• Resistance value: 34.8 Ohms (exact match required)
• Tolerance: ±1% (exact match required)
• Power rating: 0.05W / 1/20W (exact match required)
• Package format: 0201 (0603 Metric) (exact match required)
• Composition: Thick Film (exact match required)
• Temperature coefficient: ±200ppm/°C (exact match required)
• Termination count: 2 (exact match required)
• RoHS compliance: ROHS3 Compliant (minimum requirement)
• Moisture sensitivity: MSL 1 (Unlimited) (minimum requirement)

All identified substitute parts meet these core electrical and mechanical specifications, ensuring functional and physical compatibility in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

All three parts—RMCF0201FT34R8, ERJ-1GNF34R8C, and RC0201FR-0734R8L—are Active product status components with ROHS3 compliance and REACH Unaffected designation, meeting current regulatory requirements for electronic component procurement.

The RMCF0201FT34R8 supports an operating temperature range of -55°C to 155°C, providing extended high-temperature performance compared to the substitute parts, which operate to 125°C maximum. Selection between these parts should account for application temperature requirements.

The YAGEO RC0201FR-0734R8L includes moisture-resistant thick film composition as a specified feature, which may provide additional environmental protection in high-humidity applications compared to standard thick film alternatives.

Physical dimensions are identical across all three parts. Height differences (0.28mm maximum for Stackpole versus 0.26mm maximum for Panasonic and YAGEO) are within typical PCB assembly tolerances and do not affect interchangeability in standard surface mount processes.

Frequently Asked Questions (FAQ)

Q: Can ERJ-1GNF34R8C and RC0201FR-0734R8L be used interchangeably with RMCF0201FT34R8?

A: Yes, both substitute parts meet the core electrical specifications: 34.8 Ohm resistance, ±1% tolerance, 0.05W power rating, 0201 package format, thick film composition, and ±200ppm/°C temperature coefficient. Physical dimensions are identical. Substitution is valid for applications operating within the -55°C to 125°C temperature range.

Q: What is the temperature limitation when using substitute parts?

A: The RMCF0201FT34R8 operates to 155°C maximum, while ERJ-1GNF34R8C and RC0201FR-0734R8L are rated to 125°C maximum. For applications requiring operation above 125°C, the Stackpole part is the appropriate selection.

Q: Are all parts RoHS compliant?

A: Yes, all three parts are ROHS3 Compliant and REACH Unaffected, meeting current environmental and regulatory standards for electronic component procurement.

Q: Does the moisture-resistant feature of the YAGEO part affect compatibility?

A: No, the moisture-resistant thick film composition of RC0201FR-0734R8L is a material enhancement that does not affect electrical or mechanical compatibility. It provides additional environmental protection without changing the core electrical parameters.

Q: Are there physical differences that affect PCB assembly?

A: All parts use identical 0201 package format and dimensions (0.024" L x 0.012" W). Maximum seated height varies slightly: Stackpole 0.28mm versus Panasonic and YAGEO 0.26mm. These differences are within standard PCB assembly tolerances and do not affect pick-and-place or reflow processes.

Q: What is the MSL rating for these parts?

A: All three parts have Moisture Sensitivity Level 1 (Unlimited), indicating no moisture sensitivity restrictions for storage, handling, or assembly processes.
