Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ERJ-S1DF4530U are qualified based on strict equivalence across the following parameters:

• Resistance value: 453 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
• Automotive compliance: AEC-Q200
• RoHS compliance: ROHS3
• Moisture sensitivity: MSL 1

All identified substitutes maintain identical electrical performance, mechanical fit, and regulatory compliance. Substitution is valid across manufacturers when these parameters are matched.

Parameter Comparison

Engineering Selection Recommendations

All three parts—ERJ-S1DF4530U, CRCW2010453RFKEF, and RMCF2010FT453R—are active products with identical electrical and mechanical specifications. Selection among these substitutes may be based on inventory availability, supply chain considerations, or manufacturer preference. The Panasonic ERJ-S1DF4530U includes anti-sulfur coating as an additional feature; however, all parts meet AEC-Q200 automotive qualification and ROHS3 compliance requirements. No technical performance differentiation exists between these options for standard circuit applications.

Frequently Asked Questions (FAQ)

Q: Can CRCW2010453RFKEF replace ERJ-S1DF4530U in automotive applications?

A: Yes. Both parts are AEC-Q200 rated with identical resistance, tolerance, power rating, package dimensions, and operating temperature range. Direct substitution is valid for automotive circuits.

Q: Are there differences in the anti-sulfur feature between ERJ-S1DF4530U and CRCW2010453RFKEF?

A: The ERJ-S1DF4530U specifies anti-sulfur coating. CRCW2010453RFKEF does not list this feature in provided specifications. For applications requiring anti-sulfur protection, verify with the manufacturer or retain the Panasonic part.

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

A: The 2010 package (5025 Metric) defines the physical dimensions: 0.197" L x 0.098" W (5.00mm x 2.50mm) with maximum seated height of 0.028" (0.70mm). All three substitutes share identical package specifications, ensuring PCB footprint compatibility.

Q: Do all substitutes have the same moisture sensitivity rating?

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

Q: Can these parts be used interchangeably in tape and reel packaging?

A: Yes. All three parts are supplied in Tape & Reel (TR) packaging format, compatible with standard pick-and-place assembly equipment.
