Substitute Part Grouping Explanation

Substitution eligibility for the ECO-S1HP682DA is determined by strict adherence to the following core parameters:

Capacitance: 6800 µF (exact match required)
Voltage Rating: 50 V (exact match required)
Tolerance: ±20% (exact match required)
Package / Case: Radial, Can - Snap-In (exact match required)
Lead Spacing: 0.394" (10.00 mm) (exact match required)
Mounting Type: Through Hole (exact match required)
Operating Temperature Range: -40°C ~ 85°C (exact match required)
Polarization: Polar (exact match required)

All four substitute parts listed meet these mandatory criteria. Variations in ESR, ripple current ratings, physical dimensions (diameter and height), and lifetime specifications are permissible within the substitution scope, as these parameters do not affect the core electrical and mechanical compatibility of the component in the application circuit.

Engineering Selection Recommendations

All four substitute parts are manufactured by Cornell Dubilier Electronics (CDE) and carry active product status, ensuring long-term availability and supply chain continuity. The SLPX series parts (SLPX682M050A9P3, SLPX682M050C7P3, SLPX682M050E5P3) are ROHS3 compliant and REACH unaffected, providing regulatory alignment for modern applications. The 380LQ682M050J022 is ROHS3 compliant and REACH unaffected as well.

Selection between substitute parts should be based on physical space constraints within the application. The SLPX682M050A9P3 offers the smallest diameter (22.00 mm) but the greatest height (50.00 mm). The SLPX682M050C7P3 and 380LQ682M050J022 provide mid-range dimensions (25.00 mm diameter). The SLPX682M050E5P3 matches the original diameter (30.00 mm) while offering reduced height (35.00 mm) compared to the ECO-S1HP682DA.

The 380LQ682M050J022 operates with a reduced lifetime specification of 2000 hours at 85°C, compared to 3000 hours for the original and other SLPX alternatives. This parameter should be evaluated against application duty cycle requirements.

Frequently Asked Questions (FAQ)

Q: Can SLPX682M050A9P3, SLPX682M050C7P3, SLPX682M050E5P3, and 380LQ682M050J022 be used interchangeably with ECO-S1HP682DA?

A: Yes, all four parts meet the mandatory substitution criteria: identical capacitance (6800 µF), voltage rating (50 V), tolerance (±20%), package type (radial, can snap-in), lead spacing (10.00 mm), and operating temperature range (-40°C to 85°C). Physical dimensions and ESR values differ but do not affect electrical compatibility.

Q: What are the physical dimension differences between substitute parts?

A: Substitute parts vary in diameter and height. SLPX682M050A9P3 has a 22.00 mm diameter and 50.00 mm height. SLPX682M050C7P3 and 380LQ682M050J022 both have 25.00 mm diameter with heights of 40.00 mm and 32.00 mm respectively. SLPX682M050E5P3 matches the original 30.00 mm diameter with 35.00 mm height. PCB layout and enclosure clearance must be verified before selection.

Q: How do ESR values affect substitution suitability?

A: The original ECO-S1HP682DA specifies 49 mOhm ESR at 120 Hz. Substitute parts range from 68 mOhm (SLPX series) to 73 mOhm (380LQ series). Higher ESR increases heat dissipation and may affect ripple current performance. Applications with strict ripple current or thermal constraints should prioritize SLPX series parts with lower ESR values.

Q: What is the significance of the 2000-hour versus 3000-hour lifetime specification?

A: The 380LQ682M050J022 specifies 2000 hours at 85°C, while the original and SLPX alternatives specify 3000 hours. This affects component longevity in continuous-duty applications at elevated temperatures. Applications requiring extended operational life should select SLPX series parts.

Q: Are all substitute parts RoHS and REACH compliant?

A: All four substitute parts are ROHS3 compliant. The SLPX series (SLPX682M050A9P3, SLPX682M050C7P3, SLPX682M050E5P3) and 380LQ682M050J022 are REACH unaffected, meeting modern regulatory requirements for electronics manufacturing and distribution.
