Frequently Asked Questions (FAQ)

Q: Can RN55C1691FB14 be used as a direct replacement for RN55C1691FBSL?

A: Yes. Both parts are identical in electrical specifications (1.69 kOhms, ±1%, 0.125W), composition (metal film), temperature characteristics (±50ppm/°C, -65°C to 175°C operating range), and mechanical form factor (axial, 0.090" Dia × 0.240" L). They are both manufactured by Vishay Dale within the military RN55 series.

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

A: No. Both parts share identical RoHS non-compliant and REACH Affected status. Both are certified to MIL-R-10509/7 and feature flame retardant coating, military classification, moisture resistance, and safety certification.

Q: What is the difference between RN55C1691FBSL and RN55C1691FB14?

A: These part numbers represent different packaging or distribution variants from Vishay Dale. All electrical, mechanical, and performance specifications are identical. The difference is administrative rather than functional.

Q: Can these parts be used interchangeably in PCB assembly?

A: Yes. Identical axial package dimensions (0.090" Dia × 0.240" L) and lead configuration ensure mechanical and electrical interchangeability in through-hole PCB designs without modification to board layout or assembly procedures.

Q: Which part should I select based on availability?

A: Selection may be based on inventory status. RN55C1691FB14 currently has higher stock (951 units) compared to RN55C1691FBSL (800 units). Both are active production parts with no planned discontinuation.
