RTS-153.3 Equivalent & Substitute Parts Reference

Part Overview

The Recom Power RTS-153.3 is an isolated module DC-DC converter delivering 3.3V at up to 606mA from a 13.5V to 16.5V input, with 2W power output. This model is part of the ECONOLINE RTS (2W) series, features SCP, and is designed for ITE (Commercial) applications. The device utilizes a surface mount 8-SMD Module, 5 Leads package. Product status is "Obsolete," creating a critical need for suitable alternative models that conform strictly to the defined electrical and mechanical parameters to ensure both functional and regulatory compatibility in replacement scenarios.

Substitute Part Grouping Explanation

Substitution is guided by matching all critical functional, electrical, mechanical, and compliance parameters explicitly listed. Only parts meeting the following criteria are grouped as substitutes:

• Isolated module, 1 output, identical input/output voltage, current, and power ratings
• Surface mount 8-SMD Module, 5 Leads package with similar dimensions
• Identical application (ITE Commercial), SCP feature, and efficiency
• Meeting required compliance: ROHS3, REACH, ECCN, HTSUS, MSL
• Consistent voltage isolation rating
• Compatible operating temperature range

Parameter Comparison

Engineering Selection Recommendations

Substitution is justified on the basis of RTS-153.3 being obsolete. The R2S-153.3 conforms to all listed electrical, mechanical, and compliance criteria, and is active in production. Both are ROHS3 Compliant, REACH Unaffected, and share identical ECCN and HTSUS codes. Moisture Sensitivity Level is maintained at 1 (Unlimited). Package format and mounting type remain consistent, with minor dimensional variation noted. Use of the substitute is aligned directly with compliance and certification parameters specified.

Frequently Asked Questions (FAQ)

Q1: What are the critical factors for substituting RTS-153.3 with R2S-153.3?
A1: Critical factors include matching isolated module type, single output channel, input/output voltage and current specifications, power rating, package format, dimensions, compliance certifications, and application suitability.

Q2: Are there any differences in package or mounting between RTS-153.3 and R2S-153.3?
A2: Both utilize a surface mount 8-SMD Module, 5 Leads format. R2S-153.3 has a slightly wider dimension (10.7mm vs. 9.3mm), but length and height are identical.

Q3: Is there any change in compliance certifications between the main part and substitute?
A3: No. Both RTS-153.3 and R2S-153.3 are ROHS3 Compliant, REACH Unaffected, with ECCN EAR99 and HTSUS 8504.40.9580.

Q4: Does operating temperature range differ for the substitute?
A4: Yes. R2S-153.3 offers an extended operating range of -40°C to 100°C compared to RTS-153.3’s -40°C to 85°C.

Q5: Is the substitute suitable for the same application?
A5: Yes. Both parts are designed for ITE (Commercial) applications and include SCP feature.

Q6: What considerations should be made for physical layout in substitution?
A6: Review the change in width dimension of the substitute in existing board layouts to ensure proper fit within the mechanical envelope.
