Substitute Part Grouping Explanation

Substitute parts for the MALSECL00AG368CARK are selected based on the following criteria:

Capacitance Match: 680 µF (exact match required)
Tolerance Match: ±20% (exact match required)
Voltage Rating: Equal to or greater than 10 V (higher voltage ratings provide design margin and are acceptable substitutes)
Package Compatibility: Radial, Can - SMD with identical surface mount land size (0.406" L x 0.406" W / 10.30 mm x 10.30 mm)
Mounting Type: Surface Mount (identical)
Compliance: ROHS3 Compliant, REACH Unaffected, MSL 1 (Unlimited)
Lifetime Rating: 2000 Hrs @ 105°C (minimum requirement)

Both substitute parts meet these criteria while offering higher voltage ratings (16 V and 25 V respectively), which provide additional safety margin in circuit applications.

Engineering Selection Recommendations

Both substitute parts are active products from established manufacturers, providing long-term availability and supply chain stability compared to the obsolete MALSECL00AG368CARK. Selection between the two substitutes depends on circuit voltage requirements and physical space constraints:

687AXZ016M offers a 16 V rating with extended low-temperature operation (-55°C minimum), suitable for applications requiring moderate voltage margin and cold-temperature performance.

687SVH025MGE provides a 25 V rating with improved ripple current handling (490 mA @ 120 Hz) and lower ESR (390 mOhm @ 120 Hz), appropriate for applications requiring higher voltage headroom and enhanced thermal performance.

Both parts maintain ROHS3 compliance, MSL 1 rating, and identical surface mount land patterns, ensuring direct PCB compatibility. Height differences (10.60 mm and 10.80 mm respectively versus 10.50 mm original) are within typical assembly tolerances for surface mount radial can packages.

Frequently Asked Questions (FAQ)

Q: Can 687AXZ016M or 687SVH025MGE be used as direct replacements for MALSECL00AG368CARK?

A: Yes. Both parts share identical capacitance (680 µF), tolerance (±20%), package type (Radial, Can - SMD), surface mount land size (10.30 mm x 10.30 mm), and lifetime rating (2000 Hrs @ 105°C). Higher voltage ratings provide additional design margin without affecting circuit function in applications originally rated for 10 V.

Q: What is the impact of higher voltage ratings on circuit performance?

A: Higher voltage-rated capacitors (16 V and 25 V) are electrically compatible with 10 V circuits. They provide increased safety margin and typically exhibit improved reliability. No circuit modifications are required.

Q: Are there physical space considerations when substituting these parts?

A: Case diameter remains constant at 10.00 mm. Height increases slightly: 687AXZ016M measures 10.60 mm (versus 10.50 mm original) and 687SVH025MGE measures 10.80 mm. These differences are within standard surface mount assembly tolerances and do not typically require PCB redesign.

Q: How do ESR values compare across these parts?

A: The original part specifies 90 mOhm @ 100 kHz. Substitute parts specify ESR @ 120 Hz: 687AXZ016M at 488 mOhm and 687SVH025MGE at 390 mOhm. These measurements are taken at different frequencies; direct comparison requires normalization to identical test conditions. Both substitutes meet the 2000-hour lifetime requirement at 105°C.

Q: Are both substitutes suitable for bypass and decoupling applications?

A: 687SVH025MGE is explicitly rated for bypass and decoupling applications. 687AXZ016M is rated for general-purpose use. Application suitability depends on specific circuit requirements and frequency response characteristics.

Q: What is the availability status of these substitute parts?

A: 687AXZ016M and 687SVH025MGE are both active products with current inventory (936 and 994 units respectively), ensuring long-term supply availability compared to the obsolete MALSECL00AG368CARK.
