Equivalent & Substitute Parts for RBL-1205S/EH

Part Overview

The Recom Power RBL-1205S/EH is an isolated DC-DC converter module featuring a single 5V output at up to 50mA (250 mW), with a 10.8V–13.2V input voltage range, 2kV isolation, through-hole mounting, and a 6-SIP package. The product is classified as obsolete, making it necessary to identify alternative models for maintenance, production continuity, and component sourcing.

Key Parameters

Substitute Part Grouping Explanation

Substitution is determined by direct comparison of the following parameters: input voltage range, output voltage, output current rating (minimum output current and power must meet or exceed original), isolation voltage, mounting type, package style, operating temperature, compliance status (RoHS, REACH), and application category. Only parts matching or exceeding all these criteria are considered functional substitutes.

Key parameters for grouping include:

• Voltage - Input (Min/Max)
• Voltage - Output 1
• Current - Output (Max)
• Power (Watts)
• Voltage - Isolation
• Mounting Type
• Package / Case
• RoHS Status
• MSL
• REACH Status

Parameter Comparison

Engineering Selection Recommendations

The RBL-1205S/EH is obsolete. The RB-1205S/H, with active status, shares the critical input and output voltages, current rating (equal or higher), isolation voltage, efficiency, and regulatory compliance (RoHS3, REACH). Differences in operating temperature, package type (6-SIP vs. 7-SIP), and output capacity are noted, but all key matching parameters are fully met per supplied data.

Frequently Asked Questions (FAQ)

Q1: What criteria are used to determine acceptable substitute DC-DC converters?
A1: Substitution is permitted when the following critical parameters match: input voltage range, output voltage, output current or power equal to or greater than required, isolation voltage, mounting type, package compatibility, operating temperature, and compliance (RoHS, REACH).

Q2: Is it acceptable to use substitute parts with a different SIP pin count?
A2: Only parameters explicitly provided are evaluated. Both main and substitute offer through-hole mounting and 5 leads, but note the package type difference (6-SIP vs. 7-SIP Module). Compatibility must comply with the specified mechanical format and lead arrangement.

Q3: What are the compliance statuses of the suggested substitute?
A3: Both RBL-1205S/EH and RB-1205S/H are ROHS3 compliant and REACH unaffected, with identical MSL ratings.

Q4: Does the substitute part support the same application category?
A4: The substitute matches the ITE (Commercial) application category and adds Medical applications per provided data.

Q5: Are there thermal or power derating considerations when selecting a substitute?
A5: Only the supplied operating temperature range and maximum power rating are considered in substitution. The substitute part supports an operating temperature to 85°C and a maximum power rating of 1 W.
