RMCS0805FT348K Equivalent & Substitute Parts

Part Overview

The RMCS0805FT348K is a 348 kOhms ±1% 0.125W thick film chip resistor in 0805 (2012 Metric) package manufactured by Stackpole Electronics Inc. This component is classified as Active product status with anti-sulfur composition and unlimited moisture sensitivity rating. Equivalent parts are necessary when the primary part experiences supply constraints, when design requirements mandate specific manufacturer certifications such as AEC-Q200 automotive qualification, or when application-specific features such as high voltage capability or moisture resistance are required.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RMCS0805FT348K is determined by strict equivalence across the following parameters: resistance value (348 kOhms), tolerance (±1%), power rating (0.125W), package type (0805), composition (thick film), temperature coefficient (±100ppm/°C), operating temperature range (-55°C to 155°C), and compliance certifications (ROHS3, REACH Unaffected, EAR99). All identified substitute parts meet these core electrical and mechanical requirements. Substitute parts are grouped by manufacturer and may include additional features such as automotive AEC-Q200 qualification, high voltage capability, or moisture resistance, which represent enhancements to the base specification rather than deviations from it.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts maintain full electrical and mechanical compatibility with the RMCS0805FT348K across core specifications. Selection between equivalents should be based on application-specific requirements and compliance mandates:

CRCW0805348KFKEA (Vishay Dale) and ERJ-6ENF3483V (Panasonic Electronic Components) are qualified to AEC-Q200 automotive standard and are suitable for automotive and high-reliability applications requiring formal qualification documentation.

KTR10EZPF3483 (Rohm Semiconductor) combines AEC-Q200 automotive qualification with high voltage capability, appropriate for applications requiring enhanced voltage performance within the automotive qualification framework.

RC0805FR-07348KL (YAGEO) features moisture-resistant composition and is suitable for applications in humid or moisture-prone environments where enhanced environmental protection is specified.

All parts maintain ROHS3 compliance, REACH unaffected status, and EAR99 export classification consistent with the primary part.

Frequently Asked Questions (FAQ)

Q: Can CRCW0805348KFKEA replace RMCS0805FT348K in non-automotive applications? A: Yes. CRCW0805348KFKEA meets all electrical and mechanical specifications of RMCS0805FT348K. AEC-Q200 qualification is an additional feature that does not restrict use in non-automotive circuits.

Q: What is the significance of the height difference between substitute parts? A: Height variations (0.50mm to 0.70mm maximum seated height) are within standard 0805 package tolerance. These differences do not affect electrical performance and are compatible with standard PCB assembly processes. Verify clearance requirements for specific board designs if height-constrained applications are present.

Q: Is KTR10EZPF3483 suitable for standard applications, or is high voltage capability required? A: KTR10EZPF3483 is suitable for all applications compatible with RMCS0805FT348K. High voltage capability represents an enhancement and is not a requirement for standard operation.

Q: Does moisture resistance in RC0805FR-07348KL provide additional protection in all environments? A: Moisture resistance is beneficial in humid or moisture-prone environments. For standard indoor applications with controlled humidity, this feature provides no functional advantage over the primary part.

Q: Are all substitute parts available in Tape & Reel packaging? A: Yes. All identified substitute parts are supplied in Tape & Reel (TR) packaging consistent with the primary part.
