RMCS0805FT44K2 Equivalent & Substitute Parts

Part Overview

The RMCS0805FT44K2 is a 44.2 kOhms ±1% 0.125W thick film chip resistor in 0805 (2012 Metric) package manufactured by Stackpole Electronics Inc. This component is classified as Active status and is RoHS3 compliant. Equivalent and substitute parts are necessary when the primary part experiences supply constraints, extended lead times, or when design requirements mandate specific manufacturer certifications such as automotive AEC-Q200 qualification or enhanced moisture resistance features.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RMCS0805FT44K2 is determined by strict equivalence across the following parameters: resistance value (44.2 kOhms), tolerance (±1%), power rating (0.125W), package type (0805), composition (thick film), temperature coefficient (±100ppm/°C), operating temperature range (-55°C ~ 155°C), and compliance certifications (RoHS3, REACH Unaffected). All listed substitute parts meet these core electrical and mechanical requirements. Variations in packaging format (Tape & Reel vs. Cut Tape), special features (Automotive AEC-Q200, Moisture Resistant, Anti-Sulfur), and minor dimensional differences in seated height do not affect functional interchangeability within standard circuit applications.

Parameter Comparison

Engineering Selection Recommendations

All four parts are Active status components with full RoHS3 compliance and REACH Unaffected designation. Selection between the RMCS0805FT44K2 and its substitutes should be based on application-specific requirements:

CRCW080544K2FKEA (Vishay Dale) and ERJ-6ENF4422V (Panasonic) are qualified to Automotive AEC-Q200 standard and are suitable for automotive and mission-critical applications requiring enhanced reliability screening and qualification documentation.

RC0805FR-0744K2L (YAGEO) features moisture-resistant construction and is appropriate for applications in high-humidity or corrosive environments.

RMCS0805FT44K2 (Stackpole) features anti-sulfur construction, providing protection against sulfur-containing contaminants in industrial environments.

All parts maintain identical electrical performance across the specified operating temperature range and are mechanically compatible with standard 0805 PCB footprints.

Frequently Asked Questions (FAQ)

Q: Can CRCW080544K2FKEA replace RMCS0805FT44K2 in non-automotive applications? A: Yes. The CRCW080544K2FKEA meets all core electrical and mechanical parameters of the RMCS0805FT44K2. The AEC-Q200 automotive qualification is an additional feature that does not restrict use in standard industrial or consumer applications.

Q: What is the difference between Anti-Sulfur and Moisture Resistant features? A: Anti-Sulfur protection (RMCS0805FT44K2) guards against sulfur-containing atmospheric contaminants and corrosive gases. Moisture Resistant construction (RC0805FR-0744K2L) provides enhanced protection against humidity and moisture ingress. These are distinct environmental protection mechanisms suited to different application environments.

Q: Are all substitute parts compatible with the same PCB footprint? A: Yes. All parts use the 0805 (2012 Metric) package with identical land pattern dimensions (0.079" L x 0.049" W / 2.00mm x 1.25mm). Minor variations in seated height (0.020" to 0.028") do not affect PCB assembly compatibility.

Q: Which substitute part has the lowest seated height? A: CRCW080544K2FKEA (Vishay Dale) has a maximum seated height of 0.020" (0.50mm), compared to 0.024" (0.60mm) for RMCS0805FT44K2 and RC0805FR-0744K2L, and 0.028" (0.70mm) for ERJ-6ENF4422V.

Q: Do all parts have the same packaging options? A: RMCS0805FT44K2, CRCW080544K2FKEA, and RC0805FR-0744K2L are supplied in Tape & Reel (TR) format. ERJ-6ENF4422V is supplied in Cut Tape (CT) & Digi-Reel® format. Both formats are standard for automated assembly processes.

Q: Are all parts RoHS3 compliant? A: Yes. All four parts are RoHS3 compliant and REACH Unaffected, meeting current environmental and regulatory requirements for electronic component manufacturing and distribution.
