Key Parameters

Substitute Part Grouping Explanation

Equivalent parts for the RC6432F7870CS are identified based on the following critical parameters that must match or be compatible:

• Resistance Value: 787 Ohms
• Tolerance: ±1%
• Power Rating: 1W
• Package / Case: 2512 (6432 Metric)
• Composition: Thick Film
• Temperature Coefficient: ±100ppm/°C
• Operating Temperature Range: -55°C ~ 155°C

Parts meeting these specifications are suitable substitutes. Secondary considerations include automotive qualification (AEC-Q200) and specific feature sets such as moisture resistance. Dimensional variations within the 2512 package specification are acceptable within standard tolerances.

Parameter Comparison

Engineering Selection Recommendations

All three parts meet the core electrical specifications for 787 Ohms ±1% 1W operation. Selection should prioritize product status and application requirements:

RC6432F7870CS is recommended as the primary choice due to Active product status and moisture-resistant feature set. This part remains in full production with unlimited availability.

CRCW2512787RFKEG serves as a direct equivalent with Active status and the additional benefit of automotive AEC-Q200 qualification. This is suitable for applications requiring automotive-grade components.

ERJ-1TNF7870U is electrically equivalent with AEC-Q200 qualification but carries a "Not For New Designs" status. Use this part only when existing designs require continuation of supply or when inventory constraints necessitate its use. New designs should avoid this part number.

Frequently Asked Questions (FAQ)

Q: Can I substitute RC6432F7870CS with CRCW2512787RFKEG? A: Yes. Both parts have identical resistance, tolerance, power rating, and package specifications. CRCW2512787RFKEG offers the additional benefit of AEC-Q200 automotive qualification.

Q: What is the difference between these 2512 packages? A: All three parts use the 2512 (6432 Metric) package with minor dimensional variations. The parts are physically similar with length ranging from 0.248" to 0.252" and width from 0.124" to 0.126", all within standard 2512 package tolerances.

Q: Is ERJ-1TNF7870U suitable for new designs? A: No. ERJ-1TNF7870U is marked as "Not For New Designs." This designation means Panasonic does not recommend this part for new product development. Use RC6432F7870CS or CRCW2512787RFKEG for new designs.

Q: Do all parts have the same temperature coefficient and operating range? A: Yes. All three parts specify ±100ppm/°C temperature coefficient and -55°C to 155°C operating temperature range.

Q: Are there packaging differences among these parts? A: RC6432F7870CS uses standard packaging. CRCW2512787RFKEG is supplied in Tape & Reel (TR) packaging. ERJ-1TNF7870U also uses Tape & Reel (TR) packaging. These are standard supply formats and compatible with automated assembly equipment.

Q: Why would I need a substitute part? A: Substitute parts may be required due to component availability fluctuations, lead time constraints, supply chain disruptions, or application-specific requirements such as automotive qualification.
