Phoenix Contact 1739279 Terminal Block Header - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1739279 is a 5-position terminal block header featuring male pins with 4-side shrouding, designed for vertical through-hole mounting with a 0.138" (4.60mm) pitch. This component operates at 8A (IEC/UL) and 160V (IEC) / 300V (UL), utilizing press-fit termination technology. The part is classified as obsolete, necessitating identification of active equivalent alternatives that maintain electrical and mechanical compatibility for new designs and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1739279 is determined by strict alignment with the following critical parameters:

• Electrical Compatibility: Current rating of 8A (IEC/UL) and voltage rating of 160V (IEC) / 300V (UL) minimum
• Mechanical Compatibility: 5-position configuration, 0.138" (4.60mm) pitch, vertical orientation, through-hole mounting
• Physical Form: Male pins with 4-side shrouding, black color
• Regulatory Compliance: RoHS compliance and MSL rating of 1

The Phoenix Contact 1800313 qualifies as a substitute based on matching all electrical and mechanical parameters. The primary difference is termination style: the 1739279 uses press-fit termination, while the 1800313 employs solder termination. Both maintain identical pitch, position count, voltage/current ratings, and physical shrouding configuration.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1800313 is the appropriate substitute for the obsolete 1739279. Both components maintain identical electrical ratings (8A, 160V IEC, 300V UL), mechanical configuration (5-position, 4.60mm pitch, vertical through-hole), and regulatory compliance (RoHS, MSL 1).

The 1800313 is currently in active production status, ensuring long-term availability and supply chain continuity. Both parts carry equivalent certifications (EAR99, HTSUS 8536.69.4040) and identical MSL ratings.

The primary design consideration is termination methodology: the 1800313 requires solder attachment rather than press-fit installation. PCB layout and assembly process compatibility must be evaluated based on your manufacturing capability and design requirements.

Frequently Asked Questions (FAQ)

Q: Can the 1800313 directly replace the 1739279 in existing designs?

A: Electrical and mechanical compatibility is confirmed. The 1800313 maintains identical pitch (4.60mm), position count (5), voltage/current ratings, and shrouding configuration. However, termination method differs: the 1800313 uses solder termination versus the 1739279's press-fit design. PCB footprint and assembly process must be verified for compatibility.

Q: What is the significance of the different contact tail lengths?

A: The 1739279 has a contact tail length of 0.150" (3.81mm), while the 1800313 measures 0.134" (3.40mm). This 0.016" difference may affect PCB hole depth requirements and solder joint formation. Verify PCB design specifications before implementation.

Q: Are both parts RoHS compliant?

A: Yes. Both the 1739279 and 1800313 are RoHS compliant with MSL rating 1 (unlimited moisture sensitivity level), meeting equivalent environmental and regulatory standards.

Q: Why is the 1739279 classified as obsolete?

A: The 1739279 is no longer in active production. The 1800313 represents the current active equivalent within the Phoenix Contact COMBICON terminal block family, ensuring availability for new designs and ongoing production requirements.

Q: Are there any differences in series designation?

A: Yes. The 1739279 belongs to the COMBICON EMCV series, while the 1800313 is part of the COMBICON MCV series. Both series share identical electrical and mechanical specifications for this 5-position configuration.
