RC3216F44R2CS Equivalent & Substitute Parts

Part Overview

The RC3216F44R2CS is a 44.2 Ohm ±1% 0.25W (1/4W) chip resistor manufactured by Samsung Electro-Mechanics in the 1206 (3216 Metric) package. This thick film, moisture-resistant resistor operates across a temperature range of -55°C to 155°C with a temperature coefficient of ±100ppm/°C. The part is currently in active production status and carries ROHS3 compliance with MSL 1 (Unlimited) moisture sensitivity rating.

Equivalent and substitute parts are identified to support procurement flexibility, inventory management, and design continuity when the primary part becomes unavailable or when alternative sourcing is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC3216F44R2CS is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 44.2 Ohms
• Tolerance: ±1%
• Package / Case: 1206 (3216 Metric)
• Composition: Thick Film
• Temperature Coefficient: ±100ppm/°C
• Operating Temperature Range: -55°C ~ 155°C
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)
• Number of Terminations: 2

Allowable Variation Parameters:

• Power Rating: Substitutes with equal or higher power rating are acceptable
• Physical dimensions: Minor variations within supplier specifications are acceptable
• Packaging format: Tape & Reel (TR) is compatible with the original packaging
• Manufacturer: Different manufacturers are acceptable provided all electrical and mechanical parameters match

Substitutes are classified as Direct when all parameters match exactly, or Similar when power rating or specific features (such as automotive qualification) differ while maintaining core electrical compatibility.

Parameter Comparison

Engineering Selection Recommendations

Direct Substitutes (Fully Compatible):

The CR1206-FX-44R2ELF (Bourns Inc.) and RC1206FR-0744R2L (YAGEO) are direct substitutes for the RC3216F44R2CS. Both parts match all critical electrical and mechanical parameters, maintain identical power ratings, and carry active product status with ROHS3 compliance. These parts are suitable for direct replacement in existing designs without circuit modification.

Similar Substitutes (Compatible with Considerations):

The CRCW120644R2FKEA (Vishay Dale) is a similar substitute that matches all core parameters but includes automotive AEC-Q200 qualification. This additional qualification does not preclude its use in non-automotive applications and provides enhanced reliability documentation.

The CRCW120644R2FKEAHP (Vishay Dale) is a similar substitute with a higher power rating of 0.75W (3/4W) and pulse withstanding capability. The increased power rating provides additional thermal margin and is electrically compatible. This part is suitable for applications requiring enhanced power dissipation capability.

The ERJ-8ENF44R2V (Panasonic Electronic Components) is a similar substitute with automotive AEC-Q200 qualification. However, this part carries a "Not For New Designs" product status. Use of this part is restricted to legacy design support and existing production continuity only.

Selection Criteria:

For new designs, select from parts with Active product status: CR1206-FX-44R2ELF, RC1206FR-0744R2L, CRCW120644R2FKEA, or CRCW120644R2FKEAHP.

For applications requiring automotive qualification, select CRCW120644R2FKEA or CRCW120644R2FKEAHP.

For applications with elevated power dissipation requirements, select CRCW120644R2FKEAHP.

For legacy design continuity, ERJ-8ENF44R2V remains available but is not recommended for new designs.

Frequently Asked Questions (FAQ)

Q: Can I use a substitute part with a higher power rating than the original RC3216F44R2CS?

A: Yes. The CRCW120644R2FKEAHP with 0.75W (3/4W) rating is electrically compatible and can be used as a direct replacement. The higher power rating provides additional thermal capability and does not negatively impact circuit performance. Physical dimensions remain within the 1206 package specification.

Q: Are all substitute parts available in Tape & Reel (TR) packaging?

A: Yes. All listed substitute parts are available in Tape & Reel (TR) packaging, which is compatible with standard surface mount assembly processes.

Q: What is the difference between Direct and Similar substitutes?

A: Direct substitutes match all electrical and mechanical parameters exactly, including power rating and features. Similar substitutes match core electrical parameters but may include additional features (such as automotive qualification) or different power ratings. All listed substitutes are electrically compatible with the original part.

Q: Can I use ERJ-8ENF44R2V in a new design?

A: No. The ERJ-8ENF44R2V carries a "Not For New Designs" product status and is restricted to legacy design support and existing production continuity. For new designs, select from parts with Active status: CR1206-FX-44R2ELF, RC1206FR-0744R2L, CRCW120644R2FKEA, or CRCW120644R2FKEAHP.

Q: Do all substitute parts meet RoHS3 compliance?

A: Yes. All listed substitute parts are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating, matching the original RC3216F44R2CS specification.

Q: What is the significance of AEC-Q200 qualification on some substitute parts?

A: AEC-Q200 is an automotive industry qualification standard. Parts with this qualification have undergone additional reliability testing and documentation. This qualification does not restrict use in non-automotive applications and provides enhanced reliability assurance for demanding environments.

Q: Are there physical dimension differences between substitute parts?

A: Minor variations exist within the 1206 package specification. The RC1206FR-0744R2L measures 0.122" L x 0.063" W (3.10mm x 1.60mm), while CR1206-FX-44R2ELF and CRCW120644R2FKEA measure 0.126" L x 0.063" W (3.20mm x 1.60mm). All dimensions fall within standard 1206 package tolerances and are compatible with standard PCB footprints.

Q: Can I mix different substitute parts in the same production run?

A: Yes. All substitute parts are electrically and mechanically equivalent and can be used interchangeably. However, design documentation should specify the approved part list to maintain traceability and consistency.
