RNF18GTD2K00 Equivalent & Substitute Parts

Part Overview

The RNF18GTD2K00 is a 2 kOhms ±2% metal film through-hole resistor rated at 0.125W (1/8W) in axial package configuration, manufactured by Stackpole Electronics Inc. This component is classified as Active product status with ROHS3 compliance and is suitable for general-purpose electronic applications requiring flame-retardant, safety-rated resistive elements. Substitute parts are identified when equivalent electrical performance, mechanical compatibility, and regulatory compliance can be maintained while addressing specific application requirements such as tolerance precision or power rating upgrades.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RNF18GTD2K00 are qualified based on the following criteria:

Electrical Parameters (Must Match or Exceed):

• Resistance value: 2 kOhms (exact match required)
• Tolerance: ±2% or better (tighter tolerance acceptable)
• Power rating: 0.125W minimum (higher ratings acceptable)
• Composition: Metal Film (required for performance consistency)
• Operating temperature range: -55°C ~ 155°C minimum (same or wider range acceptable)

Mechanical Parameters (Must Match):

• Package type: Axial through-hole configuration
• Physical dimensions: Compatible with 0.071" diameter and 0.130" length specifications

Regulatory & Compliance (Must Match):

• RoHS3 compliance required
• REACH Unaffected status required
• Flame retardant coating and safety features required

Two substitute parts meet these criteria with specific enhancements:

1. RNF18FTD2K00: Identical electrical specifications except tolerance improved to ±1%; same power rating, package, and compliance
2. RNMF14FTC2K00: Identical resistance and tolerance (±1%); power rating upgraded to 0.25W (1/4W); temperature coefficient improved to ±50ppm/°C; same package and compliance

Parameter Comparison

Engineering Selection Recommendations

RNF18FTD2K00 is selected when tolerance precision improvement is required without modifying power dissipation characteristics. This substitute maintains identical power rating and thermal performance while providing ±1% tolerance versus the original ±2%, suitable for applications with tighter resistive value control requirements. Product status is Active with full ROHS3 compliance.

RNMF14FTC2K00 is selected when thermal margin or power dissipation headroom is required. This substitute doubles the power rating to 0.25W (1/4W) and improves temperature coefficient to ±50ppm/°C, providing enhanced stability across the operating temperature range. The RNMF series designation indicates mini-form factor construction with equivalent axial package compatibility. Product status is Active with full ROHS3 compliance.

Both substitutes maintain identical resistance value, operating temperature range, flame-retardant coating, safety features, and regulatory compliance status as the original RNF18GTD2K00.

Frequently Asked Questions (FAQ)

Q: Can RNF18FTD2K00 be used as a direct replacement for RNF18GTD2K00?

A: Yes. RNF18FTD2K00 is electrically and mechanically compatible. The primary difference is improved tolerance (±1% versus ±2%), which provides tighter resistive value control. Power rating, package configuration, operating temperature range, and compliance certifications are identical.

Q: What is the advantage of RNMF14FTC2K00 over the original part?

A: RNMF14FTC2K00 provides two enhancements: doubled power rating (0.25W versus 0.125W) for increased thermal margin, and improved temperature coefficient (±50ppm/°C versus ±100ppm/°C) for better stability across temperature variations. Resistance value and tolerance remain equivalent.

Q: Are the physical dimensions compatible between all three parts?

A: Yes. All three parts use axial through-hole package configuration with compatible dimensions (approximately 0.071" diameter × 0.130" length). They are mechanically interchangeable on standard PCB layouts designed for axial resistors.

Q: Do all substitute parts meet the same compliance requirements?

A: Yes. RNF18FTD2K00 and RNMF14FTC2K00 both maintain ROHS3 compliance, REACH Unaffected status, and flame-retardant coating with safety features identical to RNF18GTD2K00.

Q: Which substitute should be selected for high-temperature applications?

A: Both substitutes maintain the same operating temperature range (-55°C ~ 155°C) as the original part. However, RNMF14FTC2K00 offers superior temperature stability due to its ±50ppm/°C temperature coefficient compared to ±100ppm/°C in both RNF18GTD2K00 and RNF18FTD2K00.

Q: Is packaging format different between Cut Tape (CT) and Tape & Reel (TR) options?

A: Packaging format (Cut Tape versus Tape & Reel) affects supply and handling logistics but does not alter electrical or mechanical component specifications. Component selection should be based on electrical parameters and mechanical compatibility; packaging format is determined by procurement and assembly requirements.
