Substitute Part Grouping Explanation

Substitution eligibility for the RLR05C2000FMBSL is determined by strict equivalence across the following critical parameters:

• Resistance value: 200 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)
• Termination count: 2 (exact match required)
• Military series compliance: MIL-PRF-39017/05, RLR05 (exact match required)

The identified substitute part RLR05C2000FSB14 meets all electrical and mechanical parameters. The primary distinction between the main part and substitute is the failure rate specification: RLR05C2000FMBSL carries an M-level failure rate (1%), while RLR05C2000FSB14 carries an S-level failure rate (0.001%), indicating superior reliability performance under MIL-PRF-39017/05 standards.

Parameter Comparison

Engineering Selection Recommendations

Both RLR05C2000FMBSL and RLR05C2000FSB14 are active production components from Vishay Dale with identical electrical and mechanical specifications. Selection between these parts should be based on the following factors:

RLR05C2000FMBSL is appropriate for applications where the M-level failure rate (1%) meets reliability requirements and inventory availability is sufficient.

RLR05C2000FSB14 is appropriate for applications requiring enhanced reliability performance, as evidenced by the S-level failure rate (0.001%), which represents a 1000-fold improvement in failure rate specification. This part also offers greater current inventory availability (1060 units versus 643 units).

Both parts maintain identical compliance status: RoHS non-compliant, REACH Affected, and ECCN EAR99 classification. No compliance advantage exists between the two options.

Frequently Asked Questions (FAQ)

Q: Can RLR05C2000FSB14 be used as a direct replacement for RLR05C2000FMBSL?

A: Yes. Both parts are electrically and mechanically identical across all specified parameters: 200 Ohm resistance, ±1% tolerance, 0.125W power rating, metal film composition, ±100ppm/°C temperature coefficient, -65°C to 150°C operating range, and identical axial package dimensions. The only difference is the failure rate specification, where RLR05C2000FSB14 offers superior reliability performance.

Q: What is the significance of the failure rate difference between M (1%) and S (0.001%)?

A: Failure rate is specified under MIL-PRF-39017/05 military standards. The S-level failure rate (0.001%) indicates a lower predicted failure rate compared to the M-level (1%), making RLR05C2000FSB14 suitable for applications with higher reliability demands or extended operational life requirements.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both parts share identical dimensions of 0.066" diameter by 0.150" length (1.68mm × 3.81mm), ensuring compatibility with existing PCB layouts and mechanical assemblies.

Q: Do these parts have different compliance or certification status?

A: No. Both parts carry identical compliance designations: RoHS non-compliant, REACH Affected status, and ECCN EAR99 classification. No regulatory advantage exists between the two options.

Q: Which part should be selected for new designs?

A: Selection depends on reliability requirements. For applications requiring standard military-grade performance, RLR05C2000FMBSL is suitable. For applications requiring enhanced reliability or extended service life, RLR05C2000FSB14 is the appropriate choice due to its superior failure rate specification.
