Substitute Part Grouping Explanation

Substitution eligibility for the RLR05C2002FMB14 is determined by strict equivalence across the following critical parameters:

• Resistance value: 20 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 configuration: Axial
• Physical dimensions: 0.066" Dia × 0.150" L
• Series classification: RLR05 military-grade resistor

The RLR05C2002FSB14 qualifies as a direct substitute based on identical electrical specifications and mechanical compatibility. Both parts maintain the same base product number (RLR05) and military series designation, with differences limited to failure rate classification and packaging designation codes.

Parameter Comparison

Engineering Selection Recommendations

Both RLR05C2002FMB14 and RLR05C2002FSB14 are active production parts manufactured by Vishay Dale under identical military specifications. Selection between these parts should be based on application-specific reliability requirements and failure rate tolerance levels. The RLR05C2002FSB14 offers a lower failure rate classification (S: 0.001%) compared to the RLR05C2002FMB14 (M: 1%), making it suitable for applications requiring enhanced reliability performance. Both parts maintain identical electrical characteristics, physical dimensions, and compliance certifications (RoHS non-compliant, REACH Affected, ECCN EAR99). Current inventory levels support either selection, with 2064 units of RLR05C2002FSB14 and 1021 units of RLR05C2002FMB14 available.

Frequently Asked Questions (FAQ)

Q: Can RLR05C2002FSB14 be used as a direct replacement for RLR05C2002FMB14?

A: Yes. Both parts are electrically and mechanically equivalent with identical resistance (20 kOhms), tolerance (±1%), power rating (0.125W), temperature coefficient (±100ppm/°C), operating range (-65°C to 150°C), and axial package dimensions (0.066" Dia × 0.150" L). The primary difference is the failure rate classification.

Q: What is the difference between failure rate M and failure rate S?

A: Failure rate M represents 1% per 1000 hours, while failure rate S represents 0.001% per 1000 hours. The RLR05C2002FSB14 with failure rate S provides superior reliability performance for mission-critical applications.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both parts share identical axial package dimensions of 0.066" diameter by 0.150" length (1.68mm × 3.81mm), ensuring mechanical compatibility in PCB layouts and assembly processes.

Q: Do both parts meet the same military specification?

A: Yes. Both RLR05C2002FMB14 and RLR05C2002FSB14 comply with MIL-PRF-39017/05 military specification and belong to the RLR05 series, featuring moisture resistance and weldability.

Q: What are the compliance differences between these parts?

A: Both parts share identical compliance status: RoHS non-compliant, REACH Affected, ECCN EAR99, and HTSUS code 8533.21.0090. No compliance differentiation exists between the two parts.
