Substitute Part Grouping Explanation

Substitute parts for the RLR05C3900GSBSL are identified based on strict parametric equivalence across the following critical criteria:

• Resistance value: 390 Ohms (exact match required)
• Tolerance: ±2% (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 × 0.150" L (exact match required)
• Military specification compliance: MIL-PRF-39017/05 (exact match required)
• Failure rate classification: S (0.001%) (exact match required)

The RLR05C3900GSB14 meets all parametric requirements for direct substitution. Both parts share identical electrical characteristics, mechanical dimensions, and military qualification standards, differing only in packaging designation suffix.

Parameter Comparison

Engineering Selection Recommendations

Both the RLR05C3900GSBSL and RLR05C3900GSB14 are active production components with identical electrical performance, mechanical compatibility, and military qualification status. Selection between these parts should be based on inventory availability and procurement lead times. The RLR05C3900GSB14 currently maintains higher stock levels (1059 pieces versus 850 pieces), which may provide supply chain advantages for high-volume applications. Both parts maintain RoHS non-compliance status and REACH-affected classification, with identical ECCN (EAR99) and HTSUS (8533.21.0090) designations, ensuring equivalent regulatory treatment in procurement and export documentation.

Frequently Asked Questions (FAQ)

Q: Can RLR05C3900GSB14 be used as a direct replacement for RLR05C3900GSBSL?

A: Yes. Both parts are parametrically identical across all electrical and mechanical specifications. The suffix designation difference reflects packaging or distribution channel variation only, with no impact on circuit performance or physical fit.

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

A: No. Both parts meet identical MIL-PRF-39017/05 requirements with S-class (0.001%) failure rate ratings. Military qualification and performance characteristics are equivalent.

Q: Do these parts have identical physical dimensions for PCB mounting?

A: Yes. Both parts share identical axial package dimensions of 0.066" diameter × 0.150" length (1.68mm × 3.81mm), ensuring identical footprint compatibility and lead spacing on through-hole PCB designs.

Q: What is the significance of the suffix difference between GSBSL and GSB14?

A: The suffix designates packaging or distribution channel classification. This does not affect electrical performance, mechanical compatibility, or military specification compliance. Both variants are sourced from Vishay Dale and meet identical performance standards.

Q: Are temperature coefficient and operating range specifications identical?

A: Yes. Both parts specify ±100ppm/°C temperature coefficient and -65°C to 150°C operating temperature range, ensuring identical thermal performance characteristics across all operating conditions.
