Equivalent & Substitute Parts for ERJ-S1TJ680U
Part Overview
The ERJ-S1TJ680U is a 68 Ohms ±5% 1W thick film chip resistor in 2512 (6432 Metric) package manufactured by Panasonic Electronic Components. This part features anti-sulfur coating and automotive AEC-Q200 qualification, designed for high-reliability applications in automotive and industrial environments. The product is currently active and available in high volume inventory.
Substitute parts are necessary when the primary part becomes unavailable, when design requirements shift to alternative manufacturers, or when supply chain optimization requires qualified alternatives that meet identical electrical and mechanical specifications.

Substitute Part Grouping Explanation
Substitution eligibility for the ERJ-S1TJ680U is determined by strict equivalence across the following parameters:
- Resistance value: 68 Ohms
- Tolerance: ±5%
- Power rating: 1W
- Package: 2512 (6432 Metric)
- Composition: Thick Film
- Temperature coefficient: ±200ppm/°C
- Operating temperature range: -55°C to 155°C minimum
- RoHS3 compliance
- MSL rating: 1 (Unlimited)
All listed substitute parts meet these core electrical and mechanical requirements. Variations in physical dimensions (length, width, height) within standard manufacturing tolerances do not affect functional substitutability. Automotive AEC-Q200 qualification is present on the main part and several substitutes but is not a mandatory substitution criterion for non-automotive applications.

Engineering Selection Recommendations
For new designs, select from parts with Active product status: ERJ-S1TJ680U (Panasonic), CR2512-JW-680ELF (Bourns), CRCW251268R0JNEG (Vishay Dale), or RMCF2512JT68R0 (Stackpole Electronics).
For automotive applications requiring AEC-Q200 qualification, use ERJ-S1TJ680U, CRCW251268R0JNEG, or RMCF2512JT68R0.
The ERJ-1TYJ680U is marked "Not For New Designs" and should be used only for legacy design maintenance or replacement in existing production.
The 352068RJT from TE Connectivity has a reduced upper operating temperature limit of 125°C compared to 155°C on other substitutes. This part is suitable only for applications with maximum operating temperature not exceeding 125°C.
All substitute parts are ROHS3 compliant with MSL rating 1 (Unlimited), ensuring compatibility with standard manufacturing and storage conditions.
Frequently Asked Questions (FAQ)
Q: Can ERJ-1TYJ680U replace ERJ-S1TJ680U in new designs?
A: No. ERJ-1TYJ680U is marked "Not For New Designs" and should be used only for legacy applications or existing production maintenance.
Q: Is 352068RJT a direct substitute for all applications?
A: 352068RJT is electrically equivalent but has a maximum operating temperature of 125°C versus 155°C on the main part. Use this substitute only when your application operates within -55°C to 125°C.
Q: Do all substitutes have automotive AEC-Q200 qualification?
A: No. ERJ-S1TJ680U, CRCW251268R0JNEG, and RMCF2512JT68R0 carry AEC-Q200 qualification. CR2512-JW-680ELF and 352068RJT do not. Select AEC-Q200 qualified parts for automotive applications.
Q: Are there physical dimension differences between substitutes?
A: Minor variations exist within standard manufacturing tolerances. All parts use the 2512 (6432 Metric) package and are PCB footprint compatible. Verify specific dimension requirements for your application if space constraints are critical.
Q: What is the significance of the anti-sulfur feature on ERJ-S1TJ680U?
A: The anti-sulfur coating on ERJ-S1TJ680U is a specific feature not listed on all substitutes. If your application requires this feature, confirm with the substitute manufacturer or retain the original part.
Q: Are all substitutes RoHS3 compliant?
A: Yes. All listed substitute parts are ROHS3 compliant with MSL rating 1 (Unlimited).
