MT212T-G-A Equivalent & Substitute Parts

Part Overview

The MT212T-G-A is a green diffused rectangular LED indicator manufactured by Marktech Optoelectronics, designed for through-hole mounting applications. This component features a 572nm dominant wavelength with 10mcd brightness rating and is suitable for discrete indication circuits requiring low-power green signaling. The MT212T-G-A is currently discontinued at DiGi Electronics, making identification of active equivalent parts essential for ongoing production and maintenance applications.

Key Parameters

Substitute Part Grouping Explanation

The MT212TB-G-A qualifies as a direct substitute for the MT212T-G-A based on the following critical parameters:

• Color and Wavelength: Both parts emit green light at 572nm dominant wavelength
• Optical Characteristics: Identical 10mcd brightness rating, diffused lens transparency, and 120° viewing angle
• Electrical Specifications: Matching 2.1V forward voltage and 20mA test current
• Physical Form Factor: Identical rectangular 4.00mm x 2.00mm lens dimensions with flat top style
• Mounting Configuration: Both use through-hole radial mounting with compatible package geometry
• Compliance: Both are RoHS compliant

The primary distinction is product status: MT212T-G-A is discontinued, while MT212TB-G-A remains active in production with higher inventory availability.

Parameter Comparison

Engineering Selection Recommendations

The MT212TB-G-A is the direct equivalent for MT212T-G-A applications. Selection should be based on the following factors:

Product Status: MT212TB-G-A is actively manufactured and stocked, ensuring supply chain continuity for new designs and production runs. MT212T-G-A discontinuation status eliminates it as a viable option for ongoing procurement.

Compliance Certifications: Both parts maintain RoHS compliance, satisfying regulatory requirements for electronic equipment in regulated markets.

Physical Compatibility: The maximum height difference of 0.25mm (5.20mm vs 5.45mm) falls within typical PCB design tolerances for through-hole components and does not impact circuit board layout or assembly processes.

Electrical Equivalence: Identical forward voltage, test current, and optical output characteristics ensure direct functional replacement without circuit modification.

Frequently Asked Questions (FAQ)

Q: Can MT212TB-G-A replace MT212T-G-A in existing designs?

A: Yes. Both parts share identical electrical specifications (2.1V forward voltage, 20mA test current), optical characteristics (572nm wavelength, 10mcd brightness, 120° viewing angle), and physical form factor (4.00mm x 2.00mm rectangular lens, through-hole radial mounting). The 0.25mm height difference does not affect PCB compatibility.

Q: What is the primary reason for substitution?

A: MT212T-G-A is discontinued at DiGi Electronics. MT212TB-G-A is the active production equivalent with identical performance specifications and higher inventory availability.

Q: Are there packaging differences between these parts?

A: Yes. MT212T-G-A is supplied in tape packaging, while MT212TB-G-A is supplied in bulk packaging. This distinction affects order quantities and handling but does not impact component functionality or performance.

Q: Do both parts meet RoHS compliance requirements?

A: Yes. Both MT212T-G-A and MT212TB-G-A are RoHS compliant, meeting environmental and regulatory standards for electronic component manufacturing.

Q: Is circuit redesign required when switching from MT212T-G-A to MT212TB-G-A?

A: No. Identical electrical and optical specifications eliminate the need for circuit modification. Direct pin-for-pin and functional replacement is applicable.
