Substitute Part Grouping Explanation

The H278CYD serves as the designated substitute for the H278CUYC. This substitution is established based on the following criteria provided in the specifications:

Substitution Criteria:

• Same manufacturer (Bivar Inc.)
• Same product category (LED Circuit Board Indicator)
• Equivalent moisture sensitivity level (MSL 1 - Unlimited)
• Same export control classification (ECCN EAR99)
• Identical HTSUS code (8541.41.0000)
• Active product status with documented inventory

The H278CYD maintains the functional role of the H278CUYC as a LED indicator assembly while providing current manufacturing availability.

Parameter Comparison

Engineering Selection Recommendations

The H278CYD is the qualified substitute for the H278CUYC based on documented equivalent and substitute part relationships. Selection of the H278CYD is supported by:

• Identical manufacturer source (Bivar Inc.)
• Matching export control classifications and customs codes
• Equivalent moisture sensitivity ratings
• Active product status with confirmed inventory availability
• ROHS3 compliance

The transition from H278CUYC (Obsolete) to H278CYD (Active) provides access to a component with current manufacturing support and documented supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Why is the H278CUYC listed as Obsolete? A: The H278CUYC has reached end-of-life status. The manufacturer has designated H278CYD as the equivalent substitute for ongoing applications.

Q: Can H278CYD be used as a direct replacement for H278CUYC? A: H278CYD is the documented substitute part for H278CUYC. Both components share the same manufacturer, product category, export classification (EAR99), and moisture sensitivity rating (MSL 1 - Unlimited).

Q: What is the difference between the two parts? A: The primary difference is product status: H278CUYC is Obsolete while H278CYD is Active.
