TAP104J035SCS Equivalent & Substitute Parts

Part Overview

The TAP104J035SCS is a 0.1 µF conformal coated tantalum capacitor rated for 35 V with ±5% tolerance, manufactured by KYOCERA AVX in the TAP series. This radial through-hole component is designed for general-purpose applications requiring reliable performance across the -55°C to 125°C operating temperature range. The part is currently active and in stock with 640 units available. Substitute parts are identified when design requirements allow for tolerance variations while maintaining identical electrical and mechanical specifications across capacitance, voltage rating, package type, and physical dimensions.

Substitute Part Grouping Explanation

Substitute parts for the TAP104J035SCS are qualified based on the following criteria:

Identical capacitance value: 0.1 µF
Identical voltage rating: 35 V
Identical type: Conformal coated tantalum
Identical ESR: 26 Ohm
Identical mounting type: Through hole radial
Identical package dimensions: 0.177" Dia (4.50 mm), height 0.276" (7.00 mm), lead spacing 0.098" (2.50 mm)
Identical operating temperature range: -55°C ~ 125°C
Identical lifetime specification: 1000 Hrs @ 85°C
Identical compliance status: ROHS3 compliant

The only parameter variation among qualified substitutes is tolerance, which ranges from ±5% to ±20%. This variation does not affect mechanical fit, electrical performance in general-purpose applications, or compliance certifications.

Engineering Selection Recommendations

All three parts—TAP104J035SCS, TAP104K035SCS, and TAP104M035SCS—are active products manufactured by KYOCERA AVX with identical ROHS3 compliance status. Selection between these parts depends on tolerance requirements for the specific application:

TAP104J035SCS (±5% tolerance): Select when tighter capacitance tolerance is required for precision circuit operation.
TAP104K035SCS (±10% tolerance): Select when moderate tolerance is acceptable and higher inventory availability is beneficial.
TAP104M035SCS (±20% tolerance): Select when wider tolerance is acceptable and maximum inventory availability is required.

All parts share identical electrical performance characteristics, physical dimensions, and thermal specifications, ensuring direct mechanical and electrical interchangeability within the constraints of their respective tolerance bands.

Frequently Asked Questions (FAQ)

Q: Can TAP104K035SCS or TAP104M035SCS be used as direct replacements for TAP104J035SCS?

A: Yes, both parts are direct mechanical and electrical substitutes. The only difference is tolerance: TAP104J035SCS has ±5% tolerance, TAP104K035SCS has ±10% tolerance, and TAP104M035SCS has ±20% tolerance. All other specifications—capacitance, voltage rating, ESR, package dimensions, and operating temperature range—are identical.

Q: Are there any physical differences between these parts?

A: No. All three parts have identical physical dimensions: 0.177" diameter (4.50 mm), maximum seated height of 0.276" (7.00 mm), and lead spacing of 0.098" (2.50 mm). They are mechanically interchangeable in PCB layouts.

Q: Do all substitute parts meet the same compliance requirements?

A: Yes. All three parts are ROHS3 compliant and share identical REACH and ECCN classifications. They are suitable for applications with identical regulatory requirements.

Q: What is the difference between conformal coated and non-coated tantalum capacitors?

A: The conformal coating provides additional environmental protection. All three parts in this comparison are conformal coated, so this specification is consistent across all options.

Q: Which part should I select if inventory is a concern?

A: TAP104M035SCS has the highest inventory availability at 3969 units, followed by TAP104K035SCS at 3400 units, and TAP104J035SCS at 640 units. If tolerance requirements allow, TAP104M035SCS or TAP104K035SCS provide better supply security.
