Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MSTB 2,5/ 4-G-THT P16 R32 is determined by the following critical parameters:

• Number of Positions and Pitch: Both main and substitute parts must maintain 4 positions at 0.197" (5.00mm) pitch to ensure mechanical and electrical compatibility with existing PCB layouts and mating connectors.
• Header Orientation: The 90° right-angle configuration is mandatory for maintaining the same mounting profile and spatial requirements.
• Termination Style: Solder termination is required for direct replacement in through-hole applications.
• Electrical Ratings: Substitute parts must meet or exceed the IEC current (12A) and voltage (250V) specifications to ensure safe operation within the original circuit design parameters.
• Compliance Standards: RoHS compliance and UL94 V-0 flammability rating are essential for regulatory and safety requirements.

The Phoenix Contact CCA 2,5/ 4-G P20 THR R56 (part number 1836599) qualifies as a substitute based on these criteria, with enhanced electrical ratings and active product status.

Engineering Selection Recommendations

The CCA 2,5/ 4-G P20 THR R56 (1836599) is suitable for direct substitution of the obsolete MSTB 2,5/ 4-G-THT P16 R32 (1708281) based on the following engineering criteria:

• Electrical Compatibility: The substitute part maintains the required 12A IEC current rating and exceeds the voltage specification (320V vs. 250V), providing additional safety margin in the circuit design.
• Mechanical Compatibility: Both parts share identical pitch (5.00mm), position count (4), and right-angle orientation, ensuring compatibility with existing PCB footprints and mating connectors.
• Regulatory Compliance: Both parts are RoHS compliant and carry UL94 V-0 flammability certification, meeting the same regulatory and safety standards.
• Product Status: The substitute part is active in the Phoenix Contact product line, ensuring long-term availability and supply chain stability compared to the obsolete main part.
• Shrouding Difference: The substitute features 4-side shrouding compared to 2-side shrouding on the main part. This enhanced shrouding provides improved EMI shielding and mechanical protection, representing a functional improvement without compromising compatibility.

Frequently Asked Questions (FAQ)

Q: Can the CCA 2,5/ 4-G P20 THR R56 be used as a direct replacement for the MSTB 2,5/ 4-G-THT P16 R32?

A: Yes. Both parts maintain identical pitch (5.00mm), position count (4), and right-angle orientation. The substitute meets or exceeds all electrical specifications (12A current, 320V voltage vs. 250V) and carries equivalent compliance certifications (RoHS, UL94 V-0).

Q: What is the difference between 2-side and 4-side shrouding?

A: The main part features shrouding on 2 sides, while the substitute features shrouding on all 4 sides. The 4-side configuration provides enhanced EMI shielding and mechanical protection without affecting electrical or mechanical compatibility with the mating connector.

Q: Are there packaging differences between these parts?

A: The main part is supplied in standard packaging, while the substitute is supplied in Tape & Reel (TR) format. This affects handling and assembly processes but does not impact the electrical or mechanical performance of the component.

Q: Does the higher voltage rating (320V vs. 250V) on the substitute part affect compatibility?

A: No. Higher voltage ratings indicate improved electrical performance and safety margins. The substitute part is fully compatible with circuits designed for the original 250V specification.

Q: What is the operating temperature range for the substitute part?

A: The CCA 2,5/ 4-G P20 THR R56 operates from -40°C to 100°C, providing a defined thermal operating window for system design considerations.
