RC3216F54R9CS Equivalent & Substitute Parts Reference

Part Overview

The RC3216F54R9CS is a 54.9 Ohm ±1% thick film chip resistor manufactured by Samsung Electro-Mechanics, rated for 0.25W (1/4W) power dissipation in a 1206 (3216 Metric) surface mount package. This component is classified as Active product status with moisture resistant characteristics and operates across the temperature range of -55°C to 155°C. The part is ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating.

Equivalent and substitute parts are identified based on matching electrical specifications (resistance value, tolerance, power rating, temperature coefficient) and mechanical compatibility (package type, dimensions, termination count). Alternative sources become necessary for supply chain continuity, lead time optimization, or design flexibility across manufacturing partners.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Requirements:

• Resistance value: 54.9 Ohms (exact match)
• Tolerance: ±1% (exact match)
• Power rating: 0.25W / 1/4W (exact match)
• Temperature coefficient: ±100ppm/°C (exact match)
• Operating temperature range: -55°C to 155°C (exact match or wider)
• Composition: Thick Film (exact match)

Mechanical Equivalence Requirements:

• Package type: 1206 (3216 Metric) (exact match)
• Number of terminations: 2 (exact match)
• RoHS compliance: ROHS3 Compliant (exact match)
• Moisture sensitivity: MSL 1 (Unlimited) (exact match or better)

All identified substitute parts meet these criteria. Variations in physical dimensions (length, width, height) within the 1206 package specification, packaging format (Tape & Reel vs. Cut Tape), and optional automotive certifications (AEC-Q200) do not affect functional substitutability for standard applications.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection (Active Status):

RC1206FR-0754R9L (YAGEO) and RMCF1206FT54R9 (Stackpole) are recommended as primary substitutes. Both maintain Active product status, ensuring long-term availability and continued manufacturer support. YAGEO RC1206FR-0754R9L offers the largest inventory position (10,276 pcs) with moisture resistant characteristics matching the original specification. RMCF1206FT54R9 provides automotive AEC-Q200 qualification for applications requiring automotive-grade reliability.

Secondary Selection (Automotive Applications):

CRCW120654R9FKEA (Vishay Dale) is suitable for automotive and industrial applications requiring AEC-Q200 certification. This part maintains Active status with 15,254 pcs inventory availability and the lowest seated height (0.024") among substitute options.

Conditional Selection (Supply Chain Alternatives):

ERJ-8ENF54R9V (Panasonic) carries the highest inventory (43,732 pcs) but is classified as Not For New Designs. This part is suitable only for sustaining production of existing designs or temporary supply chain solutions. MCR18ERTF54R9 (Rohm) is discontinued at DiGi Electronics and should not be selected for new applications.

Compliance Verification:

All substitute parts maintain ROHS3 compliance, MSL 1 (Unlimited) rating, and REACH Unaffected status, matching the original RC3216F54R9CS specification. No additional compliance verification is required for direct substitution.

Frequently Asked Questions (FAQ)

Q: Can ERJ-8ENF54R9V be used as a direct replacement for RC3216F54R9CS?

A: ERJ-8ENF54R9V meets all electrical and mechanical specifications for direct substitution. However, it is classified as Not For New Designs. Use this part only for sustaining production of existing designs where the original part number is already established in manufacturing documentation.

Q: What is the difference between automotive-rated and standard versions?

A: RMCF1206FT54R9 and CRCW120654R9FKEA include AEC-Q200 automotive qualification, indicating compliance with automotive reliability and quality standards. Standard versions (RC3216F54R9CS, RC1206FR-0754R9L) do not carry this certification. For non-automotive applications, both types are electrically and mechanically equivalent.

Q: Are there dimensional differences between substitute parts?

A: All parts conform to the 1206 (3216 Metric) package specification. Minor variations exist within tolerance: length ranges from 0.120" to 0.126" (3.05mm to 3.20mm), width is 0.061" to 0.063" (1.55mm to 1.60mm), and seated height ranges from 0.024" to 0.028" (0.60mm to 0.70mm). These variations do not affect PCB layout or assembly compatibility.

Q: What packaging formats are available?

A: RC3216F54R9CS is supplied in standard packaging format. Substitute parts are available in Tape & Reel (TR) format (ERJ-8ENF54R9V, RC1206FR-0754R9L, RMCF1206FT54R9, CRCW120654R9FKEA) or Cut Tape (CT) & Digi-Reel® format (MCR18ERTF54R9). Packaging format does not affect component performance or substitutability.

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

A: RC1206FR-0754R9L (YAGEO) and CRCW120654R9FKEA (Vishay Dale) both maintain Active product status with substantial inventory levels (10,276 pcs and 15,254 pcs respectively), indicating strong long-term availability commitment from manufacturers.

Q: Can MCR18ERTF54R9 be used in new designs?

A: MCR18ERTF54R9 is discontinued at DiGi Electronics and should not be selected for new designs. Use only for sustaining production of existing designs where this part number is already qualified and documented.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All identified substitute parts (ERJ-8ENF54R9V, RC1206FR-0754R9L, RMCF1206FT54R9, CRCW120654R9FKEA, MCR18ERTF54R9) are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating, matching the original RC3216F54R9CS specification.
