Bourns 4610X-102-681 Equivalent & Substitute Parts

Part Overview

The Bourns 4610X-102-681 is a 5-resistor isolated network array with 680 Ohm resistance, ±2% tolerance, and 300mW power per element in a 10-SIP through-hole package. This part is classified as obsolete, making equivalent substitutes necessary for ongoing production and maintenance applications. Active alternatives from Bourns maintain identical electrical specifications while offering improved compliance status and availability.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the 4610X-102-681 is determined by matching the following critical parameters: resistance value (680 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 configuration (10-SIP through hole).

Three substitute parts meet these electrical and mechanical requirements:

1. 4610X-102-681LF — Direct successor with identical specifications, active product status, and RoHS3 compliance
2. 4310R-102-681 — Alternative series with matching electrical performance, active status, different physical dimensions
3. 4310R-102-681LF — RoHS3 compliant variant of the 4310R series with identical electrical specifications

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: 4610X-102-681LF

The 4610X-102-681LF is the direct active replacement for the obsolete 4610X-102-681. It maintains identical electrical specifications, physical dimensions, and 10-SIP package configuration. The LF suffix indicates RoHS3 compliance, meeting current regulatory requirements. This part is the preferred choice for direct board-level substitution without design modification.

Alternative Substitutes: 4310R-102-681 and 4310R-102-681LF

The 4310R series parts provide equivalent electrical performance with identical resistance, tolerance, power rating, and temperature characteristics. Physical dimensions differ slightly (length 24.99mm vs. 25.35mm, width 2.16mm vs. 2.49mm, height 4.95mm vs. 5.08mm). These parts are suitable for applications where minor dimensional variations are acceptable. The 4310R-102-681LF variant offers RoHS3 compliance for regulatory-sensitive applications.

Compliance Considerations

For new designs or applications requiring RoHS3 compliance, select either 4610X-102-681LF or 4310R-102-681LF. For legacy systems where RoHS compliance is not mandated, 4310R-102-681 remains available. All active substitutes support the full operating temperature range of -55°C to 125°C.

Frequently Asked Questions (FAQ)

Q: Can 4610X-102-681LF be used as a direct replacement for 4610X-102-681?

A: Yes. The 4610X-102-681LF is electrically and mechanically identical to the obsolete 4610X-102-681, with identical package dimensions and pin configuration. No board redesign is required.

Q: What is the difference between 4610X and 4310R series parts?

A: Both series provide identical electrical specifications (680 Ohm, ±2%, 300mW, ±100ppm/°C). The 4310R series has slightly smaller physical dimensions. Both are compatible with 10-SIP through-hole footprints, though PCB layout verification is recommended for the 4310R variants due to dimensional differences.

Q: Are the 4310R parts suitable for high-reliability applications?

A: The 4310R-102-681 and 4310R-102-681LF meet the same electrical performance specifications as the 4610X series. Selection depends on compliance requirements (RoHS3 for LF variants) and dimensional constraints of the application.

Q: What packaging options are available?

A: The 4610X-102-681LF is supplied in bulk packaging. The 4310R-102-681 and 4310R-102-681LF are supplied in tube packaging. Packaging selection may affect procurement lead times and handling procedures.

Q: Can these parts be used interchangeably in existing designs?

A: The 4610X-102-681LF is a direct interchange with identical dimensions. The 4310R variants have minor dimensional differences and require verification that PCB footprint tolerances accommodate the smaller package size before implementation.
