Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC1005F17R8CS is determined by strict equivalence across the following critical parameters: resistance value (17.8 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 grouped into two categories:

Direct Equivalent: Parts matching all electrical and mechanical specifications of the main part, including identical power rating (0.063W / 1/16W) and moisture-resistant thick film construction without automotive qualification.

Upgrade / Enhanced Specification: Parts that exceed the main part specifications in power rating (0.1W / 1/10W) or include additional automotive qualification (AEC-Q200), while maintaining all other critical parameters. These parts provide enhanced reliability margins and are suitable for applications requiring automotive-grade components.

All substitute parts maintain identical operating temperature range (-55°C ~ 155°C), temperature coefficient (±100ppm/°C), and compliance status (REACH Unaffected, EAR99). Selection between direct equivalents and automotive-qualified upgrades depends on application requirements and supply chain availability.

Frequently Asked Questions (FAQ)

Q: Can RC0402FR-0717R8L (YAGEO) be used as a direct replacement for RC1005F17R8CS (Samsung)?

A: Yes. RC0402FR-0717R8L is a direct equivalent substitute. Both parts share identical resistance (17.8 Ohms), tolerance (±1%), power rating (0.063W / 1/16W), 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). No circuit modifications are required.

Q: What is the difference between the main part and the Panasonic ERJ-2RKF17R8X?

A: The primary difference is power rating and automotive qualification. ERJ-2RKF17R8X has a higher power rating (0.1W / 1/10W vs. 0.063W / 1/16W) and includes AEC-Q200 automotive qualification. All other electrical and mechanical parameters are identical. The higher power rating provides increased thermal margin and is suitable for applications requiring automotive-grade components.

Q: Are the Vishay Dale CRCW040217R8FKED and Stackpole RMCF0402FT17R8 interchangeable with the main part?

A: Both parts are functionally interchangeable with the main part for standard applications. Both include AEC-Q200 automotive qualification, which is an enhancement over the main part. Resistance, tolerance, power rating, package format, and operating temperature range are identical. Selection depends on application requirements for automotive qualification and supply chain availability.

Q: Can I use the higher power rating Panasonic ERJ-2RKF17R8X in place of the 0.063W rated main part?

A: Yes. The Panasonic ERJ-2RKF17R8X with 0.1W power rating is a suitable upgrade substitute. Higher power rating components are backward compatible with applications designed for lower power ratings. The component will operate within specified parameters and provides additional thermal margin. All other electrical specifications remain identical.

Q: What does AEC-Q200 qualification mean?

A: AEC-Q200 is an automotive industry standard qualification for passive components. It certifies that the component meets automotive reliability and quality requirements. Components with AEC-Q200 qualification (Panasonic ERJ-2RKF17R8X, Vishay Dale CRCW040217R8FKED, Stackpole RMCF0402FT17R8) are suitable for automotive applications and applications requiring automotive-grade reliability standards.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts (RC0402FR-0717R8L, ERJ-2RKF17R8X, CRCW040217R8FKED, RMCF0402FT17R8) are RoHS3 compliant and REACH Unaffected, matching the compliance status of the main part RC1005F17R8CS.

Q: What is MSL 1 (Unlimited) rating?

A: MSL 1 (Moisture Sensitivity Level 1) with Unlimited rating indicates that the component has no moisture sensitivity restrictions. The component can be stored and handled without special moisture control measures. All listed parts share this MSL 1 rating.

Q: Can I mix different manufacturers' parts in the same circuit board assembly?

A: Yes. All substitute parts meet identical electrical and mechanical specifications for the 0402 package format. They can be used interchangeably in the same circuit board assembly. Mixing manufacturers is acceptable from an electrical and mechanical compatibility standpoint. Supply chain and inventory management considerations may influence manufacturer selection.
