Parameter Comparison

Engineering Selection Recommendations

The IS15BSBFP4RGB is the direct substitute for the obsolete IS15SBFP4RGB. Selection of this substitute is supported by the following factors:

Product Status: The IS15BSBFP4RGB maintains Active product status, ensuring continued availability and manufacturer support. The original IS15SBFP4RGB is classified as Obsolete, necessitating transition to an active equivalent.

Regulatory Compliance: Both components maintain identical REACH and ECCN classifications (REACH Unaffected, EAR99), confirming equivalent regulatory standing. The substitute carries RoHS3 compliance certification.

Electrical and Mechanical Equivalence: All critical electrical parameters—circuit configuration, contact rating, supply voltage, and LED specifications—are identical. Mechanical parameters including mounting type, face size, pixel format, and travel range are fully matched.

Enhanced Operating Range: The IS15BSBFP4RGB provides an extended operating temperature range (-15°C ~ 50°C) compared to the original part (0°C ~ 40°C), offering improved performance envelope for temperature-sensitive applications.

Inventory Availability: The substitute part maintains robust stock levels (937 Pcs New Original In Stock) supporting immediate procurement for replacement and new design applications.

Frequently Asked Questions (FAQ)

Q: Can the IS15BSBFP4RGB be used as a direct replacement for IS15SBFP4RGB in existing designs?

A: Yes. The IS15BSBFP4RGB is a direct electrical and mechanical equivalent. All critical parameters—circuit configuration, contact rating, supply voltage, mounting type, face size, and display specifications—are identical. No design modifications are required.

Q: What is the primary difference between these two parts?

A: The IS15BSBFP4RGB is the active production equivalent of the obsolete IS15SBFP4RGB. The substitute offers an extended operating temperature range (-15°C ~ 50°C versus 0°C ~ 40°C) and carries RoHS3 compliance certification.

Q: Are there packaging differences between the main part and substitute?

A: The IS15SBFP4RGB is supplied in standard packaging, while the IS15BSBFP4RGB is supplied in Bulk packaging. Both use identical PC Pin termination and are suitable for through-hole mounting applications.

Q: Does the substitute part maintain the same display and LED specifications?

A: Yes. Both parts feature identical Black and White FSTN Positive display mode, 36 x 24 pixel format, 13.0mm x 10.7mm viewing area (main part) / 14.5mm x 11.8mm viewing area (substitute), and Red-Green-Blue LED color configuration.

Q: What compliance certifications apply to the substitute part?

A: The IS15BSBFP4RGB maintains REACH Unaffected and EAR99 ECCN classifications identical to the original part. Additionally, it carries RoHS3 compliance certification.

Q: Is the substitute suitable for applications requiring extended temperature operation?

A: Yes. The IS15BSBFP4RGB supports operation from -15°C to 50°C, providing a wider temperature envelope than the original part's 0°C to 40°C range, making it suitable for broader environmental conditions.
