Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RMC1/16K8661FTP is determined by strict equivalence across the following parameters:

Critical Substitution Parameters:

• Resistance value: 8.66 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 ~ 155°C (exact match required)
• Termination count: 2 (exact match required)

All identified substitute parts meet these critical parameters. Substitute parts may differ in packaging format (Tape & Reel versus Cut Tape & Digi-Reel), manufacturer certifications (such as AEC-Q200 automotive qualification), and physical dimensions within tolerance ranges. These differences do not affect functional equivalence in standard applications.

Parameter Comparison

Engineering Selection Recommendations

All four parts are functionally equivalent for applications requiring 8.66 kOhms ±1% 0.1W 0603 thick film resistors within the -55°C to 155°C operating range.

Frequently Asked Questions (FAQ)

Q: Can ERJ-3EKF8661V replace RMC1/16K8661FTP in all applications?

A: ERJ-3EKF8661V meets all critical electrical and mechanical parameters for functional equivalence. The primary difference is packaging format (Cut Tape & Digi-Reel versus Tape & Reel) and automotive AEC-Q200 certification. Compatibility depends on assembly equipment capability to handle the specified packaging format and whether automotive certification is required by the application.

Q: What is the significance of AEC-Q200 certification on RMCF0603FT8K66 and ERJ-3EKF8661V?

A: AEC-Q200 is an automotive industry qualification standard. Parts bearing this certification have undergone testing and qualification for automotive applications. If your application is automotive or requires automotive-grade components, select RMCF0603FT8K66 or ERJ-3EKF8661V. For non-automotive applications, this certification is not a functional requirement.

Q: Does the moisture-resistant feature of RC0603FR-078K66L provide additional benefit?

A: RC0603FR-078K66L includes moisture-resistant construction as a specified feature. All parts listed have MSL 1 (Unlimited) rating, indicating they do not require special moisture control during storage or handling. The moisture-resistant feature of the YAGEO part provides additional protection in high-humidity operating environments but is not required for standard applications.

Q: Are there physical dimension differences between substitute parts?

A: RMC1/16K8661FTP, ERJ-3EKF8661V, and RC0603FR-078K66L have identical dimensions of 0.063" L x 0.031" W (1.60mm x 0.80mm). RMCF0603FT8K66 has a length of 0.061" (1.55mm) with identical width of 0.031" (0.80mm). All parts have identical maximum seated height of 0.022" (0.55mm). These minor dimensional variations are within 0603 package tolerance and do not affect PCB layout or assembly compatibility.

Q: Which substitute part has the highest inventory availability?

A: RC0603FR-078K66L (YAGEO) has 220,251 pieces in stock. RMCF0603FT8K66 (Stackpole) has 221,450 pieces. ERJ-3EKF8661V (Panasonic) has 109,563 pieces. RMC1/16K8661FTP (Kamaya) has 787 pieces. Inventory levels should be verified at time of procurement as availability changes continuously.

Q: Can I mix different manufacturers' parts in the same production batch?

A: All parts are functionally equivalent and meet identical electrical specifications. Mixing manufacturers in the same batch is technically permissible from an electrical standpoint. However, manufacturing and quality control practices may differ between suppliers. Consult your quality assurance procedures regarding multi-source component usage in production.
