Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RMCS0805FT8K25 is determined by strict equivalence across the following parameters:

• Resistance value: 8.25 kOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Power rating: 0.125W / 1/8W (exact match required)
• Package: 0805 (2012 Metric) (exact match required)
• Composition: Thick Film (exact match required)
• Temperature coefficient: ±100ppm/°C (exact match required)
• Operating temperature range: -55°C ~ 155°C (exact match required)
• Termination count: 2 (exact match required)

All substitute parts listed meet these core electrical and mechanical parameters. Variations in packaging format (Tape & Reel vs. Cut Tape), manufacturer-specific features (AEC-Q200 automotive certification, anti-sulfur, moisture resistant), and physical dimensions (height seated) do not affect functional substitutability but may influence application suitability and compliance requirements.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts are functionally equivalent to the RMCS0805FT8K25 based on core electrical and mechanical parameters. Selection among substitutes should be based on the following criteria:

Compliance Requirements: For applications requiring ROHS3 compliance, RMCF0805FT8K25, AC0805FR-078K25L, CRCW08058K25FKEA, ERJ-6ENF8251V, and RC0805FR-078K25L are suitable. CRCW08058K25FKTA is RoHS non-compliant and REACH affected, limiting its use in regulated applications.

Automotive Applications: RMCF0805FT8K25, AC0805FR-078K25L, CRCW08058K25FKEA, CRCW08058K25FKTA, and ERJ-6ENF8251V carry AEC-Q200 automotive certification. These parts are appropriate for automotive-grade circuit designs.

Packaging Format: Tape & Reel format is available from Stackpole (RMCF0805FT8K25), YAGEO (AC0805FR-078K25L, RC0805FR-078K25L), and Vishay Dale (CRCW08058K25FKTA). Cut Tape & Digi-Reel format is available from Vishay Dale (CRCW08058K25FKEA) and Panasonic (ERJ-6ENF8251V).

Physical Dimensions: Height seated varies from 0.50mm (Vishay Dale CRCW series) to 0.70mm (Panasonic ERJ-6EN series). Applications with tight PCB clearance constraints should reference specific height specifications.

Inventory Availability: Highest stock levels are available from YAGEO RC0805FR-078K25L (90,971 pcs) and Panasonic ERJ-6ENF8251V (62,779 pcs).

Frequently Asked Questions (FAQ)

Q: Can I substitute RMCS0805FT8K25 with any of the listed parts without circuit redesign?

A: Yes. All listed parts meet the core electrical parameters (8.25 kΩ, ±1%, 0.125W, 0805 package, thick film, ±100ppm/°C, -55°C ~ 155°C). Physical height variations are minor and do not typically require PCB redesign for standard applications.

Q: What is the difference between Tape & Reel and Cut Tape & Digi-Reel packaging?

A: Tape & Reel packaging is continuous reel format suitable for high-volume automated assembly. Cut Tape & Digi-Reel is pre-cut tape on a reel, offering flexibility for lower-volume or mixed-component orders. Both formats contain the same component; packaging choice depends on manufacturing process requirements.

Q: Why is CRCW08058K25FKTA marked as RoHS non-compliant?

A: CRCW08058K25FKTA does not meet ROHS3 compliance standards and is REACH affected. This part should not be used in applications subject to RoHS or REACH regulations. Use CRCW08058K25FKEA (RoHS compliant) as the alternative from Vishay Dale.

Q: Are AEC-Q200 certified parts required for my application?

A: AEC-Q200 certification is required only for automotive applications. For general industrial or consumer electronics, non-automotive certified parts (RMCS0805FT8K25, RC0805FR-078K25L) are functionally equivalent and may offer cost advantages.

Q: What does ±100ppm/°C temperature coefficient mean?

A: Temperature coefficient specifies resistance change per degree Celsius. ±100ppm/°C means the resistance value can drift up to 100 parts per million per degree of temperature change. All listed parts share this specification, ensuring consistent thermal performance across the operating range of -55°C to 155°C.

Q: Can I mix different manufacturers' parts in the same circuit board?

A: Yes. All substitute parts meet identical electrical specifications and package dimensions. Mixing manufacturers is acceptable from an electrical standpoint. However, for manufacturing traceability and quality control, many organizations prefer single-source components within a design.
