Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the IS15DSBFP4RGB is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Manufacturer: NKK Switches
• Series: SmartDisplay™
• Circuit Configuration: SPST-NO
• Contact Rating: 0.1A @ 12VDC
• Supply Voltage: 4.9 ~ 5.1VDC
• Display Mode: Black and White, FSTN Positive
• LED Color: Red - Green - Blue
• Pixel Format: 64 x 32
• Mounting Type: Through Hole
• Termination Style: PC Pin
• Operating Temperature Range: -15°C ~ 50°C
• Moisture Sensitivity Level: 1 (Unlimited)

Allowable Variation Parameters:

• Viewing Area dimensions
• Face Size dimensions
• Operating Force (within functional tolerance)
• Travel Range (within functional tolerance)
• LED Forward Current and Voltage specifications
• Product Status (Active substitutes preferred for obsolete parts)
• Packaging configuration

The identified substitutes IS15EBFP4RGB and IS15ESBFP4RGB maintain full electrical and mechanical compatibility while offering active product status and enhanced compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

IS15ESBFP4RGB is the primary substitute for IS15DSBFP4RGB. This part maintains identical face size (19.0mm L x 18.0mm W), operating force (173gf), and travel range (1.8mm), ensuring direct mechanical and electrical compatibility. The IS15ESBFP4RGB carries Active product status with ROHS3 compliance certification, providing long-term availability and regulatory alignment for new designs.

IS15EBFP4RGB serves as an alternative substitute with expanded viewing area (17.0mm L x 13.0mm W) and increased travel range (4.5mm). This configuration is suitable for applications where enhanced display visibility and tactile feedback are beneficial. The higher operating force (204gf) and extended travel range represent functional variations that may require mechanical design consideration. ROHS3 compliance is maintained.

Both substitutes are manufactured by NKK Switches within the SmartDisplay™ series and maintain full electrical equivalence to the obsolete IS15DSBFP4RGB across all critical parameters including circuit configuration, contact rating, supply voltage, and display specifications.

Frequently Asked Questions (FAQ)

Q: Can IS15ESBFP4RGB directly replace IS15DSBFP4RGB without PCB modification?

A: Yes. The IS15ESBFP4RGB maintains identical face size (19.0mm L x 18.0mm W), mounting type (Through Hole), and termination style (PC Pin) as the original part. No PCB layout changes are required.

Q: What is the difference between IS15ESBFP4RGB and IS15EBFP4RGB?

A: Both parts are electrically equivalent. The primary differences are mechanical: IS15EBFP4RGB features a larger viewing area (17.0mm L x 13.0mm W versus 14.5mm L x 11.8mm W) and increased travel range (4.5mm versus 1.8mm). IS15ESBFP4RGB maintains the compact form factor of the original IS15DSBFP4RGB.

Q: Are the LED specifications identical across all three parts?

A: LED color configuration (Red - Green - Blue) and pixel format (64 x 32) are identical. Forward current and voltage specifications vary slightly: IS15DSBFP4RGB operates at 10, 10, 10mA with 2.1, 3.3, 3.3VDC, while both IS15ESBFP4RGB and IS15EBFP4RGB operate at 10, 8.5, 8mA with 2.0, 2.8, 2.8VDC. These variations remain within the 4.9 ~ 5.1VDC supply voltage specification.

Q: What is the inventory status for substitute parts?

A: IS15ESBFP4RGB has 1478 pieces in stock. IS15EBFP4RGB has 1103 pieces in stock. Both are classified as Active products with ROHS3 compliance.

Q: Are there packaging differences between the obsolete and substitute parts?

A: The original IS15DSBFP4RGB was supplied in standard packaging. Both substitutes are available in Bulk packaging configuration.

Q: Do the substitute parts meet the same regulatory requirements?

A: Yes. All three parts maintain REACH Unaffected status and Moisture Sensitivity Level 1 (Unlimited). The substitute parts additionally carry ROHS3 Compliant certification, providing enhanced regulatory alignment for current manufacturing standards.
