Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC1005F3402CS is determined by strict equivalence across the following critical parameters: resistance value (34 kOhms), tolerance (±1%), package format (0402 / 1005 Metric), composition (thick film), temperature coefficient (±100ppm/°C), operating temperature range (-55°C to 155°C), and compliance certifications (ROHS3, REACH Unaffected, EAR99).

Parts are grouped into three categories based on substitution relationship:

Direct Equivalents maintain identical electrical specifications and power rating (0.063W / 1/16W), identical packaging, and identical feature sets. These parts are pin-for-pin compatible with no design modifications required.

Upgrade Substitutes maintain all critical electrical parameters but feature enhanced power rating (0.1W / 1/10W) or additional certifications (Automotive AEC-Q200). These parts are electrically and mechanically compatible and provide superior performance margins.

Similar Substitutes maintain all critical electrical parameters and package specifications but may include additional certifications or feature enhancements. These parts are fully compatible and suitable for direct replacement.

All substitute parts listed maintain ROHS3 compliance, MSL 1 rating, and the specified operating temperature range.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent Selection: CR0402-FX-3402GLF (Bourns Inc.) and RC0402FR-0734KL (YAGEO) are direct functional equivalents to the RC1005F3402CS. Both maintain identical electrical specifications, power rating, package format, and ROHS3 compliance. CR0402-FX-3402GLF is suitable for general industrial applications. RC0402FR-0734KL includes moisture resistant construction matching the original part specification.

Upgrade Selection: ERJ-2RKF3402X (Panasonic Electronic Components) provides enhanced power rating at 0.1W (1/10W) with Automotive AEC-Q200 certification. This part is suitable for applications requiring automotive-grade reliability or where additional thermal margin is beneficial. All electrical parameters remain equivalent to the primary part.

Automotive-Grade Alternatives: AC0402FR-0734KL (YAGEO), CRCW040234K0FKED (Vishay Dale), and RMCF0402FT34K0 (Stackpole Electronics Inc) all feature Automotive AEC-Q200 certification while maintaining the 0.063W power rating and moisture resistant or equivalent construction. These parts are appropriate for automotive applications or designs requiring automotive-grade component qualification.

All substitute parts maintain ROHS3 compliance, MSL 1 rating, and the full operating temperature range of -55°C to 155°C. Selection should be based on application requirements, packaging preference (Tape & Reel vs. Cut Tape), and any automotive or environmental certifications mandated by the end application.

Frequently Asked Questions (FAQ)

Q: Can CR0402-FX-3402GLF be used as a direct replacement for RC1005F3402CS?

A: Yes. CR0402-FX-3402GLF is a direct equivalent. Both parts share identical resistance (34 kOhms), tolerance (±1%), power rating (0.063W), package format (0402), composition (thick film), temperature coefficient (±100ppm/°C), and operating temperature range (-55°C to 155°C). No circuit modifications are required.

Q: What is the difference between the 0.063W and 0.1W power ratings?

A: The RC1005F3402CS is rated at 0.063W (1/16W), while ERJ-2RKF3402X is rated at 0.1W (1/10W). The higher power rating in ERJ-2RKF3402X provides greater thermal margin and allows operation at higher power dissipation levels. Both parts are electrically equivalent and mechanically compatible. The 0.1W part is suitable for applications where additional thermal headroom is required.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All substitute parts listed (CR0402-FX-3402GLF, RC0402FR-0734KL, ERJ-2RKF3402X, AC0402FR-0734KL, CRCW040234K0FKED, and RMCF0402FT34K0) are ROHS3 compliant and REACH unaffected, matching the compliance status of the primary part RC1005F3402CS.

Q: What does Automotive AEC-Q200 certification mean?

A: AEC-Q200 is an automotive electronics council qualification standard for passive components. Parts bearing this certification (ERJ-2RKF3402X, AC0402FR-0734KL, CRCW040234K0FKED, RMCF0402FT34K0) have undergone additional reliability testing and are qualified for automotive applications. These parts are suitable for use in non-automotive applications as well.

Q: Does RC0402FR-0734KL include moisture resistant construction?

A: Yes. RC0402FR-0734KL includes moisture resistant thick film construction, matching the moisture resistant feature of the primary part RC1005F3402CS. Both parts maintain MSL 1 (unlimited) moisture sensitivity level.

Q: What is the difference between Tape & Reel and Cut Tape packaging?

A: Tape & Reel (TR) packaging is supplied on continuous carrier tape wound on reels, suitable for automated pick-and-place assembly. Cut Tape (CT) packaging is supplied as individual segments cut from the carrier tape, suitable for manual assembly or smaller production runs. RC0402FR-0734KL is supplied in Cut Tape & Digi-Reel format; all other parts are supplied in Tape & Reel format. Electrical and mechanical specifications are identical regardless of packaging format.

Q: Can I use AC0402FR-0734KL in a non-automotive application?

A: Yes. AC0402FR-0734KL is fully compatible with non-automotive applications. The Automotive AEC-Q200 certification indicates the part meets automotive reliability standards but does not restrict its use to automotive applications. This part is suitable for any application requiring a 34 kOhm ±1% 0402 resistor.

Q: Are all substitute parts available in the same package size?

A: Yes. All substitute parts are manufactured in the 0402 (1005 Metric) package format with identical dimensions: 0.039" L x 0.020" W (1.00mm x 0.50mm). Maximum seated height ranges from 0.015" to 0.016" (0.37mm to 0.40mm), which is within standard PCB assembly tolerances and does not affect interchangeability.
