Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1776935 is determined by the following critical parameters:

• Position Count: Must be 7 positions to maintain PCB layout and connector compatibility
• Pitch Tolerance: Acceptable range is 5.00mm to 5.08mm (0.197" to 0.200"), accommodating standard metric and imperial terminal block spacing
• Header Type: Must be male pins with 4-side shrouding to ensure proper mating and mechanical protection
• Mounting Configuration: Must support vertical through-hole mounting for PCB integration
• Termination Method: Must use solder termination for compatibility with existing assembly processes
• Electrical Ratings: Minimum UL voltage rating of 300V and current rating of 12A required
• Flammability Compliance: UL94 V-0 rating mandatory for safety-critical applications
• Housing Material: PBT or equivalent polyamide materials acceptable based on thermal and chemical resistance requirements

The Molex 0395355007 qualifies as a direct substitute based on these parameters.

Parameter Comparison

Engineering Selection Recommendations

Both the Phoenix Contact 1776935 and Molex 0395355007 maintain active product status with full RoHS compliance and UL94 V-0 flammability certification. The Molex substitute provides equivalent electrical performance with a higher current rating (15A versus 12A), making it suitable for applications requiring additional current capacity. The pitch difference of 0.08mm (5.00mm versus 5.08mm) falls within acceptable tolerance for standard terminal block applications and does not compromise mechanical fit or electrical performance. Housing material differs between PBT and PA66 nylon, both of which provide adequate thermal and chemical resistance for typical industrial applications. Selection between these parts should be based on inventory availability, supplier lead times, and specific application thermal requirements.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0395355007 be used as a direct replacement for the Phoenix Contact 1776935 on existing PCBs?

A: Yes. Both components share identical position count (7), vertical orientation, through-hole mounting, solder termination, and insulation height (12.00mm). The pitch difference of 0.08mm is within acceptable tolerance for standard terminal block PCB layouts.

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

A: The 0.08mm difference represents a 1.6% variance and is standard across metric and imperial terminal block specifications. This tolerance is accommodated in PCB design guidelines for terminal block footprints and does not affect mechanical or electrical compatibility.

Q: Are there any thermal operating range differences between these parts?

A: The Phoenix Contact 1776935 does not specify an operating temperature range in the provided data. The Molex 0395355007 operates from -40°C to 115°C. For applications requiring specific thermal performance, verify the Phoenix Contact part's thermal specifications with the manufacturer.

Q: Does the higher current rating of the Molex part (15A versus 12A) affect compatibility?

A: No. Higher current ratings indicate greater capacity and do not compromise compatibility. The Molex part can safely handle applications designed for the 12A Phoenix Contact part without derating.

Q: What are the housing material implications for part selection?

A: Phoenix Contact uses PBT while Molex uses PA66 nylon. Both materials meet UL94 V-0 flammability requirements. PBT offers slightly better chemical resistance; PA66 offers better impact resistance. Material selection should align with specific environmental exposure conditions in the application.

Q: Are both parts RoHS compliant?

A: The Phoenix Contact 1776935 is confirmed RoHS compliant. The Molex 0395355007 REACH status is listed as vendor undefined in the provided data. Verify current RoHS and REACH compliance status with Molex for applications requiring full regulatory documentation.
