Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RLR05C1001FSRE6 is determined by the following critical parameters:

• Resistance value: 1 kOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Power rating: 0.125W / 1/8W (exact match required)
• Composition: Metal Film (exact match required)
• Package: Axial through-hole (exact match required)
• Temperature coefficient: ±100ppm/°C (exact match required)
• Number of terminations: 2 (exact match required)

The RNF18FTD1K00 from Stackpole Electronics Inc qualifies as a substitute part because it matches all critical electrical and mechanical parameters. Both components are metal film axial resistors with identical resistance, tolerance, power rating, and temperature coefficient specifications. Physical dimensions vary slightly but remain compatible with standard axial component footprints and handling equipment.

Parameter Comparison

Engineering Selection Recommendations

The RNF18FTD1K00 serves as a functional equivalent to the RLR05C1001FSRE6 based on matching electrical specifications and axial package compatibility. Both components deliver identical resistance, tolerance, power dissipation, and temperature stability characteristics required for circuit performance.

Key compliance differences exist between the two parts. The RLR05C1001FSRE6 is RoHS non-compliant and carries REACH Affected status, reflecting its military-grade classification. The RNF18FTD1K00 is ROHS3 Compliant and REACH Unaffected, making it suitable for applications with environmental compliance requirements.

Operating temperature ranges differ slightly. The RLR05C1001FSRE6 operates from -65°C to 150°C, while the RNF18FTD1K00 operates from -55°C to 155°C. Selection between these parts depends on whether the application requires the extended low-temperature performance of the military-grade component or can accept the commercial-grade temperature envelope.

Physical dimensions show minor variations. The RLR05C1001FSRE6 measures 0.066" diameter by 0.150" length, while the RNF18FTD1K00 measures 0.071" diameter by 0.130" length. Both dimensions remain within standard axial component handling and PCB mounting tolerances.

Frequently Asked Questions (FAQ)

Q: Can the RNF18FTD1K00 replace the RLR05C1001FSRE6 in all applications?

A: The RNF18FTD1K00 matches all critical electrical parameters (resistance, tolerance, power rating, temperature coefficient) and package type. Substitution is valid for applications where the operating temperature range of -55°C to 155°C is acceptable and RoHS3 compliance is not a constraint. Military applications requiring MIL-PRF-39017/05 certification or extended low-temperature operation below -55°C require the original RLR05C1001FSRE6.

Q: What are the physical dimension differences, and do they affect PCB layout?

A: The RLR05C1001FSRE6 is 0.066" diameter by 0.150" length; the RNF18FTD1K00 is 0.071" diameter by 0.130" length. Both components fit standard axial resistor footprints and spacing. The slightly larger diameter and shorter length of the RNF18FTD1K00 do not create PCB layout conflicts for typical through-hole designs.

Q: What is the difference in RoHS compliance between these parts?

A: The RLR05C1001FSRE6 is RoHS non-compliant, indicating it may contain restricted substances permitted under military exemptions. The RNF18FTD1K00 is ROHS3 Compliant, meeting current environmental standards for commercial and industrial applications. Selection depends on regulatory requirements for the end application.

Q: Are both parts available in the same packaging format?

A: Yes. Both the RLR05C1001FSRE6 and RNF18FTD1K00 are supplied in Cut Tape (CT) packaging, ensuring compatibility with standard component handling and placement equipment.

Q: How do the temperature coefficients compare?

A: Both parts have identical temperature coefficients of ±100ppm/°C, ensuring equivalent frequency stability and resistance drift characteristics across temperature variations.
