RC2012F1782CS Equivalent & Substitute Parts Reference

Part Overview

The RC2012F1782CS is a 17.8 kOhms ±1% thick film chip resistor manufactured by Samsung Electro-Mechanics in 0805 (2012 Metric) package format. This surface mount device is rated for 0.125W (1/8W) power dissipation and operates across the temperature range of -55°C to 155°C. The component features moisture-resistant construction with ±100ppm/°C temperature coefficient and is ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating.

Equivalent and substitute parts are identified when design requirements necessitate alternative sourcing due to inventory constraints, supply chain disruptions, or specific application certifications such as automotive AEC-Q200 qualification.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC2012F1782CS is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 17.8 kOhms
• Tolerance: ±1%
• Power rating: 0.125W (1/8W)
• Package: 0805 (2012 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C
• Moisture sensitivity level: 1 (Unlimited)
• Number of terminations: 2

Compliance Considerations: Substitute parts maintain ROHS3 compliance and REACH status alignment. Parts designated as "Direct" substitutes share identical electrical and mechanical specifications. Parts designated as "Similar" may include automotive AEC-Q200 certification or alternative RoHS/REACH compliance status, which do not prevent substitution but indicate application-specific qualifications.

Parameter Comparison

Engineering Selection Recommendations

Direct Substitutes (Electrically and Mechanically Equivalent):

CR0805-FX-1782ELF (Bourns Inc.), RC0805FR-0717K8L (YAGEO), ERJ-6ENF1782V (Panasonic Electronic Components), and RMCF0805FT17K8 (Stackpole Electronics Inc.) are direct substitutes for RC2012F1782CS. All maintain identical electrical specifications, ROHS3 compliance, and REACH unaffected status. These parts are suitable for direct replacement in applications where the original part is unavailable.

Application-Specific Alternatives:

ERJ-6ENF1782V and RMCF0805FT17K8 include automotive AEC-Q200 certification, qualifying them for automotive applications requiring this standard. CRCW080517K8FKEA (Vishay Dale) also carries AEC-Q200 certification with ROHS3 compliance and is suitable for automotive designs.

Compliance Consideration:

CRCW080517K8FKTA (Vishay Dale) is RoHS non-compliant and REACH affected. This part is not suitable for applications requiring ROHS3 compliance or REACH compliance and should not be selected as a substitute for RC2012F1782CS in regulated markets or applications with mandatory RoHS requirements.

Packaging Format:

The original RC2012F1782CS is supplied in Cut Tape (CT) format. All substitute parts are available in Tape & Reel (TR) format, which is standard for high-volume production and automated assembly. Packaging format does not affect electrical or mechanical compatibility.

Frequently Asked Questions (FAQ)

Q: Can CR0805-FX-1782ELF replace RC2012F1782CS in my circuit?

A: Yes. CR0805-FX-1782ELF is a direct substitute with identical resistance (17.8 kΩ), tolerance (±1%), power rating (0.125W), package (0805), temperature coefficient (±100ppm/°C), and operating temperature range (-55°C ~ 155°C). Both are ROHS3 compliant with MSL 1 rating.

Q: What is the difference between "Direct" and "Similar" substitute designations?

A: Direct substitutes match all electrical and mechanical parameters of the original part. Similar substitutes also match these parameters but include additional certifications (such as automotive AEC-Q200) or different compliance status. Similar substitutes are compatible but may be specified for particular application requirements.

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

A: Yes. Automotive-qualified parts such as ERJ-6ENF1782V and RMCF0805FT17K8 meet or exceed the specifications required for non-automotive applications. AEC-Q200 certification indicates enhanced reliability testing and is not restrictive for general-purpose use.

Q: Why is CRCW080517K8FKTA marked as RoHS non-compliant?

A: CRCW080517K8FKTA does not meet ROHS3 compliance requirements and is REACH affected. This part should not be used in applications or markets requiring RoHS compliance. Use CRCW080517K8FKEA (ROHS3 compliant variant) instead.

Q: Does the difference in maximum seated height affect PCB layout?

A: Seated height variations (0.50mm to 0.70mm) are within standard 0805 package tolerances and do not affect PCB layout, solder reflow profiles, or component placement. All listed parts are mechanically compatible with standard 0805 footprints.

Q: Can I use these substitutes in high-temperature applications?

A: Yes. All listed parts operate across the full temperature range of -55°C to 155°C with ±100ppm/°C temperature coefficient. They are suitable for applications requiring extended temperature operation within this range.

Q: What packaging format should I specify for production?

A: Tape & Reel (TR) format is standard for automated assembly and high-volume production. All substitute parts are available in TR format. Cut Tape (CT) format is typically used for manual assembly or low-volume prototyping.
