Substitute Part Grouping Explanation

Substitution eligibility for the ERJ-S02F1873X is determined by strict equivalence across the following critical parameters:

• Resistance value: 187 kOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Power rating: 0.1W / 1/10W (exact match required)
• Package: 0402 (1005 Metric) (exact match required)
• Composition: Thick Film (exact match required)
• Temperature coefficient: ±200ppm/°C (exact match required)
• Operating temperature range: -55°C ~ 155°C (exact match required)
• Automotive qualification: AEC-Q200 (exact match required)
• RoHS compliance: ROHS3 Compliant (exact match required)

The ERJ-U02F1873X qualifies as a direct equivalent substitute based on identical electrical specifications, mechanical dimensions, and regulatory compliance across all parameters listed above.

Parameter Comparison

Engineering Selection Recommendations

Both ERJ-S02F1873X and ERJ-U02F1873X are active production components manufactured by Panasonic Electronic Components with identical electrical and mechanical specifications. Both parts maintain ROHS3 compliance and AEC-Q200 automotive qualification. The ERJ-U02F1873X offers higher inventory availability (2400 pieces versus 1089 pieces), making it suitable for high-volume production requirements. Selection between these parts should be based on supply chain availability and procurement lead times, as electrical performance and regulatory compliance are equivalent.

Frequently Asked Questions (FAQ)

Q: Can ERJ-U02F1873X be used as a direct replacement for ERJ-S02F1873X in automotive applications?

A: Yes. Both parts are AEC-Q200 qualified with identical resistance, tolerance, power rating, package dimensions, and operating temperature specifications. They are functionally and mechanically interchangeable.

Q: Are there any differences in the 0402 package dimensions between these parts?

A: No. Both parts share identical package specifications: 0.039" L x 0.020" W (1.00mm x 0.50mm) with maximum seated height of 0.016" (0.40mm). PCB layout and assembly processes require no modification.

Q: Do both parts meet the same environmental and compliance standards?

A: Yes. Both ERJ-S02F1873X and ERJ-U02F1873X are ROHS3 compliant, REACH unaffected, and carry MSL 1 (Unlimited) moisture sensitivity rating. They are suitable for identical application environments.

Q: What is the significance of the series designation change from ERJ-S02 to ERJ-U02?

A: The series designation reflects internal Panasonic product line categorization. The change does not affect electrical performance, mechanical compatibility, or regulatory compliance. Both series maintain identical specifications for the 187 kOhms ±1% 0402 resistor configuration.

Q: Which part should be selected for new designs?

A: Selection should be based on current inventory availability and supply chain requirements. Both parts are active production components with equivalent performance characteristics. The ERJ-U02F1873X currently offers higher stock levels (2400 pieces).
