Substitute Part Grouping Explanation

Substitution eligibility for the RLR05C2211FSM23 is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part RLR05C2211FSB14 qualifies as a parametric equivalent based on the following criteria:

• Identical resistance value: 2.21 kOhms
• Matching tolerance: ±1%
• Equivalent power rating: 0.125W (1/8W)
• Same composition: Metal Film
• Identical temperature coefficient: ±100ppm/°C
• Matching operating temperature range: -65°C to 150°C
• Same package configuration: Axial
• Identical physical dimensions: 0.066" Dia × 0.150" L (1.68mm × 3.81mm)
• Same series classification: Military, MIL-PRF-39017/05, RLR05
• Equivalent failure rate: S (0.001%)

Frequently Asked Questions (FAQ)

Q: Can RLR05C2211FSB14 be used as a direct replacement for RLR05C2211FSM23?

A: Yes. Both parts are parametric equivalents with identical resistance, tolerance, power rating, temperature coefficient, operating temperature range, package type, and physical dimensions. They are both classified under the same military series MIL-PRF-39017/05 RLR05 with equivalent failure rates.

Q: Are there any differences in the axial package configuration between these parts?

A: No. Both parts share identical physical dimensions of 0.066" Dia × 0.150" L (1.68mm × 3.81mm) and are configured as two-termination axial components suitable for through-hole PCB mounting.

Q: What is the significance of the different part number suffixes (FSM23 vs FSB14)?

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

Q: Do both parts meet the same military specifications?

A: Yes. Both RLR05C2211FSM23 and RLR05C2211FSB14 are manufactured to MIL-PRF-39017/05 specifications and carry the same military-grade classification with S-level failure rate (0.001%).

Q: Are there any compliance or certification differences between these parts?

A: No. Both parts share identical RoHS status (non-compliant), REACH status (affected), ECCN classification (EAR99), and HTSUS code (8533.21.0090).
