Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the IS15ABFP4RGB is determined by strict equivalence across the following critical parameters:

• Circuit Configuration: SPST-NO contact type must be maintained
• Contact Rating: 0.1A @ 12VDC electrical specification
• Supply Voltage: 3.0 ~ 5.5VDC operating range
• Display Technology: Black and White FSTN Positive LCD
• LED Configuration: Red-Green-Blue backlighting
• Pixel Format: 36 x 24 resolution
• Mechanical Interface: Through Hole mounting with PC Pin termination
• Actuation Characteristics: 224gf operating force and 1.8mm travel range

The IS15BBFP4RGB meets all these criteria and qualifies as a direct substitute. This part maintains identical electrical and mechanical specifications while offering improved product status (Active vs. Obsolete) and extended operating temperature range.

Parameter Comparison

Engineering Selection Recommendations

The IS15BBFP4RGB is the qualified substitute for the obsolete IS15ABFP4RGB. Both components maintain identical electrical contact ratings, supply voltage specifications, display resolution, and mechanical interface requirements. The substitute part offers the following advantages:

• Active Product Status: IS15BBFP4RGB is currently in active production, ensuring long-term availability and supply chain continuity
• Extended Operating Temperature Range: -20°C ~ 60°C vs. 0°C ~ 40°C provides broader environmental compatibility
• RoHS3 Compliance: IS15BBFP4RGB meets RoHS3 requirements, supporting regulatory compliance requirements
• Improved Inventory: 1270 units available vs. 927 units for the obsolete part

Component selection should prioritize IS15BBFP4RGB for new designs and ongoing procurement. Existing systems using IS15ABFP4RGB may transition to the substitute part without circuit or mechanical redesign, provided operating temperature requirements remain within the specified range.

Frequently Asked Questions (FAQ)

Q: Can IS15BBFP4RGB directly replace IS15ABFP4RGB in existing assemblies?

A: Yes. Both parts maintain identical SPST-NO circuit configuration, 0.1A @ 12VDC contact rating, 3.0 ~ 5.5VDC supply voltage, 36 x 24 pixel display format, and Through Hole PC Pin mounting interface. No circuit or mechanical modifications are required for substitution.

Q: What are the differences between these two parts?

A: The primary differences are product status (Active vs. Obsolete), operating temperature range (-20°C ~ 60°C vs. 0°C ~ 40°C), LED forward current specifications (8-10.5mA vs. 10mA), and regulatory compliance (RoHS3 Compliant vs. not specified). Viewing area dimensions also differ slightly (17.0mm L x 13.0mm W vs. 15.0mm L x 10.8mm W).

Q: Are there packaging differences between these parts?

A: IS15ABFP4RGB is supplied in standard packaging, while IS15BBFP4RGB is available in Bulk packaging. Both use identical Through Hole PC Pin termination and are suitable for automated assembly processes.

Q: Which part should be specified for new designs?

A: IS15BBFP4RGB should be specified for all new designs. This part is in active production, offers extended operating temperature range, and meets RoHS3 compliance requirements.

Q: What is the viewing area difference between these parts?

A: IS15ABFP4RGB has a viewing area of 15.0mm L x 10.8mm W, while IS15BBFP4RGB has a viewing area of 17.0mm L x 13.0mm W. Both maintain identical 36 x 24 pixel resolution and identical face size (23.13mm L x 20.59mm W), ensuring mechanical compatibility in standard mounting applications.
