Substitute Part Grouping Explanation

Substitute parts for the RLR05C1000FSS20 are identified based on strict parametric equivalence across all critical electrical and mechanical specifications. The substitution criteria are:

• Resistance value: 100 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 × 0.150" L (exact match required)
• Military classification: MIL-PRF-39017/05, RLR05 series (exact match required)
• Failure rate: S (0.001%) (exact match required)

The RLR05C1000FSB14 meets all these criteria and is classified as a parametric equivalent.

Parameter Comparison

Engineering Selection Recommendations

Both the RLR05C1000FSS20 and RLR05C1000FSB14 are active production components manufactured by Vishay Dale with identical electrical and mechanical specifications. Selection between these parts should be based on inventory availability and supply chain requirements. Both components carry the same regulatory status (RoHS non-compliant, REACH Affected, EAR99 classification) and are suitable for military applications requiring MIL-PRF-39017/05 compliance. The failure rate classification of S (0.001%) applies to both parts, ensuring equivalent reliability performance in circuit applications.

Frequently Asked Questions (FAQ)

Q: Can RLR05C1000FSB14 be used as a direct replacement for RLR05C1000FSS20?

A: Yes. Both parts are parametric equivalents with identical resistance value (100 Ohms), tolerance (±1%), power rating (0.125W), temperature coefficient (±100ppm/°C), operating temperature range (-65°C to 150°C), axial package configuration, and physical dimensions (0.066" Dia × 0.150" L). They are interchangeable in circuit applications.

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

A: No. Both parts conform to MIL-PRF-39017/05 specifications and are classified within the RLR05 military resistor series with identical failure rate ratings (S, 0.001%).

Q: What is the significance of the different part number suffixes (FSS20 vs. FSB14)?

A: The suffix variations indicate different manufacturing batches or tape/reel configurations within the same parametric family. The electrical and mechanical specifications remain identical.

Q: Are both parts subject to the same regulatory requirements?

A: Yes. Both components share identical RoHS status (non-compliant), REACH status (Affected), ECCN classification (EAR99), and HTSUS code (8533.21.0090).

Q: Which part should be selected based on availability?

A: Selection should be based on current inventory levels and supply chain lead times. The RLR05C1000FSB14 currently has higher inventory (1471 pieces) compared to the RLR05C1000FSS20 (995 pieces), which may influence procurement decisions for high-volume applications.
