Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RC1005F18R2CS are classified based on strict electrical and mechanical parameter matching. The primary substitution criteria are:

Critical Parameters (Must Match):

• Resistance value: 18.2 Ohms
• Tolerance: ±1%
• Package / Case: 0402 (1005 Metric)
• Composition: Thick Film
• Temperature Coefficient: ±100ppm/°C
• Operating Temperature Range: -55°C to 155°C
• Number of Terminations: 2
• Physical dimensions: 1.00mm x 0.50mm

Secondary Parameters (Allowable Variation):

• Power Rating: 0.063W (1/16W) baseline; 0.1W (1/10W) represents an upgrade
• Features: Moisture Resistant designation; Automotive AEC-Q200 qualification
• Compliance: ROHS3 status; REACH status
• Packaging format: Cut Tape (CT) vs. Tape & Reel (TR)

Substitute parts are grouped into three categories:

Direct Substitutes: Parts with identical electrical specifications, power rating, and core features. These include CR0402-FX-18R2GLF (Bourns Inc.) and RC0402FR-0718R2L (YAGEO).

Upgrade Substitute: ERJ-2RKF18R2X (Panasonic Electronic Components) provides enhanced power rating (0.1W vs. 0.063W) while maintaining all other critical parameters and adding automotive AEC-Q200 qualification.

Similar Substitutes: Parts meeting all critical electrical and mechanical parameters but with additional features such as automotive AEC-Q200 qualification (AC0402FR-0718R2L, CRCW040218R2FKED, CRCW040218R2FKTD, RMCF0402FT18R2) or compliance variations.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Identical Specifications): CR0402-FX-18R2GLF (Bourns Inc.) and RC0402FR-0718R2L (YAGEO) are direct functional equivalents to RC1005F18R2CS. Both maintain identical electrical parameters, power rating, and temperature characteristics. Selection between these options depends on packaging format preference (Tape & Reel vs. Cut Tape) and supply chain availability. RC0402FR-0718L includes moisture resistant features matching the original part.

For Enhanced Power Dissipation: ERJ-2RKF18R2X (Panasonic Electronic Components) provides a 58% increase in power rating (0.1W vs. 0.063W) while maintaining all critical electrical parameters. This upgrade substitute is suitable for applications requiring higher thermal margin or increased power handling capability. The part includes automotive AEC-Q200 qualification and ROHS3 compliance.

For Automotive Applications: AC0402FR-0718R2L (YAGEO), CRCW040218R2FKED (Vishay Dale), RMCF0402FT18R2 (Stackpole Electronics Inc), and ERJ-2RKF18R2X (Panasonic Electronic Components) all carry AEC-Q200 automotive qualification. These parts are suitable for automotive-grade circuit designs. AC0402FR-0718R2L additionally includes moisture resistant features. All automotive-qualified options maintain ROHS3 compliance except CRCW040218R2FKTD.

Compliance Considerations: All substitute parts except CRCW040218R2FKTD maintain ROHS3 compliance. CRCW040218R2FKTD is RoHS non-compliant and REACH Affected, limiting its use in applications with strict environmental compliance requirements. For applications requiring ROHS3 compliance, select from CR0402-FX-18R2GLF, RC0402FR-0718R2L, ERJ-2RKF18R2X, AC0402FR-0718R2L, CRCW040218R2FKED, or RMCF0402FT18R2.

Frequently Asked Questions (FAQ)

Q: Can CR0402-FX-18R2GLF be used as a direct replacement for RC1005F18R2CS?

A: Yes. CR0402-FX-18R2GLF meets all critical electrical specifications: 18.2 Ohms ±1%, 0.063W power rating, 0402 package, ±100ppm/°C temperature coefficient, and -55°C to 155°C operating range. The primary difference is packaging format (Tape & Reel vs. Cut Tape) and the absence of explicit moisture resistant designation in the CR0402 series documentation.

Q: What is the difference between the main part and ERJ-2RKF18R2X?

A: ERJ-2RKF18R2X is an upgrade substitute with enhanced power rating (0.1W vs. 0.063W). All other electrical parameters remain identical. The upgrade provides 58% additional power dissipation capacity and includes automotive AEC-Q200 qualification. Physical dimensions and package remain 0402 (1005 Metric).

Q: Are all substitute parts suitable for automotive applications?

A: No. Only ERJ-2RKF18R2X, AC0402FR-0718R2L, CRCW040218R2FKED, CRCW040218R2FKTD, and RMCF0402FT18R2 carry AEC-Q200 automotive qualification. The original RC1005F18R2CS and direct substitutes CR0402-FX-18R2GLF and RC0402FR-0718R2L do not have automotive qualification.

Q: Which substitute parts maintain ROHS3 compliance?

A: CR0402-FX-18R2GLF, RC0402FR-0718R2L, ERJ-2RKF18R2X, AC0402FR-0718R2L, CRCW040218R2FKED, and RMCF0402FT18R2 are all ROHS3 compliant. CRCW040218R2FKTD is RoHS non-compliant and should not be used in applications with environmental compliance requirements.

Q: Does packaging format affect electrical performance?

A: No. Cut Tape (CT) and Tape & Reel (TR) packaging formats do not affect electrical performance or component specifications. Selection depends on assembly process requirements and supply chain logistics. Cut Tape is suitable for manual or small-batch assembly; Tape & Reel is standard for automated pick-and-place manufacturing.

Q: Can RC0402FR-0718R2L replace RC1005F18R2CS in moisture-sensitive applications?

A: Yes. RC0402FR-0718R2L includes moisture resistant features matching the original RC1005F18R2CS. Both components have MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions. The moisture resistant designation provides additional protection in high-humidity environments.

Q: What is the significance of the ±100ppm/°C temperature coefficient?

A: The ±100ppm/°C temperature coefficient indicates the maximum resistance change per degree Celsius across the operating temperature range. All listed substitute parts maintain this specification, ensuring consistent performance across -55°C to 155°C. This parameter is critical for precision analog circuits and temperature-compensated applications.

Q: Are there inventory considerations when selecting a substitute?

A: Yes. Inventory levels vary significantly: RC0402FR-0718R2L (YAGEO) has 188,840 pcs available, ERJ-2RKF18R2X (Panasonic) has 331,550 pcs, while CRCW040218R2FKTD (Vishay Dale) has only 11,097 pcs. High-volume production may benefit from parts with larger available inventory to ensure supply continuity.
