Substitute Part Grouping Explanation

Substitute parts for the ALS71H134NF063 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: 130000 µF
• Voltage Rating: 63 V
• Tolerance: ±20%
• ESR @ 100Hz: 9 mOhm
• Lifetime @ 85°C: 20000 Hrs
• Operating Temperature Range: -40°C ~ 85°C
• Ripple Current @ 100 Hz: 27.3 A
• Ripple Current @ 10 kHz: 28.9 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): 4.213" (107.00mm)
• Lead Spacing: 1.252" (31.80mm)

Compliance & Certification (Must Match):

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

The ALS70A134NF063 meets all these criteria and is classified as a parametric equivalent substitute.

Parameter Comparison

Engineering Selection Recommendations

Both the ALS71H134NF063 and ALS70A134NF063 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, including capacitance, voltage rating, ESR, ripple current ratings, thermal characteristics, and physical dimensions.

Selection between these parts should be based on:

1. Availability: The ALS70A134NF063 has higher inventory (1017 Pcs) compared to the ALS71H134NF063 (723 Pcs).

2. Series Designation: The ALS71H134NF063 belongs to the ALS71 series, while the ALS70A134NF063 belongs to the ALS70 series. Both series are current KEMET product lines with equivalent performance specifications.

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

4. Application Compatibility: Direct substitution is supported for all general-purpose applications requiring 130000 µF, 63 V aluminum electrolytic capacitors with screw terminal connections and chassis mount configuration.

Frequently Asked Questions (FAQ)

Q: Can the ALS70A134NF063 be used as a direct replacement for the ALS71H134NF063?

A: Yes. The ALS70A134NF063 is a parametric equivalent substitute. All electrical parameters (capacitance, voltage, ESR, ripple current, lifetime, temperature range) and mechanical parameters (package type, dimensions, lead spacing, mounting configuration) are identical. Both parts are ROHS3 compliant and REACH unaffected.

Q: What are the key parameters that determine substitutability?

A: Substitutability is determined by exact matching of: capacitance (130000 µF), voltage rating (63 V), tolerance (±20%), ESR @ 100Hz (9 mOhm), lifetime @ 85°C (20000 Hrs), operating temperature range (-40°C ~ 85°C), ripple current specifications (27.3 A @ 100 Hz, 28.9 A @ 10 kHz), package type (Radial, Can - Screw Terminals), mounting type (Chassis Mount), and physical dimensions (3.031" Dia, 4.213" height, 1.252" lead spacing).

Q: Are there any differences in the series designation between ALS71H and ALS70A?

A: The series designation differs (ALS71 versus ALS70), but this reflects internal KEMET product line organization. All specified electrical and mechanical parameters are identical, and both series are Active products with current manufacturing status.

Q: What is the lead spacing and how does it affect installation?

A: The lead spacing is 1.252" (31.80mm) for both parts. This measurement defines the distance between screw terminals and must match the PCB or chassis mounting holes. Both substitute parts have identical lead spacing, ensuring compatible installation.

Q: Are both parts suitable for high-ripple-current applications?

A: Yes. Both parts are rated for 27.3 A ripple current at 100 Hz and 28.9 A ripple current at 10 kHz, with an ESR of 9 mOhm @ 100Hz. These specifications support applications requiring sustained ripple current handling.

Q: What is the physical footprint, and can these parts fit in existing designs?

A: Both parts have identical dimensions: 3.031" diameter (77.00mm) and 4.213" maximum seated height (107.00mm). They are designed for chassis mount applications with screw terminal connections. The physical footprint is identical between the main part and substitute.

Q: Do both parts have the same moisture sensitivity rating?

A: Yes. Both the ALS71H134NF063 and ALS70A134NF063 have Moisture Sensitivity Level (MSL) 1, which indicates unlimited shelf life without moisture control requirements.

Q: What compliance certifications apply to both parts?

A: Both parts are ROHS3 compliant and REACH unaffected. They meet current regulatory requirements for electronic component manufacturing and distribution.
