Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1779864 is determined by the following critical parameters:

Primary Compatibility Criteria:

• 5-position configuration with female sockets
• Pitch tolerance: 5.00mm (0.197") nominal, with 5.08mm (0.200") acceptable within mechanical tolerance
• Screw-type termination (rising cage clamp or equivalent)
• Free-hanging in-line mounting orientation
• Wire gauge compatibility: 12-30 AWG minimum support
• Electrical ratings: minimum 15A (UL) / 300V (UL)
• Housing material: Polyamide (PA) or equivalent
• Flammability: UL94 V-0 or equivalent

Identified Substitutes:

Molex 0395305105 qualifies as a substitute based on matching 5-position configuration, 5.08mm pitch (within tolerance), screw termination, free-hanging mounting, 15A (UL) / 300V (UL) ratings, and polyamide housing. Pitch variance of 0.08mm (0.003") is within mechanical tolerance for connector systems.

On Shore Technology OSTTJ057150 qualifies as a substitute based on matching 5-position configuration, 5.00mm pitch (exact match), screw termination, free-hanging mounting, 300V (UL) rating, and polyamide housing with UL94 V-0 flammability rating.

Parameter Comparison

Engineering Selection Recommendations

Phoenix Contact 1779864 remains the primary specification for applications requiring exact 5.00mm pitch, IEC current rating of 12A, and IEC voltage rating of 630V. This part is active in production with full RoHS3 compliance and ROHS3 certification.

Molex 0395305105 is suitable for applications where 5.08mm pitch is mechanically acceptable and UL ratings (15A / 300V) meet system requirements. This part is active in production. Wire gauge support extends to 12-26 AWG; applications requiring 28-30 AWG support should reference the primary part or On Shore Technology alternative.

On Shore Technology OSTTJ057150 is suitable for applications requiring exact 5.00mm pitch compatibility with UL 300V rating. This part is active in production with RoHS3 compliance and UL94 V-0 flammability certification. Housing material differs (brass vs. polyamide); mechanical compatibility should be confirmed for applications with specific housing material requirements.

All three parts maintain active production status and meet core electrical and mechanical substitution criteria.

Frequently Asked Questions (FAQ)

Q: Can Molex 0395305105 be used in place of Phoenix Contact 1779864 in existing connector systems?

A: Molex 0395305105 features a 5.08mm pitch compared to the 5.00mm pitch of the Phoenix Contact part. This 0.08mm variance is within typical mechanical tolerance for terminal block systems. Compatibility depends on the mating connector specification. If the mating connector is pitch-specific to 5.00mm, substitution is not recommended without mechanical verification.

Q: What is the wire gauge limitation when using Molex 0395305105?

A: Molex 0395305105 supports 12-26 AWG wire gauge. The Phoenix Contact 1779864 and On Shore Technology OSTTJ057150 both support 12-30 AWG. Applications requiring 28-30 AWG termination should use Phoenix Contact 1779864 or On Shore Technology OSTTJ057150.

Q: Are all three parts RoHS3 compliant?

A: Phoenix Contact 1779864 and On Shore Technology OSTTJ057150 are explicitly RoHS3 compliant. Molex 0395305105 RoHS status is not specified in available documentation.

Q: What is the difference in housing material between these parts?

A: Phoenix Contact 1779864 and Molex 0395305105 use polyamide (PA) nylon housing. On Shore Technology OSTTJ057150 uses brass housing. Housing material selection affects mechanical durability, thermal properties, and environmental resistance. Application-specific requirements should determine material selection.

Q: Do all parts meet UL94 V-0 flammability requirements?

A: Phoenix Contact 1779864 and On Shore Technology OSTTJ057150 are rated UL94 V-0. Molex 0395305105 flammability rating is not specified in available documentation. Applications requiring explicit UL94 V-0 certification should use Phoenix Contact 1779864 or On Shore Technology OSTTJ057150.

Q: What is the current rating difference between IEC and UL specifications?

A: Phoenix Contact 1779864 is rated 12A (IEC) and 15A (UL). Molex 0395305105 is rated 15A (UL) only. On Shore Technology OSTTJ057150 does not specify IEC or UL current ratings. System design should reference the applicable standard (IEC or UL) and select parts meeting or exceeding the required current specification.

Q: Are screw torque specifications consistent across all three parts?

A: Phoenix Contact 1779864 specifies 0.5-0.6 Nm (4.4-5.3 Lb-In) torque. Molex 0395305105 specifies 0.56 Nm (5.0 Lb-In). On Shore Technology OSTTJ057150 specifies 0.56 Nm (5.0 Lb-In). Torque specifications should be observed during installation to ensure proper contact pressure and electrical performance.
