Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the IS15ABCP4CF is determined by strict equivalence in the following critical parameters: circuit configuration (SPST-NO), contact rating (0.1A @ 12VDC), supply voltage range (3.0 ~ 5.5VDC), mounting type (Through Hole), termination style (PC Pin), travel range (1.8mm), face size (23.13mm L x 20.59mm W), and pixel format (36 x 24).

The identified substitute parts maintain these core electrical and mechanical specifications. Variations in display mode technology (STN Positive versus FSTN Positive), LED color options, viewing area dimensions, operating force, and operating temperature range do not preclude substitution when the primary functional parameters remain constant.

Parameter Comparison

Engineering Selection Recommendations

Both IS15BAFP4CF and IS15BBFP4RGB are active production parts suitable for replacing the obsolete IS15ABCP4CF. The IS15BAFP4CF maintains the dual-color LED configuration (Red-Green) of the original part while offering ROHS3 compliance and an extended operating temperature range of -20°C ~ 60°C. The IS15BBFP4RGB provides tri-color LED capability (Red-Green-Blue) with identical ROHS3 compliance and temperature range.

Selection between these substitutes depends on application requirements for LED color functionality and operating force characteristics. The IS15BBFP4RGB operates at 224gf, matching the original part's operating force, while the IS15BAFP4CF operates at 173gf. Both parts maintain identical electrical ratings, mounting configuration, and mechanical envelope compatibility with the original design.

Frequently Asked Questions (FAQ)

Q: Can IS15BAFP4CF and IS15BBFP4RGB be used interchangeably with IS15ABCP4CF?

A: Both parts maintain the critical electrical and mechanical parameters required for substitution: SPST-NO circuit, 0.1A @ 12VDC contact rating, 3.0 ~ 5.5VDC supply voltage, Through Hole mounting, PC Pin termination, 1.8mm travel range, 23.13mm L x 20.59mm W face size, and 36 x 24 pixel format. Interchangeability is confirmed for these core specifications.

Q: What are the differences in display technology between the substitute parts and the original?

A: The IS15ABCP4CF features Yellow STN Positive display mode, while both IS15BAFP4CF and IS15BBFP4RGB use Black and White FSTN Positive display technology. This represents an advancement in display technology with improved contrast and viewing characteristics.

Q: How do the LED color options differ among these parts?

A: The IS15ABCP4CF provides Red-Green dual-color LED output. The IS15BAFP4CF maintains this Red-Green configuration. The IS15BBFP4RGB extends this to Red-Green-Blue tri-color capability, offering additional design flexibility for status indication applications.

Q: Are there compliance differences between the original and substitute parts?

A: The IS15ABCP4CF does not specify RoHS status. Both substitute parts, IS15BAFP4CF and IS15BBFP4RGB, are ROHS3 compliant, meeting current environmental and regulatory requirements.

Q: What is the operating temperature range difference?

A: The IS15ABCP4CF operates within 0°C ~ 40°C. Both substitute parts extend this range to -20°C ~ 60°C, providing broader thermal operating capability for diverse environmental applications.

Q: Does operating force affect substitution compatibility?

A: Operating force is not a substitution-limiting parameter for these parts. The IS15ABCP4CF and IS15BBFP4RGB both operate at 224gf, while IS15BAFP4CF operates at 173gf. Selection should be based on application tactile feedback requirements.
