Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SLP392M050A7P3 is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Requirements:

• Capacitance value: 3900 µF (exact match)
• Voltage rating: 50 V (exact match)
• Tolerance: ±20% (exact match)
• ESR @ 120Hz: 119 mOhm (exact match)
• Lifetime @ 105°C: 3000 Hrs (exact match)
• Operating temperature range: -40°C to 105°C (exact match)

Mechanical Compatibility Requirements:

• Mounting type: Through Hole (exact match)
• Package type: Radial, Can - Snap-In (exact match)
• Lead spacing: 10.00 mm (exact match)
• Polarization: Polar (exact match)

Compliance Requirements:

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

The substitute part SLP392M050C3P3 meets all electrical and compliance requirements. Physical dimensions (can diameter and height) differ between the main part and substitute; however, both maintain identical lead spacing and snap-in mounting compatibility, allowing functional substitution in applications where board space permits the dimensional variation.

Parameter Comparison

Engineering Selection Recommendations

Both the SLP392M050A7P3 and SLP392M050C3P3 are Active products manufactured by Cornell Dubilier Electronics within the same SLP0712TE series. Both parts are ROHS3 Compliant, REACH Unaffected, and carry MSL Level 1 classification, indicating equivalent environmental and regulatory compliance.

The primary distinction between these parts is physical form factor. The SLP392M050A7P3 features a 22.00 mm diameter can with a maximum seated height of 40.00 mm, while the SLP392M050C3P3 features a 25.00 mm diameter can with a maximum seated height of 30.00 mm. Both maintain identical 10.00 mm lead spacing and snap-in mounting compatibility.

Selection between these parts is determined by available board space and mechanical constraints. The SLP392M050C3P3 offers a more compact vertical profile (30 mm vs. 40 mm height), making it suitable for applications with height restrictions. The SLP392M050A7P3 accommodates applications where vertical space is available but horizontal space is constrained.

Electrical performance, including capacitance, voltage rating, ESR, ripple current handling, and thermal lifetime specifications, is functionally equivalent between both parts. Ripple current values differ marginally (within 1.3% at 120 Hz and 1.4% at 20 kHz), reflecting normal manufacturing variation within the same product series.

Frequently Asked Questions (FAQ)

Q: Can SLP392M050C3P3 be used as a direct replacement for SLP392M050A7P3?

A: Yes, provided board layout accommodates the dimensional differences. The SLP392M050C3P3 has a larger diameter (25.00 mm vs. 22.00 mm) but shorter height (30.00 mm vs. 40.00 mm). Lead spacing remains identical at 10.00 mm, and snap-in mounting compatibility is maintained. Electrical specifications are equivalent.

Q: Are there differences in electrical performance between these parts?

A: Electrical performance is equivalent. Both parts deliver 3900 µF capacitance at 50 V with ±20% tolerance, 119 mOhm ESR @ 120Hz, and 3000-hour lifetime at 105°C. Ripple current specifications differ marginally (2.23 A vs. 2.2 A @ 120 Hz; 2.79 A vs. 2.75 A @ 20 kHz), representing normal variation within the same product series.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution is based on exact equivalence in capacitance (3900 µF), voltage rating (50 V), tolerance (±20%), ESR (119 mOhm @ 120Hz), lifetime (3000 Hrs @ 105°C), operating temperature range (-40°C to 105°C), lead spacing (10.00 mm), mounting type (Through Hole), and package type (Radial, Can - Snap-In). Compliance certifications (ROHS3, REACH) must also match.

Q: Do both parts have the same compliance certifications?

A: Yes. Both SLP392M050A7P3 and SLP392M050C3P3 are ROHS3 Compliant, REACH Unaffected, and carry MSL Level 1 classification. They are equivalent from a regulatory and environmental standpoint.

Q: Which part should be selected for space-constrained applications?

A: The SLP392M050C3P3 is suitable for applications with vertical height constraints, as it provides a 10 mm reduction in seated height (30 mm vs. 40 mm). However, the larger diameter (25.00 mm vs. 22.00 mm) must be accommodated on the PCB.

Q: Are these parts interchangeable in all circuit applications?

A: Electrical interchangeability is confirmed. Mechanical interchangeability depends on PCB layout. Verify that the board design accommodates the dimensional differences in can diameter and height before substitution.
