• Mounting Type: Through Hole (exact match required)
• Package / Case: Radial, Can (exact match required)
• Operating Temperature Range: -40°C ~ 105°C (exact match required)

Allowable Variation Parameters:

• Voltage - Rated: May be equal to or greater than 6.3 V
• Lifetime @ Temperature: May be equal to or greater than 1000 Hrs @ 105°C
• Ripple Current: May be equal to or greater than specified values

The following parts meet all substitution criteria:

1. Rubycon 10ZLG100MEFC6.3X7 - Voltage upgrade to 10 V with enhanced ripple current performance
2. Rubycon 16ML100MEFC6.3X7 - Voltage upgrade to 16 V with extended lifetime (5000 Hrs @ 105°C)

Parameter Comparison

Engineering Selection Recommendations

Rubycon 10ZLG100MEFC6.3X7: This substitute provides a voltage rating upgrade from 6.3 V to 10 V while maintaining identical physical dimensions and lead spacing. The component offers significantly enhanced ripple current performance, particularly at high frequencies (480 mA @ 100 kHz versus 92.4 mA @ 10 kHz for the main part). Both components maintain 1000 Hrs @ 105°C lifetime specification and ROHS3 compliance. Height increases by 0.020" (0.50mm) to 0.335" (8.50mm), which may require PCB layout verification in space-constrained applications.

Rubycon 16ML100MEFC6.3X7: This substitute provides the highest voltage rating at 16 V with extended operational lifetime of 5000 Hrs @ 105°C, representing a five-fold improvement over the main part. Physical dimensions and lead spacing remain identical to the main part, with height maintained at 0.315" (8.00mm). This option is suitable for applications requiring maximum reliability and extended service life. ROHS3 compliance is maintained.

Both substitutes are ROHS3 compliant and REACH unaffected, meeting regulatory requirements equivalent to the main part.

Frequently Asked Questions (FAQ)

Q: Can the 10ZLG100MEFC6.3X7 be used as a direct replacement for the 6.3MH7100MEFC6.3X7?

A: Yes, the 10ZLG100MEFC6.3X7 is a direct substitute. All critical parameters match: 100 µF capacitance, ±20% tolerance, identical lead spacing (0.098" / 2.50mm), identical diameter (0.248" / 6.30mm), and identical operating temperature range (-40°C ~ 105°C). The height increases by 0.020" (0.50mm), which must be verified against PCB clearance requirements. The voltage rating upgrade from 6.3 V to 10 V provides enhanced safety margin in the circuit.

Q: Can the 16ML100MEFC6.3X7 be used as a direct replacement for the 6.3MH7100MEFC6.3X7?

A: Yes, the 16ML100MEFC6.3X7 is a direct substitute. All critical parameters match: 100 µF capacitance, ±20% tolerance, identical lead spacing (0.098" / 2.50mm), identical diameter (0.248" / 6.30mm), identical height (0.315" / 8.00mm), and identical operating temperature range (-40°C ~ 105°C). The voltage rating upgrade from 6.3 V to 16 V and extended lifetime (5000 Hrs @ 105°C) provide superior reliability characteristics.

Q: What is the difference between the two substitute parts?

A: The 10ZLG100MEFC6.3X7 offers a moderate voltage upgrade to 10 V with exceptional ripple current performance (480 mA @ 100 kHz). The 16ML100MEFC6.3X7 provides the highest voltage rating at 16 V with extended lifetime (5000 Hrs @ 105°C versus 1000 Hrs @ 105°C). The 10ZLG100MEFC6.3X7 is 0.020" (0.50mm) taller. Selection depends on circuit voltage requirements and desired operational lifetime.

Q: Are there any PCB layout considerations when substituting these parts?

A: The 10ZLG100MEFC6.3X7 has a maximum seated height of 0.335" (8.50mm) compared to 0.315" (8.00mm) for both the main part and the 16ML100MEFC6.3X7. Verify clearance above the component in space-constrained applications. Lead spacing remains constant at 0.098" (2.50mm) for all parts, so through-hole pad spacing requires no modification.

Q: Do all parts meet the same regulatory compliance standards?

A: Yes. The main part and both substitutes are ROHS3 compliant and REACH unaffected. All components carry the same regulatory classification (ECCN: EAR99, HTSUS: 8532.22.0020).

Q: Which substitute should I select for maximum reliability?

A: The 16ML100MEFC6.3X7 provides the highest reliability profile with extended lifetime of 5000 Hrs @ 105°C and the highest voltage rating of 16 V. This part is suitable for applications requiring maximum service life and operational margin.
