Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ERJ-S1DF18R7U is determined by strict equivalence across the following parameters:

• Resistance value: 18.7 Ohms
• Tolerance: ±1%
• Power rating: 0.75W
• Package: 2010 (5025 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C
• AEC-Q200 automotive qualification
• RoHS3 compliance
• MSL rating: 1 (Unlimited)

All identified substitute parts meet these criteria. Substitution is valid across manufacturers when all electrical and mechanical parameters remain identical. Product status (Active or Not For New Designs) does not affect functional equivalence but may influence long-term availability considerations.

Parameter Comparison

Engineering Selection Recommendations

All three parts listed are functionally equivalent and meet identical electrical and mechanical specifications. Selection should be based on the following factors:

ERJ-S1DF18R7U (Panasonic): Primary choice for new designs. Active product status ensures long-term availability and manufacturer support. Anti-sulfur coating provides additional environmental protection.

ERJ-12SF18R7U (Panasonic): Functionally equivalent but marked as Not For New Designs. This designation indicates the manufacturer is transitioning away from this series. Use only for legacy system maintenance or when existing inventory must be maintained. Higher inventory availability (5916 pieces) may support short-term requirements.

RMCF2010FT18R7 (Stackpole Electronics): Active product status with full AEC-Q200 qualification. Suitable for new designs as an alternative manufacturer source. Provides supply chain diversification and maintains equivalent performance characteristics.

Frequently Asked Questions (FAQ)

Q: Can ERJ-12SF18R7U be used in place of ERJ-S1DF18R7U?

A: Yes. Both parts are electrically and mechanically identical with matching resistance, tolerance, power rating, package, temperature coefficient, and operating range. The ERJ-12SF18R7U is marked Not For New Designs, indicating Panasonic is phasing out this series. For new designs, ERJ-S1DF18R7U is the recommended choice.

Q: Is RMCF2010FT18R7 a direct substitute?

A: Yes. The Stackpole RMCF2010FT18R7 meets all electrical and mechanical specifications of the ERJ-S1DF18R7U. Both are Active products with AEC-Q200 qualification. Cross-manufacturer substitution is valid when all parameters match.

Q: What is the significance of the 2010 package designation?

A: The 2010 package (5025 Metric) is the physical footprint and size specification. All three parts use this identical package, ensuring PCB layout compatibility and interchangeability without redesign.

Q: Does the anti-sulfur feature of ERJ-S1DF18R7U affect substitution?

A: The anti-sulfur coating is a feature of the ERJ-S1DF18R7U. The ERJ-12SF18R7U and RMCF2010FT18R7 do not list this feature in their specifications. For applications requiring anti-sulfur protection, ERJ-S1DF18R7U is the specified choice.

Q: Are all parts RoHS3 compliant?

A: Yes. All three parts are ROHS3 Compliant and meet environmental compliance requirements for EU and global markets.

Q: What is MSL 1 (Unlimited)?

A: Moisture Sensitivity Level 1 indicates the component has unlimited shelf life and requires no special moisture control during storage or handling. All three parts carry this rating.
