Substitute Part Grouping Explanation

Substitution eligibility for the ERJ-S1TF2432U is determined by strict equivalence across the following critical parameters:

• Resistance value: 24.3 kOhms
• Tolerance: ±1%
• Power rating: 1W
• Package type: 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-1TNF2432U meets all electrical and mechanical substitution criteria. This part shares identical resistance, tolerance, power rating, package dimensions, temperature characteristics, and compliance certifications. The primary distinction is product status classification and the absence of anti-sulfur coating in the substitute part.

Parameter Comparison

Engineering Selection Recommendations

The ERJ-S1TF2432U is the preferred selection for new designs due to its active product status and anti-sulfur coating, which provides enhanced reliability in corrosive environments. The ERJ-1TNF2432U is classified as "Not For New Designs" and should be used only for legacy system maintenance, repair, or when supply of the primary part is unavailable.

Both parts maintain identical electrical performance, mechanical compatibility, and compliance certifications (AEC-Q200, ROHS3). The substitution is electrically and mechanically valid for applications where anti-sulfur protection is not a design requirement.

Frequently Asked Questions (FAQ)

Q: Can ERJ-1TNF2432U be used as a direct replacement for ERJ-S1TF2432U in new designs?

A: No. The ERJ-1TNF2432U carries "Not For New Designs" status. While electrically and mechanically equivalent, new designs must use the ERJ-S1TF2432U. The substitute part is suitable only for legacy system support or temporary supply solutions.

Q: What is the difference between anti-sulfur and standard thick film resistors?

A: Anti-sulfur coating provides protection against sulfur-containing contaminants in the environment. The ERJ-S1TF2432U includes this protective coating; the ERJ-1TNF2432U does not. Selection depends on application environment requirements.

Q: Are the package dimensions identical between these parts?

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). PCB layout and assembly processes are interchangeable.

Q: Do both parts meet automotive qualification standards?

A: Yes. Both the ERJ-S1TF2432U and ERJ-1TNF2432U are AEC-Q200 qualified and suitable for automotive applications within the specified operating temperature range of -55°C to 155°C.

Q: What is the moisture sensitivity level for these resistors?

A: Both parts have MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. Standard storage and handling procedures apply without special drying requirements.
