CAY16-100J2LF Equivalent & Substitute Parts

Part Overview

The CAY16-100J2LF is a 2-resistor isolated network array manufactured by Bourns Inc., featuring 10 Ohm resistance with ±5% tolerance and 62.5mW power per element in a 0606 surface mount package. This component is classified as obsolete, making equivalent substitute parts necessary for ongoing design support and procurement continuity. The part operates across -55°C to 125°C and complies with ROHS3 and REACH standards.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CAY16-100J2LF is determined by strict equivalence across the following parameters: 10 Ohm resistance value, ±5% tolerance, 2-resistor isolated configuration, 62.5mW power per element, ±200ppm/°C temperature coefficient, 4-pin count, 0606 package footprint, and surface mount technology. All identified substitutes meet these core electrical and mechanical specifications. Variations in operating temperature range, height-seated maximum, and product status are noted but do not disqualify substitution where the primary functional parameters align.

Parameter Comparison

Engineering Selection Recommendations

Both MNR12ERAPJ100 and RAVF162DJT10R0 satisfy the electrical and mechanical requirements for direct substitution of the CAY16-100J2LF. All three parts maintain ROHS3 compliance and REACH unaffected status.

The MNR12ERAPJ100 (Rohm Semiconductor) provides the closest physical profile with a height-seated maximum of 0.022" (0.55mm), slightly lower than the original 0.024" (0.60mm). This part is discontinued at DiGi Electronics but maintains full electrical equivalence.

The RAVF162DJT10R0 (Stackpole Electronics Inc) is the only active product among the three and offers an extended operating temperature range to 155°C. The package designation includes "Long Side Terminals" and a height-seated maximum of 0.026" (0.65mm), which remains within acceptable tolerance for most PCB layouts designed for the original 0606 footprint.

Frequently Asked Questions (FAQ)

Q: Can MNR12ERAPJ100 and RAVF162DJT10R0 be used interchangeably with CAY16-100J2LF?

A: Yes. Both substitute parts match the critical electrical parameters: 10 Ohm resistance, ±5% tolerance, 2-resistor isolated configuration, 62.5mW power per element, ±200ppm/°C temperature coefficient, and 4-pin 0606 surface mount package. Physical height variations (0.022" to 0.026") are minor and compatible with standard PCB assembly processes.

Q: What is the primary difference between the two substitute options?

A: The RAVF162DJT10R0 maintains active product status and supports an extended operating temperature range to 155°C, compared to the original specification of 125°C. The MNR12ERAPJ100 offers a lower profile height but is discontinued at DiGi Electronics. Both are electrically equivalent.

Q: Are there compliance or certification concerns with substitution?

A: No. All three parts are ROHS3 compliant, REACH unaffected, and carry identical moisture sensitivity levels (MSL 1, Unlimited). Substitution does not introduce compliance risks.

Q: Does the "Long Side Terminals" designation on RAVF162DJT10R0 affect compatibility?

A: No. This designation describes the terminal configuration within the 0606 package footprint and does not affect PCB pad layout or assembly compatibility for designs originally specified for CAY16-100J2LF.

Q: Which substitute should be selected for new designs?

A: Selection depends on procurement availability and temperature requirements. RAVF162DJT10R0 is recommended for applications requiring active product status and extended temperature range support. MNR12ERAPJ100 is suitable where inventory availability permits and operating temperature does not exceed 155°C.
