Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 4116R-1-183 is determined by the following critical parameters:

• Resistance value: 18kΩ (exact match required)
• Tolerance: ±2% (exact match required)
• Number of resistors: 8 (exact match required)
• Circuit type: Isolated (exact match required)
• Power per element: 250mW (exact match required)
• Temperature coefficient: ±100ppm/°C (exact match required)
• Package: 16-DIP (0.300", 7.62mm) (exact match required)
• Operating temperature range: -55°C to 125°C (exact match required)

The 4116R-1-183LF qualifies as a direct substitute because it maintains identical electrical specifications and mechanical packaging. The primary distinction is the RoHS compliance status and lead-free termination designation (LF suffix).

Parameter Comparison

Engineering Selection Recommendations

The 4116R-1-183LF is a direct functional equivalent to the 4116R-1-183. Selection between these parts should be based on compliance requirements:

• Use 4116R-1-183LF for applications requiring ROHS3 compliance or lead-free termination specifications.
• Use 4116R-1-183 where RoHS compliance is not a requirement and standard lead-based termination is acceptable.

Both parts share identical electrical performance, thermal characteristics, and mechanical compatibility. The choice between them is determined by regulatory or procurement specifications rather than technical performance differences.

Frequently Asked Questions (FAQ)

Q: Can the 4116R-1-183LF be used as a direct replacement for the 4116R-1-183?

A: Yes. The 4116R-1-183LF is electrically and mechanically identical to the 4116R-1-183. The LF designation indicates lead-free termination and ROHS3 compliance. Both parts have identical resistance values, tolerances, power ratings, temperature coefficients, and package dimensions.

Q: What is the difference between the 4116R-1-183 and 4116R-1-183LF?

A: The primary difference is RoHS compliance status. The 4116R-1-183LF is ROHS3 compliant with lead-free termination, while the 4116R-1-183 is RoHS non-compliant with standard lead-based termination. All electrical and mechanical specifications are identical.

Q: Are these parts pin-compatible?

A: Yes. Both the 4116R-1-183 and 4116R-1-183LF use the same 16-DIP package with identical pin configuration, spacing, and layout. They are fully interchangeable at the PCB level.

Q: What applications are these resistor arrays suitable for?

A: These 8-resistor isolated networks are used in applications requiring multiple matched resistors with stable temperature performance. The 18kΩ value and ±100ppm/°C temperature coefficient make them suitable for precision analog circuits, signal conditioning, and impedance matching applications.

Q: Can I substitute these parts with resistor arrays from other manufacturers?

A: Substitution with parts from other manufacturers requires verification that the alternative part maintains identical specifications across all critical parameters: 18kΩ resistance, ±2% tolerance, 8 isolated resistors, 250mW per element, ±100ppm/°C temperature coefficient, 16-DIP package, and -55°C to 125°C operating range.
