RC6432F182CS Equivalent & Substitute Parts Reference

Part Overview

The RC6432F182CS is a 1.8 kOhms ±1% 1W chip resistor manufactured by Samsung Electro-Mechanics in the 2512 (6432 Metric) package format. This thick film, moisture-resistant component operates across the temperature range of -55°C to 155°C and maintains ROHS3 compliance with unlimited moisture sensitivity rating (MSL 1). The part is currently in active production status with 1110 units available in new original inventory. Equivalent and substitute parts are identified when they maintain identical or functionally compatible electrical specifications, mechanical dimensions, and regulatory compliance within the 2512 package category.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RC6432F182CS are identified based on strict equivalence across the following critical parameters:

Electrical Equivalence Requirements:

• Resistance value: 1.8 kOhms (exact match)
• Tolerance: ±1% (exact match)
• Power rating: 1W (exact match)
• Temperature coefficient: ±100ppm/°C (exact match)
• Operating temperature range: -55°C ~ 155°C (exact match)

Mechanical Equivalence Requirements:

• Package format: 2512 (6432 Metric) (exact match)
• Number of terminations: 2 (exact match)
• Composition: Thick Film (exact match)

Compliance Equivalence Requirements:

• RoHS Status: ROHS3 Compliant (exact match)
• Moisture Sensitivity Level: 1 (Unlimited) (exact match)
• REACH Status: REACH Unaffected (exact match)

The CRCW25121K80FKEG from Vishay Dale meets all electrical, mechanical, and compliance criteria for direct substitution. The primary distinction is the inclusion of AEC-Q200 automotive qualification in the substitute part, which represents an additional certification level rather than a deviation from base specifications.

Parameter Comparison

Engineering Selection Recommendations

The CRCW25121K80FKEG qualifies as a direct electrical and mechanical substitute for the RC6432F182CS based on complete parameter equivalence across all critical specifications. Both components maintain identical resistance, tolerance, power rating, temperature coefficient, and operating temperature range. Package dimensions are compatible within standard PCB assembly tolerances, with minor variations in width (0.126" vs 0.124") and height (0.026" vs 0.028") that do not affect board-level integration.

Both parts maintain ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1), ensuring equivalent environmental performance and handling requirements. The CRCW25121K80FKEG includes AEC-Q200 automotive qualification, which provides additional reliability assurance for applications requiring automotive-grade components. This qualification does not restrict use in non-automotive applications and represents a superset of standard thick film resistor performance criteria.

Selection between these parts should be based on availability, lead time, packaging format requirements (the substitute is supplied in Tape & Reel format), and any application-specific qualification requirements. Both parts are in active production with substantial inventory availability.

Frequently Asked Questions (FAQ)

Q: Can the CRCW25121K80FKEG replace the RC6432F182CS in existing designs without PCB modification?

A: Yes. Both components use the 2512 (6432 Metric) package with compatible mechanical dimensions. The dimensional variations (width difference of 0.002" and height difference of 0.002") fall within standard PCB assembly tolerances and do not require design changes.

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

A: AEC-Q200 is an automotive industry standard qualification that certifies component reliability under automotive operating conditions. This certification does not restrict the part to automotive applications and indicates enhanced quality assurance. Non-automotive applications benefit from this additional qualification level.

Q: Are the electrical specifications identical between these two parts?

A: Yes. Both parts specify 1.8 kOhms resistance with ±1% tolerance, 1W power rating, ±100ppm/°C temperature coefficient, and -55°C to 155°C operating temperature range. Electrical performance is equivalent.

Q: What is the difference in packaging between these parts?

A: The RC6432F182CS is supplied in standard packaging format, while the CRCW25121K80FKEG is supplied in Tape & Reel (TR) format. Tape & Reel packaging is standard for automated assembly processes and does not affect component performance.

Q: Do both parts meet the same compliance requirements?

A: Yes. Both components are ROHS3 compliant, REACH unaffected, and carry MSL 1 (unlimited) moisture sensitivity rating. Regulatory and environmental compliance is equivalent.

Q: Are there any restrictions on substituting the Vishay part for the Samsung part?

A: No restrictions exist based on the provided specifications. Both parts are in active production status with identical electrical, mechanical, and compliance characteristics. Selection should be based on availability, lead time, and packaging format requirements.
