Phoenix Contact 1859629 Terminal Block Header - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1859629 is a 13-position terminal block header with male pins, shrouded on four sides, featuring a 0.200" (5.08mm) pitch for vertical through-hole mounting. This component is classified as obsolete, making identification of functionally equivalent substitute parts essential for ongoing system maintenance and new design implementations.

The primary reason for identifying substitutes is the obsolete product status of the main part. Active equivalent models from the same manufacturer provide identical or compatible electrical and mechanical characteristics while ensuring continued availability and supply chain reliability.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1859629 terminal block header is determined by the following critical parameters:

Mandatory Matching Parameters:

• Number of Positions: 13
• Pitch: 0.200" (5.08mm)
• Header Orientation: Vertical
• Mounting Type: Through Hole
• Type: Header, Male Pins, Shrouded (4 Side)
• Current - IEC: 12A
• Current - UL: 12 A
• Contact Mating Finish: Tin
• Material Flammability Rating: UL94 V-0
• Insulation Height: 0.472" (12.00mm)

Allowable Variation Parameters:

• Termination Style: Press-Fit or Solder acceptable
• Housing Material: PBT, Polyamide (PA/Nylon), or Liquid Crystal Polymer (LCP)
• Contact Tail Length: 0.102" to 0.154" (2.60mm to 3.90mm)
• Voltage - IEC: 250 V minimum
• Voltage - UL: 300 V minimum
• Product Status: Active preferred for supply continuity
• RoHS Compliance: RoHS Compliant or ROHS3 Compliant

Both identified substitute parts (1755846 and 1827883) meet all mandatory matching parameters and fall within allowable variation ranges.

Parameter Comparison

Engineering Selection Recommendations

Part 1755846 (COMBICON MSTBVA Series): This substitute offers active product status with enhanced voltage rating (630 V IEC vs. 320 V IEC on the main part). The solder termination style differs from the press-fit design of the original part, requiring PCB layout adjustment. Housing material is polyamide (PA/Nylon) instead of PBT. Contact tail length matches the original specification at 0.154" (3.90mm). ROHS3 compliance exceeds the RoHS Compliant status of the main part. This option provides superior voltage performance and active supply availability.

Part 1827883 (COMBICON CCVA Series): This substitute provides active product status with solder termination. Housing material is liquid crystal polymer (LCP), offering different thermal and mechanical properties compared to the original PBT design. Contact tail length is shorter at 0.102" (2.60mm), which may require PCB footprint verification. Voltage rating is 250 V IEC, meeting minimum substitution criteria. RoHS compliance matches the original part. This option is suitable for applications where the shorter contact tail and LCP material properties are compatible with system requirements.

Both substitutes maintain identical electrical performance in terms of current rating (12A) and contact configuration (13 positions, 5.08mm pitch, vertical through-hole, shrouded male pins). Selection between these options depends on termination method compatibility with existing PCB designs and housing material requirements.

Frequently Asked Questions (FAQ)

Q: Can part 1755846 directly replace the 1859629 in existing designs?

A: Part 1755846 is electrically and mechanically compatible as a substitute. However, the termination style differs (solder vs. press-fit), requiring PCB footprint verification. The housing material change from PBT to polyamide (PA/Nylon) may affect thermal performance in specific applications. Voltage rating is higher (630 V IEC), providing additional margin.

Q: What is the primary difference between the two substitute parts?

A: Part 1755846 features a longer contact tail (0.154" / 3.90mm) and polyamide housing with higher voltage rating (630 V IEC). Part 1827883 has a shorter contact tail (0.102" / 2.60mm) and liquid crystal polymer (LCP) housing with lower voltage rating (250 V IEC). Both use solder termination and maintain the 13-position, 5.08mm pitch configuration.

Q: Is the contact tail length difference between 1827883 and the original part significant?

A: Yes. Part 1827883 has a contact tail length of 0.102" (2.60mm) compared to 0.154" (3.90mm) on the original 1859629. This 0.052" (1.30mm) difference requires PCB hole depth and solder joint geometry verification before implementation.

Q: Do all three parts meet the same flammability and RoHS requirements?

A: All three parts meet UL94 V-0 flammability rating. RoHS compliance status is equivalent: the main part and 1827883 are RoHS Compliant, while 1755846 is ROHS3 Compliant, which represents an updated compliance standard.

Q: Which substitute is recommended for new designs?

A: Selection depends on termination method compatibility and housing material requirements. Part 1755846 offers superior voltage performance (630 V IEC) and active supply status. Part 1827883 provides active supply status with standard voltage rating (250 V IEC). Both are suitable for new designs; choose based on PCB assembly process and thermal requirements.

Q: Are there packaging differences between the main part and substitutes?

A: The main part 1859629 is listed with unspecified packaging. Substitutes 1755846 and 1827883 are supplied in bulk packaging. Verify minimum order quantities and packaging requirements with your supplier.
