Substitute Part Grouping Explanation
Substitution eligibility for the RC1608F2372CS is determined by strict equivalence across the following critical parameters:
Electrical Parameters (Must Match Exactly):
- Resistance value: 23.7 kOhms
- Tolerance: ±1%
- Power rating: 0.1W (1/10W)
- Temperature coefficient: ±100ppm/°C
- Operating temperature range: -55°C to 155°C
Mechanical Parameters (Must Match Exactly):
- Package type: 0603 (1608 Metric)
- Number of terminations: 2
- Composition: Thick Film
Compliance Parameters (Must Match or Exceed):
- RoHS Status: ROHS3 Compliant
- Moisture Sensitivity Level: 1 (Unlimited)
- REACH Status: REACH Unaffected
All substitute parts listed below satisfy these criteria. Additional qualifications such as AEC-Q200 automotive rating represent enhanced specifications that do not prevent substitution in non-automotive applications.

Engineering Selection Recommendations
All substitute parts listed are functionally equivalent to the RC1608F2372CS and are qualified for direct substitution based on matching electrical and mechanical specifications. Selection among available substitutes should be based on the following factors:
Product Status: All parts maintain Active product status, ensuring continued availability and manufacturer support.
Compliance Certifications: All substitute parts are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements equivalent to the primary part.
Automotive Qualification: Parts designated with AEC-Q200 rating (AC0603FR-0723K7L, CRCW060323K7FKEA, ERJ-3EKF2372V, RMCF0603FT23K7) include automotive-grade qualification. These parts are suitable for both automotive and general industrial applications. Non-automotive qualified parts (CR0603-FX-2372ELF, RC0603FR-0723K7L) are suitable for general industrial and consumer applications.
Packaging Format: Tape & Reel (TR) packaging is standard for high-volume automated assembly. Cut Tape (CT) & Digi-Reel® packaging offers flexibility for lower-volume or mixed-component orders.
Inventory Availability: RMCF0603FT23K7 (Stackpole) offers the highest inventory level at 175,235 pieces, followed by RC0603FR-0723K7L (YAGEO) at 123,495 pieces.
Frequently Asked Questions (FAQ)
Q: Can I substitute RC1608F2372CS with any of the listed parts without circuit redesign?
A: Yes. All listed substitute parts maintain identical electrical specifications (23.7 kOhms ±1%, 0.1W, ±100ppm/°C, -55°C to 155°C operating range) and mechanical compatibility (0603 package, 2 terminations, thick film composition). Direct substitution is permissible without circuit modification.
Q: What is the difference between parts with and without AEC-Q200 rating?
A: AEC-Q200 is an automotive industry qualification standard. Parts with AEC-Q200 rating (AC0603FR-0723K7L, CRCW060323K7FKEA, ERJ-3EKF2372V, RMCF0603FT23K7) have undergone additional testing for automotive reliability. These parts are suitable for both automotive and non-automotive applications. Non-automotive qualified parts are suitable for general industrial and consumer applications only.
Q: Does packaging type (Tape & Reel vs. Cut Tape) affect electrical performance?
A: No. Packaging type affects only the physical delivery and handling format. Tape & Reel (TR) is optimized for high-volume automated assembly lines. Cut Tape (CT) & Digi-Reel® offers flexibility for lower-volume orders or mixed component sourcing. Electrical and mechanical specifications remain identical regardless of packaging format.
Q: Are all substitute parts ROHS3 compliant?
A: Yes. All substitute parts listed are ROHS3 compliant and REACH unaffected, meeting current environmental regulations equivalent to the primary RC1608F2372CS part.
Q: What does MSL 1 (Unlimited) moisture sensitivity mean?
A: MSL 1 indicates the lowest moisture sensitivity level. Parts with MSL 1 have unlimited shelf life and do not require special moisture-controlled storage or baking procedures prior to soldering. This specification is identical across all listed parts.
Q: Can I mix different manufacturer parts in the same production batch?
A: Yes. All substitute parts meet identical electrical and mechanical specifications. However, manufacturing process variations between suppliers may result in minor differences in physical appearance or performance characteristics within specification limits. Quality control procedures should verify incoming parts meet specification requirements.
Q: Which substitute part offers the best availability?
A: RMCF0603FT23K7 (Stackpole Electronics Inc) offers the highest inventory level at 175,235 pieces, followed by RC0603FR-0723K7L (YAGEO) at 123,495 pieces. Availability should be confirmed with your component supplier, as inventory levels change continuously.
