RPM7140-R Remote Receiver Sensor Equivalent & Substitute Parts

Part Overview

The RPM7140-R is a remote receiver sensor manufactured by Rohm Semiconductor, designed for infrared remote control applications operating at 40.0kHz with a 15-meter sensing distance. This component is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system support and new design implementations. The sensor features through-hole mounting and operates within a 4.5V to 5.5V supply range, drawing 1.5mA during operation.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RPM7140-R is determined by the following critical parameters:

• B.P.F. Center Frequency: Must match 40.0kHz for signal compatibility with existing infrared remote control protocols
• Mounting Type: Must be through-hole to ensure mechanical compatibility with PCB layouts
• Orientation: Must be side view to maintain form factor consistency
• RoHS Compliance: Must meet ROHS3 requirements for regulatory alignment
• Supply Voltage Range: Must accommodate the system's power supply specifications
• Operating Temperature Range: Must support the intended application environment

The TSOP58440 from Vishay Semiconductor Opto Division meets all critical substitution criteria, sharing the same 40.0kHz center frequency, through-hole mounting, side-view orientation, and ROHS3 compliance status.

Parameter Comparison

Engineering Selection Recommendations

The TSOP58440 is a direct functional substitute for the RPM7140-R based on the following engineering criteria:

Frequency Alignment: Both sensors operate at 40.0kHz, ensuring compatibility with existing infrared remote control signal protocols without circuit modification.

Mechanical Compatibility: Identical through-hole mounting and side-view orientation allow direct PCB layout compatibility without redesign.

Regulatory Compliance: Both components maintain ROHS3 compliance and REACH unaffected status, satisfying current environmental and regulatory requirements.

Electrical Performance: The TSOP58440 operates within an expanded voltage range (2.5V ~ 5.5V) that fully encompasses the RPM7140-R specification (4.5V ~ 5.5V), with reduced supply current consumption (700µA versus 1.5mA).

Extended Operating Range: The TSOP58440 provides superior sensing distance (40m versus 15m) and broader operating temperature range (-25°C ~ 85°C versus -10°C ~ 75°C), offering enhanced performance margins for demanding applications.

Production Status: The TSOP58440 is currently in active production with documented inventory availability, eliminating obsolescence risk associated with the RPM7140-R.

Frequently Asked Questions (FAQ)

Q: Can the TSOP58440 directly replace the RPM7140-R without circuit modifications?

A: Yes. Both sensors share identical 40.0kHz center frequency, through-hole mounting, and side-view orientation. The TSOP58440's expanded voltage range (2.5V ~ 5.5V) fully accommodates the RPM7140-R's 4.5V ~ 5.5V requirement, requiring no circuit changes.

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

A: The TSOP58440 provides extended sensing distance (40m versus 15m), lower supply current (700µA versus 1.5mA), broader operating temperature range (-25°C ~ 85°C versus -10°C ~ 75°C), and active production status versus obsolete status.

Q: Are there any compatibility concerns with the increased sensing distance of the TSOP58440?

A: No. Extended sensing distance represents enhanced capability without introducing incompatibility. The 40.0kHz frequency matching ensures protocol compatibility regardless of range differences.

Q: Do both sensors meet current regulatory requirements?

A: Yes. Both the RPM7140-R and TSOP58440 are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards.

Q: What is the packaging difference between these parts?

A: The RPM7140-R is supplied in standard packaging, while the TSOP58440 is supplied in bulk packaging. Both maintain identical electrical and mechanical specifications for the sensor element itself.

Q: Is the TSOP58440 available in current inventory?

A: Yes. The TSOP58440 is an active product with documented new original stock availability, providing supply chain continuity for the obsolete RPM7140-R.
