Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ELF-16M130A is determined by the following critical parameters:

Primary Matching Criteria:

• Number of Lines: 2 (mandatory)
• Current Rating (Max): 1.3A (mandatory)
• Mounting Type: Through Hole (mandatory)
• Package / Case: Vertical, 4 PC Pin (mandatory)
• Physical Dimensions: Compatible footprint within specified height and length/width tolerances

Secondary Compatibility Factors:

• DC Resistance (DCR): Acceptable range determined by application requirements
• Mechanical fit: Pin configuration and board spacing compatibility

The substitute part B82731M2132A030 meets all primary matching criteria, maintaining identical current rating, line configuration, mounting type, and pin package structure. Physical dimensions remain compatible with the original design envelope.

Parameter Comparison

Engineering Selection Recommendations

B82731M2132A030 Suitability:

The B82731M2132A030 qualifies as a functional substitute based on matching electrical specifications (1.3A current rating, 2-line configuration) and compatible through-hole mounting architecture. The substitute maintains identical pin count and vertical package orientation, ensuring mechanical compatibility with existing PCB layouts.

Compliance Considerations:

The substitute part carries active product status with ROHS3 compliance and REACH affected designation, providing superior long-term availability and regulatory alignment compared to the obsolete ELF-16M130A. Certifications include ENEC, UR, and VDE approval agencies.

Parameter Variance:

The DC resistance differential (280mOhm typical for B82731M2132A030 versus 160mOhm for ELF-16M130A) represents a 120mOhm increase. Length dimension increases from 15.00mm to 21.00mm. These variations require validation against specific application thermal and spatial constraints.

Frequently Asked Questions (FAQ)

Q: Can B82731M2132A030 directly replace ELF-16M130A in existing designs?

A: Mechanical compatibility is confirmed through matching pin configuration, vertical orientation, and identical maximum height. Electrical compatibility requires verification that the 280mOhm DCR and increased length accommodate application requirements.

Q: What is the primary reason for substitution?

A: The ELF-16M130A is classified as obsolete. The B82731M2132A030 provides equivalent functionality with active product status and modern compliance certifications.

Q: Are there dimensional constraints for board layout?

A: The substitute part increases length from 15.00mm to 21.00mm. PCB layout must accommodate this 6.00mm increase in the longitudinal direction while maintaining the identical 20.50mm maximum height.

Q: How does the higher DC resistance affect performance?

A: The 120mOhm increase in DCR will result in proportionally higher resistive losses and heat generation at rated current. Application thermal analysis must confirm acceptability within system operating parameters.

Q: What compliance advantages does the substitute provide?

A: B82731M2132A030 is ROHS3 compliant and carries REACH affected status, ensuring regulatory alignment with current environmental standards. The original part is RoHS non-compliant.

Q: Are packaging formats compatible?

A: Both parts utilize vertical, 4 PC pin through-hole packages. The substitute is supplied in tray packaging versus the original specification, which does not affect functional compatibility.
