Substitute Part Grouping Explanation

Substitution eligibility for the RMCS0805FT2K26 is determined by strict equivalence across the following critical parameters:

• Resistance Value: 2.26 kOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Power Rating: 0.125W / 1/8W (exact match required)
• Package / Case: 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)
• Moisture Sensitivity Level: 1 (Unlimited) (exact match required)

All four substitute parts listed below meet these core electrical and mechanical requirements. Differences in physical height, manufacturer-specific features (such as automotive AEC-Q200 certification or moisture resistance), and regional compliance status do not affect functional interchangeability in standard applications.

Parameter Comparison

Engineering Selection Recommendations

All four substitute parts are functionally equivalent to the RMCS0805FT2K26 based on core electrical and mechanical parameters. Selection among these alternatives should be based on application-specific compliance and certification requirements:

CRCW08052K26FKEA (Vishay Dale) is suitable for applications requiring automotive AEC-Q200 qualification with full RoHS3 compliance and REACH unaffected status. This part offers the lowest seated height at 0.020" (0.50mm).

CRCW08052K26FKTA (Vishay Dale) provides automotive AEC-Q200 qualification but carries RoHS non-compliance and REACH affected status. This variant is restricted to applications where such compliance limitations are acceptable.

ERJ-6ENF2261V (Panasonic) is qualified to automotive AEC-Q200 standards with full RoHS3 compliance and REACH unaffected status. This part has the highest seated height at 0.028" (0.70mm), which may be a consideration in space-constrained designs.

RC0805FR-072K26L (YAGEO) offers moisture-resistant thick film construction with RoHS3 compliance and REACH unaffected status. This part matches the seated height of the original RMCS0805FT2K26 at 0.024" (0.60mm) and is suitable for general-purpose applications without automotive certification requirements.

Frequently Asked Questions (FAQ)

Q: Can I use any of these substitute parts interchangeably with the RMCS0805FT2K26?

A: Yes, all four substitute parts are electrically and mechanically equivalent based on resistance value, tolerance, power rating, package type, composition, temperature coefficient, and operating temperature range. Physical height variations are minor and typically do not affect PCB layout compatibility in standard applications.

Q: What is the difference between the two Vishay Dale variants (CRCW08052K26FKEA and CRCW08052K26FKTA)?

A: Both parts are identical in electrical specifications and automotive AEC-Q200 qualification. The primary difference is compliance status: CRCW08052K26FKEA is RoHS3 compliant and REACH unaffected, while CRCW08052K26FKTA is RoHS non-compliant and REACH affected. Selection depends on regional regulatory requirements.

Q: Why do the substitute parts have different seated heights?

A: Seated height variation is a manufacturer-specific design characteristic that does not affect electrical performance. Heights range from 0.020" (0.50mm) to 0.028" (0.70mm). Verify PCB clearance requirements for your specific application before selection.

Q: Which substitute part should I choose for automotive applications?

A: CRCW08052K26FKEA, CRCW08052K26FKTA, and ERJ-6ENF2261V all carry automotive AEC-Q200 qualification. Choose based on compliance requirements: CRCW08052K26FKEA and ERJ-6ENF2261V for full RoHS3 compliance, or CRCW08052K26FKTA if compliance limitations are acceptable.

Q: Is the RMCS0805FT2K26 still in production?

A: Yes, the RMCS0805FT2K26 is actively produced by Stackpole Electronics Inc. All substitute parts are also in active production status.

Q: What does Moisture Sensitivity Level 1 mean?

A: MSL 1 (Unlimited) indicates that the component has unlimited shelf life and requires no special moisture control during storage or handling. All parts listed, including the main part and substitutes, carry this rating.
