Key Parameters

Substitute Part Grouping Explanation

Substitution for the 4610X-102-821 is determined by the following critical parameters: resistance value (820 Ohm), tolerance (±2%), number of resistors (5), circuit type (isolated), power per element (300mW), temperature coefficient (±100ppm/°C), operating temperature range (-55°C to 125°C), pin count (10), and package type (10-SIP through-hole).

Substitute parts are grouped into two categories:

Direct Equivalent: Parts maintaining identical electrical specifications and package dimensions with updated manufacturing standards and compliance certifications.

Similar Alternative: Parts meeting all core electrical specifications with minor dimensional variations and different resistor-ratio-drift characteristics, suitable for applications where physical space constraints are less critical.

Parameter Comparison

Engineering Selection Recommendations

4610X-102-821LF (Direct Equivalent): This part is the primary substitute for the obsolete 4610X-102-821. It maintains identical electrical specifications, package dimensions, and pin configuration. The LF suffix indicates lead-free manufacturing and ROHS3 compliance, meeting modern regulatory requirements. This part is in active production status with 769 units in stock.

4310R-102-821 and 4310R-102-821LF (Similar Alternatives): These parts from the 4300R series provide equivalent electrical performance with documented resistor-ratio-drift of 50ppm/°C. Physical dimensions are slightly reduced (0.984" L x 0.085" W versus 0.998" L x 0.098" W), and seated height is marginally lower (0.195" versus 0.200"). The 4310R-102-821LF variant offers ROHS3 compliance for applications requiring modern regulatory adherence. Both 4300R variants are in active production.

Selection between direct equivalent and similar alternatives depends on physical space constraints and regulatory compliance requirements. For applications with strict dimensional specifications, the 4610X-102-821LF is the appropriate choice. For applications where minor dimensional reduction is acceptable, the 4310R series provides additional inventory availability.

Frequently Asked Questions (FAQ)

Q: Can the 4610X-102-821LF directly replace the obsolete 4610X-102-821?

A: Yes. The 4610X-102-821LF maintains identical electrical specifications (820 Ohm, ±2% tolerance, 300mW per element, ±100ppm/°C temperature coefficient) and package dimensions (0.998" L x 0.098" W, 10-SIP through-hole). The primary difference is the LF designation indicating lead-free manufacturing and ROHS3 compliance.

Q: What are the dimensional differences between the 4610X and 4310R series?

A: The 4610X-102-821 measures 0.998" L x 0.098" W with 0.200" seated height. The 4310R-102-821 measures 0.984" L x 0.085" W with 0.195" seated height. These differences are approximately 1.4% in length, 13.3% in width, and 2.5% in height. Applications with tight PCB layout constraints should account for these variations.

Q: Are all substitute parts compatible with the same PCB footprint?

A: The 4610X-102-821LF uses identical footprint dimensions to the original 4610X-102-821. The 4310R series parts have slightly different dimensions and may require PCB layout verification before implementation.

Q: What is the significance of the LF suffix?

A: The LF suffix indicates lead-free (RoHS3 compliant) manufacturing. Parts without the LF suffix are RoHS non-compliant. For applications subject to RoHS regulations or requiring modern manufacturing standards, LF variants are required.

Q: How do the 4300R and 4600X series differ?

A: Both series provide 5-resistor isolated networks with identical electrical specifications for this application. The 4300R series specifies resistor-ratio-drift of 50ppm/°C, while the 4600X series does not specify this parameter. The 4300R series has slightly smaller physical dimensions.

Q: What packaging options are available?

A: The 4610X-102-821LF is supplied in bulk packaging. The 4310R-102-821 and 4310R-102-821LF are supplied in tube packaging. Packaging selection depends on production volume and handling requirements.
