Bourns 4306M-101-331 Equivalent & Substitute Parts

Part Overview

The Bourns 4306M-101-331 is a 5-resistor network array with 330 Ohm resistance values in a 6-SIP through-hole package. This component is classified as Active product status and is currently in stock. Substitute parts are identified when equivalent electrical specifications and mechanical compatibility allow direct replacement in circuit applications, particularly when addressing packaging preferences, compliance requirements, or inventory availability.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 4306M-101-331 is determined by the following critical parameters:

• Resistance value: 330 Ohm (exact match required)
• Tolerance: ±2% (exact match required)
• Circuit type: Bussed (exact match required)
• Number of resistors: 5 (exact match required)
• Number of pins: 6 (exact match required)
• Package / Case: 6-SIP (exact match required)
• Temperature coefficient: ±100ppm/°C (exact match required)
• Operating temperature range: -55°C ~ 125°C (exact match required)
• Mounting type: Through Hole (exact match required)

The 4306R-101-331LF meets all critical electrical and mechanical parameters. Differences in power per element rating (250mW vs. 200mW) and physical height do not prevent substitution when the application power dissipation requirements do not exceed the substitute part's rating. Packaging format and RoHS compliance status differ but do not affect electrical interchangeability.

Parameter Comparison

Engineering Selection Recommendations

Both the 4306M-101-331 and 4306R-101-331LF are Active status components from Bourns Inc. with identical electrical specifications for resistance, tolerance, temperature coefficient, and operating range.

Selection between these parts should be based on:

• Power dissipation requirements: The 4306M-101-331 supports 250mW per element, while the 4306R-101-331LF supports 200mW per element. Applications requiring power dissipation above 200mW per element necessitate the 4306M variant.
• RoHS compliance: The 4306R-101-331LF is ROHS3 compliant, while the 4306M-101-331 is RoHS non-compliant. Designs subject to RoHS requirements must use the 4306R variant.
• Physical height constraints: The 4306R-101-331LF has a maximum seated height of 0.195" compared to 0.250" for the 4306M-101-331. Space-constrained PCB layouts may benefit from the lower profile substitute.
• Packaging format: The 4306R-101-331LF is supplied in Tube packaging, while the 4306M-101-331 packaging format is not specified.

Frequently Asked Questions (FAQ)

Q: Can the 4306R-101-331LF replace the 4306M-101-331 in all applications?

A: Substitution is valid when the application power dissipation per resistor element does not exceed 200mW. If your circuit requires power dissipation above 200mW per element, the 4306M-101-331 must be used.

Q: Are there pin-to-pin compatibility differences between these parts?

A: No. Both parts are 6-SIP packages with identical pin counts and bussed circuit topology. Pin-to-pin compatibility is confirmed.

Q: Does the height difference affect PCB layout compatibility?

A: The 4306R-101-331LF is 0.055" shorter in seated height. If your PCB layout has height clearance constraints, the substitute part may provide additional margin. Verify clearance requirements for your specific application.

Q: What is the impact of RoHS compliance differences?

A: The 4306R-101-331LF is ROHS3 compliant, while the 4306M-101-331 is not. If your design or end-market requires RoHS compliance, the 4306R-101-331LF must be selected.

Q: Are the electrical characteristics identical?

A: Yes. Both parts share identical resistance values (330 Ohm), tolerance (±2%), temperature coefficient (±100ppm/°C), resistor-ratio-drift (50ppm/°C), and operating temperature range (-55°C ~ 125°C).
