ERJ-S14F2492U Equivalent & Substitute Parts

Part Overview

The ERJ-S14F2492U is a 24.9 kOhms ±1% thick film chip resistor manufactured by Panasonic Electronic Components in the 1210 (3225 Metric) package format. This component is rated for 0.5W power dissipation and is designed for automotive applications with AEC-Q200 qualification and anti-sulfur protection. The part is currently in active production status with 1,133 units available in inventory.

Substitute parts are necessary when the primary part becomes unavailable, when design requirements shift to alternative manufacturers, or when inventory constraints require sourcing from multiple suppliers while maintaining equivalent electrical and mechanical performance.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ERJ-S14F2492U is determined by strict equivalence across the following parameters: resistance value (24.9 kOhms), tolerance (±1%), power rating (0.5W), package format (1210), composition (thick film), temperature coefficient (±100ppm/°C), operating temperature range (-55°C to 155°C), and automotive qualification (AEC-Q200).

The identified substitute parts meet all these criteria and are therefore electrically and mechanically interchangeable. Substitutes are grouped by manufacturer and product status, with consideration given to inventory availability and design lifecycle status.

Parameter Comparison

Engineering Selection Recommendations

For new designs, the ERJ-S14F2492U (Panasonic, Active status) is the primary selection. The CRCW121024K9FKEA (Vishay Dale, Active status) serves as the preferred alternative when Panasonic inventory is constrained, offering identical electrical specifications with a slightly lower seated height (0.60mm vs. 0.70mm), which may provide marginal benefits in space-constrained applications.

The ERJ-14NF2492U (Panasonic, Not For New Designs status) is suitable only for legacy design support or replacement applications where existing designs already incorporate this part number. This part should not be selected for new product development.

All three parts carry AEC-Q200 automotive qualification and ROHS3 compliance, making them suitable for automotive and industrial applications requiring these certifications.

Frequently Asked Questions (FAQ)

Q: Can ERJ-14NF2492U be used as a direct replacement for ERJ-S14F2492U in new designs?

A: No. While ERJ-14NF2492U is electrically equivalent, its "Not For New Designs" status indicates it is in end-of-life phase. New designs should use ERJ-S14F2492U or CRCW121024K9FKEA.

Q: What is the significance of the height difference between ERJ-S14F2492U (0.70mm) and CRCW121024K9FKEA (0.60mm)?

A: Both parts meet the 1210 package specification. The 0.10mm height difference is within normal manufacturing tolerance and does not affect electrical performance. Height becomes relevant only in applications with strict PCB clearance constraints.

Q: Are all three parts suitable for automotive applications?

A: Yes. All three parts carry AEC-Q200 qualification and are rated for the -55°C to 155°C operating temperature range required for automotive use.

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

A: Both are Panasonic thick film chip resistors in the 1210 package. The ERJ-S14 series includes anti-sulfur protection and represents the current product line. The ERJ-14N series is the legacy line and is not recommended for new designs.

Q: Can these parts be used interchangeably on the same PCB assembly?

A: Yes. All three parts are mechanically and electrically equivalent within the specified parameters. PCB footprints and solder reflow profiles remain identical across all three part numbers.
