Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RCS3216F1742CS are qualified based on the following critical parameters that determine functional interchangeability:

Electrical Parameters:

• Resistance value: 17.4 kOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Power rating: 0.25W / 1/4W (exact match required)
• Temperature coefficient: ±100ppm/°C (exact match required)
• Operating temperature range: -55°C ~ 155°C (exact match required)

Mechanical Parameters:

• Package type: 1206 (3216 Metric) (exact match required)
• Composition: Thick Film (exact match required)
• Number of terminations: 2 (exact match required)

Compliance Parameters:

• RoHS3 Compliant (required)
• Moisture Sensitivity Level: 1 (Unlimited) (required)
• REACH Unaffected status (required)

All four substitute parts meet these criteria. Variations in physical dimensions (length, width, height) and additional features (anti-sulfur coating, automotive AEC-Q200 certification) do not prevent substitution but may offer enhanced performance characteristics for specific applications.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection (Active Production Status):

The CR1206-FX-1742ELF (Bourns Inc.), CRCW120617K4FKEA (Vishay Dale), and RC1206FR-0717K4L (YAGEO) are all active production parts with full compliance certifications. These three parts are suitable for new designs and ongoing production applications. All three maintain identical electrical specifications and operating parameters to the RCS3216F1742CS.

Secondary Selection (Automotive-Qualified):

The CRCW120617K4FKEA (Vishay Dale) and ERJ-8ENF1742V (Panasonic) carry AEC-Q200 automotive qualification. These parts are appropriate for automotive and high-reliability applications requiring enhanced qualification documentation.

Legacy Consideration:

The ERJ-8ENF1742V (Panasonic) carries a "Not For New Designs" status. This part remains available with 90,008 pieces in stock inventory and is suitable for legacy system maintenance and repair applications only. New design implementations should utilize active production alternatives.

Compliance Verification:

All substitute parts are ROHS3 compliant, REACH unaffected, and carry MSL 1 (Unlimited) moisture sensitivity ratings, matching the original RCS3216F1742CS specifications.

Frequently Asked Questions (FAQ)

Q: Can I substitute the RCS3216F1742CS with any of these four parts in my existing circuit?

A: Yes. All four substitute parts match the critical electrical parameters (17.4 kOhms ±1%, 0.25W, ±100ppm/°C, -55°C to 155°C) and mechanical specifications (1206 package, thick film composition). Physical dimension variations (height ranging from 0.024" to 0.030") are within acceptable PCB assembly tolerances and do not affect electrical performance or circuit functionality.

Q: Which substitute should I use for new product designs?

A: For new designs, select from the three active production parts: CR1206-FX-1742ELF (Bourns), CRCW120617K4FKEA (Vishay Dale), or RC1206FR-0717K4L (YAGEO). Avoid ERJ-8ENF1742V (Panasonic) for new designs due to its "Not For New Designs" status.

Q: What is the difference between the Vishay Dale CRCW120617K4FKEA and other substitutes?

A: The CRCW120617K4FKEA includes AEC-Q200 automotive qualification and has the lowest seated height (0.024" / 0.60mm). This part is optimal for automotive applications or space-constrained PCB layouts. All other electrical and thermal specifications remain identical to other substitutes.

Q: Does the Samsung RCS3216F1742CS anti-sulfur feature affect substitution compatibility?

A: No. The anti-sulfur feature is an additional protective characteristic of the Samsung part but is not a requirement for functional substitution. All substitute parts provide moisture resistance and operate within identical electrical and temperature parameters. The anti-sulfur coating does not impact circuit performance or compatibility.

Q: Are there inventory considerations when selecting a substitute?

A: Yes. Current inventory levels vary: RCS3216F1742CS (1,038 pcs), CR1206-FX-1742ELF (25,927 pcs), CRCW120617K4FKEA (13,659 pcs), ERJ-8ENF1742V (90,008 pcs), and RC1206FR-0717K4L (19,220 pcs). For high-volume production, the Panasonic ERJ-8ENF1742V offers the largest available stock, though it is not recommended for new designs.

Q: Can I mix different substitute parts in the same production batch?

A: Yes. All substitute parts meet identical electrical specifications and compliance requirements. Mixing different manufacturers in the same circuit or production batch does not affect circuit performance. However, for traceability and quality control purposes, maintaining consistent part sourcing within a single production run is recommended.

Q: What is the significance of the MSL 1 (Unlimited) rating?

A: MSL 1 (Unlimited) indicates that the component has no moisture sensitivity limitations and requires no special handling, storage, or baking procedures prior to soldering. All parts in this comparison, including the original RCS3216F1742CS and all substitutes, carry this rating, ensuring identical moisture management requirements.
