Key Parameters

Substitute Part Grouping Explanation

Substitution of the RC6432F3480CS is determined by the following critical parameters that must match or remain within acceptable tolerances:

Electrical Parameters (Must Match):

• Resistance value: 348 Ohms
• Tolerance: ±1%
• Power rating: 1W
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C

Mechanical Parameters (Must Match):

• Package type: 2512 (6432 Metric)
• Physical dimensions within specified tolerances
• Number of terminations: 2

Compliance Parameters (Must Match or Exceed):

• RoHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)
• REACH Unaffected status

All identified substitute parts meet these criteria. Additional certifications such as AEC-Q200 automotive qualification present in some substitutes do not prevent substitution but indicate enhanced qualification levels.

Engineering Selection Recommendations

Primary Substitutes (Active Product Status):

AC2512FK-07348RL (YAGEO) and CRCW2512348RFKEG (Vishay Dale) are recommended as primary substitutes. Both components maintain Active product status, ensuring long-term availability and manufacturer support. Both include AEC-Q200 automotive qualification, providing additional reliability assurance beyond the base specification. These parts are available in Tape & Reel packaging suitable for automated assembly processes.

Secondary Substitute (Legacy Status):

ERJ-1TNF3480U (Panasonic Electronic Components) is classified as Not For New Designs. While electrically and mechanically equivalent, this part should be used only for replacement or repair of existing assemblies where design continuity is required. New circuit designs should utilize AC2512FK-07348RL or CRCW2512348RFKEG.

Compliance Verification:

All substitute parts maintain ROHS3 compliance and MSL Level 1 rating, ensuring compatibility with modern manufacturing processes and storage requirements. REACH Unaffected status is consistent across all parts.

Frequently Asked Questions (FAQ)

Q: Can AC2512FK-07348RL replace RC6432F3480CS directly in existing designs?

A: Yes. AC2512FK-07348RL matches all critical electrical parameters (348 Ohms, ±1%, 1W, ±100ppm/°C, -55°C ~ 155°C) and mechanical specifications (2512 package). The component is pin-compatible and functionally equivalent. AEC-Q200 certification provides enhanced qualification.

Q: What is the difference between the Samsung RC6432F3480CS and YAGEO AC2512FK-07348RL?

A: Both components are electrically and mechanically identical in critical specifications. The primary differences are manufacturer, packaging format (bulk vs. Tape & Reel), and additional AEC-Q200 automotive certification on the YAGEO part. Both are Active status products.

Q: Why is ERJ-1TNF3480U marked as Not For New Designs?

A: ERJ-1TNF3480U is classified as Not For New Designs by Panasonic, indicating the manufacturer is transitioning this product line. While the component remains electrically and mechanically equivalent, new circuit designs should specify AC2512FK-07348RL or CRCW2512348RFKEG to ensure long-term availability and manufacturer support.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. RC6432F3480CS, AC2512FK-07348RL, CRCW2512348RFKEG, and ERJ-1TNF3480U are all ROHS3 Compliant with MSL Level 1 rating, meeting current environmental and manufacturing standards.

Q: What packaging formats are available for these 348 Ohm 1W resistors?

A: RC6432F3480CS is supplied in bulk packaging. AC2512FK-07348RL, CRCW2512348RFKEG, and ERJ-1TNF3480U are supplied in Tape & Reel (TR) format suitable for automated pick-and-place assembly. Packaging selection depends on production volume and assembly process requirements.

Q: Can these parts be used interchangeably in high-temperature applications?

A: Yes. All parts share identical operating temperature range (-55°C ~ 155°C) and temperature coefficient (±100ppm/°C), ensuring equivalent performance in temperature-sensitive applications within this range.
