Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RC1005F184CS are classified based on strict electrical and mechanical parameter alignment. All identified substitutes maintain the following core specifications: 180 kOhms resistance value, ±1% tolerance, 0402 (1005 Metric) package format, thick film composition, ±100ppm/°C temperature coefficient, and -55°C to 155°C operating temperature range. Substitution eligibility is determined by equivalence in these parameters. Parts are further categorized by substitution type:

Direct Substitutes maintain identical electrical ratings (0.063W power), packaging format (Tape & Reel or Cut Tape), and moisture resistant or standard construction without additional certifications.

Upgrade Substitutes provide enhanced power rating (0.1W instead of 0.063W) or automotive qualification (AEC-Q200) while maintaining all other core parameters, enabling use in more demanding applications.

Similar Substitutes include automotive-qualified variants (AEC-Q200) or enhanced feature sets (anti-sulfur construction) with identical or equivalent electrical and mechanical specifications.

All substitutes are ROHS3 compliant, MSL 1 rated, and operate within the specified temperature range.

Parameter Comparison

Engineering Selection Recommendations

Direct Substitution (Identical Specifications)

CR0402-FX-1803GLF (Bourns Inc.) and RC0402FR-07180KL (YAGEO) are direct functional equivalents to the RC1005F184CS. Both maintain 0.063W power rating, 0402 package format, and ±1% tolerance with ±100ppm/°C temperature coefficient. RC0402FR-07180KL includes moisture resistant construction matching the original part. Both are ROHS3 compliant and MSL 1 rated. Selection between these options depends on packaging preference (Tape & Reel versus Cut Tape & Digi-Reel) and supplier availability.

Automotive-Qualified Substitutes

AC0402FR-07180KL, AF0402FR-07180KL, CRCW0402180KFKED, and RMCF0402FT180K incorporate AEC-Q200 automotive qualification while maintaining 0.063W power rating and 0402 package specifications. These parts are suitable for applications requiring automotive-grade reliability and environmental stress screening. AF0402FR-07180KL additionally includes anti-sulfur construction for enhanced corrosion resistance in harsh environments.

Enhanced Power Rating Substitute

ERJ-2RKF1803X (Panasonic Electronic Components) provides 0.1W power rating compared to the standard 0.063W, enabling use in applications with higher power dissipation requirements. This part maintains all other core specifications including 180 kOhms resistance, ±1% tolerance, 0402 package, and AEC-Q200 automotive qualification. Selection of this upgrade is appropriate when thermal margin or power handling capacity must be increased without changing circuit board layout.

Compliance and Certification

All identified substitutes are ROHS3 compliant, REACH unaffected, and classified as EAR99 for export control purposes. All parts carry MSL 1 (Unlimited) moisture sensitivity rating, indicating no special moisture handling requirements during storage or assembly.

Frequently Asked Questions (FAQ)

Q: Can CR0402-FX-1803GLF replace RC1005F184CS in all applications?

A: CR0402-FX-1803GLF is electrically and mechanically equivalent to RC1005F184CS with identical 180 kOhms resistance, ±1% tolerance, 0.063W power rating, and 0402 package format. The primary difference is packaging type (Tape & Reel for both). Direct substitution is valid for standard industrial applications. Verify with design documentation if moisture resistant construction is a specified requirement, as CR0402-FX-1803GLF does not list this feature.

Q: What is the difference between RC0402FR-07180KL and AC0402FR-07180KL?

A: Both parts are manufactured by YAGEO with identical 180 kOhms resistance, ±1% tolerance, and 0.063W power rating in 0402 package. RC0402FR-07180KL (RC_L series) provides moisture resistant construction without automotive qualification. AC0402FR-07180KL (AC series) includes both moisture resistant construction and AEC-Q200 automotive qualification. Selection depends on whether automotive-grade reliability certification is required for the application.

Q: Is ERJ-2RKF1803X a direct substitute or an upgrade?

A: ERJ-2RKF1803X is an upgrade substitute. It maintains the 180 kOhms resistance value, ±1% tolerance, 0402 package format, and temperature specifications of the RC1005F184CS, but increases power rating from 0.063W to 0.1W. This higher power rating provides additional thermal margin and is suitable for applications where the original 0.063W rating is marginal. The upgrade also includes AEC-Q200 automotive qualification. Circuit board layout remains compatible due to identical 0402 package dimensions.

Q: Are all substitute parts ROHS3 compliant?

A: All identified substitute parts are ROHS3 compliant and REACH unaffected. All carry MSL 1 (Unlimited) moisture sensitivity level, indicating compatibility with standard surface mount assembly processes without special moisture control requirements.

Q: What packaging options are available among the substitutes?

A: Substitute parts are available in two packaging formats: Tape & Reel (TR) and Cut Tape (CT) & Digi-Reel. CR0402-FX-1803GLF, ERJ-2RKF1803X, AF0402FR-07180KL, and CRCW0402180KFKED are supplied in Tape & Reel format. RC0402FR-07180KL and RMCF0402FT180K are supplied in Cut Tape & Digi-Reel format. Selection depends on assembly equipment compatibility and procurement volume requirements.

Q: Can AF0402FR-07180KL be used in corrosive environments?

A: AF0402FR-07180KL includes anti-sulfur construction in addition to moisture resistant properties and AEC-Q200 automotive qualification. This combination provides enhanced protection against sulfur-containing atmospheric contaminants and corrosive environments. The part maintains identical electrical specifications (180 kOhms, ±1%, 0.063W) and 0402 package format, making it suitable for applications exposed to industrial or marine environments where sulfur corrosion is a concern.

Q: What is the inventory status of substitute parts?

A: Inventory availability varies by part number. RC0402FR-07180KL (YAGEO) has 1560 units in stock. CR0402-FX-1803GLF (Bourns) has 995239 units available. ERJ-2RKF1803X (Panasonic) has 309810 units.
