RMCF2010FT348K Equivalent & Substitute Parts

Part Overview

The RMCF2010FT348K is a 348 kOhms ±1% 0.75W chip resistor in 2010 (5025 Metric) package manufactured by Stackpole Electronics Inc. This thick film resistor meets automotive AEC-Q200 qualification and operates across -55°C to 155°C. The part is currently in active production status with ROHS3 compliance.

Substitute parts are necessary when the primary manufacturer part becomes unavailable, when supply chain constraints require alternative sourcing, or when design flexibility permits equivalent components that meet identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RMCF2010FT348K is determined by strict equivalence across the following parameters:

• Resistance value: 348 kOhms
• Tolerance: ±1%
• Power rating: 0.75W
• Package: 2010 (5025 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C to 155°C
• Automotive qualification: AEC-Q200
• Termination count: 2
• Moisture sensitivity: MSL 1

The ERJ-12SF3483U from Panasonic Electronic Components meets all electrical and mechanical parameters required for direct substitution. This part maintains identical resistance, tolerance, power rating, package dimensions, and thermal characteristics. Both parts are qualified to AEC-Q200 automotive standards and operate within the same temperature envelope.

Parameter Comparison

Engineering Selection Recommendations

The RMCF2010FT348K is the preferred selection for new designs due to its active production status and ROHS3 compliance. This part is suitable for automotive applications requiring AEC-Q200 qualification and operates reliably across the full -55°C to 155°C temperature range.

The ERJ-12SF3483U provides electrical and mechanical equivalence but carries a "Not For New Designs" status and does not meet ROHS3 compliance. This part is suitable only for legacy system support, repair applications, or situations where existing inventory must be maintained. The RoHS non-compliance status restricts its use in applications subject to RoHS3 regulatory requirements.

Frequently Asked Questions (FAQ)

Q: Can ERJ-12SF3483U be used as a direct replacement for RMCF2010FT348K in new designs?

A: No. While the ERJ-12SF3483U meets all electrical and mechanical specifications, its "Not For New Designs" status and RoHS non-compliance make it unsuitable for new product development. The RMCF2010FT348K is the correct choice for new designs.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both parts use the 2010 (5025 Metric) package with identical dimensions: 0.197" L x 0.098" W (5.00mm x 2.50mm) and maximum seated height of 0.028" (0.70mm). PCB footprints are interchangeable.

Q: Do both parts meet automotive AEC-Q200 qualification?

A: Yes. Both the RMCF2010FT348K and ERJ-12SF3483U are qualified to AEC-Q200 automotive standards and operate across -55°C to 155°C with ±100ppm/°C temperature coefficient.

Q: What is the significance of the RoHS compliance difference?

A: The RMCF2010FT348K is ROHS3 compliant, meeting current regulatory requirements for products sold in regions with RoHS3 mandates. The ERJ-12SF3483U is RoHS non-compliant and cannot be used in applications subject to these regulations.

Q: Are there any differences in tolerance or power rating?

A: No. Both parts are specified at ±1% tolerance and 0.75W power rating with identical temperature coefficients and operating ranges.
