Key Parameters

Substitute Part Grouping Explanation

The RNMF14FTC10R0 qualifies as a substitute for the RNF18FTC10R0 based on the following matching parameters:

• Resistance value: 10 Ohms (identical)
• Tolerance: ±1% (identical)
• Composition: Metal Film (identical)
• Temperature Coefficient: ±50ppm/°C (identical)
• Operating Temperature Range: -55°C ~ 155°C (identical)
• Package Type: Axial (identical)
• Features: Flame Retardant Coating, Safety (identical)
• RoHS Status: ROHS3 Compliant (identical)
• Manufacturer: Stackpole Electronics Inc (same manufacturer)

The primary difference is the power rating: the substitute part is rated at 0.25W (1/4W) versus the original 0.125W (1/8W). This represents an upgrade in power dissipation capability, making the substitute suitable for applications requiring equal or lower power handling than the original specification.

Parameter Comparison

Engineering Selection Recommendations

The RNMF14FTC10R0 substitute part maintains all critical electrical parameters including resistance value, tolerance, temperature coefficient, and operating temperature range. Both components are manufactured by Stackpole Electronics Inc and carry identical ROHS3 compliance and safety certifications. The substitute provides increased power dissipation capability at 0.25W compared to the original 0.125W rating, which is compatible with applications designed for the lower power specification. Physical dimensions are nearly identical with negligible differences in diameter and length, ensuring mechanical compatibility in standard axial component footprints. Product status is Active for both parts, confirming ongoing availability and support.

Frequently Asked Questions (FAQ)

Q: Can RNMF14FTC10R0 directly replace RNF18FTC10R0 in all applications?

A: Yes, the RNMF14FTC10R0 is electrically and mechanically compatible as a substitute. The higher power rating (0.25W vs 0.125W) provides additional thermal margin without affecting circuit performance for applications designed around the original 0.125W specification.

Q: Are the physical dimensions compatible for PCB mounting?

A: Both components use axial package configuration with nearly identical dimensions (0.071" vs 0.070" diameter, both 0.130" length). Standard axial component footprints accommodate both parts without modification.

Q: Do both parts meet the same compliance standards?

A: Yes, both RNF18FTC10R0 and RNMF14FTC10R0 are ROHS3 compliant with identical flame retardant coating and safety features. REACH status is REACH Unaffected for both parts.

Q: What is the difference between the RNF and RNMF series?

A: The RNF18FTC10R0 belongs to the RNF series, while the RNMF14FTC10R0 belongs to the RNMF (Mini) series. Both are metal film axial resistors from Stackpole Electronics Inc with identical electrical specifications for this 10 Ohm ±1% application.

Q: Is the temperature coefficient the same for both parts?

A: Yes, both components have a temperature coefficient of ±50ppm/°C and operate across the identical temperature range of -55°C to 155°C.
