Key Parameters

Substitute Part Grouping Explanation

Substitution of the LTA-1000P is determined by the following critical parameters:

• Configuration: Bar - 10 Wide, DIP format
• Color: Red LED array (x 10)
• Mounting Type: Through Hole
• Lens Style: Rectangle with Flat Top
• Lens Size: Mechanical compatibility within 5.00mm to 5.08mm width and 1.74mm to 1.78mm height
• Voltage Rating: Operating range 2.1V to 2.35V
• Current: Maximum 15mA per segment
• Wavelength: Red spectrum (697nm to 700nm)
• Compliance: ROHS3 Compliant, MSL 1

The SSA-LXB10HW-GF/LP from Lumex Opto/Components Inc. meets all substitution criteria within these electrical and mechanical tolerances.

Parameter Comparison

Engineering Selection Recommendations

The SSA-LXB10HW-GF/LP is the qualified substitute for the obsolete LTA-1000P based on the following factors:

• Both components maintain ROHS3 compliance and MSL 1 rating, ensuring regulatory and environmental compatibility
• Active product status of the SSA-LXB10HW-GF/LP ensures long-term availability and supply chain continuity
• Electrical parameters fall within acceptable operating ranges: voltage differential of 0.25V and current reduction of 5mA are within typical circuit design tolerances
• Mechanical form factor compatibility is confirmed through matching DIP configuration, through-hole mounting, and rectangular lens geometry with dimensions within 0.08mm variance
• Red wavelength specification (700nm vs 697nm) maintains visual consistency in indicator applications
• Diffused lens type of the substitute provides enhanced light distribution compared to the original specification

Frequently Asked Questions (FAQ)

Q: Can the SSA-LXB10HW-GF/LP be used as a direct replacement for the LTA-1000P without circuit modification?

A: The SSA-LXB10HW-GF/LP is mechanically and electrically compatible for direct substitution in through-hole applications. The 0.25V voltage increase and 5mA current reduction are within standard design tolerances for LED indicator circuits. Verify that your current-limiting resistor values accommodate the 10mA maximum current specification of the substitute part.

Q: What is the impact of the diffused lens type on the SSA-LXB10HW-GF/LP compared to the standard lens of the LTA-1000P?

A: The diffused, white lens of the SSA-LXB10HW-GF/LP provides broader light distribution with a 160° viewing angle. This results in improved visibility across a wider range of viewing positions compared to the original part, which is beneficial for indicator applications requiring visibility from multiple angles.

Q: Are there any compliance or certification differences between these parts?

A: Both the LTA-1000P and SSA-LXB10HW-GF/LP maintain ROHS3 compliance and MSL 1 (Unlimited) ratings. The SSA-LXB10HW-GF/LP additionally carries REACH Unaffected status. Both components share identical ECCN (EAR99) and HTSUS (8541.41.0000) classifications.

Q: What is the significance of the LTA-1000P being classified as obsolete?

A: Obsolete status indicates that the LTA-1000P is no longer manufactured or supported by Lite-On Inc. The SSA-LXB10HW-GF/LP, with active product status, ensures continued availability, technical support, and supply chain reliability for new designs and ongoing production requirements.

Q: How do the lens dimensions affect mechanical fit in existing PCB layouts?

A: The SSA-LXB10HW-GF/LP lens dimensions (5.00mm x 1.74mm) are slightly smaller than the LTA-1000P (5.08mm x 1.78mm), with a maximum variance of 0.08mm. This minor reduction is within typical PCB tolerance specifications and should not affect mechanical fit in standard through-hole mounting applications. Verify clearance in your specific PCB layout if tight mechanical constraints exist.
