Key Parameters

Substitute Part Grouping Explanation

Substitution within the RLR07 series is determined by matching the following critical parameters:

• Resistance value: 2 kOhms
• Tolerance: ±1%
• Power rating: 0.25W (1/4W)
• Composition: Metal Film
• Package: Axial
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -65°C to 150°C
• Physical dimensions: 0.090" Dia x 0.250" L
• Military series compliance: MIL-PRF-39017/01

The RLR07C2001FSB14 meets all these criteria and is classified as a direct substitute. The primary distinction between the main part and substitute is the failure rate specification, which does not affect electrical or mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both RLR07C2001FMB14 and RLR07C2001FSB14 are active production parts from Vishay Dale within the military-grade RLR07 series. Selection between these parts should be based on failure rate requirements for the application. The RLR07C2001FSB14 offers a lower failure rate specification (0.001% versus 1%), making it suitable for high-reliability applications where extended operational life and reduced failure probability are critical. Both parts maintain identical electrical characteristics, physical dimensions, and environmental specifications. Compliance status is equivalent across both parts, with identical RoHS non-compliance and REACH-affected designations.
