RPM7136-H4R Equivalent & Substitute Parts

Part Overview

The RPM7136-H4R is a remote receiver sensor manufactured by Rohm Semiconductor, designed for 36.0kHz infrared signal reception with a 15-meter sensing distance. This through-hole optical sensor operates within a 4.5V to 5.5V supply range and draws 1.5mA during operation. The product is classified as obsolete, making equivalent substitute parts necessary for new designs and ongoing production requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RPM7136-H4R are qualified based on the following critical parameters:

• B.P.F. Center Frequency: Must match 36.0kHz for infrared signal compatibility
• Mounting Type: Must be Through Hole to maintain PCB integration compatibility
• RoHS Compliance: Must maintain ROHS3 Compliant status for regulatory alignment
• Voltage Supply Range: Substitute must accommodate the original operating voltage or provide a compatible superset range
• Current Supply: Substitute specifications must be compatible with existing circuit design parameters

The substitute parts TSOP34136 and TSOP34336 meet these criteria. Both are manufactured by Vishay Semiconductor Opto Division, operate at 36.0kHz, use through-hole mounting, and maintain ROHS3 compliance.

Parameter Comparison

Engineering Selection Recommendations

Both TSOP34136 and TSOP34336 are active products from Vishay Semiconductor Opto Division and serve as direct functional equivalents to the obsolete RPM7136-H4R. Selection between these two substitutes depends on packaging requirements:

• TSOP34336 is supplied in bulk packaging, matching the original RPM7136-H4R packaging format
• TSOP34136 is supplied in tube packaging, suitable for automated assembly processes

Both substitutes provide extended operating temperature ranges (-25°C to 85°C versus -10°C to 75°C) and improved power efficiency (350µA versus 1.5mA supply current). The voltage supply range of 2.5V to 5.5V encompasses the original 4.5V to 5.5V specification. Both maintain ROHS3 compliance and are currently in active production status.

Frequently Asked Questions (FAQ)

Q: Can TSOP34136 and TSOP34336 be used interchangeably with RPM7136-H4R?

A: Yes. Both substitutes operate at the same 36.0kHz center frequency, use through-hole mounting, and maintain identical RoHS compliance. The primary difference is packaging format: TSOP34336 uses bulk packaging while TSOP34136 uses tube packaging.

Q: What is the impact of the increased sensing distance in substitute parts?

A: TSOP34136 and TSOP34336 provide 45-meter sensing distance compared to the RPM7136-H4R's 15-meter range. This extended range does not negatively affect applications designed for shorter distances and provides additional capability for designs requiring extended reception range.

Q: Are there voltage supply compatibility concerns?

A: No. The substitute parts operate across 2.5V to 5.5V, which fully encompasses the original 4.5V to 5.5V specification. Existing circuit designs operating at 4.5V to 5.5V will function without modification.

Q: What is the significance of the reduced current consumption in substitute parts?

A: TSOP34136 and TSOP34336 consume 350µA compared to RPM7136-H4R's 1.5mA. This represents improved power efficiency and reduced thermal load, beneficial for battery-powered and thermally constrained applications.

Q: Does the extended operating temperature range affect compatibility?

A: No. The substitute parts operate across -25°C to 85°C, which exceeds the original -10°C to 75°C range. Existing designs will continue to function within their original temperature specifications.

Q: Which substitute should be selected for new production?

A: TSOP34336 is recommended for new production due to bulk packaging compatibility with the original RPM7136-H4R format. TSOP34136 is suitable for automated assembly environments requiring tube packaging.
