Substitute Part Grouping Explanation

Substitution eligibility for the RLR05C1822FSBSL is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part RLR05C1822FSB14 qualifies as a direct parametric equivalent based on the following criteria:

• Identical resistance value: 18.2 kOhms
• Matching tolerance specification: ±1%
• Equivalent power rating: 0.125W (1/8W)
• Same composition: Metal Film
• Identical temperature coefficient: ±100ppm/°C
• Matching operating temperature range: -65°C to 150°C
• Same package configuration: Axial
• Identical physical dimensions: 0.066" Dia × 0.150" L (1.68mm × 3.81mm)
• Same military series classification: MIL-PRF-39017/05, RLR05
• Matching features: Military Grade, Moisture Resistant, Weldable
• Equivalent failure rate: S (0.001%)

Parameter Comparison

Engineering Selection Recommendations

Both RLR05C1822FSBSL and RLR05C1822FSB14 maintain active product status with full availability. Selection between these parts should be based on procurement lead times and inventory levels. The RLR05C1822FSB14 currently maintains higher inventory (979 units versus 883 units), which may provide supply chain advantages for high-volume applications. Both parts comply with identical military specifications (MIL-PRF-39017/05) and carry equivalent REACH and ECCN classifications (REACH Affected, EAR99). Neither part achieves RoHS compliance, which is consistent with military-grade metal film resistor specifications. Both parts are suitable for direct substitution in applications requiring military-grade, moisture-resistant, weldable resistors with identical electrical performance across the full operating temperature range.

Frequently Asked Questions (FAQ)

Q: Can RLR05C1822FSB14 be used as a direct replacement for RLR05C1822FSBSL?

A: Yes. Both parts are parametrically identical across all electrical specifications (18.2 kOhms ±1%, 0.125W, ±100ppm/°C, -65°C to 150°C), composition (metal film), and mechanical configuration (axial package, 0.066" Dia × 0.150" L). Both comply with MIL-PRF-39017/05 and carry identical military-grade features.

Q: Are there any differences in package or physical dimensions?

A: No. Both parts share identical axial package configuration and physical dimensions of 0.066" Dia × 0.150" L (1.68mm × 3.81mm), ensuring mechanical compatibility in PCB layouts and through-hole applications.

Q: What is the significance of the different part number suffixes (FSBSL versus FSB14)?

A: The suffix variation reflects different procurement or packaging batches from Vishay Dale within the same RLR05 military series. The electrical and mechanical specifications remain identical, and both parts meet MIL-PRF-39017/05 requirements.

Q: Do both parts have the same compliance status?

A: Yes. Both parts carry identical REACH (REACH Affected) and ECCN (EAR99) classifications. Neither achieves RoHS compliance, which is standard for military-grade metal film resistors per MIL-PRF-39017/05.

Q: Which part should be selected for new designs?

A: Either part is suitable for new designs. Selection may be based on current inventory availability (RLR05C1822FSB14 currently has 979 units in stock) or specific procurement agreements with Vishay Dale.
