Substitute Part Grouping Explanation

Substitute parts for the RLR05C2002FSM23 are identified through strict parametric matching. The following criteria determine substitution eligibility:

• Resistance value: 20 kOhms (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 x 0.150" L (exact match required)
• Military qualification: MIL-PRF-39017/05 series (exact match required)

The RLR05C2002FSB14 meets all parametric requirements and is classified as a parametric equivalent. Both parts share identical electrical and mechanical specifications, military qualification standards, and performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

Both the RLR05C2002FSM23 and RLR05C2002FSB14 are active production parts manufactured by Vishay Dale under the military-qualified RLR05 series. Selection between these parts should be based on inventory availability and supply chain requirements. The RLR05C2002FSB14 currently has higher inventory availability (2064 units) compared to the RLR05C2002FSM23 (854 units). Both parts maintain identical compliance status: RoHS non-compliant, REACH affected, and ECCN EAR99 classification. No technical differentiation exists between these parts for circuit design purposes.

Frequently Asked Questions (FAQ)

Q: Can RLR05C2002FSB14 be used as a direct replacement for RLR05C2002FSM23?

A: Yes. Both parts are parametric equivalents with identical electrical specifications (20 kOhms ±1%), power rating (0.125W), temperature characteristics (±100ppm/°C, -65°C to 150°C), and physical dimensions (0.066" Dia x 0.150" L). Both are military-qualified under MIL-PRF-39017/05 with identical failure rates and features.

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

A: No. Both parts are qualified to the same military standard (MIL-PRF-39017/05) and belong to the RLR05 series. They share identical failure rate classifications (S, 0.001%) and military features including moisture resistance and weldability.

Q: Do these parts have the same physical footprint?

A: Yes. Both parts have identical axial package dimensions of 0.066" diameter by 0.150" length (1.68mm x 3.81mm). They are mechanically interchangeable in PCB layouts and through-hole applications.

Q: What is the difference between the part numbers RLR05C2002FSM23 and RLR05C2002FSB14?

A: The part numbers differ in their suffix designations (FSM23 versus FSB14), which typically indicate different manufacturing batches or procurement specifications within Vishay Dale's military resistor product line. The electrical and mechanical specifications remain identical.

Q: Are both parts RoHS compliant?

A: No. Both the RLR05C2002FSM23 and RLR05C2002FSB14 are RoHS non-compliant. Both are REACH affected and classified as EAR99 for export control purposes.
