Key Parameters

Substitute Part Grouping Explanation

The 461-520 has one parametric equivalent substitute: the 461-500. These parts are functionally equivalent based on the following allowed parameters:

Common Parameters (Substitution Basis):

• LED Package Compatibility: Both support T1 and T1 3/4 LED packages
• Material: Both are Nylon construction
• Color: Both are Natural finish
• RoHS Compliance: Both meet ROHS3 Compliant requirements
• Moisture Sensitivity: Both rated MSL 1 (Unlimited)
• Packaging Format: Both supplied in Bag packaging
• Manufacturer: Both from Bivar Inc. Series 461

Dimensional Variation (Allowed Tolerance):

• Length difference between 461-520 and 461-500 is 0.020" (0.51mm), representing a 3.8% reduction in standoff height

Parameter Comparison

Engineering Selection Recommendations

Both 461-520 and 461-500 are active products manufactured by Bivar Inc. with ROHS3 compliance and identical environmental ratings (MSL 1). Selection between these parts shall be based on:

1. Mechanical Assembly Requirements: The 0.520" length of the 461-520 provides additional standoff height compared to the 461-500 at 0.500". The appropriate part shall be selected based on PCB-to-LED vertical spacing requirements in the assembly design.

2. Inventory Availability: The 461-500 has higher current inventory (1170 units) compared to the 461-520 (847 units), providing superior supply assurance.

3. RoHS and Environmental Compliance: Both parts meet identical regulatory requirements and are suitable for applications requiring ROHS3 compliance with unlimited moisture exposure tolerance.

Frequently Asked Questions (FAQ)

Q: Are the 461-520 and 461-500 interchangeable in all applications? A: These parts are mechanically compatible with the same LED packages (T1, T1 3/4) and materials. However, the 0.020" (0.51mm) length difference must be evaluated against the specific assembly's vertical spacing tolerances. Substitution is only valid where this dimensional variation is acceptable to the design.

Q: What is the primary difference between these substitute parts? A: The sole dimensional difference is length: the 461-520 is 0.520" and the 461-500 is 0.500". All other parameters—material composition, LED compatibility, color, RoHS status, and moisture sensitivity rating—are identical.

Q: Can I use the 461-500 if my design specifies the 461-520? A: Substitution depends on whether the assembly design accommodates the shorter standoff height. If the design has tight vertical constraints or specifies the 0.520" length, the 461-500 may not meet mechanical requirements. Design verification is necessary prior to implementation.

Q: Are both parts ROHS3 compliant? A: Yes. Both the 461-520 and 461-500 are ROHS3 compliant with MSL rating of 1 (Unlimited moisture exposure tolerance), suitable for standard manufacturing and storage conditions.

Q: What packaging format is supplied? A: Both parts are supplied in Bag packaging format, consistent with standard component distribution for mounting hardware applications.
