Engineering Selection Recommendations

Primary Recommendation: TE Connectivity 1776146-2

The TE Connectivity 1776146-2 is the direct equivalent replacement for the obsolete 796699-2. This part maintains identical electrical specifications (15 A UL, 300 V UL), mechanical dimensions (0.197" pitch, 0.472" insulation height), and contact configuration (male pins, 4-side shrouded). The 1776146-2 is active in production status and RoHS Compliant, providing continuity with the original design while meeting current regulatory requirements.

Secondary Recommendations for 5.00mm Pitch Applications:

Phoenix Contact 5433011 and Assmann WSW Components A-TB500-OQ02CV both maintain the 0.197" (5.00mm) pitch specification with 4-side shrouding and UL94 V-0 flammability rating. The 5433011 matches the original 15 A UL current rating, while the A-TB500-OQ02CV provides enhanced current capacity at 20 A UL. Both parts are ROHS3 Compliant and active in production.

Alternative Recommendations for 5.08mm Pitch Applications:

Molex 0395311002 and 0395316002, along with Phoenix Contact 1755736 and Assmann WSW Components A-TB508-OQ02CV, provide functional substitution with 0.200" (5.08mm) pitch. These parts maintain 4-side shrouding, 300 V UL rating, and UL94 V-0 flammability. The Molex parts and Assmann component support 15 A UL current, while Phoenix Contact 1755736 operates at 12 A UL. All parts are ROHS3 Compliant and active in production.

Compliance Considerations:

All recommended substitute parts carry ROHS3 Compliant or RoHS Compliant certification, addressing regulatory requirements for new designs. The original 796699-2 carries "Not applicable" RoHS status due to its obsolete classification. Selection of active, compliant alternatives ensures compatibility with current procurement and environmental standards.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 1776146-2 be used as a direct replacement for 796699-2?

A: Yes. The 1776146-2 maintains identical electrical ratings (15 A UL, 300 V UL), pitch (0.197"), mounting type (through-hole solder), and mechanical configuration (2-position, male pins, 4-side shrouded). The primary difference is product status (active versus obsolete) and RoHS compliance. Physical and electrical compatibility is complete.

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

A: Pitch refers to the center-to-center distance between adjacent positions. The 0.197" (5.00mm) pitch and 0.200" (5.08mm) pitch represent a 0.003" (0.08mm) tolerance variation. While mechanically similar, these pitches are not interchangeable in applications with tight spacing constraints. Verify PCB layout compatibility before substitution.

Q: Are Molex 0395310002 and 0395311002 interchangeable?

A: Both parts share 0.200" (5.08mm) pitch, 2-position configuration, and 15 A UL / 300 V UL ratings. The primary difference is shrouding: 0395310002 features 2-side shrouding while 0395311002 features 4-side shrouding. Selection depends on application requirements for EMI shielding and mechanical protection. They are not directly interchangeable if shrouding configuration is specified.

Q: Why do Phoenix Contact parts show lower current ratings (12 A UL) compared to the original 796699-2 (15 A UL)?

A: Phoenix Contact 1755516 and 1755736 are rated at 12 A UL, which is lower than the original 15 A specification. These parts are suitable for applications operating at or below 12 A. For applications requiring the full 15 A capacity, select TE Connectivity 1776146-2, Molex 0395211002, 0395311002, 0395316002, Phoenix Contact 5433011, or Assmann WSW Components A-TB500-OQ02CV and A-TB508-OQ02CV.

Q: What does "4-side shrouded" mean?

A: 4-side shrouding indicates that the terminal block header has insulating material on all four sides (top, bottom, left, right), providing enhanced mechanical protection and EMI shielding compared to 2-side shrouded designs. The original 796699-2 and most recommended substitutes feature 4-side shrouding. Molex 0395310002 is an exception with 2-side shrouding.

Q: Are all substitute parts RoHS compliant?

A: All recommended substitute parts carry ROHS3 Compliant or RoHS Compliant certification. The original 796699-2 shows "Not applicable" RoHS status due to its obsolete classification. For new designs and procurement, all listed active alternatives meet current RoHS requirements.

Q: What is the significance of contact tail length variation?

A: Contact tail length affects solder joint depth and PCB hole engagement. The original 796699-2 specifies 0.138" (3.50mm). Substitute parts range from 0.130" (3.30mm) to 0.157" (4.00mm). Verify PCB design accommodates the selected part's contact tail length to ensure proper solder joint formation and mechanical stability.

Q: Can I use Assmann WSW Components A-TB500-OQ02CV in place of 796699-2?

A: Yes, with enhanced specifications. The A-TB500-OQ02CV maintains 0.197" (5.00mm) pitch, 4-side shrouding, and identical mechanical dimensions. It exceeds the original specifications with 20 A UL current capacity (versus 15 A) and extended operating temperature range (-40°C to 115°C versus -40°C to 110°C). This part is suitable for applications requiring higher current capacity or wider temperature operation.

Q: What is the difference between "Eurostyle" and "Buchanan" series designations?

A: Series designations identify product families within manufacturer portfolios. Buchanan is the TE Connectivity series for the original 796699-2. Eurostyle is the Molex series designation for their terminal block offerings. These are different product families with distinct design lineages, though they maintain compatible electrical and mechanical specifications for substitution purposes.
