• Identical number of positions: 6
• Identical voltage rating: 250VAC
• Identical operating temperature range: -55°C ~ 105°C
• Identical contact type: Male Pin

Mechanical Compatibility:

• Identical mounting configuration: Through Hole, Right Angle
• Identical shrouding: Shrouded - 1 Wall
• Identical contact dimensions: 0.290" (7.37mm) mating length, 0.140" (3.56mm) post length
• Identical insulation height: 0.250" (6.35mm)
• Identical contact shape: Square

Material & Compliance:

• Identical insulation material: Polybutylene Terephthalate (PBT), Glass Filled
• Identical flammability rating: UL94 V-0
• Identical RoHS compliance: ROHS3 Compliant

Parameter Comparison

Engineering Selection Recommendations

The substitute part 3-647630-6 is the direct equivalent for the obsolete 647630-6. Selection of the substitute is based on the following engineering criteria:

Product Status: The main part 647630-6 carries an obsolete designation, indicating discontinued manufacturing and limited availability. The substitute 3-647630-6 maintains active product status with TE Connectivity, ensuring long-term supply chain reliability and continued manufacturer support.

Compliance & Certifications: Both parts maintain identical compliance certifications including ROHS3 compliance and UL94 V-0 flammability rating. Both parts carry MSL rating 1 (Unlimited), indicating no moisture sensitivity constraints during storage or handling.

Contact Finish Specification: The substitute part features a Tin contact finish compared to the Tin-Lead finish of the main part. Both finishes are functionally equivalent for the specified 250VAC, general-purpose applications within the -55°C to 105°C operating temperature range. The Tin finish of the substitute aligns with modern lead-free manufacturing standards while maintaining electrical and mechanical performance characteristics.

Electrical & Mechanical Equivalence: All critical electrical parameters (voltage rating, operating temperature, contact configuration) and mechanical parameters (pitch spacing, mounting type, contact dimensions) are identical between the main part and substitute, ensuring direct interchangeability in existing circuit designs and PCB layouts.

Frequently Asked Questions (FAQ)

Q: Can the substitute part 3-647630-6 be used as a direct replacement for the obsolete 647630-6?

A: Yes. The substitute part maintains identical electrical and mechanical specifications across all critical parameters including pitch spacing (0.100"), number of positions (6), mounting configuration (through-hole right-angle), voltage rating (250VAC), and operating temperature range (-55°C to 105°C). The parts are directly interchangeable in existing applications.

Q: What is the difference between the Tin-Lead finish of the main part and the Tin finish of the substitute?

A: Both finishes provide equivalent electrical conductivity and corrosion resistance for the specified applications.
