Key Parameters

Substitute Part Grouping Explanation

Substitution of the 158TTA025M is determined by strict equivalence across the following parameters:

Primary Equivalence Criteria:

• Capacitance value: 1500 µF (exact match required)
• Rated voltage: 25 V (exact match required)
• Tolerance: ±20% (exact match required)
• Polarization: Polar (exact match required)
• Package type: Axial, Can (exact match required)
• Mounting type: Through Hole (exact match required)
• Operating temperature range: -40°C ~ 85°C (minimum requirement)

Secondary Compatibility Parameters:

• RoHS compliance status (ROHS3 Compliant)
• REACH compliance status (REACH Unaffected)
• Moisture Sensitivity Level (MSL 1 or Not Applicable acceptable)

The substitute part MAL202116152E3 meets all primary equivalence criteria and secondary compatibility requirements. Dimensional variations within the axial, can package format are acceptable provided the component fits the intended PCB layout and mechanical assembly constraints.

Parameter Comparison

Engineering Selection Recommendations

Both the 158TTA025M and MAL202116152E3 are Active product status components with full ROHS3 compliance and REACH unaffected status, qualifying them for use in regulated electronic assemblies. The substitute part MAL202116152E3 demonstrates superior performance characteristics in ESR (179 mOhm versus 198.9 mOhm) and extended lifetime rating (8000 Hrs @ 85°C versus 2000 Hrs @ 85°C), making it functionally interchangeable for general-purpose applications.

Selection between these parts should be based on:

1. Availability and lead time - Both parts are in stock; inventory levels differ (817 Pcs for 158TTA025M; 1379 Pcs for MAL202116152E3)
2. PCB layout constraints - Dimensional differences (diameter 13.00mm vs 12.50mm; length 26.00mm vs 30.00mm) must be verified against available board space
3. Procurement cost - Evaluate unit pricing and volume discounts from respective suppliers
4. Supply chain strategy - Multi-source qualification reduces single-supplier dependency

Both parts satisfy all mandatory electrical and mechanical substitution criteria for general-purpose aluminum electrolytic capacitor applications.

Frequently Asked Questions (FAQ)

Q: Can MAL202116152E3 be used as a direct replacement for 158TTA025M?

A: Yes. Both parts are electrically equivalent with identical capacitance (1500 µF), rated voltage (25 V), tolerance (±20%), polarization (Polar), and operating temperature range (-40°C ~ 85°C). Both are through-hole mounted in axial, can packages and meet ROHS3 and REACH compliance requirements.

Q: What are the dimensional differences between these parts?

A: The 158TTA025M measures 0.512" diameter × 1.024" length (13.00mm × 26.00mm). The MAL202116152E3 measures 0.492" diameter × 1.181" length (12.50mm × 30.00mm). The substitute is slightly narrower but longer. PCB layout verification is required to confirm fit within available mounting space.

Q: Does the lower ESR of MAL202116152E3 affect compatibility?

A: No. Lower ESR (179 mOhm versus 198.9 mOhm) is a performance advantage, reducing heat generation and improving ripple current handling. This does not compromise substitution compatibility.

Q: Why does MAL202116152E3 have a longer lifetime rating?

A: The MAL202116152E3 is rated for 8000 Hrs @ 85°C compared to 2000 Hrs @ 85°C for the 158TTA025M. This reflects different manufacturing processes and internal design. Both ratings satisfy general-purpose application requirements; the extended rating provides additional margin.

Q: Are there any moisture sensitivity concerns?

A: The 158TTA025M has MSL 1 (Unlimited). The MAL202116152E3 is listed as Not Applicable for MSL. Both are suitable for standard handling and storage without special moisture control measures.

Q: What compliance certifications apply to both parts?

A: Both parts are ROHS3 compliant and REACH unaffected. Both carry ECCN EAR99 classification and HTSUS code 8532.22.0020, confirming regulatory equivalence for international trade and assembly use.
