ERJ-S1DF1962U Equivalent & Substitute Parts

Part Overview

The ERJ-S1DF1962U is a 19.6 kOhms ±1% thick film chip resistor rated at 0.75W (3/4W) in a 2010 (5025 Metric) package. This component is manufactured by Panasonic Electronic Components and is designed for automotive applications with AEC-Q200 qualification and anti-sulfur protection. The part is currently in active production status with 1,069 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 that meet the same electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ERJ-S1DF1962U is determined by strict equivalence across the following parameters:

• Resistance value: 19.6 kOhms
• Tolerance: ±1%
• Power rating: 0.75W (3/4W)
• 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 (Unlimited)

The ERJ-12SF1962U meets all these criteria and is therefore a direct functional equivalent. Differences in product status and series designation do not affect electrical or mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

The ERJ-S1DF1962U is the preferred selection for new designs due to its active production status. The ERJ-12SF1962U is electrically and mechanically equivalent but carries a "Not For New Designs" status, indicating it is in a mature or declining production phase.

For applications requiring long-term supply assurance and design continuity, the ERJ-S1DF1962U should be the primary component selection. The ERJ-12SF1962U may be considered for legacy system maintenance, repair, or retrofit applications where the substitute part is already qualified in the existing design.

Both parts meet AEC-Q200 automotive qualification and ROHS3 compliance requirements, ensuring suitability for regulated automotive and industrial environments.

Frequently Asked Questions (FAQ)

Q: Can ERJ-12SF1962U be used as a direct replacement for ERJ-S1DF1962U in new designs?

A: Electrically and mechanically, yes. Both parts are identical in resistance, tolerance, power rating, package dimensions, and operating specifications. However, the ERJ-12SF1962U carries a "Not For New Designs" status. New designs should specify the ERJ-S1DF1962U to ensure long-term supply availability and design continuity.

Q: Are there any differences in automotive qualification between these parts?

A: No. Both the ERJ-S1DF1962U and ERJ-12SF1962U carry AEC-Q200 qualification and are suitable for automotive applications.

Q: Do these parts have identical physical dimensions?

A: Yes. Both parts are packaged in the 2010 (5025 Metric) case with identical length (0.197"), width (0.098"), and maximum seated height (0.028").

Q: What is the significance of the "Not For New Designs" status on the ERJ-12SF1962U?

A: This designation indicates the part is in a mature production phase and may have limited future availability. It does not reflect any technical deficiency but rather a product lifecycle decision by the manufacturer.

Q: Are both parts RoHS compliant?

A: Yes. Both the ERJ-S1DF1962U and ERJ-12SF1962U are ROHS3 compliant and REACH unaffected.

Q: What is the moisture sensitivity level for these resistors?

A: Both parts have MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.
