Engineering Selection Recommendations
Primary Recommendation: TE Connectivity 1776146-3
The TE Connectivity 1776146-3 is the direct active-production equivalent to the obsolete 796699-3. This part maintains identical electrical specifications (15 A at 300 V UL), matching pitch (5.00mm), shrouding configuration (4-side), and operating temperature range (-40°C to 110°C). The 1776146-3 carries RoHS Compliant certification and is currently in active production status with 1031 units in stock. This part is the preferred substitution for direct replacement applications.
Secondary Recommendation: HARTING 14120316001000
The HARTING 14120316001000 provides an alternative from an active manufacturer with identical pitch (5.00mm) and shrouding (4-side). This part exceeds the voltage specification of the original (600 V UL versus 300 V UL) while maintaining the 15 A current rating and -40°C to 110°C operating temperature. ROHS3 Compliant status and active production status support its use in new designs. This part is suitable for applications requiring enhanced voltage margin.
Tertiary Recommendation: Molex 0395211003
The Molex 0395211003 matches the 5.00mm pitch and 4-side shrouding with equivalent electrical ratings (15 A at 300 V UL). This part is ROHS3 Compliant and in active production with 4537 units in stock. The operating temperature range is -40°C to 105°C, which is 5°C lower than the original specification. This part is suitable for applications where the reduced upper temperature limit is acceptable.
Pitch Variant Substitutes (5.08mm)
Parts with 5.08mm pitch (Molex 0395311003, HARTING 14120317001000, Phoenix Contact 1755749, and Phoenix Contact 1924318) represent a minor pitch tolerance variation. These parts maintain functional electrical equivalence but require mechanical layout verification to confirm PCB footprint compatibility. The 5.08mm pitch is within standard connector pitch tolerances and is widely used in industrial terminal block applications.
Compliance Considerations
All recommended substitute parts carry either RoHS Compliant or ROHS3 Compliant certification. The original 796699-3 carries "Not applicable" RoHS status due to its obsolete classification. Selection of RoHS-compliant substitutes ensures compliance with current environmental regulations and supports long-term supply chain sustainability.
Frequently Asked Questions (FAQ)
Q: Can the TE Connectivity 1776146-3 be used as a direct replacement for the 796699-3?
A: Yes. The 1776146-3 is the active-production equivalent with identical electrical ratings (15 A, 300 V UL), pitch (5.00mm), shrouding (4-side), and operating temperature range (-40°C to 110°C). The primary difference is the housing material specification (PA, Nylon versus PA66, Nylon 6/6), which does not affect functional compatibility. The 1776146-3 is the recommended primary substitute.
Q: What is the difference between 5.00mm and 5.08mm pitch parts?
A: The pitch difference represents a 0.08mm tolerance variation. Both pitches are functionally equivalent for terminal block applications. However, PCB footprints designed for 5.00mm pitch may require verification before accepting 5.08mm pitch parts. The 5.08mm pitch is standard in many industrial connector families and is widely compatible with existing designs.
Q: Are Phoenix Contact parts suitable substitutes?
A: Phoenix Contact parts (1755529, 1755749, 1924208, 1924318) are functionally equivalent in terms of electrical ratings and mechanical dimensions. However, these parts feature lower current ratings (12 A or 16 A) compared to the original 15 A specification. Phoenix Contact parts are suitable for applications where the specified current rating is not exceeded. All Phoenix Contact substitutes are ROHS3 Compliant and in active production.
Q: What does the 4-side shrouding specification mean?
A: 4-side shrouding indicates that the terminal block header is enclosed on all four sides (top, bottom, left, right), providing maximum protection and mechanical stability. Molex 0395310003 features 2-side shrouding (typically top and bottom), which provides less mechanical protection but maintains electrical equivalence. The 4-side shrouding configuration is preferred for applications requiring enhanced mechanical robustness.
Q: Are all substitute parts RoHS compliant?
A: All recommended substitute parts carry either RoHS Compliant or ROHS3 Compliant certification. The original 796699-3 is classified as "Not applicable" for RoHS status due to its obsolete designation. Selection of RoHS-compliant substitutes ensures compliance with current environmental regulations and supports supply chain continuity.
Q: What is the significance of the contact material difference (Copper Alloy versus Brass)?
A: Both Copper Alloy and Brass contact materials meet the electrical and mechanical requirements for this terminal block application. Copper Alloy is used in TE Connectivity and HARTING parts, while Brass is used in Molex parts. Both materials provide equivalent electrical conductivity and contact reliability. The choice between these materials does not affect functional compatibility.
Q: Can I use a part with a higher voltage rating than the original specification?
A: Yes. Parts with higher voltage ratings (such as HARTING 14120316001000 at 600 V UL versus the original 300 V UL) provide enhanced voltage margin and are suitable for direct substitution. The higher voltage rating does not negatively impact performance in applications designed for 300 V operation.
Q: What is the Moisture Sensitivity Level (MSL) and why is it important?
A: MSL 1 (Unlimited) indicates that the component has unlimited shelf life and does not require special moisture-controlled storage or handling. All substitute parts carry MSL 1 classification, matching the original part specification. This simplifies inventory management and reduces handling complexity.
Q: Are there any mechanical dimension differences I should be aware of?
A: The primary mechanical dimensions (pitch, insulation height, and shrouding configuration) are matched across all recommended substitutes. Minor variations exist in contact tail length (0.138" to 0.154") and insulation height tolerances (0.470" to 0.472"), which fall within standard manufacturing tolerances and do not affect PCB mounting compatibility.
