Key Parameters

Substitute Part Grouping Explanation

The 456-500 is designated as a parametric equivalent to the 456-490. Both components share the following critical parameters that govern substitution:

• LED Size Compatibility: Both support T1 and T1 3/4 LED packages
• Material Composition: Both are manufactured from nylon
• Color: Both are white
• Series Classification: Both belong to the Bivar Inc. 456 series
• Regulatory Compliance: Both are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity level
• Packaging: Both are supplied in bag format
• Duty Classification: Both carry ECCN EAR99 and HTSUS 8547.20.0000 codes

The primary dimensional difference is the length specification: 456-490 measures 0.490" (12.45mm) while 456-500 measures 0.500" (12.70mm), representing a 0.010" (0.25mm) variation in standoff height.

Parameter Comparison

Engineering Selection Recommendations

Both the 456-490 and 456-500 maintain Active product status with full ROHS3 compliance and unlimited moisture sensitivity classification, confirming their suitability for current production environments. The 456-500 exhibits significantly higher inventory availability at 2933 pieces compared to 771 pieces for the 456-490. Selection between these parts is determined by dimensional requirements, as the 0.010" (0.25mm) length difference directly affects standoff height in the assembly. Compliance certifications are equivalent across both options, permitting selection based solely on mechanical fit criteria within the target application.

Frequently Asked Questions (FAQ)

Q: What is the primary difference between the 456-490 and 456-500? A: The primary difference is the standoff length. The 456-490 measures 0.490" (12.45mm), while the 456-500 measures 0.500" (12.70mm), a dimensional variation of 0.010" (0.25mm).

Q: Are both parts interchangeable in all applications? A: Both parts are mechanically and electrically equivalent for LED sizing and material composition. Substitution is valid only when the specific standoff height does not create interference or spacing violations in the target assembly.

Q: What LED packages are supported by these mounting pads? A: Both the 456-490 and 456-500 support T1 and T1 3/4 LED package sizes.

Q: Do these parts require any special moisture or thermal handling? A: Both components carry Moisture Sensitivity Level 1 (Unlimited), indicating no special moisture control measures are required during storage or handling.

Q: What is the regulatory status of these components? A: Both components are ROHS3 compliant and carry ECCN EAR99 classification with HTSUS 8547.20.0000 codes.

Q: Which part should be selected if inventory is a consideration? A: The 456-500 carries significantly higher inventory at 2933 pieces compared to 771 pieces for the 456-490. Selection should confirm that the 0.010" (0.25mm) additional height is acceptable within mechanical design constraints.
