Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the BLC2021-AL-FB are qualified based on strict electrical and mechanical compatibility criteria. All substitute parts maintain identical specifications across the following critical parameters:

• Number of Characters: 40
• Display Format: 20 x 2
• Display Type: LCD - Monochrome
• Character Size: 5.55mm H x 3.20mm W
• Outline Dimensions: 116.00mm x 37.00mm x 28.98mm
• Viewing Area: 83.00mm x 18.60mm
• Voltage - Supply: 9V ~ 15V
• Interface: I2C, RS-232, TTL
• Background Color: Black
• Moisture Sensitivity Level: 1 (Unlimited)

The primary differentiation among substitute parts is the text color variant, which does not affect electrical or mechanical compatibility. All substitute parts are manufactured by Matrix Orbital and share the base product number BLC2021. Substitute parts BLC2021-AL-FA, BLC2021-AL-FG, BLC2021-AL-IY, and BLC2021-AL-R are all listed with Active product status and RoHS compliance.

Parameter Comparison

Engineering Selection Recommendations

The BLC2021-AL-FB is obsolete and no longer in active production. All four substitute parts (BLC2021-AL-FA, BLC2021-AL-FG, BLC2021-AL-IY, BLC2021-AL-R) are manufactured by Matrix Orbital with Active product status and RoHS compliance certification. These parts are electrically and mechanically equivalent to the BLC2021-AL-FB, differing only in text color display characteristics.

For new designs or component replacement, selection among the substitute parts should be based on the required text color for display visibility and application requirements. All substitute parts maintain identical electrical specifications, mechanical dimensions, and interface compatibility with the original BLC2021-AL-FB.

Frequently Asked Questions (FAQ)

Q: Can BLC2021-AL-FA, BLC2021-AL-FG, BLC2021-AL-IY, and BLC2021-AL-R be used interchangeably with BLC2021-AL-FB?

A: Yes. All substitute parts share identical electrical specifications, mechanical dimensions, character count, display format, and interface options. The only difference is the text color variant. Interchangeability depends on whether the application requires a specific text color for visibility or user interface requirements.

Q: What is the primary difference between the BLC2021-AL-FB and its substitutes?

A: The BLC2021-AL-FB features blue text on a black background. Substitute parts offer alternative text colors: amber (BLC2021-AL-FA), green (BLC2021-AL-FG), yellow (BLC2021-AL-IY), and red (BLC2021-AL-R). All other specifications remain identical.

Q: Are the substitute parts RoHS compliant?

A: Yes. BLC2021-AL-FA, BLC2021-AL-FG, BLC2021-AL-IY, and BLC2021-AL-R are all RoHS compliant. The original BLC2021-AL-FB does not specify RoHS status.

Q: Do the substitute parts support the same interfaces as the BLC2021-AL-FB?

A: Yes. All substitute parts support I2C, RS-232, and TTL interfaces, identical to the BLC2021-AL-FB.

Q: What are the packaging options for substitute parts?

A: All substitute parts are available in Bulk packaging.

Q: Are there any differences in operating voltage between the BLC2021-AL-FB and substitute parts?

A: No. All parts operate within the same 9V to 15V supply voltage range.
