Substitute Part Grouping Explanation

Substitution eligibility for the IS15DBFP4RGB is determined by strict equivalence across the following critical parameters:

Electrical Compatibility:

• SPST-NO circuit configuration
• 0.1A @ 12VDC contact rating
• 4.9 ~ 5.1VDC supply voltage range
• Red-Green-Blue LED color capability

Mechanical Compatibility:

• Through Hole mounting type
• PC Pin termination style
• 4.5mm travel range
• 204gf operating force
• -15°C ~ 50°C operating temperature range

Display Specifications:

• 64 x 32 pixel format
• Black and White FSTN Positive display mode

The IS15EBFP4RGB meets all substitution criteria as a direct equivalent within the SmartDisplay™ series, maintaining identical electrical ratings, mechanical form factor, and display specifications.

Parameter Comparison

Engineering Selection Recommendations

The IS15EBFP4RGB is the direct substitute for the obsolete IS15DBFP4RGB. Both components share identical electrical specifications, mechanical interfaces, and display characteristics. The substitute part is currently in active production status, ensuring availability for new procurement and system support.

The IS15EBFP4RGB carries ROHS3 compliance certification, providing regulatory advantage over the original part. Both components maintain REACH Unaffected status and EAR99 export classification.

The viewing area differs between the two parts (IS15DBFP4RGB: 15.0mm L x 10.8mm W; IS15EBFP4RGB: 17.0mm L x 13.0mm W), representing an increase in visible display dimensions. The face size remains constant at 23.13mm L x 20.59mm W, maintaining mechanical compatibility with existing mounting interfaces.

LED forward current and voltage specifications show minor variations: the substitute part operates at reduced current levels (10mA, 8.5mA, 8mA versus 10mA, 10mA, 10mA) with correspondingly lower forward voltages (2.0V, 2.8V, 2.8V versus 2.1V, 3.3V, 3.3V). These differences reflect component optimization and do not affect functional compatibility within the specified supply voltage range.

Frequently Asked Questions (FAQ)

Q: Can IS15EBFP4RGB directly replace IS15DBFP4RGB in existing designs?

A: Yes. Both components maintain identical SPST-NO circuit configuration, 0.1A @ 12VDC contact rating, 4.9 ~ 5.1VDC supply voltage, Through Hole mounting, and PC Pin termination. Electrical and mechanical interfaces are fully compatible.

Q: What is the significance of the viewing area difference?

A: The IS15EBFP4RGB provides a larger viewing area (17.0mm L x 13.0mm W versus 15.0mm L x 10.8mm W) while maintaining the same face size (23.13mm L x 20.59mm W). This represents improved display visibility without affecting mounting compatibility or mechanical form factor.

Q: Are there compliance differences between the two parts?

A: The IS15EBFP4RGB carries ROHS3 compliance certification. Both parts maintain REACH Unaffected status and EAR99 export classification. The substitute part offers enhanced regulatory compliance for new applications.

Q: Why do LED specifications differ between the parts?

A: The IS15EBFP4RGB operates at reduced LED forward current (8-10mA versus 10mA across all channels) and lower forward voltages (2.0-2.8V versus 2.1-3.3V). These optimizations maintain full RGB color capability within the 4.9 ~ 5.1VDC supply voltage specification and do not affect functional performance.

Q: What is the packaging difference?

A: IS15DBFP4RGB is supplied in standard packaging, while IS15EBFP4RGB is available in bulk packaging. Both represent the same component with identical electrical and mechanical specifications.

Q: Is the IS15EBFP4RGB suitable for temperature-sensitive applications?

A: Both parts operate across the identical temperature range of -15°C ~ 50°C. Component selection should be based on specific application temperature requirements within this range.
