Phoenix Contact 1709698 Terminal Block Header - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1709698 is a 2-position terminal block header with male pins, shrouded on 4 sides, designed for 0.200" (5.08mm) pitch vertical through-hole mounting. This component belongs to the COMBICON EMSTBVA series and is rated for 12A at 320V (IEC). The part is currently obsolete, making identification of suitable substitute components essential for ongoing system maintenance and new design implementations.

Substitute Part Grouping Explanation

Substitution of the Phoenix Contact 1709698 is determined by strict alignment of the following critical parameters:

Position Count & Pitch: Both substitute parts maintain 2 positions at 0.200" (5.08mm) pitch, ensuring mechanical and electrical compatibility with existing PCB layouts and mating connectors.
Type & Shrouding: All parts feature male pins with 4-side shrouding, preserving the same form factor and safety characteristics.
Mounting Configuration: Vertical through-hole mounting is maintained across all parts, allowing direct PCB integration without redesign.
Electrical Ratings: Substitute parts meet or exceed the 12A current and 320V voltage requirements of the original component.
Contact Geometry: Insulation height (0.472" / 12.00mm) is identical across all parts. Contact tail length variations are noted but do not prevent substitution when PCB pad layouts accommodate the specified dimensions.

The two identified substitutes (1792737 and 1809267) differ primarily in termination style (solder vs. press-fit), housing material, and product status (active vs. obsolete), but maintain full electrical and mechanical compatibility.

Engineering Selection Recommendations

For Active Production and New Designs:

Both substitute parts (1792737 and 1809267) are active components with superior compliance profiles compared to the obsolete 1709698. Selection between them depends on termination method requirements:

1792737 (COMBICON CCV): Solder termination with UL94 V-0 flammability rating and Liquid Crystal Polymer (LCP) housing. RoHS compliant. Suitable for applications requiring solder-based assembly and enhanced material properties. Contact tail length of 0.102" (2.60mm) requires PCB pad verification.
1809267 (COMBICON MSTBVA): Solder termination with UL94 V-0 flammability rating and Polybutylene Terephthalate (PBT) housing. ROHS3 and REACH compliant. Maintains the original 0.154" (3.90mm) contact tail length, minimizing PCB layout modifications. Supports higher UL current rating (15A vs. 10A for 1792737).

For Legacy System Maintenance:

The 1709698 press-fit termination style differs from both substitutes, which employ solder termination. If press-fit mounting is mandatory, alternative sourcing strategies or custom assembly may be required. Both substitutes provide higher voltage ratings (400V vs. 320V), offering improved safety margins.

Frequently Asked Questions (FAQ)

Q: Can 1792737 or 1809267 directly replace 1709698 in existing assemblies?

A: Mechanical and electrical compatibility is confirmed for both substitutes. However, termination style differs: 1709698 uses press-fit, while 1792737 and 1809267 require solder attachment. PCB pad design and assembly process must accommodate solder termination. Contact tail length variation in 1792737 (0.102" vs. 0.154") requires PCB pad depth verification.

Q: What are the key differences between 1792737 and 1809267?

A: Both are solder-terminated, 2-position, 5.08mm pitch headers with identical electrical ratings (12A IEC, 400V IEC). Primary differences: 1792737 uses LCP housing with 0.102" contact tail; 1809267 uses PBT housing with 0.154" contact tail (matching original). 1809267 supports higher UL current (15A vs. 10A). 1809267 includes REACH compliance documentation.

Q: Are there compliance or regulatory differences?

A: Both substitutes carry UL94 V-0 flammability ratings and RoHS compliance. 1792737 is RoHS compliant; 1809267 is ROHS3 compliant with REACH Unaffected status. Both share EAR99 ECCN and 8536.69.4040 HTSUS classification with the original part.

Q: Which substitute is recommended for new PCB designs?

A: 1809267 is recommended for new designs due to matching contact tail length (0.154"), eliminating PCB pad redesign, and superior compliance documentation (ROHS3, REACH). Higher UL current rating (15A) provides additional design margin.

Q: Can I use press-fit termination with these substitutes?

A: No. Both 1792737 and 1809267 are solder-terminated only. Press-fit capability is exclusive to the original 1709698. Assembly process must transition to wave or reflow soldering.
