Engineering Selection Recommendations

HARTING 14120416002000 is a direct functional equivalent with enhanced voltage rating (600 V versus 300 V). This part is ROHS3 compliant and maintains identical pitch, position count, and orientation specifications. The inclusion of polyphthalamide (PPA) in the housing material composition provides additional material options. This substitute is suitable for applications where higher voltage tolerance is beneficial or where ROHS3 compliance is required.

Phoenix Contact 1757491 (COMBICON MSTBA series) provides full electrical compatibility with 15 A (UL) and 300 V (UL) ratings matching the original specification. The part is ROHS3 compliant and maintains identical mechanical dimensions and pitch. The green color variant is the primary visual distinction. This substitute is suitable for direct replacement in applications where color coding is not a constraint.

Phoenix Contact 1954935 (COMBICON CCA series) features a pitch of 0.200" (5.08mm), which represents a 0.003" (0.08mm) deviation from the original 0.197" (5.00mm) specification. The UL current rating is 10 A, which is lower than the original 15 A specification. The housing material is Liquid Crystal Polymer (LCP), offering different thermal and mechanical properties. This substitute is suitable only for applications where the slightly larger pitch and reduced current rating are acceptable.

Phoenix Contact 5445452 (BCH series) is a direct functional equivalent with identical pitch, position count, and orientation. The part maintains 15 A (UL) and 300 V (UL) ratings and is RoHS compliant. The green color variant is the primary distinction from the original black housing. This substitute is suitable for direct replacement in applications where color coding is not a constraint.

Frequently Asked Questions (FAQ)

Q: Can the HARTING 14120416002000 be used as a direct replacement for the TE Connectivity 1776148-4?

A: Yes. The HARTING 14120416002000 maintains identical pitch (0.197" / 5.00mm), position count (4), orientation (90° right angle), and shrouding configuration. Both parts are rated for 15 A at UL specifications and feature UL94 V-0 flammability ratings. The HARTING part provides a higher voltage rating (600 V versus 300 V), which is compatible with the original application requirements.

Q: What is the significance of the pitch difference in the Phoenix Contact 1954935?

A: The Phoenix Contact 1954935 features a pitch of 0.200" (5.08mm) compared to the original 0.197" (5.00mm). This 0.003" (0.08mm) difference affects PCB layout and connector mating compatibility. This part is suitable only for applications where the PCB design accommodates the larger pitch spacing or where mating with the original connector is not required.

Q: Are the Phoenix Contact green-colored variants (1757491 and 5445452) functionally equivalent to the black TE Connectivity original?

A: Yes, functionally equivalent. Both Phoenix Contact parts maintain identical electrical ratings (15 A at 300 V UL), pitch (0.197" / 5.00mm), position count (4), and orientation (90° right angle). The green color is a visual distinction only and does not affect electrical or mechanical performance. Color selection is determined by application requirements or design standards.

Q: What is the current rating difference in the Phoenix Contact 1954935?

A: The Phoenix Contact 1954935 is rated for 10 A (UL), which is lower than the original TE Connectivity 1776148-4 rated at 15 A (UL). This part is suitable only for applications where the maximum current requirement does not exceed 10 A per position.

Q: Are all substitute parts RoHS compliant?

A: The TE Connectivity 1776148-4 and Phoenix Contact 5445452 are RoHS compliant. The HARTING 14120416002000, Phoenix Contact 1757491, and Phoenix Contact 1954935 are ROHS3 compliant. Both compliance levels are acceptable for applications requiring RoHS certification.

Q: What is the difference between RoHS and ROHS3 compliance?

A: Both RoHS and ROHS3 designations indicate compliance with Restriction of Hazardous Substances regulations. ROHS3 represents the current version of the directive. Both compliance statuses are functionally equivalent for component selection purposes.

Q: Can the Phoenix Contact 1954935 be used in applications requiring the original operating temperature range of -40°C to 110°C?

A: The operating temperature range for the Phoenix Contact 1954935 is not specified in the provided data. Selection of this part for temperature-critical applications requires confirmation of its operating temperature specifications from the manufacturer.

Q: Are all substitute parts available in the same packaging format?

A: All parts listed are supplied in bulk packaging. Specific packaging quantities and configurations should be confirmed with the supplier for procurement purposes.

Q: What is the contact tail length difference between the original and substitute parts?

A: The TE Connectivity 1776148-4 has a contact tail length of 0.126" (3.20mm). The Phoenix Contact 1757491 has 0.138" (3.50mm), and the Phoenix Contact 1954935 has 0.102" (2.60mm). The HARTING 14120416002000 and Phoenix Contact 5445452 do not specify contact tail length. These differences affect solder joint geometry and PCB hole sizing considerations.
