Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LEDM-2-12 is determined by the following critical parameters:

• LED Type Compatibility: T1 form factor requirement
• Color: Black finish
• Mechanical Fit: Length tolerance within acceptable assembly range
• Material Composition: PVC or equivalent polymer material
• Regulatory Compliance: RoHS and REACH status alignment
• Moisture Sensitivity: MSL rating of 1 or lower

The identified substitute part meets these core substitution criteria through matching LED type, color, regulatory compliance, and moisture sensitivity specifications.

Parameter Comparison

Engineering Selection Recommendations

Both the LEDM-2-12 and 51 0420 are active production parts with full regulatory compliance. Selection between these parts should be based on:

• Availability: The 51 0420 offers higher inventory levels (1072 units vs. 850 units)
• Packaging Requirements: The 51 0420 is supplied in bulk packaging (500pcs/pkg), which may impact procurement logistics
• Length Tolerance: The 51 0420 has a slightly longer dimension (0.490" vs. 0.472"), which must be verified against assembly clearance requirements
• Material Difference: The 51 0420 uses Nylon instead of PVC, which may affect mechanical properties in specific thermal or chemical environments
• Regulatory Compliance: Both parts meet current RoHS and REACH requirements

Frequently Asked Questions (FAQ)

Q: Can the 51 0420 directly replace the LEDM-2-12 in all applications?

A: Both parts share the same T1 LED type, black color, MSL rating, and regulatory compliance status. However, the 51 0420 has a 0.018" (0.46mm) longer dimension and uses Nylon instead of PVC. Verify that your assembly design accommodates the increased length and that the material change does not affect performance in your specific application environment.

Q: What is the significance of the length difference between these parts?

A: The LEDM-2-12 measures 0.472" (11.99mm) while the 51 0420 measures 0.490" (12.45mm). This 0.018" difference may impact vertical spacing in densely packed assemblies or applications with tight clearance specifications. Confirm that your PCB layout and component placement allow for this variation.

Q: Are there material compatibility concerns between PVC and Nylon?

A: Both materials are suitable for LED spacer applications and meet MSL 1 requirements. Nylon offers different mechanical properties, including potentially higher temperature resistance. Evaluate your operating environment, thermal cycling requirements, and any chemical exposure to determine if the material substitution is appropriate.

Q: Do both parts have the same regulatory compliance?

A: Yes. Both the LEDM-2-12 and 51 0420 are RoHS compliant, REACH unaffected, and carry MSL 1 ratings. The 51 0420 specifically carries ROHS3 compliance, which represents the current RoHS standard.

Q: What packaging considerations apply to the 51 0420?

A: The 51 0420 is supplied in bulk packaging with 500 pieces per package. Confirm that your procurement and inventory management processes can accommodate bulk quantities if selecting this substitute.
