Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ERJ-S03F1052V are qualified based on the following criteria:

• Resistance Value: Exact match at 10.5 kOhms
• Tolerance: ±1% precision grade
• Power Rating: 0.1W (1/10W) minimum
• Package: 0603 (1608 Metric) form factor
• Composition: Thick film construction
• Temperature Coefficient: ±100ppm/°C
• Operating Temperature: -55°C ~ 155°C range
• RoHS Compliance: ROHS3 Compliant
• Moisture Sensitivity: MSL 1 (Unlimited)

All identified substitutes meet these electrical and mechanical parameters, ensuring functional equivalence in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed are active products with ROHS3 compliance and MSL 1 rating. Selection among equivalents may be based on:

• Availability: RMCF0603FT10K5 (Stackpole) offers highest inventory at 537,177 units
• Automotive Qualification: ERJ-3EKF1052V, CRCW060310K5FKEA, and RMCF0603FT10K5 carry AEC-Q200 ratings matching the original specification
• Manufacturer Preference: Panasonic ERJ-3EKF1052V maintains original manufacturer continuity with 68,759 units available
• Feature Set: AC0603FR-0710K5L and RC0603FR-0710K5L include moisture-resistant construction; CR0603-FX-1052ELF includes moisture-resistant features

All parts maintain identical electrical performance within the specified tolerance and temperature operating range.

Frequently Asked Questions (FAQ)

Q: Can ERJ-3EKF1052V replace ERJ-S03F1052V directly?

A: Yes. Both are Panasonic products with identical electrical specifications (10.5 kOhms ±1%, 0.1W, 0603 package), temperature coefficient (±100ppm/°C), and operating range (-55°C ~ 155°C). The primary difference is the series designation (ERJ-3EK vs. ERJ-S03), but electrical and mechanical parameters are equivalent.

Q: Are there differences in physical dimensions between substitute parts?

A: Dimensions are nominally equivalent across all parts. Standard 0603 package dimensions are 0.063" L x 0.031" W (1.60mm x 0.80mm) with maximum seated height of 0.022" (0.55mm). CRCW060310K5FKEA and RMCF0603FT10K5 show minor variations (1.55mm length, 0.85mm or 0.80mm width, 0.50mm or 0.022" height) within standard 0603 tolerance ranges and do not affect PCB layout compatibility.

Q: Which substitute parts have automotive qualification?

A: ERJ-3EKF1052V, CRCW060310K5FKEA, and RMCF0603FT10K5 carry AEC-Q200 ratings. The original ERJ-S03F1052V also includes AEC-Q200 qualification. AC0603FR-0710K5L, CR0603-FX-1052ELF, and RC0603FR-0710K5L do not list AEC-Q200 ratings but are suitable for non-automotive applications.

Q: What is the difference between Tape & Reel and Cut Tape packaging?

A: Tape & Reel (TR) packaging is supplied on continuous carrier tape for automated assembly. Cut Tape (CT) & Digi-Reel packaging provides smaller quantities cut from the reel. Both formats contain identical components; packaging choice depends on production volume and assembly equipment compatibility.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed parts, including the original ERJ-S03F1052V, are ROHS3 Compliant with MSL 1 (Unlimited) moisture sensitivity rating, meeting environmental and regulatory requirements for commercial and industrial applications.
