Frequently Asked Questions (FAQ)

Q: Are RN55D3572FBSL and RN55D3572FB14 directly interchangeable?

A: Yes. Both parts share identical electrical specifications (35.7 kOhms ±1%, 0.125W), composition (metal film), temperature characteristics (±100ppm/°C, -65°C to 175°C operating range), and physical dimensions (0.090" Dia × 0.240" L axial package). They are manufactured by the same supplier within the same military series (RN55, MIL-R-10509/7) and meet identical compliance requirements.

Q: What determines substitutability for the RN55D3572FBSL?

A: Substitutability is determined by exact matching of resistance value, tolerance, power rating, composition, temperature coefficient, operating temperature range, package type, physical dimensions, and military specification compliance. All these parameters must align precisely for direct substitution.

Q: Can I use a different resistance value or tolerance?

A: No. The resistance value of 35.7 kOhms and tolerance of ±1% are circuit-critical parameters. Substitutes must match these values exactly. Different values or tolerances will alter circuit performance and are not acceptable substitutes.

Q: Are there any compliance differences between these parts?

A: No. Both parts maintain identical RoHS status (non-compliant), REACH status (Affected), ECCN classification (EAR99), and HTSUS coding (8533.21.0090). Compliance profiles are equivalent.

Q: What is the difference between the part numbers?

A: The part numbers RN55D3572FBSL and RN55D3572FB14 represent different packaging or distribution variants within the same RN55 military series. All electrical and mechanical specifications remain identical. The difference is administrative rather than technical.
