Substitute Part Grouping Explanation

Substitute parts for the ALS71P623NP100 are identified based on strict equivalence across all critical electrical and mechanical parameters. The substitution logic is based on the following criteria:

Electrical Parameters (Must Match Exactly):

• Capacitance: 62000 µF
• Voltage Rating: 100 V
• Tolerance: ±20%
• ESR @ 100Hz: 11 mOhm
• Lifetime @ 85°C: 20000 Hrs
• Operating Temperature Range: -40°C ~ 85°C
• Ripple Current @ 100 Hz: 28.9 A
• Ripple Current @ 10 kHz: 31.2 A

Mechanical Parameters (Must Match Exactly):

• Package / Case: Radial, Can - Screw Terminals
• Mounting Type: Chassis Mount
• Size / Dimension: 3.031" Dia (77.00mm)
• Height - Seated (Max): 5.827" (148.00mm)
• Lead Spacing: 1.252" (31.80mm)

Compliance & Certifications (Must Match):

• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)
• REACH Status: REACH Unaffected

The ALS70A623NP100 meets all these criteria and is classified as a parametric equivalent substitute.

Parameter Comparison

Engineering Selection Recommendations

Both the ALS71P623NP100 and ALS70A623NP100 are Active products manufactured by KEMET with full ROHS3 compliance and REACH unaffected status. The parts are electrically and mechanically identical across all specified parameters. Selection between these two parts should be based on:

1. Inventory Availability: The ALS71P623NP100 has 1116 units in stock, while the ALS70A623NP100 has 1026 units available.

2. Series Designation: The ALS71P623NP100 belongs to the ALS71 series, while the ALS70A623NP100 belongs to the ALS70 series. Both series are current KEMET product lines.

3. Compliance Certifications: Both parts meet identical regulatory requirements (ROHS3, REACH unaffected, MSL 1).

4. Application Compatibility: For general-purpose applications requiring 62000 µF at 100 V with the specified thermal and ripple current characteristics, either part is suitable for direct substitution.

Frequently Asked Questions (FAQ)

Q: Can the ALS70A623NP100 be used as a direct replacement for the ALS71P623NP100?

A: Yes. The ALS70A623NP100 is a parametric equivalent substitute. All electrical parameters (capacitance, voltage, ESR, ripple current, lifetime), mechanical dimensions, and compliance certifications are identical.

Q: Are there any differences in the screw terminal specifications between these parts?
