Substitute Part Grouping Explanation

Substitute parts for the TE Connectivity 796643-7 terminal block are identified based on the following critical parameters that determine functional compatibility:

Primary Compatibility Criteria:

• Number of Positions: 7 (all substitutes maintain this requirement)
• Type: Header, Male Pins, Shrouded (4 Side) (all substitutes match this configuration)
• Mounting Type: Through Hole (all substitutes use through-hole mounting)
• Termination Style: Solder (all substitutes use solder termination)
• Voltage Rating (UL): 300 V minimum (all substitutes meet or exceed this specification)
• Flammability Rating: UL94 V-0 (all substitutes comply with this standard)
• Housing Material: Polyamide/Nylon (all substitutes use compatible materials)

Pitch Grouping: Substitutes are organized into two pitch categories:

1. 5.00mm Pitch Group (0.197"): Parts 1755561 (Phoenix Contact) and 796643-7 (TE Connectivity) share identical 5.00mm pitch spacing, enabling direct mechanical and electrical interchange.

2. 5.08mm Pitch Group (0.200"): Parts 0395311007 (Molex) and 1755781 (Phoenix Contact) operate at 5.08mm pitch spacing. While this represents a 0.08mm difference from the main part, both groups maintain the same 7-position configuration and electrical ratings, allowing substitution based on PCB layout requirements.

All substitute parts maintain Active product status and comply with RoHS and environmental regulations. Current ratings vary between 12 A (Phoenix Contact) and 15 A (Molex and TE Connectivity), with all ratings sufficient for standard terminal block applications.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection (Direct Substitution - 5.00mm Pitch):

The Phoenix Contact 1755561 terminal block is the primary substitute for the TE Connectivity 796643-7. Both components share identical 0.197" (5.00mm) pitch spacing, enabling direct mechanical and electrical interchange without PCB layout modifications. Both parts maintain Active product status, UL94 V-0 flammability compliance, and RoHS3 certification. The 1755561 operates at 12 A (UL), which is lower than the 796643-7 rating of 15 A; however, this rating remains suitable for standard terminal block applications. The identical insulation height of 0.472" (12.00mm) and tin contact mating finish ensure compatibility with existing connector systems.

Secondary Selection (5.08mm Pitch Alternative):

The Molex 0395311007 and Phoenix Contact 1755781 terminal blocks operate at 0.200" (5.08mm) pitch spacing, representing a 0.08mm deviation from the main part. These components are suitable for applications where PCB layout accommodates the slightly wider pitch. The Molex 0395311007 maintains the 15 A current rating of the original part and operates across -40°C to 105°C, providing thermal performance comparable to the 796643-7. The Phoenix Contact 1755781 operates at 12 A (UL) and 630 V (IEC), offering enhanced voltage capability under IEC standards. Both 5.08mm pitch alternatives maintain Active product status, UL94 V-0 compliance, and RoHS3 certification.

Compliance and Regulatory Considerations:

All substitute parts comply with RoHS3 standards and maintain Moisture Sensitivity Level 1 (Unlimited), eliminating special handling requirements. The TE Connectivity 796643-7 carries RoHS Compliant status, while all substitutes carry ROHS3 Compliant status, indicating enhanced environmental compliance. All parts are classified under ECCN EAR99 and HTSUS 8536.69.4040, maintaining consistent export and tariff classifications.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 1755561 directly replace the TE Connectivity 796643-7 without PCB modifications?

A: Yes. Both components share identical 0.197" (5.00mm) pitch spacing and 7-position configuration. The 1755561 maintains the same insulation height (0.472"), mounting type (through-hole), and termination style (solder). Direct substitution is possible without PCB layout changes.

Q: What is the difference between the 5.00mm and 5.08mm pitch groups?

A: The 5.00mm pitch group (796643-7 and 1755561) maintains 0.197" spacing between positions, while the 5.08mm pitch group (0395311007 and 1755781) uses 0.200" spacing. The 0.08mm difference requires PCB layout verification before substitution. Both groups maintain identical 7-position configuration and electrical ratings.

Q: Are the Phoenix Contact substitutes rated for the same current as the TE Connectivity 796643-7?

A: The TE Connectivity 796643-7 is rated at 15 A (UL), while both Phoenix Contact substitutes (1755561 and 1755781) are rated at 12 A (UL). The Phoenix Contact parts also carry IEC ratings of 12 A. The 12 A rating is suitable for standard terminal block applications and remains within acceptable operating parameters for most industrial equipment.

Q: Do all substitute parts comply with the same flammability and environmental standards?

A: Yes. All substitute parts maintain UL94 V-0 flammability rating and comply with RoHS3 standards. All parts carry Moisture Sensitivity Level 1 (Unlimited), eliminating special storage or handling requirements. All parts are classified under ECCN EAR99 for export purposes.

Q: What is the contact material difference between the main part and substitutes?

A: The TE Connectivity 796643-7 uses Copper Alloy contacts, while the Molex 0395311007 uses Brass contacts. Phoenix Contact parts do not specify contact material in the provided data. All parts maintain tin contact mating finish for solderability and corrosion resistance.

Q: Can I use the Molex 0395311007 if my application requires 15 A current rating?

A: Yes. The Molex 0395311007 maintains the 15 A (UL) current rating of the original TE Connectivity part. However, the 0395311007 operates at 5.08mm pitch spacing, requiring PCB layout verification before substitution.

Q: Are there any temperature operating range differences between the main part and substitutes?

A: The TE Connectivity 796643-7 operates across -40°C to 110°C, while the Molex 0395311007 operates across -40°C to 105°C. Phoenix Contact parts do not specify operating temperature ranges in the provided data. Both temperature ranges are suitable for standard industrial applications.

Q: What inventory availability should I consider when selecting a substitute?

A: Current inventory levels are: TE Connectivity 796643-7 (1,111 pcs), Phoenix Contact 1755781 (2,395 pcs), Molex 0395311007 (4,363 pcs), and Phoenix Contact 1755561 (699 pcs). Inventory availability may influence substitution decisions based on project timelines and sourcing requirements.
