RPM7137-R Equivalent & Substitute Parts

Part Overview

The RPM7137-R is a remote receiver sensor manufactured by Rohm Semiconductor, designed for infrared signal reception at 36.7kHz with a 15-meter sensing distance. This component is classified as obsolete, making equivalent and substitute parts necessary for ongoing system maintenance and new design implementations. The part operates within a 4.5V to 5.5V supply range with 1.5mA current consumption and is housed in a through-hole mounting configuration suitable for standard PCB assembly.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RPM7137-R is determined by the following critical parameters:

• B.P.F. Center Frequency: Must match 36.7kHz for signal compatibility with existing infrared transmission systems
• Mounting Type: Must be through-hole to maintain PCB assembly compatibility
• Orientation: Must be side view to fit existing mechanical layouts
• Voltage Supply Range: Must accommodate the system's power supply specifications
• RoHS Compliance: Must meet ROHS3 requirements for regulatory compliance

The TSOP32137 from Vishay Semiconductor Opto Division satisfies all critical substitution criteria, sharing the same 36.7kHz center frequency, through-hole mounting configuration, side-view orientation, and ROHS3 compliance status.

Parameter Comparison

Engineering Selection Recommendations

The TSOP32137 is a direct functional substitute for the RPM7137-R based on matching critical electrical and mechanical parameters. Both components operate at the same 36.7kHz center frequency and share identical through-hole, side-view mounting configurations. The TSOP32137 maintains ROHS3 compliance and is currently in active production status, ensuring long-term availability and supply chain stability.

The TSOP32137 demonstrates superior performance characteristics in several areas: extended sensing distance (35m versus 15m), lower supply current consumption (350µA versus 1.5mA), wider voltage supply range (2.7V to 5.5V versus 4.5V to 5.5V), and broader operating temperature range (-25°C to 85°C versus -10°C to 75°C). The improved moisture sensitivity level (MSL 1 versus MSL 3) provides enhanced reliability in humid environments.

Frequently Asked Questions (FAQ)

Q: Can the TSOP32137 directly replace the RPM7137-R in existing designs?

A: Yes. Both components share the same 36.7kHz center frequency, through-hole mounting type, and side-view orientation. The TSOP32137 is electrically and mechanically compatible with applications designed for the RPM7137-R.

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

A: The TSOP32137 offers extended sensing distance (35m versus 15m), significantly lower current consumption (350µA versus 1.5mA), a wider voltage supply range (2.7V to 5.5V versus 4.5V to 5.5V), and a broader operating temperature range (-25°C to 85°C versus -10°C to 75°C). The TSOP32137 also features superior moisture sensitivity characteristics.

Q: Why is the RPM7137-R listed as obsolete?

A: The RPM7137-R is no longer in active production. The TSOP32137 represents the current-generation equivalent from an active manufacturer, providing improved specifications and guaranteed long-term availability.

Q: Are both components RoHS compliant?

A: Yes. Both the RPM7137-R and TSOP32137 meet ROHS3 compliance requirements.

Q: What is the impact of the different moisture sensitivity levels?

A: The RPM7137-R has MSL 3 (168-hour shelf life limit), while the TSOP32137 has MSL 1 (unlimited shelf life). The TSOP32137 provides superior protection against moisture absorption during storage and handling.
