Substitute Part Grouping Explanation

Substitution eligibility for the RCS3216F11R3CS is determined by strict alignment of the following parameters:

Critical Matching Parameters:

Resistance value: 11.3 Ohms
Tolerance: ±1%
Power rating: 0.25W (1/4W)
Package: 1206 (3216 Metric)
Composition: Thick Film
Temperature coefficient: ±100ppm/°C
Operating temperature range: -55°C ~ 155°C
RoHS3 compliance
MSL rating: 1 (Unlimited)

All identified substitute parts meet these electrical and mechanical specifications. Variations in physical dimensions (length, width, height) remain within acceptable tolerances for 1206 package classification. Differences in manufacturer-specific features (such as automotive AEC-Q200 certification for certain substitutes) represent additional capabilities that do not prevent functional equivalence.

Engineering Selection Recommendations

Primary Selection (Active Status): CRCW120611R3FKEA (Vishay Dale) and RC1206FR-0711R3L (YAGEO) are both classified as Active products with full RoHS3 compliance and unlimited MSL rating. These components are suitable for new designs and ongoing production applications. CRCW120611R3FKEA includes automotive AEC-Q200 certification, providing additional qualification for automotive circuit applications.

Secondary Selection (Legacy Status): ERJ-8ENF11R3V (Panasonic Electronic Components) is classified as Not For New Designs. This component maintains full electrical and mechanical equivalence with identical resistance, tolerance, power rating, and temperature specifications. Use of this part is restricted to replacement or maintenance of existing assemblies where original component sourcing is unavailable.

Compliance Alignment: All substitute parts maintain ROHS3 compliance and MSL 1 (Unlimited) rating, ensuring compatibility with moisture-sensitive device handling requirements and environmental regulations. No additional qualification or testing is required for direct substitution based on provided compliance certifications.

Frequently Asked Questions (FAQ)

Q: Can CRCW120611R3FKEA directly replace RCS3216F11R3CS in existing designs?

A: Yes. Both components share identical electrical specifications (11.3 Ohms ±1%, 0.25W), temperature coefficient (±100ppm/°C), operating range (-55°C ~ 155°C), and package classification (1206). Physical dimensions are equivalent within 1206 package tolerances. RoHS3 and MSL ratings are identical.

Q: What is the difference between the substitute parts?

A: All three substitute parts (CRCW120611R3FKEA, ERJ-8ENF11R3V, RC1206FR-0711R3L) meet the core electrical and mechanical requirements. CRCW120611R3FKEA includes automotive AEC-Q200 certification. ERJ-8ENF11R3V carries Not For New Designs status. RC1206FR-0711R3L is Active status. Physical height varies slightly (0.024" to 0.028" maximum seated height), remaining within 1206 package specifications.

Q: Is the slight dimension variation in RC1206FR-0711R3L (3.10mm length vs. 3.20mm) a concern?

A: No. Both dimensions fall within the 1206 (3216 Metric) package classification tolerance band. PCB footprint design for 1206 packages accommodates this variation. Component placement and soldering are unaffected.

Q: Can ERJ-8ENF11R3V be used in new product designs?

A: No. ERJ-8ENF11R3V is classified as Not For New Designs. This designation restricts its use to replacement of existing assemblies. For new designs, select CRCW120611R3FKEA or RC1206FR-0711R3L, both carrying Active product status.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All identified substitute parts carry ROHS3 Compliant status and MSL 1 (Unlimited) rating, matching the original RCS3216F11R3CS specifications.
