Substitute Part Grouping Explanation

Substitute parts for the RLR05C2002FSM22 are qualified based on strict parametric equivalence across the following criteria:

• Identical resistance value: 20 kOhms
• Identical tolerance: ±1%
• Identical power rating: 0.125W (1/8W)
• Identical composition: Metal Film
• Identical package: Axial
• Identical temperature coefficient: ±100ppm/°C
• Identical operating temperature range: -65°C to 150°C
• Identical military series designation: MIL-PRF-39017/05, RLR05
• Identical features: Military, Moisture Resistant, Weldable
• Identical failure rate classification: S (0.001%)

The RLR05C2002FSB14 meets all substitution criteria as a parametric equivalent within the RLR05 military resistor series.

Parameter Comparison

Engineering Selection Recommendations

Both parts maintain identical compliance status: RoHS non-compliant and REACH Affected. Military qualification per MIL-PRF-39017/05 is maintained across both part numbers.

Frequently Asked Questions (FAQ)

Q: Can RLR05C2002FSB14 be used as a direct replacement for RLR05C2002FSM22?

A: Yes. Both parts are parametric equivalents with identical resistance, tolerance, power rating, temperature coefficient, operating temperature range, package type, and military series designation. Direct substitution is supported without circuit redesign.

Q: Are there any differences in reliability or failure rate between these parts?

A: No. Both parts carry identical failure rate classification of S (0.001%) and are manufactured to the same MIL-PRF-39017/05 military specification.

Q: Do these parts have the same physical dimensions?

A: Yes. Both parts measure 0.066" diameter by 0.150" length (1.68mm x 3.81mm) in axial configuration with two terminations.

Q: What is the difference between the part numbers RLR05C2002FSM22 and RLR05C2002FSB14?

A: The part numbers differ in their suffix designations (FSM22 versus FSB14), which typically indicate different manufacturing batches or tape/reel configurations within the same product line. All electrical and mechanical parameters remain identical.

Q: Are both parts suitable for military applications?

A: Yes. Both parts are qualified to MIL-PRF-39017/05 specification and feature military-grade construction with moisture resistance and weldable leads.

Q: What compliance certifications apply to these parts?

A: Both parts are RoHS non-compliant and REACH Affected. Compliance requirements should be verified against specific application and regional regulations.
