RC1005F180CS Equivalent & Substitute Parts

Part Overview

The RC1005F180CS is an 18 Ohm ±1% thick film chip resistor manufactured by Samsung Electro-Mechanics in 0402 (1005 Metric) package format. This surface mount device is rated at 0.063W (1/16W) power dissipation with moisture resistant construction and operates across the temperature range of -55°C to 155°C. The part is currently in active production status with ROHS3 compliance and unlimited moisture sensitivity level (MSL 1). Equivalent and substitute parts are identified when alternative manufacturers offer identical or functionally compatible 18 Ohm ±1% 0402 resistors meeting the same electrical specifications and package requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC1005F180CS is determined by strict equivalence across the following critical parameters: resistance value (18 Ohms), tolerance (±1%), package format (0402 / 1005 Metric), composition (thick film), temperature coefficient (±100ppm/°C), operating temperature range (-55°C ~ 155°C), and compliance certifications (ROHS3, REACH Unaffected, EAR99).

Substitute parts are categorized as follows:

Direct Equivalents: Parts meeting all electrical and mechanical specifications with identical power rating (0.063W / 1/16W) and packaging format.

Upgrade Category: Parts with enhanced power rating (0.1W / 1/10W) while maintaining all other specifications, suitable for applications requiring higher thermal margin.

Similar Category: Parts with additional certifications (AEC-Q200 automotive qualification) or enhanced features (moisture resistant construction) while maintaining core electrical specifications.

All substitute parts listed maintain the 0402 package footprint, 2-termination configuration, and operate within the specified temperature range.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts maintain active product status and ROHS3 compliance, ensuring regulatory alignment with the original RC1005F180CS specification.

Direct Equivalent Selection: CR0402-FX-18R0GLF (Bourns Inc.) and RC0402FR-0718RL (YAGEO) provide direct electrical and mechanical equivalence with identical 0.063W power rating and 0402 package format. RC0402FR-0718RL includes moisture resistant construction matching the original part's feature set.

Upgrade Path: ERJ-2RKF18R0X (Panasonic Electronic Components) offers increased power rating (0.1W) with automotive AEC-Q200 qualification, suitable for applications requiring enhanced thermal performance or automotive-grade reliability.

Automotive-Qualified Alternatives: AC0402FR-0718RL (YAGEO), CRCW040218R0FKED (Vishay Dale), and RMCF0402FT18R0 (Stackpole Electronics Inc) provide AEC-Q200 automotive qualification while maintaining the 0.063W power rating and 0402 package. AC0402FR-0718RL additionally includes moisture resistant construction.

All substitute parts operate within the -55°C to 155°C temperature range with ±100ppm/°C temperature coefficient and MSL 1 rating, ensuring compatibility with the original application requirements.

Frequently Asked Questions (FAQ)

Q: Can CR0402-FX-18R0GLF replace RC1005F180CS in all applications?

A: CR0402-FX-18R0GLF provides direct electrical equivalence with identical 18 Ohm resistance, ±1% tolerance, 0.063W power rating, and 0402 package format. Both parts operate across -55°C to 155°C with ±100ppm/°C temperature coefficient and MSL 1 rating. The primary difference is that CR0402-FX-18R0GLF does not specify moisture resistant construction, whereas RC1005F180CS includes this feature. Selection depends on application moisture exposure requirements.

Q: What is the difference between the 0.063W and 0.1W power-rated parts?

A: ERJ-2RKF18R0X is rated at 0.1W (1/10W) compared to the 0.063W (1/16W) rating of RC1005F180CS. Both maintain identical 18 Ohm resistance, ±1% tolerance, and 0402 package format. The higher power rating provides increased thermal margin and is suitable for applications with higher current or power dissipation requirements. The 0.1W part is a functional upgrade that maintains backward compatibility.

Q: Are AEC-Q200 qualified parts suitable for non-automotive applications?

A: AEC-Q200 automotive qualification indicates enhanced reliability testing and quality standards. Parts such as AC0402FR-0718RL, CRCW040218R0FKED, and RMCF0402FT18R0 meet automotive-grade specifications while maintaining all electrical parameters identical to the original RC1005F180CS. These parts are suitable for any application and provide additional quality assurance.

Q: Does package height variation affect PCB assembly compatibility?

A: AC0402FR-0718RL specifies maximum seated height of 0.015" (0.37mm), while RC1005F180CS and most other substitutes specify 0.016" (0.40mm). Both heights fall within standard 0402 package tolerances and are compatible with standard PCB assembly processes. Height variation does not affect electrical performance or footprint compatibility.

Q: What is the significance of MSL 1 rating?

A: MSL 1 (Moisture Sensitivity Level 1) indicates unlimited shelf life without moisture bake requirements. All listed substitute parts carry MSL 1 rating, meaning they do not require special moisture control during storage or handling, matching the original RC1005F180CS specification.

Q: Can I use RC0402FR-0718RL as a direct replacement for RC1005F180CS?

A: RC0402FR-0718RL provides direct equivalence with identical 18 Ohm resistance, ±1% tolerance, 0.063W power rating, 0402 package, and moisture resistant construction. Both parts operate across -55°C to 155°C with ±100ppm/°C temperature coefficient and MSL 1 rating. RC0402FR-0718RL is available in Cut Tape (CT) & Digi-Reel® packaging versus the original Tape & Reel (TR) format, which may affect procurement and assembly processes.
