COM-15140 Rotary Encoder Equivalent & Substitute Parts

Part Overview

The COM-15140 is an incremental rotary encoder with 24 pulses per revolution, featuring integrated illumination (red/green) and a built-in switch. This component is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing design support and procurement planning. The COM-15141 serves as the direct substitute, offering identical core electrical and mechanical specifications with the distinction of RGB illumination capability and active product status.

Substitute Part Grouping Explanation

The COM-15141 qualifies as a direct substitute for the COM-15140 based on matching critical electrical and mechanical parameters:

• Encoder Type & Output: Both are incremental encoders with Gray Code (Absolute) output
• Resolution: Identical 24 pulses per revolution
• Supply Voltage: Both operate at 5V
• Mechanical Interface: Matching 6mm flatted end actuator, detent mechanism, and built-in switch
• Mounting & Orientation: Identical PCB through-hole mounting in vertical orientation with PC pin termination
• Compliance: Both meet ROHS3 requirements and share identical MSL rating

The primary distinction is illumination type (red/green vs. RGB) and product lifecycle status (obsolete vs. active).

Parameter Comparison

Engineering Selection Recommendations

The COM-15141 is the appropriate substitute for COM-15140 applications. Both components share identical electrical performance characteristics, mechanical interfaces, and regulatory compliance certifications. The COM-15141 offers the advantage of active product status, ensuring continued availability and supply chain stability. The RGB illumination enhancement in COM-15141 provides expanded color capability while maintaining full backward compatibility with existing 5V control circuits and PCB mounting footprints. Selection of COM-15141 eliminates obsolescence risk associated with the COM-15140.

Frequently Asked Questions (FAQ)

Q: Can COM-15141 directly replace COM-15140 in existing designs? A: Yes. Both encoders share identical electrical specifications (5V supply, 24 PPR Gray Code output), mechanical dimensions (6mm flatted actuator), and mounting interfaces (PCB through-hole, vertical orientation). The RGB illumination in COM-15141 is a functional enhancement that does not affect core encoder operation.

Q: What is the primary reason for substitution? A: COM-15140 is classified as obsolete. COM-15141 provides equivalent functionality with active product status and improved availability.

Q: Are there differences in illumination control? A: COM-15140 features red/green illumination, while COM-15141 provides RGB illumination. Both are integrated into the encoder assembly. Circuit-level control requirements may differ based on specific illumination implementation; refer to component datasheets for pin configuration details.

Q: Do both parts meet the same compliance standards? A: Yes. Both COM-15140 and COM-15141 are ROHS3 compliant with MSL rating of 1 (Unlimited). Both carry identical ECCN (EAR99) and HTSUS (8543.70.4500) classifications.

Q: What is the packaging difference? A: COM-15140 packaging is unspecified in available data. COM-15141 is supplied in bulk packaging. Confirm packaging requirements with supplier specifications for procurement planning.
