Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CAT10-820J4LF is determined by strict alignment of the following critical parameters:

• Resistance value: 82 Ohm (exact match required)
• Tolerance: ±5% (exact match required)
• Circuit configuration: Isolated 4-resistor network (exact match required)
• Package format: 0804, Concave, Long Side Terminals (exact match required)
• Number of pins: 8 (exact match required)
• Operating temperature range: -55°C ~ 125°C (exact match required)
• Mounting type: Surface Mount (exact match required)

The substitute part 741C083820JP meets all substitution criteria. Variations in power per element (62.5mW vs. 63mW) and temperature coefficient (±250ppm/°C vs. ±200ppm/°C) remain within acceptable engineering tolerances for isolated resistor network applications and do not preclude functional equivalence.

Parameter Comparison

Engineering Selection Recommendations

Both the CAT10-820J4LF and 741C083820JP maintain active product status with full regulatory compliance. The CAT10-820J4LF is manufactured by Bourns Inc. and the 741C083820JP by CTS Resistor Products. Both components carry ROHS3 certification and REACH unaffected status, meeting current environmental and regulatory requirements.

The 741C083820JP offers a marginal improvement in temperature coefficient performance (±200ppm/°C versus ±250ppm/°C) and slightly higher power per element rating (63mW versus 62.5mW). The seated height differential (0.020" versus 0.022") is negligible for standard PCB assembly processes.

Selection between these parts should be based on supply chain availability, lead time requirements, and established qualification protocols within your organization. Both components are functionally equivalent for isolated 4-resistor network applications requiring 82 Ohm elements in 0804 surface mount packages.

Frequently Asked Questions (FAQ)

Q: Can the 741C083820JP directly replace the CAT10-820J4LF in existing designs?

A: Yes. Both components share identical resistance values, tolerance specifications, circuit configuration, package dimensions, and operating temperature ranges. The mechanical and electrical interfaces are compatible for direct substitution in PCB layouts designed for 0804 isolated resistor networks.

Q: What is the significance of the temperature coefficient difference?

A: The CAT10-820J4LF specifies ±250ppm/°C while the 741C083820JP specifies ±200ppm/°C. The CTS part exhibits tighter temperature stability. For applications with stringent temperature drift requirements, the 741C083820JP provides superior performance. For standard applications, both coefficients are acceptable within typical circuit tolerances.

Q: Are there any height clearance concerns between these parts?

A: The seated height difference is 0.002" (0.05mm), with the 741C083820JP being slightly lower. This minimal variance does not create clearance issues in standard PCB assembly and does not affect component placement or routing.

Q: Do both parts support automotive applications?

A: The CAT10-820J4LF does not list automotive applications in the provided specifications. The 741C083820JP is qualified for Automotive AEC-Q200 applications. If automotive compliance is required, the 741C083820JP is the appropriate selection.

Q: What is the moisture sensitivity rating for both parts?

A: Both components carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions. Standard handling and storage procedures apply without special desiccant or baking requirements.
