CAT16-273J2LF Equivalent & Substitute Parts

Part Overview

The CAT16-273J2LF is a 2-resistor network array manufactured by Bourns Inc., featuring 27kΩ resistors with ±5% tolerance in a 0606 surface mount package. This component is classified as obsolete, making equivalent substitutes necessary for ongoing production and maintenance applications. The isolated circuit configuration with 62.5mW power per element and ±200ppm/°C temperature coefficient serves applications requiring precision resistor networks in compact form factors.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the CAT16-273J2LF is determined by strict equivalence across the following parameters:

• Resistance value: 27kΩ
• Tolerance: ±5%
• Number of resistors: 2
• Circuit configuration: Isolated
• Power per element: 62.5mW
• Temperature coefficient: ±200ppm/°C
• Operating temperature range: -55°C to 125°C
• Package: 0606, Concave surface mount
• Pin count: 4
• Compliance: ROHS3, MSL 1

The EXB-V4V273JV from Panasonic Electronic Components meets all specified parameters and qualifies as a direct substitute. The primary distinction is product status: the original CAT16-273J2LF is obsolete, while the EXB-V4V273JV maintains active production status.

Parameter Comparison

Engineering Selection Recommendations

The EXB-V4V273JV is the qualified substitute for the obsolete CAT16-273J2LF. Both components maintain identical electrical specifications and package dimensions, with the Panasonic part offering the advantage of active production status and higher inventory availability (45,714 units versus 1,052 units).

Both parts satisfy ROHS3 compliance and MSL 1 moisture sensitivity requirements. The seated height difference of 0.002" (0.05mm) between the two parts is negligible for standard PCB assembly processes and does not affect functional performance or board layout compatibility.

Selection of the EXB-V4V273JV eliminates obsolescence risk while maintaining full electrical and mechanical compatibility with existing designs.

Frequently Asked Questions (FAQ)

Q: Can the EXB-V4V273JV replace the CAT16-273J2LF in existing designs?

A: Yes. Both components share identical electrical parameters (27kΩ, ±5% tolerance, 62.5mW per element, ±200ppm/°C), circuit configuration (isolated), operating temperature range (-55°C to 125°C), and package specifications (0606, Concave, 4-pin surface mount). The 0.002" height difference is within standard PCB assembly tolerances.

Q: Why is the CAT16-273J2LF listed as obsolete?

A: Obsolete status indicates the manufacturer has discontinued production. The EXB-V4V273JV provides functional equivalence with active production support.

Q: Are there packaging differences between these parts?

A: The CAT16-273J2LF is available in standard packaging, while the EXB-V4V273JV is supplied in Tape & Reel (TR) format. Both are 0606 surface mount packages suitable for automated assembly.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the CAT16-273J2LF and EXB-V4V273JV are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity ratings. Both are REACH Unaffected and classified as EAR99 for export purposes.

Q: What is the temperature coefficient significance?

A: The ±200ppm/°C temperature coefficient is identical for both parts, ensuring equivalent performance across the -55°C to 125°C operating range. This specification determines resistor value stability over temperature variations.
