Phoenix Contact 1880371 Terminal Block Header - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1880371 is a 9-position terminal block header with male pins, shrouded on four sides, featuring 0.200" (5.08mm) pitch and 90° right-angle orientation for through-hole mounting. This component is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system maintenance and new design implementations.

The primary reason for sourcing substitute parts is the obsolete product status of the 1880371. Active equivalent models maintain the same electrical and mechanical specifications while offering current availability and ongoing manufacturer support.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the Phoenix Contact 1880371 are qualified based on the following critical parameters that determine functional equivalence:

• Electrical Specifications: Current and voltage ratings (IEC and UL standards)
• Physical Configuration: 9 positions, 0.200" (5.08mm) pitch, 90° right-angle orientation
• Connector Type: Male pins with 4-side shrouding
• Mounting Method: Through-hole termination
• Compliance Standards: UL94 V-0 flammability rating, RoHS compliance, MSL rating

The two identified substitutes (1757310 and 1954993) maintain these core parameters while differing in termination style, housing material, and product status.

Parameter Comparison

Engineering Selection Recommendations

Phoenix Contact 1757310 is the primary substitute for the 1880371. Both parts maintain identical electrical specifications (12A IEC, 15A UL) and physical configuration. The 1757310 is active in production with ROHS3 compliance. The primary difference is termination style (solder versus press-fit) and housing material (polyamide versus PBT). The shorter contact tail length (0.138" versus 0.165") requires PCB layout verification for through-hole depth compatibility.

Phoenix Contact 1954993 is a secondary substitute with active product status. This part maintains IEC electrical specifications (12A) but operates at reduced UL current rating (10A versus 15A). The housing material is liquid crystal polymer (LCP), and the contact tail length is significantly shorter (0.102"). This part is suitable only for applications where UL current requirements do not exceed 10A and PCB through-hole depth accommodates the shorter tail length.

For new designs and ongoing production, the 1757310 is the preferred equivalent. The 1954993 is suitable only when UL current requirements are 10A or lower and mechanical constraints permit the shorter contact tail.

Frequently Asked Questions (FAQ)

Q: Can the 1757310 directly replace the 1880371 in existing PCB designs?

A: Electrical compatibility is confirmed. However, the contact tail length differs (0.138" versus 0.165"), requiring verification that PCB through-hole depth accommodates the shorter tail. Termination style differs (solder versus press-fit), necessitating assembly process adjustment.

Q: What is the primary limitation of the 1954993 as a substitute?

A: The UL current rating is 10A, compared to 15A for the 1880371. Applications requiring UL compliance above 10A cannot use this part. Additionally, the contact tail length (0.102") is significantly shorter, requiring PCB design verification.

Q: Are all three parts RoHS compliant?

A: Yes. The 1880371 and 1954993 are RoHS Compliant. The 1757310 is ROHS3 Compliant, which represents a more recent compliance standard and is fully compatible with RoHS requirements.

Q: Does housing material affect electrical performance?

A: Housing material does not affect the electrical specifications listed. All three parts maintain identical IEC voltage and current ratings. Housing material selection (PBT, polyamide, or LCP) affects mechanical properties, thermal performance, and chemical resistance, which are not specified in the provided parameters.

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

A: Contact tail length determines the depth of solder joint or press-fit engagement in the PCB. Shorter tail lengths (1954993 at 0.102") require shallower through-holes, while longer tails (1880371 at 0.165") require deeper through-holes. PCB design must accommodate the specific tail length of the selected part.

Q: Are there packaging differences between these parts?

A: The 1880371 packaging is listed as unspecified. Both 1757310 and 1954993 are supplied in bulk packaging. Confirm packaging requirements with your procurement specifications.
