Substitute Part Grouping Explanation

Substitution eligibility for the 4306R-101-203 is determined by strict equivalence across the following critical parameters:

• Resistance value: 20kΩ
• Tolerance: ±2%
• Number of resistor elements: 5
• Power rating per element: 200mW
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C to 125°C
• Circuit configuration: Bussed topology
• Package designation: 6-SIP
• Mounting technology: Through hole
• Pin count: 6
• Physical footprint: 0.584" L × 0.085" W

The identified substitute part maintains full electrical and mechanical compatibility with the original specification. Differences in RoHS compliance status and inventory availability do not affect functional interchangeability.

Parameter Comparison

Engineering Selection Recommendations

Both the 4306R-101-203 and 4306R-101-203LF are active production parts from Bourns Inc. with identical electrical and mechanical specifications. Selection between these parts should be based on regulatory and compliance requirements:

The 4306R-101-203LF carries ROHS3 compliance certification, making it the appropriate choice for applications subject to RoHS directives or customer specifications requiring lead-free component qualification. The original 4306R-101-203 is RoHS non-compliant and should be selected only when legacy compliance status is explicitly required or when RoHS compliance is not a project constraint.

Both parts are REACH Affected and carry the same ECCN (EAR99) and HTSUS (8533.21.0050) classifications. Inventory availability differs, with the 4306R-101-203LF currently showing higher stock levels (2275 pcs vs. 941 pcs).

Frequently Asked Questions (FAQ)

Q: Are the 4306R-101-203 and 4306R-101-203LF electrically interchangeable?

A: Yes. Both parts have identical resistance values (20kΩ), tolerance (±2%), power ratings (200mW per element), temperature coefficients (±100ppm/°C), and operating temperature ranges (-55°C to 125°C). They are direct electrical equivalents.

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

A: The primary difference is RoHS compliance status. The 4306R-101-203LF is ROHS3 compliant (lead-free), while the 4306R-101-203 is RoHS non-compliant. All other electrical and mechanical parameters are identical.

Q: Can I use the 4306R-101-203LF as a drop-in replacement for the 4306R-101-203?

A: Yes, from an electrical and mechanical standpoint. The 6-SIP package, pin configuration, footprint, and all performance characteristics are identical. Verify that your application or customer requirements do not mandate the non-compliant version.

Q: Are there any package or mounting differences?

A: No. Both parts use the 6-SIP through-hole package with identical physical dimensions (0.584" L × 0.085" W, 14.83mm × 2.16mm) and seated height (0.195" / 4.95mm). PCB layout and assembly procedures are identical.

Q: Which part should I specify for new designs?

A: Specify the 4306R-101-203LF for new designs unless legacy compliance requirements explicitly mandate the non-compliant version. The ROHS3 compliant variant aligns with current industry standards and regulatory expectations.
