Phoenix Contact 1915233 Terminal Block Header - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1915233 is a 4-position terminal block header with male pins, shrouded on all four sides, featuring a 0.200" (5.08mm) pitch for vertical through-hole mounting. This component is part of the COMBICON EMSTBV series and is rated for 12A at 320V (IEC) and 300V (UL). The part is currently obsolete, making identification of functionally equivalent alternatives essential for ongoing system maintenance and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1915233 is determined by the following critical parameters:

Primary Matching Criteria:

• Number of positions: 4
• Pitch: 0.200" (5.08mm)
• Header orientation: Vertical
• Type: Male pins, shrouded (4 side)
• Mounting type: Through hole
• Insulation height: 0.472" (12.00mm)

Secondary Compatibility Factors:

• Current rating (IEC/UL): Minimum 12A
• Voltage rating (UL): Minimum 300V
• Material flammability: UL94 V-0
• RoHS compliance status

The three substitute parts identified (1777099, 1792753, and 796867-4) maintain the core mechanical and electrical specifications required for direct functional replacement. Variations in termination style (solder vs. press-fit), housing material composition, and voltage ratings above the minimum threshold do not preclude substitution in applications where the original part is no longer available.

Parameter Comparison

Engineering Selection Recommendations

Phoenix Contact 1777099 is the primary substitute for the 1915233. Both components are manufactured by Phoenix Contact within the COMBICON family, share identical mechanical dimensions (4 positions, 5.08mm pitch, 12.00mm insulation height), and maintain equivalent electrical performance at 12A and 300V (UL). The 1777099 features solder termination versus the press-fit termination of the original part, and offers enhanced voltage rating (630V IEC). The part is currently in active production status with ROHS3 compliance.

Phoenix Contact 1792753 provides an alternative within the COMBICON CCV series. This part maintains the 4-position, 5.08mm pitch configuration and 300V UL rating. The contact tail length is reduced to 0.102" (2.60mm) compared to the original 0.154" (3.90mm), and the housing material is Liquid Crystal Polymer (LCP) rather than PBT. The UL current rating is 10A, which is lower than the original 12A specification. This part is suitable for applications where the reduced contact tail length and alternative housing material are compatible with the PCB layout and thermal requirements.

TE Connectivity 796867-4 (Buchanan series) is a cross-manufacturer substitute offering equivalent mechanical and electrical performance. The part maintains the 4-position, 5.08mm pitch vertical through-hole configuration with 300V UL rating and UL94 V-0 flammability rating. The UL current rating is 15A, exceeding the original specification. Housing material is Polyamide (PA66), and the contact tail length is 0.138" (4.60mm). This part is in active production with ROHS3 compliance and provides an alternative sourcing option from a different manufacturer.

Frequently Asked Questions (FAQ)

Q: Can the 1777099 directly replace the 1915233 in existing designs?

A: The 1777099 is mechanically and electrically compatible with the 1915233 for applications requiring 12A at 300V (UL). The primary difference is termination style: the 1915233 uses press-fit termination while the 1777099 uses solder termination. PCB design modifications may be required to accommodate solder pads instead of press-fit holes. Both parts share identical pitch (5.08mm), insulation height (12.00mm), and pin configuration (4 positions, male, shrouded).

Q: What is the impact of the reduced contact tail length in the 1792753?

A: The 1792753 has a contact tail length of 0.102" (2.60mm) compared to the original 1915233 at 0.154" (3.90mm). This 0.052" (1.30mm) reduction affects PCB hole depth requirements and solder joint formation. Verify that the PCB design accommodates the shorter tail length before substitution. The reduced tail length may also impact mechanical stability during insertion and soldering operations.

Q: Is the 796867-4 from TE Connectivity fully compatible with the Phoenix Contact 1915233?

A: The 796867-4 maintains mechanical compatibility (4 positions, 5.08mm pitch, 12.00mm insulation height, vertical through-hole mounting) and meets or exceeds electrical requirements (15A UL current rating, 300V UL voltage rating). The housing material differs (Polyamide PA66 versus PBT), and the contact tail length is 0.138" (4.60mm) versus 0.154" (3.90mm). Both parts carry UL94 V-0 flammability rating and RoHS compliance. Cross-manufacturer substitution is viable where sourcing from a single Phoenix Contact supplier is not feasible.

Q: What are the key differences in housing material between the substitute parts?

A: The 1915233 and 1777099 use Polybutylene Terephthalate (PBT), the 1792753 uses Liquid Crystal Polymer (LCP), and the 796867-4 uses Polyamide (PA66). All materials meet UL94 V-0 flammability requirements. LCP offers superior dimensional stability and lower moisture absorption compared to PBT. Polyamide PA66 provides good mechanical strength and thermal performance. Material selection should be verified against application-specific requirements for thermal cycling, chemical exposure, and mechanical stress.

Q: Are all substitute parts RoHS compliant?

A: Yes. The 1915233 is RoHS Compliant, the 1777099 and 796867-4 are ROHS3 Compliant, and the 1792753 is RoHS Compliant. All parts meet current RoHS directives and are suitable for applications requiring RoHS compliance documentation.

Q: What is the significance of the higher voltage rating in the 1777099?

A: The 1777099 is rated for 630V (IEC) compared to the 1915233 at 320V (IEC). Both maintain 300V (UL) rating. The higher IEC voltage rating in the 1777099 provides additional safety margin in high-voltage applications but does not change the UL-specified operating voltage. Selection should be based on the actual application voltage requirement and relevant certification standard (IEC or UL).
