RCS3216F4642CS Equivalent & Substitute Parts

Part Overview

The RCS3216F4642CS is a 46.4 kOhms ±1% 0.25W chip resistor in 1206 (3216 Metric) package manufactured by Samsung Electro-Mechanics. This thick film resistor features anti-sulfur and moisture-resistant properties, operating across -55°C to 155°C with a temperature coefficient of ±100ppm/°C. The component is RoHS3 compliant and carries MSL Level 1 (Unlimited) moisture sensitivity rating.

Substitute components become necessary when the primary part experiences supply constraints, extended lead times, or inventory limitations. The RCS3216F4642CS maintains 829 pieces in current stock; however, alternative sources provide significantly higher inventory availability while maintaining identical electrical specifications and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution validity for the RCS3216F4642CS is determined by strict equivalence across the following parameters:

Critical Electrical Parameters:

• Resistance value: 46.4 kOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Power rating: 0.25W / 1/4W (exact match required)
• Temperature coefficient: ±100ppm/°C (exact match required)
• Operating temperature range: -55°C ~ 155°C (exact match required)

Critical Mechanical Parameters:

• Package / Case: 1206 (3216 Metric) (exact match required)
• Number of terminations: 2 (exact match required)

Compliance Parameters:

• RoHS3 compliance (required)
• Moisture Sensitivity Level 1 (required)

All four substitute parts listed below meet these criteria without exception. Substitution is valid for direct component replacement in circuit designs where the RCS3216F4642CS was originally specified.

Engineering Selection Recommendations

Primary Substitutes (Active Product Status):

CR1206-FX-4642ELF (Bourns Inc.) and CRCW120646K4FKEA (Vishay Dale) are recommended as primary substitutes. Both components carry Active product status, ensuring long-term availability and continued manufacturer support. CRCW120646K4FKEA includes AEC-Q200 automotive qualification, providing additional reliability assurance for applications requiring automotive-grade components.

RC1206FR-0746K4L (YAGEO) is an Active product with the lowest dimensional height (0.026" seated), suitable for space-constrained applications where board clearance is critical.

Secondary Substitute (Legacy Status):

ERJ-8ENF4642V (Panasonic Electronic Components) carries "Not For New Designs" product status. This component is electrically and mechanically equivalent but should be selected only when existing inventory must be consumed or when legacy system maintenance requires exact historical component matching. The part maintains the highest current inventory (58,753 pieces), making it suitable for high-volume legacy production runs.

Compliance Considerations:

All substitute parts maintain ROHS3 compliance and MSL Level 1 rating, ensuring compatibility with modern manufacturing processes and storage requirements. No additional handling or environmental controls are required beyond standard component storage practices.

Frequently Asked Questions (FAQ)

Q: Can CR1206-FX-4642ELF replace RCS3216F4642CS in existing circuit designs?

A: Yes. CR1206-FX-4642ELF is electrically and mechanically equivalent. Both components share identical resistance (46.4 kOhms), tolerance (±1%), power rating (0.25W), package (1206), temperature coefficient (±100ppm/°C), and operating range (-55°C ~ 155°C). Direct substitution is valid without circuit modification.

Q: What is the difference between CRCW120646K4FKEA and other substitutes?

A: CRCW120646K4FKEA includes AEC-Q200 automotive qualification, indicating compliance with automotive reliability standards. This qualification is not present in CR1206-FX-4642ELF or RC1206FR-0746K4L. Select CRCW120646K4FKEA when automotive-grade reliability documentation is required.

Q: Why is ERJ-8ENF4642V marked "Not For New Designs"?

A: "Not For New Designs" indicates the manufacturer (Panasonic) has discontinued active development and marketing of this product line. While the component remains electrically and mechanically equivalent, it should not be selected for new circuit designs. Use ERJ-8ENF4642V only for legacy system maintenance or when consuming existing inventory.

Q: Are there physical dimension differences between substitutes?

A: Yes. Height-seated measurements vary slightly: RCS3216F4642CS (0.026"), CR1206-FX-4642ELF (0.030"), CRCW120646K4FKEA (0.024"), ERJ-8ENF4642V (0.028"), and RC1206FR-0746K4L (0.026"). Length and width remain constant at 0.126" × 0.063" (3.20mm × 1.60mm). These variations are within standard 1206 package tolerances and do not affect PCB layout compatibility.

Q: Do all substitutes require identical packaging specifications?

A: No. RCS3216F4642CS uses standard packaging (not specified), while substitutes are available in Tape & Reel (TR) or Cut Tape (CT) & Digi-Reel® formats. Packaging format does not affect component electrical or mechanical performance. Select packaging based on assembly process requirements (automated pick-and-place systems typically require Tape & Reel format).

Q: Are moisture sensitivity handling procedures identical for all parts?

A: Yes. All parts carry MSL Level 1 (Unlimited) rating, indicating no moisture sensitivity restrictions. Standard component storage at room temperature and normal humidity is acceptable. No special desiccant storage, baking procedures, or moisture barrier packaging is required.
