ERJ-S14F1621U Equivalent & Substitute Parts

Part Overview

The ERJ-S14F1621U is a 1.62 kOhms ±1% thick film chip resistor manufactured by Panasonic Electronic Components in the 1210 (3225 Metric) package format. This component is rated for 0.5W power dissipation and meets AEC-Q200 automotive qualification standards with anti-sulfur protection. The part is currently in Active product status with 968 units available in stock.

Substitute parts become necessary when the primary part experiences supply constraints, extended lead times, or when design flexibility permits component sourcing from alternative manufacturers while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ERJ-S14F1621U is determined by strict equivalence across the following parameters:

• Resistance value: 1.62 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, manufacturer, and inventory availability do not affect electrical or mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

For new designs, the ERJ-S14F1621U (Panasonic, Active status) is the primary selection. The CRCW12101K62FKEA (Vishay Dale, Active status) serves as a direct electrical and mechanical equivalent with identical performance parameters and certifications.

The ERJ-14NF1621U (Panasonic, Not For New Designs status) is electrically and mechanically equivalent but is designated as obsolete for new design applications. This part is suitable only for legacy system maintenance or replacement scenarios where the original part number must be preserved.

All three parts satisfy automotive AEC-Q200 qualification, ROHS3 compliance, and MSL 1 moisture sensitivity requirements. The seated height difference between the Panasonic ERJ-S14F1621U (0.70mm) and Vishay Dale CRCW12101K62FKEA (0.60mm) does not affect PCB assembly compatibility for standard 1210 package footprints.

Frequently Asked Questions (FAQ)

Q: Can ERJ-14NF1621U replace ERJ-S14F1621U in new designs?

A: No. The ERJ-14NF1621U carries a "Not For New Designs" status. While electrically and mechanically equivalent, it is designated as obsolete for new applications. Use only for legacy system support or direct replacement of existing assemblies.

Q: Is CRCW12101K62FKEA a suitable substitute for ERJ-S14F1621U?

A: Yes. The CRCW12101K62FKEA meets all electrical specifications (1.62 kOhms ±1%, 0.5W), operates across the same temperature range (-55°C ~ 155°C), carries AEC-Q200 automotive qualification, and is packaged in the 1210 (3225 Metric) format. Both parts are Active status and ROHS3 compliant.

Q: Does the height difference between ERJ-S14F1621U and CRCW12101K62FKEA affect PCB assembly?

A: No. The seated height difference (0.70mm versus 0.60mm) is within standard 1210 package tolerance and does not impact PCB footprint compatibility or assembly processes.

Q: Are all substitute parts AEC-Q200 qualified?

A: Yes. All listed substitute parts carry AEC-Q200 automotive qualification and are suitable for automotive applications requiring this certification.

Q: What is the significance of MSL 1 rating for these parts?

A: MSL 1 (Moisture Sensitivity Level 1) indicates unlimited shelf life with no moisture bake-out requirement prior to soldering. All listed parts share this rating.
