Bourns 4610X-101-331 Equivalent & Substitute Parts

Part Overview

The Bourns 4610X-101-331 is a 330 Ohm bussed resistor network array with nine resistors in a 10-SIP through-hole package. This component is classified as obsolete, making equivalent and substitute parts necessary for ongoing production and maintenance applications. The part delivers 200mW power per element with ±2% tolerance and ±100ppm/°C temperature coefficient across an operating range of -55°C to 125°C.

Substitute Part Grouping Explanation

Substitution for the 4610X-101-331 is determined by strict equivalence in the following parameters: resistance value (330 Ohm), tolerance (±2%), number of resistors (9), circuit type (bussed), power per element (200mW), temperature coefficient (±100ppm/°C), pin count (10), package type (10-SIP), and through-hole mounting. Substitute parts must maintain these electrical and mechanical specifications to ensure functional compatibility in the original application.

The substitute parts are grouped into two categories:

Direct Bourns Substitutes: Parts from the same manufacturer that maintain identical electrical specifications and package dimensions, differing only in product status (active vs. obsolete) or RoHS compliance level.

Cross-Manufacturer Substitutes: Parts from Vishay Dale that meet all core electrical parameters and package requirements, with minor dimensional variations within acceptable tolerances for through-hole mounting.

Engineering Selection Recommendations

Primary Recommendation: 4610X-101-331LF (Bourns Inc.)

This part is the direct active equivalent of the obsolete 4610X-101-331, maintaining identical electrical specifications and package dimensions while offering ROHS3 compliance. It is available in bulk packaging with 3030 units in stock.

Secondary Recommendations: 4310R-101-331LF (Bourns Inc.)

This active Bourns part from the 4300R series meets all core electrical and mechanical requirements with ROHS3 compliance. It is available in tube packaging with 3910 units in stock. Minor dimensional variations (0.984" L x 0.085" W vs. 0.998" L x 0.098" W) are within acceptable tolerances for through-hole mounting applications.

Cross-Manufacturer Alternative: MSP10A01330RGEJ (Vishay Dale)

This part meets all electrical specifications and package requirements with ROHS3 compliance. It is available in tube packaging with 918 units in stock. Dimensional variations are within acceptable tolerances for through-hole mounting.

Legacy Compliance Option: 4310R-101-331 (Bourns Inc.)

This part maintains all electrical specifications but is RoHS non-compliant. It is available in tube packaging with 3163 units in stock and is suitable only for applications without RoHS requirements.

Frequently Asked Questions (FAQ)

Q: Can I use 4610X-101-331LF as a direct replacement for the obsolete 4610X-101-331?

A: Yes. The 4610X-101-331LF is the active equivalent with identical electrical specifications (330 Ohm, ±2%, 200mW per element, ±100ppm/°C), package type (10-SIP), and dimensions. The primary difference is product status (active vs. obsolete) and RoHS compliance (ROHS3 vs. non-compliant).

Q: What are the key differences between Bourns 4610X and 4310R series parts?

A: Both series meet the core electrical requirements (330 Ohm, ±2%, 200mW, ±100ppm/°C, 10-SIP package). The 4310R series has a documented resistor-ratio-drift specification of 50ppm/°C and slightly smaller physical dimensions (0.984" L x 0.085" W vs. 0.998" L x 0.098" W). These differences do not affect functional compatibility in standard through-hole mounting applications.

Q: Are Vishay Dale parts (CSC10A01330RGPA, MSP10A01330RGEJ) compatible with the original Bourns 4610X-101-331?

A: Yes. Both Vishay Dale parts meet all core electrical specifications and the 10-SIP package requirement. Dimensional variations are minor and within acceptable tolerances for through-hole mounting. The MSP10A01330RGEJ offers ROHS3 compliance, while the CSC10A01330RGPA does not.

Q: Which substitute part should I select for new designs requiring RoHS compliance?

A: Select either 4610X-101-331LF, 4310R-101-331LF, or MSP10A01330RGEJ. All three parts are ROHS3 compliant and meet the electrical and mechanical requirements of the original part.

Q: What is the difference between bulk and tube packaging options?

A: Bulk packaging (4610X-101-331LF, CSC10A01330RGPA) is suitable for high-volume production and automated assembly. Tube packaging (4310R-101-331, 4310R-101-331LF, MSP10A01330RGEJ) is appropriate for lower-volume applications and manual handling. Electrical and mechanical specifications are identical regardless of packaging type.

Q: Can I mix substitute parts from different manufacturers in the same assembly?

A: Yes. All listed substitute parts meet identical electrical specifications and package requirements. However, for consistency in procurement and quality control, using parts from a single manufacturer or series is recommended for production batches.
