Equivalent & Substitute Parts for 4606X-101-331

Part Overview

The Bourns 4606X-101-331 is a 5-resistor network array with 330 Ohm resistance, ±2% tolerance, and 200mW power per element in a 6-SIP through-hole package. This part is classified as obsolete, making equivalent substitutes necessary for new designs and production continuity. The 4600X series has been superseded by newer product lines while maintaining electrical and mechanical compatibility with qualified alternatives.

Substitute Part Grouping Explanation

Substitution eligibility is determined by matching the following critical parameters: resistance value (330 Ohm), tolerance (±2%), number of resistors (5), circuit topology (bussed), power rating (200mW per element), temperature coefficient (±100ppm/°C), operating temperature range (-55°C to 125°C), pin count (6), and package form factor (6-SIP through-hole). Dimensional variations within the 6-SIP envelope are acceptable provided the package footprint remains compatible with existing PCB layouts.

The substitute parts are grouped into two categories:

Direct Bourns Equivalents: Parts from the same manufacturer with identical electrical specifications and active product status, differing only in packaging format or RoHS compliance level.

Cross-Manufacturer Alternatives: Parts from Vishay Dale meeting all electrical and mechanical requirements, offering functional equivalence with different dimensional tolerances and compliance certifications.

Engineering Selection Recommendations

For RoHS3 Compliant Applications: Select 4606X-101-331LF or 4306R-101-331LF. Both parts meet ROHS3 compliance requirements and maintain full electrical equivalence to the original 4606X-101-331. The 4606X-101-331LF is the direct successor within the same product series and is the preferred choice for new designs.

For Non-Compliant or Legacy Systems: The 4306R-101-331 and CSC06A01330RGPA remain functionally equivalent alternatives. The 4306R-101-331 maintains Bourns manufacturing continuity, while CSC06A01330RGPA provides cross-manufacturer sourcing flexibility.

For Active Production: Prioritize 4606X-101-331LF due to active product status and highest inventory availability (1258 pcs). This part eliminates obsolescence risk while maintaining identical electrical performance.

For Packaging Considerations: Bulk packaging (4606X-101-331LF, CSC06A01330RGPA) suits high-volume assembly. Tube packaging (4306R-101-331LF) accommodates lower-volume or manual placement workflows.

Frequently Asked Questions (FAQ)

Q: Can 4606X-101-331LF directly replace 4606X-101-331 on existing PCBs?

A: Yes. Both parts share identical 6-SIP package dimensions, pin configuration, and electrical specifications. The LF suffix indicates lead-free (RoHS3 compliant) construction only. No PCB layout modifications are required.

Q: What is the difference between 4606X and 4306R series parts?

A: Both series are 5-resistor 330 Ohm bussed networks in 6-SIP packages with matching electrical performance. The 4306R series has a specified resistor-ratio-drift of 50ppm/°C, while the 4606X series does not specify this parameter. Dimensional tolerances differ slightly: 4306R measures 14.83mm × 2.16mm versus 4606X at 15.19mm × 2.49mm. Both remain within 6-SIP footprint compatibility.

Q: Is CSC06A01330RGPA suitable for applications requiring RoHS compliance?

A: CSC06A01330RGPA is RoHS non-compliant. For RoHS3 compliance, use 4606X-101-331LF or 4306R-101-331LF.

Q: What is the impact of resistor-ratio-drift on circuit performance?

A: Resistor-ratio-drift (specified for 4306R series at 50ppm/°C) describes the change in resistance matching between individual elements over temperature. For applications requiring tight inter-resistor tolerance stability, the 4306R series provides explicit specification. The 4606X series does not specify this parameter.

Q: Are dimensional variations between substitute parts critical for PCB compatibility?

A: All substitute parts conform to the 6-SIP package standard and share identical pin spacing (0.100" standard DIP pitch). Dimensional variations (length 14.83–15.19mm, width 2.16–2.49mm) fall within normal manufacturing tolerances and do not affect PCB footprint compatibility or insertion reliability.

Q: Which substitute offers the best long-term availability?

A: 4606X-101-331LF is the recommended choice for new designs. It carries active product status from Bourns, the original manufacturer, with the highest current inventory (1258 pcs) and RoHS3 compliance for regulatory alignment.
