RPM6933 Equivalent & Substitute Parts

Part Overview

The RPM6933 is a remote receiver sensor manufactured by Rohm Semiconductor, designed to detect infrared signals at a center frequency of 33.0kHz with a sensing distance of 16 meters. This component is classified as obsolete, making identification of suitable substitute parts essential for ongoing system maintenance and new design implementations. The part operates within a 4.5V to 5.5V supply range and draws 1.5mA during operation, featuring through-hole mounting in a side-view orientation.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RPM6933 is determined by the following critical parameters:

• B.P.F. Center Frequency: 33.0kHz (must match exactly for signal compatibility)
• Mounting Type: Through Hole (mechanical compatibility requirement)
• Orientation: Side View (PCB layout compatibility)
• Voltage - Supply: 4.5V ~ 5.5V (power supply compatibility)
• Category: Optical Sensors - Remote Receiver (functional equivalence)

The TSOP2133 from Vishay Semiconductor Opto Division satisfies all substitution criteria. Both components operate at the identical 33.0kHz center frequency, share through-hole mounting with side-view orientation, and accept the same 4.5V to 5.5V supply voltage range. These parameters ensure direct functional compatibility in existing circuit designs.

Engineering Selection Recommendations

The TSOP2133 is the qualified substitute for the RPM6933 based on the following engineering criteria:

• Both components maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for new designs and replacements.
• The TSOP2133 is actively manufactured by Vishay Semiconductor Opto Division, ensuring long-term availability and supply chain stability compared to the obsolete RPM6933.
• Electrical parameters are fully compatible: identical 33.0kHz center frequency, matching 4.5V to 5.5V supply voltage, and lower current consumption (1.1mA versus 1.5mA).
• Mechanical compatibility is confirmed through identical through-hole mounting and side-view orientation, allowing direct PCB footprint substitution.
• The TSOP2133 provides extended sensing distance (35m versus 16m) and defined operating temperature range (-25°C to 85°C), offering enhanced performance margins for system reliability.

Frequently Asked Questions (FAQ)

Q: Can the TSOP2133 be used as a direct replacement for the RPM6933 in existing designs?

A: Yes. Both components share identical B.P.F. center frequency (33.0kHz), supply voltage range (4.5V to 5.5V), mounting type (through-hole), and orientation (side-view). The TSOP2133 can be substituted without circuit modifications.

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

A: The TSOP2133 offers extended sensing distance (35m versus 16m), lower supply current (1.1mA versus 1.5mA), and a defined operating temperature range (-25°C to 85°C). The RPM6933 operating temperature is not specified. The TSOP2133 is actively manufactured; the RPM6933 is obsolete.

Q: Are there any packaging differences between the RPM6933 and TSOP2133?

A: Both components use through-hole mounting with side-view orientation. The TSOP2133 is supplied in tube packaging. Mechanical compatibility is confirmed for direct PCB substitution.

Q: Do both components meet the same compliance standards?

A: Yes. Both the RPM6933 and TSOP2133 are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic components.

Q: Why is the TSOP2133 recommended over the RPM6933?

A: The TSOP2133 is actively manufactured and available, whereas the RPM6933 is obsolete. The TSOP2133 provides superior performance characteristics including extended sensing distance and defined operating temperature range, while maintaining full electrical and mechanical compatibility.
