ELFH0621G Equivalent & Substitute Parts

Part Overview

The ELFH0621G is a .200"/5.08MM right-angle header terminal block manufactured by Amphenol PCD. This component is classified as a position terminal block and is currently in active product status with 973 pieces available in new original inventory. Terminal blocks of this specification are essential in applications requiring reliable electrical connections with standardized pitch spacing and right-angle orientation for PCB mounting. Substitute parts are identified to provide alternative sourcing options when the primary part is unavailable or when design flexibility permits component selection from qualified manufacturers.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ELFH0621G is determined by the following critical parameters:

• Pitch Specification: 0.200" (5.08mm) — the fundamental spacing standard that ensures mechanical and electrical compatibility
• Header Orientation: Right-angle (90°) configuration for PCB mounting alignment
• Connector Type: Terminal block header with male pins
• Packaging Format: Bulk packaging for component-level integration
• Regulatory Compliance: RoHS compliance status and MSL rating for supply chain and assembly compatibility

The identified substitute part 796638-6 (TE Connectivity AMP Connectors) meets these core substitution criteria through matching pitch specification, right-angle orientation, and equivalent regulatory compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

Both the ELFH0621G and 796638-6 maintain active product status with unlimited moisture sensitivity ratings, indicating stable long-term availability and suitability for standard assembly environments. Both components carry identical ECCN and HTSUS classifications, confirming regulatory equivalence for export and tariff purposes.

The ELFH0621G is RoHS Compliant, while the 796638-6 is ROHS3 Compliant, with ROHS3 representing the current regulatory standard. Both certifications satisfy RoHS requirements for lead-free component selection in modern electronics manufacturing.

Selection between these parts should be based on:

• Availability requirements and inventory levels (796638-6 currently shows higher stock availability at 7259 pieces)
• Specific mechanical interface requirements (796638-6 specifies through-hole mounting and provides detailed dimensional data including contact tail length and insulation height)
• Thermal operating range requirements (796638-6 specifies -40°C ~ 110°C operating temperature)
• Supplier relationship and procurement lead time considerations

Frequently Asked Questions (FAQ)

Q: What makes 796638-6 a valid substitute for ELFH0621G?

A: Both components share the critical 0.200" (5.08mm) pitch specification and right-angle header orientation required for mechanical and electrical compatibility in terminal block applications. Both maintain active product status, unlimited MSL ratings, and equivalent regulatory compliance (RoHS and EAR99 classification).

Q: Are there dimensional differences between these parts?

A: The 796638-6 provides specified dimensional data including 0.138" (4.60mm) contact tail length and 0.329" (8.36mm) insulation height. The ELFH0621G dimensional specifications are not provided in the available data. Physical verification is necessary when exact dimensional matching is required for specific PCB layouts.

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

A: ROHS3 represents the current iteration of the RoHS directive with updated substance restrictions. Both certifications satisfy lead-free component requirements. ROHS3 Compliant status indicates compliance with the most current regulatory standard.

Q: Can these parts be used interchangeably in existing designs?

A: Substitution is valid when the design accommodates the specified pitch (0.200"/5.08mm) and right-angle orientation. The 796638-6 specifies through-hole mounting, solder termination, and detailed electrical ratings (15 A at 300 V per UL standard). Verification of these specifications against original design requirements is necessary before implementation.

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

A: MSL 1 (Unlimited) indicates these components have unlimited shelf life and do not require special moisture-controlled storage or handling procedures, simplifying supply chain management and reducing storage costs.
