RC0603F184CS Equivalent & Substitute Parts

Part Overview

The RC0603F184CS is a 180 kOhms ±1% thick film chip resistor manufactured by Samsung Electro-Mechanics in the 0201 (0603 Metric) package format. This component is rated for 0.05W (1/20W) power dissipation and is designed for moisture-resistant applications across industrial and commercial temperature ranges. The part maintains Active product status with 754 units currently in stock.

Substitute parts become necessary when the primary manufacturer experiences supply constraints, discontinuation, or when design requirements permit functional equivalents that meet identical electrical and mechanical specifications.

Current inventory of 1524 units available for immediate use
Identical electrical specifications and package format ensure PCB compatibility without redesign
ROHS3 compliance and REACH unaffected status maintain regulatory requirements

Selection between these parts should prioritize supply chain continuity and long-term availability requirements. Both parts satisfy identical functional and compliance criteria.

Frequently Asked Questions (FAQ)

Q: Can MCR006YRTF1803 be used as a direct replacement for RC0603F184CS on existing PCBs?

A: Yes. Both parts share identical package dimensions (0201/0603 Metric), footprint requirements, and electrical specifications. No PCB layout modifications are required.

Q: Are there differences in moisture handling between these parts?

A: No. Both parts carry MSL 1 (Unlimited) rating, indicating identical moisture sensitivity levels and storage requirements.

Q: Does the discontinued status of MCR006YRTF1803 affect its performance?

A: No. Discontinued status refers only to manufacturer production and distribution decisions. Electrical performance, reliability, and compliance characteristics remain unchanged. However, future availability may be limited.

Q: What is the significance of the ±250ppm/°C temperature coefficient?

A: This specification defines resistance value drift across the -55°C to 125°C operating range. Both parts maintain identical temperature stability characteristics.

Q: Are both parts suitable for high-reliability applications?

A: Both parts meet ROHS3 compliance and carry MSL 1 ratings. Selection should be based on supply chain requirements and long-term availability needs specific to the application.

Q: Can these parts be used interchangeably in production?

A: Yes, provided supply chain documentation and traceability requirements are satisfied. Electrical and mechanical equivalence is complete.
