Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MSTBVA 2,5/ 6-G THT R56 is determined by the following critical parameters:

• Electrical Compatibility: Current and voltage ratings must meet or exceed the original specification (12A IEC / 250V IEC minimum)
• Physical Compatibility: 6-position configuration, 0.197" (5.00mm) pitch, vertical through-hole mounting, and male pin header type
• Connector Type: Shrouded (4-side) header design for mechanical alignment and safety
• Termination Method: Solder termination for PCB integration
• Regulatory Compliance: RoHS compliance status

The substitute part CCVA 2,5/ 6-G P20 THR R56 (Manufacturer Part Number: 1837297) meets all critical substitution criteria while offering enhanced electrical ratings and active product status.

Engineering Selection Recommendations

The CCVA 2,5/ 6-G P20 THR R56 (1837297) is the qualified substitute for the obsolete MSTBVA 2,5/ 6-G THT R56 (1704844). Selection rationale is based on the following factors:

• Electrical Performance: The substitute meets all minimum electrical requirements with enhanced IEC voltage rating (320V vs. 250V) and UL current rating (16A vs. 12A), providing improved operational margin
• Physical Compatibility: Identical 6-position, 5.00mm pitch configuration with vertical through-hole mounting ensures direct PCB footprint compatibility
• Product Status: The substitute is active in production, ensuring long-term availability and supply chain continuity
• Regulatory Compliance: Both parts maintain RoHS compliance status, meeting environmental and safety standards
• Mechanical Design: Both components feature shrouded (4-side) male pin headers with tin-plated contacts, maintaining connector integrity and contact reliability

Frequently Asked Questions (FAQ)

Q: Can the CCVA 2,5/ 6-G P20 THR R56 be used as a direct replacement for the MSTBVA 2,5/ 6-G THT R56?

A: Yes. Both components share identical pitch (5.00mm), position count (6), orientation (vertical), and mounting method (through-hole solder). The substitute meets or exceeds all electrical specifications of the original part.

Q: What are the key differences between these two parts?

A: The primary differences are product status (obsolete vs. active), IEC voltage rating (250V vs. 320V), UL current rating (12A vs. 16A), and packaging format (bulk vs. tape & reel). The substitute offers enhanced electrical performance and active production status.

Q: Are there any mechanical compatibility concerns when substituting these parts?

A: No mechanical compatibility issues exist. Both parts feature identical shrouded (4-side) male pin header design, 5.00mm pitch, and vertical through-hole termination. PCB footprints are directly compatible.

Q: Does the substitute part maintain RoHS compliance?

A: Yes. The CCVA 2,5/ 6-G P20 THR R56 is RoHS compliant, matching the compliance status of the original MSTBVA part.

Q: What is the significance of the packaging difference (bulk vs. tape & reel)?

A: The original part is supplied in bulk packaging, while the substitute is supplied in tape & reel format. This difference affects procurement and assembly processes but does not impact electrical or mechanical performance.
