CAT10-680J4LF Equivalent & Substitute Parts

Part Overview

The CAT10-680J4LF is a 68 Ohm isolated 4-resistor network array manufactured by Bourns Inc. in an 0804 surface mount package. This component is designed for applications requiring matched resistor networks with ±5% tolerance and operates across the industrial temperature range of -55°C to 125°C. The part is currently in active production status and maintains full RoHS3 compliance. Substitute parts are identified when equivalent electrical specifications and mechanical compatibility are required due to inventory constraints, supply chain considerations, or design flexibility needs.

Substitute Part Grouping Explanation

Substitution eligibility for the CAT10-680J4LF is determined by the following critical parameters:

• Resistance Value: 68 Ohm (exact match required)
• Tolerance: ±5% (exact match required)
• Number of Resistors: 4 (exact match required)
• Circuit Type: Isolated (exact match required)
• Package / Case: 0804, Concave, Long Side Terminals (exact match required)
• Number of Pins: 8 (exact match required)
• Operating Temperature Range: -55°C to 125°C (exact match required)
• Mounting Type: Surface Mount (exact match required)

The EXB-N8V680JX from Panasonic Electronic Components meets all critical substitution criteria. Both parts share identical resistance, tolerance, resistor count, circuit topology, package configuration, pin count, temperature range, and mounting specifications. Differences in power per element (62.5mW vs. 31mW) and temperature coefficient (±250ppm/°C vs. ±200ppm/°C) represent performance variations within acceptable substitution parameters for this component category.

Parameter Comparison

Engineering Selection Recommendations

Both the CAT10-680J4LF and EXB-N8V680JX are active production components with full ROHS3 compliance and unlimited moisture sensitivity ratings. Selection between these parts should be based on availability, lead time, and specific application power dissipation requirements. The CAT10-680J4LF provides higher power per element (62.5mW), while the EXB-N8V680JX offers superior temperature coefficient stability (±200ppm/°C). Both parts are suitable for industrial temperature range applications and maintain identical mechanical compatibility for direct PCB substitution.

Frequently Asked Questions (FAQ)

Q: Can the EXB-N8V680JX directly replace the CAT10-680J4LF on existing PCBs?

A: Yes. Both parts share identical package configuration (0804, Concave, Long Side Terminals), pin count (8), and physical dimensions (2.00mm x 1.00mm x 0.55mm max height). Direct PCB substitution is mechanically and electrically compatible.

Q: What are the key differences between these substitute parts?

A: The primary differences are power per element (CAT10-680J4LF: 62.5mW; EXB-N8V680JX: 31mW) and temperature coefficient (CAT10-680J4LF: ±250ppm/°C; EXB-N8V680JX: ±200ppm/°C). All other electrical and mechanical specifications are identical.

Q: Are both parts compliant with current regulatory standards?

A: Yes. Both the CAT10-680J4LF and EXB-N8V680JX are ROHS3 compliant, REACH unaffected, and classified as EAR99 for export purposes.

Q: What is the operating temperature range for these components?

A: Both parts operate across -55°C to 125°C, suitable for industrial and extended commercial applications.

Q: Does the lower power rating of the EXB-N8V680JX affect substitution suitability?

A: The EXB-N8V680JX's 31mW power per element is lower than the CAT10-680J4LF's 62.5mW. Substitution is appropriate only when application power dissipation requirements do not exceed the EXB-N8V680JX specification.
