Substitute Part Grouping Explanation

The identified substitute part 796636-4 (TE Connectivity AMP Connectors) qualifies as an equivalent based on the following critical parameters:

Substitution Criteria:

• Pitch specification: 0.200" (5.08mm) — matches the primary dimensional requirement
• Orientation: Vertical header configuration — maintains the same mounting plane and connector approach
• Mounting type: Through hole — compatible with the same PCB assembly process
• Category classification: Terminal block header — functionally equivalent component class
• Regulatory compliance: RoHS compliant and EAR99 classification — meets the same compliance framework
• Moisture sensitivity: MSL 1 (Unlimited) — identical environmental handling requirements

The 796636-4 provides additional specified parameters including 4-position configuration, solder termination, tin contact mating finish, and operating temperature range of -40°C to 110°C, which establish it as a direct functional alternative for applications requiring vertical 5.08mm pitch terminal block headers.

Parameter Comparison

Engineering Selection Recommendations

Component selection between ELFH0425G and 796636-4 should be based on the following engineering factors:

Product Status and Compliance: Both parts maintain active product status and RoHS compliance, ensuring continued manufacturer support and regulatory alignment for new designs and production runs.

Regulatory and Trade Classification: Both components share identical ECCN (EAR99) and HTSUS (8536.69.4040) classifications, confirming equivalent export control and tariff treatment.

Environmental Handling: Both parts specify MSL 1 (Unlimited) moisture sensitivity, indicating no special storage or handling requirements and full compatibility with standard manufacturing environments.

Availability Considerations: The 796636-4 demonstrates significantly higher inventory availability (15651 pieces versus 846 pieces), which may influence lead time and supply chain continuity for high-volume production requirements.

Dimensional and Functional Compatibility: The 0.200" (5.08mm) pitch and vertical orientation are common to both parts, establishing mechanical and electrical compatibility for applications designed around this standard terminal block configuration.

Frequently Asked Questions (FAQ)

Q: What determines if 796636-4 can substitute for ELFH0425G?

A: Substitution is valid when the pitch (0.200"/5.08mm), header orientation (vertical), mounting type (through hole), and regulatory compliance (RoHS, EAR99) are identical. Both parts meet these criteria.

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

A: The 796636-4 specifies 15A current rating at 300V (UL standard), while the ELFH0425G does not provide electrical ratings in the available data. Applications requiring specific current or voltage ratings should reference the complete datasheets for both components.

Q: What is the significance of the pitch specification?

A: The 0.200" (5.08mm) pitch is the center-to-center distance between terminal positions. This dimension is critical for PCB layout compatibility. Both parts share this specification, ensuring mechanical fit in designs created for either component.

Q: How do packaging and inventory levels affect component selection?

A: Both parts are supplied in bulk packaging. The 796636-4 offers substantially higher inventory availability, which may reduce procurement lead times and support larger production volumes without supply constraints.

Q: What does MSL 1 (Unlimited) mean for handling and storage?

A: MSL 1 indicates the component has unlimited shelf life and requires no special moisture control during storage or handling. Standard warehouse conditions are sufficient for both parts.

Q: Are there any compatibility concerns with PCB assembly processes?

A: Both components use through-hole mounting and solder termination, making them compatible with standard PCB assembly equipment and processes. No special handling or equipment modifications are required.
