Key Parameters

Substitute Part Grouping Explanation

Substitution of the 5219455F is based on the following critical parameters:

• Color specification: Yellow
• Lens transparency: Diffused
• Lens size: 5.00mm diameter
• Mounting configuration: Through-hole radial
• Regulatory compliance: ROHS3 Compliant, REACH Unaffected
• Moisture sensitivity: MSL 1

The substitute part 5219248F maintains compatibility across these core parameters while offering active product status and improved availability.

Parameter Comparison

Engineering Selection Recommendations

The Dialight 5219248F is the designated manufacturer substitute for the obsolete 5219455F. Both components maintain identical regulatory compliance status (ROHS3 Compliant, REACH Unaffected) and moisture sensitivity classification (MSL 1). The substitute part is currently in active production with confirmed inventory availability of 2207 units.

Selection of the 5219248F is supported by matching optical and mechanical specifications: identical yellow diffused lens configuration, 5.00mm diameter form factor, and through-hole radial mounting. The substitute operates at reduced test current (10mA versus 20mA) and lower millicandela output (29mcd versus 34mcd), with specified forward voltage of 2.1V and 50° viewing angle.

Frequently Asked Questions (FAQ)

Q: Can the 5219248F directly replace the 5219455F in existing designs?

A: The 5219248F maintains mechanical and optical compatibility as a through-hole radial yellow diffused 5mm LED. Electrical parameter differences (test current and brightness) must be evaluated within the context of the specific application circuit.

Q: What are the key differences between these parts?

A: The primary differences are product status (obsolete versus active), test current specification (20mA versus 10mA), and millicandela rating (34mcd versus 29mcd). Both parts share identical lens color, transparency, size, mounting type, and regulatory compliance.

Q: Are there packaging differences?

A: The 5219455F packaging is listed as dash (-), while the 5219248F is supplied in bulk packaging. Both use the same T-1 3/4 supplier device package format for the 5mm radial LED configuration.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both the 5219455F and 5219248F are ROHS3 Compliant, REACH Unaffected, with MSL 1 (Unlimited) moisture sensitivity classification.

Q: What is the height specification for the substitute part?

A: The 5219248F has a maximum height of 9.66mm. The original part height specification is not provided in the available data.
