Substitute Part Grouping Explanation

Substitution eligibility for the 4116R-1-122 resistor array is determined by strict equivalence across the following critical parameters:

• Resistance value: 1.2k Ohm
• Tolerance: ±2%
• Number of resistors: 8
• Circuit configuration: Isolated
• Power rating per element: 250mW
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C to 125°C
• Package: 16-DIP (0.300", 7.62mm)
• Pin count: 16
• Resistor-ratio-drift: 50ppm/°C

The 4116R-1-122LF variant meets all electrical and mechanical specifications identically to the main part number. The primary distinction lies in RoHS compliance status and packaging designation, which do not affect functional interchangeability in equivalent circuit applications.

Parameter Comparison

Engineering Selection Recommendations

Both the 4116R-1-122 and 4116R-1-122LF are active production components from Bourns Inc. with identical electrical and mechanical specifications. Selection between these part numbers should be based on regulatory and compliance requirements:

The 4116R-1-122LF is designated as ROHS3 compliant, making it the appropriate choice for applications subject to RoHS3 regulations or customer specifications requiring lead-free manufacturing processes. The 4116R-1-122 remains available for applications where RoHS compliance is not a requirement.

Both variants are REACH affected and classified under ECCN EAR99. Functional performance, thermal characteristics, and circuit compatibility are identical between the two part numbers.

Frequently Asked Questions (FAQ)

Q: Are the 4116R-1-122 and 4116R-1-122LF electrically interchangeable?

A: Yes. Both part numbers provide identical electrical performance, including resistance value, tolerance, temperature coefficient, and power rating. They are functionally equivalent in circuit applications.

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

A: The primary difference is RoHS compliance status. The 4116R-1-122LF is ROHS3 compliant, while the 4116R-1-122 is RoHS non-compliant. The "LF" designation typically indicates lead-free manufacturing. All other specifications are identical.

Q: Can I substitute the 4116R-1-122 with the 4116R-1-122LF in an existing design?

A: Yes, provided your application or customer requirements do not prohibit the use of RoHS non-compliant components. The 4116R-1-122LF is a direct functional substitute with no circuit modifications required.

Q: Are both parts available in the same package?

A: Yes. Both the 4116R-1-122 and 4116R-1-122LF are supplied in 16-DIP (0.300", 7.62mm) through-hole packages with identical physical dimensions and pin configurations.

Q: Which part should I specify for new designs?

A: For new designs, the 4116R-1-122LF is recommended due to its ROHS3 compliance status, which aligns with current regulatory standards and manufacturing practices. Specify the 4116R-1-122 only if RoHS non-compliant components are explicitly required.

Q: Do these parts have different temperature operating ranges?

A: No. Both parts operate across the identical temperature range of -55°C to 125°C with the same temperature coefficient of ±100ppm/°C.
