Substitute Part Grouping Explanation

The 4606X-101-220LF qualifies as a direct substitute for the 4306R-101-220LF based on the following critical parameters:

• Identical resistance value: 22 Ohm
• Identical tolerance: ±1 Ohm
• Identical number of resistors: 5
• Identical power per element: 200 mW
• Identical temperature coefficient: ±250 ppm/°C
• Identical operating temperature range: -55°C to 125°C
• Identical circuit type: Bussed
• Identical package type: 6-SIP through hole
• Identical pin count: 6

The primary difference between these parts is packaging format (Tube versus Bulk) and minor dimensional variations within acceptable mechanical tolerances. Both parts maintain ROHS3 compliance and are manufactured by Bourns Inc.

Parameter Comparison

Engineering Selection Recommendations

Both the 4306R-101-220LF and 4606X-101-220LF are active production parts from Bourns Inc. with identical electrical specifications and ROHS3 compliance. Selection between these parts should be based on:

• Packaging requirements: The 4306R is supplied in Tube packaging, while the 4606X is supplied in Bulk packaging. Choose based on assembly process and quantity requirements.
• Inventory availability: The 4606X-101-220LF currently has higher stock availability (2835 units) compared to the 4306R-101-220LF (797 units).
• Mechanical fit: Minor dimensional differences exist between the two parts. Verify PCB footprint compatibility if space constraints are critical.

Both parts satisfy identical electrical and thermal requirements for applications operating within the -55°C to 125°C temperature range.

Frequently Asked Questions (FAQ)

Q: Can the 4606X-101-220LF be used as a direct replacement for the 4306R-101-220LF?

A: Yes. Both parts have identical electrical specifications, including resistance value, tolerance, power rating, temperature coefficient, and operating temperature range. The primary difference is packaging format (Tube versus Bulk).

Q: What are the key parameters that determine substitutability?

A: Substitutability is determined by: resistance value (22 Ohm), tolerance (±1 Ohm), number of resistors (5), power per element (200 mW), temperature coefficient (±250 ppm/°C), operating temperature range (-55°C to 125°C), circuit type (Bussed), and package type (6-SIP through hole).

Q: Are there dimensional differences between these parts?

A: Minor dimensional variations exist. The 4306R-101-220LF measures 0.584" L x 0.085" W x 0.195" H (max), while the 4606X-101-220LF measures 0.598" L x 0.098" W x 0.200" H (max). Verify PCB layout compatibility before substitution.

Q: Do both parts meet the same compliance standards?

A: Both parts are ROHS3 compliant and carry EAR99 ECCN classification. The 4306R-101-220LF is REACH Affected, while the 4606X-101-220LF is REACH Unaffected. Verify compliance requirements for your specific application.

Q: Which part should I select based on availability?

A: The 4606X-101-220LF has significantly higher stock availability (2835 units) compared to the 4306R-101-220LF (797 units). If lead time is a concern, the 4606X is the preferred choice.
