Substitute Part Grouping Explanation

Substitution eligibility for the ERJ-S1TF1303U is determined by strict equivalence across the following critical parameters:

• Resistance value: 130 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

The ERJ-1TNF1303U qualifies as a direct substitute based on full parameter alignment across all electrical and mechanical specifications. This part belongs to the ERJ-1TN series and maintains identical performance characteristics to the main part, with the distinction that it carries a "Not For New Designs" product status designation.

Engineering Selection Recommendations

The ERJ-S1TF1303U is the preferred selection for new designs due to its active product status. The ERJ-1TNF1303U provides electrical and mechanical equivalence and is suitable for legacy system support, field replacements, or applications where existing inventory must be utilized. Both parts meet identical AEC-Q200 automotive qualification requirements and ROHS3 compliance standards. Selection between these parts should be based on design phase requirements and supply chain availability rather than performance differentiation.

Frequently Asked Questions (FAQ)

Q: Can ERJ-1TNF1303U be used as a direct replacement for ERJ-S1TF1303U in new designs?

A: Electrically and mechanically, yes. However, the ERJ-1TNF1303U carries a "Not For New Designs" status. For new product development, the ERJ-S1TF1303U is the recommended choice. The ERJ-1TNF1303U is appropriate for legacy system maintenance or field replacements where supply constraints exist.

Q: Are there differences in anti-sulfur coating between these parts?

A: The ERJ-S1TF1303U explicitly includes anti-sulfur coating in its feature set. The ERJ-1TNF1303U does not list this feature. This distinction may be relevant for applications in high-sulfur environments.

Q: Do both parts have identical package dimensions?

A: Yes. Both parts use the 2512 (6432 Metric) package with identical dimensions: 0.252" L x 0.126" W (6.40mm x 3.20mm) and maximum seated height of 0.028" (0.70mm).

Q: What is the significance of the product status difference?

A: "Active" status indicates the ERJ-S1TF1303U is in current production and recommended for new designs. "Not For New Designs" status for the ERJ-1TNF1303U indicates it is in mature phase with limited production support, suitable only for existing applications or replacements.

Q: Are both parts suitable for automotive applications?

A: Yes. Both parts carry AEC-Q200 automotive qualification and operate across the -55°C ~ 155°C temperature range required for automotive environments.
