RC3216J682CS 6.8kΩ 1206 Chip Resistor Equivalent & Substitute Parts

Part Overview

The RC3216J682CS is a 6.8 kΩ ±5% 0.25W thick film chip resistor in 1206 (3216 metric) package manufactured by Samsung Electro-Mechanics. This component is classified as Active product status with ROHS3 compliance and unlimited moisture sensitivity level (MSL 1). The part is suitable for general-purpose applications requiring moisture-resistant thick film construction across the operating temperature range of -55°C to 155°C.

Equivalent and substitute parts are identified based on matching electrical specifications (resistance value, tolerance, power rating), mechanical compatibility (package size and form factor), and environmental ratings. Direct equivalents maintain identical tolerance and features, while upgrade substitutes offer improved tolerance or additional certifications such as automotive AEC-Q200 qualification.

Substitute Part Grouping Explanation

Substitute parts for the RC3216J682CS are categorized into two groups based on substitution compatibility:

Direct Equivalent (Same Tolerance):

RC1206JR-076K8L (YAGEO) maintains identical electrical specifications: 6.8 kΩ ±5% tolerance, 0.25W power rating, thick film composition, and identical operating temperature range. Physical dimensions are within acceptable tolerance for 1206 package footprint compatibility.

Upgrade Substitutes (Improved Tolerance ±1%):

AC1206FR-076K8L, CR1206-FX-6801ELF, CRG1206F6K8, ERJ-8ENF6801V, KTR18EZPF6801, RC1206FR-076K8L, and RMCF1206FT6K80 all provide tighter tolerance specification (±1% versus ±5%), maintaining identical resistance value, power rating, package form factor, and operating temperature range. These parts are suitable for applications requiring improved accuracy without functional circuit changes.

Similar Parts (Same Tolerance, Different Features):

AC1206JR-076K8L (YAGEO) and CRCW12066K80FKEA (Vishay Dale) maintain ±5% tolerance matching the main part but introduce automotive AEC-Q200 certification, suitable for automotive applications where the original part may not be specified.

Substitution logic is based strictly on: resistance value (6.8 kΩ), power rating (0.25W), package type (1206), composition (thick film), temperature coefficient (±100ppm/°C), operating temperature range (-55°C to 155°C), and compliance certifications (ROHS3, MSL 1).

Frequently Asked Questions (FAQ)

Q: Can RC1206JR-076K8L directly replace RC3216J682CS without circuit modification?

A: Yes. RC1206JR-076K8L is a direct equivalent maintaining identical electrical specifications (6.8 kΩ ±5%, 0.25W), thick film composition, operating temperature range (-55°C to 155°C), and 1206 package footprint. No circuit redesign or tolerance stack analysis is required.

Q: What is the difference between the main part and upgrade substitutes with ±1% tolerance?

A: Upgrade substitutes (RC1206FR-076K8L, AC1206FR-076K8L, CR1206-FX-6801ELF, and others) provide tighter tolerance specification (±1% versus ±5%). All other parameters—resistance value, power rating, package type, temperature coefficient, and operating temperature range—remain identical. The ±1% tolerance improves circuit accuracy without functional changes.

Q: Are automotive AEC-Q200 parts interchangeable with the standard RC3216J682CS?

A: Electrically and mechanically, yes. Parts such as AC1206FR-076K8L, RMCF1206FT6K80, and CRCW12066K80FKEA are fully compatible with RC3216J682CS in terms of resistance, power rating, package, and operating temperature. However, AEC-Q200 certification introduces additional qualification requirements specific to automotive applications. Use AEC-Q200 parts only when automotive specifications are required by circuit design or system standards.

Q: What does "Not For New Designs" status mean for ERJ-8ENF6801V?

A: This designation indicates the manufacturer (Panasonic) is discontinuing the part. While ERJ-8ENF6801V meets all electrical and mechanical specifications, it should not be selected for new product development. Use only for legacy system maintenance or repair where existing inventory exists.

Q: Are there physical dimension differences between substitute parts?

A: All substitute parts conform to 1206 (3216 metric) package specification. Minor variations exist within tolerance: length ranges from 0.122" to 0.126" (3.10mm to 3.20mm), width is consistently 0.063" (1.60mm), and height ranges from 0.024" to 0.030" (0.60mm to 0.75mm). These variations are within standard PCB footprint tolerance and do not affect assembly or functionality.

Q: Which substitute part offers the best combination of availability and specifications?

A: RC1206FR-076K8L (YAGEO) combines high inventory availability (133,607 pcs), ±1% tolerance upgrade, Active product status, moisture-resistant features, and ROHS3 compliance. CRG1206F6K8 (TE Connectivity) and RMCF1206FT6K80 (Stackpole) also provide strong availability with automotive AEC-Q200 certification for applications requiring that qualification.

Q: Can I use a ±1% tolerance part in a circuit designed for ±5% tolerance?

A: Yes. A ±1% tolerance part is a superior substitute for a ±5% specification. The tighter tolerance provides better accuracy and does not introduce incompatibility. No circuit redesign is required; the ±1% part will perform within the original ±5% tolerance window.

Q: What is the significance of Moisture Sensitivity Level (MSL) 1?

A: MSL 1 indicates unlimited shelf life without moisture bake-out requirements. Both the main part (RC3216J682CS) and all substitute parts carry MSL 1 classification, meaning they can be stored indefinitely without special humidity control or pre-reflow baking procedures.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. The main part RC3216J682CS and all listed substitute parts are ROHS3 compliant. This compliance is consistent across all alternatives and does not differentiate substitution suitability.
