Key Parameters

Substitute Part Grouping Explanation

Substitution of the 5912122302F is based on strict equivalence across the following parameters:

• Mechanical Compatibility: Identical lens style (round with domed top), lens diameter (2.85mm), and mounting configuration (Surface Mount, Right Angle)
• Electrical Configuration: Single LED configuration matching the original design
• Manufacturer Consistency: Same manufacturer (Dialight) and series (591) ensures design continuity
• Environmental Rating: Matching Moisture Sensitivity Level (MSL 2, 1 Year) maintains handling and storage requirements

The substitute part 5912122302NF satisfies all these criteria while offering active product status and improved regulatory compliance.

Parameter Comparison

Engineering Selection Recommendations

The 5912122302NF serves as the direct functional equivalent to the 5912122302F. Selection between these parts should be based on the following criteria:

Use 5912122302F only if:

• Existing inventory stock is available and acceptable for your application timeline
• Legacy system documentation explicitly requires this part number
• RoHS non-compliance is acceptable within your regulatory framework

Use 5912122302NF for:

• New designs and production builds
• Applications requiring ROHS3 compliance
• Systems subject to REACH regulations
• Long-term supply chain continuity, as this part maintains active manufacturing status
• Procurement requiring current ECCN classification (EAR99)

Both parts maintain identical mechanical and environmental specifications, ensuring direct form-fit-function compatibility in Surface Mount, Right Angle LED Circuit Board Indicator applications.

Frequently Asked Questions (FAQ)

Q: Can the 5912122302NF be used as a direct replacement for the 5912122302F in existing assemblies?

A: Yes. Both parts share identical mechanical dimensions (2.85mm domed lens), mounting configuration (Surface Mount, Right Angle), and environmental ratings (MSL 2). The parts are functionally interchangeable at the circuit board level.

Q: What is the primary difference between these two part numbers?

A: The 5912122302NF is the active production equivalent of the obsolete 5912122302F. The substitute part includes ROHS3 compliance and REACH Unaffected status, whereas the original part is RoHS non-compliant. Both maintain identical form factor and environmental specifications.

Q: Does the change from RoHS non-compliant to ROHS3 compliant affect circuit board assembly?

A: No. RoHS compliance status relates to material composition and manufacturing processes, not electrical or mechanical performance. The parts are assembly-compatible without design modifications.

Q: Are there any handling or storage differences between these parts?

A: Both parts carry identical Moisture Sensitivity Level ratings (MSL 2, 1 Year), requiring the same handling, storage, and reflow procedures.

Q: Why is the 5912122302F listed as obsolete?

A: The 5912122302F has been superseded by the 5912122302NF in Dialight's active product portfolio. The newer part number incorporates current regulatory compliance standards while maintaining the same mechanical and functional specifications.

Q: Can I mix 5912122302F and 5912122302NF parts in the same production batch?

A: Yes. Both parts are mechanically and functionally equivalent. However, documentation should clearly identify which part number is used in each assembly for traceability and compliance purposes.
