LED Circuit Board Indicator Bar 104990099 Equivalent & Substitute Parts

Part Overview

The Seeed Technology Co., Ltd. model 104990099 is a LED Circuit Board Indicator Bar designed for single DIP configuration applications. This component features a blue diffused lens with a square flat-top design and 15.00mm lens size, rated for 140mA operation. The product is classified as obsolete, making identification of functionally equivalent substitute components essential for ongoing design support, maintenance, and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 104990099 is based on strict alignment of the following parameters:

Critical Matching Parameters:

• Configuration: Bar - Single, DIP (electrical and mechanical interface compatibility)
• Current Rating: 140mA (operational electrical specification)
• Lens Size: 15.00mm (physical footprint and mounting hole compatibility)
• Lens Style: Square with Flat Top (mechanical form factor)

Secondary Compatibility Parameters:

• Moisture Sensitivity Level: 1 (Unlimited) (handling and storage equivalence)
• ECCN Classification: EAR99 (regulatory compliance equivalence)

The substitute part XEMG29DX from SunLED meets all critical matching parameters. While the color differs (green versus blue) and the lens type differs (diffused tinted versus diffused white), these are application-specific optical characteristics that do not affect mechanical or primary electrical substitution compatibility. The voltage rating (2.2V) and millicandela rating (20mcd) are provided for the substitute but were not specified for the main part, therefore these parameters do not constrain substitution eligibility.

Parameter Comparison

Engineering Selection Recommendations

The XEMG29DX from SunLED is classified as an active product with current manufacturing support, whereas the 104990099 is obsolete. Both components share identical critical electrical and mechanical parameters: Bar - Single DIP configuration, 140mA current rating, 15.00mm square flat-top lens size, and MSL 1 (Unlimited) moisture sensitivity classification.

Both parts carry EAR99 ECCN classification, confirming equivalent regulatory compliance status. The XEMG29DX provides additional documented specifications including 2.2V voltage rating, 20mcd millicandela rating, and ROHS3 compliance certification, which were not provided for the obsolete 104990099.

Selection of XEMG29DX as a substitute is supported by product status (active versus obsolete), regulatory equivalence, and complete parameter alignment on all critical substitution criteria. The difference in color (green versus blue) and lens tint (tinted versus white diffusion) represents an application-specific optical characteristic that must be evaluated within the context of the end-use application.

Frequently Asked Questions (FAQ)

Q: Can XEMG29DX directly replace 104990099 in existing circuit board designs?

A: The XEMG29DX meets all critical mechanical and electrical substitution parameters: identical DIP configuration, 140mA current rating, and 15.00mm square flat-top lens size. Direct PCB footprint compatibility is confirmed. However, the green color output differs from the original blue, which may affect visual indication functionality depending on application requirements.

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

A: The primary differences are: (1) manufacturer (Seeed versus SunLED), (2) product status (obsolete versus active), (3) color (blue versus green), and (4) lens tint specification (white diffusion versus tinted diffusion). All electrical and mechanical parameters are identical.

Q: Is the XEMG29DX RoHS compliant?

A: Yes, XEMG29DX is ROHS3 compliant and REACH unaffected. The original 104990099 RoHS status was not provided in the available documentation.

Q: What is the packaging difference?

A: The 104990099 packaging specification was not provided. The XEMG29DX is supplied in tube packaging.

Q: Are there any voltage or current derating considerations?

A: Both components are rated for 140mA operation. The XEMG29DX specifies 2.2V forward voltage; the 104990099 voltage rating was not provided. Verify voltage compatibility with your circuit design requirements.

Q: Can I use XEMG29DX if my application specifically requires blue indication?

A: No. The XEMG29DX produces green light output. If blue indication is functionally required, this substitute is not appropriate for your application. Alternative blue-emitting components with matching DIP configuration and 15.00mm lens size must be sourced.
