Equivalent & Substitute Parts for ERJ-S1TF8202U

Part Overview

The ERJ-S1TF8202U is an 82 kOhms ±1% 1W chip resistor in 2512 (6432 Metric) package manufactured by Panasonic Electronic Components. This thick film resistor features anti-sulfur coating and automotive AEC-Q200 qualification, designed for high-reliability applications in automotive and industrial environments. The part is currently in active production status with 978 units in stock.

Equivalent and substitute parts become necessary when the primary part faces supply constraints, extended lead times, or when design flexibility permits the use of functionally compatible alternatives that meet the same electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ERJ-S1TF8202U is determined by strict equivalence across the following parameters:

• Resistance value: 82 kOhms
• Tolerance: ±1%
• Power rating: 1W
• Package type: 2512 (6432 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C
• RoHS compliance: ROHS3 Compliant
• Moisture sensitivity: MSL 1 (Unlimited)

All identified substitute parts meet these core electrical and mechanical parameters. Variations in specific features (such as anti-sulfur coating or automotive certification) do not disqualify substitution when the fundamental electrical performance and package compatibility remain identical.

Parameter Comparison

Engineering Selection Recommendations

For new designs, the ERJ-S1TF8202U remains the preferred choice due to its active product status and anti-sulfur coating with automotive AEC-Q200 qualification, providing enhanced reliability in harsh automotive environments.

The RC2512FK-0782KL from YAGEO is a direct functional equivalent with active product status. This part meets all electrical and mechanical specifications and is suitable for applications where the anti-sulfur feature is not a critical requirement.

The ERJ-1TNF8202U, while electrically and mechanically equivalent, carries a "Not For New Designs" status. This part should be used only in legacy system maintenance or when existing inventory constraints necessitate its use. New design implementations should avoid this part number.

Frequently Asked Questions (FAQ)

Q: Can ERJ-1TNF8202U be used as a direct replacement for ERJ-S1TF8202U in new designs?

A: No. Although ERJ-1TNF8202U is electrically and mechanically equivalent, it carries a "Not For New Designs" product status. New designs should use ERJ-S1TF8202U or RC2512FK-0782KL.

Q: What is the difference between ERJ-S1TF8202U and RC2512FK-0782KL?

A: Both parts are functionally equivalent with identical electrical specifications (82 kOhms ±1%, 1W, ±100ppm/°C). The primary difference is manufacturer: Panasonic versus YAGEO. ERJ-S1TF8202U includes anti-sulfur coating and automotive AEC-Q200 certification, while RC2512FK-0782KL features moisture-resistant construction. Both are ROHS3 compliant and suitable for -55°C to 155°C operation.

Q: Are the physical dimensions identical across all three parts?

A: The parts are dimensionally compatible within the 2512 (6432 Metric) package specification. ERJ-S1TF8202U and ERJ-1TNF8202U share identical dimensions (0.252" L x 0.126" W, 0.028" max height). RC2512FK-0782KL has slightly tighter tolerances (0.250" L x 0.122" W, 0.026" max height) but remains within the 2512 package family and is PCB-compatible.

Q: Which substitute part should be selected for automotive applications?

A: ERJ-S1TF8202U is the primary choice for automotive applications due to AEC-Q200 qualification and anti-sulfur coating. RC2512FK-0782KL is acceptable for non-critical automotive subsystems where AEC-Q200 certification is not mandated.

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

A: All three parts have MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. These parts can be stored and handled without special moisture control measures.
