Key Parameters

Substitute Part Grouping Explanation

Substitution compatibility for the 4309R-101-220LF is determined by the following critical parameters:

Core Electrical Parameters:

• Resistance value: 22 Ohm (exact match required)
• Circuit topology: Bussed configuration (8 resistor array)
• Number of pins: 9-SIP package format
• Operating temperature range: -55°C to 125°C
• Temperature coefficient: ±250ppm/°C

Application-Dependent Parameters:

• Power per element rating
• Tolerance specification
• Packaging format (tube versus bulk)

The Bourns 4609X-101-220LF qualifies as a substitute part based on matching resistance value, circuit type, pin configuration, operating temperature range, and temperature coefficient. Differences in power rating and tolerance must be evaluated against specific circuit requirements.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection Criteria:

The 4309R-101-220LF remains the preferred component when power dissipation requirements reach 750mW per element and ±2% tolerance specifications are mandated by circuit design parameters.

The 4609X-101-220LF serves as a functional substitute when circuit power dissipation does not exceed 200mW per element and tolerance requirements can accommodate ±1 Ohm specification. Both components maintain identical operating temperature ranges, temperature coefficients, and ROHS3 compliance status.

Compliance Considerations:

Both parts are ROHS3 compliant and suitable for applications requiring environmental regulatory adherence. The 4309R-101-220LF carries REACH Affected status, while the 4609X-101-220LF is REACH Unaffected. Selection between these parts may be influenced by supply chain compliance documentation requirements.

Packaging Considerations:

The 4309R-101-220LF is supplied in tube packaging, while the 4609X-101-220LF is supplied in bulk packaging. Packaging format selection depends on procurement volume requirements and inventory management protocols.

Frequently Asked Questions (FAQ)

Q: Can the 4609X-101-220LF replace the 4309R-101-220LF in all applications?

A: The 4609X-101-220LF is electrically compatible only in applications where power dissipation per element does not exceed 200mW. The main part 4309R-101-220LF is rated for 750mW per element. Circuits requiring higher power dissipation must use the 4309R-101-220LF.

Q: What is the difference between ±2% and ±1 Ohm tolerance specifications?

A: The 4309R-101-220LF specifies ±2% tolerance, which equals ±0.44 Ohm at 22 Ohm nominal value. The 4609X-101-220LF specifies ±1 Ohm absolute tolerance. For 22 Ohm resistors, the ±1 Ohm specification represents approximately ±4.5% tolerance. Applications requiring tighter tolerance control must use the 4309R-101-220LF.

Q: Are both parts suitable for -55°C to 125°C operating environments?

A: Both the 4309R-101-220LF and 4609X-101-220LF operate across the identical temperature range of -55°C to 125°C with ±250ppm/°C temperature coefficient. Temperature performance is equivalent between the two parts.

Q: What packaging format should be selected for high-volume production?

A: The 4609X-101-220LF is available in bulk packaging, which is standard for high-volume manufacturing operations. The 4309R-101-220LF is supplied in tube packaging, suitable for lower-volume or component-level inventory management.

Q: Do both parts require identical PCB footprints?

A: Both parts use the 9-SIP package configuration with identical pin counts and through-hole mounting type. PCB footprints are compatible. Physical dimensions show minor variations: the 4309R-101-220LF measures 0.884" L x 0.085" W with 0.195" maximum seated height, while the 4609X-101-220LF measures 0.898" L x 0.098" W with 0.200" maximum seated height. These dimensional differences are within standard PCB layout tolerances for through-hole components.

Q: What is the significance of REACH Affected versus REACH Unaffected status?

A: REACH Affected status indicates the component may contain substances subject to REACH regulatory requirements. REACH Unaffected status indicates no REACH-regulated substances are present. Selection between these parts depends on supply chain compliance documentation and regulatory requirements specific to the end application and geographic market.
