Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1705701 is determined by strict alignment with the following critical parameters:

• Position Count & Pitch: Must be 4 positions at 0.200" (5.08mm) spacing
• Physical Configuration: Vertical orientation, through-hole mounting, male pins with 4-side shrouding
• Electrical Ratings: Minimum 12A current capacity and voltage ratings meeting or exceeding IEC 200V / UL 300V
• Termination & Finish: Solder termination with tin contact mating finish
• Mechanical Dimensions: Contact tail length 0.154" (3.90mm) and insulation height 0.472" (12.00mm)

The Phoenix Contact 1704833 qualifies as a direct substitute based on these parameters. Both components share identical mechanical and electrical specifications within the allowed tolerance range, with the 1704833 offering the additional advantage of active product status.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1704833 is the appropriate substitute for the obsolete 1705701. Both components are manufactured by Phoenix Contact and maintain identical mechanical and electrical specifications across all critical parameters. The 1704833 provides enhanced IEC voltage rating (250V versus 200V), representing a performance improvement over the original specification.

The primary distinction between these components is product lifecycle status: the 1705701 is obsolete, while the 1704833 maintains active production status. This status difference ensures long-term component availability and continued manufacturer support for the 1704833.

Both components carry identical ECCN (EAR99) and HTSUS (8536.69.4040) classifications, confirming regulatory and trade compliance alignment.

Frequently Asked Questions (FAQ)

Q: Can the 1704833 be used as a direct replacement for the 1705701 in existing designs?

A: Yes. The 1704833 is mechanically and electrically compatible with the 1705701. All critical parameters—position count, pitch, orientation, mounting type, current rating, and physical dimensions—are identical. The components are pin-compatible and footprint-compatible for PCB applications.

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

A: Both series designations refer to Phoenix Contact terminal block product lines. The 1705701 belongs to the EMSTBVA series (obsolete), while the 1704833 belongs to the MSTBVA series (active). The functional and electrical characteristics remain equivalent for substitution purposes.

Q: Does the higher IEC voltage rating of the 1704833 (250V vs. 200V) affect compatibility?

A: No. A higher voltage rating indicates improved electrical performance and does not compromise compatibility. The 1704833 can safely operate in applications designed for the 1705701 without modification.

Q: Are there any packaging or inventory considerations?

A: Both components are available in stock. The 1705701 has 1081 pieces in inventory (obsolete status), while the 1704833 has 1109 pieces available (active status). For new designs and ongoing procurement, the 1704833 is the recommended choice due to its active product status.

Q: What certifications apply to both components?

A: Both the 1705701 and 1704833 carry identical ECCN (EAR99) and HTSUS (8536.69.4040) classifications, confirming compliance with export control and tariff regulations.
