Parameter Comparison

Engineering Selection Recommendations

The CHP1206AFX-1003ELF is a direct equivalent substitute for the CMP1206AFX-1003ELF. Both parts are manufactured by Bourns Inc. and maintain identical electrical, mechanical, and compliance specifications. The primary difference between the two parts is the series designation: CMP-A series versus CHP-A series. Both parts carry active product status and full AEC-Q200 automotive qualification.

Selection between CMP1206AFX-1003ELF and CHP1206AFX-1003ELF is determined by availability and inventory requirements. The CHP1206AFX-1003ELF currently has 5408 units in stock compared to 4530 units for the CMP1206AFX-1003ELF. Both parts are ROHS3 compliant, REACH unaffected, and carry MSL 1 moisture sensitivity rating, indicating unlimited shelf life under standard storage conditions.

For applications requiring 100 kOhms ±1% resistance in 1206 package format with 0.75W power dissipation capability and automotive-grade environmental protection, either part number provides equivalent performance and reliability.

Frequently Asked Questions (FAQ)

Q: Can CHP1206AFX-1003ELF be used as a direct replacement for CMP1206AFX-1003ELF?

A: Yes. Both parts are manufactured by Bourns Inc. and maintain identical electrical specifications (100 kOhms ±1%, 0.75W), mechanical dimensions (1206 package, 3.10mm x 1.60mm), and compliance certifications (AEC-Q200, ROHS3, MSL 1). The parts are directly interchangeable in circuit applications.

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

A: The series designation indicates different product lines within Bourns Inc.'s automotive resistor portfolio. Both series meet identical electrical and environmental specifications for this 100 kOhms ±1% 0.75W application. The series difference does not affect functional performance or compatibility.

Q: Are both parts suitable for automotive applications?

A: Yes. Both CMP1206AFX-1003ELF and CHP1206AFX-1003ELF carry AEC-Q200 automotive qualification, anti-sulfur coating, moisture resistance, and pulse withstanding capability. Both parts are rated for -55°C to 155°C operating temperature range, meeting automotive environmental requirements.

Q: What does MSL 1 (Unlimited) moisture sensitivity rating mean?

A: MSL 1 indicates the lowest moisture sensitivity level. Components with MSL 1 rating have unlimited shelf life under standard storage conditions and do not require special moisture-control packaging or baking procedures prior to soldering.

Q: Are there any packaging differences between the two part numbers?

A: No. Both parts are supplied in Tape & Reel (TR) packaging format. Physical dimensions, height, and termination count are identical across both part numbers.

Q: What compliance certifications apply to both parts?

A: Both parts are ROHS3 compliant and REACH unaffected. Both carry AEC-Q200 automotive qualification. ECCN classification is EAR99 for both parts, and HTSUS code is 8533.21.0030.
