Tolerance: ±1% (exact match required)
Power rating: 0.25W / 1/4W (exact match required)
Package: 1206 (3216 Metric) (exact match required)
Composition: Thick Film (exact match required)
Temperature coefficient: ±100ppm/°C (exact match required)
Operating temperature range: -55°C ~ 155°C (exact match required)

Engineering Selection Recommendations

Primary Substitutes (Active Status, Recommended for New Designs):

RC3216F2611CS (Samsung Electro-Mechanics) – Direct equivalent from the same manufacturer. Identical electrical and mechanical specifications with alternative packaging options (Cut Tape & Digi-Reel). Suitable for direct replacement in all applications.
CR1206-FX-2611ELF (Bourns Inc.) – Active production status with highest inventory availability (20,871 pcs). Meets all core substitution criteria. Suitable for general-purpose and industrial applications.
CRCW12062K61FKEA (Vishay Dale) – Active production status with automotive AEC-Q200 certification. Recommended for automotive and high-reliability applications requiring enhanced qualification standards. Inventory: 22,239 pcs.
AC1206FR-072K61L (YAGEO) – Active production status with automotive AEC-Q200 certification. Recommended for automotive applications. Highest inventory availability (7,132 pcs) among automotive-qualified options.
RC1206FR-072K61L (YAGEO) – Active production status. Meets all core specifications. Inventory: 27,053 pcs. Suitable for general-purpose applications.

Secondary Substitute (Not Recommended for New Designs):

ERJ-8ENF2611V (Panasonic Electronic Components) – Meets all core electrical and mechanical specifications with automotive AEC-Q200 certification. However, product status is "Not For New Designs." Use only for legacy system maintenance or replacement applications where continuity with existing designs is required.

Selection Logic:

For new designs requiring standard specifications: Select from CR1206-FX-2611ELF, RC1206FR-072K61L, or RC3216F2611CS based on packaging preference and supplier availability.
For automotive applications: Select CRCW12062K61FKEA or AC1206FR-072K61L for AEC-Q200 compliance.
For legacy system support: ERJ-8ENF2611V remains functionally equivalent but should not be specified for new designs.

Frequently Asked Questions (FAQ)

Q1: Can I substitute the RCS3216F2611CS with any of the listed parts without circuit redesign?

A: Yes. All listed substitute parts meet identical electrical specifications (2.61 kΩ ±1%, 0.25W) and mechanical requirements (1206 package, -55°C to 155°C operating range). Direct substitution is possible without circuit modification. Verify PCB footprint compatibility, as dimensional tolerances may vary slightly between manufacturers (see Height - Seated specifications in detailed datasheets).

Q2: What is the difference between the RCS3216F2611CS and RC3216F2611CS?

A: Both are Samsung Electro-Mechanics products with identical electrical and mechanical specifications. The primary difference is packaging: RCS3216F2611CS uses standard packaging, while RC3216F2611CS offers Cut Tape (CT) and Digi-Reel® options. Electrical performance is equivalent.

Q3: Are automotive-grade parts (AEC-Q200) required for my application?

A: Automotive AEC-Q200 certification is required only for applications subject to automotive industry standards or high-reliability requirements. For general industrial and consumer applications, non-automotive-qualified parts (CR1206-FX-2611ELF, RC1206FR-072K61L, RC3216F2611CS) are functionally equivalent and appropriate.

Q4: Why is ERJ-8ENF2611V marked "Not For New Designs"?

A: This designation indicates that Panasonic has discontinued active development and recommends alternative parts for new product designs. The part remains functionally equivalent and suitable for legacy system maintenance or replacement, but should not be specified in new designs due to potential future availability constraints.

Q5: How do I verify package compatibility before substitution?

A: All substitute parts use the 1206 (3216 Metric) package with identical footprint dimensions (0.126" L x 0.063" W / 3.20mm x 1.60mm). However, height specifications vary slightly (0.024" to 0.030" seated height). Verify that your PCB design accommodates the maximum height of the selected substitute part. Consult manufacturer datasheets for precise dimensional specifications.

Q6: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts carry ROHS3 compliance certification, meeting environmental and hazardous substance restrictions. All parts also maintain MSL 1 (Unlimited) moisture sensitivity level, indicating no special moisture handling requirements during storage or assembly.

Q7: Can I mix different manufacturers' parts in the same circuit board?

A: Yes. All substitute parts meet identical electrical and mechanical specifications. Mixing manufacturers is acceptable from a functional standpoint. However, for manufacturing consistency and supply chain management, it is recommended to standardize on a single manufacturer per design revision.
