SVC236-TB-E Equivalent & Substitute Parts

Part Overview

The SVC236-TB-E is a varactor diode manufactured by onsemi, configured as a 1 Pair Common Cathode dual varactor in a surface mount package. This component is classified as Obsolete, making identification of suitable substitutes essential for ongoing design support and production continuity. The part operates with a peak reverse voltage rating of 16 V and delivers a capacitance of 16.84 pF at 6.5 V and 1 MHz, with a capacitance ratio of 5 (C1/C6.5). Given its obsolete status, alternative components meeting equivalent electrical and mechanical specifications are required for new designs and legacy system maintenance.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SVC236-TB-E is evaluated based on the following critical parameters:

• Package Compatibility: Both parts must use SOT-23-3 surface mount packaging to ensure PCB layout compatibility
• Diode Configuration: Common cathode dual varactor structure for identical pinout functionality
• Voltage Rating: The substitute must meet or exceed the 16 V peak reverse voltage requirement
• Capacitance Characteristics: Capacitance value and ratio determine frequency tuning range and circuit performance
• Quality Factor (Q): Higher Q values indicate lower losses and improved circuit efficiency
• Operating Temperature Range: Must support the required thermal operating window
• Regulatory Compliance: RoHS and REACH compliance status for manufacturing and supply chain requirements

The SMV2022-004LF from Skyworks Solutions Inc. is identified as a substitute based on matching package type (SOT-23-3), common cathode configuration, and surface mount technology. However, key electrical parameters differ and must be evaluated for circuit-specific requirements.

Parameter Comparison

Engineering Selection Recommendations

Product Status Consideration: The SVC236-TB-E is obsolete, while the SMV2022-004LF is active. Active product status ensures ongoing availability, manufacturing support, and supply chain continuity.

Compliance & Certifications: The SVC236-TB-E carries ROHS3 compliance and REACH Unaffected status. The SMV2022-004LF compliance certifications are not specified in the provided data. Verification of regulatory compliance for the substitute part is necessary before implementation in regulated applications.

Electrical Parameter Differences: The SMV2022-004LF exhibits significantly higher peak reverse voltage (50 V vs. 16 V) and superior quality factor (500 vs. 70), indicating lower loss characteristics at higher frequencies. However, the SMV2022-004LF is classified as a Single diode type, whereas the SVC236-TB-E is a 1 Pair Common Cathode configuration. This structural difference affects circuit topology and pinout compatibility.

Selection Basis: Component selection must be based on circuit-specific requirements for voltage rating, capacitance tuning range, frequency of operation, and thermal performance. The provided electrical parameters form the basis for determining functional equivalence.

Frequently Asked Questions (FAQ)

Q: Can the SMV2022-004LF directly replace the SVC236-TB-E in existing designs?

A: Both components share the SOT-23-3 surface mount package and unlimited moisture sensitivity level. However, the SMV2022-004LF is classified as a Single diode type while the SVC236-TB-E is a 1 Pair Common Cathode configuration. This difference in diode structure affects pinout and circuit topology. Direct replacement requires verification of circuit compatibility based on the specific application requirements.

Q: What are the key differences in electrical performance?

A: The SMV2022-004LF provides higher peak reverse voltage (50 V vs. 16 V), superior quality factor (500 @ 4V, 500MHz vs. 70 @ 3V, 100MHz), and an extended operating temperature range (-55°C to 125°C vs. 125°C maximum). The SVC236-TB-E specifies capacitance characteristics (16.84 pF @ 6.5V, 1MHz with a ratio of 5), while the SMV2022-004LF capacitance data is not provided.

Q: Why is the SVC236-TB-E classified as obsolete?

A: Obsolete status indicates the manufacturer has discontinued production. The SMV2022-004LF, with active product status, represents a current alternative for new designs and ongoing production requirements.

Q: Are there compliance differences between these parts?

A: The SVC236-TB-E is ROHS3 compliant and REACH Unaffected. The SMV2022-004LF compliance certifications are not specified in the available data. Compliance verification is required before selecting the substitute for regulated applications.

Q: What packaging considerations apply to both parts?

A: Both components use SOT-23-3 surface mount packaging (also designated TO-236-3 or SC-59), ensuring identical PCB footprint compatibility. Both carry MSL 1 (Unlimited) moisture sensitivity ratings, indicating no special moisture handling requirements during storage or assembly.
