Key Parameters

Substitute Part Grouping Explanation

Substitution of the OSTH413705B is determined by strict alignment of the following critical parameters:

• Position Count & Pitch: Both main and substitute parts must maintain 13 positions at 0.197" (5.00mm) pitch to ensure mechanical and electrical compatibility with mating connectors
• Connector Type: Female socket plugs with screwless push-in spring termination are required to maintain interface compatibility
• Mounting Configuration: Free-hanging in-line mounting must be preserved
• Electrical Ratings: Voltage rating of 300V UL and wire gauge support of 12-26 AWG establish the baseline electrical compatibility envelope
• Flammability & Compliance: UL94 V-0 material rating and RoHS compliance status ensure regulatory and safety standard alignment

The Phoenix Contact 1974847 qualifies as a direct substitute based on these parameters. While this part introduces enhanced electrical specifications (630V IEC, 12A IEC current rating) and additional certifications, these represent improvements that do not compromise backward compatibility with the original OSTH413705B application requirements.

Engineering Selection Recommendations

The Phoenix Contact 1974847 is the qualified substitute for the obsolete OSTH413705B. Selection rationale is based on the following engineering criteria:

Compliance & Regulatory Status: The 1974847 maintains active product status with current RoHS compliance certification, ensuring long-term availability and regulatory alignment for new designs and system updates. The OSTH413705B, classified as obsolete, presents supply chain risk and potential regulatory gaps in future applications.

Electrical & Safety Equivalence: Both parts satisfy the 300V UL voltage requirement and support 12-26 AWG wire gauges. The 1974847 provides enhanced electrical specifications (630V IEC, 12A IEC current) that exceed the original part's requirements without introducing incompatibility. Both maintain UL94 V-0 flammability ratings, ensuring equivalent safety performance.

Mechanical & Interface Compatibility: Identical position count (13), pitch spacing (5.00mm), connector type (female socket plug), termination method (screwless push-in spring), and mounting configuration (free-hanging in-line) guarantee direct mechanical substitution without redesign or adapter requirements.

Supply Chain Continuity: With 691 units in active inventory and active manufacturing status, the 1974847 provides reliable component availability for both immediate replacement needs and future procurement cycles.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 1974847 be used as a direct replacement for the OSTH413705B without circuit modifications?

A: Yes. The 1974847 maintains identical position count, pitch spacing, connector type, and termination method. The enhanced electrical ratings (630V IEC vs. unspecified IEC rating on the original) represent improvements that do not require circuit redesign. Mechanical fit and electrical interface compatibility are preserved.

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

A: The OSTH413705B is obsolete with limited remaining inventory, while the Phoenix Contact 1974847 is an active product with current manufacturing and full RoHS compliance certification. The 1974847 also specifies enhanced electrical performance (12A IEC current rating, 630V IEC voltage) and includes additional mechanical specifications (10mm wire strip length, 15.00mm insulation height).

Q: Are there any wire gauge or voltage limitations when substituting?

A: No. Both parts support 12-26 AWG wire gauges and 300V UL voltage ratings. The 1974847's additional IEC ratings (630V, 12A) do not impose restrictions on applications designed for the original OSTH413705B specifications.

Q: What packaging format is the substitute available in?

A: The Phoenix Contact 1974847 is supplied in bulk packaging, consistent with standard terminal block component distribution for industrial applications.

Q: Are both parts RoHS compliant?

A: Yes. The OSTH413705B is ROHS3 compliant, and the Phoenix Contact 1974847 is RoHS compliant. Both meet current regulatory requirements for hazardous substance restrictions.
