CAY16-100J4 Equivalent & Substitute Parts

Part Overview

The CAY16-100J4 is a 10 Ohm isolated 4-resistor network array in 1206 surface mount package manufactured by Bourns Inc. This part is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and procurement. The CAY16-100J4 delivers 62.5mW power per element with ±5% tolerance and ±200ppm/°C temperature coefficient across an operating range of -55°C to 125°C. Direct substitutes and upgraded alternatives are available from multiple manufacturers with identical or enhanced electrical characteristics.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the CAY16-100J4 is determined by the following critical parameters: resistance value (10 Ohm), tolerance (±5%), circuit type (isolated), number of resistors (4), package type (1206 with convex long side terminals), number of pins (8), temperature coefficient (±200ppm/°C), and moisture sensitivity level (MSL 1). Power per element and operating temperature range define upgrade categories.

Direct Substitute Category: Parts maintaining identical electrical specifications and power ratings (62.5mW per element) with -55°C to 125°C operating range.

Upgraded Substitute Category: Parts with enhanced power ratings (100mW per element) or extended operating temperature ranges (-55°C to 155°C), suitable for applications requiring higher thermal or power margins.

Parameter Comparison

Engineering Selection Recommendations

CAY16-100J4LF is the direct equivalent substitute from Bourns Inc., maintaining identical electrical specifications and power ratings while offering active product status and ROHS3 compliance. This part is recommended for designs requiring no performance changes from the original CAY16-100J4.

RAVF164DJT10R0 from Stackpole Electronics Inc. is an upgraded substitute offering 100mW power per element (versus 62.5mW) and extended operating temperature range to 155°C. This part carries AEC-Q200 automotive qualification and ROHS3 compliance, suitable for applications requiring enhanced thermal performance or automotive-grade reliability.

YC164-JR-0710RL and YC164-JR-1010RL from YAGEO are upgraded substitutes with extended operating temperature range to 155°C and ROHS3 compliance. YC164-JR-0710RL is qualified for automotive AEC-Q200 and DDRAM/SDRAM applications. Both parts maintain 62.5mW power per element and are suitable for designs requiring higher temperature operation or automotive-grade components.

Selection between direct and upgraded substitutes depends on application requirements for operating temperature range, power dissipation margin, and compliance certifications. All substitute parts maintain identical package geometry and pin configuration for direct PCB compatibility.

Frequently Asked Questions (FAQ)

Q: Can CAY16-100J4LF be used as a direct replacement for CAY16-100J4?

A: Yes. CAY16-100J4LF maintains identical electrical specifications including 10 Ohm resistance, ±5% tolerance, 62.5mW power per element, ±200ppm/°C temperature coefficient, and -55°C to 125°C operating range. Package geometry and pin configuration are identical. The primary difference is active product status and ROHS3 compliance.

Q: What is the difference between the direct substitute and upgraded substitutes?

A: Direct substitute CAY16-100J4LF matches all original specifications. Upgraded substitutes (RAVF164DJT10R0, YC164-JR-0710RL, YC164-JR-1010RL) extend operating temperature to 155°C and offer ROHS3 compliance. RAVF164DJT10R0 additionally provides 100mW power per element. These upgrades provide design margin for thermal or power-intensive applications.

Q: Are all substitute parts in the same 1206 package?

A: Yes. All substitute parts use 1206 (3216 Metric) package with convex long side terminals, 8 pins, and identical footprint dimensions (0.126" L x 0.063" W / 3.20mm x 1.60mm). Height varies slightly: CAY16-100J4 and CAY16-100J4LF are 0.024" (0.60mm) maximum; YC164 series parts are 0.028" (0.70mm) maximum. This minor height difference does not affect PCB assembly compatibility.

Q: Which substitute is recommended for automotive applications?

A: RAVF164DJT10R0 and YC164-JR-0710RL carry automotive qualifications. RAVF164DJT10R0 holds AEC-Q200 qualification with extended temperature range to 155°C and 100mW power per element. YC164-JR-0710RL holds AEC-Q200 qualification with extended temperature range to 155°C. Both are suitable for automotive-grade designs.

Q: What is the moisture sensitivity level for all parts?

A: All parts maintain MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.

Q: Are all substitute parts ROHS3 compliant?

A: CAY16-100J4LF, RAVF164DJT10R0, and YC164-JR-0710RL are ROHS3 compliant. RoHS status for YC164-JR-1010RL is not specified in available data. Verify RoHS compliance requirements with your supplier for YC164-JR-1010RL if ROHS3 certification is mandatory.
