Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RC1005F6341CS are classified based on strict electrical and mechanical parameter matching. The primary substitution criteria are:

Core Matching Parameters:

• Resistance value: 6.34 kOhms
• Tolerance: ±1%
• Package / Case: 0402 (1005 Metric)
• Composition: Thick Film
• Temperature Coefficient: ±100 ppm/°C
• Operating Temperature Range: -55°C to 155°C
• Moisture Sensitivity Level: 1 (Unlimited)
• RoHS Status: ROHS3 Compliant

Substitution Categories:

Direct Equivalents maintain identical power ratings (0.063W / 1/16W) and all core electrical specifications. These parts are fully interchangeable without circuit redesign.

Upgrade Parts feature higher power ratings (0.1W / 1/10W) while maintaining all other electrical and mechanical specifications. These provide enhanced thermal performance and can be used in place of the original part.

Similar Parts include additional certifications such as Automotive AEC-Q200 qualification or enhanced moisture resistance features while maintaining core electrical parameters. These are suitable for applications requiring automotive-grade reliability.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement Applications: CR0402-FX-6341GLF (Bourns Inc.) and RC0402FR-076K34L (YAGEO) are direct equivalents to the RC1005F6341CS. Both maintain identical electrical specifications, power ratings, and package dimensions. Selection between these options depends on packaging preference (Tape & Reel versus Cut Tape & Digi-Reel) and supplier availability.

For Enhanced Thermal Performance: ERJ-2RKF6341X (Panasonic Electronic Components) provides a 0.1W power rating compared to the original 0.063W specification. This upgrade part maintains all other electrical and mechanical parameters, offering improved thermal margin in power-dissipation-sensitive applications while remaining compatible with existing PCB layouts.

For Automotive and Reliability-Critical Applications: AC0402FR-076K34L (YAGEO), CRCW04026K34FKED (Vishay Dale), and RMCF0402FT6K34 (Stackpole Electronics Inc) include Automotive AEC-Q200 certification. These parts are suitable for automotive-grade applications requiring enhanced reliability qualification. AC0402FR-076K34L additionally includes moisture resistant features matching the original part specification.

All substitute parts maintain ROHS3 compliance, unlimited moisture sensitivity level (MSL 1), and identical operating temperature ranges, ensuring regulatory and environmental compatibility with the original design.

Frequently Asked Questions (FAQ)

Q: Can CR0402-FX-6341GLF be used as a direct replacement for RC1005F6341CS?

A: Yes. CR0402-FX-6341GLF is a direct equivalent. Both parts share identical resistance (6.34 kOhms), tolerance (±1%), power rating (0.063W), package (0402), temperature coefficient (±100 ppm/°C), and operating temperature range (-55°C to 155°C). The primary difference is manufacturer and packaging format.

Q: What is the difference between the main part and ERJ-2RKF6341X?

A: ERJ-2RKF6341X is classified as an upgrade part. It maintains all electrical specifications and package dimensions identical to RC1005F6341CS but provides a higher power rating of 0.1W (1/10W) compared to 0.063W (1/16W). This upgrade allows for greater thermal headroom in applications with higher power dissipation requirements. ERJ-2RKF6341X also includes Automotive AEC-Q200 certification.

Q: Are the automotive-qualified parts (AC0402FR-076K34L, CRCW04026K34FKED, RMCF0402FT6K34) suitable for non-automotive applications?

A: Yes. Automotive AEC-Q200 certification represents an enhanced reliability qualification standard. Parts meeting this standard are fully compatible with non-automotive applications and provide equivalent or superior performance characteristics compared to non-automotive-qualified alternatives.

Q: Does packaging format affect electrical performance?

A: No. Packaging format (Tape & Reel versus Cut Tape & Digi-Reel) affects only handling, storage, and assembly processes. Electrical performance, resistance value, tolerance, power rating, and temperature characteristics remain identical regardless of packaging format.

Q: Can RC0402FR-076K34L replace RC1005F6341CS in moisture-sensitive applications?

A: Yes. RC0402FR-076K34L includes moisture resistant features and maintains MSL 1 (Unlimited) rating identical to RC1005F6341CS. Both parts are suitable for moisture-sensitive applications without additional protective measures.

Q: What is the significance of the ±100 ppm/°C temperature coefficient?

A: The temperature coefficient indicates resistance value change per degree Celsius within the operating temperature range. A ±100 ppm/°C specification means the resistance value will vary by a maximum of 0.01% per degree Celsius. This parameter is identical across all substitute parts, ensuring consistent temperature stability performance.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts maintain ROHS3 compliance identical to the main part RC1005F6341CS, ensuring regulatory compatibility for applications subject to RoHS directives.
