Key Parameters

Substitute Part Grouping Explanation

Substitution of the CMP1206AFX-47R0ELF is determined by strict equivalence across the following critical parameters:

Resistance value must be 47 Ohms with ±1% tolerance. Power rating must be 0.75W (3/4W). Package format must be 1206 (3216 Metric) to ensure mechanical and electrical compatibility with existing PCB layouts. Composition must be thick film. Temperature coefficient must be ±100ppm/°C. Operating temperature range must span -55°C to 155°C. All automotive and environmental features including anti-sulfur coating, AEC-Q200 qualification, moisture resistance, and pulse withstanding capability must be present. RoHS3 compliance and MSL 1 rating must be maintained. Substitute parts must originate from the same manufacturer (Bourns Inc.) to ensure consistency in manufacturing processes, quality control, and performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

The CHP1206AFX-47R0ELF is a direct parametric equivalent to the CMP1206AFX-47R0ELF. Both parts are manufactured by Bourns Inc. and share identical electrical specifications, mechanical dimensions, and environmental ratings. Both parts maintain Active product status and full compliance with RoHS3 and AEC-Q200 automotive standards. The primary distinction between the two parts is their series designation: CMP-A versus CHP-A. This series difference reflects internal Bourns manufacturing classifications but does not affect functional performance or compatibility in circuit applications.

Selection between CMP1206AFX-47R0ELF and CHP1206AFX-47R0ELF should be based on inventory availability and supply chain requirements. The CHP1206AFX-47R0ELF currently maintains higher inventory levels (11,430 pieces) compared to the CMP1206AFX-47R0ELF (664 pieces), making it the preferred choice for applications requiring immediate availability or large-volume procurement. Both parts are suitable for automotive, industrial, and high-reliability applications requiring thick film chip resistors with automotive-grade specifications.

Frequently Asked Questions (FAQ)

Q: Can CHP1206AFX-47R0ELF be used as a direct replacement for CMP1206AFX-47R0ELF in existing designs?

A: Yes. Both parts are parametrically identical across all critical electrical and mechanical specifications. The 1206 package format ensures identical PCB footprint compatibility. No design modifications are required for substitution.

Q: What is the difference between the CMP-A and CHP-A series designations?

A: The series designation reflects internal Bourns manufacturing classifications. Both series share identical performance characteristics, ratings, and compliance certifications. The series difference does not impact functional equivalence or circuit performance.

Q: Are both parts suitable for automotive applications?

A: Yes. Both CMP1206AFX-47R0ELF and CHP1206AFX-47R0ELF are AEC-Q200 qualified automotive-grade resistors. Both parts meet automotive reliability and environmental performance standards.

Q: What is the significance of the MSL 1 (Unlimited) moisture sensitivity rating?

A: MSL 1 indicates the lowest moisture sensitivity level. Parts with this rating have unlimited shelf life and do not require special moisture-controlled storage or handling procedures. Both substitute parts carry this rating.

Q: Are both parts RoHS3 compliant?

A: Yes. Both CMP1206AFX-47R0ELF and CHP1206AFX-47R0ELF are RoHS3 compliant, meeting current environmental and regulatory requirements for electronic components.

Q: Can these resistors be used in pulse withstanding applications?

A: Yes. Both parts feature pulse withstanding capability as part of their thick film construction and design specifications. This allows operation under transient overvoltage conditions within specified limits.

Q: What is the temperature coefficient significance for these parts?

A: The ±100ppm/°C temperature coefficient indicates the resistor's resistance change per degree Celsius across the -55°C to 155°C operating range. Both parts maintain identical temperature stability characteristics.
