IS15SBCP4CF Equivalent & Substitute Parts

Part Overview

The IS15SBCP4CF is a programmable display switch from NKK Switches' SmartDisplay™ series, featuring an integrated LCD with SPST-NO switching capability rated at 0.1A @ 12VDC. This through-hole mounted pushbutton combines a yellow STN positive display with red-green super bright LEDs in a compact 19.0mm × 18.0mm form factor.

The IS15SBCP4CF is classified as obsolete. Locating equivalent substitute parts is necessary to maintain design continuity, ensure component availability for production, and support long-term system maintenance where this model is no longer actively manufactured.

Substitute Part Grouping Explanation

The IS15BSBFP4RGB qualifies as a direct substitute for the IS15SBCP4CF based on the following critical parameters:

Electrical Compatibility:

• Identical circuit configuration (SPST-NO)
• Identical contact rating (0.1A @ 12VDC)
• Identical supply voltage range (3.0 ~ 5.5VDC)
• Identical switch function (Off-Mom)

Mechanical Compatibility:

• Identical mounting type (Through Hole)
• Identical termination style (PC Pin)
• Identical face size (19.0mm L × 18.0mm W)
• Identical pixel format (36 × 24)
• Identical travel range (1.8mm)

Environmental & Regulatory Compliance:

• Identical moisture sensitivity level (MSL 1)
• Identical REACH status (REACH Unaffected)
• Both classified under same ECCN (EAR99)

The IS15BSBFP4RGB represents an active product within the same SmartDisplay™ series, offering enhanced specifications in display technology (FSTN vs. STN), expanded operating temperature range, and improved LED efficiency while maintaining full electrical and mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

The IS15BSBFP4RGB is the appropriate substitute for the obsolete IS15SBCP4CF. Selection is based on:

Product Availability: The IS15SBCP4CF is obsolete and no longer manufactured. The IS15BSBFP4RGB is an active product with confirmed inventory availability.

Regulatory Compliance: Both parts maintain identical REACH compliance status (REACH Unaffected) and ECCN classification (EAR99), ensuring no regulatory barriers to substitution.

Functional Equivalence: Electrical specifications are identical across all critical parameters: circuit type, contact rating, supply voltage, and switching function. Mechanical compatibility is confirmed through identical mounting, termination, face dimensions, and pixel format.

Enhanced Specifications: The substitute part offers expanded operating temperature range (-15°C ~ 50°C vs. 0°C ~ 40°C) and improved display technology (FSTN vs. STN), providing superior performance characteristics for the same electrical interface.

Frequently Asked Questions (FAQ)

Q: Can IS15BSBFP4RGB directly replace IS15SBCP4CF in existing designs?

A: Yes. Both parts share identical electrical ratings (0.1A @ 12VDC, SPST-NO), supply voltage (3.0 ~ 5.5VDC), mechanical mounting (Through Hole, PC Pin), and physical dimensions (19.0mm × 18.0mm face size). No circuit modifications are required.

Q: What are the key differences between these parts?

A: The substitute features FSTN display technology versus STN, expanded operating temperature range (-15°C ~ 50°C vs. 0°C ~ 40°C), reduced operating force (173gf vs. 224gf), and RGB LED capability versus red-green only. These represent enhancements to the original design.

Q: Are there any compliance or certification concerns with substitution?

A: No. Both parts maintain identical REACH compliance status and ECCN classification. Moisture sensitivity level (MSL 1) is identical, confirming equivalent handling and storage requirements.

Q: What is the inventory status of each part?

A: IS15SBCP4CF is obsolete with 1018 units in stock. IS15BSBFP4RGB is an active product with 937 units in stock.

Q: Does the reduced operating force of the substitute affect functionality?

A: The operating force difference (173gf vs. 224gf) reflects design optimization in the active product. Both values fall within acceptable pushbutton actuation ranges for this product category and do not impact electrical switching performance.
