LED GREEN/RED DIFFUSED T-1 T/H 5219664F Equivalent & Substitute Parts

Part Overview

The Dialight 5219664F is a through-hole mounted dual-color LED indicator featuring green and red light emission in a T-1 package with diffused lens. This component provides discrete LED indication with 2.1V forward voltage for green and 2V for red operation at 20mA test current. The product is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the 5219664F is determined by the following critical parameters:

• Dual-color configuration: Green and red LED in single package
• Forward voltage compatibility: 2.1V green, 2V red operation
• Test current: 20mA for both colors
• Mounting interface: Through-hole radial 3-lead package
• Lens type: Diffused white lens
• Package form factor: T-1 standard
• Regulatory compliance: ROHS3 compliance required

The identified substitute parts (3BC-3-F and LTL1BEKVJNN) maintain electrical compatibility across forward voltage and test current specifications. Both substitutes are active products with current manufacturing status, diffused lens construction, and identical radial 3-lead through-hole mounting. Variations in millicandela rating, viewing angle, and wavelength characteristics remain within acceptable ranges for indicator applications while meeting the core functional and mechanical requirements.

Parameter Comparison

Engineering Selection Recommendations

Both substitute parts maintain electrical compatibility with the original 5219664F specification. Selection between 3BC-3-F and LTL1BEKVJNN depends on application requirements:

The 3BC-3-F (Bivar Inc.) offers moderate brightness increase (30mcd versus 12mcd/8mcd original) with narrower viewing angle (40° versus 80°), suitable for applications requiring focused indication in controlled viewing environments. This part maintains active product status with ROHS3 compliance and REACH unaffected classification.

The LTL1BEKVJNN (Lite-On Inc.) provides significantly higher brightness (110mcd for both colors) with comparable viewing angle (45°), appropriate for applications requiring enhanced visibility. This part carries active product status and ROHS3 compliance; however, REACH affected status requires verification against specific application regulatory requirements.

Both substitutes are physically smaller (5.30mm and 5.15mm height respectively versus 6.10mm original), which may require PCB layout verification for clearance compatibility. All three parts maintain identical forward voltage, test current, and radial 3-lead through-hole mounting interface.

Frequently Asked Questions (FAQ)

Q: Can the 3BC-3-F and LTL1BEKVJNN be used interchangeably with the 5219664F?

A: Both parts maintain identical forward voltage (2.1V green, 2V red) and test current (20mA) specifications, enabling direct electrical substitution. Physical dimensions differ slightly; verify PCB clearance for the reduced height of substitute parts (5.30mm and 5.15mm versus 6.10mm original).

Q: What is the primary difference between the two substitute options?

A: The LTL1BEKVJNN provides higher brightness output (110mcd) compared to the 3BC-3-F (30mcd). The 3BC-3-F offers narrower viewing angle (40° versus 45°). Forward voltage and test current remain identical across both substitutes.

Q: Are there configuration differences between the original and substitute parts?

A: The original 5219664F configuration is not specified. Both substitute parts are common cathode configuration. Verify circuit design compatibility with common cathode operation before implementation.

Q: Do the substitute parts meet the same regulatory requirements?

A: All three parts are ROHS3 compliant with MSL 1 (Unlimited) rating. The 3BC-3-F maintains REACH unaffected status matching the original. The LTL1BEKVJNN carries REACH affected status; applications subject to REACH regulations require compliance verification.

Q: What is the impact of wavelength differences between parts?

A: Peak wavelength variations (560nm to 575nm green; 630nm to 639nm red) represent normal manufacturing tolerances within the green and red spectrum ranges. Visual color appearance remains consistent across all three parts for indicator applications.

Q: Are there inventory or lead time considerations?

A: The original 5219664F is obsolete with 1,071 pieces in stock. The 3BC-3-F has 2,885 pieces available, and the LTL1BEKVJNN has 1,667 pieces in stock. Active product status for both substitutes ensures ongoing availability for future production requirements.
