RZ-0505S/P Equivalent & Substitute Parts

Part Overview

The RZ-0505S/P is an isolated module DC-DC converter from Recom Power's ECONOLINE RZ series, designed for single 5V output applications with 100mA maximum current capacity. This component operates across a 4.75V to 5.25V input range and provides 1 kV isolation, making it suitable for ITE (Commercial) applications requiring galvanic isolation.

The RZ-0505S/P is classified as obsolete. Identifying equivalent substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production or maintenance requirements for systems utilizing this converter topology.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RZ-0505S/P is determined by strict alignment of the following critical parameters:

Electrical Specifications:

• Input voltage range: 4.75V to 5.25V
• Output voltage: 5V
• Maximum output current: 100mA
• Power rating: 500 mW
• Isolation voltage: 1 kV

Mechanical & Environmental Specifications:

• Mounting type: Surface Mount
• Package configuration: 10-SMD Module, 6 Leads
• Moisture sensitivity level: 1 (Unlimited)
• RoHS compliance: ROHS3 Compliant

Functional Requirements:

• Single isolated output
• Short-circuit protection (SCP) feature
• ITE (Commercial) application suitability

The R0.5Z-0505/P qualifies as a direct substitute based on matching all electrical specifications, isolation characteristics, mounting configuration, and regulatory compliance requirements. Dimensional variations and operating temperature range differences do not affect functional substitutability within the specified electrical parameters.

Engineering Selection Recommendations

The R0.5Z-0505/P is a qualified substitute for the obsolete RZ-0505S/P based on the following engineering criteria:

Electrical Equivalence: All critical electrical parameters are identical, including input voltage range (4.75V to 5.25V), output voltage (5V), maximum output current (100mA), power rating (500 mW), and isolation voltage (1 kV). The converter topology and short-circuit protection feature remain unchanged.

Mechanical Compatibility: Both parts utilize identical 10-SMD Module packaging with 6 leads and surface mount configuration, ensuring PCB layout and assembly process compatibility without design modification.

Regulatory Compliance: The R0.5Z-0505/P maintains ROHS3 compliance and MSL 1 (Unlimited) rating, meeting the same environmental and regulatory requirements as the original part.

Product Status Advantage: The R0.5Z-0505/P is classified as Active, providing assured long-term availability and supply chain continuity compared to the obsolete RZ-0505S/P.

Operating Temperature Consideration: The R0.5Z-0505/P extends the operating temperature range to -40°C to 100°C, providing enhanced thermal performance margin for applications operating at elevated temperatures within the specified input voltage window.

Frequently Asked Questions (FAQ)

Q: Can the R0.5Z-0505/P directly replace the RZ-0505S/P without circuit modification?

A: Yes. The R0.5Z-0505/P is electrically and mechanically equivalent. All input/output voltage specifications, current ratings, isolation voltage, and package configuration are identical. Direct substitution is supported without circuit redesign.

Q: What is the primary difference between these two parts?

A: The RZ-0505S/P is obsolete, while the R0.5Z-0505/P is an active product from the same manufacturer. The R0.5Z-0505/P also features an extended operating temperature range (-40°C to 100°C versus -40°C to 70°C), providing additional thermal margin.

Q: Are the physical dimensions identical?

A: The parts have minor dimensional variations. The RZ-0505S/P measures 0.60" L x 0.32" W x 0.29" H (15.2mm x 8.2mm x 7.3mm), while the R0.5Z-0505/P measures 0.60" L x 0.42" W x 0.28" H (15.2mm x 10.7mm x 7.0mm). Length and height are essentially equivalent; width differs by 0.5mm. PCB layout verification is recommended to confirm clearance in space-constrained applications.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both the RZ-0505S/P and R0.5Z-0505/P are ROHS3 compliant, REACH unaffected, and classified as MSL 1 (Unlimited). Regulatory compliance is equivalent.

Q: What is the packaging difference?

A: The RZ-0505S/P is supplied in standard packaging, while the R0.5Z-0505/P is supplied in Tube packaging. This affects logistics and handling but does not impact electrical or mechanical performance.

Q: Is the R0.5Z-0505/P suitable for applications requiring the full -40°C to 70°C range?

A: Yes. The R0.5Z-0505/P operating range of -40°C to 100°C fully encompasses the original -40°C to 70°C specification, ensuring compatibility with all temperature profiles supported by the RZ-0505S/P.
