Bourns 4610X-101-821 820 Ohm 9-Resistor Network Array Equivalent & Substitute Parts

Part Overview

The Bourns 4610X-101-821 is a 9-resistor bussed network array with 820 Ohm resistance per element, rated at 200mW power dissipation per element, housed in a 10-SIP through-hole package. This part is classified as obsolete. Equivalent and substitute parts are necessary to maintain design continuity and ensure component availability for new production builds and field replacements where the original part is no longer readily available.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 4610X-101-821 is determined by the following critical parameters:

• Resistance value: 820 Ohm (exact match required)
• Tolerance: ±2% (exact match required)
• Number of resistors: 9 (exact match required)
• Circuit type: Bussed (exact match required)
• Power per element: 200mW (exact match required)
• Temperature coefficient: ±100ppm/°C (exact match required)
• Operating temperature range: -55°C to 125°C (exact match required)
• Number of pins: 10 (exact match required)
• Package type: 10-SIP (exact match required)
• Mounting type: Through Hole (exact match required)

All identified substitute parts meet these core electrical and mechanical specifications. Variations in physical dimensions, resistor-ratio-drift, RoHS compliance status, and packaging format (bulk vs. tube) do not affect functional interchangeability within the specified parameter constraints.

Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation: 4610X-101-821LF (Bourns Inc.)

The 4610X-101-821LF is the direct successor to the obsolete 4610X-101-821. Both parts share identical electrical specifications and the same base product number (4610X). The LF variant is currently in active production status and carries ROHS3 compliance certification, making it the preferred choice for new designs and production builds requiring regulatory compliance.

Secondary Recommendation: 4310R-101-821LF (Bourns Inc.)

The 4310R-101-821LF is an active Bourns product from the 4300R series with ROHS3 compliance. It meets all core electrical parameters and is available in tube packaging. This part is suitable for applications where the 4610X-101-821LF is unavailable.

Alternative Options: Vishay Dale CSC and MSP Series

The CSC10A01820RGPA and MSP10A01820RGEJ from Vishay Dale are functionally equivalent alternatives from a different manufacturer. The MSP10A01820RGEJ carries ROHS3 compliance. Both parts meet all specified electrical and mechanical requirements and are currently in active production.

Compliance Considerations

For applications requiring RoHS compliance, select parts with ROHS3 designation: 4610X-101-821LF, 4310R-101-821LF, or MSP10A01820RGEJ. For applications without RoHS requirements, all listed parts are functionally interchangeable.

Frequently Asked Questions (FAQ)

Q: Can the 4610X-101-821LF be used as a direct replacement for the obsolete 4610X-101-821?

A: Yes. Both parts are electrically and mechanically identical. The LF variant is the active production equivalent with improved compliance status.

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

A: Both series meet the specified electrical parameters for this application. The 4310R series has a documented resistor-ratio-drift specification of 50ppm/°C, while the 4610X series does not specify this parameter. Physical dimensions vary slightly between series.

Q: Are the Vishay Dale CSC and MSP parts compatible with Bourns parts in the same circuit?

A: Yes. All listed parts meet identical electrical specifications (820 Ohm ±2%, 200mW per element, ±100ppm/°C temperature coefficient, 10-SIP package). They are functionally interchangeable.

Q: Does packaging format (bulk vs. tube) affect electrical performance?

A: No. Packaging format affects only handling, storage, and ordering logistics. Electrical and mechanical specifications remain identical regardless of packaging format.

Q: Which part should I select for a new design?

A: For new designs, select 4610X-101-821LF (Bourns) or MSP10A01820RGEJ (Vishay Dale) if RoHS3 compliance is required. Both are in active production with full availability.

Q: Are there any pin configuration differences between these parts?

A: No. All parts are 10-pin SIP packages with identical pin configurations and bussed circuit topology.
