Bourns 4610X-102-221 Equivalent & Substitute Parts

Part Overview

The Bourns 4610X-102-221 is a 5-resistor isolated network array with 220 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 and Vishay Dale maintain identical electrical specifications and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 4610X-102-221 is determined by the following criteria:

Electrical Parameters (Must Match):

• Resistance value: 220 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
• Number of pins: 10

Mechanical Parameters (Must Match):

• Package type: 10-SIP
• Mounting type: Through Hole

All substitute parts listed meet these criteria. Variations in physical dimensions, RoHS compliance status, and resistor-ratio-drift do not prevent functional substitution within the specified electrical and mechanical constraints.

Engineering Selection Recommendations

Primary Recommendation: 4610X-102-221LF

The 4610X-102-221LF is the direct successor to the 4610X-102-221 within the Bourns 4600X series. It maintains identical electrical and mechanical specifications while offering ROHS3 compliance and active product status. This part is the preferred choice for new designs and production continuity.

Secondary Recommendation: 4310R-102-221LF

The 4310R-102-221LF from the Bourns 4300R series provides full electrical and mechanical compatibility. It offers ROHS3 compliance and active status. The 4310R series exhibits a resistor-ratio-drift specification of 50ppm/°C compared to the unspecified drift in the 4610X series. Physical dimensions differ slightly but remain within 10-SIP package constraints.

Alternative Recommendation: CSC10A03220RGPA

The Vishay Dale CSC10A03220RGPA provides cross-manufacturer compatibility with identical electrical specifications. It is actively produced and available in bulk packaging. This option is suitable when Bourns parts are unavailable or when multi-source qualification is required.

Compliance Consideration:

For applications requiring RoHS3 compliance, select 4610X-102-221LF or 4310R-102-221LF. For legacy systems or applications without compliance requirements, all listed parts are functionally equivalent.

Frequently Asked Questions (FAQ)

Q: Can the 4610X-102-221LF directly replace the obsolete 4610X-102-221?

A: Yes. The 4610X-102-221LF is electrically and mechanically identical to the 4610X-102-221. Both share the same resistance value, tolerance, power rating, temperature coefficient, and 10-SIP package configuration. The primary difference is product status (active vs. obsolete) and RoHS compliance.

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

A: Both series meet the specified electrical parameters for this application. The 4310R series specifies a resistor-ratio-drift of 50ppm/°C, while the 4610X series does not specify this parameter. Physical dimensions vary slightly between series, but both conform to 10-SIP through-hole packaging.

Q: Is the Vishay Dale CSC10A03220RGPA compatible with Bourns parts?

A: Yes. The CSC10A03220RGPA meets all electrical and mechanical requirements. It is suitable for applications requiring cross-manufacturer sourcing or when Bourns inventory is constrained.

Q: Are there any packaging differences between these parts?

A: The 4610X-102-221LF is supplied in bulk packaging, while 4310R series parts are supplied in tubes. CSC10A03220RGPA is supplied in bulk. Packaging does not affect electrical or mechanical compatibility; it affects only handling and storage logistics.

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

A: The 4610X-102-221LF is recommended for new designs as the active direct successor to the obsolete 4610X-102-221. It provides continuity within the same series and offers ROHS3 compliance.
