ERJ-S14F1742U Equivalent & Substitute Parts

Part Overview

The ERJ-S14F1742U is a 17.4 kOhms ±1% thick film chip resistor manufactured by Panasonic Electronic Components in the 1210 (3225 Metric) package format. This component is rated for 0.5W power dissipation and meets AEC-Q200 automotive qualification standards with anti-sulfur protection. The part is currently in active production status with 781 units in stock.

Substitute parts become necessary when the primary part reaches end-of-life status, inventory constraints occur, or design revisions require components from alternative product series. The ERJ-S14F1742U has documented equivalents within the Panasonic portfolio that maintain identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ERJ-S14F1742U is determined by strict equivalence across the following parameters:

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

The ERJ-14NF1742U meets all these criteria and qualifies as a direct electrical and mechanical equivalent. Differences in product series designation (ERJ-S14 versus ERJ-14N) reflect manufacturing line variations within Panasonic's resistor portfolio but do not affect functional compatibility in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

The ERJ-S14F1742U is the preferred selection for new designs due to its active production status. This part carries full manufacturing support and guaranteed long-term availability.

The ERJ-14NF1742U is electrically and mechanically equivalent but carries a "Not For New Designs" status. This designation indicates the part remains available for existing production and field service applications but should not be selected for new circuit designs. Use of ERJ-14NF1742U is appropriate only when supporting legacy equipment or when ERJ-S14F1742U availability is constrained.

Both parts maintain identical compliance certifications: AEC-Q200 automotive qualification, ROHS3 compliance, and unlimited moisture sensitivity rating. Thermal and electrical performance characteristics are equivalent across the specified operating range.

Frequently Asked Questions (FAQ)

Q: Can ERJ-14NF1742U be used as a direct replacement for ERJ-S14F1742U in new designs?

A: No. While ERJ-14NF1742U is electrically and mechanically equivalent, its "Not For New Designs" status means it should not be selected for new circuit development. ERJ-S14F1742U is the correct choice for new applications.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both parts use the 1210 (3225 Metric) package with identical length (0.126"), width (0.098"), and maximum seated height (0.028"). They are mechanically interchangeable on PCBs designed for this package format.

Q: Do both parts meet automotive qualification requirements?

A: Yes. Both ERJ-S14F1742U and ERJ-14NF1742U carry AEC-Q200 automotive qualification. The ERJ-S14F1742U additionally features anti-sulfur protection, which is not specified for the ERJ-14NF1742U.

Q: What is the significance of the product series designation (ERJ-S14 versus ERJ-14N)?

A: The series designation reflects different manufacturing lines within Panasonic's resistor portfolio. These designations do not affect electrical performance or mechanical compatibility. Both series meet identical specification requirements for this 17.4 kOhms value.

Q: Are there any compliance or certification differences?

A: Both parts are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating. Compliance certifications are equivalent. The primary difference is production status, not regulatory compliance.
