active product status. This Samsung component provides the specified 0.667W power rating with moisture-resistant construction and full ROHS3 compliance. Selection of this part is appropriate for standard industrial and consumer applications requiring the exact power rating specified.

ERJ-12SF1473U (Substitute Selection): The ERJ-12SF1473U from Panasonic serves as a functional equivalent with the following considerations: The part carries "Not For New Designs" status, indicating it is in mature or declining production phase. However, it provides a higher power rating of 0.75W, which accommodates applications where thermal margin is beneficial. The automotive AEC-Q200 qualification indicates enhanced reliability screening and is suitable for automotive or mission-critical applications. The marginal height increase (0.028" vs 0.026") remains within typical PCB assembly tolerances for 2010 package components.

Selection of ERJ-12SF1473U is appropriate when: existing inventory of RC5025F1473CS is unavailable, higher power dissipation capability is required, or automotive-grade reliability is mandated by application requirements.

Frequently Asked Questions (FAQ)

Q: Can ERJ-12SF1473U directly replace RC5025F1473CS on existing PCBs?

A: Yes. Both components share identical footprints in the 2010 (5025 Metric) package with matching lead spacing and termination count. The height difference of 0.002" (0.04mm) is negligible for standard reflow soldering processes and does not affect PCB assembly compatibility.

Q: What is the significance of the "Not For New Designs" status on ERJ-12SF1473U?

A: This designation indicates the part is in mature production phase and may have limited long-term availability. For new product development, RC5025F1473CS is recommended due to its active status. ERJ-12SF1473U is suitable for replacement, repair, or applications where existing supply chains are established.

Q: Are there electrical performance differences between these parts?

A: Both parts share identical resistance value (147 kOhms), tolerance (±1%), temperature coefficient (±100ppm/°C), and operating temperature range (-55°C to 155°C). The primary difference is power rating: RC5025F1473CS is rated at 0.667W while ERJ-12SF1473U is rated at 0.75W. This means ERJ-12SF1473U can dissipate higher power without exceeding temperature limits.

Q: Do both parts meet the same compliance standards?

A: Yes. Both RC5025F1473CS and ERJ-12SF1473U are ROHS3 compliant, carry MSL Level 1 (unlimited moisture sensitivity), and are REACH unaffected. Both are classified under ECCN EAR99 and HTSUS 8533.21.0030.

Q: Which part should be selected for automotive applications?

A: ERJ-12SF1473U includes AEC-Q200 automotive qualification, making it the specified choice for automotive-grade designs. RC5025F1473CS does not carry this certification and should not be used in applications requiring automotive reliability standards.

Q: What is the packaging difference between these parts?

A: RC5025F1473CS is supplied in standard packaging format. ERJ-12SF1473U is supplied in Tape & Reel (TR) format, which is standard for high-volume automated assembly. Both are compatible with pick-and-place equipment and standard reflow processes.
