Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RC1608F3402CS are classified into two categories based on electrical and mechanical compatibility:

Direct Substitutes share identical electrical specifications, package dimensions, and environmental ratings without additional certifications:

• CR0603-FX-3402ELF (Bourns Inc.)
• RC0603FR-0734KL (YAGEO)

Similar Substitutes meet all core electrical and mechanical requirements but include additional automotive qualification (AEC-Q200) or minor dimensional variations within acceptable tolerances:

• AC0603FR-0734KL (YAGEO) — Automotive AEC-Q200 qualified
• CRCW060334K0FKEA (Vishay Dale) — Automotive AEC-Q200 qualified, minor dimensional variance
• ERJ-3EKF3402V (Panasonic Electronic Components) — Automotive AEC-Q200 qualified
• RMCF0603FT34K0 (Stackpole Electronics Inc) — Automotive AEC-Q200 qualified, minor dimensional variance

All substitutes maintain the following critical parameters:

• Resistance: 34 kOhms
• Tolerance: ±1%
• Power Rating: 0.1W (1/10W)
• Package: 0603 (1608 Metric)
• Composition: Thick Film
• Temperature Coefficient: ±100ppm/°C
• Operating Temperature: -55°C ~ 155°C
• Moisture Sensitivity Level: 1 (Unlimited)
• RoHS3 Compliance

Parameter Comparison

Engineering Selection Recommendations

For Standard Industrial Applications: The RC0603FR-0734KL (YAGEO) and CR0603-FX-3402ELF (Bourns Inc.) are direct functional equivalents to the RC1608F3402CS. Both maintain identical electrical performance, package compatibility, and RoHS3 compliance. Selection between these options is based on supplier availability and inventory levels.

For Automotive Applications: When AEC-Q200 automotive qualification is required, the following parts are suitable substitutes:

• AC0603FR-0734KL (YAGEO)
• CRCW060334K0FKEA (Vishay Dale)
• ERJ-3EKF3402V (Panasonic Electronic Components)
• RMCF0603FT34K0 (Stackpole Electronics Inc)

All automotive-qualified alternatives maintain the same electrical specifications and operating temperature range as the primary part. Minor dimensional variations exist within acceptable manufacturing tolerances and do not affect PCB assembly or circuit performance.

Compliance Considerations: All listed substitutes are RoHS3 compliant and carry Moisture Sensitivity Level 1 (unlimited shelf life), eliminating special storage or handling requirements. REACH status is unaffected across all alternatives.

Frequently Asked Questions (FAQ)

Q: Can CR0603-FX-3402ELF replace RC1608F3402CS in any application? A: Yes. CR0603-FX-3402ELF is a direct substitute with identical electrical specifications (34 kOhms ±1%, 0.1W), package dimensions (0603), temperature coefficient (±100ppm/°C), and operating range (-55°C ~ 155°C). Both are RoHS3 compliant with MSL 1.

Q: What is the difference between direct substitutes and similar substitutes? A: Direct substitutes (CR0603-FX-3402ELF, RC0603FR-0734KL) have no additional certifications beyond RoHS3 compliance. Similar substitutes include AEC-Q200 automotive qualification, which adds reliability testing and qualification requirements. Electrical and mechanical parameters remain identical.

Q: Are the dimensional differences between CRCW060334K0FKEA and RC1608F3402CS significant? A: No. CRCW060334K0FKEA measures 0.061" L x 0.033" W (1.55mm x 0.85mm) versus RC1608F3402CS at 0.063" L x 0.031" W (1.60mm x 0.80mm). These variations fall within standard 0603 package tolerances and do not affect PCB footprint compatibility or assembly.

Q: Can I use an AEC-Q200 qualified part in a non-automotive application? A: Yes. AEC-Q200 qualification represents additional testing and reliability assurance. Parts meeting automotive standards are fully compatible with standard industrial applications and offer enhanced reliability margins.

Q: What is Moisture Sensitivity Level 1? A: MSL 1 indicates unlimited shelf life with no special moisture control requirements during storage or handling. All listed substitutes carry MSL 1, eliminating the need for dry-pack storage or baking procedures.

Q: Are all substitutes available in Tape & Reel packaging? A: Yes. All listed substitute parts are supplied in Tape & Reel (TR) packaging, matching the primary part's standard surface mount assembly format.

Q: Does the temperature coefficient affect substitutability? A: No. All substitutes maintain ±100ppm/°C temperature coefficient, identical to RC1608F3402CS. This parameter is consistent across all alternatives and does not differentiate substitution suitability.
