Key Parameters

Substitute Part Grouping Explanation

The IS15BAFP4CF qualifies as a direct substitute based on the following critical parameters that determine functional compatibility:

• Circuit Configuration: Both parts maintain SPST-NO switching topology
• Contact Rating: Identical 0.1A @ 12VDC electrical specification
• Supply Voltage: Both operate within 3.0 ~ 5.5VDC range
• Mounting Type: Both use through-hole mounting with PC pin termination
• Pixel Format: Both feature 36 x 24 pixel display resolution
• Face Size: Identical 23.13mm L x 20.59mm W dimensions
• Travel Range: Both specify 1.8mm travel distance
• Series: Both belong to NKK Switches SmartDisplay™ product line

The IS15BAFP4CF represents an active product with enhanced specifications in display technology (FSTN positive versus STN positive) and expanded operating temperature range (-20°C ~ 60°C versus 0°C ~ 40°C).

Parameter Comparison

Engineering Selection Recommendations

The IS15BAFP4CF is the appropriate substitute for the obsolete IS15AACP4CF based on the following factors:

Product Status: The IS15BAFP4CF maintains active product status with current manufacturing support, ensuring long-term availability and supply chain continuity for replacement and new applications.

Compliance & Certifications: The IS15BAFP4CF carries RoHS3 compliance certification, meeting current environmental and hazardous substance restrictions. Both parts maintain REACH Unaffected status and EAR99 export classification.

Electrical Compatibility: Identical circuit configuration (SPST-NO), contact rating (0.1A @ 12VDC), and supply voltage range (3.0 ~ 5.5VDC) ensure direct functional equivalence in switching applications.

Mechanical Compatibility: Matching face size (23.13mm L x 20.59mm W), mounting type (through hole), termination style (PC pin), and travel range (1.8mm) provide direct board-level compatibility without redesign.

Enhanced Operating Range: The IS15BAFP4CF extends the operating temperature range to -20°C ~ 60°C, providing broader environmental suitability compared to the original 0°C ~ 40°C specification.

Frequently Asked Questions (FAQ)

Q: Can IS15BAFP4CF be used as a direct replacement for IS15AACP4CF in existing designs?

A: Yes. Both parts share identical electrical specifications (SPST-NO, 0.1A @ 12VDC), mechanical dimensions (23.13mm L x 20.59mm W face size), and mounting configuration (through hole, PC pin termination). No circuit modifications are required.

Q: What are the differences between these parts?

A: The primary differences are display technology (yellow STN positive versus black and white FSTN positive), operating temperature range (0°C ~ 40°C versus -20°C ~ 60°C), operating force (224gf versus 173gf), and LED forward voltage specifications (2.1, 2.2VDC versus 2.2, 3.3VDC). The IS15BAFP4CF also carries RoHS3 compliance.

Q: Why is the IS15AACP4CF listed as obsolete?

A: The IS15AACP4CF has been discontinued by NKK Switches. The IS15BAFP4CF represents the active product line continuation within the SmartDisplay™ series with equivalent core functionality and enhanced specifications.

Q: Are there packaging differences between these parts?

A: The IS15AACP4CF is specified with standard packaging, while the IS15BAFP4CF is supplied in bulk packaging. Both maintain MSL 1 (Unlimited) moisture sensitivity classification.

Q: Will the lower operating force of IS15BAFP4CF (173gf vs 224gf) affect performance?

A: The operating force difference reflects design optimization in the substitute part. Both values fall within acceptable pushbutton actuation ranges for this product category. Selection should be based on application-specific tactile feedback requirements.

Q: Are both parts RoHS compliant?

A: The IS15BAFP4CF carries RoHS3 compliance certification. The IS15AACP4CF does not specify RoHS status in the provided data. Both maintain REACH Unaffected status.
