Key Parameters

Substitute Part Grouping Explanation

The RLR05C33R2FSB14 is classified as a parametric equivalent to the RLR05C33R2FSBSL. Substitution eligibility is determined by the following critical parameters:

• Resistance value: 33.2 Ohms (exact match required)
• Tolerance: ±1% (exact match required)
• Power rating: 0.125W / 1/8W (exact match required)
• Composition: Metal Film (exact match required)
• Temperature coefficient: ±100ppm/°C (exact match required)
• Operating temperature range: -65°C to 150°C (exact match required)
• Package type: Axial (exact match required)
• Physical dimensions: 0.066" Dia x 0.150" L (exact match required)
• Military series compliance: MIL-PRF-39017/05, RLR05 (exact match required)

Both parts share identical electrical performance characteristics, mechanical form factor, and military qualification status, making them directly interchangeable in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

Both the RLR05C33R2FSBSL and RLR05C33R2FSB14 maintain active product status with identical military qualification under MIL-PRF-39017/05. Selection between these parts should be based on procurement availability and lead time requirements. The RLR05C33R2FSB14 currently maintains higher inventory levels (1545 units versus 865 units), which may provide advantages for high-volume production schedules or expedited delivery requirements. Both parts carry identical compliance designations (RoHS non-compliant, REACH Affected, ECCN EAR99) and are suitable for military and aerospace applications requiring moisture-resistant, weldable metal film resistor construction.

Frequently Asked Questions (FAQ)

Q: Can RLR05C33R2FSB14 be used as a direct replacement for RLR05C33R2FSBSL?

A: Yes. Both parts are identical in all critical electrical and mechanical parameters: 33.2 Ohm resistance, ±1% tolerance, 0.125W power rating, metal film composition, ±100ppm/°C temperature coefficient, -65°C to 150°C operating range, and axial package configuration. They are directly interchangeable.

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

A: No. Both parts comply with MIL-PRF-39017/05 specification and carry identical failure rate classification (S, 0.001%), RoHS status, REACH status, and export control designations.

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

A: The part numbers differ only in their suffix designations (FSBSL versus FSB14). The electrical and mechanical specifications remain identical. The suffix variation reflects internal Vishay Dale product line management but does not affect circuit performance or compatibility.

Q: Are physical dimensions identical between the two parts?

A: Yes. Both parts measure 0.066" diameter by 0.150" length (1.68mm x 3.81mm) and feature identical axial package geometry with two terminations.

Q: Which part should be selected for new designs?

A: Either part is suitable for new designs. Selection should be based on current inventory availability and procurement lead times. Both maintain active product status and identical military specifications.
