Bourns 4306R-101-680 Equivalent & Substitute Parts

Part Overview

The Bourns 4306R-101-680 is a 5-resistor network array with 68 Ohm resistance per element, rated at 200mW power dissipation per element. This through-hole mounted component operates across -55°C to 125°C and is designed for applications requiring bussed resistor configurations in a compact 6-SIP package. The part is currently active in production. Substitute parts are identified to address RoHS compliance requirements and inventory availability while maintaining identical electrical and mechanical specifications.

Substitute Part Grouping Explanation

Substitution for the 4306R-101-680 is based on strict equivalence across all electrical and mechanical parameters. The primary substitute, 4306R-101-680LF, maintains identical specifications for resistance value, tolerance, power rating, temperature coefficient, operating temperature range, circuit topology, package configuration, and physical dimensions. The key differentiator is RoHS compliance status: the 4306R-101-680LF is ROHS3 compliant, whereas the original part is RoHS non-compliant. Both parts share the same base product number (4306R), series designation (4300R), and are manufactured by Bourns Inc. Substitution is valid when RoHS3 compliance is required or when inventory availability of the compliant variant is preferred.

Parameter Comparison

Engineering Selection Recommendations

The 4306R-101-680LF is the direct substitute for the 4306R-101-680 when ROHS3 compliance is a design or procurement requirement. Both parts are active products from Bourns Inc. and are electrically and mechanically identical. Selection between the two parts depends on regulatory compliance mandates: applications subject to RoHS3 regulations must use the 4306R-101-680LF variant. For applications without RoHS compliance requirements, either part is functionally equivalent. Inventory availability should be considered as a secondary factor; the 4306R-101-680LF currently has higher stock levels (2339 pcs vs. 1127 pcs).

Frequently Asked Questions (FAQ)

Q: Can the 4306R-101-680LF be used as a direct replacement for the 4306R-101-680?

A: Yes. The 4306R-101-680LF is a direct electrical and mechanical equivalent. All resistance values, tolerances, power ratings, temperature coefficients, operating ranges, and package dimensions are identical. The only difference is RoHS compliance status.

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

A: The 4306R-101-680 is RoHS non-compliant, while the 4306R-101-680LF is ROHS3 compliant. The "LF" suffix typically indicates lead-free construction. All other specifications are identical.

Q: Are there any pin configuration differences between these parts?

A: No. Both parts use the same 6-SIP package with 6 pins and identical physical dimensions (0.584" L x 0.085" W, height 0.195" max). PCB layout and footprints are interchangeable.

Q: What applications are these resistor arrays suitable for?

A: These 68 Ohm, 200mW per element bussed resistor networks are used in general-purpose circuit applications requiring multiple matched resistors in a compact through-hole package. The ±2% tolerance and ±100ppm/°C temperature coefficient support precision analog and digital circuits operating across -55°C to 125°C.

Q: Can I mix these parts in the same design or production run?

A: Yes, provided your design does not mandate RoHS compliance. If RoHS3 compliance is required, use only the 4306R-101-680LF. If no compliance requirement exists, both parts are functionally equivalent and can be used interchangeably.
