Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RCS3216F27R4CS are qualified based on the following criteria:

Electrical Parameters (Critical):

• Resistance value: 27.4 Ohms
• Tolerance: ±1%
• Power rating: 0.25W (1/4W)
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C

Mechanical Parameters (Critical):

• Package type: 1206 (3216 Metric)
• Number of terminations: 2
• Physical dimensions compatible with 1206 footprint

Compliance Parameters:

• RoHS3 Compliant status
• Moisture Sensitivity Level: 1 (Unlimited)
• REACH Unaffected status

All identified substitute parts meet these core requirements. Variations in height-seated maximum and specific feature sets (anti-sulfur vs. moisture-resistant vs. automotive AEC-Q200) do not affect functional substitution when electrical and mechanical parameters align.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Active Product Status):

CR1206-FX-27R4ELF (Bourns Inc.) and RC1206FR-0727R4L (YAGEO) are recommended as primary substitutes. Both maintain Active product status, ensuring long-term availability and supply chain stability. These parts are functionally equivalent to the RCS3216F27R4CS with identical electrical specifications and package compatibility.

Automotive-Qualified Alternative:

CRCW120627R4FKEA (Vishay Dale) qualifies as a substitute for applications requiring AEC-Q200 automotive certification. This part meets all electrical and mechanical parameters while providing automotive-grade reliability assurance.

Legacy Consideration:

ERJ-8ENF27R4V (Panasonic Electronic Components) carries "Not For New Designs" status. While electrically and mechanically compatible, this part should be used only for legacy system maintenance or repair applications where supply continuity from existing inventory is required.

Compliance Verification:

All substitute parts maintain ROHS3 compliance, Moisture Sensitivity Level 1 (Unlimited), and REACH Unaffected status, matching the regulatory profile of the RCS3216F27R4CS.

Frequently Asked Questions (FAQ)

Q: Can CR1206-FX-27R4ELF directly replace RCS3216F27R4CS in existing designs?

A: Yes. Both parts share identical electrical specifications (27.4 Ohms ±1%, 0.25W), temperature characteristics (±100ppm/°C, -55°C to 155°C), and 1206 package format. The maximum seated height difference (0.75mm vs. 0.66mm) remains within standard PCB assembly tolerances for 1206 components.

Q: What is the difference between moisture-resistant and anti-sulfur features?

A: The RCS3216F27R4CS includes both anti-sulfur and moisture-resistant construction. CR1206-FX-27R4ELF and RC1206FR-0727R4L specify moisture-resistant features. Both feature sets provide environmental protection; anti-sulfur specifically addresses sulfur contamination in industrial environments. Feature differences do not affect electrical substitution.

Q: Why is ERJ-8ENF27R4V marked "Not For New Designs"?

A: This designation indicates the manufacturer has discontinued active development for this part number. While the component remains functionally equivalent and available in inventory (223,904 pieces), new designs should specify active alternatives like CR1206-FX-27R4ELF or RC1206FR-0727R4L to ensure long-term supply availability.

Q: Are all substitute parts suitable for automotive applications?

A: Only CRCW120627R4FKEA carries AEC-Q200 automotive qualification. For automotive applications requiring formal qualification, specify CRCW120627R4FKEA. Other substitutes meet general industrial specifications but lack automotive certification.

Q: What packaging formats are available for these substitutes?

A: All substitute parts are supplied in Tape & Reel (TR) format, standard for high-volume SMD assembly. The RCS3216F27R4CS packaging format is not specified in the provided data but does not affect functional compatibility.

Q: Can height differences between substitute parts affect PCB assembly?

A: Maximum seated heights range from 0.024" (CRCW120627R4FKEA) to 0.030" (CR1206-FX-27R4ELF). These variations fall within standard 1206 component tolerances and do not require PCB redesign. Verify with assembly equipment specifications if height-critical applications exist.

Q: Do all parts meet the same compliance standards?

A: Yes. All listed substitutes maintain ROHS3 compliance, Moisture Sensitivity Level 1 (Unlimited), and REACH Unaffected status, ensuring regulatory equivalence for global applications.
