Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1796555 is determined by strict equivalence across the following critical parameters:

• Electrical Ratings: Current (12A IEC) and voltage (250V IEC) must match exactly
• Physical Configuration: 2-position count, 0.200" (5.08mm) pitch, vertical orientation, and through-hole mounting must be identical
• Connector Type: Male pins with 4-side shrouding required
• Termination Method: Solder termination only
• Material and Compliance: Polyamide housing, UL94 V-0 flammability rating, and RoHS compliance must be maintained
• Contact Specifications: Contact tail length (0.154" / 3.90mm) and insulation height (0.472" / 12.00mm) must be preserved

The substitute part 1796555-1 (Phoenix Contact 1796322) meets all these criteria and is classified as active, making it a direct functional equivalent suitable for replacement in applications currently using the obsolete 1796555.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1796322 is the recommended substitute for the obsolete 1796555. Both components share identical electrical ratings (12A, 250V), physical dimensions, and mechanical specifications. The 1796322 maintains full compliance with UL94 V-0 flammability requirements and RoHS directives.

The primary distinction is product status: the 1796555 is obsolete, while the 1796322 is active and currently manufactured. The 1796322 belongs to the related COMBICON MSTBV series, which represents the current production line for this connector family. Selection of the 1796322 ensures long-term supply chain stability and access to manufacturer support.

Both parts are suitable for applications requiring 2-position, 5.08mm-pitch terminal block headers with male pins and through-hole solder termination in industrial control, power distribution, and signal routing applications.

Frequently Asked Questions (FAQ)

Q: Can the 1796322 be used as a direct replacement for the 1796555 in existing designs?

A: Yes. The 1796322 is electrically and mechanically equivalent to the 1796555 across all specified parameters: 2-position configuration, 5.08mm pitch, 12A/250V ratings, through-hole mounting, and solder termination. No design modifications are required.

Q: What is the difference between the COMBICON MSTBVA and COMBICON MSTBV series?

A: The MSTBVA series (1796555) is obsolete. The MSTBV series (1796322) is the current production equivalent. Both series share identical electrical and mechanical specifications for this 2-position header configuration.

Q: Are there any packaging differences between these parts?

A: The 1796555 was supplied in standard packaging. The 1796322 is supplied in bulk packaging. Both are suitable for manufacturing and assembly processes.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the 1796555 and 1796322 are UL94 V-0 rated and RoHS compliant, meeting identical regulatory requirements for flammability and hazardous substance restrictions.

Q: What is the contact tail length, and why is it important?

A: Both parts have a contact tail length of 0.154" (3.90mm). This dimension determines solder joint depth and PCB hole engagement, ensuring proper electrical connection and mechanical stability in through-hole applications.

Q: Can these parts be used in high-temperature applications?

A: Operating temperature specifications are not provided in the technical data. Consult Phoenix Contact documentation or application requirements to confirm suitability for specific temperature ranges.
