Key Parameters

Substitute Part Grouping Explanation

Substitution of the CAY17-153JALF is determined by the following mandatory parameters:

• Resistance value: 15kΩ
• Tolerance: ±5%
• Number of resistors: 8
• Circuit type: Bussed
• Number of pins: 10
• Package: 1206 (3216 Metric), Convex, Long Side Terminals
• Mounting type: Surface Mount
• Physical dimensions: 0.126" L x 0.063" W (3.20mm x 1.60mm)
• Compliance: ROHS3 Compliant, MSL 1

The CTS Resistor Products 746X101153JP meets all mandatory substitution criteria. Variations in power per element, temperature coefficient, and operating temperature range do not preclude substitution when the application requirements fall within the substitute part's specifications.

Parameter Comparison

Engineering Selection Recommendations

The 746X101153JP from CTS Resistor Products is an active substitute for the obsolete CAY17-153JALF. Both components are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements. The CTS part offers the advantage of active product status with established supply chain availability.

Selection between these parts should account for the following parameter differences:

• The CAY17-153JALF supports higher power dissipation per element (62.5mW vs. 31mW)
• The CAY17-153JALF operates to 155°C maximum; the 746X101153JP operates to 125°C maximum
• The CAY17-153JALF exhibits a higher temperature coefficient (±250ppm/°C vs. ±200ppm/°C)
• The 746X101153JP has a slightly greater seated height (0.028" vs. 0.024")

Applications specified for the 746X101153JP include DDR SDRAM, DRAM, and MDDR memory systems. Substitution is appropriate when the application's thermal, power, and temperature stability requirements fall within the 746X101153JP specifications.

Frequently Asked Questions (FAQ)

Q: Can the 746X101153JP replace the CAY17-153JALF in all applications?

A: The 746X101153JP is mechanically and electrically compatible based on matching resistance, tolerance, pin count, and package specifications. However, applications requiring operation above 125°C or power dissipation exceeding 31mW per element require verification against the 746X101153JP datasheet.

Q: What is the significance of the power per element difference?

A: Power per element rating indicates the maximum continuous power dissipation capability of each resistor in the array. The CAY17-153JALF supports 62.5mW per element, while the 746X101153JP supports 31mW per element. Applications with lower power requirements are unaffected by this difference.

Q: Are there packaging differences between these parts?

A: Both parts use the 1206 (3216 Metric) package with convex, long side terminals. The seated height differs slightly: CAY17-153JALF is 0.024" maximum, while 746X101153JP is 0.028" maximum. This difference is negligible for most PCB assembly applications.

Q: What does the bussed circuit type mean?

A: A bussed resistor network has a common connection point (bus) shared among all resistors, reducing the number of required pins compared to individual resistors. The 10-pin configuration accommodates 8 resistors with a common bus connection.

Q: Are both parts compliant with current regulations?

A: Yes. Both the CAY17-153JALF and 746X101153JP are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic components.
