Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC1608F3573CS is determined by strict alignment of the following parameters:

Primary Substitution Criteria:

• Resistance value: 357 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)
• Temperature coefficient: ±100ppm/°C (exact match required)
• Operating temperature range: -55°C ~ 155°C (exact match required)
• Composition: Thick Film (exact match required)
• RoHS compliance: ROHS3 Compliant (exact match required)
• MSL rating: 1 (Unlimited) (exact match required)

Secondary Compatibility Factors:

• Packaging format: Tape & Reel (TR)
• Termination count: 2
• Physical dimensions: 0.063" L x 0.031" W (1.60mm x 0.80mm) nominal
• Height seated maximum: 0.022" (0.55mm) nominal

All identified substitute parts meet these criteria. Parts designated as "Direct" substitutes maintain identical specifications across all parameters. Parts designated as "Similar" include additional automotive AEC-Q200 qualification, which represents an enhancement to the base specification without compromising compatibility.

Parameter Comparison

Engineering Selection Recommendations

Direct Substitutes (Identical Specifications):

CR0603-FX-3573ELF (Bourns Inc.) and RC0603FR-07357KL (YAGEO) are direct functional equivalents to the RC1608F3573CS. Both components maintain identical electrical parameters, thermal characteristics, and compliance certifications. Selection between these options is based on inventory availability and supply chain considerations.

Enhanced Substitutes (AEC-Q200 Automotive Qualified):

AC0603FR-07357KL (YAGEO), CRCW0603357KFKEA (Vishay Dale), ERJ-3EKF3573V (Panasonic Electronic Components), and RMCF0603FT357K (Stackpole Electronics Inc) are functionally equivalent with the addition of Automotive AEC-Q200 qualification. These parts meet all electrical and mechanical specifications of the original component while providing enhanced reliability documentation for automotive applications. These substitutes are suitable for any application requiring the RC1608F3573CS, including non-automotive designs.

Product Status and Compliance:

All identified substitute parts maintain Active product status and ROHS3 compliance, ensuring continued availability and regulatory alignment. MSL 1 (Unlimited) rating across all parts confirms compatibility with standard manufacturing and storage conditions.

Frequently Asked Questions (FAQ)

Q: Can AC0603FR-07357KL replace RC1608F3573CS in a non-automotive application?

A: Yes. AC0603FR-07357KL meets all electrical and mechanical specifications of RC1608F3573CS. The AEC-Q200 automotive qualification represents an additional certification that does not restrict use in non-automotive circuits. The component is fully compatible.

Q: What is the difference between "Direct" and "Similar" substitute classifications?

A: Direct substitutes (CR0603-FX-3573ELF, RC0603FR-07357KL) match the original part specification exactly. Similar substitutes include Automotive AEC-Q200 qualification, which is an enhancement providing additional reliability documentation. All electrical and mechanical parameters remain identical.

Q: Are there dimensional differences between substitute parts?

A: Nominal dimensions are 0.063" L x 0.031" W (1.60mm x 0.80mm) with maximum seated height of 0.022" (0.55mm). CRCW0603357KFKEA and RMCF0603FT357K show minor dimensional variations (0.061" L x 0.033" W and 0.061" L x 0.031" W respectively) and maximum seated height of 0.020" (0.50mm). These variations remain within 0603 package tolerance and do not affect PCB layout compatibility.

Q: Do all substitute parts have the same moisture sensitivity level?

A: Yes. All identified substitutes maintain MSL 1 (Unlimited) rating, identical to the RC1608F3573CS. No special moisture control measures are required during storage or handling.

Q: Which substitute offers the best inventory availability?

A: RC0603FR-07357KL (YAGEO) shows the highest inventory level at 130,966 pieces. CRCW0603357KFKEA (Vishay Dale) and RMCF0603FT357K (Stackpole Electronics Inc) provide substantial inventory at 25,638 and 27,461 pieces respectively.

Q: Are all substitutes packaged in Tape & Reel format?

A: Yes. All identified substitute parts are supplied in Tape & Reel (TR) packaging, matching the original RC1608F3573CS packaging format.

Q: Can these parts be used interchangeably on the same PCB assembly?

A: Yes. All substitute parts conform to 0603 (1608 Metric) package specifications with identical termination count (2) and compatible physical dimensions. PCB footprints designed for RC1608F3573CS accommodate all identified substitutes without modification.
