ERJ-S14F28R0U Equivalent & Substitute Parts

Part Overview

The ERJ-S14F28R0U is a 28 Ohm ±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 features anti-sulfur coating with AEC-Q200 automotive qualification. The part is currently in active production status with 813 units available in stock.

Substitute parts are identified when design requirements necessitate alternative sourcing due to inventory constraints, supply chain considerations, or specific feature requirements while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ERJ-S14F28R0U are qualified based on the following criteria:

Electrical Parameters: Resistance value (28 Ohms), tolerance (±1%), power rating (0.5W), temperature coefficient (±100ppm/°C), and operating temperature range (-55°C to 155°C) must be identical.

Mechanical Parameters: Package format (1210/3225 Metric), composition (thick film), and termination count (2) must match.

Compliance & Ratings: All substitute parts must maintain AEC-Q200 automotive qualification, ROHS3 compliance, and MSL 1 rating.

Allowed Variations: Product status may differ (Active vs. Not For New Designs). Additional features such as pulse withstanding capability or anti-sulfur coating represent enhancements that do not disqualify substitution.

Parameter Comparison

Engineering Selection Recommendations

ERJ-P14F28R0U is the primary substitute for new designs. This part maintains active production status, identical electrical and mechanical specifications, and adds pulse withstanding capability. It is suitable for applications requiring enhanced transient protection while maintaining full AEC-Q200 compliance.

ERJ-14NF28R0U is available as a secondary substitute with significantly higher inventory (10651 units). However, this part carries "Not For New Designs" status, indicating it is in mature or declining production phase. Selection of this part should be limited to legacy system support or high-volume applications where supply availability is the primary constraint.

Both substitute parts are electrically and mechanically interchangeable with the ERJ-S14F28R0U within the specified operating parameters and compliance framework.

Frequently Asked Questions (FAQ)

Q: Can ERJ-P14F28R0U replace ERJ-S14F28R0U in automotive applications?

A: Yes. Both parts meet AEC-Q200 automotive qualification, operate across -55°C to 155°C, and share identical electrical parameters (28 Ohms ±1%, 0.5W). The ERJ-P14F28R0U adds pulse withstanding capability, which does not create incompatibility.

Q: Why is ERJ-14NF28R0U marked "Not For New Designs"?

A: This designation indicates the part is in mature production phase. While electrically and mechanically equivalent, Panasonic recommends ERJ-S14F28R0U or ERJ-P14F28R0U for new circuit designs. ERJ-14NF28R0U remains suitable for replacement or legacy applications.

Q: Are all three parts in the same 1210 package?

A: Yes. All three parts use the 1210 (3225 Metric) package with identical dimensions (3.20mm L × 2.50mm W × 0.70mm H max), ensuring direct PCB footprint compatibility.

Q: What is the difference between anti-sulfur and pulse withstanding features?

A: Anti-sulfur coating (ERJ-S14F28R0U) protects against sulfur-containing environmental contaminants. Pulse withstanding (ERJ-P14F28R0U) enhances transient voltage protection. These are independent features; neither disqualifies substitution.

Q: Do all parts have the same moisture sensitivity rating?

A: Yes. All three parts carry MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.
