Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ERJ-S14F5902U is determined by strict equivalence across the following parameters:

• Resistance value: 59 kOhms
• 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 Compliant
• Moisture sensitivity: MSL 1

The ERJ-14NF5902U meets all electrical and mechanical parameters required for direct substitution. While the ERJ-14NF5902U carries a "Not For New Designs" status, it remains electrically and mechanically equivalent and is suitable for replacement applications, legacy system support, and field service scenarios.

Parameter Comparison

Engineering Selection Recommendations

The ERJ-S14F5902U is the preferred selection for new designs due to its active production status and anti-sulfur feature set. The ERJ-14NF5902U provides full electrical and mechanical equivalence and is suitable for replacement, field service, and legacy system applications where the "Not For New Designs" designation does not restrict use.

Both parts carry identical AEC-Q200 automotive qualification, RoHS3 compliance, and MSL 1 moisture sensitivity rating, ensuring compatibility in automotive and industrial applications requiring high reliability standards.

Frequently Asked Questions (FAQ)

Q: Can ERJ-14NF5902U replace ERJ-S14F5902U in new designs?

A: The ERJ-14NF5902U meets all electrical and mechanical specifications for direct substitution. However, the "Not For New Designs" status indicates Panasonic's recommendation to use the ERJ-S14F5902U for new product development. Selection depends on design phase and supply availability constraints.

Q: Are there differences in anti-sulfur coating between these parts?

A: The ERJ-S14F5902U explicitly includes anti-sulfur coating. The ERJ-14NF5902U specification does not list this feature. Both parts meet AEC-Q200 automotive qualification and operate across identical temperature ranges.

Q: Do both parts have the same physical dimensions?

A: Yes. Both parts are packaged in 1210 (3225 Metric) with identical dimensions: 0.126" L x 0.098" W (3.20mm x 2.50mm) and maximum seated height of 0.028" (0.70mm).

Q: Are these parts suitable for automotive applications?

A: Yes. Both parts carry AEC-Q200 automotive qualification and are rated for -55°C ~ 155°C operating temperature, meeting automotive reliability standards.

Q: What is the significance of MSL 1 rating?

A: MSL 1 (Unlimited) indicates these parts have unlimited shelf life and require no special moisture control during storage or handling, simplifying logistics and inventory management.
