Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RC6432F161CS are identified through strict matching of the following critical parameters:

• Resistance Value: 160 Ohms (exact match required)
• Tolerance: ±1% (exact match required)
• Power Rating: 1W (exact match required)
• Package Dimensions: 2512 (6432 Metric) with compatible physical dimensions
• Composition: Thick Film construction
• Temperature Coefficient: ±100ppm/°C (exact match required)
• Operating Temperature Range: -55°C ~ 155°C (exact match required)
• Compliance: ROHS3 Compliant, REACH Unaffected

Substitution is valid when all electrical parameters and package specifications align with these criteria. Physical dimensions including length, width, and maximum seated height must be compatible with PCB layout and assembly equipment specifications.

Parameter Comparison

Engineering Selection Recommendations

The RMCF2512FT160R from Stackpole Electronics Inc is a direct electrical equivalent to the RC6432F161CS. Both components meet ROHS3 compliance and REACH requirements, confirming regulatory alignment for industrial and commercial applications.

The primary distinction between these parts is the inclusion of AEC-Q200 automotive qualification in the RMCF2512FT160R. This certification indicates the Stackpole component has undergone additional reliability testing and qualification for automotive-grade applications. The RC6432F161CS, while meeting general industrial specifications, does not carry this automotive designation.

Physical dimensions are compatible with a maximum seated height difference of 0.002" (0.04mm), which falls within standard PCB assembly tolerances. Packaging format differs: the RC6432F161CS is supplied in bulk format, while the RMCF2512FT160R is supplied in Tape & Reel format, affecting procurement and assembly workflow considerations.

Selection between these parts should be based on application requirements: use the RC6432F161CS for general industrial applications where automotive qualification is not required, or select the RMCF2512FT160R when AEC-Q200 compliance is specified or preferred for enhanced reliability assurance.

Frequently Asked Questions (FAQ)

Q: Can the RMCF2512FT160R replace the RC6432F161CS in any circuit application?

A: The RMCF2512FT160R is electrically equivalent to the RC6432F161CS across all specified parameters: resistance value, tolerance, power rating, temperature coefficient, and operating temperature range. Direct substitution is valid from an electrical standpoint. The AEC-Q200 automotive qualification of the Stackpole part provides additional reliability assurance but does not restrict its use in non-automotive applications.

Q: What is the significance of the AEC-Q200 rating on the RMCF2512FT160R?

A: AEC-Q200 is an automotive industry standard qualification that certifies the component has passed rigorous reliability testing including thermal cycling, moisture resistance, and long-term stability evaluation. This certification is relevant for automotive and high-reliability applications but is not required for general industrial use.

Q: Are there physical dimension compatibility concerns when substituting these parts?

A: Both components share identical length and width dimensions of 0.248" L x 0.126" W (6.30mm x 3.20mm). The maximum seated height differs by 0.002" (0.04mm), which is within standard PCB assembly tolerances and does not present compatibility issues for typical circuit board layouts.

Q: How does packaging format affect component selection?

A: The RC6432F161CS is supplied in bulk packaging, while the RMCF2512FT160R is supplied in Tape & Reel format. Tape & Reel packaging is optimized for automated assembly processes and high-volume production. Bulk packaging is suitable for manual assembly or lower-volume applications. Selection should align with your assembly process capabilities and procurement requirements.

Q: Are both parts compliant with environmental and regulatory standards?

A: Both the RC6432F161CS and RMCF2512FT160R are ROHS3 Compliant and REACH Unaffected, confirming compliance with current environmental and hazardous substance regulations applicable to electronic components in industrial markets.
