Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RCS3216F6811CS is determined by strict equivalence in the following core parameters:

Critical Parameters (Must Match Exactly):

• Resistance value: 6.81 kOhms
• Tolerance: ±1%
• Package / Case: 1206 (3216 Metric)
• Composition: Thick Film
• Temperature Coefficient: ±100ppm/°C
• Operating Temperature Range: -55°C ~ 155°C
• Number of Terminations: 2

Compatible Power Ratings:

• Primary: 0.25W (1/4W) - direct equivalents
• Secondary: 0.75W (3/4W) - higher power rating, electrically compatible for applications not requiring exact power matching

Compliance Requirements: All substitute parts maintain ROHS3 compliance, MSL Level 1, and REACH unaffected status, ensuring regulatory compatibility across industrial and commercial applications.

Substitute parts are grouped by manufacturer and packaging format while maintaining all critical electrical and mechanical parameters.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Active Status, 0.25W Rating):

CR1206-FX-6811ELF (Bourns Inc.) and RC1206FR-076K81L (YAGEO) are recommended as primary substitutes. Both parts maintain active production status, identical electrical specifications, and full regulatory compliance. CR1206-FX-6811ELF offers the highest inventory availability (51,973 pieces) in Tape & Reel format. RC1206FR-076K81L provides Cut Tape & Digi-Reel packaging with substantial inventory (104,244 pieces).

Automotive-Qualified Alternatives:

CRCW12066K81FKEA (Vishay Dale) and RMCF1206FT6K81 (Stackpole Electronics Inc) are AEC-Q200 automotive-qualified equivalents suitable for applications requiring automotive-grade components. Both maintain 0.25W power rating and active production status.

Higher Power Rating Option:

CRCW12066K81FKEAHP (Vishay Dale) provides 0.75W (3/4W) power rating while maintaining all other electrical parameters. This part is suitable for applications where higher power dissipation capability is beneficial, though not required for standard 0.25W designs.

Obsolescence Consideration:

ERJ-8ENF6811V (Panasonic Electronic Components) carries "Not For New Designs" status. While electrically equivalent and currently in stock (88,614 pieces), this part should not be selected for new product designs due to its obsolescence trajectory.

Frequently Asked Questions (FAQ)

Q: Can I substitute the RCS3216F6811CS with any of the listed parts?

A: Direct substitution is possible with CR1206-FX-6811ELF, CRCW12066K81FKEA, RC1206FR-076K81L, and RMCF1206FT6K81. All maintain identical electrical specifications (6.81 kΩ ±1%, 0.25W, 1206 package, ±100ppm/°C). ERJ-8ENF6811V is electrically compatible but marked "Not For New Designs." CRCW12066K81FKEAHP is compatible but features higher 0.75W power rating.

Q: What is the difference between packaging formats (Bulk, Tape & Reel, Cut Tape)?

A: Bulk packaging is suitable for manual assembly or small-volume applications. Tape & Reel format is optimized for automated pick-and-place assembly equipment. Cut Tape & Digi-Reel provides flexibility for both manual and semi-automated processes. All formats contain identical components; selection depends on assembly methodology and volume requirements.

Q: Are automotive-qualified parts (AEC-Q200) required for my application?

A: AEC-Q200 qualification is required only for automotive applications or systems subject to automotive reliability standards. CRCW12066K81FKEA and RMCF1206FT6K81 carry this certification. For non-automotive industrial or commercial applications, standard parts without AEC-Q200 qualification are acceptable.

Q: Can I use CRCW12066K81FKEAHP (0.75W) in place of the 0.25W RCS3216F6811CS?

A: Yes. The 0.75W part is electrically compatible and will function correctly in circuits designed for 0.25W resistors. Higher power rating provides additional thermal margin and is not detrimental to circuit performance. Physical dimensions remain within 1206 package specifications.

Q: Why is ERJ-8ENF6811V marked "Not For New Designs"?

A: This designation indicates the manufacturer has discontinued active development and is transitioning away from this product line. While currently available in inventory, Panasonic recommends alternative parts for new product designs to ensure long-term supply continuity.

Q: Do all substitute parts meet the same compliance standards?

A: Yes. All listed substitute parts are ROHS3 compliant, carry MSL Level 1 (Unlimited moisture sensitivity), and are REACH unaffected. Regulatory compliance is maintained across all substitutes.
