Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC1608F2612CS is determined by strict equivalence across the following critical parameters:

Primary Substitution Criteria:

• Resistance value: 26.1 kOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Power rating: 0.1W / 1/10W (exact match required)
• Package: 0603 (1608 Metric) (exact match required)
• Composition: Thick Film (exact match required)
• Temperature coefficient: ±100ppm/°C (exact match required)
• Operating temperature range: -55°C to 155°C (exact match required)
• RoHS compliance: ROHS3 Compliant (exact match required)
• MSL rating: 1 (Unlimited) (exact match required)

Secondary Considerations:

• Packaging format (Tape & Reel vs. Cut Tape & Digi-Reel)
• Automotive qualification (AEC-Q200 certification)
• Moisture resistance feature availability
• Inventory availability and product status

All substitute parts listed maintain identical electrical and thermal specifications. Variations in physical dimensions (length, width, height) within the 0603 package classification and differences in automotive qualification represent the only permissible deviations.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalents (Preferred for Drop-In Replacement):

CR0603-FX-2612ELF (Bourns Inc.) and RC0603FR-0726K1L (YAGEO) are direct functional equivalents with Active product status and identical electrical specifications. Both are available in Tape & Reel packaging and maintain full compatibility with the RC1608F2612CS across all critical parameters. Selection between these options should be based on inventory availability and established supplier relationships.

Automotive-Qualified Alternatives:

AC0603FR-0726K1L (YAGEO), CRCW060326K1FKEA (Vishay Dale), ERJ-3EKF2612V (Panasonic), and RMCF0603FT26K1 (Stackpole Electronics) incorporate AEC-Q200 automotive qualification in addition to meeting all electrical and thermal specifications of the RC1608F2612CS. These parts are suitable for applications requiring automotive-grade reliability and traceability. All four maintain Active product status with substantial inventory availability.

Discontinued Component Consideration:

MCR03ERTF2612 (Rohm Semiconductor) is listed as Discontinued at DiGi Electronics and should be avoided for new designs or long-term supply chain planning. This part remains electrically equivalent but presents supply risk.

Packaging Format Selection:

Tape & Reel packaging (CR0603-FX-2612ELF, RC0603FR-0726K1L, AC0603FR-0726K1L, CRCW060326K1FKEA, RMCF0603FT26K1) is standard for high-volume automated assembly. Cut Tape & Digi-Reel packaging (MCR03ERTF2612, ERJ-3EKF2612V) accommodates lower-volume or mixed-component requirements.

Frequently Asked Questions (FAQ)

Q: Can I substitute RC1608F2612CS with any of the listed equivalent parts without circuit redesign?

A: Yes. All listed substitute parts maintain identical resistance value (26.1 kOhms), tolerance (±1%), power rating (0.1W), package format (0603), composition (thick film), temperature coefficient (±100ppm/°C), operating temperature range (-55°C to 155°C), and RoHS compliance. Direct substitution is electrically and mechanically valid.

Q: What is the difference between the standard RC0603FR-0726K1L and the automotive-qualified AC0603FR-0726K1L?

A: Both parts are manufactured by YAGEO and share identical electrical specifications. The AC0603FR-0726K1L carries AEC-Q200 automotive qualification, indicating compliance with automotive reliability and testing standards. The AC variant is suitable for automotive applications; the RC variant is suitable for general industrial and consumer applications. Physical dimensions and electrical performance are equivalent.

Q: Why is MCR03ERTF2612 marked as discontinued?

A: MCR03ERTF2612 is discontinued at DiGi Electronics, indicating it is no longer actively stocked or supported through this distribution channel. While electrically equivalent, this part should not be selected for new designs or applications requiring long-term supply assurance. Alternative active parts should be prioritized.

Q: Does packaging format (Tape & Reel vs. Cut Tape & Digi-Reel) affect electrical performance?

A: No. Packaging format affects only handling, storage, and assembly logistics. Tape & Reel is optimized for high-volume automated pick-and-place assembly. Cut Tape & Digi-Reel accommodates lower-volume or mixed-component assembly. Electrical and thermal performance remains identical regardless of packaging format.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts, including the main part RC1608F2612CS, are ROHS3 compliant and REACH unaffected. Environmental compliance is uniform across all options.

Q: What inventory levels should I consider when selecting between equivalent parts?

A: CR0603FR-0726K1L (YAGEO) offers the highest inventory availability at 756,360 pieces. ERJ-3EKF2612V (Panasonic) provides 422,733 pieces. RMCF0603FT26K1 (Stackpole) offers 53,115 pieces. CR0603-FX-2612ELF (Bourns) provides 168,357 pieces. Inventory selection depends on project volume requirements and supply chain strategy.

Q: Can I use automotive-qualified parts (AEC-Q200) in non-automotive applications?

A: Yes. Automotive-qualified parts exceed the reliability and testing requirements of general industrial applications. Using AEC-Q200 parts in non-automotive circuits provides additional margin and reliability assurance without penalty.
