Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the IS15ABCP4E is determined by strict alignment with the following core electrical and mechanical parameters:

• Circuit Configuration: SPST-NO topology must be maintained
• Contact Rating: 0.1A @ 12VDC minimum requirement
• Supply Voltage Range: 3.0 ~ 5.5VDC compatibility
• Mounting Architecture: Through hole mounting with PC pin termination
• Mechanical Compatibility: Operating force of 224gf and 1.8mm travel range
• Face Dimensions: 23.13mm L x 20.59mm W envelope constraint
• Pixel Format: 36 x 24 display resolution

The IS15BBFP4RGB meets all mandatory substitution criteria. While display technology and LED color specifications differ, the electrical switching characteristics, mechanical form factor, and interface parameters remain functionally equivalent for component replacement applications.

Parameter Comparison

Engineering Selection Recommendations

The IS15BBFP4RGB is the qualified substitute for the obsolete IS15ABCP4E based on the following engineering criteria:

Product Status: The IS15BBFP4RGB maintains active product status with NKK Switches, ensuring ongoing availability and manufacturing support compared to the obsolete IS15ABCP4E.

Regulatory Compliance: The IS15BBFP4RGB carries RoHS3 compliance certification, providing enhanced environmental and material restriction alignment for modern manufacturing and end-use applications. Both parts maintain REACH unaffected status and EAR99 export classification.

Electrical Equivalence: Identical SPST-NO circuit configuration, contact rating (0.1A @ 12VDC), and supply voltage range (3.0 ~ 5.5VDC) ensure direct functional replacement without circuit redesign.

Mechanical Compatibility: Matching face dimensions (23.13mm L x 20.59mm W), operating force (224gf), travel range (1.8mm), and through-hole PC pin termination enable direct board-level substitution.

Extended Operating Range: The IS15BBFP4RGB supports -20°C ~ 60°C operating temperature, exceeding the IS15ABCP4E specification of 0°C ~ 40°C, providing broader environmental tolerance for diverse deployment scenarios.

Frequently Asked Questions (FAQ)

Q: Can the IS15BBFP4RGB replace the IS15ABCP4E in existing designs without PCB modification?

A: Yes. Both components share identical face dimensions (23.13mm L x 20.59mm W), through-hole mounting architecture, and PC pin termination. Direct board-level substitution is mechanically and electrically compatible.

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

A: The primary differences are display technology (yellow STN positive versus black and white FSTN positive), LED color (yellow super bright versus red-green-blue), operating temperature range (-20°C ~ 60°C versus 0°C ~ 40°C), and product status (active versus obsolete). Electrical switching characteristics and mechanical form factors remain identical.

Q: Are the LED specifications interchangeable?

A: The LED specifications differ in color output and forward current/voltage ratings. The IS15ABCP4E provides yellow indication at 15mA forward current and 2.2VDC forward voltage. The IS15BBFP4RGB provides RGB indication with forward currents of 10mA (red), 8.5mA (green), and 8mA (blue) at respective forward voltages of 2.0VDC, 2.8VDC, and 2.8VDC. LED drive circuitry may require adjustment to accommodate these parameter differences.

Q: Does the IS15BBFP4RGB meet current regulatory requirements?

A: Yes. The IS15BBFP4RGB carries RoHS3 compliance certification and maintains REACH unaffected status, meeting current environmental and material restriction requirements for manufacturing and distribution.

Q: What is the pixel format compatibility between these parts?

A: Both components maintain identical 36 x 24 pixel format, ensuring display resolution and information presentation consistency across substitution.

Q: Are there packaging differences between the main part and substitute?

A: The IS15ABCP4E is supplied in standard packaging, while the IS15BBFP4RGB is supplied in bulk packaging. This distinction affects procurement and inventory management but does not impact component functionality or performance.
