RLR05C3322FSRSL19 Equivalent & Substitute Parts

Part Overview

The RLR05C3322FSRSL19 is a 33.2 kOhms ±1% metal film through-hole resistor rated at 0.125W (1/8W) in axial package configuration. Manufactured by Vishay Dale under the military-grade RLR05 series per MIL-PRF-39017/05 specification, this component is designed for applications requiring moisture resistance and weldability in military and aerospace environments. The part maintains active product status with 807 units currently in stock. Substitute parts may be required due to inventory constraints, procurement lead times, or specific packaging preferences while maintaining identical electrical and mechanical specifications.

Engineering Selection Recommendations

Both RLR05C3322FSRSL19 and RLR05C3322FSB14 maintain active product status with full military compliance under MIL-PRF-39017/05 specification. Selection between these parts should be based on procurement availability and inventory levels. The RLR05C3322FSB14 currently maintains higher inventory (947 units versus 807 units), which may provide advantages for high-volume production requirements or extended lead-time mitigation. Both parts carry identical RoHS non-compliance status and REACH affected classification, with matching ECCN (EAR99) and HTSUS (8533.21.0090) designations. No technical differentiation exists between these components; substitution is direct and interchangeable for all circuit applications.

Frequently Asked Questions (FAQ)

Q: Can RLR05C3322FSB14 be used as a direct replacement for RLR05C3322FSRSL19?

A: Yes. Both parts are electrically and mechanically identical across all specified parameters, including resistance value, tolerance, power rating, temperature coefficient, operating temperature range, package configuration, and physical dimensions. Direct substitution is valid for all applications.

Q: Are there any differences in military compliance or certifications?

A: No. Both parts comply with MIL-PRF-39017/05 specification and carry identical military series classification (RLR05). Failure rate, moisture resistance, and weldability specifications are equivalent.

Q: What is the significance of the different part number suffixes (FSRSL19 versus FSB14)?

A: The suffix variations indicate different packaging or distribution configurations from Vishay Dale. The electrical and mechanical specifications remain identical. The suffix does not affect circuit performance or compatibility.

Q: Are there any PCB layout or assembly considerations when substituting between these parts?

A: No. Both parts share identical axial package configuration and physical dimensions (0.066" Dia × 0.150" L). PCB footprints, lead spacing, and assembly processes are interchangeable.

Q: What compliance status applies to both parts?

A: Both parts are RoHS non-compliant and REACH affected. ECCN classification is EAR99 for both components. Verify compliance requirements for your specific application or end-use market.
