Substitute Part Grouping Explanation

Substitution eligibility for the ESR18EZPF3321 is determined by strict equivalence across the following critical parameters:

• Resistance value: 3.32 kOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Power rating: 0.5W minimum
• Package format: 1206 (3216 Metric) footprint compatibility
• Composition: Thick film construction
• Temperature coefficient: ±100ppm/°C or better
• Operating temperature range: -55°C to 155°C minimum
• Automotive compliance: AEC-Q200 certification mandatory
• RoHS compliance: ROHS3 Compliant
• Moisture sensitivity: MSL 1 or better

The RCS12063K32FKEA from Vishay Dale meets all substitution criteria as a direct equivalent component.

Parameter Comparison

Engineering Selection Recommendations

Both the ESR18EZPF3321 and RCS12063K32FKEA are qualified for automotive applications under AEC-Q200 standard and maintain full ROHS3 compliance. Selection between these components should be based on:

• Supply availability and lead time requirements
• Procurement cost and volume pricing
• Existing supplier relationships and quality agreements
• PCB assembly process compatibility with either manufacturer's specifications

The RCS12063K32FKEA from Vishay Dale currently maintains higher inventory availability (3043 units) compared to the ESR18EZPF3321 (906 units), which may influence selection for high-volume production schedules.

Frequently Asked Questions (FAQ)

Q: Can RCS12063K32FKEA be used as a direct replacement for ESR18EZPF3321 in automotive applications?

A: Yes. Both components share identical electrical specifications (3.32 kOhms ±1%, 0.5W), mechanical dimensions (1206 package), and automotive qualification (AEC-Q200). PCB footprint compatibility is guaranteed.

Q: Are there any differences in temperature performance between these two parts?

A: No. Both components operate across the identical temperature range (-55°C to 155°C) with matching temperature coefficient (±100ppm/°C).

Q: What is the significance of the 1206 package designation?

A: The 1206 (3216 Metric) package specifies the physical dimensions of the chip resistor: 0.126" length × 0.063" width (3.20mm × 1.60mm). This standardized package ensures mechanical and electrical compatibility across both components on the same PCB footprint.

Q: Do both parts meet the same moisture sensitivity requirements?

A: Yes. Both the ESR18EZPF3321 and RCS12063K32FKEA are rated MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.

Q: Are there any compliance or certification differences between these substitutes?

A: No. Both components are ROHS3 compliant, AEC-Q200 qualified, and carry identical REACH and ECCN classifications (REACH Unaffected, EAR99).
