Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ERJ-S14F4703U is determined by strict alignment of the following parameters:

• Resistance value: 470 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
• Number of terminations: 2
• RoHS compliance: ROHS3 Compliant
• Moisture sensitivity level: 1 (Unlimited)

The RC1210FR-07470KL from YAGEO meets all these electrical and mechanical criteria, making it a direct functional equivalent for the ERJ-S14F4703U.

Parameter Comparison

Engineering Selection Recommendations

Both the ERJ-S14F4703U and RC1210FR-07470KL are ROHS3 compliant and maintain identical electrical specifications across resistance, tolerance, power rating, and temperature coefficient. The ERJ-S14F4703U carries AEC-Q200 automotive qualification with anti-sulfur protection, while the RC1210FR-07470KL features moisture-resistant construction. Both components operate across the -55°C to 155°C temperature range with MSL 1 rating. Physical dimensions show minor variations within the 1210 package specification, with the YAGEO component exhibiting slightly reduced height. Selection between these parts should be based on specific application requirements regarding automotive qualification or moisture resistance features.

Frequently Asked Questions (FAQ)

Q: Can RC1210FR-07470KL replace ERJ-S14F4703U in automotive applications?

A: Both components share identical electrical specifications and ROHS3 compliance. The ERJ-S14F4703U carries explicit AEC-Q200 automotive qualification. Application requirements should determine whether this certification is mandatory.

Q: Are there dimensional compatibility concerns between these parts?
