RMCS0805FT205K Equivalent & Substitute Parts

Part Overview

The RMCS0805FT205K is a 205 kOhms ±1% 0.125W chip resistor in 0805 (2012 Metric) package manufactured by Stackpole Electronics Inc. This thick film resistor features anti-sulfur composition and operates across -55°C to 155°C. The part is active in production and RoHS3 compliant. Equivalent parts are necessary when the primary part experiences supply constraints, when specific certifications (such as AEC-Q200 automotive qualification) are required, or when alternative packaging formats better suit manufacturing processes.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RMCS0805FT205K is determined by strict equivalence across the following parameters: resistance value (205 kOhms), tolerance (±1%), power rating (0.125W), package type (0805 / 2012 Metric), composition (thick film), temperature coefficient (±100ppm/°C), operating temperature range (-55°C to 155°C), and compliance certifications (RoHS3, REACH Unaffected). All identified substitute parts meet these core electrical and mechanical requirements. Variations in features (anti-sulfur, automotive AEC-Q200, moisture resistant) and packaging format (Tape & Reel vs. Cut Tape) do not affect functional substitutability but may influence suitability for specific applications or manufacturing environments.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts are active products with RoHS3 compliance and REACH Unaffected status, ensuring regulatory alignment with the original RMCS0805FT205K.

RMCF0805FT205K (Stackpole Electronics Inc) is the manufacturer-recommended primary substitute. It maintains identical electrical specifications and shares the same manufacturer as the original part. This part includes automotive AEC-Q200 qualification, suitable for applications requiring automotive-grade reliability.

CRCW0805205KFKEA (Vishay Dale) offers the lowest seated height (0.020" / 0.50mm) and is available in higher inventory quantities. It includes AEC-Q200 automotive qualification and is supplied in Cut Tape & Digi-Reel® packaging, which may optimize certain manufacturing workflows.

ERJ-6ENF2053V (Panasonic Electronic Components) provides the highest inventory availability and includes AEC-Q200 automotive qualification. The seated height is 0.028" (0.70mm), which is the maximum among all options.

RC0805FR-07205KL (YAGEO) features moisture-resistant composition and maintains the same seated height as the original part (0.024" / 0.60mm). This option is suitable for applications in humid environments.

Selection should prioritize inventory availability, packaging format requirements, and application-specific certifications. All parts are electrically and mechanically interchangeable within the specified parameters.

Frequently Asked Questions (FAQ)

Q: Can RMCF0805FT205K replace RMCS0805FT205K directly?

A: Yes. Both parts share identical electrical specifications (205 kOhms ±1%, 0.125W, ±100ppm/°C, -55°C to 155°C) and the same 0805 package. The primary difference is the addition of AEC-Q200 automotive qualification in RMCF0805FT205K. Height variation is 0.026" (0.65mm) versus 0.024" (0.60mm), which is within typical PCB design tolerances.

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

A: AEC-Q200 is an automotive electronics qualification standard. RMCF0805FT205K, CRCW0805205KFKEA, and ERJ-6ENF2053V carry this certification, indicating suitability for automotive applications. The original RMCS0805FT205K does not carry this certification but remains suitable for general industrial and consumer applications.

Q: Does seated height variation affect PCB design?

A: Seated height ranges from 0.020" (CRCW0805205KFKEA) to 0.028" (ERJ-6ENF2053V). Standard PCB design accommodates 0805 components with typical clearances of 0.030" to 0.050", so all options are compatible. Verify specific PCB design rules if clearance is critical.

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

A: Tape & Reel packaging is supplied on continuous reels for automated pick-and-place assembly. Cut Tape & Digi-Reel® (CRCW0805205KFKEA) provides smaller quantities on tape segments. Selection depends on production volume and assembly equipment compatibility.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts are RoHS3 compliant and REACH Unaffected, matching the regulatory status of the original RMCS0805FT205K.

Q: What distinguishes the moisture-resistant feature of RC0805FR-07205KL?

A: RC0805FR-07205KL includes moisture-resistant thick film composition. All parts maintain MSL 1 (Unlimited) rating, indicating no moisture sensitivity concerns. The moisture-resistant feature provides additional protection in high-humidity environments but does not affect standard substitutability.
