Equivalent & Substitute Parts for ERJ-S1DF1621U

Part Overview

The ERJ-S1DF1621U is a 1.62 kOhms ±1% thick film chip resistor rated at 0.75W in a 2010 (5025 Metric) surface mount package. Manufactured by Panasonic Electronic Components, this resistor features anti-sulfur coating and automotive AEC-Q200 qualification, making it suitable for demanding automotive and industrial applications. The part is currently in active production status with 1058 units in stock.

Substitute parts become necessary when the primary part experiences supply constraints, extended lead times, or when design flexibility permits the use of functionally equivalent alternatives from different manufacturers while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ERJ-S1DF1621U is determined by strict equivalence across the following critical parameters:

• Resistance value: 1.62 kOhms
• Tolerance: ±1%
• Power rating: 0.75W
• Package: 2010 (5025 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 parameters without exception. Substitution is based solely on functional and mechanical equivalence; no performance trade-offs or derating considerations apply.

Parameter Comparison

Engineering Selection Recommendations

For new designs, the ERJ-S1DF1621U (Panasonic, Active status) is the primary selection. This part maintains full production support and is recommended for all applications requiring long-term supply assurance.

The CRCW20101K62FKEF (Vishay Dale) is a fully qualified alternative with Active product status. This part is electrically and mechanically equivalent and suitable for new designs when supply or lead time considerations favor the Vishay Dale source.

The ERJ-12SF1621U (Panasonic) is marked as Not For New Designs and should be used only in legacy applications or when existing inventory must be consumed. This part is electrically equivalent but carries a discontinued design status that may impact future availability and support.

Frequently Asked Questions (FAQ)

Q: Can ERJ-12SF1621U be used in new designs? A: No. The ERJ-12SF1621U carries a "Not For New Designs" status. For new applications, use either the ERJ-S1DF1621U or CRCW20101K62FKEF.

Q: Are all three parts mechanically interchangeable? A: Yes. All three parts use the identical 2010 (5025 Metric) package with matching footprint dimensions (0.197" L x 0.098" W, 5.00mm x 2.50mm) and maximum seated height (0.028" / 0.70mm).

Q: Do the substitute parts meet automotive requirements? A: Yes. All three parts carry AEC-Q200 automotive qualification and are suitable for automotive applications.

Q: What is the difference between ERJ-S1DF1621U and ERJ-12SF1621U? A: Both are Panasonic products with identical electrical specifications. The primary difference is product status: ERJ-S1DF1621U is Active, while ERJ-12SF1621U is Not For New Designs. The ERJ-S1DF1621U also includes anti-sulfur coating.

Q: Can I substitute based on manufacturer preference? A: Yes, provided the substitute meets all specified parameters. The CRCW20101K62FKEF from Vishay Dale is fully equivalent and carries Active status, making it suitable for direct substitution.

Q: Are there any compliance differences between the parts? A: No. All three parts are ROHS3 Compliant, REACH Unaffected, and carry MSL 1 (Unlimited) moisture sensitivity rating.
