Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ERJ-S1TF3323U is determined by strict equivalence across the following critical parameters:

• Resistance value: 332 kOhms
• Tolerance: ±1%
• Power rating: 1W
• Package: 2512 (6432 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°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 electrical and mechanical specifications. Dimensional variations within supplier tolerances (length 0.248" to 0.252", width 0.124" to 0.126", height 0.028" maximum) are acceptable for PCB footprint compatibility in the 2512 package class.

Engineering Selection Recommendations

For new designs, select from parts with Active product status: ERJ-S1TF3323U (Panasonic), CRCW2512332KFKEG (Vishay Dale), or RMCF2512FT332K (Stackpole Electronics Inc). All three maintain full AEC-Q200 automotive qualification and ROHS3 compliance.

The ERJ-1TNF3323U carries a "Not For New Designs" status and should be reserved for legacy design support or existing production lines only, despite higher inventory availability.

All listed parts are functionally equivalent within the specified electrical and mechanical parameters. Selection may be based on supply availability, lead time, or established supplier relationships without compromising circuit performance or reliability requirements.

Frequently Asked Questions (FAQ)

Q: Can ERJ-1TNF3323U be used in new automotive designs? A: No. The ERJ-1TNF3323U is marked "Not For New Designs." Use ERJ-S1TF3323U, CRCW2512332KFKEG, or RMCF2512FT332K for new designs.

Q: Are dimensional differences between substitute parts significant? A: No. All parts use the 2512 (6432 Metric) package with maximum seated height of 0.028". Length and width variations (0.248" to 0.252" and 0.124" to 0.126" respectively) fall within standard PCB footprint tolerances and do not affect board assembly or performance.

Q: Do all substitute parts meet automotive requirements? A: Yes. All listed parts carry AEC-Q200 qualification and operate across the -55°C to 155°C temperature range, meeting automotive reliability standards.

Q: Is RoHS compliance consistent across all parts? A: Yes. All parts are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating.

Q: Which substitute offers the best availability? A: RMCF2512FT332K (Stackpole) has the highest inventory at 7019 units, followed by ERJ-1TNF3323U (Panasonic) at 5684 units and CRCW2512332KFKEG (Vishay Dale) at 5506 units.
