Key Parameters

Substitute Part Grouping Explanation

Substitution of the RR0306S-103-FNH is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Resistance value: 10 kOhm
• Tolerance: ±1%
• Power rating: 1/20W (0.05W)

Physical Parameters:

• Package designation: 0201 (0603 Metric)
• Composition: Thick Film
• Termination count: 2

Compliance & Regulatory Parameters:

• Moisture Sensitivity Level: MSL 1 (Unlimited)
• REACH Status: REACH Unaffected
• Product Status: Active

Substitute parts must match all electrical specifications, physical package dimensions, and regulatory compliance status. The PFR03S-103-FNH meets these criteria and is classified as a direct equivalent.

Parameter Comparison

Regulatory Compliance: Both parts are REACH unaffected and carry MSL 1 rating, confirming suitability for standard manufacturing and storage conditions without special moisture control requirements.

Product Lifecycle Status: Both parts maintain active product status, ensuring continued manufacturer support and availability through standard distribution channels.

Packaging Consistency: Both parts are supplied in Tape & Reel format, maintaining compatibility with automated assembly equipment and standard component handling procedures.

Frequently Asked Questions (FAQ)

Q: Can PFR03S-103-FNH be used as a direct replacement for RR0306S-103-FNH?

A: Yes. Both parts are manufactured by Delta Electronics/Cyntec and share identical electrical specifications (10 kOhm ±1% at 1/20W), physical package dimensions (0201), composition (Thick Film), and regulatory compliance status. Direct substitution is supported without circuit modification.

Q: Are there differences in operating temperature performance between these parts?

A: Both parts operate within the -55°C to 125°C temperature range with a temperature coefficient of ±200ppm/°C. This specification applies to both the RR0306S-103-FNH and PFR03S-103-FNH, ensuring equivalent thermal performance across the specified operating envelope.

Q: What is the significance of MSL 1 rating for these components?

A: MSL 1 (Moisture Sensitivity Level 1) indicates unlimited shelf life without moisture control requirements. These components do not require special desiccant packaging, controlled humidity storage, or bake-out procedures prior to assembly, simplifying inventory management and reducing handling costs.

Q: Are both parts suitable for automated pick-and-place assembly?

A: Yes. Both the RR0306S-103-FNH and PFR03S-103-FNH are supplied in Tape & Reel packaging format, which is the standard format for automated surface-mount assembly equipment. The 0201 package size and two-termination configuration are compatible with standard feeder systems and placement equipment.

Q: What is the difference between the RR0306S and PFR03S base product numbers?

A: The base product numbers identify different product series within the Delta Electronics/Cyntec resistor portfolio. However, the RR0306S-103-FNH and PFR03S-103-FNH are functionally equivalent for the specified 10 kOhm ±1% 1/20W 0201 application. The series designation does not affect electrical or mechanical compatibility.

Q: Are these parts RoHS compliant?

A: The PFR03S-103-FNH is confirmed as ROHS3 compliant. Both parts are REACH unaffected, confirming compliance with current environmental and hazardous substance regulations applicable to electronic components.
