RPR-220C1N Equivalent & Substitute Parts

Part Overview

The RPR-220C1N is a reflective optical sensor manufactured by Rohm Semiconductor, designed for applications requiring photointerrupter functionality with a 0.236" (6mm) sensing distance. This component is classified as obsolete, which necessitates identification of equivalent substitute parts for ongoing design support and procurement continuity. The RPR-220C1N operates as a phototransistor-based reflective sensor suitable for through-hole mounting applications across industrial and consumer electronics.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RPR-220C1N are identified based on strict electrical and mechanical parameter alignment. The primary substitution criteria are:

• Sensing distance: 0.236" (6mm)
• Sensing method: Reflective
• Output type: Phototransistor
• Voltage rating: 30 V maximum collector-emitter breakdown
• Current rating: 30 mA maximum collector current and 30 mA maximum DC forward current
• Response time: 10µs
• Operating temperature range: -25°C ~ 85°C
• Mounting type: Through Hole
• Compliance: ROHS3 Compliant, REACH Unaffected

The RPR-220 meets all these criteria and serves as a direct functional equivalent, with the primary difference being packaging configuration (Radial - 4 Leads versus Module) and product status (Active versus Obsolete).

Parameter Comparison

Engineering Selection Recommendations

The RPR-220 is the appropriate substitute for the obsolete RPR-220C1N. Both components are manufactured by Rohm Semiconductor and share identical electrical specifications, sensing characteristics, and environmental operating parameters. The RPR-220 maintains active product status, ensuring long-term availability and supply chain continuity.

Both parts satisfy ROHS3 compliance and REACH regulatory requirements, making them suitable for applications subject to environmental and hazardous substance restrictions. The primary design consideration is the packaging difference: the RPR-220C1N uses a Module package configuration, while the RPR-220 uses a Radial - 4 Leads configuration. PCB layout and mechanical mounting must be evaluated to accommodate this packaging change.

Frequently Asked Questions (FAQ)

Q: Can the RPR-220 directly replace the RPR-220C1N in existing designs?

A: The RPR-220 provides electrical and functional equivalence to the RPR-220C1N. However, the packaging difference (Module versus Radial - 4 Leads) requires PCB layout modification and mechanical mounting adjustment. Electrical performance and sensing characteristics are identical.

Q: What is the primary reason for substitution?

A: The RPR-220C1N is classified as obsolete. The RPR-220 is an active product from the same manufacturer with identical electrical specifications, ensuring continued component availability and supply reliability.

Q: Are there compliance differences between the two parts?

A: No. Both the RPR-220C1N and RPR-220 are ROHS3 compliant and REACH unaffected, meeting the same regulatory requirements.

Q: What are the key electrical parameters that must match for substitution?

A: The critical parameters are sensing distance (0.236" / 6mm), sensing method (reflective), output type (phototransistor), voltage rating (30 V maximum), current ratings (30 mA maximum for both collector and forward current), response time (10µs), and operating temperature range (-25°C ~ 85°C).

Q: Does the packaging change affect the sensing performance?

A: No. The sensing distance, sensing method, response time, and all optical characteristics remain identical. The packaging change is mechanical only and does not affect sensor performance.
