Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RC1005F334CS are classified based on strict electrical and mechanical parameter matching. All substitute candidates must satisfy the following core criteria:

Mandatory Matching Parameters:

• Resistance value: 330 kOhms
• Tolerance: ±1%
• Package format: 0402 (1005 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C to 155°C
• Terminations: 2
• RoHS compliance: ROHS3 Compliant
• Moisture sensitivity level: 1 (Unlimited)

Allowable Variation Parameters:

• Power rating: 0.063W (1/16W) or higher
• Packaging format: Tape & Reel (TR) or Cut Tape (CT) & Digi-Reel®
• Additional features: Moisture resistant, automotive AEC-Q200, anti-sulfur characteristics

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

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent Selection: CR0402-FX-3303GLF (Bourns Inc.) and RC0402FR-07330KL (YAGEO) function as direct electrical and mechanical equivalents to the RC1005F334CS. Both parts maintain identical resistance, tolerance, power rating, package dimensions, and temperature specifications. Selection between these options depends on packaging preference: CR0402-FX-3303GLF is supplied in Cut Tape & Digi-Reel® format, while RC0402FR-07330KL offers the same packaging option with added moisture resistant characteristics matching the original part.

Moisture Resistant Equivalent: RC0402FR-07330KL (YAGEO) is recommended when moisture resistant properties are required to match the original Samsung part specification. This part maintains all electrical parameters while providing the same environmental protection characteristics.

Automotive-Grade Alternatives: AC0402FR-07330KL, AF0402FR-07330KL (YAGEO), CRCW0402330KFKED (Vishay Dale), and RMCF0402FT330K (Stackpole Electronics Inc) are suitable substitutes when automotive AEC-Q200 qualification is required or preferred. These parts maintain identical electrical specifications with added automotive reliability certifications. AF0402FR-07330KL provides additional anti-sulfur protection. All automotive-grade options are Active products with ROHS3 compliance.

Upgraded Power Rating Option: ERJ-2RKF3303X (Panasonic Electronic Components) provides a higher power rating of 0.1W (1/10W) compared to the 0.063W (1/16W) specification of the original part. This upgrade is electrically compatible and suitable for applications requiring enhanced thermal performance while maintaining all other electrical and mechanical parameters.

Frequently Asked Questions (FAQ)

Q: Can CR0402-FX-3303GLF replace RC1005F334CS in all applications? A: CR0402-FX-3303GLF is electrically and mechanically equivalent to RC1005F334CS. Both parts share identical resistance (330 kOhms), tolerance (±1%), power rating (0.063W), package format (0402), temperature coefficient (±100ppm/°C), and operating temperature range (-55°C to 155°C). The primary difference is packaging format: CR0402-FX-3303GLF uses Cut Tape & Digi-Reel® while RC1005F334CS uses Tape & Reel. Substitution is valid when packaging compatibility with assembly equipment is confirmed.

Q: What is the difference between RC0402FR-07330KL and CR0402-FX-3303GLF? A: Both parts are direct electrical equivalents with identical specifications. RC0402FR-07330KL (YAGEO) includes moisture resistant characteristics, while CR0402-FX-3303GLF (Bourns Inc.) does not specify this feature. Selection depends on application requirements for moisture protection and manufacturer preference.

Q: Can automotive-grade parts like RMCF0402FT330K be used in non-automotive applications? A: Automotive AEC-Q200 qualified parts such as RMCF0402FT330K exceed the reliability and qualification requirements of standard industrial applications. These parts are fully compatible with non-automotive designs and provide enhanced reliability margins. Substitution is valid and offers no disadvantage.

Q: Is ERJ-2RKF3303X a suitable replacement for RC1005F334CS? A: ERJ-2RKF3303X is electrically compatible with RC1005F334CS. The key difference is power rating: ERJ-2RKF3303X is rated at 0.1W (1/10W) versus 0.063W (1/16W) for the original part. This higher power rating is a superset of the original specification and does not create compatibility issues. The part is suitable for direct substitution when higher thermal performance is acceptable.

Q: Are all substitute parts ROHS3 compliant? A: All substitute parts listed are ROHS3 compliant and maintain Moisture Sensitivity Level 1 (Unlimited), matching the environmental compliance profile of RC1005F334CS.

Q: What packaging formats are available among substitute parts? A: Substitute parts are supplied in two packaging formats: Tape & Reel (TR) and Cut Tape (CT) & Digi-Reel®. RC1005F334CS uses Tape & Reel format. Direct substitutes using identical packaging include AC0402FR-07330KL, AF0402FR-07330KL, and CRCW0402330KFKED. Parts using Cut Tape & Digi-Reel® format (CR0402-FX-3303GLF, RC0402FR-07330KL, ERJ-2RKF3303X, RMCF0402FT330K) require verification of assembly equipment compatibility.

Q: Can multiple substitute parts be used interchangeably in the same design? A: All substitute parts maintain identical electrical specifications (330 kOhms ±1%, ±100ppm/°C, -55°C to 155°C operating range). Interchangeability is confirmed for electrical function. Mechanical compatibility depends on packaging format and physical dimensions, which are standardized for 0402 package format across all listed parts.
