Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ERJ-S14F3482U is determined by strict equivalence across the following parameters:

• Resistance value: 34.8 kOhms
• Tolerance: ±1%
• Power rating: 0.5W (1/2W)
• 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

All identified substitute parts meet these criteria. Variations in product status (Active vs. Not For New Designs) and physical height do not affect electrical or mechanical interchangeability within the specified package envelope.

Parameter Comparison

Engineering Selection Recommendations

For new design implementations, the ERJ-S14F3482U (Panasonic, Active status) and CRCW121034K8FKEA (Vishay Dale, Active status) are both suitable selections. Both components carry active product status and meet current manufacturing standards.

The ERJ-14NF3482U carries a "Not For New Designs" status and should be used only for legacy system maintenance or replacement applications where design continuity is required.

All three parts satisfy AEC-Q200 automotive qualification requirements and ROHS3 compliance mandates. Selection between active-status alternatives may be based on supply chain availability, procurement lead times, or established vendor relationships.

Frequently Asked Questions (FAQ)

Q: Can ERJ-14NF3482U be used as a direct replacement for ERJ-S14F3482U?

A: Yes, from an electrical and mechanical standpoint. However, ERJ-14NF3482U carries "Not For New Designs" status. For new applications, use active-status alternatives.

Q: Are there physical differences between these parts?

A: Maximum seated height varies slightly: ERJ-S14F3482U and ERJ-14NF3482U are 0.028" (0.70mm), while CRCW121034K8FKEA is 0.024" (0.60mm). Both dimensions remain within the 1210 package specification and do not affect PCB layout compatibility.

Q: Do all substitutes meet automotive requirements?

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

Q: What is the significance of the anti-sulfur feature on ERJ-S14F3482U?

A: The anti-sulfur protection is a specific feature of the ERJ-S14F3482U. ERJ-14NF3482U and CRCW121034K8FKEA do not list this feature. If anti-sulfur protection is a design requirement, ERJ-S14F3482U is the specified choice.

Q: Are moisture sensitivity levels identical across all parts?

A: Yes. All three parts carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity constraints during storage or handling.
