RC6432F1692CS Equivalent & Substitute Parts Reference

Part Overview

The RC6432F1692CS is a 16.9 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 a temperature coefficient of ±100ppm/°C. The part is currently in active production status with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Equivalent and substitute parts are identified to support procurement flexibility, inventory management, and supply chain continuity when the primary part becomes unavailable or when design requirements necessitate alternative sourcing options.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the RC6432F1692CS is determined by strict equivalence across the following critical parameters: resistance value (16.9 kOhms), tolerance (±1%), power rating (1W), package format (2512/6432 Metric), composition (thick film), temperature coefficient (±100ppm/°C), and operating temperature range (-55°C to 155°C). The substitute part CRCW251216K9FKEG manufactured by Vishay Dale meets all these electrical and mechanical specifications. Both parts share identical resistance, tolerance, power rating, package dimensions, composition type, and thermal characteristics. The substitute part includes automotive AEC-Q200 qualification, which represents an additional feature beyond the base specification. Dimensional variations within tolerance (length 6.30mm, width 3.15mm vs. 3.20mm, height 0.70mm vs. 0.66mm) remain within acceptable mechanical compatibility for standard PCB assembly processes. Both parts maintain ROHS3 compliance, unlimited MSL rating, and identical termination configuration.

Parameter Comparison

Engineering Selection Recommendations

The CRCW251216K9FKEG from Vishay Dale is a direct electrical and mechanical equivalent to the RC6432F1692CS. Both parts are active production components with ROHS3 compliance and identical core specifications. The Vishay Dale substitute carries AEC-Q200 automotive qualification, which provides additional reliability assurance for applications requiring automotive-grade components. Dimensional variations (width and height) fall within standard PCB assembly tolerances and do not impact footprint compatibility or reflow soldering processes. Selection between these parts should be based on availability, packaging format requirements (the substitute is supplied in Tape & Reel format), and whether automotive qualification is required for the application. Both parts maintain identical electrical performance across the specified operating temperature range and are suitable for direct substitution in circuit designs.

Frequently Asked Questions (FAQ)

Q: Can the CRCW251216K9FKEG replace the RC6432F1692CS in existing designs?

A: Yes. Both parts share identical electrical specifications (16.9 kOhms ±1%, 1W, ±100ppm/°C, -55°C to 155°C) and are packaged in the 2512 (6432 Metric) format. Dimensional variations are within standard PCB assembly tolerances.

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 qualification is an additional feature of the Vishay Dale part and does not affect compatibility with non-automotive applications.

Q: Are there packaging differences between these parts?

A: The main part (RC6432F1692CS) is listed with standard packaging, while the substitute (CRCW251216K9FKEG) is supplied in Tape & Reel (TR) format. Both are suitable for automated assembly processes.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the RC6432F1692CS and CRCW251216K9FKEG are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99. Both maintain MSL 1 (unlimited) moisture sensitivity rating.

Q: What are the acceptable dimensional tolerances for substitution?

A: The width difference (3.20mm vs. 3.15mm) and height difference (0.66mm vs. 0.70mm) are within standard component manufacturing tolerances and PCB design clearances. These variations do not affect mechanical fit or electrical performance.

Q: Can these parts be used interchangeably in high-temperature applications?

A: Yes. Both parts operate across the identical temperature range of -55°C to 155°C with the same temperature coefficient of ±100ppm/°C, ensuring equivalent performance in thermal cycling and high-temperature environments.
