Substitute Part Grouping Explanation

Substitute parts for the RNF18FTD82K0 are qualified based on the following criteria:

• Identical resistance value: 82 kOhms
• Identical tolerance: ±1%
• Identical composition: Metal Film
• Identical package type: Axial
• Identical operating temperature range: -55°C to 155°C
• Identical RoHS compliance: ROHS3 Compliant
• Higher power rating: 0.25W (1/4W) — provides increased thermal capability while maintaining all other electrical specifications

The substitute parts RNMF14FAD82K0 and RNMF14FTC82K0 are both qualified upgrades from the RNF series to the RNMF (Mini) series, offering double the power dissipation capacity with no compromise to core electrical parameters.

Parameter Comparison

Engineering Selection Recommendations

Both RNMF14FAD82K0 and RNMF14FTC82K0 are direct substitutes for the RNF18FTD82K0 within the constraints of the provided specifications. Selection between these options depends on application requirements:

RNMF14FAD82K0 maintains the temperature coefficient specification of ±100ppm/°C, matching the original part exactly while providing increased power dissipation at 0.25W.

RNMF14FTC82K0 offers improved temperature stability with ±50ppm/°C temperature coefficient, providing superior performance in temperature-sensitive applications while maintaining all other electrical and compliance requirements.

Both substitute parts are Active status products with ROHS3 compliance and REACH Unaffected status, ensuring regulatory alignment with the original component.

Frequently Asked Questions (FAQ)

Q: Can RNMF14FAD82K0 or RNMF14FTC82K0 be used as direct replacements for RNF18FTD82K0?

A: Yes. Both substitute parts maintain identical resistance, tolerance, composition, package type, and operating temperature range. The increased power rating (0.25W versus 0.125W) represents an upgrade that does not compromise circuit compatibility.

Q: What is the difference between RNMF14FAD82K0 and RNMF14FTC82K0?

A: Both parts are identical except for temperature coefficient. RNMF14FAD82K0 has ±100ppm/°C, while RNMF14FTC82K0 has ±50ppm/°C. For applications requiring tighter temperature stability, RNMF14FTC82K0 is the superior choice.

Q: Does the packaging format change affect circuit board compatibility?

A: The original RNF18FTD82K0 is supplied in Tape & Reel (TR) format, while both substitutes are supplied in Cut Tape (CT) format. This affects procurement and handling but does not impact the component's electrical performance or physical footprint on the circuit board.

Q: Are all three parts RoHS compliant?

A: Yes. RNF18FTD82K0, RNMF14FAD82K0, and RNMF14FTC82K0 are all ROHS3 compliant and REACH Unaffected, meeting current regulatory requirements.

Q: Why would I choose a substitute part with higher power rating?

A: Higher power rating provides thermal margin in applications where the original 0.125W rating operates near its limit. This improves reliability and extends component lifespan without altering electrical characteristics.
