Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RMC1/16K4643FTP are qualified based on the following criteria:

Electrical Parameters (Critical):

• Resistance value: 464 kOhms
• Tolerance: ±1%
• Power rating: 0.1W (1/10W)
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C

Mechanical Parameters (Critical):

• Package type: 0603 (1608 Metric)
• Number of terminations: 2
• Composition: Thick Film

Environmental & Compliance Parameters:

• Moisture Sensitivity Level: MSL 1 (Unlimited)
• REACH Status: REACH Unaffected
• Packaging: Tape & Reel (TR)

All identified substitute parts match these core parameters. Additional certifications such as AEC-Q200 automotive qualification and RoHS3 compliance are noted where applicable but do not disqualify parts from substitution eligibility.

Parameter Comparison

Engineering Selection Recommendations

All four parts listed—RMC1/16K4643FTP (Kamaya Inc.), ERJ-3EKF4643V (Panasonic Electronic Components), RC0603FR-07464KL (YAGEO), and RMCF0603FT464K (Stackpole Electronics Inc.)—are functionally equivalent for direct substitution based on matching electrical and mechanical specifications.

Compliance Considerations:

ERJ-3EKF4643V and RMCF0603FT464K carry AEC-Q200 automotive qualification ratings, suitable for applications requiring automotive-grade component reliability. RC0603FR-07464KL features moisture-resistant construction. All substitute parts are RoHS3 compliant and REACH unaffected.

Inventory Availability:

RC0603FR-07464KL (YAGEO) maintains the highest inventory level at 147,900 pieces. ERJ-3EKF4643V (Panasonic) provides 89,735 pieces, and RMCF0603FT464K (Stackpole) offers 57,750 pieces. The original RMC1/16K4643FTP (Kamaya) has 824 pieces in stock.

Dimensional Consistency:

RMCF0603FT464K (Stackpole) specifies a length of 0.061" (1.55mm) compared to 0.063" (1.60mm) for the other parts. All other dimensions remain consistent across all four parts.

Frequently Asked Questions (FAQ)

Q: Can ERJ-3EKF4643V replace RMC1/16K4643FTP directly?

A: Yes. Both parts share identical electrical specifications (464 kOhms ±1%, 0.1W, ±100ppm/°C), mechanical package (0603), and environmental ratings (MSL 1). ERJ-3EKF4643V includes AEC-Q200 automotive qualification as an additional feature.

Q: What is the difference between RC0603FR-07464KL and the other substitutes?

A: RC0603FR-07464KL is specified with moisture-resistant construction. All electrical and mechanical parameters remain identical to other substitutes. This part does not carry AEC-Q200 automotive certification.

Q: Are RMCF0603FT464K and RMC1/16K4643FTP mechanically interchangeable?

A: Yes. RMCF0603FT464K has a slightly shorter length (0.061" vs 0.063"), but both conform to the 0603 (1608 Metric) package standard. Height and width dimensions are identical. This minor dimensional variation does not affect PCB assembly or circuit functionality.

Q: Which substitute part has the best availability?

A: RC0603FR-07464KL (YAGEO) has the highest inventory at 147,900 pieces in stock.

Q: Do all substitute parts meet REACH compliance?

A: Yes. All four parts—RMC1/16K4643FTP, ERJ-3EKF4643V, RC0603FR-07464KL, and RMCF0603FT464K—are REACH Unaffected.

Q: Can I use ERJ-3EKF4643V or RMCF0603FT464K in automotive applications?

A: Both ERJ-3EKF4643V and RMCF0603FT464K carry AEC-Q200 automotive qualification ratings. RMC1/16K4643FTP and RC0603FR-07464KL do not specify AEC-Q200 certification.

Q: Are all parts RoHS3 compliant?

A: RC0603FR-07464KL, ERJ-3EKF4643V, and RMCF0603FT464K are explicitly RoHS3 compliant. RMC1/16K4643FTP does not specify RoHS status in the provided data.
