Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by the following criteria:

Direct Substitutes maintain identical or equivalent electrical and mechanical specifications:

• Capacitance: 330 µF (±20% tolerance)
• Voltage Rating: 10 V minimum
• Physical dimensions: 0.315" diameter (8.00mm), compatible height range
• Surface mount land size: 0.327" L x 0.327" W (8.30mm x 8.30mm)
• Operating temperature range: -40°C ~ 125°C
• Lifetime rating: 2000 Hrs @ 125°C
• Polarization: Polar
• AEC-Q200 automotive qualification
• RoHS3 compliance

Upgrade Substitutes exceed the original voltage rating while maintaining all other critical parameters, providing enhanced voltage margin:

• Capacitance: 330 µF (±20% tolerance)
• Voltage Rating: 16 V (exceeds 10 V requirement)
• Physical dimensions and land size compatibility maintained
• All compliance and qualification requirements met

Parameter Comparison

Engineering Selection Recommendations

EEE-TG1A331UP (Panasonic) functions as a direct substitute for EMHJ100ARA331MHA0G. Both parts maintain identical capacitance, voltage rating, physical dimensions, and land size specifications. Both carry AEC-Q200 automotive qualification and ROHS3 compliance. The primary difference is ESR at 100 kHz (500 mOhm versus 150 mOhm), which reflects manufacturer design variation within the same product category. This part is suitable for applications where the original Chemi-Con part is unavailable.

EDT337M016S9MAA (KEMET) functions as an upgrade substitute. The 16 V voltage rating exceeds the 10 V requirement of the original specification, providing additional voltage margin in the circuit. Physical dimensions, land size, and all compliance certifications remain compatible. This part is suitable for applications requiring enhanced voltage headroom or where the higher voltage rating provides system-level benefits. The height dimension (10.50mm) is within acceptable tolerance for surface mount assembly.

All three parts are active in production, carry AEC-Q200 automotive qualification, and comply with ROHS3 and REACH requirements. Selection between direct and upgrade substitutes depends on circuit voltage requirements and design margin considerations.

Frequently Asked Questions (FAQ)

Q: Can EEE-TG1A331UP replace EMHJ100ARA331MHA0G in automotive applications?

A: Yes. Both parts carry AEC-Q200 qualification, maintain 330 µF capacitance at ±20% tolerance, 10 V voltage rating, identical physical dimensions (8.00mm diameter), and compatible surface mount land sizes (8.30mm x 8.30mm). Both support -40°C to 125°C operating temperature and 2000 Hrs @ 125°C lifetime rating. Direct substitution is supported.

Q: What is the difference between a direct substitute and an upgrade substitute?

A: A direct substitute (EEE-TG1A331UP) maintains all electrical and mechanical specifications of the original part. An upgrade substitute (EDT337M016S9MAA) exceeds one or more specifications—in this case, the voltage rating is increased from 10 V to 16 V—while maintaining all other critical parameters. Upgrade substitutes provide enhanced performance margins.

Q: Are there packaging differences between these parts?

A: Yes. EMHJ100ARA331MHA0G and EDT337M016S9MAA are supplied in Tape & Reel (TR) packaging. EEE-TG1A331UP is supplied in Cut Tape (CT) & Digi-Reel® packaging. Packaging format does not affect electrical or mechanical compatibility; it reflects supply chain and assembly process preferences.

Q: Does the higher ESR of EEE-TG1A331UP affect circuit performance?

A: ESR differences (150 mOhm versus 500 mOhm @ 100 kHz) reflect manufacturer design variation. Circuit impact depends on ripple current requirements and thermal management. EMHJ100ARA331MHA0G specifies 350 mA @ 100 kHz ripple current; EEE-TG1A331UP specifies 197 mA @ 100 kHz. Application-specific ripple current requirements determine suitability.

Q: Can EDT337M016S9MAA be used in place of EMHJ100ARA331MHA0G?

A: Yes. EDT337M016S9MAA is an upgrade substitute with 16 V rating versus the original 10 V rating. All physical dimensions, land sizes, operating temperature range, lifetime rating, and compliance certifications are compatible. The higher voltage rating provides additional circuit margin.

Q: Are all three parts RoHS3 compliant?

A: Yes. EMHJ100ARA331MHA0G, EEE-TG1A331UP, and EDT337M016S9MAA are all ROHS3 compliant and REACH unaffected. All three carry MSL 1 (Unlimited) moisture sensitivity rating.

Q: What is the maximum seated height for each part?

A: EMHJ100ARA331MHA0G: 0.406" (10.30mm); EEE-TG1A331UP: 0.402" (10.20mm); EDT337M016S9MAA: 0.413" (10.50mm). All heights are within acceptable tolerance for standard surface mount assembly processes.
