ERJ-S1TF8873U Equivalent & Substitute Parts

Part Overview

The ERJ-S1TF8873U is an 887 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 655 units in stock.

Substitute parts become necessary when the primary part reaches end-of-life, experiences supply constraints, or when design flexibility is required for cost optimization while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ERJ-S1TF8873U is determined by strict equivalence across the following parameters:

• Resistance value: 887 kOhms
• Tolerance: ±1%
• Power rating: 1W
• Package: 2512 (6432 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

The ERJ-1TNF8873U meets all electrical and mechanical parameters required for direct substitution. This part differs only in series designation (ERJ-1TN vs. ERJ-S1T) and product status classification, with no impact on functional performance or reliability characteristics.

Parameter Comparison

Engineering Selection Recommendations

The ERJ-1TNF8873U is electrically and mechanically equivalent to the ERJ-S1TF8873U across all specified parameters. Both parts maintain identical resistance, tolerance, power rating, package dimensions, temperature characteristics, and automotive qualification standards.

The primary distinction is product status: ERJ-S1TF8873U is designated as Active, while ERJ-1TNF8873U is classified as Not For New Designs. For ongoing production and new design implementations, the ERJ-S1TF8873U remains the preferred selection. The ERJ-1TNF8873U is suitable for legacy system support, maintenance applications, or situations where existing inventory must be utilized.

Both parts satisfy ROHS3 compliance and AEC-Q200 automotive reliability requirements. Selection between these parts should be based on design phase (new vs. legacy) and supply availability rather than electrical performance considerations.

Frequently Asked Questions (FAQ)

Q: Can ERJ-1TNF8873U be used as a direct replacement for ERJ-S1TF8873U in new designs?

A: Electrically and mechanically, yes. However, ERJ-1TNF8873U carries a "Not For New Designs" status. For new product development, ERJ-S1TF8873U is the appropriate selection to ensure long-term supply continuity and manufacturer support.

Q: Are there differences in reliability or performance between these parts?

A: No. Both parts are manufactured by Panasonic, share identical electrical specifications (887 kOhms ±1%, 1W, ±100ppm/°C), and carry AEC-Q200 automotive qualification. Performance and reliability characteristics are equivalent.

Q: What is the significance of the anti-sulfur feature on ERJ-S1TF8873U?

A: The anti-sulfur coating provides enhanced protection against sulfur-containing environmental contaminants, extending component life in harsh automotive and industrial environments. ERJ-1TNF8873U does not explicitly list this feature.

Q: Are both parts compatible with the same PCB footprint?

A: Yes. Both parts use the 2512 (6432 Metric) package with identical dimensions: 0.252" L x 0.126" W (6.40mm x 3.20mm) and maximum seated height of 0.028" (0.70mm). PCB layout and assembly processes require no modification.

Q: What is the moisture sensitivity difference between these parts?

A: Both parts have MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. Standard handling and storage procedures apply equally to both parts.

Q: Can these parts be mixed in the same production batch?

A: From an electrical and mechanical standpoint, yes. However, traceability and quality documentation practices may require segregation based on part number and manufacturer lot codes for compliance and warranty purposes.
