Key Parameters

Substitute Part Grouping Explanation

Substitution logic for the RC5025F1872CS is based on the following criteria:

Electrical Parameters (Mandatory Match):

• Resistance value: 18.7 kOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Temperature coefficient: ±100ppm/°C (exact match required)
• Operating temperature range: -55°C ~ 155°C (minimum requirement)

Mechanical Parameters (Mandatory Match):

• Package type: 2010 (5025 Metric) (exact match required for PCB compatibility)
• Number of terminations: 2 (exact match required)

Performance Parameters (Flexible):

• Power rating: 0.667W minimum (substitutes with 0.75W or higher are acceptable as they provide equal or superior thermal capability)
• Composition: Thick Film (exact match required for performance characteristics)

Compliance Parameters (Flexible):

• RoHS status: ROHS3 Compliant (all substitutes maintain this requirement)
• Moisture sensitivity: MSL 1 (all substitutes maintain this rating)
• Automotive qualification: Optional enhancement (AEC-Q200 available in substitutes)

All substitute parts listed meet or exceed the mandatory electrical and mechanical parameters of the primary part while maintaining full compatibility with the specified operating environment.

Engineering Selection Recommendations

Primary Substitute: CRCW201018K7FKEF (Vishay Dale)

The CRCW201018K7FKEF is the recommended primary substitute for the RC5025F1872CS. This part maintains all mandatory electrical and mechanical parameters while offering a higher power rating (0.75W vs. 0.667W), providing additional thermal margin. The component carries Active product status, ensuring continued availability and support. AEC-Q200 automotive qualification provides enhanced reliability documentation suitable for demanding applications. Packaging is supplied in Tape & Reel format with 8897 units in current inventory.

Secondary Substitute: ERJ-12SF1872U (Panasonic Electronic Components)

The ERJ-12SF1872U provides electrical and mechanical equivalence to the primary part with identical resistance, tolerance, temperature coefficient, and operating temperature range. Power rating is 0.75W, matching the Vishay alternative. AEC-Q200 automotive qualification is included. However, this part carries "Not For New Designs" product status, indicating it is in mature phase with potential future discontinuation. This substitute is suitable for legacy system maintenance and repair applications where supply of the primary part is unavailable. Current inventory shows 5439 units available.

Selection Criteria:

• For new designs and applications requiring long-term availability: Select CRCW201018K7FKEF
• For legacy system support and repair: ERJ-12SF1872U is acceptable if primary part is unavailable
• Both substitutes are suitable for applications requiring automotive-grade reliability
• All three parts maintain identical electrical performance within specified tolerances

Frequently Asked Questions (FAQ)

Q: Can CRCW201018K7FKEF be used as a direct replacement for RC5025F1872CS without circuit modification?

A: Yes. Both parts have identical resistance (18.7 kOhms), tolerance (±1%), temperature coefficient (±100ppm/°C), and operating temperature range (-55°C ~ 155°C). The 2010 package footprint is identical. The higher power rating (0.75W vs. 0.667W) in the Vishay part provides additional thermal capability without affecting circuit operation.

Q: What is the difference between the 2/3W and 3/4W power ratings?

A: The RC5025F1872CS is rated at 0.667W (2/3W), while the substitute parts are rated at 0.75W (3/4W). Both ratings refer to the maximum continuous power dissipation the resistor can handle. The 3/4W rating provides approximately 12% additional thermal capacity. For applications operating at or near the original 2/3W specification, either rating is acceptable.

Q: Are the physical dimensions identical between all three parts?

A: The length and width are identical: 0.197" L x 0.098" W (5.00mm x 2.50mm). Maximum seated height differs slightly: RC5025F1872CS is 0.026" (0.66mm), while both substitutes are 0.028" (0.70mm). This 0.002" difference is negligible for standard PCB assembly and does not affect footprint compatibility.

Q: What does "Not For New Designs" mean for the ERJ-12SF1872U?

A: This product status indicates the part is in mature/legacy phase. Panasonic continues to support existing inventory and applications, but the company does not recommend this part for new circuit designs. For new applications, the CRCW201018K7FKEF (Active status) is the preferred choice.

Q: Do all three parts meet RoHS and environmental compliance requirements?

A: Yes. All three parts are ROHS3 compliant, REACH unaffected, and carry MSL 1 (Unlimited) moisture sensitivity rating. All are suitable for applications requiring environmental compliance certification.

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

A: AEC-Q200 is an automotive industry standard qualification that certifies the component has undergone rigorous reliability testing including thermal cycling, humidity resistance, and electrical stability verification. The Vishay and Panasonic substitutes carry this qualification, while the Samsung primary part does not specify this rating. For automotive applications, the qualified substitutes provide documented reliability assurance.

Q: Can these parts be used interchangeably in existing inventory?

A: Yes, within the constraints of your supply chain and quality procedures. All three parts are electrically and mechanically equivalent for the specified application parameters. Verify that your procurement and quality documentation procedures permit cross-substitution before implementing inventory consolidation.
