Key Parameters

Substitute Part Grouping Explanation

Substitution for the ERJ-1TYJ243U is determined by the following critical parameters: resistance value (24 kOhms), tolerance (±5%), power rating (1W minimum), package type (2512), composition (thick film), and automotive qualification (AEC-Q200). Parts are grouped into three categories based on their relationship to the main part:

Direct Equivalents maintain identical electrical specifications and automotive ratings. These parts share the same resistance, tolerance, power rating, temperature coefficient, and operating temperature range as the ERJ-1TYJ243U.

Upgrade Options provide enhanced performance through higher power ratings, improved tolerance, or additional protective features while maintaining compatibility with the same package and resistance value.

Alternative Manufacturers offer functionally equivalent parts from different suppliers that meet the same electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Active Status Required): ERJ-S1TJ243U from Panasonic is the primary upgrade path, offering identical electrical specifications with Active product status and anti-sulfur protection. CRCW251224K0JNEG from Vishay Dale and RMCF2512JT24K0 from Stackpole Electronics provide functionally equivalent alternatives with Active status and full AEC-Q200 automotive qualification.

For Enhanced Performance: 352124KFT from TE Connectivity offers improved tolerance (±1% versus ±5%) and higher power rating (2W versus 1W) with lower temperature coefficient (±100ppm/°C versus ±200ppm/°C), suitable for applications requiring tighter tolerance control and greater thermal margin.

CRCW251224K0JNEGHP from Vishay Dale provides increased power handling (1.5W versus 1W) with pulse withstanding capability, appropriate for circuits subject to transient stress conditions.

Compliance Considerations: CRCW251224K0JNTG is not recommended for new designs due to RoHS non-compliance and REACH affected status, despite electrical equivalence.

352024KJT operates at reduced maximum temperature (-55°C to 125°C versus -55°C to 155°C) and lacks AEC-Q200 rating, limiting suitability for high-temperature automotive applications.

Frequently Asked Questions (FAQ)

Q: Can ERJ-S1TJ243U directly replace ERJ-1TYJ243U? A: Yes. ERJ-S1TJ243U maintains identical electrical specifications (24 kOhms ±5%, 1W, ±200ppm/°C, -55°C to 155°C) and package (2512), with the addition of anti-sulfur protection. Product status is Active, making it suitable for new designs.

Q: What is the difference between the main part and CRCW251224K0JNEG? A: Both parts are electrically and mechanically equivalent with identical resistance, tolerance, power rating, and operating temperature range. CRCW251224K0JNEG is manufactured by Vishay Dale and carries Active product status. Dimensional variations are minimal (0.248" L x 0.124" W versus 0.252" L x 0.126" W).

Q: When should 352124KFT be selected instead of direct equivalents? A: 352124KFT is appropriate when circuit design requires tighter tolerance control (±1% versus ±5%) or higher power dissipation capability (2W versus 1W). The lower temperature coefficient (±100ppm/°C) provides improved stability across the operating temperature range.

Q: Is CRCW251224K0JNEGHP compatible with the original design? A: CRCW251224K0JNEGHP is mechanically and electrically compatible, with the same resistance, tolerance, and operating temperature range. The increased power rating (1.5W) and pulse withstanding feature provide additional margin for transient conditions without affecting normal circuit operation.

Q: Why is 352024KJT not recommended as a primary substitute? A: 352024KJT lacks AEC-Q200 automotive qualification and operates at a reduced maximum temperature of 125°C compared to the 155°C rating of the ERJ-1TYJ243U. These limitations make it unsuitable for automotive applications requiring full temperature range operation.

Q: Are all substitute parts available in the same packaging format? A: Yes. All listed substitute parts are supplied in Tape & Reel (TR) packaging in the 2512 (6432 Metric) package format, ensuring compatibility with standard pick-and-place assembly equipment.

Q: What compliance certifications apply to the substitute parts? A: ROHS3 compliance is confirmed for ERJ-S1TJ243U, 352124KFT, CRCW251224K0JNEG, RMCF2512JT24K0, and CRCW251224K0JNEGHP. CRCW251224K0JNTG is RoHS non-compliant. All parts with AEC-Q200 rating are suitable for automotive applications.
