RCS3216F44R2CS Equivalent & Substitute Parts

Part Overview

The RCS3216F44R2CS 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 resistor features anti-sulfur and moisture-resistant properties with a temperature coefficient of ±100ppm/°C and operating range of -55°C to 155°C. The part is currently in active production status with ROHS3 compliance and unlimited moisture sensitivity level (MSL 1).

Equivalent and substitute parts are identified based on matching electrical specifications (resistance value, tolerance, power rating) and mechanical compatibility (package size, termination count, physical dimensions). Substitute parts may vary in specific features such as automotive qualification or pulse withstanding capability while maintaining core functional equivalence.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict equivalence in the following core parameters:

Mandatory Matching Parameters:

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

Variable Parameters (Allowable Differences):

• Power Rating: 0.25W or higher (0.75W acceptable for higher power applications)
• Manufacturer: Different manufacturers permitted
• Packaging format: Tape & Reel acceptable
• Features: Additional features (automotive AEC-Q200, pulse withstanding, anti-sulfur) do not disqualify substitution
• Physical height variation: Within 1206 package specification tolerance

All identified substitute parts meet the mandatory matching parameters and are therefore electrically and mechanically compatible with the RCS3216F44R2CS.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Active Status, Recommended for New Designs):

CR1206-FX-44R2ELF (Bourns Inc.), CRCW120644R2FKEA (Vishay Dale), and RC1206FR-0744R2L (YAGEO) are direct functional equivalents with active product status. These parts are suitable for new design implementations and provide full compatibility with the RCS3216F44R2CS in terms of electrical performance and mechanical fit.

Enhanced Capability Substitute:

CRCW120644R2FKEAHP (Vishay Dale) provides increased power rating (0.75W versus 0.25W) while maintaining all other electrical and mechanical specifications. This part is appropriate for applications requiring higher power dissipation capability within the same package footprint.

Legacy Status Substitute:

ERJ-8ENF44R2V (Panasonic Electronic Components) meets all electrical and mechanical equivalence criteria but carries "Not For New Designs" product status. This part is suitable only for replacement or repair of existing assemblies and should not be selected for new product development.

Compliance Considerations:

All substitute parts maintain ROHS3 compliance, unlimited moisture sensitivity level (MSL 1), and identical operating temperature range (-55°C to 155°C). Automotive-qualified variants (CRCW120644R2FKEA, CRCW120644R2FKEAHP, ERJ-8ENF44R2V) carry AEC-Q200 certification, which does not affect substitution eligibility but may be relevant for automotive applications.

Frequently Asked Questions (FAQ)

Q: Can CRCW120644R2FKEAHP (0.75W) be used as a direct replacement for RCS3216F44R2CS (0.25W)?

A: Yes. The CRCW120644R2FKEAHP is electrically and mechanically compatible. The higher power rating (0.75W) does not prevent substitution; it indicates the part can safely dissipate more power. In applications where the original 0.25W rating is sufficient, the 0.75W part will operate within its design envelope.

Q: What is the difference between CR1206-FX-44R2ELF and RC1206FR-0744R2L?

A: Both parts are functionally equivalent with identical electrical specifications (44.2 Ω, ±1%, 0.25W, 1206 package). The primary differences are manufacturer (Bourns versus YAGEO) and minor physical height variation (0.75mm versus 0.65mm). Both are suitable for direct substitution.

Q: Why is ERJ-8ENF44R2V marked "Not For New Designs"?

A: This designation indicates the manufacturer (Panasonic) has discontinued active development of this product line. While the part remains functionally equivalent and available in inventory, it should not be selected for new product designs. Use active-status alternatives for new implementations.

Q: Are the automotive-qualified parts (AEC-Q200) necessary for non-automotive applications?

A: No. AEC-Q200 certification is an additional qualification that does not affect core electrical or mechanical performance. Non-automotive applications can use either qualified or non-qualified variants. Selection should be based on application requirements, not certification status alone.

Q: Can these parts be used interchangeably in existing PCB designs?

A: Yes. All substitute parts share identical 1206 (3216 Metric) package dimensions and two-terminal configuration. PCB footprints designed for RCS3216F44R2CS will accommodate all listed substitutes without modification.

Q: What is the significance of the ±100ppm/°C temperature coefficient?

A: This specification indicates the resistor's resistance value will change by approximately 100 parts per million for each degree Celsius change in operating temperature. All listed parts share this specification, ensuring equivalent temperature stability across the -55°C to 155°C operating range.

Q: Is moisture sensitivity level (MSL 1) the same across all parts?

A: Yes. All parts, including the main part and all substitutes, carry MSL 1 (Unlimited) rating. This means no moisture sensitivity precautions are required during storage, handling, or assembly.
