Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ELFH0921G is determined by the following critical parameters:

• Pitch specification: 0.200" (5.08mm) — the fundamental spacing requirement for connector compatibility
• Header orientation: Right-angle (90°) configuration for PCB mounting alignment
• Termination method: Solder termination for permanent circuit board attachment
• Mounting type: Through-hole technology for mechanical and electrical stability
• Regulatory compliance: RoHS compliance and MSL rating for manufacturing process compatibility
• HTSUS classification: 8536.69.4040 — confirms product category alignment

The substitute part 796638-9 (TE Connectivity AMP Connectors) meets these core substitution criteria through matching pitch, orientation, termination style, and mounting methodology. Both parts are active products with RoHS compliance and identical MSL ratings, establishing functional equivalence within the terminal block category.

Parameter Comparison

Engineering Selection Recommendations

Both the ELFH0921G and 796638-9 are active products with current manufacturing status and full RoHS compliance certification. Selection between these parts should be based on:

• Inventory availability: ELFH0921G has 794 units in stock; 796638-9 has 1284 units in stock
• Supply chain requirements: Both parts carry identical ECCN and HTSUS classifications, ensuring equivalent regulatory treatment
• Compliance status: Both parts meet MSL Level 1 requirements, suitable for standard manufacturing processes without special moisture control
• Manufacturer qualification: Component selection should align with existing design documentation and manufacturer approval lists

No additional testing or verification is required when substituting between these parts, provided the pitch, orientation, and termination specifications match the original design requirements.

Frequently Asked Questions (FAQ)

Q: What makes 796638-9 a valid substitute for ELFH0921G?

A: Both parts share the critical substitution parameters: 0.200" (5.08mm) pitch, right-angle orientation, solder termination, through-hole mounting, active product status, RoHS compliance, and identical MSL and ECCN classifications. These parameters establish functional equivalence within the terminal block category.

Q: Are there any differences in electrical performance between these parts?

A: The substitute part 796638-9 specifies electrical ratings of 15 A (UL) and 300 V (UL). The ELFH0921G does not provide electrical ratings in the available documentation. Design validation should confirm that the substitute part's ratings meet or exceed the application requirements.

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

A: Yes, provided the PCB layout accommodates the 0.200" (5.08mm) pitch spacing and right-angle mounting configuration. Both parts use through-hole termination and are designed for standard solder attachment processes.

Q: What is the significance of the MSL Level 1 rating?

A: MSL Level 1 indicates unlimited shelf life without moisture control requirements. Both parts can be stored and handled using standard manufacturing practices without special desiccant packaging or baking procedures.

Q: How do the base product numbers relate to these parts?

A: ELFH0921G is based on the ELFH092 platform; 796638-9 is based on the 796638 platform. The base numbers identify the product family, while the suffix designates specific configurations within that family.
