Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RC6432F8253CS are identified based on strict electrical and mechanical parameter alignment. The substitution criteria are:

Primary Electrical Parameters:

• Resistance value: 825 kOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Power rating: 1W (exact match required)
• Temperature coefficient: ±100ppm/°C (exact match required)
• Operating temperature range: -55°C ~ 155°C (exact match required)

Mechanical Parameters:

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

Compliance Parameters:

• RoHS Status: ROHS3 Compliant (minimum requirement)
• Moisture Sensitivity Level: 1 (Unlimited) (minimum requirement)

The CRCW2512825KFKEG manufactured by Vishay Dale meets all substitution criteria and qualifies as a direct equivalent.

Parameter Comparison

Engineering Selection Recommendations

The CRCW2512825KFKEG from Vishay Dale is a qualified substitute for the RC6432F8253CS. Both components share identical electrical specifications, package format, and compliance certifications. The dimensional variations (width difference of 0.01" and height difference of 0.002") fall within acceptable mechanical tolerances for 2512 package footprints and do not affect PCB assembly compatibility.

Both parts maintain Active product status and ROHS3 compliance. The Vishay Dale component includes AEC-Q200 automotive qualification, which provides additional reliability assurance beyond the base specification requirements. Selection between these parts should be based on availability, lead time, packaging format requirements (the Vishay part is supplied in Tape & Reel format), and project-specific sourcing preferences.

Frequently Asked Questions (FAQ)

Q: Can the CRCW2512825KFKEG replace the RC6432F8253CS in existing designs?

A: Yes. Both components meet identical electrical specifications (825 kOhms ±1%, 1W, ±100ppm/°C, -55°C to 155°C operating range) and use the same 2512 (6432 Metric) package format. Mechanical dimensions are compatible within standard PCB assembly tolerances.

Q: What are the key differences between these two parts?

A: The primary differences are manufacturer identity and packaging format. The Samsung part is supplied in standard packaging, while the Vishay Dale part is supplied in Tape & Reel (TR) format. The Vishay component includes AEC-Q200 automotive qualification. Dimensional variations are minor and do not affect circuit performance or PCB compatibility.

Q: Are there any compliance or certification differences?

A: Both parts are ROHS3 compliant, REACH unaffected, and classified as EAR99 for export control. Both maintain MSL 1 (Unlimited) moisture sensitivity level. The Vishay Dale component carries additional AEC-Q200 automotive qualification.

Q: What packaging formats are available?

A: The RC6432F8253CS is available in standard packaging. The CRCW2512825KFKEG is supplied in Tape & Reel (TR) format, which is standard for high-volume manufacturing and automated assembly processes.

Q: Are the physical dimensions identical?

A: Dimensions are compatible but not identical. Length is the same (0.248" / 6.30mm). Width differs by 0.01" (3.20mm vs 3.15mm), and seated height differs by 0.002" (0.66mm vs 0.70mm). These variations are within standard 2512 package tolerances and do not affect PCB footprint compatibility.

Q: Can I use either part interchangeably in my circuit?

A: Yes. Electrical performance, thermal characteristics, and reliability are equivalent. Component selection should be based on availability, packaging requirements, and sourcing logistics.
