Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CAT16-1502F8LF is determined by strict equivalence across the following critical parameters:

• Resistance value: 15kΩ
• Tolerance: ±1%
• Circuit configuration: Isolated, 8-resistor array
• Pin count: 16
• Temperature coefficient: ±200ppm/°C
• Operating temperature range: -55°C to 125°C
• Package type: 2506, Concave, Long Side Terminals
• Mounting technology: Surface Mount

The substitute part 742C1631502FP meets all these criteria, maintaining functional and mechanical compatibility with the original CAT16-1502F8LF specification.

Parameter Comparison

Engineering Selection Recommendations

The 742C1631502FP from CTS Resistor Products is a direct functional equivalent to the obsolete CAT16-1502F8LF. Both components maintain identical electrical specifications across resistance, tolerance, temperature coefficient, and operating temperature range. Both are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements.

The CTS substitute offers the advantage of active product status, ensuring continued availability and supply chain support. The marginal increase in power per element (63mW versus 62.5mW) and the slightly reduced seated height (0.028" versus 0.030") present no functional constraints for standard applications. Dimensional compatibility is maintained across all critical parameters.

Selection of the 742C1631502FP is appropriate for new designs and production continuity where the CAT16-1502F8LF is no longer available.

Frequently Asked Questions (FAQ)

Q: Can the 742C1631502FP be used as a direct replacement for the CAT16-1502F8LF?

A: Yes. Both components share identical electrical specifications, package configuration, pin count, and mounting technology. The substitute meets all functional requirements of the original part.

Q: Are there differences in power rating between these parts?

A: The power per element differs slightly: CAT16-1502F8LF is rated at 62.5mW, while 742C1631502FP is rated at 63mW. This marginal difference does not affect compatibility or performance in standard applications.

Q: Do both parts meet current compliance standards?

A: Yes. Both the CAT16-1502F8LF and 742C1631502FP are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements.

Q: What is the significance of the product status difference?

A: The CAT16-1502F8LF is obsolete, meaning it is no longer manufactured or supported by Bourns Inc. The 742C1631502FP maintains active status, ensuring ongoing availability and supply chain support from CTS Resistor Products.

Q: Are the physical dimensions identical?

A: Dimensions are equivalent across length and width (0.252" x 0.063"). The seated height differs marginally: CAT16-1502F8LF at 0.030" (0.75mm) and 742C1631502FP at 0.028" (0.70mm). This difference does not affect PCB layout or assembly compatibility.

Q: Can these parts be used interchangeably in existing designs?

A: Yes. The electrical and mechanical specifications are equivalent, and both components use the same 2506 package with concave, long side terminals. No design modifications are required for substitution.
