IS15ABFP4B Equivalent & Substitute Parts

Part Overview

The IS15ABFP4B is a programmable display switch from NKK Switches' SmartDisplay™ series, featuring an integrated LCD with SPST-NO contact configuration rated at 0.1A @ 12VDC. This through-hole mounted pushbutton combines a black and white FSTN positive display with white super bright LED indication. The product is currently obsolete, making identification of compatible substitute parts essential for ongoing system support and component procurement.

Key Parameters

Substitute Part Grouping Explanation

The IS15BBFP4RGB qualifies as a direct substitute based on the following critical parameters that remain constant across both parts:

Circuit configuration (SPST-NO), contact rating (0.1A @ 12VDC), supply voltage range (3.0 ~ 5.5VDC), mounting type (through hole), termination style (PC pin), operating force (224gf), travel range (1.8mm), face size (23.13mm L x 20.59mm W), and pixel format (36 x 24). These parameters define the functional and mechanical compatibility required for drop-in replacement within existing designs.

Parameter Comparison

Engineering Selection Recommendations

The IS15BBFP4RGB is the qualified substitute for the obsolete IS15ABFP4B. Both parts maintain identical electrical and mechanical specifications for circuit configuration, contact rating, supply voltage, mounting, and actuation characteristics. The substitute part is currently in active production status, ensuring long-term availability and supply chain continuity.

The IS15BBFP4RGB offers enhanced specifications in several areas: expanded operating temperature range (-20°C ~ 60°C versus 0°C ~ 40°C), larger viewing area (17.0mm L x 13.0mm W versus 15.0mm L x 10.8mm W), RGB LED capability with reduced forward current requirements, and ROHS3 compliance certification. These enhancements do not compromise compatibility with existing designs and provide improved environmental performance and regulatory compliance.

Frequently Asked Questions (FAQ)

Q: Can IS15BBFP4RGB directly replace IS15ABFP4B in existing designs?

A: Yes. Both parts share identical circuit configuration (SPST-NO), contact rating (0.1A @ 12VDC), supply voltage range (3.0 ~ 5.5VDC), mounting type (through hole), operating force (224gf), travel range (1.8mm), and face size (23.13mm L x 20.59mm W). No design modifications are required for mechanical or electrical integration.

Q: What are the key differences between these parts?

A: The substitute part features an expanded operating temperature range, larger viewing area, RGB LED capability with lower forward current consumption, and ROHS3 compliance. The original part provides white LED indication only. Both maintain identical switch functionality and contact specifications.

Q: Is the IS15BBFP4RGB available in the same packaging as IS15ABFP4B?

A: The IS15ABFP4B was supplied in standard packaging, while IS15BBFP4RGB is available in bulk packaging. Both use identical through-hole PC pin termination suitable for PCB assembly.

Q: Does the RGB LED capability of IS15BBFP4RGB affect compatibility?

A: No. The RGB LED is a functional enhancement that does not impact switch operation or electrical compatibility. Existing designs using single-color LED indication will function identically with the substitute part.

Q: What compliance certifications apply to the substitute part?

A: IS15BBFP4RGB carries ROHS3 compliance certification. Both parts are REACH unaffected and classified under ECCN EAR99.
