Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ERJ-S03F17R8V are qualified based on the following criteria:

• Resistance value: 17.8 Ohms
• Tolerance: ±1%
• Power rating: 0.1W (1/10W)
• Package: 0603 (1608 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C
• RoHS3 compliance
• Moisture Sensitivity Level 1

All identified substitutes meet these core electrical and mechanical parameters. Variations in specific features (such as anti-sulfur versus moisture-resistant construction) do not affect functional equivalence for standard applications within the specified operating conditions.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed are active products with ROHS3 compliance and Moisture Sensitivity Level 1 rating. Selection among these equivalents should be based on:

• Availability: RC0603FR-0717R8L (YAGEO) offers the highest inventory at 122,998 units. ERJ-3EKF17R8V (Panasonic) provides 33,127 units as an alternative from the same manufacturer family.
• Automotive qualification: ERJ-S03F17R8V, ERJ-3EKF17R8V, CRCW060317R8FKEA, and RMCF0603FT17R8 carry AEC-Q200 ratings for automotive applications.
• Dimensional consistency: Most substitutes maintain identical or near-identical package dimensions (1.60 x 0.80 mm or 1.55 x 0.85 mm), ensuring PCB layout compatibility.

Frequently Asked Questions (FAQ)

Q: Can ERJ-3EKF17R8V replace ERJ-S03F17R8V directly?

A: Yes. Both parts are manufactured by Panasonic, share identical electrical specifications (17.8 Ω ±1%, 0.1W), operate across -55°C to 155°C, and are packaged in 0603 (1608 Metric). The primary difference is the series designation (ERJ-3EK versus ERJ-S03), with ERJ-3EKF17R8V offering higher inventory availability.

Q: Are the Bourns CR0603-FX-17R8ELF and YAGEO RC0603FR-0717R8L suitable for automotive applications?

A: CR0603-FX-17R8ELF is not rated for automotive use; it features moisture-resistant construction. RC0603FR-0717R8L is also not AEC-Q200 rated. Both are functionally equivalent in electrical performance but lack automotive qualification. Use only if automotive compliance is not required.

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

A: Anti-sulfur construction (ERJ-S03F17R8V) protects against sulfur-containing atmospheric corrosion. Moisture-resistant construction (CR0603-FX-17R8ELF, RC0603FR-0717R8L) protects against moisture ingress. Both are thick film resistors with identical electrical performance. Selection depends on environmental exposure requirements.

Q: Do all substitutes fit the same PCB footprint?

A: Yes. All parts use 0603 (1608 Metric) package with two terminations. Dimensional variations (1.60 x 0.80 mm versus 1.55 x 0.85 mm) are within standard PCB design tolerances and do not affect placement or soldering.

Q: Which substitute offers the best supply availability?

A: RC0603FR-0717R8L (YAGEO) has the highest inventory at 122,998 units. For automotive-qualified alternatives, ERJ-3EKF17R8V (Panasonic) provides 33,127 units.
