Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC1005F1873CS is determined by strict equivalence across the following critical parameters: resistance value (187 kOhms), 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 maintain identical electrical and mechanical specifications including power rating (0.063W / 1/16W), moisture resistance features, and dimensional constraints. These parts are interchangeable without circuit redesign.

Upgrade Substitutes provide enhanced power rating (0.1W / 1/10W) or additional certifications (AEC-Q200 automotive qualification) while maintaining all other core parameters. These parts support higher thermal stress applications and automotive environments.

Similar Substitutes match all electrical and mechanical specifications with variations in feature sets such as automotive AEC-Q200 qualification or enhanced moisture resistance. These parts are suitable for applications requiring specific environmental or quality certifications.

Parameter Comparison

Engineering Selection Recommendations

Direct Substitution (No Circuit Modification Required):

CR0402-FX-1873GLF (Bourns Inc.), RC0402FR-07187KL (YAGEO), and RMCF0402FT187K (Stackpole Electronics Inc) are electrically and mechanically equivalent to RC1005F1873CS. All maintain 187 kOhms resistance, ±1% tolerance, 0.063W power rating, 0402 package format, and -55°C to 155°C operating range. All parts are ROHS3 compliant and REACH unaffected. Selection among these direct equivalents is based on inventory availability and supply chain preference.

Upgrade Substitution (Enhanced Specifications):

ERJ-2RKF1873X (Panasonic Electronic Components) provides increased power rating of 0.1W (1/10W) compared to the 0.063W rating of RC1005F1873CS while maintaining all other electrical parameters. This upgrade is suitable for applications requiring higher thermal dissipation capability. The part includes AEC-Q200 automotive qualification and is ROHS3 compliant.

Automotive-Qualified Substitution:

AC0402FR-07187KL (YAGEO), CRCW0402187KFKED (Vishay Dale), and RMCF0402FT187K (Stackpole Electronics Inc) incorporate AEC-Q200 automotive qualification in addition to matching all core electrical and mechanical specifications of RC1005F1873CS. AC0402FR-07187KL additionally includes moisture resistant construction. These parts are appropriate for automotive and high-reliability applications requiring AEC-Q200 certification.

All substitute parts maintain ROHS3 compliance, REACH unaffected status, and EAR99 export classification consistent with the main part.

Frequently Asked Questions (FAQ)

Q: Can CR0402-FX-1873GLF replace RC1005F1873CS in existing designs without modification?

A: Yes. CR0402-FX-1873GLF is a direct equivalent with identical resistance (187 kOhms), tolerance (±1%), power rating (0.063W), package format (0402), temperature coefficient (±100ppm/°C), and operating temperature range (-55°C ~ 155°C). No circuit redesign is required.

Q: What is the difference between RC1005F1873CS and ERJ-2RKF1873X?

A: The primary difference is power rating. ERJ-2RKF1873X is rated at 0.1W (1/10W) compared to RC1005F1873CS at 0.063W (1/16W). ERJ-2RKF1873X includes AEC-Q200 automotive qualification. All other electrical parameters are identical. ERJ-2RKF1873X is suitable for applications requiring higher power dissipation or automotive certification.
