ERJ-S14F48R7U Equivalent & Substitute Parts

Part Overview

The ERJ-S14F48R7U is a 48.7 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 899 units available in inventory.

Substitute parts become necessary when the primary part experiences supply constraints, extended lead times, or when design requirements permit selection from alternative manufacturers meeting identical electrical and mechanical specifications.

Substitute Part Grouping Explanation

Substitution eligibility for the ERJ-S14F48R7U is determined by strict equivalence across the following parameters:

• Resistance value: 48.7 Ohms
• Tolerance: ±1%
• Power rating: 0.5W (1/2W)
• Package format: 1210 (3225 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C to 155°C
• Automotive qualification: AEC-Q200
• RoHS compliance: ROHS3 Compliant
• Moisture sensitivity: MSL 1

The ERJ-14NF48R7U qualifies as a direct substitute based on complete alignment with all electrical and mechanical parameters. The primary distinction is product status: the ERJ-S14F48R7U is active production, while the ERJ-14NF48R7U is designated "Not For New Designs." The ERJ-14NF48R7U retains full functional equivalence and identical performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

For new design implementations, the ERJ-S14F48R7U is the preferred selection due to its active production status. This ensures long-term availability, consistent manufacturing processes, and manufacturer support throughout the product lifecycle.

The ERJ-14NF48R7U is functionally equivalent and maintains identical electrical and mechanical performance. However, its "Not For New Designs" designation indicates that Panasonic has transitioned this part to legacy status. Selection of the ERJ-14NF48R7U is appropriate only for replacement, repair, or continuation of existing designs where the part is already in production.

Both parts satisfy AEC-Q200 automotive qualification requirements and ROHS3 compliance mandates. Thermal performance, resistance stability, and package compatibility are identical across both options.

Frequently Asked Questions (FAQ)

Q: Can ERJ-14NF48R7U be used as a direct replacement for ERJ-S14F48R7U in new designs?

A: Electrically and mechanically, yes. However, the ERJ-14NF48R7U carries a "Not For New Designs" status. For new product development, the ERJ-S14F48R7U is the appropriate selection to ensure long-term supply chain stability and manufacturer support.

Q: Are there differences in thermal performance between these parts?

A: No. Both parts share identical temperature coefficients (±100ppm/°C) and operating temperature ranges (-55°C to 155°C). Thermal behavior is equivalent.

Q: Do both parts meet automotive qualification standards?

A: Yes. Both the ERJ-S14F48R7U and ERJ-14NF48R7U carry AEC-Q200 automotive qualification and are suitable for automotive applications.

Q: What is the significance of the "Not For New Designs" status?

A: This designation indicates that Panasonic has discontinued active development and promotion of the ERJ-14NF48R7U. While existing inventory remains available and the part functions identically to the active ERJ-S14F48R7U, new designs should specify the active production part to avoid future obsolescence.

Q: Are the package dimensions identical?

A: Yes. Both parts use the 1210 (3225 Metric) package with identical footprints: 0.126" L x 0.098" W (3.20mm x 2.50mm) and maximum seated height of 0.028" (0.70mm).

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

A: Yes. Both parts are rated MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.
