Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RC6432F681CS are classified into three categories based on electrical and mechanical compatibility:

Direct Equivalent (RC2512FK-07680RL): Identical electrical specifications (680 Ohms, ±1%, 1W) and mechanical package (2512). Manufactured by YAGEO with matching temperature coefficient (±100ppm/°C), operating temperature range (-55°C ~ 155°C), and moisture resistance features. Differs only in packaging format (Cut Tape & Digi-Reel vs. standard packaging) and minor dimensional tolerances within acceptable limits.

Upgrade Substitutes: Parts that exceed or enhance the original specification while maintaining full compatibility:

• AC2512FK-07680RL: Adds automotive AEC-Q200 qualification to the standard 1W specification
• RHC2512FT680R: Increases power rating to 2W while maintaining all other electrical parameters

Similar Substitutes: Parts with matching core electrical specifications but featuring automotive AEC-Q200 qualification:

• CRCW2512680RFKEG (Vishay Dale)
• RMCF2512FT680R (Stackpole Electronics Inc)

All substitute parts maintain the critical parameters: 680 Ohms resistance, ±1% tolerance, 2512 package, thick film composition, ±100ppm/°C temperature coefficient, -55°C ~ 155°C operating range, MSL 1, and RoHS3 compliance.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement: RC2512FK-07680RL (YAGEO) provides identical electrical and mechanical specifications with equivalent product status and compliance certifications. This part is suitable for applications requiring no additional qualification beyond the original design parameters.

For Automotive Applications: AC2512FK-07680RL (YAGEO), CRCW2512680RFKEG (Vishay Dale), and RMCF2512FT680R (Stackpole Electronics Inc) incorporate AEC-Q200 automotive qualification. These parts are appropriate for designs requiring automotive-grade component reliability and qualification documentation.

For Increased Power Margin: RHC2512FT680R (Stackpole Electronics Inc) provides 2W power rating while maintaining all other electrical parameters. This upgrade is applicable in designs where thermal margin or power dissipation headroom is required without circuit redesign.

All substitute parts maintain RoHS3 compliance, MSL 1 rating, and the specified operating temperature range (-55°C ~ 155°C), ensuring compatibility with existing environmental and regulatory requirements.

Frequently Asked Questions (FAQ)

Q: Can RC2512FK-07680RL be used as a direct replacement for RC6432F681CS?

A: Yes. Both parts share identical electrical specifications (680 Ohms, ±1%, 1W), mechanical package (2512), temperature coefficient (±100ppm/°C), operating temperature range (-55°C ~ 155°C), and compliance certifications (RoHS3, MSL 1). The parts differ only in packaging format and minor dimensional tolerances within acceptable limits.

Q: What is the difference between the 1W and 2W versions?

A: RHC2512FT680R provides 2W power rating compared to the 1W rating of RC6432F681CS. All other electrical parameters remain identical. The 2W version is suitable for applications requiring higher power dissipation capability in the same package footprint.

Q: Are the automotive-qualified parts (AC2512FK-07680RL, CRCW2512680RFKEG, RMCF2512FT680R) interchangeable with the standard version?

A: Yes, from an electrical and mechanical standpoint. Automotive-qualified parts meet AEC-Q200 standards and are fully compatible with designs using standard industrial-grade resistors. The automotive qualification provides additional reliability documentation and testing verification suitable for automotive applications.

Q: Do all substitute parts have the same package dimensions?

A: All parts use the 2512 (6432 Metric) package. Minor dimensional variations exist within manufacturing tolerances: RC6432F681CS measures 0.248" L x 0.126" W (6.30mm x 3.20mm), while YAGEO parts measure 0.250" L x 0.122" W (6.35mm x 3.10mm). These variations are within standard PCB footprint tolerances and do not affect mechanical compatibility.

Q: What is the moisture sensitivity level (MSL) and why is it important?

A: All listed parts carry MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. These components can be stored and handled without special moisture control measures, simplifying supply chain management and manufacturing processes.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All substitute parts listed carry RoHS3 compliance certification, matching the environmental and regulatory requirements of the original RC6432F681CS component.
