Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TE Connectivity 1776140-8 are grouped based on the following critical parameters that determine functional equivalence:

Primary Substitution Criteria:

• Number of positions: 8
• Mounting type: Through hole
• Termination style: Solder
• Header orientation: 90° right angle
• Male pin configuration
• Shrouded design (2 or 4 side)
• Current rating: 15 A (UL)
• Voltage rating: 300 V (UL)
• Material flammability: UL94 V-0
• RoHS3 compliance

Secondary Variation Parameters:

• Pitch tolerance: 0.197" (5.00mm) or 0.200" (5.08mm)
• Shroud configuration: 2-side or 4-side
• Contact material: Copper alloy or brass
• Housing material: Polyamide (PA) or Polyamide (PA66)
• Contact tail length variations
• Insulation height variations
• Operating temperature range variations

Parts are considered substitutable when they maintain identical electrical ratings (15 A / 300 V), identical position count (8), identical mounting and termination methods, and equivalent or superior compliance certifications. Pitch variations of 0.197" to 0.200" (5.00mm to 5.08mm) are included as substitutes due to industry-standard tolerance practices for terminal block applications.

Parameter Comparison

Engineering Selection Recommendations

All identified substitute parts maintain Active product status and ROHS3 compliance, ensuring long-term availability and regulatory alignment with the original TE Connectivity 1776140-8 component.

Direct Substitutes (Identical Pitch 0.197" / 5.00mm):

The Molex 0395226008 and Phoenix Contact 1754559 maintain the original 0.197" (5.00mm) pitch specification. The Molex 0395226008 features 4-side shrouding compared to the 2-side shrouding of the original part, providing enhanced mechanical protection. The Phoenix Contact 1754559 maintains 2-side shrouding identical to the original configuration and includes IEC current rating of 12 A at 400 V, exceeding UL specifications.

Pitch-Variant Substitutes (0.200" / 5.08mm):

The Molex 0395320008, 0395325008, and 0395326008 operate at a 0.200" (5.08mm) pitch, representing a 0.008" (0.08mm) deviation from the original specification. These parts are suitable for applications where PCB layout accommodates the pitch variation. The 0395320008 and 0395325008 maintain 2-side shrouding, while the 0395326008 provides 4-side shrouding with increased insulation height of 0.472" (12.00mm).

Compliance and Certification:

All substitute parts carry ROHS3 compliance and UL94 V-0 flammability ratings. The Phoenix Contact 1754559 includes REACH Unaffected status. Molex parts 0395226008, 0395325008, and 0395326008 carry REACH Unaffected or Vendor Undefined status. All parts maintain MSL 1 (Unlimited) moisture sensitivity classification.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0395226008 directly replace the TE Connectivity 1776140-8?

A: The Molex 0395226008 maintains identical pitch (0.197" / 5.00mm), position count (8), electrical ratings (15 A / 300 V), and compliance certifications. The primary difference is 4-side shrouding versus 2-side shrouding on the original part. Direct replacement is possible where PCB layout and connector cavity design accommodate the increased shroud dimensions.

Q: What is the significance of the pitch difference between 0.197" and 0.200"?

A: The pitch difference of 0.008" (0.08mm) represents a 0.4% variation. Molex parts 0395320008, 0395325008, and 0395326008 operate at 0.200" (5.08mm) pitch. These parts are substitutable only when PCB hole spacing and connector cavity design are compatible with the 5.08mm pitch specification. Pitch mismatch will result in improper mating and electrical failure.

Q: Are there differences in shroud configuration among the substitute parts?

A: Yes. The original TE Connectivity 1776140-8 features 2-side shrouding. Molex 0395226008 and 0395326008 provide 4-side shrouding, offering enhanced mechanical protection and strain relief. Molex 0395320008 and 0395325008, and Phoenix Contact 1754559 maintain 2-side shrouding. Shroud configuration affects PCB footprint and connector cavity compatibility.

Q: Do all substitute parts meet the same electrical specifications?

A: All substitute parts maintain 15 A current rating and 300 V voltage rating per UL specifications. The Phoenix Contact 1754559 additionally provides 12 A at 400 V per IEC specifications, exceeding the original UL ratings. Contact material varies between copper alloy (original) and brass (Molex and Phoenix Contact alternatives), with no impact on electrical performance for the specified ratings.

Q: What is the operating temperature range for substitute parts?

A: The original TE Connectivity 1776140-8 operates from -40°C to 110°C. Molex substitute parts (0395226008, 0395320008, 0395325008, 0395326008) operate from -40°C to 105°C, representing a 5°C reduction in maximum operating temperature. The Phoenix Contact 1754559 does not specify an operating temperature range in the provided data. Temperature range differences should be evaluated against application requirements.

Q: Are all substitute parts available in equivalent inventory quantities?

A: Inventory availability varies. The original TE Connectivity 1776140-8 has 873 pieces in stock. Molex 0395226008 has 4255 pieces, 0395320008 has 834 pieces, 0395325008 has 2475 pieces, and 0395326008 has 10924 pieces. Phoenix Contact 1754559 has 1221 pieces. Higher inventory levels for certain Molex variants may provide supply chain advantages.

Q: What compliance certifications apply to all substitute parts?

A: All substitute parts carry ROHS3 compliance and UL94 V-0 flammability rating. Moisture Sensitivity Level (MSL) is 1 (Unlimited) for all parts, indicating no moisture sensitivity precautions are required during storage or handling. REACH status varies: Phoenix Contact 1754559 and Molex 0395226008 and 0395325008 are REACH Unaffected; Molex 0395320008 status is not specified; Molex 0395326008 is Vendor Undefined.
