• Circuit configuration: Bussed
• Power per element: 80mW
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C to 125°C
• Package: 14-SOIC (0.220", 5.59mm Width)
• Pin count: 14
• Mounting type: Surface Mount
• Series: 4800P

The identified substitute part maintains identical electrical and mechanical specifications. Differences in RoHS compliance status and REACH classification do not affect functional interchangeability but may impact supply chain and regulatory requirements for specific end applications.

Parameter Comparison

Engineering Selection Recommendations

Both the 4814P-2-103 and 4814P-2-103LF are active products from Bourns Inc. with identical electrical and mechanical specifications. Selection between these parts is determined by regulatory and compliance requirements:

The 4814P-2-103LF is ROHS3 compliant and REACH unaffected, making it suitable for applications subject to European Union environmental directives and regulations. The 4814P-2-103 is RoHS non-compliant and REACH affected, appropriate for applications without such regulatory constraints or where legacy component specifications are required.

Both parts maintain AEC-Q200 automotive qualification and are suitable for the full operating temperature range of -55°C to 125°C. Inventory availability and supply chain considerations may also influence part selection.

Frequently Asked Questions (FAQ)

Q: Are the 4814P-2-103 and 4814P-2-103LF electrically interchangeable?

A: Yes. Both parts have identical resistance values (10kΩ), tolerance (±2%), power ratings (80mW per element), temperature coefficients (±100ppm/°C), and operating temperature ranges (-55°C to 125°C). They are functionally equivalent in all electrical parameters.

Q: Are the packages physically identical?

A: Yes. Both parts use the 14-SOIC package with identical dimensions: 0.390" L x 0.220" W (9.91mm x 5.59mm) and maximum seated height of 0.094" (2.40mm). PCB layout and assembly processes require no modification when substituting between these parts.

Q: What is the difference between these two part numbers?

A: The primary differences are compliance certifications. The 4814P-2-103LF is ROHS3 compliant and REACH unaffected, while the 4814P-2-103 is RoHS non-compliant and REACH affected. Both are active products with identical technical specifications.

Q: Which part should I select for new designs?

A: Selection depends on regulatory requirements for your application. For applications subject to EU environmental regulations, select the 4814P-2-103LF. For applications without such constraints, either part is suitable based on availability and cost considerations.

Q: Are both parts suitable for automotive applications?

A: Yes. Both parts carry AEC-Q200 automotive qualification and are rated for the full automotive temperature range of -55°C to 125°C.
