RN60D2001FRSL Equivalent & Substitute Parts

Part Overview

The RN60D2001FRSL is a 2 kOhms ±1% metal film axial resistor rated at 0.25W (1/4W) manufactured by Vishay Dale. This component is part of the military-grade RN60 series, featuring flame retardant coating, moisture resistance, and safety certification per MIL-R-10509/1. The part is currently active in production with 817 units in stock.

Substitute parts are necessary when the original packaging format (Tape & Reel) is unavailable, when tighter tolerance specifications are required for precision applications, or when alternative temperature coefficient performance is needed for specific circuit requirements.

Substitute Part Grouping Explanation

Substitution eligibility for the RN60D2001FRSL is determined by the following criteria:

Electrical Parameters (Must Match):

Resistance value: 2 kOhms
Power rating: 0.25W (1/4W)
Composition: Metal Film
Operating temperature range: -65°C to 175°C
Series compliance: RN60 military series, MIL-R-10509/1

Allowable Variations:

Tolerance: ±1% (main part) can be substituted with ±0.1% (tighter tolerance acceptable)
Temperature coefficient: ±100ppm/°C (main part) can be substituted with ±50ppm/°C or ±25ppm/°C (lower coefficients acceptable)
Packaging format: Tape & Reel (TR), Bulk, or Cut Tape (CT) are interchangeable for circuit functionality

Non-Substitutable Parameters:

Resistance value must remain 2 kOhms
Power rating must remain 0.25W
Physical dimensions and axial package type are fixed
Military series designation and flame retardant coating are required

Engineering Selection Recommendations

Direct Substitutes (Identical Electrical Performance): RN60D2001FB14 and RN60D2001FRE6 are direct functional equivalents with identical resistance, tolerance, power rating, and temperature coefficient. Selection between these and the main part depends solely on packaging availability and procurement requirements. RN60D2001FRE6 offers the highest inventory level (10,770 units).

Upgraded Substitutes (Enhanced Performance): RN60C2001FB14 and RN60C2001FRE6 provide improved temperature coefficient stability (±50ppm/°C versus ±100ppm/°C) while maintaining ±1% tolerance. These are suitable for applications requiring better thermal stability without sacrificing tolerance specifications.

RN60C2001BB14 and RN60E2001BB14 offer the highest precision with ±0.1% tolerance and superior temperature coefficients (±50ppm/°C and ±25ppm/°C respectively). RN60E2001BB14 represents the highest performance option with ±25ppm/°C temperature coefficient. These upgrades are appropriate for precision measurement circuits and applications with stringent accuracy requirements.

All substitute parts maintain compliance with MIL-R-10509/1 military specifications, flame retardant coating, moisture resistance, and the -65°C to 175°C operating temperature range of the original part.

Frequently Asked Questions (FAQ)

Q: Can RN60D2001FB14 (Bulk packaging) be used in place of RN60D2001FRSL (Tape & Reel)? A: Yes. Both parts have identical electrical specifications (2 kOhms, ±1%, 0.25W, ±100ppm/°C). The packaging difference (Bulk versus Tape & Reel) affects only procurement and assembly handling, not circuit performance.

Q: What is the difference between RN60D2001FRSL and RN60C2001FB14? A: The primary difference is temperature coefficient: RN60D2001FRSL has ±100ppm/°C while RN60C2001FB14 has ±50ppm/°C. Both maintain 2 kOhms resistance and ±1% tolerance. RN60C2001FB14 provides better thermal stability for temperature-sensitive applications.

Q: When should I use RN60E2001BB14 instead of the original RN60D2001FRSL? A: RN60E2001BB14 is appropriate when circuit design requires tighter tolerance (±0.1% versus ±1%) and superior temperature coefficient stability (±25ppm/°C versus ±100ppm/°C). This upgrade is necessary for precision analog circuits, reference networks, or applications with wide operating temperature ranges where drift must be minimized.

Q: Are all substitute parts RoHS non-compliant like the original? A: Yes. All listed substitute parts maintain RoHS non-compliant status consistent with the original RN60D2001FRSL, as they are military-grade components manufactured to MIL-R-10509/1 specifications.

Q: Can I mix different substitute parts in the same assembly? A: Yes, provided the circuit design tolerates the parameter variations. Direct equivalents (RN60D2001FB14, RN60D2001FRE6) are fully interchangeable. Upgraded parts with tighter tolerances or lower temperature coefficients can be mixed with the original specification without degradation, though this may introduce unnecessary cost.

Q: Which substitute has the best availability? A: RN60D2001FRE6 (Cut Tape packaging) has the highest inventory at 10,770 units, followed by RN60C2001FRE6 at 2,058 units.
