Bourns 4606X-102-470 Equivalent & Substitute Parts

Part Overview

The Bourns 4606X-102-470 is a 3-resistor isolated network array with 47 Ohm resistance, rated at 300mW per element, housed in a 6-SIP through-hole package. This component is classified as obsolete, making equivalent substitutes necessary for ongoing production and maintenance applications. The part operates across -55°C to 125°C with ±1 Ohm tolerance and ±250ppm/°C temperature coefficient.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 4606X-102-470 is determined by the following critical parameters: resistance value (47 Ohm), tolerance (±1 Ohm), number of resistors (3), power rating per element (300mW), temperature coefficient (±250ppm/°C), operating temperature range (-55°C to 125°C), circuit type (Isolated), pin count (6), package type (6-SIP), and through-hole mounting configuration.

The substitute parts are grouped into two categories:

Direct Substitute: 4606X-102-470LF matches all electrical and mechanical parameters identically, differing only in packaging format (Bulk vs. unspecified) and compliance status (RoHS3 Compliant vs. non-compliant).

Similar Substitutes: 4306R-102-470 and 4306R-102-470LF belong to the 4300R series and maintain all critical electrical parameters. Minor dimensional variations exist in physical size and height, with the 4306R series featuring a specified resistor-ratio-drift of 50ppm/°C compared to the unspecified drift in the 4606X series.

Parameter Comparison

Engineering Selection Recommendations

4606X-102-470LF is the primary direct substitute. It maintains identical electrical specifications and physical dimensions while offering active product status and RoHS3 compliance. Selection of this part eliminates obsolescence risk and aligns with modern regulatory requirements.

4306R-102-470LF is the recommended alternative when RoHS3 compliance is mandatory and minor dimensional variation is acceptable. This part offers active status and full compliance certification.

4306R-102-470 provides functional equivalence with active product status but does not meet RoHS3 compliance requirements. Selection is appropriate only when legacy compliance standards are specified.

4606X-102-470LF should be prioritized for new designs and production transitions due to its direct parameter alignment and compliance status.

Frequently Asked Questions (FAQ)

Q: Can 4606X-102-470LF directly replace 4606X-102-470 in existing designs?

A: Yes. The 4606X-102-470LF maintains identical electrical parameters, tolerance, power rating, temperature coefficient, and physical dimensions. The primary difference is active product status and RoHS3 compliance.

Q: What are the dimensional differences between 4606X and 4306R series parts?

A: The 4306R series has slightly smaller dimensions: 0.584" L x 0.085" W (14.83mm x 2.16mm) versus 0.598" L x 0.098" W (15.19mm x 2.49mm) for the 4606X series. Height also differs: 0.195" (4.95mm) for 4306R versus 0.200" (5.08mm) for 4606X. These variations may affect PCB layout and mechanical clearance.

Q: Are all substitute parts rated for the same temperature range?

A: Yes. All listed substitutes operate across -55°C to 125°C with ±250ppm/°C temperature coefficient.

Q: What is the significance of the "LF" suffix?

A: The "LF" designation indicates lead-free construction and RoHS3 compliance. Parts without this suffix use traditional lead-based solder and do not meet RoHS3 requirements.

Q: Does the 4306R series resistor-ratio-drift specification affect substitution?

A: The 4306R series specifies 50ppm/°C resistor-ratio-drift, while the 4606X series does not specify this parameter. Both maintain the same ±250ppm/°C temperature coefficient. Applications requiring specific resistor matching characteristics should evaluate this specification against design requirements.

Q: What packaging formats are available?

A: 4606X-102-470LF is supplied in Bulk packaging. 4306R-102-470 and 4306R-102-470LF are supplied in Tube packaging. Packaging selection affects order quantities and handling procedures.
