• Matching tolerance: ±1%
• Equivalent power rating: 0.25W (1/4W)
• 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: 0.090" Dia × 0.250" L (2.29mm × 6.35mm)
• Same series classification: Military, MIL-PRF-39017/01, RLR07
• Matching features: Military, Moisture Resistant, Weldable
• Equivalent failure rate: S (0.001%)

Parameter Comparison

Engineering Selection Recommendations

Both RLR07C3922FSRSL23 and RLR07C3922FSB14 maintain active product status with full military compliance under MIL-PRF-39017/01. Selection between these parts should be based on inventory availability and procurement timelines. The RLR07C3922FSB14 currently maintains higher inventory levels at 1026 units compared to 683 units for the primary part number, making it suitable for applications where extended lead times must be minimized. Both parts carry identical RoHS non-compliance status, REACH affected designation, EAR99 ECCN classification, and HTSUS code 8533.21.0090. No electrical or mechanical differentiation exists between these components.

Frequently Asked Questions (FAQ)

Q: Can RLR07C3922FSB14 be used as a direct replacement for RLR07C3922FSRSL23?

A: Yes. Both parts are parametrically equivalent across all electrical and mechanical specifications, including resistance value, tolerance, power rating, temperature coefficient, operating temperature range, package configuration, and physical dimensions. They are interchangeable in circuit applications.

Q: What is the difference between these two part numbers?

A: The part numbers differ only in their packaging or distribution designation suffix (FSRSL23 versus FSB14). All functional and performance characteristics are identical. The difference reflects supplier packaging or lot tracking conventions rather than component specification variations.

Q: Are both parts suitable for military and aerospace applications?

A: Yes. Both parts are classified under the military RLR07 series per MIL-PRF-39017/01 and carry identical military-grade specifications including moisture resistance, weldability, and failure rate classification of S (0.001%).

Q: What are the physical dimensions, and will they fit existing PCB layouts?

A: Both parts share identical axial package dimensions of 0.090" diameter × 0.250" length (2.29mm × 6.35mm). They will fit identically in existing through-hole PCB layouts designed for the RLR07 series.

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

A: No. Both parts carry identical compliance designations: RoHS non-compliant, REACH affected, EAR99 ECCN, and HTSUS code 8533.21.0090. No differentiation exists in regulatory or export classification status.
