ERJ-S14F17R4U Equivalent & Substitute Parts

Part Overview

The ERJ-S14F17R4U is a 17.4 Ohm ±1% 0.5W thick film chip resistor in 1210 (3225 Metric) package manufactured by Panasonic Electronic Components. This component is rated for automotive applications under AEC-Q200 and features anti-sulfur properties. The part is currently in active production status. Substitute parts may be required due to inventory constraints, supply chain discontinuation of legacy series, or design flexibility across qualified alternatives that meet identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ERJ-S14F17R4U are qualified based on the following critical parameters that must remain identical:

• Resistance value: 17.4 Ohms
• Tolerance: ±1%
• Power rating: 0.5W (1/2W)
• Package: 1210 (3225 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C
• Automotive qualification: AEC-Q200
• RoHS compliance: ROHS3
• Moisture sensitivity: MSL 1

The following substitute parts meet all these criteria and are therefore electrically and mechanically interchangeable with the main part number.

Parameter Comparison

Engineering Selection Recommendations

All three parts listed meet the complete set of electrical and mechanical specifications required for direct substitution in applications designed for the ERJ-S14F17R4U.

For new designs, ERJ-S14F17R4U (Panasonic, Active status) and AC1210FR-0717R4L (YAGEO, Active status) are preferred due to their active production status and ongoing manufacturer support.

ERJ-14NF17R4U (Panasonic) carries a "Not For New Designs" status, indicating this series is in legacy phase. This part remains electrically and mechanically equivalent but should be used only in applications requiring continuity with existing inventory or legacy system maintenance.

All three parts carry ROHS3 compliance, AEC-Q200 automotive qualification, and MSL 1 rating, confirming suitability for automotive and industrial applications across the specified temperature range.

Frequently Asked Questions (FAQ)

Q: Can ERJ-14NF17R4U be used as a direct replacement for ERJ-S14F17R4U?

A: Yes. Both parts share identical electrical specifications (17.4 Ohms ±1%, 0.5W), mechanical package (1210), temperature coefficient (±100ppm/°C), operating range (-55°C ~ 155°C), and automotive certifications (AEC-Q200). The primary difference is product status: ERJ-14NF17R4U is marked "Not For New Designs," indicating the series is in legacy phase. For new designs, ERJ-S14F17R4U is recommended.

Q: Is AC1210FR-0717R4L from YAGEO compatible with the Panasonic ERJ-S14F17R4U?

A: Yes. The YAGEO AC1210FR-0717R4L meets all critical parameters: 17.4 Ohms ±1%, 0.5W, 1210 package, ±100ppm/°C temperature coefficient, -55°C ~ 155°C operating range, AEC-Q200 rating, and ROHS3 compliance. Both manufacturers' parts are electrically and mechanically interchangeable. The AC series is in active production status.

Q: What are the key parameters that determine substitutability for this resistor?

A: Substitutability is determined by: resistance value (17.4 Ohms), tolerance (±1%), power rating (0.5W), package type (1210), composition (thick film), temperature coefficient (±100ppm/°C), operating temperature range (-55°C ~ 155°C), automotive qualification (AEC-Q200), and compliance certifications (ROHS3, MSL 1). All substitute parts must match these parameters exactly.

Q: Are there dimensional differences between these parts?

A: Minor dimensional variations exist. ERJ-S14F17R4U and ERJ-14NF17R4U are specified at 0.126" L x 0.098" W (3.20mm x 2.50mm) with 0.028" (0.70mm) maximum seated height. AC1210FR-0717R4L is specified at 0.122" L x 0.102" W (3.10mm x 2.60mm) with 0.024" (0.60mm) maximum seated height. These variations remain within 1210 package tolerances and do not affect PCB footprint compatibility or electrical performance.

Q: Which part should be selected for new automotive designs?

A: For new designs, select either ERJ-S14F17R4U (Panasonic, Active) or AC1210FR-0717R4L (YAGEO, Active). Both carry active production status, full AEC-Q200 automotive qualification, and ROHS3 compliance. ERJ-14NF17R4U should not be used for new designs due to its legacy status.
