Key Parameters

Substitute Part Grouping Explanation

The 461-400 qualifies as a parametric equivalent to the 461-420 based on the following critical parameters:

• LED Compatibility: Both support T1 and T1 3/4 LED types
• Material Composition: Both utilize natural nylon construction
• Compliance Profile: Both are ROHS3 compliant with MSL 1 (Unlimited) rating
• Manufacturer: Both are produced by Bivar Inc. within the same 461 series

The primary differentiation between these parts is standoff length: the 461-420 measures 0.420" (10.67mm) while the 461-400 measures 0.400" (10.16mm). This 0.020" (0.51mm) difference represents the allowable tolerance variation within the Bivar 461 series mounting pad family.

Parameter Comparison

Engineering Selection Recommendations

Both the 461-420 and 461-400 maintain active product status and are fully ROHS3 compliant with unlimited moisture sensitivity tolerance. The 461-400 maintains higher inventory availability (14,710 pieces) compared to the 461-420 (902 pieces), ensuring improved supply chain reliability.

Selection between these parts depends on the specific standoff height requirement within your PCB assembly. The 0.420" length of the 461-420 provides greater clearance between the LED and mounting surface, while the 0.400" length of the 461-400 offers a more compact profile. Both parts meet identical LED compatibility and material specifications, making them interchangeable where the 0.020" height difference is electrically and mechanically acceptable for the application.

Frequently Asked Questions (FAQ)

What determines if the 461-400 can substitute for the 461-420?

The 461-400 qualifies as a direct parametric substitute provided your application tolerates the 0.020" (0.51mm) reduction in standoff height. Both parts share identical LED compatibility (T1, T1 3/4), material composition (natural nylon), and compliance certifications (ROHS3, MSL 1).

Are there mechanical or electrical differences between these parts?

No mechanical or electrical differences exist beyond the specified standoff length. Both parts use identical nylon material, support the same LED package sizes, and carry the same regulatory certifications.

What is the impact of the height difference on LED assembly?

The 0.420" standoff of the 461-420 provides 0.020" additional clearance compared to the 461-400. This difference affects vertical positioning of the LED relative to the PCB. Substitution is valid only if your PCB design tolerates this reduced clearance without compromising component placement, trace routing, or thermal performance.

Do both parts meet the same compliance requirements?

Yes. Both the 461-420 and 461-400 are ROHS3 compliant and carry an MSL rating of 1 (Unlimited), indicating identical moisture sensitivity performance and regulatory acceptance.

Which part should be selected for new designs?

For new designs without height constraints, the 461-400 is preferred due to superior inventory availability (14,710 pieces versus 902 pieces), ensuring improved procurement reliability and reduced lead times.
