RC3225J161CS Equivalent & Substitute Parts

Part Overview

The RC3225J161CS is a 160 Ohm ±5% thick film chip resistor manufactured by Samsung Electro-Mechanics in the 1210 (3225 Metric) package format. This component is rated for 0.333W (1/3W) power dissipation and operates across the temperature range of -55°C to 155°C. The part is currently in active production status with 755 units available in new original inventory. This resistor is designed for general-purpose applications requiring moisture-resistant thick film construction and is fully compliant with RoHS3 and REACH regulations.

Identifying equivalent and substitute parts becomes necessary when the primary part experiences supply constraints, when design requirements demand enhanced performance specifications, or when procurement optimization requires evaluation of alternative manufacturers offering compatible electrical and mechanical characteristics.

Substitute Part Grouping Explanation

Substitution of the RC3225J161CS is permissible with parts meeting the following criteria:

• Identical resistance value: 160 Ohms
• Identical package format: 1210 (3225 Metric)
• Identical composition: Thick Film
• Identical operating temperature range: -55°C to 155°C
• Identical temperature coefficient: ±100ppm/°C
• Identical moisture sensitivity level: MSL 1 (Unlimited)
• Tolerance equal to or tighter than ±5%
• Power rating equal to or greater than 0.333W
• RoHS3 compliance maintained

The AC1210FR-07160RL from YAGEO satisfies all substitution criteria. This part offers improved tolerance specification (±1% versus ±5%) and increased power rating (0.5W versus 0.333W), while maintaining identical resistance, package, composition, temperature characteristics, and regulatory compliance.

Parameter Comparison

Engineering Selection Recommendations

The AC1210FR-07160RL represents a direct electrical and mechanical substitute for the RC3225J161CS. Both components maintain active production status and full regulatory compliance with RoHS3 and REACH requirements.

The YAGEO AC1210FR-07160RL offers enhanced specifications in two areas: tolerance is improved from ±5% to ±1%, and power rating is increased from 0.333W to 0.5W. These improvements provide greater design margin and tighter resistance accuracy without compromising any electrical or mechanical compatibility.

The AC1210FR-07160RL carries AEC-Q200 automotive qualification, which the RC3225J161CS does not specify. This additional certification may be relevant for applications requiring automotive-grade component validation.

Both parts are supplied in identical 1210 (3225 Metric) packages with equivalent physical dimensions and termination configurations, ensuring direct PCB layout compatibility.

Frequently Asked Questions (FAQ)

Q: Can the AC1210FR-07160RL be used as a direct replacement for the RC3225J161CS?

A: Yes. Both components share identical resistance value (160 Ohms), package format (1210), composition (thick film), operating temperature range (-55°C to 155°C), and temperature coefficient (±100ppm/°C). The YAGEO part offers improved tolerance and power rating specifications while maintaining full compatibility.

Q: What are the physical dimension differences between these parts?

A: The RC3225J161CS measures 0.126" L × 0.100" W (3.20mm × 2.55mm) with maximum seated height of 0.026" (0.66mm). The AC1210FR-07160RL measures 0.122" L × 0.102" W (3.10mm × 2.60mm) with maximum seated height of 0.024" (0.60mm). Both dimensions fall within the 1210 package specification and are compatible with standard PCB layouts designed for this package format.

Q: Does the improved tolerance of the AC1210FR-07160RL affect circuit performance?

A: The tighter ±1% tolerance of the AC1210FR-07160RL provides greater resistance accuracy compared to the ±5% tolerance of the RC3225J161CS. This improvement reduces circuit parameter variation and may enhance performance in applications where resistance accuracy is critical.

Q: Are there any thermal performance differences?

A: Both components operate across identical temperature ranges (-55°C to 155°C) with identical temperature coefficients (±100ppm/°C). The AC1210FR-07160RL has a higher power rating (0.5W versus 0.333W), which provides additional thermal margin in power dissipation applications.

Q: What is the significance of the AEC-Q200 rating on the YAGEO part?

A: AEC-Q200 is an automotive industry qualification standard. The AC1210FR-07160RL carries this certification, while the RC3225J161CS does not specify this rating. For non-automotive applications, this difference is not relevant. For automotive applications, the YAGEO part provides validated automotive-grade reliability.

Q: Are both parts available in the same packaging format?

A: The RC3225J161CS is supplied in Tape & Reel (TR) format. The AC1210FR-07160RL is also supplied in Tape & Reel (TR) format. Both are compatible with automated assembly equipment.
