Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TAP155M016SCS is determined by the following parameters:

Fixed Parameters (Must Match):

• Capacitance: 1.5 µF
• Type: Conformal Coated
• Mounting Type: Through Hole
• Package / Case: Radial
• Physical Dimensions: 0.177" Dia (4.50 mm), Height 0.276" (7.00 mm), Lead Spacing 0.098" (2.50 mm)
• Manufacturer Size Code: A
• Operating Temperature Range: -55°C to 125°C
• Lifetime @ Temperature: 1000 Hrs @ 85°C
• Series: TAP
• Product Status: Active
• RoHS Status: ROHS3 Compliant
• REACH Status: REACH Unaffected

Variable Parameters (Allowed to Differ):

• Tolerance: ±20% (main part) to ±10% (substitute parts)
• Voltage - Rated: 16 V (main part) to 25 V or 35 V (substitute parts)

All three substitute parts maintain identical capacitance, physical form factor, and environmental specifications while offering improved tolerance and higher voltage ratings.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts maintain Active product status and full compliance with ROHS3 and REACH regulations. Selection between the main part and substitute parts depends on circuit voltage requirements and tolerance specifications.

TAP155K016SCS provides identical voltage rating to the main part with improved tolerance specification (±10% versus ±20%), suitable for applications requiring tighter capacitance control at the same 16 V operating point.

TAP155K025SCS and TAP155K035SCS offer higher voltage ratings (25 V and 35 V respectively) while maintaining the same 1.5 µF capacitance and physical form factor. These parts are suitable for circuits operating at higher voltage levels or requiring increased voltage safety margins. Both substitute parts also feature reduced ESR values (8 Ohm and 6 Ohm respectively) compared to the main part.

Frequently Asked Questions (FAQ)

Q: Can TAP155K016SCS be used as a direct replacement for TAP155M016SCS?

A: Yes. Both parts share identical voltage rating (16 V), capacitance (1.5 µF), physical dimensions, and operating temperature range. The primary difference is tolerance specification: TAP155K016SCS offers ±10% tolerance compared to ±20% for the main part. This substitution is electrically and mechanically compatible.

Q: What is the advantage of using TAP155K025SCS or TAP155K035SCS?

A: These parts provide higher voltage ratings (25 V and 35 V) while maintaining the same 1.5 µF capacitance and radial package dimensions. They are suitable for circuits requiring higher voltage operation or additional voltage safety margin. Both also feature lower ESR values, which may benefit high-frequency or high-current applications.

Q: Are all substitute parts physically interchangeable?

A: Yes. All parts listed share identical physical dimensions (0.177" diameter, 0.276" maximum height, 0.098" lead spacing) and radial through-hole mounting configuration. They are mechanically interchangeable on PCBs designed for the TAP series Size Code A package.

Q: Do substitute parts maintain the same environmental specifications?

A: Yes. All substitute parts operate across the same temperature range (-55°C to 125°C) and maintain identical lifetime specifications (1000 Hrs @ 85°C). All are conformal coated and maintain ROHS3 compliance and REACH unaffected status.

Q: Which substitute part should be selected for a 25 V circuit?

A: TAP155K025SCS is rated for 25 V operation and maintains the 1.5 µF capacitance requirement. This part is suitable for circuits operating at or below 25 V.

Q: Which substitute part should be selected for a 35 V circuit?

A: TAP155K035SCS is rated for 35 V operation and maintains the 1.5 µF capacitance requirement. This part is suitable for circuits operating at or below 35 V.
