Key Parameters

Substitute Part Grouping Explanation

Substitution within the RLR07 series is determined by matching the following critical parameters:

• Resistance value: 221 Ohms
• Tolerance: ±1%
• Power rating: 0.25W (1/4W)
• Composition: Metal Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -65°C to 150°C
• Package: Axial
• Physical dimensions: 0.090" Dia x 0.250" L
• Series compliance: MIL-PRF-39017/01, RLR07

The RLR07C2210FSB14 meets all these criteria and is classified as a direct substitute. Both parts share identical electrical specifications and mechanical form factors, differing only in failure rate classification.

Parameter Comparison

Engineering Selection Recommendations

Both RLR07C2210FMB14 and RLR07C2210FSB14 are active military-grade resistors manufactured by Vishay Dale under MIL-PRF-39017/01 specifications. Selection between these parts should be based on application reliability requirements and inventory availability. The RLR07C2210FSB14 offers a lower failure rate (0.001% versus 1%), making it suitable for high-reliability applications where extended operational life is critical. Both parts maintain identical electrical performance and mechanical compatibility, ensuring direct interchangeability in circuit designs. RoHS non-compliance status is consistent across both parts, and REACH compliance applies to both.

Frequently Asked Questions (FAQ)

Q: Can RLR07C2210FSB14 be used as a direct replacement for RLR07C2210FMB14?

A: Yes. Both parts are electrically and mechanically identical, sharing the same resistance value (221 Ohms), tolerance (±1%), power rating (0.25W), temperature coefficient (±100ppm/°C), operating range (-65°C to 150°C), and axial package dimensions (0.090" Dia x 0.250" L). The only difference is the failure rate classification.

Q: What is the significance of the failure rate difference between these parts?

A: The RLR07C2210FMB14 has a failure rate of M (1%), while the RLR07C2210FSB14 has a failure rate of S (0.001%). This difference reflects the expected percentage of parts that may fail under specified conditions over a given time period. Applications requiring higher reliability should specify the lower failure rate variant.

Q: Are both parts compliant with military specifications?

A: Both parts comply with MIL-PRF-39017/01 military specifications and are part of the RLR07 series. Both are classified as active products by Vishay Dale.

Q: What are the physical constraints for installation?

A: Both parts share identical axial package dimensions of 0.090" diameter by 0.250" length (2.29mm x 6.35mm), with two terminations. They are suitable for through-hole mounting on standard PCB layouts without modification.

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

A: Both parts have identical RoHS non-compliance status and REACH compliance status. Neither part is subject to moisture sensitivity level (MSL) classification. Environmental operating specifications are identical across both variants.
