ERJ-S1DF14R7U Equivalent & Substitute Parts

Part Overview

The ERJ-S1DF14R7U is a 14.7 Ohm ±1% thick film chip resistor rated at 0.75W in a 2010 (5025 Metric) surface mount package. This component is manufactured by Panasonic Electronic Components and is designed for automotive applications with AEC-Q200 qualification and anti-sulfur protection. The part is currently in active production status with 857 units in stock.

Substitute parts are necessary when the primary part becomes unavailable, when design requirements shift to legacy component series, or when inventory constraints require alternative sourcing from qualified manufacturers.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the ERJ-S1DF14R7U is valid when the replacement part maintains the following critical parameters:

• Resistance value: 14.7 Ohms
• Tolerance: ±1%
• Power rating: 0.75W minimum
• Package: 2010 (5025 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C minimum
• Automotive qualification: AEC-Q200
• RoHS compliance: ROHS3 Compliant

The ERJ-12SF14R7U qualifies as a direct substitute based on matching all electrical and mechanical parameters. The primary distinction is product status and series designation.

Parameter Comparison

Engineering Selection Recommendations

The ERJ-S1DF14R7U is the preferred selection for new designs due to its active product status. The ERJ-12SF14R7U is electrically and mechanically equivalent and maintains full AEC-Q200 automotive qualification and ROHS3 compliance.

Selection of ERJ-12SF14R7U is appropriate when:

• The ERJ-S1DF14R7U is unavailable or subject to extended lead times
• Existing designs currently utilize the ERJ-12S series
• Higher inventory availability is required for production scaling
• Legacy system maintenance or field replacement is necessary

Both parts are manufactured by Panasonic Electronic Components and carry identical electrical specifications, package dimensions, and automotive certifications. The distinction between active and not-for-new-designs status reflects Panasonic's product lifecycle management rather than technical performance differences.

Frequently Asked Questions (FAQ)

Q: Can ERJ-12SF14R7U be used as a direct replacement for ERJ-S1DF14R7U in automotive applications?

A: Yes. Both parts meet AEC-Q200 automotive qualification, maintain identical resistance (14.7 Ohms ±1%), power rating (0.75W), and operating temperature range (-55°C ~ 155°C). The 2010 package dimensions and thick film composition are identical.

Q: What is the difference between the ERJ-S1D and ERJ-12S series?

A: The ERJ-S1D series represents the current generation with active production status. The ERJ-12S series is a legacy generation designated as not-for-new-designs. Electrical and mechanical specifications are equivalent.

Q: Are there any compliance or certification differences between these parts?

A: No. Both parts are ROHS3 compliant, REACH unaffected, and carry AEC-Q200 automotive qualification. Moisture sensitivity level is identical at MSL 1 (unlimited).

Q: Can these parts be used interchangeably on the same PCB assembly?

A: Yes. Both parts use the 2010 (5025 Metric) surface mount package with identical footprint dimensions (5.00mm L x 2.50mm W) and maximum seated height (0.70mm). No PCB layout modifications are required.

Q: Which part should be specified for a new automotive design?

A: The ERJ-S1DF14R7U should be specified for new designs due to active product status. The ERJ-12SF14R7U is suitable only for legacy system support or when supply constraints necessitate substitution.
