Equivalent & Substitute Parts Reference: VIBLSD1-S12-S5-DIP

Part Overview

Manufacturer Part Number VIBLSD1-S12-S5-DIP is an isolated DC DC converter module with 1 output, providing 5V at up to 150mA from an input voltage range of 11.4V to 12.6V. It features a 1W power output, 1kV isolation, SCP (short-circuit protection), and a 14-DIP through-hole package. This product is listed as Obsolete, which creates the need to identify equivalent substitute parts for ongoing designs, repairs, or inventory management.

Key Parameters

Substitute Part Grouping Explanation

Substitution is based strictly on matching or exceeding parameters that control electrical performance and safety in isolated DC DC converter modules. The core substitution parameters used are:

• Number of Outputs
• Input Voltage Range
• Output Voltage and Current
• Output Power (Watts)
• Isolation Voltage
• Package Type (Mounting, DIP)
• Operating Temperature Range
• Regulatory Compliance (RoHS, REACH)
• Application Suitability (ITE Commercial)

Only parts explicitly listed by the manufacturer or within the same electrical/mechanical constraints are considered substitutes.

Parameter Comparison

Engineering Selection Recommendations

The main part VIBLSD1-S12-S5-DIP is obsolete, which restricts ongoing direct procurement. PYSE1-S12-S5-D is recommended as a substitute based on manufacturer recommendation, active product status, and identical RoHS3 and REACH compliance. Both parts are compliant with regulatory and certification standards. Only substitute parts listed with matching compliance, ECCN, HTSUS, and compatible electrical parameters are suitable for selection.

Frequently Asked Questions (FAQ)

Q1: What parameters determine if PYSE1-S12-S5-D is a valid substitute for VIBLSD1-S12-S5-DIP?
A1: Substitution is valid based on matching output voltage (5V), output power rating (1W), isolated module type, mounting method (through hole), and compliance certifications. Input voltage range and output current capability must encompass requirements.

Q2: Is the package footprint the same between VIBLSD1-S12-S5-DIP and PYSE1-S12-S5-D?
A2: The original part uses a 14-DIP module (300 mil, 5 leads), whereas the substitute uses 8-DIP module, 4 leads. Package compatibility should be checked against mechanical constraints.

Q3: How do the electrical isolation ratings compare?
A3: VIBLSD1-S12-S5-DIP provides 1 kV isolation; PYSE1-S12-S5-D provides 1.5 kV isolation.

Q4: Is there any difference in environmental compliance or certifications?
A4: Both parts are ROHS3 Compliant, REACH Unaffected, ECCN EAR99, and HTSUS 8504.40.9580.

Q5: Will the substitute part’s operating temperature range affect use in existing applications?
A5: The substitute has a wider operating temperature range (-40°C ~ 105°C with derating) compared to -40°C ~ 85°C. This provides expanded design flexibility within rated conditions.
