CAY10-330J2LF Equivalent & Substitute Parts

Part Overview

The CAY10-330J2LF is a 33 Ohm isolated 2-resistor network array manufactured by Bourns Inc. in 0404 (1010 Metric) surface mount package. This component is designed for applications requiring matched resistor pairs with controlled temperature coefficients and low power dissipation per element. The part is active in production status with ROHS3 compliance and unlimited moisture sensitivity rating.

Substitute parts are identified when equivalent electrical performance, mechanical compatibility, and regulatory compliance can be maintained across different manufacturers while preserving circuit functionality.

Substitute Part Grouping Explanation

Substitution eligibility for the CAY10-330J2LF is determined by strict equivalence across the following parameters:

Resistance value: 33 Ohm
Tolerance: ±5%
Number of resistors: 2
Circuit type: Isolated
Package / Case: 0404 (1010 Metric), Convex
Mounting type: Surface Mount
Number of pins: 4
Physical dimensions: 0.039" L x 0.039" W (1.00mm x 1.00mm)
RoHS compliance: ROHS3 Compliant
Moisture sensitivity: 1 (Unlimited)

All identified substitute parts meet these core requirements. Variations in temperature coefficient (±200ppm/°C vs ±250ppm/°C), power per element (62.5mW to 63mW), and operating temperature upper limits (125°C to 155°C) represent acceptable performance enhancements that do not compromise circuit compatibility.

Engineering Selection Recommendations

All substitute parts maintain active product status and ROHS3 compliance equivalent to the CAY10-330J2LF. Selection among substitutes should be based on:

CTS 741X043330JP: Offers improved temperature coefficient (±200ppm/°C) with automotive AEC-Q200 qualification and DDR SDRAM/DRAM application support. Maintains identical operating temperature range and power rating.

Panasonic EXB-24V330JX: Provides improved temperature coefficient (±200ppm/°C) with automotive AEC-Q200 qualification. Maintains identical power per element and operating temperature range as the original part.

Stackpole RAVF102DJT33R0: Extends operating temperature range to 155°C with automotive AEC-Q200 qualification and improved temperature coefficient (±200ppm/°C). Suitable for applications requiring higher temperature operation.

YAGEO YC122-JR-0733RL: Extends operating temperature range to 155°C with automotive AEC-Q200 qualification and improved temperature coefficient (±200ppm/°C). Supplied in Cut Tape packaging rather than Tape & Reel format.

Frequently Asked Questions (FAQ)

Q: Can CAY10-330J2LF be directly replaced with any of these substitute parts?

A: Yes. All substitute parts share identical resistance value (33 Ohm), tolerance (±5%), package type (0404 1010 Metric), pin count (4), and physical dimensions. They are mechanically and electrically compatible for direct substitution in surface mount applications.

Q: What is the difference between the temperature coefficients?

A: The CAY10-330J2LF has a temperature coefficient of ±250ppm/°C, while all substitute parts offer ±200ppm/°C. Lower temperature coefficient values indicate better stability across temperature variations, representing an improvement over the original specification.

Q: Are there operating temperature differences?

A: The CAY10-330J2LF, 741X043330JP, and EXB-24V330JX operate from -55°C to 125°C. The RAVF102DJT33R0 and YC122-JR-0733RL extend the upper limit to 155°C, providing additional thermal margin for high-temperature applications.

Q: What packaging format differences exist?

A: The CAY10-330J2LF, 741X043330JP, and EXB-24V330JX are supplied in Tape & Reel (TR) format. The YC122-JR-0733RL is supplied in Cut Tape (CT) format. Both formats are suitable for automated assembly; format selection depends on production line equipment compatibility.

Q: Do all parts have automotive qualification?

A: The CAY10-330J2LF does not specify automotive qualification. The 741X043330JP, EXB-24V330JX, RAVF102DJT33R0, and YC122-JR-0733RL all carry AEC-Q200 automotive qualification, making them suitable for automotive applications requiring this certification.

Q: Are all parts ROHS3 compliant?

A: Yes. All parts listed are ROHS3 compliant with unlimited moisture sensitivity rating (MSL 1), meeting current environmental and regulatory requirements.
