Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RC3216J6R8CS are classified into two functional groups based on tolerance specification:

Group 1: Direct Tolerance Match (±5%) Parts maintaining the original ±5% tolerance specification. These substitutes provide identical electrical performance characteristics and are interchangeable without circuit redesign consideration.

Group 2: Upgraded Tolerance (±1%) Parts with improved ±1% tolerance specification. These substitutes offer tighter resistance accuracy while maintaining all other electrical and mechanical parameters. Substitution from ±5% to ±1% tolerance represents an upgrade path and does not require circuit modification.

Substitution Criteria (Mandatory Parameters):

• Resistance value: 6.8 Ohms (exact match required)
• Power rating: 0.25W minimum
• Package: 1206 (3216 Metric) form factor
• Composition: Thick Film technology
• Operating temperature range: -55°C to 155°C minimum
• RoHS3 compliance
• MSL 1 classification

All substitute parts listed meet these criteria. Tolerance upgrades (±5% to ±1%) are permitted substitutions. Tolerance downgrades are not applicable in this reference.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Same Tolerance ±5%): RC1206JR-076R8L (YAGEO) is the equivalent substitute maintaining ±5% tolerance specification. This part is Active product status with ROHS3 compliance and MSL 1 classification, identical to the main part. Selection is appropriate when tolerance specification must remain unchanged and inventory availability is a consideration.

For Tolerance Upgrade (±1% Tolerance): Four substitute options provide ±1% tolerance upgrade:

1. RC3216F6R8CS (Samsung Electro-Mechanics) – Same manufacturer as main part, ensuring design continuity. Maintains identical feature set (Moisture Resistant) and temperature coefficient specification. Recommended for designs requiring tighter tolerance without introducing new supplier dependencies.

2. RC1206FR-076R8L (YAGEO) – Standard industrial-grade ±1% resistor with Moisture Resistant features. Suitable for general commercial applications requiring improved accuracy.

3. ERJ-8RQF6R8V (Panasonic Electronic Components) – AEC-Q200 automotive-qualified component with Current Sense feature. Temperature coefficient ±200ppm/°C. Selection appropriate for automotive applications or designs requiring automotive-grade reliability.

4. KTR18EZPF6R80 (Rohm Semiconductor) – AEC-Q200 automotive-qualified component with High Voltage feature and superior temperature coefficient (±100ppm/°C). Selection appropriate for high-reliability automotive applications or circuits with stringent temperature stability requirements.

5. RMCF1206FT6R80 (Stackpole Electronics Inc) – AEC-Q200 automotive-qualified component with highest inventory availability (58,092 pcs). Temperature coefficient ±200ppm/°C. Selection appropriate for high-volume production or automotive applications prioritizing supply chain security.

All substitute parts maintain ROHS3 compliance, MSL 1 classification, and -55°C to 155°C operating temperature range. Selection between options depends on application requirements (automotive vs. commercial), temperature stability needs, and supply chain strategy.

Frequently Asked Questions (FAQ)

Q1: Can RC3216J6R8CS be replaced with a ±1% tolerance part?

A: Yes. Tolerance upgrade from ±5% to ±1% is a valid substitution. All ±1% alternatives listed (RC3216F6R8CS, RC1206FR-076R8L, ERJ-8RQF6R8V, KTR18EZPF6R80, RMCF1206FT6R80) meet or exceed the electrical and mechanical specifications of the original part. Circuit redesign is not required.

Q2: Are all substitute parts physically compatible with the 1206 package footprint?

A: Yes. All substitute parts are specified as 1206 (3216 Metric) package. Physical dimensions are within standard 1206 tolerances. Slight variations in length (0.122" to 0.126") and height (0.026" to 0.028") are within PCB assembly process capabilities and do not affect placement or soldering.

Q3: What is the difference between automotive-qualified (AEC-Q200) and standard industrial parts?

A: AEC-Q200 qualified parts (ERJ-8RQF6R8V, KTR18EZPF6R80, RMCF1206FT6R80) undergo additional qualification testing for automotive applications, including thermal cycling, humidity bias, and mechanical stress testing. Standard industrial parts (RC3216J6R8CS, RC3216F6R8CS, RC1206JR-076R8L, RC1206FR-076R8L) meet general commercial specifications. Selection depends on application environment and reliability requirements.

Q4: Which substitute offers the best temperature stability?

A: KTR18EZPF6R80 (Rohm Semiconductor) provides the lowest temperature coefficient at ±100ppm/°C, compared to ±200ppm/°C for most alternatives and ±300ppm/°C for the original part. This specification indicates superior resistance value stability across the -55°C to 155°C operating range. Selection is appropriate for precision analog circuits or temperature-sensitive applications.

Q5: Can the original RC3216J6R8CS be substituted with a lower tolerance part in reverse?

A: No. Tolerance downgrade from ±5% to a lower specification is not a valid substitution. All listed alternatives maintain ±5% or better (±1%) tolerance. Downgrade substitution would compromise circuit performance and is not supported.

Q6: Are all substitute parts ROHS3 compliant?

A: Yes. All substitute parts listed are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity level, matching the regulatory and handling requirements of the original RC3216J6R8CS.

Q7: Which substitute has the highest inventory availability?

A: RMCF1206FT6R80 (Stackpole Electronics Inc) has the highest inventory at 58,092 pieces. This part is recommended for high-volume production runs or applications requiring supply chain security.
