Substitute Part Grouping Explanation

Substitute parts for the ALS70C164NP063 are identified based on strict parametric equivalence. The substitution logic is based on the following critical parameters that must remain identical:

• Capacitance Value: 160000 µF (exact match required)
• Rated Voltage: 63 V (exact match required)
• Tolerance: ±20% (exact match required)
• ESR @ 100Hz: 8 mOhm (exact match required)
• Lifetime @ 85°C: 20000 Hrs (exact match required)
• Operating Temperature Range: -40°C to 85°C (exact match required)
• Ripple Current Ratings: 30.6 A @ 100 Hz and 32.2 A @ 10 kHz (exact match required)
• Package / Case: Radial, Can - Screw Terminals (exact match required)
• Mounting Type: Chassis Mount (exact match required)
• Physical Dimensions: 3.031" Dia (77.00mm), Height 5.827" (148.00mm), Lead Spacing 1.252" (31.80mm) (exact match required)

The ALS70A164NP063 qualifies as a parametric equivalent substitute because it maintains all critical electrical and mechanical specifications identical to the main part.

Frequently Asked Questions (FAQ)

Q: Can ALS70A164NP063 be used as a direct replacement for ALS70C164NP063?

A: Yes. The ALS70A164NP063 is a parametric equivalent substitute. All electrical specifications (capacitance, voltage rating, ESR, ripple current, lifetime) and mechanical specifications (package type, dimensions, lead spacing, mounting configuration) are identical. No circuit design changes are required.

Q: What is the difference between the ALS70C and ALS70A base product numbers?

A: The base product numbers (ALS70C versus ALS70A) indicate different product lines within the ALS70 series. However, for the 160000 µF, 63 V configuration with ±20% tolerance, both variants maintain identical electrical and mechanical specifications.

Q: Are there any compliance or certification differences between these parts?

A: No. Both parts carry identical compliance certifications: RoHS3 Compliant, REACH Unaffected, MSL 1 (Unlimited), ECCN EAR99, and HTSUS 8532.22.0085.

Q: Can these capacitors be used in high-ripple-current applications?

A: Yes. Both parts are rated for 30.6 A ripple current at 100 Hz and 32.2 A ripple current at 10 kHz. The 8 mOhm ESR @ 100Hz supports these ripple current specifications across the operating temperature range of -40°C to 85°C.

Q: What is the expected operational lifetime of these capacitors?

A: Both parts are rated for 20000 hours of operation at 85°C. Operational lifetime extends beyond this rating at lower operating temperatures in accordance with standard aluminum electrolytic capacitor aging characteristics.

Q: Are these parts suitable for chassis-mounted applications?

A: Yes. Both parts are specified for Chassis Mount configuration with screw terminals. The 3.031" diameter (77.00mm) can and 5.827" maximum seated height (148.00mm) accommodate standard chassis mounting hardware. Lead spacing of 1.252" (31.80mm) supports standard PCB or chassis terminal configurations.

Q: What is the polarization requirement for these capacitors?

A: Both parts are polar capacitors. Correct polarity must be observed during installation. The positive and negative terminals must be connected according to circuit polarity requirements.
