RCS3216F6981CS Equivalent & Substitute Parts

Part Overview

The RCS3216F6981CS is a 6.98 kOhms ±1% 0.25W chip resistor in 1206 (3216 Metric) package manufactured by Samsung Electro-Mechanics. This thick film resistor features anti-sulfur and moisture-resistant properties, operating across -55°C to 155°C with a temperature coefficient of ±100ppm/°C. The component is RoHS3 compliant and carries MSL Level 1 (Unlimited) moisture sensitivity rating. With 901 pieces in stock and Active product status, this part serves as a reference for identifying functionally equivalent alternatives from other manufacturers.

Substitute parts are necessary when primary component availability is limited, when design requirements mandate specific manufacturer certifications (such as AEC-Q200 for automotive applications), or when supply chain optimization requires qualified alternatives from multiple sources.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RCS3216F6981CS is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 6.98 kOhms
• 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
• RoHS3 compliance
• MSL Level 1 (Unlimited)

All four substitute parts listed meet these mandatory criteria. Physical dimensions vary slightly between manufacturers (length ranges from 0.122" to 0.126", height from 0.024" to 0.030"), which is within acceptable tolerance for 1206 package specifications and does not affect electrical performance or PCB footprint compatibility.

Additional features such as anti-sulfur protection (RCS3216F6981CS) or automotive AEC-Q200 certification (CRCW12066K98FKEA, ERJ-8ENF6981V) represent enhanced capabilities beyond the base specification and do not disqualify parts from substitution.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Active Product Status):

CR1206-FX-6981ELF (Bourns Inc.) and RC1206FR-076K98L (YAGEO) are recommended as primary substitutes. Both maintain Active product status, ensuring long-term availability and continued manufacturer support. CR1206-FX-6981ELF offers moisture-resistant thick film construction with 15,852 units in stock. RC1206FR-076K98L provides moisture-resistant properties with the highest inventory level at 24,264 units.

Automotive-Qualified Substitute:

CRCW12066K98FKEA (Vishay Dale) is specified for applications requiring AEC-Q200 automotive qualification. This part carries Active status and maintains all electrical and thermal specifications identical to the primary part. With 17,994 units in stock, it provides both qualification compliance and supply security.

Legacy Substitute (Restricted Use):

ERJ-8ENF6981V (Panasonic Electronic Components) carries "Not For New Designs" product status. While electrically and mechanically equivalent with the highest inventory (44,024 units), this part is suitable only for replacement, repair, or continuation of existing designs. New circuit designs should not incorporate this part number.

All substitute parts are RoHS3 compliant and carry MSL Level 1 (Unlimited) rating, matching the environmental and handling requirements of the primary part.

Frequently Asked Questions (FAQ)

Q: Can I substitute CR1206-FX-6981ELF for RCS3216F6981CS in my design?

A: Yes. Both parts share identical electrical specifications (6.98 kOhms ±1%, 0.25W, ±100ppm/°C, -55°C to 155°C), composition (thick film), and package (1206). Physical dimensions vary slightly (CR1206-FX-6981ELF height 0.030" vs. RCS3216F6981CS height 0.026"), but remain within 1206 package tolerance and do not affect PCB footprint compatibility.

Q: What is the difference between the Samsung RCS3216F6981CS and the Vishay CRCW12066K98FKEA?

A: Both parts are electrically identical. The primary difference is that CRCW12066K98FKEA carries AEC-Q200 automotive qualification, making it suitable for automotive applications requiring this certification. The Samsung part features anti-sulfur protection as an additional property. Both are RoHS3 compliant with MSL Level 1 rating.

Q: Why is ERJ-8ENF6981V marked "Not For New Designs"?

A: This designation indicates that Panasonic has discontinued active development and marketing of this part for new applications. While the part remains electrically and mechanically equivalent, it is reserved for replacement and repair of existing designs. New circuit designs should select from parts with Active status: CR1206-FX-6981ELF, CRCW12066K98FKEA, or RC1206FR-076K98L.

Q: Are all substitute parts available in Tape & Reel packaging?

A: The RCS3216F6981CS is supplied in bulk packaging. All four substitute parts are available in Tape & Reel (TR) packaging, which is standard for automated assembly processes. If bulk packaging is required, consult directly with the respective manufacturers regarding alternative packaging options.

Q: Do the physical dimension variations between manufacturers affect PCB layout?

A: No. All parts conform to the 1206 (3216 Metric) package standard. Length variations (0.122" to 0.126") and height variations (0.024" to 0.030") fall within IEC 60603-7 specifications for this package class and do not require PCB footprint redesign.

Q: Which substitute part offers the best supply availability?

A: ERJ-8ENF6981V (Panasonic) has the highest inventory at 44,024 units. However, due to its "Not For New Designs" status, RC1206FR-076K98L (YAGEO) with 24,264 units is recommended for new designs requiring maximum availability among Active-status parts.

Q: Can I use CRCW12066K98FKEA in non-automotive applications?

A: Yes. AEC-Q200 certification is an additional qualification that does not restrict use to automotive applications. CRCW12066K98FKEA is fully compatible with general industrial and consumer applications and offers the same electrical performance as other substitutes.
