Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ERJ-S1TJ184U is determined by strict equivalence across the following critical parameters:

• Resistance value: 180 kOhms
• Tolerance: ±5%
• Power rating: 1W
• Package type: 2512 (6432 Metric)
• Composition: Thick Film
• Temperature coefficient: ±200ppm/°C
• Operating temperature range: -55°C ~ 155°C
• Automotive qualification: AEC-Q200
• RoHS compliance: ROHS3 Compliant
• Moisture sensitivity: MSL 1

All substitute parts listed below meet these criteria without exception. Physical dimensions remain within acceptable tolerances for PCB footprint compatibility.

Engineering Selection Recommendations

For new designs, select from parts with Active product status: ERJ-S1TJ184U (Panasonic), CRCW2512180KJNEG (Vishay Dale), or RMCF2512JT180K (Stackpole Electronics Inc). All three maintain full AEC-Q200 automotive qualification and ROHS3 compliance.

The ERJ-1TYJ184U carries a "Not For New Designs" status and should be reserved for legacy design maintenance or replacement applications only, despite higher inventory availability.

All substitute parts are functionally and mechanically interchangeable within the specified electrical and environmental parameters. Selection may be based on supplier availability, lead time, or procurement cost without compromising circuit performance or reliability.

Frequently Asked Questions (FAQ)

Q: Can ERJ-1TYJ184U be used in new automotive designs? A: No. ERJ-1TYJ184U is marked "Not For New Designs." Use ERJ-S1TJ184U, CRCW2512180KJNEG, or RMCF2512JT180K for new designs.

Q: Are physical dimensions identical across all substitute parts? A: Dimensions are within acceptable tolerance. ERJ-S1TJ184U and RMCF2512JT180K measure 0.252" L × 0.126" W. CRCW2512180KJNEG measures 0.248" L × 0.124" W. Both configurations fit standard 2512 PCB footprints.

Q: Do all parts meet automotive qualification requirements? A: Yes. All listed parts carry AEC-Q200 rating and operate across -55°C to 155°C.

Q: What is the significance of the anti-sulfur feature on ERJ-S1TJ184U? A: Anti-sulfur coating is a material property of the ERJ-S1TJ184U. Substitute parts do not explicitly list this feature but maintain equivalent performance in automotive environments.

Q: Are these parts RoHS compliant? A: Yes. All parts are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating.

Q: Can I mix different manufacturers in the same production batch? A: Yes. All parts meet identical electrical and environmental specifications. Mixed sourcing is permissible from a technical standpoint.
