CAT10-105J4LF Equivalent & Substitute Parts

Part Overview

The CAT10-105J4LF is a 1M Ohm isolated 4-resistor network array manufactured by Bourns Inc. in 0804 surface mount package with concave, long side terminals. This component is designed for applications requiring matched resistor networks with ±5% tolerance and operates across the -55°C to 125°C temperature range. The part is currently in active production status with ROHS3 compliance and unlimited moisture sensitivity rating. Substitute parts are identified when equivalent electrical specifications and mechanical compatibility are maintained within the allowed parameter tolerances for this resistor array category.

Substitute Part Grouping Explanation

Substitution eligibility for the CAT10-105J4LF is determined by strict equivalence in the following parameters:

• Resistance value: 1M Ohm
• Tolerance: ±5%
• Number of resistors: 4
• Circuit configuration: Isolated
• Package designation: 0804 with concave, long side terminals
• Pin count: 8
• Operating temperature range: -55°C ~ 125°C minimum
• Surface mount compatibility
• RoHS3 compliance status

The EXB-N8V105JX from Panasonic Electronic Components meets all substitution criteria. Variations in power per element (62.5mW vs. 31mW) and temperature coefficient (±250ppm/°C vs. ±200ppm/°C) remain within acceptable ranges for isolated resistor network applications where these parameters are not design-critical constraints.

Parameter Comparison

Engineering Selection Recommendations

Both the CAT10-105J4LF and EXB-N8V105JX are active production components with ROHS3 compliance and identical moisture sensitivity ratings. Selection between these parts should be based on:

• Availability and lead time requirements
• Power dissipation constraints in the application circuit
• Temperature coefficient stability requirements
• Preferred supplier relationships and inventory management

The EXB-N8V105JX offers lower power per element (31mW vs. 62.5mW), which may provide thermal advantages in power-sensitive applications. The CAT10-105J4LF provides higher power rating capability and slightly broader temperature coefficient tolerance.

Frequently Asked Questions (FAQ)

Q: Can EXB-N8V105JX directly replace CAT10-105J4LF in existing designs?

A: Yes, provided the application does not require the higher power per element specification of the CAT10-105J4LF. Both parts share identical resistance, tolerance, pin configuration, and package dimensions.

Q: What is the significance of the power per element difference?

A: Power per element rating indicates the maximum power dissipation capability per individual resistor within the array. The CAT10-105J4LF supports 62.5mW per element while the EXB-N8V105JX supports 31mW per element. Applications with high current or voltage stress should verify compatibility with the lower rating.

Q: Are there differences in temperature stability between these parts?

A: The CAT10-105J4LF has a temperature coefficient of ±250ppm/°C while the EXB-N8V105JX has ±200ppm/°C. The Panasonic part exhibits tighter temperature stability. For precision analog circuits, this difference may be relevant.

Q: Do both parts use the same PCB footprint?

A: Yes. Both components use the 0804 package with concave, long side terminals and identical physical dimensions (0.079" L x 0.039" W, 2.00mm x 1.00mm), with maximum seated height of 0.022" (0.55mm).

Q: Are both parts compliant with current environmental regulations?

A: Yes. Both CAT10-105J4LF and EXB-N8V105JX are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.
