Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RCS3216F3090CS is determined by strict alignment of the following parameters:

Critical Matching Parameters:

• Resistance value: 309 Ohms
• Tolerance: ±1%
• Power rating: 0.25W (1/4W)
• Package: 1206 (3216 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C
• Number of terminations: 2
• RoHS compliance: ROHS3 Compliant
• Moisture sensitivity level: 1 (Unlimited)

All identified substitute parts meet these electrical and mechanical criteria. Variations in physical dimensions (length, width, height) within standard tolerances and differences in packaging format (Tape & Reel versus bulk) do not affect functional equivalence. Product status and specific feature sets (such as automotive AEC-Q200 certification) are noted for application-specific selection but do not disqualify substitution based on core electrical parameters.

Parameter Comparison

Engineering Selection Recommendations

CRCW1206309RFKEA (Vishay Dale): This substitute is recommended for applications requiring automotive-grade components. The part carries AEC-Q200 certification and maintains Active product status, ensuring long-term availability and supply chain stability. Physical dimensions and electrical performance are equivalent to the RCS3216F3090CS.

RC1206FR-07309RL (YAGEO): This substitute is suitable for general industrial and consumer applications. The part maintains Active product status with moisture-resistant properties matching the original component. Inventory availability is substantial, supporting high-volume production requirements.

ERJ-8ENF3090V (Panasonic Electronic Components): This substitute carries AEC-Q200 automotive certification but is designated as Not For New Designs. Use of this part is limited to legacy system maintenance, repair, and replacement applications where existing designs already incorporate this component. New design implementations should select alternatives with Active product status.

All three substitutes comply with ROHS3 and REACH requirements, matching the environmental and regulatory compliance profile of the original RCS3216F3090CS.

Frequently Asked Questions (FAQ)

Q: Can CRCW1206309RFKEA replace RCS3216F3090CS in any application?

A: Yes. Both components share identical electrical specifications (309 Ohms ±1%, 0.25W), operate across the same temperature range (-55°C ~ 155°C), and are packaged in 1206 (3216 Metric) format. The CRCW1206309RFKEA includes automotive AEC-Q200 certification, which provides additional qualification for automotive applications but does not restrict use in general applications.

Q: What is the difference between the physical dimensions listed for each part?

A: Minor variations in length, width, and height (for example, RCS3216F3090CS at 0.126" L vs. RC1206FR-07309RL at 0.122" L) fall within standard manufacturing tolerances for 1206 package components. These variations do not affect PCB layout compatibility or functional performance.

Q: Why is ERJ-8ENF3090V marked as "Not For New Designs"?

A: This designation indicates that Panasonic has discontinued active development and marketing of this product line. While the component remains functionally equivalent and available in inventory, new circuit designs should prioritize parts with Active status (CRCW1206309RFKEA or RC1206FR-07309RL) to ensure long-term supply chain continuity.

Q: Are packaging format differences (Tape & Reel vs. bulk) significant for substitution?

A: Packaging format affects logistics, handling, and automated assembly processes but does not impact electrical or mechanical compatibility. Selection between Tape & Reel and bulk packaging depends on production volume and assembly equipment requirements, not component equivalence.

Q: Do all substitutes meet the same compliance standards as the original RCS3216F3090CS?

A: Yes. All identified substitutes are ROHS3 Compliant, REACH Unaffected, and carry MSL Rating 1 (Unlimited), matching the compliance profile of the original component.
