Substitute Part Grouping Explanation

The RLR07C1504FSB14 qualifies as a parametric equivalent to the RLR07C1504FSBSL based on strict electrical and mechanical parameter matching. Substitution is valid when the following criteria are met:

• Resistance value: 1.5 MOhms (identical)
• Tolerance: ±1% (identical)
• Power rating: 0.25W, 1/4W (identical)
• Composition: Metal Film (identical)
• Temperature coefficient: ±100ppm/°C (identical)
• Operating temperature range: -65°C to 150°C (identical)
• Package type: Axial (identical)
• Physical dimensions: 0.090" Dia x 0.250" L (identical)
• Military series compliance: MIL-PRF-39017/01, RLR07 (identical)
• Features: Military, Moisture Resistant, Weldable (identical)
• Failure rate: S (0.001%) (identical)

Both parts maintain identical specifications across all electrical and mechanical parameters, confirming direct substitution capability within the RLR07 military resistor series.

Parameter Comparison

Engineering Selection Recommendations

Both the RLR07C1504FSBSL and RLR07C1504FSB14 are active production parts manufactured by Vishay Dale within the military-grade RLR07 series. Selection between these parts should be based on inventory availability and supply chain requirements. The RLR07C1504FSB14 currently maintains higher inventory levels at 964 units compared to 652 units for the RLR07C1504FSBSL. Both parts carry identical compliance certifications including MIL-PRF-39017/01 military specification compliance, EAR99 export classification, and REACH affected status. Neither part is RoHS compliant, which is consistent with military-grade resistor specifications. Component selection should account for procurement lead times and project-specific supply chain constraints.

Frequently Asked Questions (FAQ)

Q: Can RLR07C1504FSB14 be used as a direct replacement for RLR07C1504FSBSL?

A: Yes. Both parts are parametric equivalents with identical electrical specifications (1.5 MOhms ±1%), power rating (0.25W), temperature coefficient (±100ppm/°C), operating temperature range (-65°C to 150°C), and physical dimensions (0.090" Dia x 0.250" L). Both comply with MIL-PRF-39017/01 military specifications and feature identical moisture-resistant, weldable metal film construction.

Q: Are there any differences in military compliance between these parts?

A: No. Both parts are manufactured to the same MIL-PRF-39017/01 specification within the RLR07 military resistor series. Both maintain identical failure rate classifications (S, 0.001%) and feature sets.

Q: What is the significance of the different part number suffixes?

A: The part numbers differ only in their suffix designations (FSBSL versus FSB14). Both suffixes represent valid manufacturing variants within the RLR07 series that maintain identical electrical and mechanical parameters. The difference does not affect functional performance or compatibility.

Q: Are there any RoHS or environmental compliance considerations?

A: Both parts are RoHS non-compliant and REACH affected. This classification is standard for military-grade resistors and does not indicate a deficiency. Applications requiring RoHS compliance would require alternative component selection outside the military RLR07 series.

Q: How should inventory levels influence component selection?

A: The RLR07C1504FSB14 maintains higher current inventory (964 units) compared to the RLR07C1504FSBSL (652 units). For applications with extended production runs or supply chain risk mitigation requirements, the higher inventory availability of the FSB14 variant may provide procurement advantages.
