CAT16-151J8LF Equivalent & Substitute Parts

Part Overview

The CAT16-151J8LF is an 8-resistor isolated network array manufactured by Bourns Inc., featuring 150 Ohm resistors with ±5% tolerance in a 2506 surface mount package. This component is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing production support and design continuity. The part delivers 62.5mW power per element across an operating temperature range of -55°C to 125°C, with ±200ppm/°C temperature coefficient stability.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CAT16-151J8LF is determined by strict alignment across the following critical parameters:

• Resistance value: 150 Ohms
• Tolerance: ±5%
• Number of resistors: 8 elements
• Circuit configuration: Isolated topology
• Pin count: 16 pins
• Package designation: 2506, Concave, Long Side Terminals
• Temperature coefficient: ±200ppm/°C
• Operating temperature range: -55°C to 125°C
• RoHS3 compliance status

The substitute part 742C163151JP (CTS Resistor Products) meets all mandatory electrical and mechanical parameters. While the substitute delivers 63mW power per element compared to the original 62.5mW, this represents a functional enhancement within the isolated resistor network category and does not restrict substitution. Both parts maintain identical package geometry, pin configuration, and environmental specifications.

Parameter Comparison

Engineering Selection Recommendations

The 742C163151JP from CTS Resistor Products is a direct functional equivalent to the obsolete CAT16-151J8LF. Both components maintain ROHS3 compliance and identical environmental ratings. The CTS substitute carries active product status, ensuring continued availability and supply chain stability compared to the Bourns obsolete designation. The marginal increase in power dissipation per element (63mW versus 62.5mW) represents a performance enhancement that does not compromise circuit operation within the specified temperature range. Pin-for-pin compatibility and identical package geometry enable direct board-level substitution without layout modification.

Frequently Asked Questions (FAQ)

Q: Can the 742C163151JP replace the CAT16-151J8LF in existing designs?

A: Yes. Both components share identical electrical specifications (150 Ohm, ±5% tolerance, ±200ppm/°C), pin count (16), circuit topology (isolated), and package geometry (2506, Concave, Long Side Terminals). Direct substitution is supported without circuit redesign.

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

A: The CTS substitute provides marginally higher power dissipation capability. This represents a functional enhancement and does not restrict substitution. Both values fall within the operational envelope for isolated resistor networks in this package class.

Q: Are there packaging differences between these parts?

A: Both components use identical 2506 package geometry with concave, long side terminals. The CAT16-151J8LF is supplied in standard packaging, while the 742C163151JP is available in Tape & Reel format. This difference affects supply chain logistics but not electrical or mechanical compatibility.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the CAT16-151J8LF and 742C163151JP are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99. Moisture sensitivity level is identical at MSL 1 (Unlimited) for both components.

Q: Why is the CAT16-151J8LF listed as obsolete?

A: Obsolescence reflects Bourns Inc. product lifecycle decisions. The CTS 742C163151JP maintains active status, providing continuity for applications requiring 150 Ohm isolated 8-resistor networks in 2506 surface mount packages.
