Substitute Part Grouping Explanation

Substitution eligibility for the IS15DBFP4RGB-09YN is determined by strict alignment of the following critical parameters:

• Manufacturer & Series: Must be NKK Switches SmartDisplay™ series to ensure firmware compatibility and mechanical fit
• Circuit & Function: SPST-NO configuration with Off-Mom switch function required
• Electrical Ratings: Contact rating of 0.1A @ 12VDC and supply voltage of 4.9 ~ 5.1VDC must be maintained
• Display Specifications: 64 x 32 pixel resolution, Black and White FSTN Positive display mode, and RGB LED capability required
• Mechanical Interface: Through-hole mounting with PC pin termination mandatory for PCB compatibility
• Operating Environment: Temperature range -15°C ~ 50°C and MSL 1 rating required
• Compliance: ROHS3 compliance required for regulatory alignment

The IS15EBFP4RGB-09YN meets all substitution criteria as a direct equivalent from the same manufacturer and series, with identical electrical and display specifications.

Parameter Comparison

Engineering Selection Recommendations

The IS15EBFP4RGB-09YN is the direct substitute for the obsolete IS15DBFP4RGB-09YN. Both components maintain identical electrical specifications, circuit configuration, display resolution, and compliance certifications. The substitute part is currently in active production status with confirmed inventory availability.

Differences in viewing area dimensions, operating force, travel range, and LED current/voltage characteristics are secondary parameters that do not affect functional substitution within the defined electrical and mechanical interface requirements. These variations reflect design evolution within the SmartDisplay™ series while maintaining core compatibility.

Selection of the IS15EBFP4RGB-09YN ensures regulatory compliance through ROHS3 certification and provides access to an actively supported component with established supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can the IS15EBFP4RGB-09YN be used as a direct replacement for IS15DBFP4RGB-09YN in existing designs?

A: Yes. Both components share identical electrical ratings (0.1A @ 12VDC), circuit configuration (SPST-NO), display specifications (64x32 RGB LCD), mounting interface (through-hole PC pin), and operating temperature range (-15°C ~ 50°C). The substitute part maintains full functional compatibility.

Q: What are the physical differences between these two parts?

A: The IS15EBFP4RGB-09YN features a larger viewing area (17.0mm L x 13.0mm W versus 15.0mm L x 10.8mm W), increased operating force (204gf versus 173gf), and extended travel range (4.5mm versus 1.8mm). Face size remains identical at 23.13mm L x 20.59mm W. These differences may affect user interface feel and visual display area but do not impact electrical compatibility.

Q: Are there any compliance or certification differences?

A: Both parts are ROHS3 compliant with MSL 1 (Unlimited) rating. No compliance differences exist between the main part and substitute.

Q: What is the inventory status of the substitute part?

A: The IS15EBFP4RGB-09YN is in active production with 1593 pieces currently in stock, compared to the obsolete IS15DBFP4RGB-09YN with 824 pieces remaining inventory.

Q: Do the LED current and voltage differences affect circuit design?

A: LED forward current and voltage specifications differ slightly between parts. Circuit designs must accommodate the IS15EBFP4RGB-09YN specifications (10, 8.5, 8mA for R, G, B channels at 2.0, 2.8, 2.8VDC respectively) to ensure proper LED operation and color balance.
