Substitute Part Grouping Explanation

Substitution eligibility for the TAP685K050HSB is determined by strict equivalence across the following critical parameters:

• Capacitance: 6.8 µF (exact match required)
• Tolerance: ±10% (exact match required)
• Voltage Rating: 50 V (exact match required)
• Type: Conformal Coated (exact match required)
• ESR: 2 Ohm (exact match required)
• Operating Temperature Range: -55°C ~ 125°C (exact match required)
• Lifetime @ Temp.: 1000 Hrs @ 85°C (exact match required)
• Mounting Type: Through Hole (exact match required)
• Package / Case: Radial (exact match required)
• Manufacturer Size Code: H (exact match required)
• RoHS Status: ROHS3 Compliant (exact match required)

The TAP685K050GSB qualifies as a direct substitute based on full alignment with all critical electrical and mechanical parameters. The primary distinction is lead spacing, which differs between the two parts and must be evaluated for PCB layout compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both TAP685K050HSB and TAP685K050GSB maintain Active product status and are ROHS3 compliant with REACH Unaffected designation. Selection between these parts is determined by PCB layout requirements, specifically lead spacing compatibility. The TAP685K050HSB features 0.250" (6.35mm) lead spacing, while the TAP685K050GSB features 0.125" (3.18mm) lead spacing. All other electrical and mechanical specifications are identical, ensuring functional equivalence when lead spacing accommodates the PCB design.

Frequently Asked Questions (FAQ)

Q: Can TAP685K050GSB replace TAP685K050HSB in all applications?

A: Electrical and thermal performance are identical. Substitution is valid only if the PCB footprint accommodates the 0.125" (3.18mm) lead spacing of the TAP685K050GSB, as opposed to the 0.250" (6.35mm) spacing of the TAP685K050HSB.

Q: Are there differences in reliability or lifetime between these parts?

A: No. Both parts specify 1000 Hrs @ 85°C lifetime and operate across the identical temperature range of -55°C ~ 125°C.

Q: Do both parts meet the same compliance standards?

A: Yes. Both TAP685K050HSB and TAP685K050GSB are ROHS3 compliant, REACH Unaffected, and classified under ECCN EAR99 with HTSUS code 8532.21.0040.

Q: What is the primary difference between these substitute parts?

A: Lead spacing is the only dimensional difference. The TAP685K050HSB has 0.250" (6.35mm) lead spacing, while the TAP685K050GSB has 0.125" (3.18mm) lead spacing. All other parameters, including capacitance, voltage rating, ESR, and package dimensions, are identical.

Q: Can I use either part interchangeably on the same PCB?

A: No. PCB hole spacing must match the lead spacing of the selected part. Verify your PCB design specifications before selecting either component.
