RR0306S-470-FNH Equivalent & Substitute Parts

Part Overview

The RR0306S-470-FNH is a chip resistor manufactured by Delta Electronics/Cyntec, rated at 47 ohms with 1% tolerance and 1/20W (0.05W) power rating in 0201 package form factor. This component is classified as an active product with unlimited moisture sensitivity rating (MSL 1), making it suitable for general electronic applications without moisture-related constraints during storage and assembly.

Substitute parts are identified to provide alternative sourcing options when the primary part number becomes unavailable, while maintaining identical electrical and mechanical specifications required for direct circuit board replacement.

Substitute Part Grouping Explanation

Substitution eligibility for the RR0306S-470-FNH is determined by strict equivalence across the following critical parameters:

Electrical Specifications:

• Resistance value: 47 Ohms (exact match required)
• Tolerance: ±1% (exact match required)
• Power rating: 1/20W / 0.05W (exact match required)

Mechanical Specifications:

• Package designation: 0201 (0603 Metric) (exact match required)
• Composition type: Thick Film (exact match required)
• Termination count: 2 terminations (exact match required)

Compliance & Regulatory:

• Moisture Sensitivity Level: MSL 1 (Unlimited) (exact match required)
• RoHS Status: ROHS3 Compliant (exact match required)
• REACH Status: REACH Unaffected (exact match required)

The substitute part PFR03S-470-FNH meets all specified criteria and is therefore classified as a direct equivalent for circuit board replacement applications.

Parameter Comparison

Engineering Selection Recommendations

Both RR0306S-470-FNH and PFR03S-470-FNH are active products manufactured by Delta Electronics/Cyntec with full ROHS3 compliance and REACH unaffected status. Selection between these parts is based on availability and supply chain considerations rather than technical differentiation.

The PFR03S-470-FNH substitute part provides additional documented specifications including temperature coefficient (±300ppm/°C) and operating temperature range (-55°C ~ 125°C), which may be beneficial for design documentation and thermal analysis purposes.

Both parts carry MSL 1 (Unlimited) moisture sensitivity rating, eliminating moisture-related handling constraints during manufacturing and assembly processes.

Frequently Asked Questions (FAQ)

Q: Can PFR03S-470-FNH be used as a direct replacement for RR0306S-470-FNH on existing circuit boards?

A: Yes. Both parts are electrically and mechanically identical with matching 47 ohm resistance, ±1% tolerance, 1/20W power rating, and 0201 package designation. Direct substitution on circuit boards is supported without design modification.

Q: Are there any compliance differences between the two part numbers?

A: No. Both parts carry identical ROHS3 compliance status and REACH unaffected designation. Regulatory and environmental compliance requirements are met by either part.

Q: What is the significance of MSL 1 (Unlimited) rating for these resistors?

A: MSL 1 indicates unlimited shelf life without moisture-related degradation. These parts do not require special dry-pack storage or baking procedures prior to assembly, simplifying inventory management and procurement logistics.

Q: Are the physical dimensions identical between RR0306S-470-FNH and PFR03S-470-FNH?

A: Yes. Both parts conform to the 0201 (0603 Metric) package standard with identical footprint dimensions of 0.024" L x 0.012" W (0.60mm x 0.30mm) and maximum seated height of 0.010" (0.26mm). PCB layout and assembly tooling compatibility is maintained.

Q: What is the temperature operating range for these resistors?

A: The documented operating temperature range is -55°C to 125°C with a temperature coefficient of ±300ppm/°C. This specification applies to both part numbers and supports operation across industrial and commercial temperature environments.

Q: Can these 47 ohm resistors be used in high-frequency applications?

A: Substitution eligibility is determined by the electrical and mechanical parameters provided. Frequency-dependent performance characteristics are not included in the equivalence criteria and must be evaluated separately based on application-specific requirements.
