Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CAT16-820J4LF is determined by strict adherence to the following electrical and mechanical parameters:

Critical Matching Parameters:

• Resistance value: 82 Ohm
• Tolerance: ±5%
• Number of resistor elements: 4
• Circuit configuration: Isolated
• Pin count: 8
• Package type: 1206 (3216 Metric) with concave, long side terminals
• Temperature coefficient: ±200ppm/°C
• Mounting technology: Surface mount

Acceptable Variation Parameters:

• Power per element: 62.5mW to 63mW (within component thermal design margins)
• Operating temperature range: Minimum -55°C, maximum 125°C or higher
• Physical dimensions: Within standard 1206 package tolerances

All identified substitute parts maintain these specifications and are qualified for direct replacement in the same circuit application without design modification.

Engineering Selection Recommendations

All substitute parts listed maintain active product status with full regulatory compliance. Selection among CAT16-820J4LF, 742C083820JP, EXB-V8V820JV, and TC164-JR-0782RL is based on availability, supply chain considerations, and application-specific temperature requirements.

For applications operating within the -55°C to 125°C range, all four parts are functionally equivalent. The TC164-JR-0782RL from YAGEO provides extended upper temperature capability to 155°C, suitable for higher thermal environment applications.

The 742C083820JP from CTS Resistor Products specifies 63mW power per element compared to 62.5mW in other variants, representing a marginal increase within acceptable thermal design margins for this package class.

All parts carry ROHS3 compliance, unlimited moisture sensitivity rating (MSL 1), and REACH unaffected status, meeting current environmental and regulatory requirements for industrial and commercial applications.

Frequently Asked Questions (FAQ)

Q: Can CAT16-820J4LF be replaced with 742C083820JP? A: Yes. Both parts feature 82 Ohm ±5% isolated 4-resistor networks in 1206 package with 8 pins, ±200ppm/°C temperature coefficient, and identical operating temperature range. The 0.5mW difference in power per element (63mW vs 62.5mW) is within acceptable thermal design margins for this package class.

Q: What is the difference between EXB-V8V820JV and TC164-JR-0782RL? A: Both are direct electrical equivalents with identical resistance, tolerance, and temperature coefficient specifications. The primary difference is operating temperature range: EXB-V8V820JV operates -55°C to 125°C, while TC164-JR-0782RL extends to 155°C. Select TC164-JR-0782RL for applications requiring higher temperature operation.

Q: Are all substitute parts in the same physical package? A: Yes. All four parts use 1206 (3216 Metric) surface mount package with concave, long side terminals and 8-pin configuration. Physical dimensions are within standard package tolerances, ensuring PCB footprint compatibility.

Q: Do substitute parts require design changes? A: No. All substitute parts maintain identical electrical specifications, pin configuration, and package footprint. Direct substitution is possible without circuit design modification.
