455-310 LED Mounting Pad - Equivalent & Substitute Parts

Part Overview

The 455-310 is a T1/T1 3/4 LED standoff mounting pad manufactured by Bivar Inc. in white nylon with a 0.310" (7.87mm) length. This component is designed to provide mechanical support and positioning for LED assemblies in electronic equipment. The product maintains Active status with full RoHS3 compliance and unlimited moisture sensitivity rating. Alternative equivalent parts become necessary when inventory constraints occur, specific lead time requirements must be met, or when design flexibility allows for compatible dimensional variations within the LED mounting pad category.

Key Parameters

Substitute Part Grouping Explanation

The 455-300 qualifies as a parametric equivalent for the 455-310 based on the following matching parameters:

• LED Type Support: Both support T1 and T1 3/4 LED configurations
• Material Composition: Both utilize white nylon construction
• Color: White finish in both variants
• Manufacturer: Both manufactured by Bivar Inc. within the 455 series
• Compliance & Certification: Both achieve RoHS3 compliance with MSL 1 (Unlimited) rating
• Product Status: Both carry Active product status

The primary distinction between these parts is the length specification: the 455-310 measures 0.310" (7.87mm) while the 455-300 measures 0.300" (7.62mm). This 0.010" (0.25mm) difference permits substitution when mechanical tolerance allows for slightly reduced standoff height.

Parameter Comparison

Engineering Selection Recommendations

Both the 455-310 and 455-300 are approved for direct substitution in designs where the 0.010" (0.25mm) length differential falls within assembly tolerances. Both parts maintain Active product status with full RoHS3 compliance and identical MSL ratings, ensuring regulatory and long-term reliability requirements are satisfied. The 455-300 currently carries higher inventory availability (1118 Pcs) compared to 455-310 (777 Pcs), making it suitable for high-volume procurement when mechanical clearance permits the reduced standoff height. Selection between these parts depends solely on dimensional requirements of the specific application rather than functional or compliance differences.

Frequently Asked Questions (FAQ)

Q: What is the primary difference between 455-310 and 455-300? A: The 455-310 provides a 0.310" (7.87mm) standoff height, while the 455-300 offers a 0.300" (7.62mm) height. All other functional parameters—LED type compatibility, material, color, compliance ratings, and product status—are identical.

Q: Can I substitute 455-300 for 455-310 in my design? A: Substitution is viable if the 0.010" (0.25mm) reduction in standoff height remains within the mechanical tolerances of your PCB layout and component clearance specifications.

Q: Are both parts RoHS compliant? A: Both the 455-310 and 455-300 achieve full RoHS3 compliance. Both also carry MSL 1 (Unlimited) moisture sensitivity rating, indicating no moisture-related handling restrictions during manufacturing.

Q: Which part should I select for new production? A: Selection depends on your mechanical design requirements. If 7.87mm standoff height is critical, use 455-310. If assembly tolerances accommodate 7.62mm height and higher inventory availability is beneficial, use 455-300. Both parts support identical LED types (T1, T1 3/4) and maintain equivalent regulatory status.

Q: Are these parts interchangeable at the assembly level? A: Yes, provided the 0.010" (0.25mm) length difference does not violate component clearance, PCB trace routing, or connector alignment requirements in your specific application.
