Key Parameters

Substitute Part Grouping Explanation

The 940-SP-3066R manufactured by Stewart Connector qualifies as a direct substitute based on the following critical parameters:

Matching Parameters:

• Connector Type: Plug
• Number of Positions/Contacts: 6p6c (RJ11, RJ12, RJ14, RJ25)
• Shielding: Unshielded
• Termination Method: IDC
• Length: 0.525" (13.34mm)
• Housing Material: Polycarbonate (PC)
• Contact Material: Phosphor Bronze
• Contact Finish: Gold
• Color: Translucent - Clear

Electrical Compatibility: The 940-SP-3066R exceeds the electrical specifications of the TM20P-66P with a voltage rating of 150V (versus 30V) and current rating of 1.5A (versus 500mA), ensuring compatibility with the original application requirements.

Mechanical Compatibility: Both connectors accept round cable with identical physical dimensions and IDC termination methodology, enabling direct mechanical substitution.

Product Status: The 940-SP-3066R is listed as Active with substantial inventory availability (106,564 pcs), providing reliable supply continuity.

Parameter Comparison

Engineering Selection Recommendations

The 940-SP-3066R is the appropriate substitute for the obsolete TM20P-66P based on the following factors:

Product Status & Availability: The TM20P-66P is obsolete with no active manufacturing. The 940-SP-3066R is an active product with confirmed inventory of 106,564 units, ensuring supply chain reliability.

Compliance & Certifications: The 940-SP-3066R carries ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements. Both parts share EAR99 export classification.

Electrical & Mechanical Specifications: The 940-SP-3066R meets or exceeds all critical parameters of the original part. Enhanced electrical ratings (150V/1.5A versus 30V/500mA) provide additional design margin. Mechanical compatibility is confirmed through identical connector geometry, housing material, contact configuration, and IDC termination method.

Cable Compatibility Enhancement: The 940-SP-3066R accepts both solid and stranded wires, providing greater flexibility compared to the original part's solid wire specification.

Frequently Asked Questions (FAQ)

Q: Can the 940-SP-3066R directly replace the TM20P-66P in existing applications?

A: Yes. Both connectors share identical mechanical dimensions (0.525" length), housing material (polycarbonate), contact configuration (6p6c), and termination method (IDC). The 940-SP-3066R's enhanced electrical ratings ensure compatibility with applications designed for the original part.

Q: What are the key compatibility criteria for this connector substitution?

A: Substitution is valid based on matching connector type (plug), position count (6p6c), shielding (unshielded), termination method (IDC), physical length, housing material, contact material, and contact finish. The 940-SP-3066R satisfies all these criteria.

Q: Does the 940-SP-3066R support both solid and stranded wire?

A: Yes. The 940-SP-3066R is specified for round cable with both solid and stranded wires, whereas the TM20P-66P is limited to solid wires. This provides additional flexibility in cable selection.

Q: What is the packaging difference between these parts?

A: The TM20P-66P packaging is not specified. The 940-SP-3066R is supplied in bulk packaging, which is standard for modular connector distribution.

Q: Are there compliance differences between the two parts?

A: The 940-SP-3066R carries ROHS3 compliance and REACH unaffected status. The TM20P-66P compliance status is not specified. Both parts share EAR99 export classification.

Q: What electrical margin does the 940-SP-3066R provide?

A: The 940-SP-3066R is rated for 150V and 1.5A, compared to the TM20P-66P's 30V and 500mA ratings. This provides a 5x voltage margin and 3x current margin for the original application requirements.
