RC3216F244CS Equivalent & Substitute Parts Reference

Part Overview

The RC3216F244CS is a 240 kOhms ±1% 0.25W thick film chip resistor manufactured by Samsung Electro-Mechanics in 1206 (3216 Metric) package format. This component is classified as Active product status with moisture-resistant construction and operates across the temperature range of -55°C to 155°C. The part is ROHS3 compliant and carries MSL Level 1 (Unlimited) moisture sensitivity rating.

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 performance characteristics. Substitute components enable design flexibility, supply chain optimization, and alternative sourcing when the primary part becomes unavailable.

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict equivalence across the following critical parameters:

Electrical Equivalence: Resistance value (240 kOhms), tolerance (±1%), and power dissipation rating (0.25W) must match exactly. Temperature coefficient (±100ppm/°C) and operating temperature range (-55°C ~ 155°C) establish thermal performance boundaries.

Mechanical Compatibility: Package designation (1206 / 3216 Metric) ensures physical fit and PCB footprint alignment. Component dimensions and height specifications must accommodate existing board layouts and assembly processes.

Environmental & Compliance Standards: All substitute parts maintain ROHS3 compliance, MSL Level 1 rating, and REACH unaffected status. Composition (thick film) and termination count (2) remain constant across all qualified substitutes.

Product Status Consideration: Active status parts are preferred for new designs. Parts marked "Not For New Designs" or "Discontinued" are listed for reference in legacy system support or existing inventory utilization only.

Engineering Selection Recommendations

For Active Product Designs: Select from parts with Active product status: CR1206-FX-2403ELF (Bourns), RC1206FR-07240KL (YAGEO), RMCF1206FT240K (Stackpole), CRCW1206240KFKEA (Vishay Dale), or KTR18EZPF2403 (Rohm). These components are qualified for new design implementations and carry full manufacturer support.

For Automotive Applications: Parts bearing AEC-Q200 certification (RMCF1206FT240K, CRCW1206240KFKEA, KTR18EZPF2403, ERJ-8ENF2403V) meet automotive-grade reliability and qualification standards. KTR18EZPF2403 additionally incorporates high-voltage performance characteristics.

For General Industrial Applications: CR1206-FX-2403ELF and RC1206FR-07240KL provide moisture-resistant construction suitable for standard industrial environments with Active product status and established supply availability.

For Legacy System Support: ERJ-8ENF2403V and MCR18ERTF2403 are available for maintenance and repair of existing systems, though both carry product status limitations (Not For New Designs and Discontinued respectively).

Packaging Considerations: Tape & Reel packaging is standard for high-volume production. Cut Tape & Digi-Reel options (RC1206FR-07240KL, MCR18ERTF2403) accommodate lower-volume or prototype applications.

Frequently Asked Questions (FAQ)

Q: What determines if a part can substitute for RC3216F244CS?

A: Substitution requires exact matching of resistance value (240 kOhms), tolerance (±1%), power rating (0.25W), package format (1206), temperature coefficient (±100ppm/°C), and operating temperature range (-55°C ~ 155°C). All substitute parts must maintain ROHS3 compliance and MSL Level 1 rating.

Q: Can I use ERJ-8ENF2403V in a new design?

A: No. ERJ-8ENF2403V carries "Not For New Designs" product status. This part is available for legacy system support and existing inventory utilization only. Use Active status alternatives for new design implementations.

Q: What is the difference between moisture-resistant and automotive AEC-Q200 variants?

A: Moisture-resistant variants (CR1206-FX-2403ELF, RC1206FR-07240KL) are optimized for standard industrial environments. Automotive AEC-Q200 variants (RMCF1206FT240K, CRCW1206240KFKEA, KTR18EZPF2403) meet automotive qualification standards and reliability requirements. Both meet the same electrical and thermal specifications.

Q: Does packaging type affect electrical performance?

A: No. Tape & Reel and Cut Tape & Digi-Reel packaging types do not affect electrical performance. Packaging selection is based on production volume, assembly process, and inventory management requirements.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts maintain ROHS3 compliance and REACH unaffected status, matching the environmental compliance profile of RC3216F244CS.

Q: What does MSL Level 1 (Unlimited) mean?

A: MSL Level 1 indicates unlimited shelf life without moisture bake-out requirements. The component can be stored indefinitely under normal conditions without special moisture control procedures.

Q: Can I interchange parts with different height specifications?

A: Height variations (0.024" to 0.030" seated maximum) are within standard 1206 package tolerances and do not prevent mechanical interchangeability on standard PCB layouts. Verify specific board design constraints if height-critical applications exist.

Q: Which substitute offers the highest inventory availability?

A: ERJ-8ENF2403V (Panasonic) shows 80,633 pieces in stock, followed by KTR18EZPF2403 (Rohm) with 54,321 pieces. For Active status parts, CR1206-FX-2403ELF (Bourns) provides 29,737 pieces.
