Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ERJ-S1DF2370U are qualified based on the following criteria:

Electrical Parameters: Resistance value (237 Ohms), tolerance (±1%), and power rating (0.75W) must be identical.

Mechanical Parameters: Package designation (2010 / 5025 Metric) and physical dimensions (0.197" L x 0.098" W / 5.00mm x 2.50mm) must match exactly.

Environmental & Compliance Parameters: Temperature coefficient (±100ppm/°C), operating temperature range (-55°C ~ 155°C), AEC-Q200 automotive qualification, ROHS3 compliance, and MSL 1 rating must be maintained.

Composition: Thick film construction is required for all substitutes.

All identified substitute parts meet these criteria and are suitable for direct replacement in automotive and industrial applications requiring AEC-Q200 qualification.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection: ERJ-S1DF2370U remains the recommended choice for new designs due to its active product status and anti-sulfur feature specification.

Alternative Selections: CRCW2010237RFKEF (Vishay Dale) and RMCF2010FT237R (Stackpole Electronics Inc) are both active products with identical electrical and mechanical specifications. Both are suitable for direct substitution in applications requiring AEC-Q200 automotive qualification and ROHS3 compliance.

Legacy Designs: ERJ-12SF2370U (Panasonic) is marked as "Not For New Designs" and should only be used in existing production where design continuity is required. This part remains functionally equivalent but is not recommended for new circuit implementations.

All substitute parts maintain full compliance with automotive AEC-Q200 standards, ROHS3 directives, and MSL 1 moisture sensitivity requirements.

Frequently Asked Questions (FAQ)

Q: Can ERJ-12SF2370U be used as a direct replacement for ERJ-S1DF2370U?

A: Yes, ERJ-12SF2370U is electrically and mechanically equivalent. However, it is marked "Not For New Designs." Use only in existing production or legacy applications where design continuity is required.

Q: Are Vishay Dale CRCW2010237RFKEF and Stackpole RMCF2010FT237R suitable for automotive applications?

A: Yes. Both parts carry AEC-Q200 automotive qualification, ROHS3 compliance, and identical electrical specifications (237 Ohms ±1%, 0.75W). Both are active products suitable for new designs.

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

A: The 2010 package (5025 Metric) specifies the physical dimensions: 0.197" L x 0.098" W (5.00mm x 2.50mm). All substitute parts use this identical package, ensuring PCB footprint compatibility.

Q: Do all substitute parts have the same temperature coefficient?

A: Yes. All parts listed have a temperature coefficient of ±100ppm/°C and operate across the identical temperature range of -55°C ~ 155°C.

Q: What does MSL 1 (Unlimited) mean for moisture sensitivity?

A: MSL 1 indicates the lowest moisture sensitivity level, meaning the component has unlimited shelf life under normal storage conditions and requires no special moisture control during handling or assembly.

Q: Are there any differences in the anti-sulfur feature among these parts?

A: The ERJ-S1DF2370U explicitly specifies anti-sulfur coating. The substitute parts do not list this feature in their specifications. For applications requiring anti-sulfur protection, ERJ-S1DF2370U is the specified choice.
