LED Circuit Board Indicator 5332H7 Equivalent & Substitute Parts

Part Overview

The VCC 5332H7 is a through-hole mounted LED circuit board indicator featuring a single yellow tinted lens. This component is classified as obsolete, making identification of equivalent substitute parts essential for ongoing production support and design continuity. The 5332H7 operates at 2.2V with a 20mA current rating and delivers 160mcd luminous intensity at a peak wavelength of 585nm. Due to its obsolete status, sourcing alternatives that maintain electrical and mechanical compatibility is necessary for system reliability and component availability.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete 5332H7 is determined by the following critical parameters:

Electrical Compatibility Parameters:

• Current rating: 20mA (exact match required)
• Voltage rating: 2.2V nominal (tolerance range 2.1V to 2.2V acceptable)
• Peak wavelength: 585nm yellow spectrum (583nm to 585nm acceptable)
• Configuration: Single LED (no multi-LED alternatives)

Mechanical Compatibility Parameters:

• Mounting type: Through hole (no surface mount alternatives)
• Lens type: Yellow-emitting (tinted or clear acceptable for yellow wavelength)
• Single component form factor

Compliance Parameters:

• RoHS3 compliance required
• REACH unaffected status required
• MSL 1 rating required

The Dialight 5615701802F meets all critical electrical and mechanical substitution criteria while maintaining active product status and full regulatory compliance.

Engineering Selection Recommendations

The Dialight 5615701802F is a qualified substitute for the obsolete VCC 5332H7 based on the following engineering criteria:

Electrical Equivalence: Both components operate at identical 20mA current ratings. The voltage differential of 0.1V (2.2V versus 2.1V) falls within standard LED forward voltage tolerance ranges and presents no functional incompatibility in typical circuit applications with current-limiting resistors.

Optical Compatibility: Peak wavelengths of 585nm and 583nm both fall within the yellow LED spectrum and are visually indistinguishable in circuit board indicator applications. The luminous intensity difference of 20mcd (160mcd versus 140mcd) represents a 12.5% reduction in brightness; this difference is acceptable for indicator applications where the primary function is status signaling rather than illumination intensity.

Mechanical Compatibility: Both components feature through-hole mounting with identical lead configurations, enabling direct PCB footprint compatibility without layout modifications.

Regulatory Compliance: The Dialight 5615701802F maintains ROHS3 compliance, REACH unaffected status, and MSL 1 rating, matching all regulatory requirements of the original component. The substitute's active product status ensures long-term availability and supply chain continuity.

Lens Consideration: The Dialight substitute features a clear lens with domed top geometry (5.00mm diameter) compared to the tinted lens of the original. Clear lenses provide equivalent color perception for yellow LEDs and offer superior light transmission characteristics.

Frequently Asked Questions (FAQ)

Q: Can the Dialight 5615701802F be used as a direct replacement for the VCC 5332H7 without circuit modifications?

A: Yes. The 20mA current rating, through-hole mounting, and forward voltage compatibility (2.1V versus 2.2V) enable direct substitution in existing PCB designs. Standard current-limiting resistor calculations remain valid across this voltage differential.

Q: What is the significance of the 20mcd luminous intensity difference?

A: The Dialight substitute delivers 140mcd compared to the original 160mcd. For circuit board indicator applications, this 12.5% reduction in brightness remains within acceptable visual perception thresholds and does not compromise indicator functionality. Applications requiring specific brightness levels should conduct visual validation testing.

Q: Are the lens types interchangeable?

A: The original features a tinted lens while the substitute features a clear lens with domed top. Both lens types transmit yellow light effectively. The clear lens of the substitute may provide slightly enhanced light transmission. Lens appearance differs visually; applications with specific aesthetic requirements should evaluate this difference.

Q: Does the wavelength difference (585nm versus 583nm) affect color perception?

A: No. Both wavelengths fall within the yellow LED spectrum and are visually indistinguishable to the human eye in indicator applications. The 2nm difference is negligible for color matching purposes.

Q: Is the Dialight 5615701802F compliant with the same regulatory standards?

A: Yes. The substitute maintains ROHS3 compliance, REACH unaffected status, and MSL 1 rating, matching all regulatory requirements of the original VCC 5332H7.

Q: What is the advantage of selecting an active product over the obsolete original?

A: The Dialight 5615701802F carries active product status, ensuring ongoing manufacturing, documented supply chain availability, and long-term component sourcing reliability. Obsolete components face eventual complete discontinuation and supply exhaustion.
