Engineering Selection Recommendations

Both the RLR07C3320FSBSL and RLR07C3320FSB14 are active production components manufactured by Vishay Dale with identical electrical and mechanical specifications. Selection between these parts should be based on procurement availability and lead time requirements. The RLR07C3320FSB14 currently maintains higher inventory levels (889 units versus 713 units), which may provide advantages for expedited procurement scenarios. Both parts comply with MIL-PRF-39017/01 military specifications and maintain equivalent reliability ratings. Neither part is RoHS compliant, and both are REACH affected with EAR99 export classification. For applications requiring military-grade precision resistors with moisture resistance and weldability in the 332 Ohm, ±1%, 0.25W category, either part provides equivalent performance.

Frequently Asked Questions (FAQ)

Q: Can RLR07C3320FSB14 be used as a direct replacement for RLR07C3320FSBSL?

A: Yes. Both parts are identical in all electrical parameters (resistance, tolerance, power rating, temperature coefficient, operating temperature range) and mechanical specifications (package type, dimensions, terminations). They are from the same military series (MIL-PRF-39017/01, RLR07) and share identical features and failure rates.

Q: Are there any differences in military compliance or certifications?

A: No. Both parts meet identical military specifications under MIL-PRF-39017/01 and carry the same failure rate classification of S (0.001%). Both maintain equivalent compliance status for REACH and export classification (EAR99).

Q: What is the difference between the part numbers RLR07C3320FSBSL and RLR07C3320FSB14?

A: The part numbers differ only in their suffix designations (SL versus 14). These designations typically indicate packaging or distribution channel variations rather than electrical or mechanical differences. All core specifications remain identical.

Q: Can these resistors be used in high-temperature applications?

A: Yes. Both parts are rated for operating temperatures from -65°C to 150°C with a temperature coefficient of ±100ppm/°C, making them suitable for harsh environment applications within this temperature range.

Q: Are these parts suitable for military or aerospace applications?

A: Yes. Both parts are military-grade components compliant with MIL-PRF-39017/01 specifications. They feature moisture resistance and weldability, which are standard requirements for military and aerospace applications. However, specific application requirements should be verified against your system specifications.

Q: What is the moisture resistance rating?

A: Both parts are classified as moisture resistant as part of their military-grade construction. Specific moisture sensitivity levels are not applicable to these axial through-hole components.
