Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the EC3AB14M is determined by strict parametric matching across electrical and mechanical specifications. The critical parameters that define substitutability are:

Electrical Parameters:

• Input voltage range: 9V to 18V
• Output voltage configuration: +5V and -5V dual output
• Output current capacity: 300mA per rail
• Power rating: 3W
• Isolation voltage: 500V
• Efficiency: 76%

Mechanical Parameters:

• Mounting type: Through Hole
• Package configuration: 24-DIP Module, 14 Leads
• Physical dimensions: 1.25" L x 0.80" W x 0.50" H

Compliance Parameters:

• RoHS3 Compliance
• REACH Unaffected status
• MSL Level 1

Parts qualify as substitutes only when all parameters match exactly across these three categories. Partial matches or parameter variations do not establish substitution relationships.

Parameter Comparison

Engineering Selection Recommendations

Both the EC3AB14M and EC3AB14 are active products manufactured by Cincon Electronics Co. LTD with identical electrical and mechanical specifications. Selection between these parts is based on availability and inventory status rather than technical differentiation.

EC3AB14M is recommended when:

• Higher inventory availability is required (1100 pieces in stock)
• Primary sourcing from the base model designation is preferred

EC3AB14 is recommended when:

• EC3AB14M availability is constrained
• Equivalent parametric performance is acceptable
• Inventory of 1086 pieces meets procurement requirements

Both parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment for commercial ITE applications. The identical operating temperature range (-25°C to 71°C), isolation voltage (500V), and efficiency rating (76%) confirm full functional interchangeability in circuit design applications.

Frequently Asked Questions (FAQ)

Q: Can EC3AB14 be used as a direct replacement for EC3AB14M?

A: Yes. The EC3AB14 is a parametric equivalent with identical electrical specifications, output configuration, isolation voltage, operating temperature range, efficiency, and mechanical package. Both parts are manufactured by Cincon Electronics Co. LTD and comply with ROHS3 and REACH requirements.

Q: What are the critical parameters that determine substitutability for this DC-DC converter?

A: Substitutability is determined by exact matching of: input voltage range (9V-18V), dual output voltage configuration (+5V/-5V), output current capacity (300mA per rail), power rating (3W), isolation voltage (500V), through-hole mounting type, 24-DIP Module 14-lead package, and physical dimensions (31.8mm x 20.3mm x 12.7mm).

Q: Are there any differences in compliance or regulatory status between EC3AB14M and EC3AB14?

A: No. Both parts carry identical compliance certifications: ROHS3 Compliant, REACH Unaffected status, and MSL Level 1 (Unlimited). No regulatory differentiation exists between the two part numbers.

Q: What is the significance of the 24-DIP Module, 14 Leads package specification?

A: The 24-DIP Module, 14 Leads package defines the physical form factor and pin configuration. This specification ensures mechanical and electrical compatibility with PCB layouts designed for either EC3AB14M or EC3AB14. Substitution requires identical package designation.

Q: How does the 500V isolation voltage specification affect substitution decisions?

A: The 500V isolation voltage is a critical electrical parameter that defines the maximum voltage differential between input and output circuits. Substitutes must maintain this exact isolation specification to preserve circuit safety and performance characteristics in isolated power supply applications.

Q: What inventory considerations should guide part selection between EC3AB14M and EC3AB14?

A: EC3AB14M has 1100 pieces in stock while EC3AB14 has 1086 pieces available. For applications requiring immediate availability or larger quantity procurement, EC3AB14M provides marginally higher inventory. Both quantities are sufficient for most commercial production requirements.

Q: Is the 76% efficiency rating a critical parameter for substitution?

A: Yes. The 76% efficiency rating is a specified electrical characteristic that affects thermal performance and power dissipation in the application circuit. Substitutes must maintain this efficiency specification to ensure equivalent thermal behavior and system-level power budget calculations.
