Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the CMP1206AFX-1002ELF are identified through parametric equivalence matching. The substitution logic is based on the following critical parameters that must remain identical:

• Resistance Value: 10 kOhms
• Tolerance: ±1%
• Power Rating: 0.75W (3/4W)
• Package Designation: 1206 (3216 Metric)
• Physical Dimensions: 0.122" L x 0.063" W (3.10mm x 1.60mm), Height 0.026" (0.65mm) maximum
• Composition: Thick Film
• Temperature Coefficient: ±100ppm/°C
• Operating Temperature Range: -55°C ~ 155°C
• Automotive Qualification: AEC-Q200
• Environmental Features: Anti-Sulfur, Moisture Resistant, Pulse Withstanding
• Compliance: ROHS3 Compliant, REACH Unaffected

Parts meeting all these parameters are classified as parametric equivalents and direct substitutes. Series designation differences (CMP-A versus CHP-A) do not affect functional equivalence when all electrical and mechanical specifications are identical.

Parameter Comparison

Engineering Selection Recommendations

The CHP1206AFX-1002ELF is a direct parametric equivalent to the CMP1206AFX-1002ELF. Both parts are manufactured by Bourns Inc. and share identical electrical specifications, mechanical dimensions, and compliance certifications. The parts differ only in series designation (CMP-A versus CHP-A), which reflects internal product line organization and does not impact functional performance or interchangeability.

Both parts maintain active product status and full compliance with ROHS3 and REACH requirements. The AEC-Q200 automotive qualification is present on both parts, confirming suitability for automotive and high-reliability applications. The identical temperature coefficient (±100ppm/°C), operating temperature range (-55°C ~ 155°C), and environmental protection features (anti-sulfur, moisture resistant, pulse withstanding) ensure equivalent performance in circuit applications.

Selection between these parts may be based on inventory availability, supply chain considerations, or procurement preferences, as no technical differentiation exists between them.
