Substitute Part Grouping Explanation

Substitute parts for the RLR05C1001FSBSL19 are qualified based on strict parametric equivalence across all critical electrical and mechanical specifications. The substitution logic is based on the following key parameters that must remain identical:

• Resistance value: 1 kOhms
• Tolerance: ±1%
• Power rating: 0.125W (1/8W)
• Composition: Metal Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -65°C to 150°C
• Package type: Axial
• Physical dimensions: 0.066" Dia × 0.150" L (1.68mm × 3.81mm)
• Military series classification: MIL-PRF-39017/05, RLR05
• Features: Military, Moisture Resistant, Weldable

The RLR05C1001FSB14 meets all these criteria and is therefore a direct parametric equivalent suitable for substitution in applications requiring the RLR05C1001FSBSL19.

Parameter Comparison

Engineering Selection Recommendations

Both the RLR05C1001FSBSL19 and RLR05C1001FSB14 are active production components from Vishay Dale with identical electrical specifications, mechanical dimensions, and military qualification. Selection between these parts should be based on availability and lead time requirements. Both parts maintain the same RoHS non-compliant and REACH Affected status, ensuring regulatory consistency in applications where these designations are acceptable. The identical failure rate classification (S, 0.001%) and EAR99 export control designation confirm equivalent reliability and compliance profiles for military and aerospace applications.

Frequently Asked Questions (FAQ)

Q: Can RLR05C1001FSB14 be used as a direct replacement for RLR05C1001FSBSL19?

A: Yes. Both parts are parametrically identical across all electrical and mechanical specifications, including resistance value, tolerance, power rating, temperature coefficient, operating temperature range, physical dimensions, and military qualification per MIL-PRF-39017/05.

Q: Are there any differences in the axial package dimensions between these parts?

A: No. Both parts have identical physical dimensions of 0.066" diameter by 0.150" length (1.68mm × 3.81mm), ensuring compatibility with existing PCB layouts and through-hole mounting patterns.

Q: Do both parts meet the same military specifications?

A: Yes. Both the RLR05C1001FSBSL19 and RLR05C1001FSB14 are qualified to MIL-PRF-39017/05 specification and belong to the RLR05 military series with identical moisture-resistant and weldable features.

Q: What is the significance of the different part number suffixes (FSBSL19 vs FSB14)?

A: The suffix variations indicate different packaging or distribution configurations from Vishay Dale. The electrical and mechanical specifications remain identical, making them functionally equivalent for component selection purposes.
