Substitute Part Grouping Explanation

Substitution eligibility for the ERJ-S14F3652U is determined by strict equivalence across the following parameters:

• Resistance value: 36.5 kOhms
• Tolerance: ±1%
• Power rating: 0.5W
• Package format: 1210 (3225 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-14NF3652U qualifies as a direct substitute based on complete alignment with all electrical and mechanical parameters. Product status differences do not affect electrical compatibility.

Engineering Selection Recommendations

The ERJ-S14F3652U is the preferred selection for new designs due to its active production status. The ERJ-14NF3652U provides electrical and mechanical equivalence and is suitable for replacement applications, legacy system support, or when supply of the primary part is unavailable. Both parts carry identical AEC-Q200 automotive qualification and ROHS3 compliance certifications, ensuring regulatory and quality standard alignment.

Frequently Asked Questions (FAQ)

Q: Can ERJ-14NF3652U be used as a direct replacement for ERJ-S14F3652U in automotive applications?

A: Yes. Both parts meet AEC-Q200 automotive qualification standards and share identical electrical specifications (36.5 kOhms ±1%, 0.5W, ±100ppm/°C) and mechanical package format (1210). The difference in product status does not affect functional compatibility.

Q: What is the significance of the product status difference between these parts?

A: ERJ-S14F3652U is in active production, while ERJ-14NF3652U is marked "Not For New Designs." This designation indicates that ERJ-14NF3652U is in mature or declining production phase. For new product development, ERJ-S14F3652U is the recommended choice. ERJ-14NF3652U remains suitable for replacement, repair, and legacy system applications.

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

A: The ERJ-S14F3652U explicitly includes anti-sulfur protection in its specification. The ERJ-14NF3652U specification does not list this feature. This difference should be evaluated against application environmental requirements.

Q: Do both parts have identical moisture sensitivity ratings?

A: Yes. Both parts carry MSL 1 (Unlimited) moisture sensitivity level, indicating no moisture bake-out requirement prior to soldering.

Q: Can these parts be used interchangeably in PCB assembly?

A: Yes. Both parts use identical 1210 (3225 Metric) package format with 0.126" length, 0.098" width, and 0.028" maximum seated height. PCB footprints, pick-and-place programming, and reflow profiles are directly compatible.
