Part Overview

The ERJ-S03F1072V is a 10.7 kOhms ±1% thick film chip resistor manufactured by Panasonic Electronic Components in 0603 (1608 Metric) package format. This component is rated for 0.1W power dissipation and features anti-sulfur coating with automotive AEC-Q200 qualification. The part is currently active in production with 832 units in stock.

Substitute parts are necessary when the primary part becomes unavailable, when supply chain constraints require alternative sourcing, or when design flexibility permits equivalent components from qualified manufacturers. All substitute parts listed maintain identical electrical specifications and package dimensions to ensure direct board-level compatibility.

Substitute Part Grouping Explanation

Substitution eligibility for the ERJ-S03F1072V is determined by strict equivalence across the following parameters:

• Resistance value: 10.7 kOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Power rating: 0.1W (exact match required)
• Package: 0603 (1608 Metric) (exact match required)
• Composition: Thick Film (exact match required)
• Temperature coefficient: ±100ppm/°C (exact match required)
• Operating temperature range: -55°C to 155°C (exact match required)
• Moisture sensitivity: MSL 1 (exact match required)

All substitute parts listed meet these criteria. Variations in physical dimensions within tolerance, manufacturer-specific features (such as anti-sulfur or moisture-resistant coatings), and product status are noted but do not affect electrical interchangeability at the board level.

Engineering Selection Recommendations

For applications requiring ROHS3 compliance, the following parts are qualified: ERJ-3EKF1072V (Panasonic), AC0603FR-0710K7L (YAGEO), CR0603-FX-1072ELF (Bourns), CRCW060310K7FKEA (Vishay Dale), CRCW060310K7FKEB (Vishay Dale), RC0603FR-0710K7L (YAGEO), and RMCF0603FT10K7 (Stackpole Electronics). CRCW060310K7FKTA is RoHS non-compliant and should not be used in applications with RoHS requirements.

For automotive applications requiring AEC-Q200 qualification, the following parts are rated: ERJ-S03F1072V, ERJ-3EKF1072V, CRCW060310K7FKEA, CRCW060310K7FKEB, CRCW060310K7FKTA, and RMCF0603FT10K7.

CRCW060310K7FKEB is listed as discontinued at DiGi Electronics and should be avoided for new designs requiring long-term availability assurance.

All remaining active parts with ROHS3 compliance and current product status are suitable for direct substitution in non-automotive applications. Selection among these parts may be based on inventory availability, lead time, or established supplier relationships.

Frequently Asked Questions (FAQ)

Q: Can ERJ-3EKF1072V replace ERJ-S03F1072V directly on the PCB?

A: Yes. Both parts share identical electrical specifications (10.7 kOhms ±1%, 0.1W, ±100ppm/°C, -55°C to 155°C) and 0603 package dimensions. The primary difference is the series designation (ERJ-3EK versus ERJ-S03) and the absence of anti-sulfur coating on the ERJ-3EKF1072V. For standard applications, this substitution is electrically and mechanically compatible.

Q: Are all substitute parts automotive-qualified?

A: No. Only ERJ-S03F1072V, ERJ-3EKF1072V, CRCW060310K7FKEA, CRCW060310K7FKEB, CRCW060310K7FKTA, and RMCF0603FT10K7 carry AEC-Q200 automotive qualification. AC0603FR-0710K7L, CR0603-FX-1072ELF, and RC0603FR-0710K7L do not list AEC-Q200 ratings. For automotive applications, use only AEC-Q200 qualified parts.

Q: What is the difference between anti-sulfur and moisture-resistant coatings?

A: Anti-sulfur coating protects against sulfur-containing atmospheric contaminants common in industrial environments. Moisture-resistant coating protects against humidity and condensation. Both are protective features; the choice depends on the specific environmental conditions of the application. Electrically, both coatings do not affect component performance.

Q: Why is CRCW060310K7FKTA listed as RoHS non-compliant?

A: CRCW060310K7FKTA is marked as RoHS non-compliant and REACH Affected. This part should not be used in applications subject to RoHS Directive requirements. Use ROHS3 compliant alternatives for regulatory compliance.

Q: Can I use CRCW060310K7FKEB for new designs?

A: CRCW060310K7FKEB is discontinued at DiGi Electronics. While 36,649 units remain in stock, this part is not recommended for new designs requiring long-term component availability. Use active alternatives such as CRCW060310K7FKEA or RMCF0603FT10K7 instead.

Q: Do all substitute parts have the same physical dimensions?

A: All parts use the 0603 (1608 Metric) package. Minor dimensional variations exist within tolerance: most parts measure 0.063" L × 0.031" W (1.60mm × 0.80mm), while CRCW060310K7FKEA and CRCW060310K7FKEB measure 0.061" L × 0.033" W (1.55mm × 0.85mm), and RMCF0603FT10K7 measures 0.061" L × 0.031" W (1.55mm × 0.80mm). These variations are within 0603 package tolerance and do not affect PCB placement or functionality.

Q: Which substitute part has the highest inventory availability?

A: RC0603FR-0710K7L (YAGEO) has the highest inventory with 128,815 units in stock, followed by RMCF0603FT10K7 (Stackpole Electronics) with 200,590 units. Both are active products with ROHS3 compliance.
