Key Parameters

Substitute Part Grouping Explanation

Substitution of the QAP2G155KRP is determined by the following critical parameters:

• Capacitance Value: Must be 1.5 µF (exact match required)
• Dielectric Material: Polypropylene (PP), Metallized (maintains electrical characteristics)
• Mounting Type: Through Hole (physical compatibility)
• Package / Case: Axial (form factor compatibility)
• Termination: PC Pins (connection compatibility)
• Operating Temperature Range: -40°C ~ 85°C (functional envelope)
• Voltage Rating - DC: Minimum 400V (equal or higher acceptable)
• RoHS Compliance: ROHS3 Compliant (regulatory requirement)

The substitute part C4GAMUD4150AA1J meets all critical substitution criteria. It maintains identical capacitance, dielectric material, mounting configuration, and temperature range. The substitute provides enhanced voltage rating (850V DC) and improved tolerance (±5%), representing a direct functional upgrade while maintaining physical and electrical compatibility.

Parameter Comparison

Engineering Selection Recommendations

The C4GAMUD4150AA1J from KEMET is a direct functional equivalent for the obsolete QAP2G155KRP. Both components are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements.

Frequently Asked Questions (FAQ)

Q: Can the C4GAMUD4150AA1J replace the QAP2G155KRP in existing applications?

A: Yes. Both components share identical capacitance (1.5 µF), dielectric material (polypropylene metallized), operating temperature range (-40°C to 85°C), and axial through-hole configuration. The substitute's higher voltage rating (850V) and tighter tolerance (±5%) are compatible with all applications designed for the original part.

Q: What are the physical dimension differences between these parts?

A: The QAP2G155KRP measures 0.909" W × 0.528" T × 1.378" L (23.10mm × 13.40mm × 35.00mm). The C4GAMUD4150AA1J measures 0.965" Dia × 1.732" L (24.50mm × 44.00mm). Both are axial through-hole components; verify PCB layout clearance for the slightly larger substitute dimensions.

Q: Are both parts RoHS compliant?

A: Yes. Both the QAP2G155KRP and C4GAMUD4150AA1J are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards.

Q: What is the tolerance difference and does it matter?

A: The QAP2G155KRP has ±10% tolerance while the C4GAMUD4150AA1J has ±5% tolerance. The tighter tolerance of the substitute represents improved capacitance accuracy and does not create compatibility issues in applications designed for the original part.

Q: Is the substitute part currently available?

A: Yes. The C4GAMUD4150AA1J is in active production status with 1271 pcs confirmed in stock, providing reliable supply availability compared to the obsolete QAP2G155KRP.
