Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC1608F3013CS is determined by strict equivalence across the following critical parameters:

Electrical Parameters (Must Match Exactly):

• Resistance value: 301 kOhms
• Tolerance: ±1%
• Power rating: 0.1W
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C to +155°C

Mechanical Parameters (Must Match Exactly):

• Package type: 0603 (1608 Metric)
• Composition: Thick Film
• Number of terminations: 2
• Moisture Sensitivity Level: 1 (Unlimited)

Compliance Parameters:

• RoHS3 Compliant status
• REACH status alignment
• ECCN classification: EAR99

Substitute parts are classified into two categories:

Direct Substitutes: Parts meeting all electrical, mechanical, and compliance parameters with identical or equivalent physical dimensions and material composition. These parts are interchangeable without design modification.

Similar Substitutes: Parts meeting all electrical and mechanical parameters but with automotive-grade AEC-Q200 certification or minor dimensional variations within acceptable tolerances. These parts are suitable for applications where enhanced reliability or automotive qualification is beneficial or required.

Parameter Comparison

Engineering Selection Recommendations

Tier 1 - Direct Substitutes (Preferred for General Applications):

CR0603-FX-3013ELF (Bourns Inc.) and RC0603FR-07301KL (YAGEO) are direct functional equivalents to the RC1608F3013CS. Both parts maintain identical electrical specifications, package dimensions, and RoHS3 compliance without automotive qualification. These parts are suitable for standard industrial and commercial applications where AEC-Q200 certification is not required. CR0603-FX-3013ELF offers 44,474 units in stock, while RC0603FR-07301KL provides 314,913 units, ensuring supply availability.

Tier 2 - Automotive-Grade Substitutes (For Enhanced Reliability Requirements):

AC0603FR-07301KL (YAGEO), CRCW0603301KFKEA (Vishay Dale), ERJ-3EKF3013V (Panasonic Electronic Components), and RMCF0603FT301K (Stackpole Electronics Inc) are qualified to AEC-Q200 automotive standards while maintaining full electrical and mechanical equivalence. These parts are appropriate for applications requiring automotive-grade reliability, extended temperature cycling validation, or enhanced failure rate documentation. All four parts are Active status with adequate inventory levels.

Tier 3 - Avoid or Use with Caution:

CRCW0603301KFKEB (Vishay Dale) is discontinued at DiGi Electronics and should not be selected for new designs despite active inventory. CRCW0603301KFKTA (Vishay Dale) is RoHS non-compliant and REACH Affected, making it unsuitable for applications subject to environmental regulations or customer RoHS requirements.

Selection Logic:

For new designs and standard applications, select CR0603-FX-3013ELF or RC0603FR-07301KL based on supplier availability and lead time. For automotive applications or designs requiring AEC-Q200 qualification, select ERJ-3EKF3013V or RMCF0603FT301K. Verify final selection against specific design requirements for compliance certifications and supply chain constraints.

Frequently Asked Questions (FAQ)

Q: Can I use an AEC-Q200 qualified resistor in place of a non-qualified resistor?

A: Yes. AEC-Q200 qualified parts meet or exceed the electrical and mechanical specifications of non-qualified equivalents. Automotive-grade parts include additional validation for temperature cycling, moisture resistance, and failure rate documentation. Substituting a qualified part for a non-qualified part introduces no compatibility risk and may improve overall system reliability.

Q: What is the difference between CR0603-FX-3013ELF and RC0603FR-07301KL?

A: Both parts are direct substitutes with identical electrical specifications (301 kΩ, ±1%, 0.1W, 0603 package). The primary differences are manufacturer (Bourns vs. YAGEO) and inventory availability. CR0603-FX-3013ELF has 44,474 units in stock, while RC0603FR-07301KL has 314,913 units. Selection should be based on supplier preference and lead time requirements.

Q: Are all listed substitute parts RoHS3 compliant?

A: No. CRCW0603301KFKTA is RoHS non-compliant and REACH Affected. All other substitute parts listed are ROHS3 Compliant and REACH Unaffected. Verify RoHS compliance requirements for your application before final part selection.

Q: Can I use CRCW0603301KFKEB as a substitute?

A: CRCW0603301KFKEB is discontinued at DiGi Electronics and should not be selected for new designs. Although inventory exists (9,825 units), discontinued parts present long-term supply risk. Select active-status alternatives such as CRCW0603301KFKEA or ERJ-3EKF3013V instead.

Q: What does MSL 1 (Unlimited) mean for moisture sensitivity?

A: MSL 1 indicates the lowest moisture sensitivity level. These parts require no special moisture control during storage, handling, or assembly. No baking or desiccant storage is required before soldering, simplifying manufacturing logistics.

Q: Are there dimensional differences between substitute parts?

A: Minor dimensional variations exist within acceptable tolerances. The RC1608F3013CS, CR0603-FX-3013ELF, RC0603FR-07301KL, and ERJ-3EKF3013V share identical dimensions (0.063" L x 0.031" W, 0.022" max height). CRCW series parts (Vishay Dale) and RMCF0603FT301K have slightly different length and height specifications (0.061-0.063" L, 0.020-0.022" max height) but remain within 0603 package tolerance and are mechanically interchangeable on standard PCB layouts.

Q: Which substitute part has the highest inventory availability?

A: RC0603FR-07301KL (YAGEO) offers the highest inventory with 314,913 units in stock, followed by ERJ-3EKF3013V (Panasonic) with 67,636 units. For immediate availability, these two parts are recommended.

Q: Can I substitute a 301 kΩ resistor with a different tolerance grade?

A: No. Tolerance is a critical electrical parameter. The RC1608F3013CS specifies ±1% tolerance. Substitutes must maintain ±1% tolerance to ensure circuit performance and signal accuracy. Parts with different tolerance grades (such as ±5%) are not equivalent and will alter circuit behavior.
