Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CAT16-182J4LF is determined by strict alignment of the following parameters:

• Resistance value: 1.8k Ohm
• Tolerance: ±5%
• Number of resistors: 4
• Circuit type: Isolated
• Package / Case: 1206 (3216 Metric), Concave, Long Side Terminals
• Number of pins: 8
• Mounting type: Surface Mount
• RoHS compliance: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

All three substitute parts meet these core criteria. Variations in power per element (62.5mW vs 63mW) and operating temperature range extensions are within acceptable engineering tolerances for this component category and do not preclude substitution.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts are classified as Active product status and maintain full ROHS3 compliance and REACH unaffected status, matching the original CAT16-182J4LF specification.

The TC164-JR-071K8L from YAGEO provides an extended operating temperature range of -55°C to 155°C compared to the standard -55°C to 125°C range, with AEC-Q200 automotive qualification. This part is suitable for applications requiring enhanced thermal performance or automotive-grade reliability.

The 742C083182JP from CTS Resistor Products and EXB-V8V182JV from Panasonic Electronic Components maintain identical electrical specifications to the original part and are suitable for general-purpose applications.

Frequently Asked Questions (FAQ)

Q: Can I substitute the CAT16-182J4LF with any of these parts on my PCB?

A: Yes. All three substitute parts share identical resistance value (1.8k Ohm), tolerance (±5%), circuit configuration (4-resistor isolated network), package type (1206 with concave long side terminals), pin count (8), and mounting method (surface mount). They are electrically and mechanically interchangeable.

Q: What is the difference between the substitute parts?

A: The primary differences are manufacturer, power per element rating (62.5mW vs 63mW), and operating temperature range. The TC164-JR-071K8L extends to 155°C and includes AEC-Q200 automotive qualification. The 742C083182JP has a marginally higher power rating of 63mW. These variations do not affect substitution eligibility for standard applications.

Q: Does the package dimension variation affect PCB compatibility?

A: The package dimensions vary slightly between parts (width ranges from 0.061" to 0.063", height from 0.024" to 0.028"), but all conform to the 1206 (3216 Metric) standard with concave long side terminals. These variations are within standard PCB design tolerances and do not require layout modifications.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All substitute parts are ROHS3 compliant with Moisture Sensitivity Level 1 (Unlimited), matching the original CAT16-182J4LF specification.

Q: Which substitute should I choose for automotive applications?

A: The TC164-JR-071K8L is qualified to AEC-Q200 automotive standards and is the appropriate selection for automotive applications requiring formal qualification documentation.
