Dialight 5505505 LED Circuit Board Indicator - Equivalent & Substitute Parts

Part Overview

The Dialight 5505505 is a 5mm red LED circuit board indicator with a clear domed lens, designed for through-hole right-angle mounting applications. This component features a 635nm peak wavelength, 20mA operating current, and 125mcd brightness rating. The part is classified as obsolete, necessitating identification of active equivalent alternatives for new designs and ongoing production requirements. Substitute parts must maintain electrical performance and mechanical compatibility within the specified parameter tolerances.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the Dialight 5505505 are classified into two categories based on parameter alignment:

Direct Substitutes (Dialight Series 550): Parts 5505505F and 5505507F maintain identical electrical and mechanical specifications as the main part. These components share the same color (red), wavelength (635nm), current rating (20mA), brightness (125mcd), viewing angle (24°), lens configuration (clear, round with domed top, 5mm T-1 3/4), voltage rating (2.2V), and mounting type (through hole, right angle). Both parts are active products with ROHS3 compliance and unlimited moisture sensitivity rating.

Similar Substitute (Cross-Manufacturer): Part HLMP-3750-L00B2 from Broadcom Limited matches the primary electrical and optical parameters: red color, 635nm wavelength, 20mA current, 125mcd brightness, 24° viewing angle, clear lens type, and through-hole right-angle mounting. The key parameter variance is the voltage rating of 1.9V compared to 2.2V. Lens style and size specifications are not provided for this part. This component is an active product with ROHS3 compliance.

Substitution eligibility is determined by matching: color, wavelength, current rating, brightness, viewing angle, lens type, mounting type, and voltage compatibility within circuit design tolerances.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement: Parts 5505505F and 5505507F are preferred substitutes for the obsolete Dialight 5505505. Both maintain complete electrical and mechanical parameter equivalence, including identical voltage rating (2.2V), lens specifications, and mounting configuration. Both parts are active products with ROHS3 compliance and unlimited moisture sensitivity rating, ensuring long-term availability and regulatory compliance for production applications.

For Cross-Manufacturer Substitution: The Broadcom HLMP-3750-L00B2 provides functional equivalence in optical and electrical performance with a 0.3V lower voltage rating (1.9V vs. 2.2V). This part is suitable for applications where circuit design accommodates the reduced forward voltage. The HLMP-3750-L00B2 is an active product with ROHS3 compliance. Lens style and size specifications are not provided; physical compatibility must be confirmed against PCB layout requirements.

Selection between Dialight direct substitutes (5505505F or 5505507F) should be based on packaging requirements and inventory availability. The cross-manufacturer option (HLMP-3750-L00B2) requires circuit design review to confirm voltage compatibility.

Frequently Asked Questions (FAQ)

Q: Can 5505505F and 5505507F be used interchangeably with the original 5505505?

A: Yes. Both parts maintain identical electrical specifications (20mA current, 2.2V voltage rating), optical characteristics (635nm wavelength, 125mcd brightness, 24° viewing angle), and mechanical configuration (5mm T-1 3/4 through-hole right-angle mounting with clear domed lens). Both are active products with ROHS3 compliance.

Q: What is the key difference between the Dialight substitutes and the Broadcom HLMP-3750-L00B2?

A: The primary difference is the forward voltage rating: Dialight parts are rated at 2.2V, while the Broadcom part is rated at 1.9V. All other electrical and optical parameters are equivalent. The Broadcom part does not specify lens style and size details.

Q: Is the Broadcom HLMP-3750-L00B2 a direct replacement?

A: The Broadcom part provides functional equivalence in optical output and current rating but operates at a lower forward voltage (1.9V vs. 2.2V). Circuit design must accommodate this voltage difference. Physical compatibility with PCB layout should be confirmed, as lens style and size specifications are not provided.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. Parts 5505505F, 5505507F, and HLMP-3750-L00B2 are all ROHS3 compliant. The original 5505505 RoHS status is not specified.

Q: What packaging options are available for the substitute parts?

A: Both Dialight substitutes (5505505F and 5505507F) are available in bulk packaging. The Broadcom HLMP-3750-L00B2 is also available in bulk packaging.

Q: Do all parts have the same moisture sensitivity rating?

A: Yes. The main part and all substitutes have MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions for storage and handling.
