UP050CH681J-A-BZ Equivalent & Substitute Parts

Part Overview

The UP050CH681J-A-BZ is a 680 pF ceramic capacitor rated at 50V with C0H temperature coefficient, manufactured by Taiyo Yuden in axial through-hole configuration. This part is classified as obsolete, necessitating identification of equivalent alternatives for ongoing applications and new designs. Substitute parts must maintain the core electrical specifications (680 pF capacitance, ±5% tolerance, 50V rating) while accommodating different mounting technologies and temperature performance characteristics.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict adherence to the following electrical and mechanical parameters:

Primary Electrical Criteria:

• Capacitance value: 680 pF (exact match required)
• Tolerance: ±5% (exact match required)
• Voltage rating: 50V minimum (equal or higher acceptable)
• Temperature coefficient: C0H or equivalent stability class (C0G/NP0 acceptable as superior alternative)

Secondary Compatibility Criteria:

• RoHS3 compliance (mandatory for regulatory alignment)
• Moisture sensitivity level: 1 (Unlimited) or equivalent
• Operating temperature range: Must encompass or exceed -25°C ~ 85°C

Mounting Considerations:

• Through-hole axial configuration (primary substitute category)
• Surface-mount alternatives (secondary category for design flexibility)

Two substitute parts meet these criteria with different mounting technologies and enhanced temperature performance.

Parameter Comparison

Engineering Selection Recommendations

For Direct Through-Hole Replacement:

The A681J15C0GF5UAA (Vishay Beyschlag/Draloric/BC Components) is the primary equivalent for through-hole applications. This part maintains axial configuration compatibility with existing PCB layouts and provides superior temperature stability through C0G/NP0 temperature coefficient classification. The part carries Active product status and ROHS3 compliance, supporting both legacy system maintenance and new design integration. Operating temperature range extends to -55°C ~ 125°C, exceeding the original specification.

For Surface-Mount Design Transitions:

The UMK105CH681JV-F (Taiyo Yuden) provides electrical equivalence in surface-mount 0402 package format. This part maintains manufacturer continuity and identical electrical specifications (680 pF, ±5%, 50V, C0H). The Not For New Designs status indicates limited long-term availability; however, current inventory of 16,324 units supports near-term production requirements. Extended operating temperature range (-55°C ~ 125°C) accommodates broader environmental applications.

Compliance and Regulatory Alignment:

All substitute parts maintain ROHS3 compliance and EAR99 export classification, ensuring regulatory continuity with the original part. Moisture sensitivity levels remain at MSL 1 (Unlimited) or equivalent, preserving handling and storage protocols.

Frequently Asked Questions (FAQ)

Q: Can the UMK105CH681JV-F replace the UP050CH681J-A-BZ in existing through-hole designs?

A: No. The UMK105CH681JV-F is a surface-mount 0402 package component, incompatible with through-hole PCB layouts. The A681J15C0GF5UAA is the appropriate through-hole substitute.

Q: What is the difference between C0H and C0G/NP0 temperature coefficients?

A: Both are low-distortion ceramic dielectric types. C0G/NP0 (represented in the A681J15C0GF5UAA) provides superior temperature stability across the -55°C ~ 125°C range. C0H (original specification) is rated for -25°C ~ 85°C. The A681J15C0GF5UAA's C0G/NP0 classification represents enhanced performance within the original operating window.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. Both UMK105CH681JV-F and A681J15C0GF5UAA carry ROHS3 compliance certification, matching the original part's regulatory status.

Q: What is the inventory status of substitute parts?

A: The A681J15C0GF5UAA (through-hole, Active status) has 789 units in stock. The UMK105CH681JV-F (surface-mount, Not For New Designs) has 16,324 units available. The original UP050CH681J-A-BZ (Obsolete) has 887 units remaining.

Q: Can the A681J15C0GF5UAA be used in new designs?

A: Yes. The A681J15C0GF5UAA carries Active product status, supporting new design integration. The UMK105CH681JV-F is classified Not For New Designs and should be reserved for legacy system support only.

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

A: The UP050CH681J-A-BZ (original) measures 0.087" Dia x 0.126" L. The A681J15C0GF5UAA measures 0.098" Dia x 0.150" L, requiring verification of PCB layout clearances. The UMK105CH681JV-F measures 0.039" L x 0.020" W (surface-mount), requiring PCB redesign for implementation.

Q: Do all parts share the same lead spacing?

A: Lead spacing data is not provided for the original part or A681J15C0GF5UAA. The UMK105CH681JV-F, as a surface-mount component, does not use traditional lead spacing. Physical verification is required for through-hole applications.
