CAT16-331J4GLF Equivalent & Substitute Parts

Part Overview

The CAT16-331J4GLF is a 330 Ohm isolated 4-resistor network array in 1206 (3216 Metric) surface mount package manufactured by Bourns Inc. This component is classified as obsolete, necessitating identification of active equivalent parts for ongoing production and maintenance applications. The part delivers 62.5mW power per element with ±5% tolerance and ±200ppm/°C temperature coefficient, suitable for general-purpose resistor network applications requiring isolated circuit topology.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CAT16-331J4GLF is determined by strict equivalence across the following parameters: 330 Ohm resistance value, ±5% tolerance, 4-resistor isolated configuration, 8-pin count, 1206 (3216 Metric) package with concave long side terminals, surface mount mounting type, ±200ppm/°C temperature coefficient, and ROHS3 compliance. All identified substitute parts meet these core electrical and mechanical requirements. Variations in power per element (62.5mW vs. 63mW), physical dimensions within the 1206 package specification, and extended operating temperature ranges represent acceptable engineering tolerances that do not preclude substitution.

Parameter Comparison

Engineering Selection Recommendations

All four substitute parts are active products with ROHS3 compliance and MSL 1 rating, making them suitable replacements for the obsolete CAT16-331J4GLF. The CAT16-331J4LF represents the direct Bourns equivalent with identical electrical specifications and packaging. The 742C083331JP from CTS Resistor Products and TC164-JR-07330RL from YAGEO both support automotive AEC-Q200 applications, providing enhanced reliability for demanding environments. The EXB-V8V331JV from Panasonic offers equivalent performance with general-purpose application suitability. Selection should prioritize product availability, supply chain continuity, and application-specific requirements such as automotive qualification when applicable.

Frequently Asked Questions (FAQ)

Q: Can CAT16-331J4LF directly replace CAT16-331J4GLF? A: Yes. CAT16-331J4LF is the active equivalent from Bourns Inc. with identical electrical parameters, tolerance, temperature coefficient, and 1206 package specification. The primary difference is product status (active vs. obsolete) and packaging format (Tape & Reel vs. alternative).

Q: What is the difference between 62.5mW and 63mW power per element? A: Both values fall within acceptable engineering tolerance for this component category. The 742C083331JP specification of 63mW represents a negligible variation that does not affect substitution eligibility or circuit performance.

Q: Are the CTS and YAGEO parts suitable for automotive applications? A: Yes. Both 742C083331JP and TC164-JR-07330RL carry AEC-Q200 automotive qualification. The TC164-JR-07330RL additionally supports extended operating temperature to 155°C, providing margin for high-temperature automotive environments.

Q: Do all substitute parts use the same 1206 package? A: All parts conform to 1206 (3216 Metric) package specification with concave long side terminals and 8-pin configuration. Minor dimensional variations within package tolerance (height 0.024" to 0.028") do not affect PCB layout or assembly compatibility.

Q: What is the significance of MSL 1 rating? A: MSL 1 (Unlimited) indicates these components have unlimited shelf life and require no special moisture control during storage or handling, simplifying inventory management and reducing component degradation risk.
