Parameter Comparison

Engineering Selection Recommendations

The CHP1206AFX-1001ELF serves as a direct equivalent substitute for the CMP1206AFX-1001ELF. Both parts are manufactured by Bourns Inc. and share identical electrical, mechanical, and compliance specifications. Selection between these parts is based on availability and supply chain requirements rather than technical differentiation.

Both parts maintain Active product status and full compliance with automotive AEC-Q200 qualification, RoHS3 directives, and REACH regulations. The identical temperature coefficient, operating temperature range, and MSL 1 rating ensure interchangeability in automotive and industrial applications requiring high-reliability thick film resistors.

The CHP-A series designation indicates the substitute part belongs to an alternative product line within Bourns' high-power resistor portfolio, while maintaining complete functional and mechanical compatibility with the CMP-A series.

Frequently Asked Questions (FAQ)

Q: Can CHP1206AFX-1001ELF be used as a direct replacement for CMP1206AFX-1001ELF?

A: Yes. Both parts are electrically and mechanically identical with matching resistance values (1 kOhms ±1%), power ratings (0.75W), package dimensions (1206/3216 Metric), temperature coefficients (±100ppm/°C), and operating ranges (-55°C to 155°C). Both carry AEC-Q200 automotive qualification and RoHS3 compliance.

Q: Are there any differences in automotive qualification between these parts?

A: No. Both CMP1206AFX-1001ELF and CHP1206AFX-1001ELF carry identical AEC-Q200 ratings, making them suitable for automotive applications without qualification restrictions.

Q: What is the significance of the series designation change from CMP-A to CHP-A?

A: The series designation indicates different product lines within Bourns' manufacturing portfolio. However, this designation change does not affect electrical performance, mechanical compatibility, or compliance certifications. Both series maintain identical specifications for this 1 kOhms ±1% 0.75W resistor.

Q: Are the physical dimensions identical for PCB placement?

A: Yes. Both parts share identical 1206 (3216 Metric) package dimensions: 0.122" L x 0.063" W (3.10mm x 1.60mm) with maximum seated height of 0.026" (0.65mm). PCB footprints and placement requirements are identical.

Q: Do both parts have the same moisture sensitivity rating?

A: Yes. Both parts carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions for storage, handling, or reflow processes.

Q: What features are common to both substitute parts?

A: Both parts include anti-sulfur coating, moisture resistance, and pulse withstanding capability. These features are standard across both the CMP-A and CHP-A series for this resistance and power rating combination.
