UP050CH102J-A-BZ Equivalent & Substitute Parts

Part Overview

The UP050CH102J-A-BZ is a 1000 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 and substitute components for ongoing applications and new designs. The axial package and specific electrical characteristics define the scope of suitable alternatives.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the UP050CH102J-A-BZ is determined by the following critical parameters:

Electrical Equivalence Requirements:

• Capacitance value: 1000 pF (exact match required)
• Voltage rating: 50V minimum
• Tolerance: ±5%
• Temperature coefficient: C0H or equivalent stability class

Mechanical Compatibility:

• Mounting type: Through-hole configuration for direct board-level replacement
• Package style: Axial lead format for existing PCB layouts

Regulatory Compliance:

• RoHS3 compliance mandatory for new procurement
• Moisture sensitivity level 1 acceptable

Two substitute categories are identified:

1. Direct Axial Equivalent (A102J15C0GF5UAA): Through-hole axial package maintaining identical mounting compatibility. Temperature coefficient upgraded to C0G/NP0 with extended operating range (-55°C ~ 125°C). Active product status supports long-term availability.

2. Surface Mount Alternative (UMK105CH102JV-F): 0402 package requiring PCB redesign and assembly process modification. Maintains identical electrical specifications with extended temperature range. Suitable for new designs with surface-mount capability.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement in Existing Designs:

The A102J15C0GF5UAA is the primary substitute for through-hole applications. This part maintains axial package compatibility, eliminating PCB layout modifications. The upgraded temperature coefficient (C0G/NP0) provides superior stability compared to the original C0H specification, with extended operating range (-55°C ~ 125°C). Active product status from Vishay Beyschlag ensures long-term availability and supply chain stability. RoHS3 compliance and REACH unaffected status satisfy current regulatory requirements.

For New Design Implementation:

The UMK105CH102JV-F surface-mount alternative is suitable for new PCB designs incorporating surface-mount assembly processes. This part maintains identical electrical specifications (1000 pF, ±5%, 50V, C0H) with extended temperature range capability. The 0402 package reduces board space requirements. However, this substitution requires PCB redesign and assembly process modification. Product status "Not For New Designs" indicates limited future support; therefore, this option is applicable only when design constraints necessitate surface-mount technology.

Compliance Verification:

All substitute parts maintain ROHS3 compliance and EAR99 export classification consistent with the original part. Moisture sensitivity level 1 (unlimited) for the UMK105CH102JV-F matches the original specification, eliminating special handling requirements.

Frequently Asked Questions (FAQ)

Q: Can the A102J15C0GF5UAA replace the UP050CH102J-A-BZ without PCB modification?

A: Yes. Both parts use axial through-hole packages with identical electrical specifications (1000 pF, ±5%, 50V). The A102J15C0GF5UAA has slightly larger physical dimensions (0.098" Dia x 0.150" L versus 0.087" Dia x 0.126" L), but this does not prevent direct substitution in standard through-hole applications. Verify PCB hole spacing and component clearance before installation.

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

A: Both are low-distortion ceramic temperature coefficients. C0G/NP0 provides tighter capacitance stability across temperature extremes, with specified tolerance of ±30 ppm/°C. C0H offers adequate stability for general-purpose applications. The A102J15C0GF5UAA upgrade to C0G/NP0 enhances performance in temperature-sensitive circuits.

Q: Why is the UMK105CH102JV-F marked "Not For New Designs"?

A: This designation indicates the manufacturer does not recommend this part for new product development due to potential future discontinuation or limited support. While currently available (39,876 pcs in stock), it is suitable only for legacy design maintenance or applications with specific surface-mount requirements where long-term availability is not critical.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. Both the A102J15C0GF5UAA and UMK105CH102JV-F are ROHS3 compliant, matching the original UP050CH102J-A-BZ specification. All parts are suitable for applications requiring RoHS compliance.

Q: What is the moisture sensitivity level, and does it affect handling?

A: The UP050CH102J-A-BZ and UMK105CH102JV-F both have moisture sensitivity level 1 (unlimited), indicating no special moisture control or baking procedures are required during storage or assembly. The A102J15C0GF5UAA has "Not Applicable" moisture sensitivity, as axial through-hole components do not require moisture management protocols.

Q: Can the UMK105CH102JV-F be used as a drop-in replacement?

A: No. The UMK105CH102JV-F uses 0402 surface-mount package technology, requiring PCB redesign and surface-mount assembly processes. This part is not a drop-in replacement for through-hole applications. It is suitable only for new designs incorporating surface-mount technology.
