Parameter Comparison

Engineering Selection Recommendations

The ERJ-S14F6492U is the preferred selection for new designs due to its Active product status. This part maintains full manufacturer support and is optimized for current production requirements.

The ERJ-14NF6492U is classified as Not For New Designs but remains electrically and mechanically equivalent. This substitute is suitable for legacy system maintenance, field replacements, or applications where design revision is not feasible. The higher available inventory (10862 units) may provide supply chain advantages in specific procurement scenarios.

Both parts carry identical AEC-Q200 automotive qualification, ROHS3 compliance, and MSL 1 moisture sensitivity rating, ensuring compatibility in automotive and industrial applications operating across the -55°C to 155°C temperature range.

Frequently Asked Questions (FAQ)

Q: Can ERJ-14NF6492U be used as a direct replacement for ERJ-S14F6492U in existing designs?

A: Yes. Both parts are electrically and mechanically identical across all specified parameters including resistance, tolerance, power rating, package format, temperature coefficient, and operating temperature range. The difference in product status does not affect functional performance.

Q: What is the significance of the "Not For New Designs" status on the ERJ-14NF6492U?

A: This designation indicates that Panasonic recommends using the ERJ-S14F6492U for new product development. However, the ERJ-14NF6492U remains fully functional and qualified for use in existing applications or legacy system support.

Q: Are there any differences in the 1210 package dimensions between these parts?

A: No. Both parts use the identical 1210 (3225 Metric) package with dimensions of 0.126" L x 0.098" W (3.20mm x 2.50mm) and maximum seated height of 0.028" (0.70mm). They are footprint-compatible and require no PCB layout modifications.

Q: Do both parts meet automotive qualification requirements?

A: Yes. Both the ERJ-S14F6492U and ERJ-14NF6492U carry AEC-Q200 automotive qualification and are suitable for automotive applications requiring this certification level.

Q: What is the difference between the ERJ-S14 and ERJ-14N series designations?

A: The series designation reflects different product lines within Panasonic's resistor portfolio. The ERJ-S14 series represents the current active line, while the ERJ-14N series is a legacy line. Despite the series difference, the specific part numbers maintain full electrical and mechanical equivalence for the 64.9 kOhms ±1% 1210 package configuration.
