Substitute Part Grouping Explanation

The substitute part 796638-3 (TE Connectivity AMP Connectors) is identified as functionally equivalent based on the following shared parameters:

Substitution Criteria:

• Pitch specification: 0.200" (5.08mm) — matches the standardized spacing requirement
• Header orientation: 90° right-angle configuration — ensures compatible PCB mounting geometry
• Category classification: Terminal Blocks — same functional component class
• Packaging format: Bulk — consistent supply format
• Compliance standards: Both parts are RoHS compliant and carry EAR99 ECCN classification
• Moisture sensitivity: Both rated MSL 1 (Unlimited) — equivalent environmental handling
• HTSUS code alignment: 8536.69.4040 — same tariff classification

The 796638-3 provides a 3-position configuration with active product status and established inventory availability, making it a viable alternative when ELFH0321G stock is unavailable.

Parameter Comparison

Engineering Selection Recommendations

Both ELFH0321G and 796638-3 maintain active product status with established manufacturer support and supply chains. Selection between these parts should be based on:

Compliance Alignment: The ELFH0321G is RoHS Compliant, while the 796638-3 is ROHS3 Compliant. Both satisfy RoHS requirements; ROHS3 represents the current regulatory standard. Both parts carry EAR99 ECCN classification and share identical HTSUS tariff codes, indicating equivalent trade and export compliance profiles.

Inventory and Availability: ELFH0321G has 710 pieces in new original stock. The 796638-3 has 7230 pieces available, providing significantly higher inventory depth for applications requiring volume procurement.

Moisture Sensitivity: Both components are rated MSL 1 (Unlimited), indicating no moisture sensitivity constraints during storage or handling.

Electrical and Mechanical Specifications: The 796638-3 provides documented electrical ratings (15 A UL, 300 V UL) and thermal operating range (-40°C ~ 110°C), along with material certifications (UL94 V-0). These specifications are not provided for the ELFH0321G in the available data.

Frequently Asked Questions (FAQ)

Q: What makes 796638-3 a suitable substitute for ELFH0321G?

A: Both components share the critical substitution parameters: 0.200" (5.08mm) pitch spacing, 90° right-angle header orientation, terminal block category classification, bulk packaging format, and equivalent compliance certifications (RoHS, EAR99, MSL 1). These parameters define functional compatibility in PCB-mounted terminal block applications.

Q: Are there differences in position count between these parts?

A: The ELFH0321G position count is not specified in the available data. The 796638-3 is a 3-position configuration with 3 positions per level and 1 level. Position count must be verified against your specific circuit requirements before substitution.

Q: What is the difference between RoHS Compliant and ROHS3 Compliant?

A: Both designations indicate compliance with RoHS (Restriction of Hazardous Substances) regulations. ROHS3 represents the current regulatory iteration. Both parts meet RoHS requirements; ROHS3 is the more recent standard designation.

Q: Can I use 796638-3 if my application requires specific electrical ratings?

A: The 796638-3 carries UL ratings of 15 A at 300 V with an operating temperature range of -40°C ~ 110°C. Verify these ratings against your application requirements. The ELFH0321G electrical specifications are not provided in the available data; contact the manufacturer for complete specifications if needed.

Q: What is the significance of the MSL 1 (Unlimited) rating?

A: MSL 1 (Unlimited) indicates that the component has no moisture sensitivity constraints. Both parts can be stored and handled without special moisture control measures, simplifying supply chain management.

Q: Are there any material or construction differences I should consider?

A: The 796638-3 specifies Copper Alloy contacts with Polyamide (PA66) Nylon 6/6 housing, tin contact mating finish, and UL94 V-0 flammability rating. These specifications are not provided for the ELFH0321G. Material specifications should be confirmed with the manufacturer if your application has specific material requirements.
