FHD3C64X-H Equivalent & Substitute Parts

Part Overview

The FHD3C64X-H is a yellow-green 572nm LED indication component manufactured by Stanley Electric Co, designed for through-hole mounting in discrete 3mm applications. This part operates at a forward voltage of 1.9V with a test current of 10mA and delivers 100mcd luminous intensity. The component is classified as obsolete, necessitating identification of active equivalent parts for ongoing production and maintenance applications. Substitute parts must maintain compatibility across electrical characteristics, mechanical form factor, and mounting configuration while meeting current industry compliance standards.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the FHD3C64X-H are selected based on the following critical parameters that define functional and mechanical compatibility:

Electrical Compatibility Criteria:

• Color: Yellow-Green
• Wavelength - Dominant: 572-573nm range
• Wavelength - Peak: 575nm
• Mounting Type: Through Hole
• Package / Case: Radial

Mechanical Compatibility Criteria:

• Lens Style: Round with Domed Top
• Lens Size: 3mm class (2.90mm to 3.10mm Dia)
• Height: Maximum 6.20mm (accommodates PCB layout constraints)

Compliance Criteria:

• RoHS Status: RoHS3 Compliant or equivalent
• ECCN: EAR99
• HTSUS: 8541.41.0000

The identified substitute parts (264-7SYGT/S530-E2 and INL-3AYG30) maintain the core yellow-green spectral output and through-hole radial configuration. Both substitutes operate at 2V forward voltage with 20mA test current, representing a minor increase from the original 1.9V/10mA specification. Both substitutes are classified as active products with current manufacturing status and enhanced compliance certifications (RoHS3 and MSL 1).

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Mechanical and Electrical Compatibility):

The 264-7SYGT/S530-E2 from Everlight Electronics Co Ltd provides the closest form factor match with a 2.90mm lens diameter and 6.20mm maximum height. This part maintains the round domed-top lens configuration and radial through-hole package. The forward voltage increase from 1.9V to 2V and test current increase from 10mA to 20mA require circuit-level verification to confirm compatibility with existing current-limiting resistor networks. The part is ROHS3 compliant with MSL 1 rating, providing superior moisture handling compared to the obsolete original.

For Enhanced Performance Applications:

The INL-3AYG30 from Inolux offers increased luminous intensity (270mcd versus 100mcd) while maintaining the 3mm form factor and radial through-hole configuration. The 5.08mm maximum height accommodates standard PCB layouts. This part operates at 2V forward voltage with 20mA test current. ROHS3 compliance and MSL 1 rating provide long-term reliability advantages. The higher brightness output suits applications requiring improved visibility or extended viewing distance.

Compliance Considerations:

Both substitute parts carry ROHS3 certification and MSL 1 ratings, representing compliance improvements over the obsolete FHD3C64X-H (RoHS Compliant, MSL 2). Both parts maintain the EAR99 ECCN classification and 8541.41.0000 HTSUS code, ensuring regulatory consistency.

Frequently Asked Questions (FAQ)

Q: Can the FHD3C64X-H be directly replaced with 264-7SYGT/S530-E2 or INL-3AYG30?

A: Both parts are functionally compatible as yellow-green through-hole LEDs with matching spectral output (572-573nm dominant wavelength, 575nm peak). However, the forward voltage increases from 1.9V to 2V, and test current increases from 10mA to 20mA. Circuit verification is required to confirm that existing current-limiting resistors and power supply specifications accommodate these parameter changes.

Q: What are the key differences between the two substitute parts?

A: The 264-7SYGT/S530-E2 features a 2.90mm lens diameter with 6.20mm maximum height and delivers 125mcd brightness. The INL-3AYG30 features a 3mm lens diameter with 5.08mm maximum height and delivers 270mcd brightness. Both maintain round domed-top lens configuration and radial through-hole mounting. The INL-3AYG30 provides higher luminous intensity for applications requiring improved visibility.

Q: Are there mechanical fit concerns when substituting these parts?

A: The original FHD3C64X-H has a maximum height of 3.30mm. Both substitutes exceed this dimension (264-7SYGT/S530-E2 at 6.20mm, INL-3AYG30 at 5.08mm). PCB layout verification is necessary to confirm clearance above the component. Lens diameter differences (2.90mm for Everlight, 3mm for Inolux versus 3.10mm original) are within standard tolerance ranges for 3mm LED applications.

Q: What compliance advantages do the substitute parts offer?

A: Both substitute parts carry ROHS3 certification compared to the original RoHS Compliant designation. Both feature MSL 1 (Unlimited) moisture sensitivity ratings versus the original MSL 2 (1 Year), providing superior long-term storage and operational reliability. Both maintain EAR99 ECCN and 8541.41.0000 HTSUS classifications.

Q: Which substitute part should be selected for new designs?

A: Selection depends on application requirements. For space-constrained designs requiring minimal height increase, the INL-3AYG30 at 5.08mm maximum height is preferred. For applications requiring maximum brightness output, the INL-3AYG30 at 270mcd is superior. For applications with existing 2V/20mA circuit specifications, either part is suitable. Verify circuit compatibility with the 2V forward voltage specification before final selection.

Q: Are inventory considerations relevant to part selection?

A: The INL-3AYG30 has 3367 pieces in stock, the 264-7SYGT/S530-E2 has 986 pieces in stock. For high-volume production requirements, the INL-3AYG30 offers superior availability. Both parts are classified as active products with ongoing manufacturing support.
