Substitute Part Grouping Explanation

Substitution eligibility for the ERJ-S14F6813U is determined by strict equivalence across the following parameters:

• Resistance value: 681 kOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Power rating: 0.5W / 1/2W (exact match required)
• Package format: 1210 (3225 Metric) (exact match required)
• Composition: Thick Film (exact match required)
• Temperature coefficient: ±100ppm/°C (exact match required)
• Operating temperature range: -55°C ~ 155°C (exact match required)
• Automotive qualification: AEC-Q200 (exact match required)
• RoHS compliance: ROHS3 Compliant (exact match required)

Parts meeting all these criteria are electrically and mechanically interchangeable in applications designed for the ERJ-S14F6813U.

Parameter Comparison

Engineering Selection Recommendations

The ERJ-S14F6813U is the primary specification for new designs. Both substitute parts meet all electrical and mechanical equivalence criteria.

ERJ-14NF6813U is a Panasonic product designated as "Not For New Designs," indicating this series is in transition. This part remains electrically equivalent but should be avoided in new product development unless existing inventory constraints require its use.

CRCW1210681KFKEA is manufactured by Vishay Dale and carries active product status. This part is suitable for new designs and provides cross-manufacturer equivalence. The seated height specification is 0.024" (0.60mm) compared to 0.028" (0.70mm) for the Panasonic variants; this minor dimensional difference does not affect electrical performance or standard PCB assembly processes.

All three parts are AEC-Q200 qualified, ROHS3 compliant, and suitable for automotive applications within the specified temperature range.

Frequently Asked Questions (FAQ)

Q: Can ERJ-14NF6813U be used as a direct replacement for ERJ-S14F6813U?

A: Yes, ERJ-14NF6813U is electrically and mechanically equivalent. However, it is designated "Not For New Designs," indicating Panasonic is transitioning this series. Use only when existing inventory is available or supply constraints require substitution.

Q: Is CRCW1210681KFKEA compatible with designs specified for ERJ-S14F6813U?

A: Yes, CRCW1210681KFKEA meets all electrical and mechanical equivalence criteria. The seated height is 0.024" versus 0.028" for the Panasonic parts; this difference does not impact standard PCB assembly or electrical performance.

Q: What determines if a part can substitute for ERJ-S14F6813U?

A: Substitution requires exact matching of resistance value (681 kOhms), tolerance (±1%), power rating (0.5W), package format (1210), composition (Thick Film), temperature coefficient (±100ppm/°C), operating temperature range (-55°C ~ 155°C), AEC-Q200 qualification, and RoHS3 compliance.

Q: Are all substitute parts suitable for automotive applications?

A: Yes, all listed substitute parts carry AEC-Q200 automotive qualification and are suitable for automotive applications within the specified operating temperature range of -55°C to 155°C.

Q: What is the significance of the height difference between CRCW1210681KFKEA and the Panasonic variants?

A: The CRCW1210681KFKEA has a maximum seated height of 0.024" compared to 0.028" for ERJ-S14F6813U and ERJ-14NF6813U. This 0.004" difference is within standard PCB assembly tolerances and does not affect electrical performance or mechanical fit in standard 1210 package footprints.
