Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RMC1/16K4641FTP is determined by strict equivalence across the following parameters:

Critical Matching Parameters:

• Resistance value: 4.64 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: MSL 1 (Unlimited)

All identified substitute parts meet these core electrical and mechanical specifications. Variations in physical dimensions (length 0.061" to 0.063") remain within standard 0603 package tolerances and do not affect circuit board layout compatibility. Additional certifications such as AEC-Q200 automotive qualification or moisture-resistant construction represent enhanced features that do not compromise substitution eligibility for non-automotive or standard applications.

Parameter Comparison

Engineering Selection Recommendations

All four parts are Active product status and meet the core electrical and mechanical specifications for direct substitution. Selection among these alternatives is based on application-specific requirements and supply chain considerations:

For Automotive Applications: ERJ-3EKF4641V (Panasonic) and RMCF0603FT4K64 (Stackpole) both carry AEC-Q200 automotive qualification and ROHS3 compliance, meeting automotive industry standards. RMCF0603FT4K64 provides higher inventory (218,536 pcs) compared to ERJ-3EKF4641V (1,036 pcs).

For Supply Chain Continuity: All substitute parts maintain Active product status and unlimited MSL rating, ensuring long-term availability and consistent performance across thermal cycling and storage conditions.

Frequently Asked Questions (FAQ)

Q: Can ERJ-3EKF4641V replace RMC1/16K4641FTP in non-automotive circuits?

A: Yes. The AEC-Q200 automotive qualification of ERJ-3EKF4641V does not restrict its use in standard applications. All electrical and mechanical parameters remain equivalent.

Q: What is the significance of the moisture-resistant feature in RC0603FR-074K64L?

A: Moisture-resistant construction enhances reliability in high-humidity environments but does not alter electrical performance. Both the main part and all substitutes carry MSL 1 (Unlimited) rating, indicating equivalent moisture sensitivity handling.

Q: Are there physical dimension differences between substitute parts?

A: RMCF0603FT4K64 has a length of 0.061" (1.55mm) compared to 0.063" (1.60mm) for other parts. Both dimensions fall within standard 0603 package tolerances and do not affect PCB layout compatibility.

Q: Which substitute part should be selected for maximum inventory availability?

A: RC0603FR-074K64L (YAGEO) provides the highest inventory level at 352,945 pcs, followed by RMCF0603FT4K64 (Stackpole) at 218,536 pcs.

Q: Do all substitute parts comply with ROHS3 requirements?

A: ERJ-3EKF4641V, RC0603FR-074K64L, and RMCF0603FT4K64 are all ROHS3 compliant. RMC1/16K4641FTP ROHS status is not specified in the provided data.

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

A: Yes. All parts share identical electrical specifications, package designation (0603), and operating parameters. Physical dimension variations (0.061" to 0.063" length) remain within standard tolerances and do not require PCB redesign.
