ERJ-S02F1242X Equivalent & Substitute Parts

Part Overview

The ERJ-S02F1242X is a 12.4 kOhms ±1% thick film chip resistor in 0402 (1005 Metric) package rated for 0.1W power dissipation. This component is manufactured by Panasonic Electronic Components and is designed for automotive applications with AEC-Q200 qualification and anti-sulfur protection. The part is currently active in production with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Substitute parts are identified when equivalent electrical and mechanical specifications are required due to inventory constraints, supply chain considerations, or design flexibility needs.

Substitute Part Grouping Explanation

Substitution eligibility for the ERJ-S02F1242X is determined by strict equivalence across the following critical parameters:

• Resistance value: 12.4 kOhms
• Tolerance: ±1%
• Power rating: 0.1W
• Package: 0402 (1005 Metric)
• Composition: Thick Film
• Temperature coefficient: ±200ppm/°C
• Operating temperature range: -55°C ~ 155°C
• Automotive qualification: AEC-Q200
• Anti-sulfur protection: Required
• RoHS compliance: ROHS3
• Moisture sensitivity: MSL 1

The ERJ-U02F1242X meets all these criteria and is classified as a direct substitute. Both parts are manufactured by Panasonic Electronic Components and share identical electrical performance and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

Both ERJ-S02F1242X and ERJ-U02F1242X are active production parts from Panasonic Electronic Components with identical compliance certifications. The ERJ-U02F1242X is a direct functional equivalent suitable for applications requiring the ERJ-S02F1242X. Selection between these parts may be based on availability, packaging format (Tape & Reel), or supply chain logistics, as both parts maintain ROHS3 compliance, AEC-Q200 automotive qualification, and unlimited moisture sensitivity rating. No electrical or mechanical performance differences exist between these components.

Frequently Asked Questions (FAQ)

Q: Can ERJ-U02F1242X replace ERJ-S02F1242X in automotive applications?

A: Yes. Both parts are AEC-Q200 qualified with identical resistance, tolerance, power rating, temperature coefficient, and operating temperature range. They are mechanically and electrically interchangeable.
