Bourns 4606X-101-821 Equivalent & Substitute Parts

Part Overview

The Bourns 4606X-101-821 is a 5-resistor network array with 820 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 ongoing production and maintenance applications. Substitute parts must maintain identical electrical specifications and mechanical compatibility within the 6-SIP form factor.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict equivalence across the following parameters: resistance value (820 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). Parts are grouped into direct equivalents (identical specifications and compliance status) and compatible alternatives (equivalent electrical performance with minor dimensional or compliance variations).

Parameter Comparison

Engineering Selection Recommendations

4606X-101-821LF is the primary direct substitute. It is manufactured by Bourns Inc. in the same 4600X series, maintains all electrical and mechanical specifications of the original part, and carries active product status with ROHS3 compliance. This part provides the most seamless transition from the obsolete 4606X-101-821.

4306R-101-821LF is a compatible alternative from Bourns Inc. in the 4300R series. It meets all core electrical requirements and achieves ROHS3 compliance with active product status. The 4300R series exhibits a resistor-ratio-drift specification of 50ppm/°C and minor dimensional variations (0.584" L x 0.085" W versus 0.598" L x 0.098" W for the original). REACH status is affected for this part.

4306R-101-821 is functionally equivalent to 4306R-101-821LF but lacks ROHS3 compliance and carries non-compliant RoHS status. Selection should be limited to applications where RoHS compliance is not required.

CSC06A01820RGPA is a Vishay Dale equivalent from the CSC series. It satisfies all electrical specifications and maintains through-hole 6-SIP compatibility. Dimensional variation is minimal (0.590" L x 0.098" W). This part is RoHS non-compliant and carries REACH unaffected status. MSL rating is 1 (unlimited).

For new designs and RoHS-regulated applications, 4606X-101-821LF is the recommended selection. For legacy system maintenance where RoHS compliance is not mandated, all listed substitutes are electrically and mechanically compatible.

Frequently Asked Questions (FAQ)

Q: Can 4606X-101-821LF be used as a direct replacement for 4606X-101-821?

A: Yes. Both parts are manufactured by Bourns Inc. in the 4600X series with identical electrical specifications (820 Ohm, ±2%, 200mW, ±100ppm/°C) and mechanical form factor (6-SIP through-hole). The primary difference is product status (active versus obsolete) and RoHS compliance (ROHS3 versus non-compliant).

Q: What are the key differences between the 4600X and 4300R series?

A: Both series meet the core electrical requirements of 820 Ohm, ±2% tolerance, 200mW power per element, and ±100ppm/°C temperature coefficient. The 4300R series specifies resistor-ratio-drift at 50ppm/°C and exhibits minor dimensional variations in length and width. Mechanical compatibility with 6-SIP through-hole PCB layouts is maintained.

Q: Is CSC06A01820RGPA suitable for RoHS-compliant applications?

A: No. CSC06A01820RGPA carries RoHS non-compliant status. For RoHS-regulated applications, select 4606X-101-821LF or 4306R-101-821LF.

Q: Are there dimensional constraints when substituting between these parts?

A: All parts conform to the 6-SIP through-hole package standard. Minor dimensional variations exist: 4606X series measures 0.598" L x 0.098" W; 4300R series measures 0.584" L x 0.085" W; CSC series measures 0.590" L x 0.098" W. These variations remain within standard 6-SIP tolerances and do not affect PCB footprint compatibility.

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

A: 4606X-101-821LF carries active product status from Bourns Inc. and is the recommended long-term selection. 4306R-101-821LF and CSC06A01820RGPA also maintain active status.
