Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC0603F331CS is determined by strict alignment of the following critical parameters:

Electrical Specifications: Resistance value (330 Ohms), tolerance (±1%), and power rating (0.05W / 1/20W) must be identical. Composition type (Thick Film) must match.

Mechanical Compatibility: Package designation (0201 / 0603 Metric), physical dimensions (0.024" L x 0.012" W / 0.60mm x 0.30mm), and maximum seated height (0.010" / 0.26mm) must be equivalent to ensure PCB footprint compatibility and assembly process compatibility.

Compliance & Certification: RoHS3 compliance and MSL 1 rating are mandatory. REACH Unaffected and EAR99 ECCN status must be maintained.

Allowed Variations: Operating temperature range may extend beyond the original specification (higher maximum temperature acceptable). Temperature coefficient may differ within industry-standard ranges for thick film resistors. Packaging format (Cut Tape vs. Tape & Reel) does not affect electrical or mechanical substitution eligibility.

Engineering Selection Recommendations

The CRCW0201330RFKED (Vishay Dale) qualifies as a direct substitute for the RC0603F331CS (Samsung Electro-Mechanics) based on the following engineering criteria:

Electrical Equivalence: Both components provide identical resistance (330 Ohms), tolerance (±1%), and power rating (0.05W). Thick film composition ensures functional equivalence in circuit operation.

Mechanical Compatibility: Identical package designation (0201 / 0603 Metric), physical dimensions, and seated height confirm PCB footprint compatibility and assembly process compatibility without design modification.

Compliance Alignment: Both components maintain ROHS3 compliance, MSL 1 rating, REACH Unaffected status, and EAR99 ECCN classification, ensuring regulatory and supply chain compatibility.

Extended Operating Range: The CRCW0201330RFKED provides an extended maximum operating temperature (-55°C ~ 155°C versus -55°C ~ 125°C), which does not restrict substitution and may provide additional thermal margin in applications.

Temperature Coefficient Difference: The CRCW0201330RFKED exhibits a lower temperature coefficient (±100ppm/°C versus ±250ppm/°C). This represents improved temperature stability and does not restrict substitution eligibility.

Active Product Status: Both components maintain Active product status, confirming ongoing manufacturing availability and supply chain support.

Frequently Asked Questions (FAQ)

Q: Can CRCW0201330RFKED replace RC0603F331CS in existing designs?

A: Yes. Both components share identical electrical specifications (330 Ohms ±1%, 0.05W), mechanical dimensions (0201 package, 0.024" x 0.012"), and compliance certifications (RoHS3, MSL 1). Direct substitution is supported without circuit design modification.

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

A: The CRCW0201330RFKED operates across a wider temperature range (-55°C ~ 155°C versus -55°C ~ 125°C) and exhibits a lower temperature coefficient (±100ppm/°C versus ±250ppm/°C). These differences do not restrict substitution and indicate improved temperature stability in the Vishay part.

Q: Does packaging format (Cut Tape vs. Tape & Reel) affect substitution?

A: No. Packaging format affects supply chain logistics and assembly handling but does not impact electrical or mechanical substitution eligibility. Both formats contain identical components.

Q: Are both parts RoHS3 compliant?

A: Yes. Both RC0603F331CS and CRCW0201330RFKED maintain full RoHS3 compliance with MSL 1 (Unlimited) moisture sensitivity rating, confirming regulatory equivalence.

Q: What is the basis for substitution eligibility?

A: Substitution is based on identical resistance value, tolerance, power rating, composition type, package designation, physical dimensions, seated height, and compliance certifications. Operating temperature range extension and temperature coefficient improvement do not restrict substitution.
