CAT16-103J4GLF Equivalent & Substitute Parts

Part Overview

The CAT16-103J4GLF is a 10k Ohm isolated 4-resistor network array in 1206 (3216 Metric) surface mount package manufactured by Bourns Inc. This component is classified as obsolete, making equivalent substitute parts necessary for ongoing production and maintenance applications. The part delivers 62.5mW power per element with ±5% tolerance and ±200ppm/°C temperature coefficient, suitable for isolated resistor network applications requiring stable performance across -55°C to 125°C operating range.

Substitute Part Grouping Explanation

Substitution eligibility for the CAT16-103J4GLF is determined by strict alignment with the following electrical and mechanical parameters:

Resistance value: 10k Ohm
Tolerance: ±5%
Number of resistors: 4
Circuit type: Isolated
Temperature coefficient: ±200ppm/°C
Package / Case: 1206 (3216 Metric), Concave, Long Side Terminals
Number of pins: 8
Mounting type: Surface Mount
RoHS compliance: ROHS3 Compliant
Moisture sensitivity level: 1 (Unlimited)

All substitute parts listed meet these core requirements. Variations in power per element (62.5mW to 63mW), physical dimensions within the 1206 package specification, and operating temperature upper limits do not preclude substitution when the primary electrical and mechanical parameters align.

Engineering Selection Recommendations

All listed substitute parts are active products with ROHS3 compliance and MSL 1 rating, providing long-term availability and regulatory alignment superior to the obsolete CAT16-103J4GLF.

CAT16-103J4LF is the direct Bourns Inc. equivalent, maintaining identical electrical specifications and operating temperature range while offering active product status and significantly higher inventory availability (299,772 units).

742C083103JP from CTS Resistor Products provides automotive-grade qualification (AEC-Q200) with marginally higher power per element (63mW vs 62.5mW), suitable for applications requiring automotive reliability standards.

EXB-V8V103JV from Panasonic Electronic Components matches all core electrical parameters with active status and substantial inventory depth (643,393 units).

TC164-JR-0710KL from YAGEO extends the operating temperature range to 155°C and carries AEC-Q200 automotive qualification, appropriate for temperature-critical or automotive applications requiring enhanced thermal performance.

Frequently Asked Questions (FAQ)

Q: Can CAT16-103J4LF directly replace CAT16-103J4GLF?

A: Yes. CAT16-103J4LF is the active equivalent from Bourns Inc., matching all electrical specifications (10k Ohm, ±5%, 62.5mW, ±200ppm/°C) and operating temperature range (-55°C to 125°C). The primary difference is product status (active vs. obsolete) and packaging format (Tape & Reel vs. standard packaging).

Q: What is the difference between the substitute parts?

A: All substitutes share identical core electrical parameters (10k Ohm, ±5%, 4 resistors, isolated circuit, ±200ppm/°C). Differences include: manufacturer (Bourns, CTS, Panasonic, YAGEO), power per element (62.5mW or 63mW), operating temperature upper limit (125°C or 155°C), and automotive qualification status (AEC-Q200 for 742C083103JP and TC164-JR-0710KL).

Q: Are all substitutes compatible with the original PCB layout?

A: Yes. All substitutes use the 1206 (3216 Metric) package with concave, long side terminals and 8-pin configuration, maintaining footprint compatibility with designs using CAT16-103J4GLF.

Q: Which substitute should I select for automotive applications?

A: 742C083103JP (CTS) or TC164-JR-0710KL (YAGEO) are qualified to AEC-Q200 automotive standards. TC164-JR-0710KL additionally supports extended operating temperature to 155°C.

Q: Does the 1mW difference in power per element affect substitution?

A: No. The 63mW rating of 742C083103JP versus 62.5mW of other parts represents a margin increase and does not preclude substitution. The component remains within the same functional class for isolated 4-resistor networks.

Q: What is the moisture sensitivity implication?

A: All substitutes carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions. Storage and handling follow standard practices without special desiccant or humidity control requirements.
