Substitute Part Grouping Explanation

Substitution eligibility for the ERJ-S14F4531U is determined by strict equivalence across the following critical parameters:

• Resistance value: 4.53 kOhms
• Tolerance: ±1%
• Power rating: 0.5W (1/2W)
• Package format: 1210 (3225 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C
• Automotive qualification: AEC-Q200
• Physical dimensions: 0.126" L x 0.098" W (3.20mm x 2.50mm)
• Height - Seated (Max): 0.028" (0.70mm)
• Termination count: 2
• RoHS compliance: ROHS3 Compliant
• Moisture sensitivity: MSL 1 (Unlimited)

The ERJ-P14F4531U meets all these criteria and qualifies as a direct substitute. The primary distinction between the main part and substitute is the feature set: the ERJ-S14F4531U includes anti-sulfur coating, while the ERJ-P14F4531U features pulse withstanding capability. Both maintain identical electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

Both the ERJ-S14F4531U and ERJ-P14F4531U are active production components from Panasonic Electronic Components with full AEC-Q200 automotive qualification and ROHS3 compliance. Selection between these parts depends on application-specific requirements:

The ERJ-S14F4531U is appropriate for applications requiring anti-sulfur protection in corrosive environments. The ERJ-P14F4531U is suitable for applications requiring pulse withstanding capability. Both parts maintain identical electrical performance, mechanical fit, and regulatory compliance across all specified parameters. Inventory availability should be considered: ERJ-P14F4531U has 3558 units in stock compared to 867 units for ERJ-S14F4531U.

Frequently Asked Questions (FAQ)

Q: Can ERJ-P14F4531U replace ERJ-S14F4531U in all applications?

A: Yes, from an electrical and mechanical standpoint. Both parts share identical resistance, tolerance, power rating, package dimensions, temperature coefficient, and operating temperature range. The functional difference is feature-based: anti-sulfur coating versus pulse withstanding capability. Application requirements determine which feature set is necessary.

Q: Are the physical dimensions identical?

A: Yes. Both parts use the 1210 (3225 Metric) package with dimensions of 0.126" L x 0.098" W (3.20mm x 2.50mm) and maximum seated height of 0.028" (0.70mm). PCB layout and assembly processes remain unchanged.

Q: Do both parts meet automotive standards?

A: Yes. Both ERJ-S14F4531U and ERJ-P14F4531U carry AEC-Q200 automotive qualification and are ROHS3 compliant. Both are suitable for automotive applications within the specified operating temperature range of -55°C ~ 155°C.

Q: What is the difference in moisture sensitivity?

A: Both parts have Moisture Sensitivity Level (MSL) 1, which indicates unlimited shelf life without moisture control requirements.

Q: Which part should be selected for cost optimization?

A: Selection should be based on application requirements rather than cost alone. The ERJ-P14F4531U has higher inventory availability (3558 units versus 867 units), which may provide supply chain advantages. Verify that the pulse withstanding feature of ERJ-P14F4531U or anti-sulfur feature of ERJ-S14F4531U aligns with your circuit design requirements.
