Substitute Part Grouping Explanation

Substitution eligibility for the 4606X-101-683 is determined by strict equivalence across the following parameters: resistance value (68kΩ), number of resistors (5), tolerance (±2%), power per element (200mW), circuit topology (bussed), package type (6-SIP), mounting method (through hole), temperature coefficient (±100ppm/°C), and operating temperature range (-55°C to 125°C).

The substitute parts are grouped into two categories:

Direct Equivalent (Same Series): 4606X-101-683LF maintains identical electrical specifications and physical dimensions while offering improved compliance status.

Functional Equivalent (Alternative Series): 4306R-101-683 and 4306R-101-683LF provide the same electrical performance and package footprint but belong to the 4300R series with minor dimensional variations and different resistor-ratio-drift specifications (50ppm/°C vs. not specified for the main part).

Engineering Selection Recommendations

For RoHS3 Compliance Requirements: Select 4606X-101-683LF or 4306R-101-683LF. Both parts meet ROHS3 compliance standards, whereas the original 4606X-101-683 does not.

For Direct Series Continuity: The 4606X-101-683LF is the preferred substitute, maintaining identical dimensions and series designation while offering active product status and improved compliance.

For Alternative Series Selection: The 4306R series (4306R-101-683 or 4306R-101-683LF) provides functional equivalence with minor dimensional differences. The 4306R-101-683LF is recommended when both active status and RoHS3 compliance are required.

For REACH Compliance Considerations: The 4306R series parts are REACH Affected, whereas the 4606X series parts are REACH Unaffected. Select accordingly based on regulatory requirements.

Frequently Asked Questions (FAQ)

Q: Can the 4606X-101-683LF be used as a direct replacement for the 4606X-101-683?

A: Yes. The 4606X-101-683LF is electrically and mechanically identical to the main part, with identical dimensions, resistance value, tolerance, power rating, and temperature coefficient. The primary differences are active product status and RoHS3 compliance.

Q: What are the dimensional differences between the 4606X and 4306R series?

A: The 4606X series measures 0.598" L x 0.098" W with 0.200" seated height. The 4306R series measures 0.584" L x 0.085" W with 0.195" seated height. Both fit 6-SIP through-hole footprints but with minor variations in physical envelope.

Q: Are the 4306R parts suitable substitutes despite dimensional differences?

A: Yes, for applications where the 6-SIP through-hole footprint is the primary constraint. The 4306R series maintains all critical electrical parameters: 68kΩ resistance, ±2% tolerance, 200mW power per element, ±100ppm/°C temperature coefficient, and -55°C to 125°C operating range. Dimensional differences are minor and typically accommodated by standard PCB layouts.

Q: What is the significance of the resistor-ratio-drift specification on the 4306R parts?

A: The 4306R series specifies 50ppm/°C resistor-ratio-drift, whereas the 4606X series does not provide this specification. This parameter describes the temperature-dependent matching between individual resistors within the array. Applications requiring tight resistor matching over temperature should account for this difference.

Q: Which substitute part should be selected for new designs?

A: For new designs, 4606X-101-683LF is recommended as the primary choice due to active product status, RoHS3 compliance, and series continuity. The 4306R-101-683LF is an acceptable alternative when 4606X availability is constrained.

Q: Are packaging differences between bulk and tube significant for component selection?

A: Packaging differences (bulk vs. tube) affect handling, storage, and procurement logistics but do not impact electrical or mechanical compatibility. Selection should be based on manufacturing process requirements and inventory management practices.
