• Identical package designation: 0606, Concave
• Identical mounting type: Surface Mount
• Identical physical dimensions: 0.063" L x 0.063" W (1.60mm x 1.60mm)
• Equivalent power rating: 63mW per element (compared to 62.5mW)
• Matching compliance standards: ROHS3 Compliant, REACH Unaffected

Parameter Comparison

Engineering Selection Recommendations

The 742C043100JP is a qualified direct substitute for the obsolete CAT16-100J2LF. Both components meet ROHS3 compliance and REACH requirements. The CTS part maintains active product status, ensuring continued availability and supply chain reliability. The marginal difference in power rating (63mW versus 62.5mW) and seated height (0.028" versus 0.030") presents no functional impact on circuit performance. The CTS component is suitable for applications requiring automotive AEC-Q200 qualification, DDR SDRAM, DRAM, and MDDR compatibility.

Frequently Asked Questions (FAQ)

Q: Can the 742C043100JP directly replace the CAT16-100J2LF without PCB modification?

A: Yes. Both components share identical package designation (0606, Concave), pin count (4), and physical dimensions (1.60mm x 1.60mm). The seated height difference of 0.002" (0.05mm) is negligible for standard PCB assembly processes.

Q: Are there electrical performance differences between these parts?

A: No. Both components deliver identical resistance (10 Ohm), tolerance (±5%), temperature coefficient (±200ppm/°C), and operating temperature range (-55°C to 125°C). The power rating difference (63mW versus 62.5mW) is within normal manufacturing variation and presents no functional distinction.

Q: What is the primary reason for substitution?

A: The CAT16-100J2LF is classified as obsolete. The 742C043100JP maintains active product status, ensuring long-term availability and supply continuity.

Q: Are compliance certifications equivalent?

A: Yes. Both components are ROHS3 compliant and REACH unaffected, meeting identical regulatory requirements.

Q: Does the CTS part support automotive applications?

A: Yes. The 742C043100JP is qualified for automotive AEC-Q200 applications, DDR SDRAM, DRAM, and MDDR environments.
