Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ELFH1621G is determined by the following critical parameters:

• Pitch specification: 0.200" (5.08mm) center-to-center spacing
• Form factor: Right-angle (90°) header orientation
• Connector type: Terminal block header with male pins
• Mounting method: Through-hole PCB mounting
• Packaging format: Bulk supply
• Regulatory compliance: RoHS compliance status and ECCN classification

The identified substitute part 1-796638-6 (TE Connectivity AMP Connectors) meets these core substitution criteria. Both components share identical pitch spacing, right-angle orientation, through-hole mounting architecture, and equivalent regulatory compliance profiles. The substitute maintains functional and mechanical compatibility within the terminal block header category.

Parameter Comparison

Engineering Selection Recommendations

Both the ELFH1621G and 1-796638-6 maintain active product status with established supply chains. The TE Connectivity substitute (1-796638-6) provides additional documented electrical specifications including 15 A current rating (UL), 300 V voltage rating (UL), and operating temperature range of -40°C to 110°C. Both components are RoHS compliant and carry unlimited moisture sensitivity ratings, indicating suitability for standard industrial storage and handling conditions. Selection between these parts may be based on availability, established supplier relationships, or specific application requirements where the documented electrical parameters of the substitute are beneficial.

Frequently Asked Questions (FAQ)

Q: What makes 1-796638-6 a valid substitute for ELFH1621G?

A: Both components share the critical substitution parameters: 0.200" (5.08mm) pitch spacing, right-angle header orientation, through-hole mounting, bulk packaging, active product status, and equivalent RoHS/ECCN compliance. These parameters define functional and mechanical compatibility within the terminal block header category.

Q: Are there differences in electrical ratings between these parts?

A: The TE Connectivity substitute (1-796638-6) provides documented electrical specifications: 15 A (UL), 300 V (UL), and -40°C to 110°C operating temperature. The Amphenol ELFH1621G does not have these parameters specified in available documentation. Applications requiring verified electrical performance should reference the substitute's datasheet.

Q: Can these parts be used interchangeably on the same PCB?

A: Yes. Both components feature identical 0.200" (5.08mm) pitch spacing and right-angle through-hole mounting, ensuring mechanical and electrical compatibility on PCBs designed for this connector family.

Q: What is the significance of the base product number ELFH162?

A: The base product number ELFH162 identifies the core product family. The ELFH1621G represents a specific variant within this family. Substitute parts may reference different base numbers (such as 796638 for the TE Connectivity part) while maintaining functional equivalence.

Q: Are both parts suitable for industrial applications?

A: Yes. Both components carry active product status, RoHS compliance, and unlimited MSL ratings, indicating suitability for standard industrial control, telecommunications, and modular assembly applications.
