Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RC1608F5113CS are classified into two categories based on electrical and mechanical parameter alignment:

Direct Substitutes maintain identical specifications across all critical parameters: 511 kOhms resistance, ±1% tolerance, 0.1W power rating, 0603 package, thick film composition, ±100ppm/°C temperature coefficient, -55°C to 155°C operating range, and ROHS3 compliance. These parts are interchangeable without design modification.

Similar Substitutes meet all core electrical and mechanical requirements but include additional features such as Automotive AEC-Q200 qualification. These parts are suitable for applications where the additional certification does not create conflicts with existing design specifications or procurement requirements.

Substitution eligibility is determined by the following parameters:

• Resistance value: 511 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: -55°C to 155°C (exact match required)
• RoHS compliance: ROHS3 (minimum requirement)

Parameter Comparison

Engineering Selection Recommendations

Direct Substitutes (CR0603-FX-5113ELF, RC0603FR-07511KL) are recommended for applications where component specifications must remain identical to the original design. Both parts maintain all electrical and mechanical parameters without additional certifications, ensuring seamless integration into existing circuit designs and manufacturing processes.

Similar Substitutes (AC0603FR-07511KL, CRCW0603511KFKEA, ERJ-3EKF5113V, RMCF0603FT511K) include Automotive AEC-Q200 qualification and are suitable for applications where automotive-grade reliability is required or where design specifications permit enhanced component qualification. These parts meet all core requirements of the RC1608F5113CS while providing additional compliance documentation.

Selection between direct and similar substitutes depends on application requirements and procurement specifications. All listed substitutes maintain ROHS3 compliance and MSL 1 rating, ensuring compatibility with standard surface mount assembly processes and storage conditions.

Frequently Asked Questions (FAQ)

Q: Can CR0603-FX-5113ELF replace RC1608F5113CS in any application?

A: CR0603-FX-5113ELF is a direct substitute meeting all electrical and mechanical specifications of RC1608F5113CS. Both components share identical resistance (511 kOhms), tolerance (±1%), power rating (0.1W), package (0603), composition (thick film), temperature coefficient (±100ppm/°C), and operating temperature range (-55°C to 155°C). Substitution is valid without design modification.

Q: What is the difference between direct and similar substitutes?

A: Direct substitutes (CR0603-FX-5113ELF, RC0603FR-07511KL) match all specifications of the main part without additional features. Similar substitutes (AC0603FR-07511KL, CRCW0603511KFKEA, ERJ-3EKF5113V, RMCF0603FT511K) include Automotive AEC-Q200 qualification in addition to meeting all core electrical and mechanical requirements. Selection depends on whether automotive-grade certification is required for the application.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts are ROHS3 compliant, matching the compliance status of the RC1608F5113CS. All parts also maintain MSL 1 (Unlimited) moisture sensitivity rating.

Q: Can I use an AEC-Q200 qualified resistor in a non-automotive application?

A: Yes. AEC-Q200 qualified parts (AC0603FR-07511KL, CRCW0603511KFKEA, ERJ-3EKF5113V, RMCF0603FT511K) meet or exceed the specifications required for non-automotive applications. The additional automotive qualification does not create incompatibility with standard industrial or consumer applications.

Q: Are there physical dimension differences between substitute parts?

A: Substitute parts maintain the 0603 (1608 Metric) package designation. Minor dimensional variations exist within standard tolerances: most parts measure 0.063" L x 0.031" W (1.60mm x 0.80mm) with height 0.022" (0.55mm); CRCW0603511KFKEA measures 0.061" L x 0.033" W (1.55mm x 0.85mm) with height 0.020" (0.50mm); RMCF0603FT511K measures 0.061" L x 0.031" W (1.55mm x 0.80mm) with height 0.022" (0.55mm). These variations remain within standard PCB footprint tolerances for 0603 packages.

Q: What inventory levels are available for substitute parts?

A: Current inventory: CR0603-FX-5113ELF (62,713 pcs), RC0603FR-07511KL (404,982 pcs), AC0603FR-07511KL (5,265 pcs), CRCW0603511KFKEA (42,781 pcs), ERJ-3EKF5113V (58,786 pcs), RMCF0603FT511K (33,952 pcs). Inventory levels are subject to change based on supply and demand conditions.
