ERJ-S1DF82R5U Equivalent & Substitute Parts

Part Overview

The ERJ-S1DF82R5U is a 82.5 Ohm ±1% thick film chip resistor rated at 0.75W in a 2010 (5025 Metric) surface mount package. This component is manufactured by Panasonic Electronic Components and is qualified to the AEC-Q200 automotive standard with anti-sulfur coating. The part is currently in active production status with 783 units in stock.

Substitute parts are necessary when the primary part becomes unavailable, when design revisions require alternative sourcing, or when inventory constraints require qualified alternatives from the same manufacturer.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ERJ-S1DF82R5U is determined by the following parameters:

• Resistance value: 82.5 Ohms
• Tolerance: ±1%
• Power rating: 0.75W
• Package: 2010 (5025 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C
• AEC-Q200 automotive qualification
• RoHS3 compliance
• MSL rating: 1

The ERJ-12SF82R5U meets all electrical and mechanical parameters required for direct substitution. Both parts share identical resistance, tolerance, power rating, package dimensions, thermal characteristics, and automotive qualification. The primary distinction is product status and manufacturing series designation.

Parameter Comparison

Engineering Selection Recommendations

The ERJ-12SF82R5U is a qualified substitute for the ERJ-S1DF82R5U based on complete electrical and mechanical parameter equivalence. Both parts are manufactured by Panasonic Electronic Components and meet AEC-Q200 automotive qualification requirements.

For new designs, the ERJ-S1DF82R5U is the preferred selection due to its active product status. The ERJ-12SF82R5U carries a "Not For New Designs" designation and should be reserved for legacy design support, replacement inventory, or situations where the primary part is unavailable.

Both parts are RoHS3 compliant and carry MSL rating 1, indicating unlimited shelf life under standard storage conditions. Thermal and electrical performance characteristics are identical across the specified operating temperature range.

Frequently Asked Questions (FAQ)

Q: Can ERJ-12SF82R5U be used as a direct replacement for ERJ-S1DF82R5U in production?

A: Yes. The ERJ-12SF82R5U meets all electrical specifications (82.5 Ohms ±1%, 0.75W), thermal characteristics (±100ppm/°C, -55°C to 155°C), package dimensions (2010/5025 Metric), and automotive qualification (AEC-Q200). However, for new designs, ERJ-S1DF82R5U is the recommended choice due to active product status.

Q: What is the significance of the "Not For New Designs" status on ERJ-12SF82R5U?

A: This designation indicates the part is in mature or end-of-life phase. While fully functional and qualified, Panasonic recommends using ERJ-S1DF82R5U for new product development. The ERJ-12SF82R5U remains available for legacy support and replacement applications.

Q: Are there package or footprint differences between these parts?

A: No. Both parts use the 2010 (5025 Metric) package with identical dimensions: 0.197" L x 0.098" W (5.00mm x 2.50mm) and maximum seated height of 0.028" (0.70mm). PCB footprints are interchangeable.

Q: Do both parts meet automotive standards?

A: Yes. Both ERJ-S1DF82R5U and ERJ-12SF82R5U are qualified to AEC-Q200 automotive standard and are RoHS3 compliant. Both carry MSL rating 1 with unlimited moisture sensitivity protection.

Q: What is the difference in available inventory?

A: ERJ-S1DF82R5U has 783 units in stock, while ERJ-12SF82R5U has 10788 units available. Higher inventory availability of the substitute part may be relevant for high-volume procurement scenarios.
