Key Parameters

Substitute Part Grouping Explanation

Substitute candidate identification is strictly determined by matching the following key parameters:

• Input voltage range (18V to 36V)
• Output voltages (+15V, -15V)
• Output currents (250mA each output)
• Total output power (7.5 W)
• Isolation voltage (1.5 kV)
• Module type (Isolated Module with two outputs)
• Mounting type (Through Hole)
• ROHS3 compliance
• Application category (ITE Commercial)

Mechanical suitability is based on package type dimensions and mounting method. Only substitutes meeting these explicit criteria are included.

Parameter Comparison

Engineering Selection Recommendations

EC3B15 is obsolete; engineering selection for ongoing production or maintenance applications requires an active part with matching electrical, mechanical, and regulatory parameters. EC6A16 offers the same input range, output voltages, output currents, power, isolation, features, and regulatory compliance (ROHS3, REACH, ECCN, HTSUS). EC6A16 is active and conforms to required certifications, supporting seamless transitions within the ITE Commercial category.

Frequently Asked Questions (FAQ)

Q1: What determines a compatible substitute for EC3B15?
A substitute must match input voltage range, output voltages, output current, total power, isolation voltage, module type, mounting type, and regulatory compliance.

Q2: Is package size and pinout identical between EC3B15 and EC6A16?
Package and dimensions differ. EC3B15 uses a 5-DIP Module, 2.00" x 1.00" x 0.40". EC6A16 utilizes 24-DIP Module, 1.25" x 0.80" x 0.40". Mechanical adaptation may be required.

Q3: Does EC6A16 maintain the same safety and compliance standards?
EC6A16 is ROHS3 compliant, REACH unaffected, and has matching ECCN and HTSUS codes as EC3B15.

Q4: How does the operating temperature of EC6A16 compare to EC3B15?
EC6A16 supports a broader operating temperature (-40°C ~ 100°C with derating) versus EC3B15 (-25°C ~ 71°C).

Q5: Are both parts suited for ITE (Commercial) applications?
Both EC3B15 and EC6A16 are specified for use in ITE (Commercial) applications.

Q6: Does substitution affect output performance?
No changes occur in output voltages, output currents, power rating, or isolation when substituting EC3B15 with EC6A16 per provided criteria.
