RMC1/8K41R2FTP Equivalent & Substitute Parts

Part Overview

The RMC1/8K41R2FTP is a 41.2 Ohm ±1% 0.25W thick film chip resistor manufactured by Kamaya Inc. in 1206 (3216 Metric) surface mount package format. This component is classified as Active product status with unlimited moisture sensitivity rating (MSL 1). Substitute parts are necessary when primary inventory is unavailable, when design requirements mandate specific manufacturer certifications such as AEC-Q200 automotive qualification, or when alternative sourcing improves supply chain resilience for production environments.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for RMC1/8K41R2FTP is determined by strict equivalence across the following parameters: resistance value (41.2 Ohms), tolerance (±1%), power rating (0.25W), package format (1206), composition (thick film), temperature coefficient (±100ppm/°C), operating temperature range (-55°C ~ 155°C), and termination count (2). All substitute parts listed meet these core electrical and mechanical specifications. Substitutes are grouped by product status and compliance certifications: Active status parts with standard thick film construction, Active status parts with automotive AEC-Q200 qualification, and Discontinued parts with full RoHS3 compliance. Dimensional variations within supplier device package specifications (1206) are acceptable for PCB assembly compatibility.

Parameter Comparison

Engineering Selection Recommendations

For Standard Applications (Non-Automotive): RC1206FR-0741R2L (YAGEO) is the primary substitute. This part maintains Active product status, includes moisture-resistant thick film construction, and carries full RoHS3 compliance. Inventory availability is 57,546 pieces.

For Automotive Applications (AEC-Q200 Required): RMCF1206FT41R2 (Stackpole Electronics Inc) is the preferred substitute. This part is Active status, carries AEC-Q200 automotive qualification, and maintains RoHS3 compliance. Inventory availability is 5,375 pieces. ERJ-8ENF41R2V (Panasonic Electronic Components) is an alternative automotive-qualified substitute with AEC-Q200 rating and 51,218 pieces in stock; however, this part is marked "Not For New Designs" and should be used only for legacy system maintenance or existing design continuity.

For Discontinued/Legacy Sourcing: MCR18ERTF41R2 (Rohm Semiconductor) is available with 9,365 pieces in stock but is Discontinued at DiGi Electronics. This part is suitable only for repair, rework, or replacement in existing systems where supply chain continuity is critical.

Frequently Asked Questions (FAQ)

Q: Can ERJ-8ENF41R2V replace RMC1/8K41R2FTP in new designs? A: ERJ-8ENF41R2V meets all electrical and mechanical specifications for direct substitution. However, this part is marked "Not For New Designs" by the manufacturer. Use only for legacy system maintenance or existing design continuity. For new designs, select RC1206FR-0741R2L or RMCF1206FT41R2.

Q: What is the difference between standard and automotive-qualified substitutes? A: Automotive-qualified substitutes (ERJ-8ENF41R2V and RMCF1206FT41R2) carry AEC-Q200 certification, indicating compliance with automotive reliability and qualification standards. Standard substitutes (RC1206FR-0741R2L) do not carry this certification. Select automotive-qualified parts only when AEC-Q200 compliance is a design requirement.

Q: Are dimensional variations between substitute parts significant? A: All substitute parts use the 1206 (3216 Metric) package format. Minor dimensional variations (length 0.120" to 0.126", height 0.025" to 0.028") are within supplier device package tolerances and do not affect PCB assembly compatibility or electrical performance.

Q: Is RoHS3 compliance required for all substitutes? A: RoHS3 compliance is provided by RC1206FR-0741R2L, RMCF1206FT41R2, and MCR18ERTF41R2. The main part (RMC1/8K41R2FTP) does not specify RoHS status. Verify RoHS compliance requirements with your design specifications before final part selection.

Q: Can MCR18ERTF41R2 be used despite being discontinued? A: MCR18ERTF41R2 is electrically and mechanically equivalent and currently has 9,365 pieces in stock. Use this part only when other Active status substitutes are unavailable and supply chain continuity is critical. Plan for long-term sourcing alternatives.

Q: What is the significance of MSL 1 (Unlimited) rating? A: MSL 1 (Unlimited) indicates the component has unlimited shelf life and requires no special moisture control during storage or handling. All listed substitutes carry this same MSL rating, ensuring equivalent moisture sensitivity performance.
