ERJ-S1DF8252U Equivalent & Substitute Parts

Part Overview

The ERJ-S1DF8252U is a 82.5 kOhms ±1% thick film chip resistor rated at 0.75W (3/4W) in a 2010 (5025 Metric) surface mount 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 1085 units in stock.

Substitute parts become necessary when the primary part reaches end-of-life status, inventory constraints occur, or when design flexibility is required across multiple qualified alternatives that meet identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ERJ-S1DF8252U is determined by strict equivalence across the following parameters:

• Resistance value: 82.5 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-12SF8252U meets all these criteria and is therefore a direct electrical and mechanical equivalent. Differences in product status and series designation do not affect functional interchangeability in applications where the specified parameters are required.

Parameter Comparison

Engineering Selection Recommendations

The ERJ-S1DF8252U is the preferred selection for new designs due to its active production status. The ERJ-12SF8252U is electrically and mechanically equivalent but carries a "Not For New Designs" status, indicating it is in mature or declining production phase.

Both parts satisfy identical electrical specifications, dimensional requirements, and automotive compliance standards. Selection between these parts should be based on:

• Availability and lead time requirements
• Supply chain continuity for production volumes
• Design phase (new development versus legacy support)
• Inventory management and procurement strategy

For applications requiring long-term supply assurance, the active-status ERJ-S1DF8252U is the appropriate choice. The ERJ-12SF8252U remains suitable for replacement, repair, or retrofit applications where the substitute part is already qualified in existing designs.

Frequently Asked Questions (FAQ)

Q: Can ERJ-12SF8252U be used as a direct replacement for ERJ-S1DF8252U?

A: Yes. Both parts are electrically and mechanically identical across all specified parameters including resistance, tolerance, power rating, package dimensions, temperature coefficient, operating temperature range, and automotive certifications. The difference in product status does not affect functional performance.

Q: What does "Not For New Designs" mean for the ERJ-12SF8252U?

A: This status indicates the part is in mature production phase and may have limited availability or extended lead times. It is suitable for replacement and retrofit applications but should not be selected as the primary component for new product development.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both parts use the 2010 (5025 Metric) package with identical length (0.197" / 5.00mm), width (0.098" / 2.50mm), and maximum seated height (0.028" / 0.70mm).

Q: Do both parts meet automotive qualification requirements?

A: Yes. Both ERJ-S1DF8252U and ERJ-12SF8252U carry AEC-Q200 automotive qualification and are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating.

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

A: Yes. Identical package specifications, termination count, and electrical characteristics ensure interchangeability at the component level. No circuit design modifications are required.
