Key Parameters

Substitute Part Grouping Explanation

Substitution of terminal block headers is determined by strict equivalence across the following critical parameters:

Mechanical Compatibility:

• Number of positions (7)
• Pitch spacing (0.197" / 5.00mm)
• Header orientation (Vertical)
• Mounting type (Through Hole)
• Contact tail length (0.138" / 3.50mm)
• Insulation height (0.079" / 2.00mm)

Electrical Compatibility:

• Voltage rating (300 V UL minimum)
• Current rating (12 A UL minimum)
• Termination style (Solder)

Compliance & Environmental:

• Material flammability rating (UL94 V-0)
• RoHS3 compliance
• Moisture sensitivity level (MSL 1)

The Phoenix Contact 1933231 qualifies as a substitute part because it maintains all critical mechanical dimensions, meets or exceeds electrical ratings, and satisfies all compliance requirements specified for the TE Connectivity 1546931-7.

Parameter Comparison

Engineering Selection Recommendations

Primary Part: TE Connectivity 1546931-7

The TE Connectivity AMP Connectors 1546931-7 is the specified component and remains the first choice when availability and design continuity are priorities. This part is active in production status with established supply (844 units in stock) and carries full ROHS3 compliance and EAR99 export classification.

Substitute Part: Phoenix Contact 1933231

The Phoenix Contact 1933231 serves as a direct functional equivalent for the TE Connectivity 1546931-7. Both components share identical mechanical dimensions, pitch spacing, and mounting characteristics. The Phoenix Contact substitute meets all electrical requirements with UL ratings of 16 A at 300 V, exceeding the primary part's 12 A specification. Both parts carry UL94 V-0 flammability certification, ROHS3 compliance, and MSL 1 moisture sensitivity rating.

The Phoenix Contact 1933231 additionally provides IEC electrical ratings (12 A at 400 V), offering broader international compliance documentation. This substitute is suitable for applications where the TE Connectivity part is unavailable or where supply chain diversification is required.

Compliance Verification:

Both parts satisfy identical compliance frameworks:

• RoHS3 Directive compliance
• UL94 V-0 material flammability rating
• MSL 1 moisture sensitivity (unlimited shelf life)
• EAR99 export classification
• HTSUS commodity code 8536.69.4040

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 1933231 be used as a direct replacement for the TE Connectivity 1546931-7?

A: Yes. The Phoenix Contact 1933231 maintains identical mechanical dimensions (7 positions, 5.00mm pitch, vertical orientation, through-hole mounting) and meets or exceeds all electrical specifications. Both components feature solder termination, tin contact finish, and identical insulation geometry.

Q: Are there any differences in electrical performance between these parts?

A: The Phoenix Contact 1933231 provides higher current capacity (16 A UL versus 12 A UL) and includes IEC electrical ratings (12 A at 400 V) not specified for the TE Connectivity part. Both maintain 300 V UL voltage rating. These differences represent performance enhancements rather than limitations.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the TE Connectivity 1546931-7 and Phoenix Contact 1933231 are ROHS3 compliant, carry UL94 V-0 flammability certification, and maintain MSL 1 moisture sensitivity rating. Both are classified as EAR99 for export purposes and share the same HTSUS commodity code.

Q: What are the critical dimensions that must match for substitution?

A: Substitution requires identical pitch (0.197" / 5.00mm), number of positions (7), contact tail length (0.138" / 3.50mm), and insulation height (0.079" / 2.00mm). Both parts meet these requirements exactly.

Q: Are there packaging or inventory considerations?

A: The TE Connectivity 1546931-7 is available in bulk packaging with 844 units in stock. The Phoenix Contact 1933231 is also available in bulk packaging with 1082 units in stock. Both are active production items.

Q: Can these parts be used interchangeably in existing PCB designs?

A: Yes. The identical mechanical specifications (pitch, contact tail length, insulation height, and through-hole mounting) ensure direct PCB footprint compatibility. No design modifications are required for substitution.

Q: What is the difference between the Buchanan and COMBICON PST series?

A: These represent different product series from different manufacturers. The Buchanan series is TE Connectivity's designation, while COMBICON PST is Phoenix Contact's series designation. Despite different series names, the parts maintain identical electrical and mechanical specifications for this 7-position 5.00mm pitch configuration.
