Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CAT16-1002F4LF is determined by the following critical parameters:

• Resistance value: 10kΩ (exact match required)
• Number of resistors: 4 (exact match required)
• Circuit type: Isolated (exact match required)
• Package / Case: 1206 (3216 Metric), Concave, Long Side Terminals (exact match required)
• Number of pins: 8 (exact match required)
• Operating temperature range: -55°C ~ 125°C (exact match required)
• Temperature coefficient: ±200ppm/°C (exact match required)

The CTS Resistor Products part 742C083103JP meets all critical substitution criteria. Tolerance variation (±1% vs ±5%) and power per element differences (62.5mW vs 63mW) fall within acceptable substitution parameters for this component category.

Parameter Comparison

Engineering Selection Recommendations

Both the CAT16-1002F4LF and 742C083103JP maintain active product status with full regulatory compliance. The CAT16-1002F4LF offers tighter tolerance specification (±1%) compared to the CTS substitute (±5%). The 742C083103JP provides marginally higher power per element rating (63mW vs 62.5mW) and is qualified for automotive AEC-Q200 applications. Both parts carry identical RoHS3 compliance, unlimited moisture sensitivity rating, and REACH unaffected status. Selection between these parts depends on tolerance requirements and application-specific compliance needs.

Frequently Asked Questions (FAQ)

Q: Can the 742C083103JP replace the CAT16-1002F4LF in all applications?

A: The 742C083103JP meets all critical electrical and mechanical parameters. However, the tolerance difference (±5% vs ±1%) must be evaluated against circuit requirements. Applications with strict tolerance specifications may require the CAT16-1002F4LF.

Q: Are there package compatibility concerns between these parts?

A: Both parts use identical 1206 (3216 Metric) packages with concave, long side terminals. The maximum seated height differs by 0.004" (0.10mm), which does not affect PCB layout or assembly compatibility for standard surface mount processes.

Q: Do both parts meet automotive qualification requirements?

A: The 742C083103JP carries AEC-Q200 automotive qualification. The CAT16-1002F4LF product status does not specify automotive qualification in the provided data.

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

A: Both parts maintain ±200ppm/°C temperature coefficient across the -55°C to 125°C operating range, ensuring stable resistance values under thermal stress.

Q: Are there supply chain considerations for these substitutes?

A: The 742C083103JP maintains significantly higher inventory availability (505,830 pcs vs 3,852 pcs), which may impact lead time and procurement strategy.
