Substitute Part Grouping Explanation

Substitute parts for the RT0603FRE07348KL are qualified based on the following criteria:

• Identical resistance value: 348 kOhms
• Matching tolerance: ±1%
• Equivalent power rating: 0.1W (1/10W)
• Compatible package: 0603 (1608 Metric)
• Overlapping operating temperature range: -55°C to 155°C
• RoHS3 compliance maintained
• Unlimited moisture sensitivity rating (MSL 1)

The CRCW0603348KFKEA meets all electrical and mechanical substitution criteria. While composition differs (thick film versus thin film), both materials satisfy the specified tolerance, temperature range, and power requirements for this application category.

Parameter Comparison

Engineering Selection Recommendations

Both the RT0603FRE07348KL and CRCW0603348KFKEA maintain Active product status and full RoHS3 compliance. Selection between these parts depends on application-specific requirements:

The RT0603FRE07348KL thin film construction provides superior temperature coefficient performance (±50ppm/°C) suitable for precision analog circuits requiring minimal drift over temperature variations.

The CRCW0603348KFKEA thick film construction includes AEC-Q200 automotive qualification, making it appropriate for automotive and harsh environment applications where component reliability certification is mandated. The higher temperature coefficient (±100ppm/°C) remains within acceptable limits for general-purpose applications.

Both parts share identical electrical ratings, package dimensions, and compliance certifications, ensuring direct functional substitution within the specified operating parameters.

Frequently Asked Questions (FAQ)

Q: Can CRCW0603348KFKEA replace RT0603FRE07348KL in all applications?

A: Both parts meet the core electrical specifications (348 kOhms ±1%, 0.1W, -55°C to 155°C). The primary difference is temperature coefficient (±100ppm/°C versus ±50ppm/°C). Applications requiring precision analog performance with minimal temperature drift should retain the thin film RT0603FRE07348KL. General-purpose and automotive applications tolerate the CRCW0603348KFKEA thick film characteristics.

Q: Are the physical dimensions identical?

A: Both parts use the 0603 (1608 Metric) package. Minor dimensional variations exist: RT0603FRE07348KL measures 0.063" L × 0.031" W with 0.022" max height; CRCW0603348KFKEA measures 0.061" L × 0.033" W with 0.020" max height. These variations fall within standard PCB footprint tolerances and do not affect interchangeability.

Q: What is the significance of AEC-Q200 rating on the substitute part?

A: AEC-Q200 certification indicates the CRCW0603348KFKEA meets automotive industry reliability standards. This qualification is not present on the RT0603FRE07348KL. If automotive compliance is required, the CRCW0603348KFKEA is the appropriate selection.

Q: Do both parts have the same moisture sensitivity rating?

A: Yes. Both the RT0603FRE07348KL and CRCW0603348KFKEA carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions during storage or handling.

Q: What packaging formats are available?

A: The RT0603FRE07348KL is supplied in Tape & Reel (TR) format. The CRCW0603348KFKEA is available in Cut Tape (CT) and Digi-Reel® formats. Packaging selection depends on assembly process requirements and volume considerations.
