Substitute Part Grouping Explanation

Substitution eligibility for the 4306R-101-271 is determined by strict equivalence across the following critical parameters:

• Resistance value: 270 Ohm
• Tolerance: ±2%
• Number of resistors: 5
• Circuit configuration: Bussed
• Power rating per element: 200mW
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C to 125°C
• Package designation: 6-SIP
• Mounting technology: Through Hole
• Physical footprint and pin count: 6 pins

The identified substitute part maintains full electrical and mechanical compatibility with the original specification. Differences in RoHS compliance status and packaging variants (tube) do not affect functional substitutability.

Parameter Comparison

Engineering Selection Recommendations

The 4306R-101-271LF serves as a direct electrical and mechanical substitute for the 4306R-101-271. Both parts are manufactured by Bourns Inc. and maintain identical electrical specifications, package geometry, and pin configuration.

The primary distinction between these parts is RoHS compliance status. The 4306R-101-271LF carries ROHS3 compliance certification, while the 4306R-101-271 is RoHS non-compliant. Selection between these parts should be based on regulatory requirements applicable to the end application and target market. Both parts remain subject to REACH regulations.

Both parts are active products with confirmed inventory availability. Functional performance, thermal characteristics, and mechanical compatibility are equivalent across all specified operating conditions.

Frequently Asked Questions (FAQ)

Q: Can the 4306R-101-271LF replace the 4306R-101-271 in existing designs?

A: Yes. The 4306R-101-271LF is electrically and mechanically equivalent. All resistance values, tolerances, power ratings, temperature coefficients, and package dimensions are identical. Direct substitution is possible without circuit modification.

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

A: The primary difference is RoHS compliance status. The 4306R-101-271LF is ROHS3 compliant, while the 4306R-101-271 is not. Both parts are manufactured by Bourns Inc. and share identical electrical and mechanical specifications.

Q: Are there any thermal or performance differences between these parts?

A: No. Both parts operate across -55°C to 125°C with identical temperature coefficients of ±100ppm/°C and power ratings of 200mW per element. Thermal and electrical performance is equivalent.

Q: Does the RoHS compliance status affect circuit performance?

A: No. RoHS compliance relates to material composition and regulatory adherence, not electrical function. Both parts deliver identical circuit performance.

Q: Can these parts be used interchangeably on the same PCB?

A: Yes. Both parts use the 6-SIP through-hole package with identical pin configuration, footprint dimensions (0.584" L x 0.085" W), and height (0.195" max). PCB layouts require no modification for substitution.

Q: Which part should be selected for new designs?

A: Selection depends on regulatory requirements. For applications requiring RoHS3 compliance, use 4306R-101-271LF. For applications without RoHS compliance mandates, either part is suitable based on availability and cost considerations.
