Key Parameters

Substitute Part Grouping Explanation

Substitution of the RCS3216J682CS is determined by strict adherence to the following electrical and mechanical parameters:

Primary Substitution Criteria:

• Resistance value: 6.8 kOhms (exact match required)
• Package / Case: 1206 (3216 Metric) (exact match required)
• Power rating: 0.25W minimum (equal or higher acceptable)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C minimum
• RoHS3 compliance required
• MSL 1 rating required

Tolerance Consideration: The RCS3216J682CS specifies ±5% tolerance. Substitute parts with ±1% tolerance (tighter specification) are electrically compatible and represent an upgrade path. Parts with ±5% tolerance provide direct equivalence.

Substitutes are grouped into two categories:

1. Direct Equivalents (±5% Tolerance): AC1206JR-076K8L, RC1206JR-076K8L
2. Enhanced Specification Substitutes (±1% Tolerance): AC1206FR-076K8L, CR1206-FX-6801ELF, CRCW12066K80FKEA, ERJ-8ENF6801V, RC1206FR-076K8L
3. Higher Power Rating Substitute (0.75W): CRCW12066K80FKEAHP

All listed substitutes maintain identical resistance, package, composition, temperature coefficient, and operating temperature range. Dimensional variations are within acceptable mechanical tolerances for 1206 package footprints.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Identical Specifications): Select AC1206JR-076K8L or RC1206JR-076K8L when ±5% tolerance and 0.25W power rating are required. Both parts are in active production status with high inventory availability (9,936 and 90,018 units respectively). YAGEO parts offer automotive AEC-Q200 qualification, providing enhanced reliability for demanding applications.

For Enhanced Tolerance Applications: AC1206FR-076K8L, CR1206-FX-6801ELF, CRCW12066K80FKEA, RC1206FR-076K8L, and ERJ-8ENF6801V provide ±1% tolerance while maintaining all other electrical and mechanical parameters. These parts are suitable when circuit design requires tighter resistance tolerance. All are ROHS3 compliant with MSL 1 rating. AC1206FR-076K8L, CRCW12066K80FKEA, and ERJ-8ENF6801V carry automotive AEC-Q200 certification.

For Higher Power Dissipation: CRCW12066K80FKEAHP provides 0.75W (3/4W) power rating in the same 1206 package footprint. This part is suitable for applications requiring increased thermal headroom while maintaining identical resistance and tolerance specifications. Automotive AEC-Q200 and pulse withstanding features are included.

Product Status Consideration: ERJ-8ENF6801V carries "Not For New Designs" status. While electrically and mechanically compatible, this part should be used only for legacy system maintenance or repair applications. For new designs, select from active production parts: AC1206JR-076K8L, AC1206FR-076K8L, CR1206-FX-6801ELF, CRCW12066K80FKEA, CRCW12066K80FKEAHP, RC1206JR-076K8L, or RC1206FR-076K8L.

Compliance and Certification: All substitute parts maintain ROHS3 compliance and MSL 1 rating. Parts with automotive AEC-Q200 certification (AC1206FR-076K8L, AC1206JR-076K8L, CRCW12066K80FKEA, CRCW12066K80FKEAHP, ERJ-8ENF6801V) are qualified for automotive and industrial applications requiring enhanced reliability standards.

Frequently Asked Questions (FAQ)

Q: Can AC1206FR-076K8L (±1% tolerance) be used as a direct replacement for RCS3216J682CS (±5% tolerance)?

A: Yes. The ±1% tolerance specification is tighter than ±5%, representing an upgrade in accuracy. The part is electrically and mechanically compatible. All other parameters—resistance value, power rating, package, temperature coefficient, and operating temperature range—are identical. ROHS3 compliance and MSL 1 rating are maintained.

Q: What is the difference between AC1206JR-076K8L and RC1206JR-076K8L?

A: Both parts are manufactured by YAGEO with identical electrical specifications: 6.8 kOhms ±5%, 0.25W, 1206 package. AC1206JR-076K8L carries automotive AEC-Q200 certification, while RC1206JR-076K8L does not. RC1206JR-076K8L has significantly higher inventory (90,018 units vs. 9,936 units). Selection depends on application requirements and availability constraints.

Q: Can CRCW12066K80FKEAHP (0.75W) be used in place of RCS3216J682CS (0.25W)?

A: Yes. The 0.75W power rating is higher than the 0.25W requirement, providing additional thermal margin. The part maintains identical resistance, tolerance (±1%), package (1206), temperature coefficient, and operating temperature range. This substitution is suitable when increased power dissipation capability is beneficial or required by circuit design.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity level, matching the original RCS3216J682CS specification.

Q: Why is ERJ-8ENF6801V marked "Not For New Designs"?

A: ERJ-8ENF6801V carries this status from Panasonic Electronic Components, indicating the manufacturer is phasing out this part number. While electrically and mechanically compatible, it should be used only for maintenance, repair, or legacy system support. For new designs, select from active production alternatives such as AC1206JR-076K8L, CR1206-FX-6801ELF, CRCW12066K80FKEA, or RC1206JR-076K8L.

Q: What is the significance of automotive AEC-Q200 certification?

A: AEC-Q200 is an automotive industry standard qualification for passive components. Parts carrying this certification (AC1206FR-076K8L, AC1206JR-076K8L, CRCW12066K80FKEA, CRCW12066K80FKEAHP, ERJ-8ENF6801V) have undergone enhanced reliability testing and are suitable for automotive, industrial, and mission-critical applications. Non-certified parts (CR1206-FX-6801ELF, RC1206FR-076K8L, RC1206JR-076K8L) are suitable for general-purpose applications.

Q: Do dimensional variations between substitute parts affect PCB layout?

A: All substitute parts use the 1206 (3216 Metric) package with standardized footprint dimensions. Dimensional variations (length 3.10mm to 3.20mm, height 0.60mm to 0.75mm) are within acceptable mechanical tolerances for standard 1206 land patterns. PCB layout modifications are not required.

Q: Which substitute part offers the best inventory availability?

A: RC1206FR-076K8L provides the highest inventory with 133,607 units in stock, followed by RC1206JR-076K8L with 90,018 units. Both are YAGEO products in active production status. For immediate availability with enhanced specifications, CRCW12066K80FKEA (Vishay Dale, 14,523 units) offers ±1% tolerance and automotive AEC-Q200 certification.
