Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RC5025F9533CS are qualified based on the following criteria:

Mandatory Matching Parameters:

• Resistance value: 953 kOhms
• Tolerance: ±1%
• Package / Case: 2010 (5025 Metric)
• Composition: Thick Film
• Temperature Coefficient: ±100ppm/°C
• Operating Temperature Range: -55°C ~ 155°C
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: MSL 1 (Unlimited)

Allowable Variation:

• Power Rating: Substitutes rated at 0.75W (3/4W) are acceptable as this represents increased thermal capability within the same package footprint
• Packaging Format: Original part supplied in standard packaging; substitutes available in Tape & Reel (TR) format
• Certifications: Automotive AEC-Q200 qualification is an additional feature in substitute parts, not a requirement for substitution

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: CRCW2010953KFKEF (Vishay Dale)

The CRCW2010953KFKEF maintains Active product status and provides identical electrical specifications with increased power rating (0.75W vs. 0.667W). The higher power rating offers thermal margin within the same 2010 package footprint. Automotive AEC-Q200 qualification is included, providing additional quality assurance for applications requiring automotive-grade components. This part is suitable for new designs and production applications.

Secondary Substitute: ERJ-12SF9533U (Panasonic Electronic Components)

The ERJ-12SF9533U meets all electrical and mechanical compatibility requirements with identical resistance, tolerance, temperature coefficient, and operating range. However, this part carries "Not For New Designs" product status, indicating it is in mature or declining production phase. This substitute is appropriate for legacy system maintenance, repair, or replacement applications where design continuity is required. New design implementations should prioritize the CRCW2010953KFKEF option.

Compliance Considerations:

All three parts maintain ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity rating, ensuring compatibility with standard handling and storage procedures. The 0.028" maximum seated height of substitute parts represents a 0.002" increase over the original RC5025F9533CS, which remains within typical PCB assembly tolerances for 2010 package components.

Frequently Asked Questions (FAQ)

Q: Can CRCW2010953KFKEF be used as a direct replacement for RC5025F9533CS?

A: Yes. Both parts share identical resistance (953 kOhms), tolerance (±1%), package footprint (2010/5025 Metric), composition (thick film), temperature coefficient (±100ppm/°C), and operating range (-55°C ~ 155°C). The CRCW2010953KFKEF provides higher power rating (0.75W vs. 0.667W), which is acceptable for substitution as it represents increased thermal capability.

Q: What is the difference between the 0.667W and 0.75W power ratings?

A: Power rating indicates maximum continuous power dissipation capability. The 0.75W rating of substitute parts provides additional thermal margin. If the original circuit design requires 0.667W or less, the 0.75W-rated substitute will operate within specification with improved thermal performance.

Q: Why is ERJ-12SF9533U marked "Not For New Designs"?

A: This designation indicates the part is in mature production phase and may have limited availability or planned discontinuation. For new product development, CRCW2010953KFKEF is the recommended substitute. ERJ-12SF9533U is appropriate for maintenance and repair of existing systems using this component.

Q: Are there height differences between these parts?

A: Yes. RC5025F9533CS has maximum seated height of 0.026" (0.66mm), while both substitute parts have maximum seated height of 0.028" (0.70mm). This 0.002" difference is within standard PCB assembly tolerances for 2010 package components and does not affect functionality or mounting compatibility.

Q: Do all three parts have the same moisture sensitivity requirements?

A: Yes. All three parts are rated MSL 1 (Unlimited), meaning they have unlimited shelf life under normal storage conditions and do not require special moisture-control handling procedures during assembly.

Q: What is the significance of AEC-Q200 qualification on CRCW2010953KFKEF?

A: AEC-Q200 is an automotive industry standard qualification for passive components. This certification indicates the part meets automotive-grade reliability and quality requirements. It is an additional feature that does not affect substitution compatibility but provides enhanced assurance for applications requiring automotive-grade components.

Q: Can these parts be used interchangeably in existing PCB designs?

A: Yes, provided the PCB layout accommodates the maximum seated height of 0.028" (0.70mm). The identical 2010 package footprint (0.197" L x 0.098" W) ensures mechanical compatibility. Electrical performance is equivalent across all three parts for the specified operating conditions.
