UP050B682K-A-BZ Equivalent & Substitute Parts

Part Overview

The UP050B682K-A-BZ is a 6800 pF ceramic capacitor rated at 50V with axial through-hole mounting, manufactured by Taiyo Yuden. This component features a B temperature coefficient and operates across -25°C to 85°C. The part is classified as obsolete, necessitating identification of equivalent alternatives for ongoing production and maintenance applications. Substitute parts must maintain the 6800 pF capacitance value, 50V voltage rating, and ±10% tolerance while accommodating different mounting technologies and temperature characteristics.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the UP050B682K-A-BZ is determined by strict electrical and mechanical compatibility criteria. All substitute parts must satisfy the following mandatory parameters:

Electrical Requirements:

• Capacitance: 6800 pF (exact match)
• Tolerance: ±10% (exact match)
• Voltage Rating: 50V (exact match or higher)

Compliance Requirements:

• RoHS3 Compliant status
• Moisture Sensitivity Level 1 or Not Applicable

Mechanical Considerations:

• Mounting technology may differ (through-hole axial or surface-mount MLCC)
• Temperature coefficient may vary (B or X7R acceptable based on application requirements)
• Operating temperature range may extend beyond original specification

Two substitute categories are identified: direct axial replacements maintaining identical form factor, and surface-mount alternatives for circuit redesign scenarios.

Engineering Selection Recommendations

For Direct Axial Replacement (Through-Hole Mounting):

The A682K15X7RF5UAA from Vishay Beyschlag/Draloric/BC Components is the primary substitute for through-hole applications. This part maintains axial form factor compatibility with the original UP050B682K-A-BZ, enabling direct board-level substitution without layout modifications. The A682K15X7RF5UAA carries Active product status, ensuring long-term availability and supply chain stability. The X7R temperature coefficient provides extended operating range (-55°C ~ 125°C) compared to the original B coefficient specification, offering improved thermal stability in demanding environments. Both parts are ROHS3 compliant and feature identical electrical specifications (6800 pF, ±10%, 50V).

For Surface-Mount Redesign (MLCC Technology):

The UMK105B7682KV-F from Taiyo Yuden represents the surface-mount alternative for circuit board redesign scenarios. This 0402 (1005 Metric) MLCC maintains electrical equivalence with the original part while enabling modern PCB assembly processes. The UMK105B7682KV-F carries Not For New Designs status, indicating it remains available for legacy system support but is not recommended for new product development. The X7R temperature coefficient and extended operating range (-55°C ~ 125°C) provide thermal performance superior to the original specification. ROHS3 compliance and MSL 1 rating ensure environmental and moisture handling compatibility.

Selection Criteria:

• Existing through-hole designs: Select A682K15X7RF5UAA for direct substitution
• New product development: Select A682K15X7RF5UAA (Active status)
• Surface-mount redesign: Select UMK105B7682KV-F for MLCC implementation
• Legacy system support: UMK105B7682KV-F remains available despite Not For New Designs status

Frequently Asked Questions (FAQ)

Q: Can the A682K15X7RF5UAA directly replace the UP050B682K-A-BZ on existing PCBs?

A: Yes. Both parts feature axial through-hole mounting with identical electrical specifications (6800 pF, ±10%, 50V). Physical dimensions differ slightly (0.098" Dia x 0.150" L versus 0.087" Dia x 0.126" L), but both accommodate standard axial component footprints. No circuit modifications are required.

Q: What is the difference between B and X7R temperature coefficients?

A: The B coefficient specifies capacitance change over -25°C to 85°C. The X7R coefficient specifies change over -55°C to 125°C with tighter tolerance. X7R provides broader temperature stability and is suitable for applications requiring extended operating ranges.

Q: Is the UMK105B7682KV-F suitable for new product designs?

A: The UMK105B7682KV-F carries Not For New Designs status. For new development, the A682K15X7RF5UAA (Active status) is the recommended choice. The UMK105B7682KV-F remains available for legacy system support and maintenance applications.

Q: What are the packaging differences between the substitute parts?

A: The A682K15X7RF5UAA maintains axial through-hole packaging identical to the original UP050B682K-A-BZ, suitable for conventional PCB assembly. The UMK105B7682KV-F uses 0402 (1005 Metric) surface-mount MLCC packaging, requiring modern pick-and-place assembly equipment and surface-mount PCB design.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. Both the A682K15X7RF5UAA and UMK105B7682KV-F are ROHS3 compliant, matching the environmental compliance status of the original UP050B682K-A-BZ.

Q: What is the inventory status of substitute parts?

A: The A682K15X7RF5UAA has 1036 pcs in stock. The UMK105B7682KV-F has 133480 pcs in stock. Both parts are available for immediate procurement.
