Key Parameters

Substitute Part Grouping Explanation

Substitution of the CAT16-101J8LF is determined by strict equivalence across the following parameters:

• Resistance value: 100 Ohm
• Tolerance: ±5%
• Number of resistor elements: 8
• Circuit configuration: Isolated
• Package designation: 2506, Concave, Long Side Terminals
• Pin count: 16
• Temperature coefficient: ±200ppm/°C
• Operating temperature range: -55°C to 125°C
• Mounting technology: Surface Mount
• Regulatory compliance: ROHS3 Compliant, REACH Unaffected

The 742C163101JP from CTS Resistor Products meets all these criteria and qualifies as a direct substitute. Minor variations in power per element (63mW versus 62.5mW) and seated height (0.028" versus 0.030") remain within acceptable mechanical and thermal tolerances for this package category.

Parameter Comparison

Engineering Selection Recommendations

The 742C163101JP is a qualified substitute for the obsolete CAT16-101J8LF based on electrical and mechanical equivalence. Both components maintain identical resistance values, tolerance specifications, temperature coefficients, and operating ranges. Both are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements.

The CTS part offers the advantage of active product status with substantial inventory availability (81,559 pieces), ensuring supply chain continuity. The marginal increase in power per element (63mW versus 62.5mW) and reduction in seated height (0.028" versus 0.030") present no functional constraints for standard circuit applications. Both components are packaged identically in the 2506 format with concave, long side terminals, ensuring mechanical compatibility in existing PCB layouts.

Frequently Asked Questions (FAQ)

Q: Can the 742C163101JP replace the CAT16-101J8LF in existing designs?

A: Yes. Both components share identical electrical specifications (100 Ohm, ±5% tolerance, ±200ppm/°C temperature coefficient, -55°C to 125°C operating range) and mechanical packaging (2506, 16-pin surface mount). The substitute is electrically and mechanically interchangeable.

Q: What is the significance of the power per element difference (62.5mW vs. 63mW)?

A: This 0.5mW difference is negligible for circuit design purposes. Both ratings exceed typical application requirements for 100 Ohm resistor networks in standard configurations.

Q: Are there any PCB layout considerations when switching to the 742C163101JP?

A: No. Both components use identical footprints and package dimensions (0.252" L x 0.063" W). The 0.002" difference in seated height (0.028" versus 0.030") is within standard PCB assembly tolerances and requires no layout modifications.

Q: What compliance certifications apply to the substitute part?

A: The 742C163101JP is ROHS3 compliant and REACH unaffected, matching the regulatory status of the original CAT16-101J8LF.

Q: Why is the original part listed as obsolete?

A: The CAT16-101J8LF has been discontinued by Bourns Inc. The 742C163101JP from CTS Resistor Products provides functional continuity for applications requiring 8-element 100 Ohm isolated resistor networks in 2506 surface mount packages.
