• Matching tolerance: ±1%
• Equivalent power rating: 0.75W (3/4W)
• Same package designation: 2010 (5025 Metric)
• Identical physical dimensions: 0.197" L x 0.098" W (5.00mm x 2.50mm), Height 0.028" (0.70mm) maximum
• Matching composition: Thick Film
• Equivalent temperature coefficient: ±100ppm/°C
• Same operating temperature range: -55°C ~ 155°C
• Automotive qualification: AEC-Q200
• Equivalent compliance: ROHS3 Compliant, REACH Unaffected, MSL 1

All substitute parts meet these criteria and are suitable for direct replacement in applications where the ERJ-S1DF2430U is specified.

Parameter Comparison

Engineering Selection Recommendations

All three parts—ERJ-S1DF2430U, CRCW2010243RFKEF, and RMCF2010FT243R—are active production components with identical electrical and mechanical specifications. Each part carries AEC-Q200 automotive qualification and ROHS3 compliance, confirming suitability for automotive and industrial applications.

Selection between these parts may be based on:

• Supplier availability and lead time
• Inventory levels (Panasonic: 814 units; Vishay Dale: 5088 units; Stackpole: 8927 units)
• Established supply chain relationships
• Cost considerations within equivalent specifications

All parts are interchangeable from an engineering standpoint when the specified parameters are required.

Frequently Asked Questions (FAQ)

Q: Can CRCW2010243RFKEF replace ERJ-S1DF2430U in automotive applications?

A: Yes. Both parts meet AEC-Q200 automotive qualification, share identical electrical specifications (243 Ohms ±1%, 0.75W), and are housed in the same 2010 (5025 Metric) package with matching physical dimensions and temperature performance.

Q: Are there differences in the anti-sulfur coating between these parts?

A: The ERJ-S1DF2430U is specified with anti-sulfur coating. The CRCW2010243RFKEF and RMCF2010FT243R specifications provided do not explicitly list anti-sulfur features. Verify coating requirements with the specific application before substitution.

Q: Do all three parts have the same moisture sensitivity level?

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

Q: Can these parts be used interchangeably in PCB assembly?

A: Yes. All parts share identical package designation (2010), physical dimensions (0.197" L x 0.098" W, 0.028" height maximum), and termination count (2). They are compatible with the same PCB footprints and assembly processes.

Q: What is the temperature coefficient significance for these resistors?

A: All three parts have a temperature coefficient of ±100ppm/°C and operate across -55°C to 155°C. This ensures consistent resistance stability across the full automotive temperature range.

Q: Are all parts RoHS and REACH compliant?

A: Yes. All three parts are ROHS3 Compliant and REACH Unaffected, meeting environmental and regulatory requirements for automotive and industrial markets.
