Engineering Selection Recommendations

All listed substitute parts are active production components with full RoHS3 compliance and MSL 1 rating, making them suitable for direct replacement of the obsolete CAT16-330J4GLF.

CAT16-330J4LF is the primary substitute, manufactured by Bourns Inc. with identical electrical specifications and packaging. This part maintains the original design lineage and is available in Cut Tape and Digi-Reel packaging formats.

742C083330JP (CTS Resistor Products) and EXB-V8V330JV (Panasonic Electronic Components) are functionally equivalent alternatives with active product status. The 742C083330JP includes automotive AEC-Q200 qualification and is specified for DDR SDRAM and DRAM applications. Both parts deliver equal or superior power dissipation capability.

TC164-JR-0733RL (YAGEO) extends the operating temperature range to -55°C ~ 155°C and carries automotive AEC-Q200 qualification with DDRAM and SDRAM application history. This part is suitable for applications requiring extended temperature performance.

Selection should prioritize availability, lead time, and packaging format requirements. All parts are electrically and mechanically interchangeable within the specified parameters.

Frequently Asked Questions (FAQ)

Q: Can CAT16-330J4LF directly replace CAT16-330J4GLF on existing PCBs?

A: Yes. Both parts share identical electrical specifications (33 Ohm, ±5%, 62.5mW per element, ±200ppm/°C) and package configuration (1206 with 8 pins). The CAT16-330J4LF is the active production equivalent and requires no design modifications.

Q: What is the difference between the Bourns CAT16 series parts and the CTS 742C083330JP?

A: Electrical performance is equivalent across resistance, tolerance, temperature coefficient, and power rating. The 742C083330JP offers automotive AEC-Q200 qualification and slightly higher power per element (63mW vs 62.5mW). Physical dimensions vary slightly within 1206 package tolerances.

Q: Is TC164-JR-0733RL suitable for applications requiring extended temperature operation?

A: Yes. The TC164-JR-0733RL operates from -55°C to 155°C, exceeding the standard -55°C to 125°C range. It carries automotive AEC-Q200 qualification and is specified for DDRAM and SDRAM applications.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating, meeting current environmental and reliability standards.

Q: What packaging formats are available for these substitute parts?

A: CAT16-330J4LF is available in Cut Tape (CT) and Digi-Reel format. 742C083330JP and TC164-JR-0733RL are supplied in Tape & Reel (TR) format. EXB-V8V330JV is available in Tape & Reel (TR) format. Packaging selection depends on production volume and assembly requirements.

Q: Can these parts be used interchangeably in automotive applications?

A: 742C083330JP and TC164-JR-0733RL carry AEC-Q200 automotive qualification. CAT16-330J4LF and EXB-V8V330JV do not specify automotive qualification but meet equivalent electrical and reliability standards. Application requirements should determine automotive-qualified part selection.
