Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC1608F6983CS is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 698 kOhms
• Tolerance: ±1%
• Power rating: 0.1W (1/10W)
• Package: 0603 (1608 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C
• Moisture Sensitivity Level: 1 (Unlimited)
• RoHS3 compliance

All identified substitute parts meet these mandatory parameters. Substitute parts are grouped into three categories based on product availability and certification status:

Direct Substitute (Equivalent Availability): RC0603FR-07698KL by YAGEO maintains identical electrical and mechanical specifications with active product status and standard moisture-resistant construction.

Upgrade Substitute (Enhanced Availability, Discontinued Status): MCR03ERTF6983 by Rohm Semiconductor provides electrical equivalence but is discontinued at DiGi Electronics, making it suitable only when existing inventory is accessible.

Similar Substitutes (Enhanced Certifications): CRCW0603698KFKEA (Vishay Dale), ERJ-3EKF6983V (Panasonic), and RMCF0603FT698K (Stackpole Electronics) add automotive AEC-Q200 qualification to the base specification, enabling use in automotive applications where this certification is required.

Parameter Comparison

Engineering Selection Recommendations

For Standard Industrial Applications: RC0603FR-07698KL (YAGEO) is the primary direct substitute. This part maintains full electrical and mechanical equivalence with active product status and standard inventory availability (30,986 pcs in stock), providing the most straightforward replacement path for the RC1608F6983CS.

For Automotive Applications: CRCW0603698KFKEA (Vishay Dale), ERJ-3EKF6983V (Panasonic), or RMCF0603FT698K (Stackpole Electronics) are required when AEC-Q200 automotive qualification is mandated by design specifications. All three parts maintain identical electrical parameters while adding automotive-grade certification. ERJ-3EKF6983V offers the highest inventory availability (55,622 pcs).

For Discontinued Part Replacement: MCR03ERTF6983 (Rohm Semiconductor) is not recommended for new designs due to discontinued status at DiGi Electronics, despite current inventory availability (1,813 pcs). This part is suitable only for legacy system maintenance where existing stock is accessible.

Packaging Consideration: All substitute parts are supplied in Tape & Reel (TR) format except MCR03ERTF6983, which uses Cut Tape (CT) & Digi-Reel® packaging. Verify packaging compatibility with assembly equipment specifications.

Frequently Asked Questions (FAQ)

Q: Can RC0603FR-07698KL replace RC1608F6983CS in any application?

A: Yes. RC0603FR-07698KL meets all mandatory electrical and mechanical parameters: 698 kOhms ±1% resistance, 0.1W power rating, 0603 package, thick film composition, ±100ppm/°C temperature coefficient, -55°C to 155°C operating range, MSL 1 rating, and RoHS3 compliance. No design modifications are required.

Q: What is the difference between the standard parts and AEC-Q200 qualified parts?

A: CRCW0603698KFKEA, ERJ-3EKF6983V, and RMCF0603FT698K include AEC-Q200 automotive qualification certification. This certification is required only for automotive applications. For non-automotive use, standard parts (RC1608F6983CS or RC0603FR-07698KL) are fully adequate.

Q: Are there dimensional differences between substitute parts?

A: Minor dimensional variations exist within tolerance. RC1608F6983CS and ERJ-3EKF6983V measure 0.063" L x 0.031" W (1.60mm x 0.80mm). CRCW0603698KFKEA and RMCF0603FT698K measure 0.061" L x 0.033" W (1.55mm x 0.85mm) and 0.061" L x 0.031" W (1.55mm x 0.80mm) respectively. All fit within 0603 package specifications and are compatible with standard PCB footprints.

Q: Why is MCR03ERTF6983 marked as discontinued?

A: MCR03ERTF6983 is discontinued at DiGi Electronics as a distribution channel, though current inventory (1,813 pcs) remains available. This part should not be selected for new designs. Use active-status alternatives instead.

Q: Which substitute offers the best inventory availability?

A: ERJ-3EKF6983V (Panasonic) provides the highest inventory level at 55,622 pcs in stock, followed by RC0603FR-07698KL (YAGEO) at 30,986 pcs. Both are active products with immediate availability.

Q: Are all substitutes RoHS3 compliant?

A: Yes. All listed substitute parts (RC0603FR-07698KL, MCR03ERTF6983, CRCW0603698KFKEA, ERJ-3EKF6983V, RMCF0603FT698K) are RoHS3 compliant and REACH unaffected, matching the compliance status of RC1608F6983CS.

Q: Can I use these parts interchangeably on the same PCB?

A: Yes, for electrical function. All parts are electrically and mechanically equivalent within the 0603 package specification. However, verify that your assembly process accommodates the packaging format (Tape & Reel vs. Cut Tape) and any minor dimensional variations noted above.
