RMC1/16-4704FTP Equivalent & Substitute Parts

Part Overview

The RMC1/16-4704FTP is a 4.7 MOhms ±1% thick film chip resistor manufactured by Kamaya Inc. in 0603 (1608 Metric) package format with 0.1W power rating. This component is classified as Active product status with 658 pieces currently in stock. Substitute parts are identified when equivalent electrical specifications, mechanical dimensions, and packaging requirements are met across alternative manufacturers. Selection of substitute components becomes necessary when primary inventory is unavailable, when supply chain optimization is required, or when specific certifications or features are mandated by application requirements.

Substitute Part Grouping Explanation

Substitution eligibility for the RMC1/16-4704FTP is determined by strict equivalence across the following parameters: resistance value (4.7 MOhms), tolerance (±1%), power rating (0.1W), package format (0603 / 1608 Metric), composition (thick film), operating temperature range (-55°C ~ 155°C), and termination count (2). All identified substitute parts meet these core electrical and mechanical criteria. Temperature coefficient values may vary within acceptable engineering margins (±100ppm/°C to ±200ppm/°C). Packaging format (Tape & Reel versus Cut Tape) represents a logistical distinction without impact on component functionality. Certifications such as AEC-Q200 and RoHS3 compliance are additional qualifications that do not disqualify parts from substitution but indicate enhanced qualification levels for specific applications.

Engineering Selection Recommendations

All five components listed meet the core electrical and mechanical substitution criteria for the RMC1/16-4704FTP. Selection among these alternatives is based on application-specific requirements and regulatory compliance mandates.

RMCF0603FT4M70 (Stackpole Electronics Inc) carries AEC-Q200 automotive qualification and is suitable for automotive applications requiring enhanced reliability standards. Temperature coefficient specification of ±200ppm/°C represents a wider tolerance margin compared to the primary part. This component is available in high inventory volume (47,904 pieces).

CRG0603F4M7 (TE Connectivity Passive Product) maintains identical temperature coefficient (±100ppm/°C) and dimensional specifications to the primary part. RoHS3 compliance is confirmed. REACH status is listed as Vendor Undefined. Inventory availability is 929 pieces.

KTR03EZPF4704 (Rohm Semiconductor) combines AEC-Q200 automotive qualification with high voltage capability designation. Temperature coefficient matches the primary specification (±100ppm/°C). RoHS3 and REACH compliance are confirmed. Inventory level is 5,950 pieces.

RC0603FR-074M7L (YAGEO) features moisture-resistant thick film composition and maintains ±100ppm/°C temperature coefficient. RoHS3 and REACH compliance are confirmed. This component offers the highest inventory availability at 317,952 pieces, supporting supply chain continuity and cost optimization.

Frequently Asked Questions (FAQ)

Q: Can RMCF0603FT4M70 be used as a direct replacement for RMC1/16-4704FTP?

A: Yes. Both components share identical resistance (4.7 MOhms), tolerance (±1%), power rating (0.1W), package format (0603), and operating temperature range (-55°C ~ 155°C). The temperature coefficient of RMCF0603FT4M70 is ±200ppm/°C compared to ±100ppm/°C for the primary part, which represents acceptable variance for thick film resistor applications. AEC-Q200 qualification of the Stackpole component provides additional automotive-grade reliability assurance.

Q: What is the significance of the temperature coefficient difference between RMC1/16-4704FTP (±100ppm/°C) and RMCF0603FT4M70 (±200ppm/°C)?

A: Temperature coefficient defines the fractional change in resistance per degree Celsius. A ±200ppm/°C specification indicates twice the potential resistance drift over temperature compared to ±100ppm/°C. For high-precision analog circuits or applications with strict tolerance requirements across wide temperature ranges, the ±100ppm/°C specification is preferred. For general-purpose applications, ±200ppm/°C remains within acceptable engineering margins.

Q: Are there packaging format differences among the substitute parts?

A: Yes. RMC1/16-4704FTP and most substitutes are supplied in Tape & Reel (TR) format. RC0603FR-074M7L from YAGEO is supplied in Cut Tape (CT) & Digi-Reel® format. Both packaging formats contain identical components; the difference is logistical. Tape & Reel format is optimized for automated assembly processes, while Cut Tape format supports manual or lower-volume assembly operations.

Q: Which substitute part offers the best supply chain availability?

A: RC0603FR-074M7L (YAGEO) provides the highest inventory level at 317,952 pieces in stock. This component is suitable for applications requiring immediate availability and supply chain risk mitigation. All substitute parts maintain Active product status, confirming ongoing manufacturer support.

Q: Do all substitute parts meet RoHS3 compliance?

A: Four of the five substitute parts (RMCF0603FT4M70, CRG0603F4M7, KTR03EZPF4704, and RC0603FR-074M7L) are confirmed RoHS3 compliant. The primary part RMC1/16-4704FTP does not specify RoHS status in the provided data. For applications requiring RoHS3 certification, any of the four compliant substitutes are appropriate selections.

Q: What is the difference between AEC-Q200 qualified parts and standard parts?

A: AEC-Q200 is an automotive industry qualification standard requiring enhanced reliability testing, including thermal cycling, humidity resistance, and failure rate validation. RMCF0603FT4M70 and KTR03EZPF4704 carry AEC-Q200 ratings, making them suitable for automotive and mission-critical applications. Standard parts without AEC-Q200 qualification are appropriate for general industrial and consumer applications.

Q: Are dimensional variations between substitute parts significant?

A: RMCF0603FT4M70 has a length of 0.061" (1.55mm) compared to 0.063" (1.60mm) for other parts. This 0.05mm difference is within standard 0603 package tolerance and does not affect PCB layout or assembly compatibility. All parts maintain identical height (0.022" / 0.55mm) and width (0.031" / 0.80mm) specifications.
