RC3216F6651CS Equivalent & Substitute Parts

Part Overview

The RC3216F6651CS is a 6.65 kOhms ±1% 0.25W chip resistor manufactured by Samsung Electro-Mechanics in the 1206 (3216 Metric) package. This thick film, moisture-resistant component operates across the temperature range of -55°C to 155°C and is classified as Active product status. The RC3216F6651CS serves as a standard general-purpose resistor for industrial and commercial applications where precision tolerance and moisture resistance are required. Equivalent and substitute parts are identified for applications requiring alternative sourcing, inventory management, or specific compliance certifications such as automotive AEC-Q200 qualification.

Substitute Part Grouping Explanation

Substitution of the RC3216F6651CS is determined by strict equivalence across the following critical parameters: resistance value (6.65 kOhms), tolerance (±1%), power rating (0.25W), package type (1206 / 3216 Metric), composition (thick film), temperature coefficient (±100ppm/°C), operating temperature range (-55°C ~ 155°C), and moisture sensitivity level (MSL 1). All identified substitute parts maintain these electrical and mechanical specifications without deviation.

Substitute parts are categorized into three groups based on additional qualifications:

Direct Substitutes maintain identical specifications to the RC3216F6651CS with general industrial compliance. These parts are suitable for direct replacement in non-automotive applications.

Upgrade Substitutes include automotive AEC-Q200 certification, providing enhanced reliability qualification for automotive and high-reliability applications while maintaining all base electrical parameters.

Similar Substitutes include automotive AEC-Q200 certification or represent legacy product lines (Not For New Designs status) that remain electrically and mechanically compatible but may have minor dimensional variations within acceptable tolerances.

Engineering Selection Recommendations

For General Industrial Applications: The CR1206-FX-6651ELF (Bourns Inc.) and RC1206FR-076K65L (YAGEO) are direct substitutes with Active product status and full ROHS3 compliance. Both parts maintain identical electrical specifications and are suitable for immediate replacement in non-automotive circuits.

For Automotive and High-Reliability Applications: The AC1206FR-076K65L (YAGEO) and CRCW12066K65FKEA (Vishay Dale) are recommended as upgrade substitutes. Both parts carry AEC-Q200 automotive qualification while maintaining all base electrical and mechanical parameters of the RC3216F6651CS. These parts are appropriate for automotive, industrial control, and mission-critical applications requiring enhanced reliability certification.

For Legacy System Maintenance: The ERJ-8ENF6651V (Panasonic Electronic Components) is electrically and mechanically equivalent with AEC-Q200 certification. However, this part carries "Not For New Designs" product status, indicating it is suitable only for sustaining production or repair of existing systems. New designs should not incorporate this part.

All substitute parts are ROHS3 compliant, MSL 1 rated, and operate across the identical temperature range (-55°C ~ 155°C) as the original RC3216F6651CS.

Frequently Asked Questions (FAQ)

Q: Can I use CR1206-FX-6651ELF as a direct replacement for RC3216F6651CS?

A: Yes. The CR1206-FX-6651ELF maintains identical electrical specifications (6.65 kOhms ±1%, 0.25W, ±100ppm/°C, -55°C ~ 155°C) and package type (1206). Both parts are Active status and ROHS3 compliant. The only difference is the manufacturer (Bourns Inc. versus Samsung Electro-Mechanics).

Q: What is the difference between RC1206FR-076K65L and AC1206FR-076K65L?

A: Both parts are manufactured by YAGEO and share identical electrical specifications and package type. The AC1206FR-076K65L includes automotive AEC-Q200 certification, making it suitable for automotive applications. The RC1206FR-076K65L is a general-purpose industrial grade part. Select AC1206FR-076K65L for automotive or high-reliability applications.

Q: Why is ERJ-8ENF6651V marked "Not For New Designs"?

A: The ERJ-8ENF6651V is electrically and mechanically equivalent to the RC3216F6651CS and carries AEC-Q200 certification. However, the "Not For New Designs" status indicates that Panasonic has discontinued active development of this product line. This part is suitable only for sustaining production or repair of existing systems. New circuit designs should use alternative active-status parts such as CR1206-FX-6651ELF, RC1206FR-076K65L, or the automotive-qualified AC1206FR-076K65L.

Q: Are there dimensional differences between substitute parts?

A: All substitute parts use the 1206 (3216 Metric) package with nominal dimensions of 0.126" L x 0.063" W (3.20mm x 1.60mm). Minor variations in seated height exist: RC3216F6651CS (0.66mm), CR1206-FX-6651ELF (0.75mm), RC1206FR-076K65L (0.65mm), AC1206FR-076K65L (0.65mm), CRCW12066K65FKEA (0.60mm), and ERJ-8ENF6651V (0.70mm). These variations remain within standard 1206 package tolerances and do not affect PCB layout or assembly compatibility.

Q: Which substitute part has the highest inventory availability?

A: ERJ-8ENF6651V has the highest inventory at 48,811 pieces. However, due to its "Not For New Designs" status, CR1206-FX-6651ELF (25,445 pieces) or RC1206FR-076K65L (22,848 pieces) are preferred for new applications. For automotive applications, CRCW12066K65FKEA offers 12,332 pieces with AEC-Q200 certification.

Q: Can I use CRCW12066K65FKEA in a non-automotive application?

A: Yes. The CRCW12066K65FKEA is electrically and mechanically equivalent to the RC3216F6651CS. The AEC-Q200 certification indicates enhanced reliability qualification but does not restrict use in non-automotive applications. This part is suitable for any application requiring 6.65 kOhms ±1% 0.25W 1206 resistors.

Q: Are all substitute parts moisture resistant?

A: The CR1206-FX-6651ELF, RC1206FR-076K65L, and AC1206FR-076K65L explicitly specify moisture-resistant thick film composition. The CRCW12066K65FKEA and ERJ-8ENF6651V do not explicitly state moisture resistance in their specifications but maintain identical MSL 1 (Unlimited) ratings as the RC3216F6651CS, indicating equivalent moisture handling capability.
