Key Parameters

Substitute Part Grouping Explanation

Substitution of terminal block headers is determined by strict alignment of the following critical parameters:

Mechanical Compatibility:

• Number of positions (20 positions required)
• Pitch spacing (0.138" / 3.50mm required)
• Header orientation (vertical required)
• Mounting type (through hole required)
• Shroud configuration (4-side shrouded required)
• Insulation height (0.362" / 9.20mm required)

Electrical Compatibility:

• Voltage rating (minimum 300 V UL required)
• Current rating (minimum 8 A UL required for substitution)
• Contact mating finish (tin required)
• Termination style (solder required)

Compliance & Environmental:

• Material flammability rating (UL94 V-0 required)
• RoHS compliance status (RoHS3 or equivalent required)
• Moisture sensitivity level (MSL 1 required)

The Phoenix Contact 1843787 meets all mechanical and electrical compatibility criteria for direct substitution with the TE Connectivity 2-796694-0.

Parameter Comparison

Engineering Selection Recommendations

Primary Component (TE Connectivity 2-796694-0): The TE Connectivity 2-796694-0 is an active product with RoHS compliance and UL94 V-0 flammability rating. It supports 11 A at 300 V UL and operates across -40°C to 110°C. This component is suitable for applications requiring the specified electrical and thermal performance envelope.

Substitute Component (Phoenix Contact 1843787): The Phoenix Contact 1843787 is an active product with ROHS3 compliance and UL94 V-0 flammability rating. It supports 8 A at 300 V UL. This substitute maintains mechanical and electrical compatibility with the original component. The lower current rating (8 A versus 11 A) requires circuit-level verification to confirm adequacy for the intended application. Both components share identical pitch, position count, mounting type, and shroud configuration, enabling direct mechanical and electrical substitution in through-hole PCB applications.

Both components are classified as active products with equivalent compliance certifications (EAR99, HTSUS 8536.69.4040) and unlimited moisture sensitivity tolerance (MSL 1).

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 1843787 directly replace the TE Connectivity 2-796694-0 in existing designs?

A: Direct mechanical and electrical substitution is supported. Both components feature identical 20-position, 0.138" (3.50mm) pitch vertical through-hole configuration with 4-side shrouding. Electrical compatibility is confirmed at 300 V UL and 8 A UL. Circuit designs operating at currents below 8 A support direct substitution without modification. Designs requiring the full 11 A rating of the original component require current-level assessment.

Q: What are the key mechanical differences between these components?

A: Both components share identical mechanical specifications: 20 positions, 0.138" (3.50mm) pitch, vertical orientation, through-hole mounting, and 0.362" (9.20mm) insulation height. The Phoenix Contact substitute specifies a contact tail length of 0.134" (3.40mm), while the TE Connectivity original does not specify this parameter. Housing materials differ (PA66/Nylon 6/6 versus PBT), and cosmetic color differs (blue versus green). These differences do not affect functional compatibility.

Q: Are there compliance or certification differences between the two components?

A: Both components carry UL94 V-0 flammability ratings and meet RoHS requirements (RoHS Compliant versus ROHS3 Compliant). Both are classified under identical ECCN (EAR99) and HTSUS (8536.69.4040) codes. The Phoenix Contact component carries REACH Unaffected status, while the TE Connectivity component lists REACH status as Vendor Undefined. Both components operate at MSL 1 (Unlimited moisture sensitivity).

Q: What is the current rating difference, and when does it matter?

A: The TE Connectivity 2-796694-0 is rated for 11 A UL, while the Phoenix Contact 1843787 is rated for 8 A UL. This 3 A difference is relevant only in applications where sustained current exceeds 8 A. Applications operating at or below 8 A per position are unaffected by this rating difference. Circuit design review is required to confirm current requirements before substitution in high-current applications.

Q: Do the different housing materials affect performance or reliability?

A: Both housing materials (PA66/Nylon 6/6 and PBT) carry identical UL94 V-0 flammability ratings and support the same operating temperature range (-40°C to 110°C for the original; operating temperature not specified for the substitute). Material selection does not affect electrical performance, mechanical fit, or solder termination compatibility. Both materials are standard for terminal block applications in this category.

Q: Can these components be mixed in the same assembly?

A: Mechanical and electrical compatibility supports use of both components within the same assembly. However, design documentation and bill of materials should clearly specify component selection to maintain traceability and ensure consistent performance across production batches.
