Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RC1005F1742CS are classified based on strict electrical and mechanical parameter alignment. The primary substitution criteria are:

Critical Parameters (Must Match):

• Resistance value: 17.4 kOhms
• Tolerance: ±1%
• Package: 0402 (1005 Metric)
• Composition: Thick Film
• Temperature Coefficient: ±100ppm/°C
• Operating Temperature Range: -55°C to 155°C
• Terminations: 2
• RoHS3 Compliance
• MSL 1 (Unlimited)

Allowable Variations:

• Power rating: 0.063W (1/16W) baseline; 0.1W (1/10W) represents an upgrade
• Features: Moisture resistant designation; automotive AEC-Q200 qualification
• Seated height: Minor dimensional tolerance within 0.015" to 0.016"

Substitute parts are grouped into three categories: Direct equivalents (identical electrical and mechanical specifications), upgrades (enhanced power rating), and similar alternatives (additional certifications or features).

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent Selection: CR0402-FX-1742GLF (Bourns Inc.) and RC0402FR-0717K4L (YAGEO) are direct electrical and mechanical equivalents to the RC1005F1742CS. Both maintain identical resistance, tolerance, power rating, package dimensions, and temperature specifications. RC0402FR-0717K4L includes moisture resistant designation matching the original part. Both are ROHS3 compliant with MSL 1 rating and active production status.

Moisture Resistant Preference: RC0402FR-0717K4L (YAGEO) and AC0402FR-0717K4L (YAGEO) both feature moisture resistant composition. AC0402FR-0717K4L additionally carries automotive AEC-Q200 qualification, providing enhanced reliability for automotive and harsh environment applications while maintaining identical electrical specifications to the original part.

Upgraded Power Rating: ERJ-2RKF1742X (Panasonic Electronic Components) provides a power rating upgrade from 0.063W to 0.1W while maintaining all other electrical parameters. This part is qualified to automotive AEC-Q200 standard and is suitable for applications requiring higher thermal margin or increased power dissipation capability.

Automotive Qualified Alternatives: AC0402FR-0717K4L (YAGEO), CRCW040217K4FKED (Vishay Dale), and RMCF0402FT17K4 (Stackpole Electronics Inc) all carry AEC-Q200 automotive qualification. These parts are suitable for automotive and mission-critical applications requiring enhanced reliability documentation and qualification testing.

Frequently Asked Questions (FAQ)

Q: Can CR0402-FX-1742GLF replace RC1005F1742CS in all applications? A: CR0402-FX-1742GLF is a direct electrical and mechanical equivalent. Both parts share identical resistance (17.4 kOhms), tolerance (±1%), power rating (0.063W), package (0402), temperature coefficient (±100ppm/°C), and operating range (-55°C to 155°C). The primary difference is the absence of explicit moisture resistant designation in the Bourns part. For moisture-sensitive applications, RC0402FR-0717K4L is recommended.

Q: What is the difference between the 0.063W and 0.1W power ratings? A: The 0.063W (1/16W) rating is the baseline specification for RC1005F1742CS. ERJ-2RKF1742X provides a 0.1W (1/10W) upgrade, offering approximately 58% higher power dissipation capability. This upgrade does not change electrical performance but provides greater thermal margin in high-power applications. The 0402 package dimensions remain identical.

Q: Are automotive AEC-Q200 qualified parts suitable for non-automotive applications? A: Yes. AEC-Q200 qualification indicates enhanced reliability testing and documentation. Parts such as AC0402FR-0717K4L, CRCW040217K4FKED, and RMCF0402FT17K4 meet or exceed commercial specifications and are suitable for any application requiring the specified electrical parameters. Automotive qualification does not restrict use in non-automotive circuits.

Q: What does MSL 1 (Unlimited) mean for moisture sensitivity? A: MSL 1 indicates the lowest moisture sensitivity level. Parts with this rating have unlimited shelf life and do not require special moisture control during storage or handling. All listed substitute parts carry MSL 1 rating, ensuring consistent moisture handling requirements across all alternatives.

Q: Can I use RC0402FR-0717K4L as a direct replacement for RC1005F1742CS? A: Yes. RC0402FR-0717K4L is manufactured by YAGEO and shares identical electrical specifications (17.4 kOhms ±1%, 0.063W, ±100ppm/°C, -55°C to 155°C) and package format (0402). Both include moisture resistant designation. This part is listed as a direct substitute and is suitable for drop-in replacement.

Q: What is the significance of the 0402 (1005 Metric) package designation? A: The 0402 package is a surface mount chip resistor measuring 1.00mm length × 0.50mm width. The metric designation (1005) refers to these dimensions in hundredths of a millimeter. All listed substitute parts use identical 0402 packaging, ensuring compatibility with existing PCB layouts and assembly equipment.

Q: Are there inventory considerations when selecting substitute parts? A: Inventory levels vary by manufacturer and distributor. RC0402FR-0717K4L (YAGEO) shows 147,594 units in stock, while CR0402-FX-1742GLF (Bourns) shows 27,074 units. ERJ-2RKF1742X (Panasonic) has 116,659 units available. Inventory status should be verified with current suppliers for procurement planning.
