Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RMC1/10K4643FTP is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 464 kOhms
• Tolerance: ±1%
• Power rating: 0.125W (1/8W)
• Package: 0805 (2012 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C to 155°C
• Moisture sensitivity level: 1 (Unlimited)

All identified substitute parts meet these electrical and mechanical specifications. Substitute parts may include additional features such as automotive AEC-Q200 qualification or moisture-resistant construction, which do not prevent substitution but represent enhanced capability levels. Physical dimensions remain within acceptable tolerances for 0805 package format.

Parameter Comparison

Engineering Selection Recommendations

All identified substitute parts satisfy the core electrical and mechanical requirements for direct replacement of the RMC1/10K4643FTP. Selection among available substitutes should be based on the following criteria:

General-Purpose Applications: The RC0805FR-07464KL (YAGEO) offers moisture-resistant construction and is suitable for applications where environmental protection is beneficial. The RMCF0805FT464K (Stackpole Electronics Inc) provides automotive AEC-Q200 qualification for applications requiring automotive-grade reliability.

Automotive Applications: Both ERJ-6ENF4643V (Panasonic Electronic Components) and RMCF0805FT464K (Stackpole Electronics Inc) carry AEC-Q200 ratings. The KTR10EZPF4643 (Rohm Semiconductor) additionally features high-voltage capability, suitable for circuits operating at elevated voltage levels while maintaining the same resistance and tolerance specifications.

Compliance Considerations: All substitute parts are ROHS3 compliant and REACH unaffected. All parts maintain MSL 1 (Unlimited) moisture sensitivity rating, indicating no special storage or handling requirements.

Inventory Availability: Substitute selection may be influenced by current stock levels. YAGEO RC0805FR-07464KL maintains the highest inventory (43,413 pcs), followed by Panasonic ERJ-6ENF4643V (1,572,228 pcs). Kamaya RMC1/10K4643FTP and Stackpole RMCF0805FT464K maintain comparable inventory levels (837-838 pcs).

Frequently Asked Questions (FAQ)

Q: Can ERJ-6ENF4643V replace RMC1/10K4643FTP in non-automotive applications?

A: Yes. The ERJ-6ENF4643V meets all electrical and mechanical specifications required for the RMC1/10K4643FTP. The automotive AEC-Q200 qualification represents enhanced capability and does not restrict use in general-purpose applications.

Q: What is the difference between KTR10EZPF4643 and other substitutes?

A: The KTR10EZPF4643 includes high-voltage capability in addition to automotive AEC-Q200 qualification. All other electrical parameters (resistance, tolerance, power rating, temperature coefficient, operating range) remain identical to the main part and other substitutes.

Q: Are there physical dimension differences between substitute parts?

A: All parts use 0805 (2012 Metric) package format. Height-seated maximum values vary slightly: RMC1/10K4643FTP and KTR10EZPF4643 measure 0.026" (0.65mm), ERJ-6ENF4643V measures 0.028" (0.70mm), and RC0805FR-07464KL measures 0.024" (0.60mm). These variations remain within standard 0805 package tolerances and do not affect PCB layout or assembly compatibility.

Q: Is moisture-resistant construction necessary for the RC0805FR-07464KL?

A: All parts, including the main part RMC1/10K4643FTP, carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity concerns. The moisture-resistant feature of RC0805FR-07464KL provides additional environmental protection but is not required for standard applications.

Q: Can KTR10EZPF4643 be used in high-voltage circuits?

A: The KTR10EZPF4643 is specified with high-voltage capability. However, the specific voltage rating is not provided in the available parameters. Circuit design requirements should be verified against the component datasheet for the intended application voltage.

Q: Are all substitutes available in Tape & Reel packaging?

A: Yes. All identified substitute parts are supplied in Tape & Reel (TR) packaging, matching the packaging format of the main part RMC1/10K4643FTP.

Q: What is the basis for substitution compatibility?

A: Substitution is based on identical electrical specifications (464 kOhms ±1%, 0.125W), identical package format (0805 2012 Metric), identical composition (thick film), identical temperature characteristics (±100ppm/°C, -55°C to 155°C operating range), and identical moisture sensitivity level (MSL 1). All substitute parts meet these criteria.
