Parameter Comparison

Engineering Selection Recommendations

The 4308R-101-332LF is a direct functional equivalent to the 4308R-101-332, with identical electrical performance and mechanical compatibility. The primary distinction is regulatory compliance: the 4308R-101-332LF carries ROHS3 certification, whereas the 4308R-101-332 is RoHS non-compliant. Both parts maintain REACH Affected status and EAR99 export classification.

Selection between these parts should be based on compliance requirements applicable to the end application. For designs requiring RoHS3 compliance, the 4308R-101-332LF is the appropriate choice. Both variants are active products from Bourns Inc. and are suitable for new designs.

Frequently Asked Questions (FAQ)

Q: Can the 4308R-101-332LF replace the 4308R-101-332 in existing designs?

A: Yes. The 4308R-101-332LF is electrically and mechanically identical to the 4308R-101-332. Both parts feature the same 3.3k Ohm resistance, ±2% tolerance, 7-resistor bussed configuration, 200mW power per element, and 8-SIP through-hole package. Direct substitution is possible without circuit modification.

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

A: The 4308R-101-332LF is ROHS3 compliant, while the 4308R-101-332 is RoHS non-compliant. All other specifications, including electrical performance, temperature range, and physical dimensions, are identical.

Q: Are there any package or pinout differences?

A: No. Both parts use the 8-SIP package with identical pinout, dimensions (0.784" L x 0.085" W), and maximum seated height (0.195"). Through-hole mounting compatibility is identical.

Q: Which part should be selected for new designs?

A: Selection depends on regulatory requirements. For applications requiring RoHS3 compliance, specify the 4308R-101-332LF. Both parts are active products suitable for new designs.

Q: Are there inventory considerations between these parts?

A: The 4308R-101-332LF has higher current inventory availability (4550 Pcs) compared to the 4308R-101-332 (1177 Pcs). Availability should be confirmed with your supplier for specific procurement timelines.
