Key Parameters

Substitute Part Grouping Explanation

Substitution of the IS15ABCP4EF is based on strict equivalence of electrical and mechanical parameters within the SmartDisplay™ series. The primary substitute, IS15BBFP4RGB, maintains compatibility through the following critical parameters:

• Identical circuit configuration (SPST-NO)
• Identical contact rating (0.1A @ 12VDC)
• Identical supply voltage range (3.0 ~ 5.5VDC)
• Identical mounting type (Through Hole) and termination style (PC Pin)
• Identical operating force (224gf) and travel range (1.8mm)
• Identical face size (23.13mm L x 20.59mm W)
• Identical pixel format (36 x 24)

Differences exist in display technology, LED color configuration, and operating temperature range, but these do not prevent functional substitution in applications where the IS15ABCP4EF specifications are met.

Parameter Comparison

Engineering Selection Recommendations

The IS15BBFP4RGB serves as the active production substitute for the obsolete IS15ABCP4EF. Selection between these parts should be based on the following criteria:

For IS15ABCP4EF (Obsolete): Use only when existing inventory is available or when legacy system documentation specifically requires this exact part number. Current stock is 744 pieces.

For IS15BBFP4RGB (Active): Recommended for new designs and ongoing production. This part is currently in active production status with 1,270 pieces in stock. It maintains all critical electrical and mechanical parameters while offering an extended operating temperature range (-20°C ~ 60°C versus 0°C ~ 40°C) and RoHS3 compliance. The FSTN display technology and RGB LED configuration provide enhanced visual capabilities compared to the original STN yellow display.

Both parts carry identical REACH and ECCN classifications, confirming regulatory equivalence for export and environmental compliance purposes.

Frequently Asked Questions (FAQ)

Q: Can IS15BBFP4RGB directly replace IS15ABCP4EF in existing applications?

A: Yes. Both parts share identical electrical ratings (0.1A @ 12VDC, SPST-NO), mechanical dimensions (face size 23.13mm L x 20.59mm W), and mounting specifications (Through Hole, PC Pin termination). The substitute operates within the same supply voltage range (3.0 ~ 5.5VDC) and maintains identical pixel format (36 x 24) and operating force (224gf).

Q: What are the key differences between these parts?

A: The primary differences are display technology (STN yellow versus FSTN black and white), LED color options (yellow-green versus red-green-blue), viewing area dimensions (15.0mm x 10.8mm versus 17.0mm x 13.0mm), and operating temperature range (0°C ~ 40°C versus -20°C ~ 60°C). The substitute also includes RoHS3 compliance.

Q: Why is IS15ABCP4EF marked as obsolete?

A: The IS15ABCP4EF has been discontinued by NKK Switches. The IS15BBFP4RGB represents the current production equivalent within the SmartDisplay™ series.

Q: Are there packaging differences between these parts?

A: The IS15ABCP4EF is supplied in standard packaging, while IS15BBFP4RGB is supplied in bulk packaging. Both maintain identical moisture sensitivity level (MSL 1 - Unlimited).

Q: Do both parts meet the same regulatory standards?

A: Yes. Both parts are REACH Unaffected and classified as EAR99 for export control purposes. The IS15BBFP4RGB additionally carries RoHS3 compliance certification.
