LCB110S Equivalent & Substitute Parts

Part Overview

The LCB110S is a solid-state relay (SSR) manufactured by IXYS Integrated Circuits Division, configured as a SPST-NC (1 Form B) switching device. This OptoMOS® series component operates with a 1.2VDC input signal and supports load voltages from 0V to 350V with a maximum load current of 120mA. The device is packaged in a 6-SMD surface-mount configuration with gull wing termination and is supplied in tube packaging.

The LCB110S maintains active product status and is ROHS3 compliant with unlimited moisture sensitivity rating (MSL 1). Equivalent and substitute parts are identified based on matching electrical performance parameters, mechanical compatibility, and regulatory compliance within the solid-state relay component category.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LCB110S is determined by the following criteria:

Packaging Format Equivalents: Parts with identical electrical specifications but different packaging formats (tube versus tape & reel) are direct equivalents. The LCB110STR represents the same component in tape & reel packaging, suitable for high-volume automated assembly operations.

Cross-Manufacturer Alternatives: The Vishay Semiconductor Opto Division LH1501 series provides functional substitution with modified electrical parameters. These parts maintain the same circuit configuration (SPST-NC), package geometry (6-SMD, 0.300" spacing), termination style (gull wing), and load voltage range (0V to 350V). The LH1501 series operates at a slightly higher input voltage (1.26VDC versus 1.2VDC) and delivers increased load current capacity (150mA versus 120mA) with reduced on-state resistance (20 Ohms versus 35 Ohms).

Regulatory Alignment: All substitute parts maintain ROHS3 compliance, unlimited MSL rating, and identical ECCN/HTSUS classifications, confirming regulatory equivalence.

Parameter Comparison

Engineering Selection Recommendations

IXYS LCB110S to LCB110STR: Direct substitution is applicable when transitioning from tube to tape & reel packaging. Both parts are manufactured by IXYS and maintain identical electrical specifications. Selection between these formats depends on assembly methodology: tube packaging suits lower-volume or manual placement operations, while tape & reel packaging is optimized for automated pick-and-place assembly systems.

IXYS LCB110S to Vishay LH1501 Series: The Vishay LH1501BAB and LH1501BABTR represent functional alternatives with enhanced electrical performance. These parts accept a marginally higher input voltage (1.26VDC versus 1.2VDC), deliver 25% greater load current capacity (150mA versus 120mA), and exhibit 43% lower on-state resistance (20 Ohms versus 35 Ohms). All parts maintain identical load voltage range, circuit configuration, package geometry, and regulatory compliance. Selection of the LH1501 series is appropriate when application requirements demand higher current switching capability or lower resistive losses.

All substitute parts maintain active product status and ROHS3 compliance, confirming suitability for current design and manufacturing environments.

Frequently Asked Questions (FAQ)

Q: Can LCB110STR replace LCB110S in existing designs?

A: Yes. LCB110STR is the tape & reel packaging variant of LCB110S with identical electrical specifications. The only difference is packaging format. Substitution is direct when the assembly process supports tape & reel input.

Q: Are Vishay LH1501 parts direct replacements for IXYS LCB110S?

A: LH1501 parts are functional equivalents, not direct replacements. They maintain the same circuit configuration, package geometry, and load voltage range. However, they operate at 1.26VDC input (versus 1.2VDC), support 150mA load current (versus 120mA), and exhibit 20 Ohms on-state resistance (versus 35 Ohms). Applications requiring the original 120mA specification must confirm that the higher current rating does not introduce design conflicts.

Q: What is the difference between LH1501BAB and LH1501BABTR?

A: Both are Vishay LH1501 series components with identical electrical specifications. LH1501BAB is supplied in tube packaging, while LH1501BABTR is supplied in tape & reel packaging. Selection depends on assembly equipment compatibility.

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

A: Yes. All listed parts are ROHS3 compliant, carry unlimited MSL rating (1), and share identical ECCN (EAR99) and HTSUS (8536.41.0030) classifications.

Q: Which substitute should be selected for high-volume production?

A: For high-volume automated assembly, tape & reel packaging (LCB110STR or LH1501BABTR) is standard. Between IXYS and Vishay options, selection depends on whether the application requires the original 120mA current specification (LCB110STR) or can benefit from the enhanced 150mA capacity (LH1501BABTR).
