Keystone Electronics 8918 Tri-Lead LED Standoff Equivalent & Substitute Parts

Part Overview

The Keystone Electronics 8918 is a tri-lead LED standoff spacer manufactured from black PVC with a length of 0.440" (11.18mm). This component is used for mounting and spacing LED assemblies in electronic applications. The part maintains Active product status and is ROHS3 compliant with unlimited moisture sensitivity rating (MSL 1). Substitute parts are necessary when specific length requirements differ or when inventory availability requires alternative part selection while maintaining equivalent mechanical and electrical characteristics.

Key Parameters

Substitute Part Grouping Explanation

Substitution of Keystone Electronics 8918 is determined by the following critical parameters that must remain constant across all equivalent parts:

• Manufacturer: Keystone Electronics
• Product Type: Tri-Lead LED Standoff Spacer
• Material: Black PVC
• LED Configuration: Tri-Lead
• Color: Black
• Packaging: Bulk
• Product Status: Active
• RoHS Compliance: ROHS3 Compliant
• MSL Rating: 1 (Unlimited)
• REACH Status: REACH Unaffected

The primary variable parameter allowing substitution is Length, which ranges from 0.420" to 0.460" across the equivalent part family. All substitute parts maintain identical material composition, electrical characteristics, compliance certifications, and mechanical mounting interfaces. Selection between 8918 and substitute parts depends solely on the required standoff height for the specific application.

Parameter Comparison

Engineering Selection Recommendations

Selection between Keystone Electronics 8918 and its substitute parts is based on the required standoff height for the application. All parts in this family share identical material composition (black PVC), tri-lead LED configuration, and compliance certifications (ROHS3, REACH Unaffected).

Part 8917 (0.420") provides the shortest standoff height and is suitable for applications requiring minimal spacing. Part 8918 (0.440") serves as the reference specification. Part 8919 (0.450") and Part 8920 (0.460") provide progressively greater standoff heights for applications requiring increased clearance or spacing.

All parts maintain Active product status and unlimited moisture sensitivity rating (MSL 1), ensuring consistent performance across the product family. Selection should be based on mechanical clearance requirements and PCB layout constraints specific to the application.

Frequently Asked Questions (FAQ)

Q: Can Keystone Electronics 8918 be directly replaced with part 8917, 8919, or 8920?

A: Direct replacement is possible only if the application tolerates the length variation. Part 8917 is 0.020" shorter, while parts 8919 and 8920 are 0.010" and 0.020" longer respectively. Mechanical clearance and PCB layout must accommodate the selected length.

Q: Are all substitute parts manufactured from the same material?

A: Yes. All parts in this family (8917, 8918, 8919, 8920) are manufactured from black PVC with identical tri-lead LED configuration and mounting characteristics.

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

A: Yes. All parts are ROHS3 compliant, REACH unaffected, and carry MSL rating 1 (unlimited moisture sensitivity). Compliance certifications are identical across the entire product family.

Q: What is the primary difference between these substitute parts?

A: The only functional difference is standoff height. Part lengths range from 0.420" to 0.460", allowing selection based on specific application spacing requirements.

Q: Are there any electrical differences between the substitute parts?

A: No. All parts are passive mechanical spacers with no electrical characteristics. Electrical performance is determined by the LED assembly, not the standoff component.

Q: Can these parts be used interchangeably in high-volume production?

A: Interchangeability depends on design specifications. If the application design specifies a particular length, only that part number should be used. If the design allows length tolerance, substitute parts with appropriate heights may be used.
