Substitute Part Grouping Explanation

Substitute parts for the RMCF2010FT34R8 are qualified based on strict equivalence across all critical electrical and mechanical parameters. The substitution criteria are:

• Resistance value: 34.8 Ohms
• Tolerance: ±1%
• Power rating: 0.75W
• Package: 2010 (5025 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C
• Automotive qualification: AEC-Q200
• RoHS compliance: ROHS3 Compliant
• Physical dimensions: 0.197" L x 0.098" W (5.00mm x 2.50mm), Height 0.028" (0.70mm) maximum

All identified substitutes meet these parameters identically, ensuring direct functional and mechanical interchangeability in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

The RMCF2010FT34R8 from Stackpole Electronics Inc is the primary component with active production status. Both substitute parts provide electrical and mechanical equivalence:

CRCW201034R8FKEF (Vishay Dale) is actively produced and represents a direct equivalent suitable for new designs and production applications requiring alternative sourcing.

ERJ-12SF34R8U (Panasonic Electronic Components) maintains full parameter equivalence but carries a "Not For New Designs" status. This part is suitable for legacy system maintenance, repair, and replacement applications where existing inventory or established supply chains are in use. For new design implementations, CRCW201034R8FKEF or RMCF2010FT34R8 are preferred.

All three parts satisfy automotive AEC-Q200 qualification and ROHS3 compliance requirements.

Frequently Asked Questions (FAQ)

Q: Can CRCW201034R8FKEF be used as a direct replacement for RMCF2010FT34R8?

A: Yes. Both parts are electrically and mechanically identical across all specified parameters: 34.8 Ohm resistance, ±1% tolerance, 0.75W power rating, 2010 package, ±100ppm/°C temperature coefficient, -55°C to 155°C operating range, AEC-Q200 automotive rating, and ROHS3 compliance. Pin-to-pin and footprint compatibility is assured.

Q: Why is ERJ-12SF34R8U marked "Not For New Designs"?

A: The "Not For New Designs" status indicates that Panasonic has discontinued active development and promotion of this part line. However, the part remains functionally equivalent and is available from existing inventory. It is appropriate for maintenance, repair, and legacy system applications but should not be selected for new product development where RMCF2010FT34R8 or CRCW201034R8FKEF are available.

Q: Are there any package or footprint differences between these three parts?

A: No. All three parts use the identical 2010 (5025 Metric) package with matching physical dimensions: 0.197" L x 0.098" W (5.00mm x 2.50mm) and maximum seated height of 0.028" (0.70mm). PCB footprints and land patterns are interchangeable.

Q: Do all substitute parts meet automotive qualification requirements?

A: Yes. RMCF2010FT34R8, CRCW201034R8FKEF, and ERJ-12SF34R8U all carry AEC-Q200 automotive qualification and are ROHS3 compliant, meeting automotive industry standards for reliability and environmental compliance.

Q: What is the moisture sensitivity level for these parts?

A: All three parts have MSL rating of 1 (Unlimited), indicating no moisture sensitivity restrictions. Standard handling and storage procedures apply without special moisture control requirements.
