Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ERJ-S14F9312U is determined by strict equivalence across the following critical parameters: resistance value (93.1 kOhms), tolerance (±1%), power rating (0.5W), package format (1210 / 3225 Metric), composition (thick film), temperature coefficient (±100ppm/°C), operating temperature range (-55°C to 155°C), and automotive qualification (AEC-Q200). The substitute part ERJ-14NF9312U meets all electrical and mechanical specifications. Substitution logic is based solely on these provided parameters without consideration of performance characteristics beyond the specified data.

Parameter Comparison

Engineering Selection Recommendations

The ERJ-S14F9312U is the primary selection for new designs due to its active product status and ROHS3 compliance. The ERJ-14NF9312U substitute part is electrically and mechanically equivalent across all specified parameters but carries a "Not For New Designs" designation and does not meet ROHS3 compliance requirements. Selection between these parts should be based on design phase requirements and regulatory compliance mandates. For applications requiring RoHS compliance, the ERJ-S14F9312U is the appropriate choice. For legacy system support or supply chain alternatives where RoHS compliance is not a constraint, the ERJ-14NF9312U provides functional equivalence.

Frequently Asked Questions (FAQ)

Q: Can ERJ-14NF9312U be used as a direct replacement for ERJ-S14F9312U in new designs?

A: The ERJ-14NF9312U is electrically and mechanically equivalent but carries a "Not For New Designs" status and is not ROHS3 compliant. Use in new designs should be evaluated against project compliance requirements.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both parts are packaged in the 1210 (3225 Metric) format with identical dimensions of 0.126" L x 0.098" W (3.20mm x 2.50mm) and maximum seated height of 0.028" (0.70mm).

Q: Do both parts meet automotive qualification standards?

A: Yes. Both ERJ-S14F9312U and ERJ-14NF9312U carry AEC-Q200 automotive qualification and operate across the identical temperature range of -55°C to 155°C.

Q: What is the key difference between these substitute parts?

A: The primary differences are product status (Active vs. Not For New Designs) and RoHS compliance (ROHS3 Compliant vs. RoHS non-compliant). All electrical and mechanical parameters are identical.

Q: Can these parts be used interchangeably on the same PCB assembly line?

A: Both parts use identical Tape & Reel (TR) packaging and have the same physical footprint, allowing mechanical interchangeability on standard pick-and-place equipment. Compliance and design phase requirements should guide selection.
