Key Parameters

Substitute Part Grouping Explanation

Substitution of the MSTB 2,5/ 7-GF-5,08 THT is determined by the following critical parameters:

• Number of Positions: 7 positions (fixed requirement)
• Pitch: 5.08mm (0.200") center-to-center spacing (fixed requirement)
• Mounting Type: Through-hole termination (fixed requirement)
• Electrical Ratings: Current and voltage specifications must meet or exceed original ratings
• RoHS Compliance: Substitute must maintain RoHS compliance status
• Manufacturer Consistency: Phoenix Contact components ensure design compatibility and supply chain reliability

The substitute part 1954744 meets these core substitution criteria as a 7-position terminal block with 5.08mm pitch and through-hole mounting capability.

Engineering Selection Recommendations

The Phoenix Contact TERM BLOCK HDR 7POS 90DEG 5.08MM (Part Number: 1954744) is the designated substitute for the obsolete MSTB 2,5/ 7-GF-5,08 THT. Selection of this substitute is supported by the following factors:

• Active Product Status: Part 1954744 maintains active production status, ensuring long-term availability and supply chain stability compared to the obsolete original part.
• Compliance Alignment: Both components maintain RoHS compliance and identical MSL ratings, ensuring regulatory and environmental compatibility.
• Electrical Specifications: The substitute provides defined electrical ratings (12A IEC, 400V IEC; 10A UL, 300V UL) that establish clear performance boundaries for circuit design.
• Mechanical Compatibility: Identical 7-position configuration with 5.08mm pitch and through-hole mounting ensures direct functional replacement in existing PCB layouts.
• Material Certification: UL94 V-0 flammability rating and LCP housing material provide documented material performance characteristics.

Frequently Asked Questions (FAQ)

Q: Can the TERM BLOCK HDR 7POS 90DEG 5.08MM (1954744) be used as a direct replacement for the MSTB 2,5/ 7-GF-5,08 THT (1927616)?

A: Yes. Both components share identical position count (7), pitch spacing (5.08mm), and through-hole mounting type. The substitute maintains RoHS compliance and MSL rating equivalence. Verify that the 90° right-angle orientation of part 1954744 is compatible with your PCB layout requirements.

Q: What is the primary reason for substitution?

A: The original MSTB 2,5/ 7-GF-5,08 THT is classified as obsolete. The substitute part 1954744 is in active production, providing reliable long-term availability.

Q: Are the electrical ratings of the substitute adequate?

A: The substitute provides specified electrical ratings of 12A per position (IEC) at 400V and 10A (UL) at 300V. Confirm these ratings meet your application requirements before implementation.

Q: Does the substitute maintain the same packaging format?

A: The original part packaging is not specified in available documentation. The substitute is supplied in bulk packaging. Verify packaging requirements for your procurement and assembly processes.

Q: Are there any orientation differences between the original and substitute?

A: The substitute features a 90° right-angle header orientation. Confirm this orientation is compatible with your existing PCB design and connector interface requirements.
