Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RMC1/10K4640FTP is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Resistance value: 464 Ohms (exact match required)
• Tolerance: ±1% (exact match required)
• Power rating: 0.125W / 1/8W (exact match required)
• Temperature coefficient: ±100ppm/°C (exact match required)
• Operating temperature range: -55°C ~ 155°C (exact match required)

Mechanical Parameters:

• Package / Case: 0805 (2012 Metric) (exact match required)
• Composition: Thick Film (exact match required)
• Number of terminations: 2 (exact match required)

Environmental & Compliance Parameters:

• Moisture Sensitivity Level: 1 (Unlimited) (exact match required)
• REACH Status: REACH Unaffected (exact match required)

All substitute parts listed below meet these criteria. Additional features such as Automotive AEC-Q200 certification or moisture resistance represent enhancements that do not prevent substitution but may provide additional qualification for specific applications.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Active Status, Highest Availability):

ERJ-6ENF4640V (Panasonic Electronic Components) and RMCF0805FT464R (Stackpole Electronics Inc) are recommended as primary substitutes. Both parts maintain Active product status with substantial inventory availability (117,693 and 3,989 pieces respectively). Both carry Automotive AEC-Q200 certification, indicating qualification for automotive-grade applications. ERJ-6ENF4640V offers the highest inventory level for long-term supply security.

Secondary Substitutes (Active Status, Specialized Features):

RC0805FR-07464RL (YAGEO) is suitable for applications requiring moisture-resistant thick film construction. This part maintains Active status with 44,580 pieces in inventory and ROHS3 compliance.

KTR10EZPF4640 (Rohm Semiconductor) is appropriate for high-voltage applications requiring Automotive AEC-Q200 qualification. This part maintains Active status with 8,402 pieces in inventory.

Avoid:

MCR10ERTF4640 (Rohm Semiconductor) is marked as Discontinued at DiGi Electronics and should not be selected for new designs or long-term supply planning, despite current inventory availability of 2,923 pieces.

All recommended substitutes are ROHS3 compliant, REACH unaffected, and carry MSL 1 (Unlimited) moisture sensitivity ratings, ensuring compatibility with standard manufacturing and storage conditions.

Frequently Asked Questions (FAQ)

Q: Can ERJ-6ENF4640V replace RMC1/10K4640FTP directly?

A: Yes. ERJ-6ENF4640V meets all electrical and mechanical specifications: 464 Ohms ±1%, 0.125W power rating, 0805 package, thick film composition, ±100ppm/°C temperature coefficient, and -55°C to 155°C operating range. The Automotive AEC-Q200 feature is an enhancement that does not prevent substitution.

Q: What is the difference between the substitute parts?

A: All substitute parts share identical electrical specifications and package dimensions. Differences exist only in manufacturer, product status, and optional features. ERJ-6ENF4640V and RMCF0805FT464R include Automotive AEC-Q200 certification. KTR10EZPF4640 adds high-voltage capability. RC0805FR-07464RL emphasizes moisture resistance. MCR10ERTF4640 is discontinued and should not be used for new designs.

Q: Are there packaging differences between these parts?

A: RMC1/10K4640FTP is supplied in Tape & Reel (TR) packaging. MCR10ERTF4640 is supplied in Cut Tape (CT) & Digi-Reel® packaging. All other substitutes use Tape & Reel (TR) packaging. The 0805 (2012 Metric) package dimensions are identical across all parts: 0.079" L × 0.049" W (2.00mm × 1.25mm). Height variations are minimal (0.024" to 0.028" seated maximum) and do not affect PCB assembly compatibility.

Q: Which substitute offers the best long-term supply availability?

A: ERJ-6ENF4640V (Panasonic Electronic Components) offers the highest inventory level at 117,693 pieces, providing superior supply security for high-volume or long-term production requirements.

Q: Can I use KTR10EZPF4640 in a standard application?

A: Yes. KTR10EZPF4640 is fully compatible with standard applications. The high-voltage feature is an additional capability that does not restrict use in standard circuits. This part is suitable for both standard and high-voltage applications.

Q: What does MSL 1 (Unlimited) mean for these parts?

A: MSL 1 (Unlimited) indicates that these resistors have unlimited shelf life and do not require special moisture-controlled storage or handling. They can be stored and handled under standard industrial conditions without moisture sensitivity concerns.

Q: Are all these parts RoHS compliant?

A: Yes. All substitute parts listed carry ROHS3 compliance certification. The original RMC1/10K4640FTP does not specify RoHS status in the provided data, but all substitutes meet modern RoHS3 requirements.
