Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0430452008 is determined by the following critical parameters:

• Connector type (Header) and contact type (Male Pin)
• Position count (20) and row configuration (2 rows)
• Mating pitch and row spacing (0.118" / 3.00mm)
• Mounting style (Surface Mount, Right Angle)
• Shrouding configuration (Shrouded - 4 Wall)
• Termination method (Solder)
• Fastening mechanism (Locking Ramp)
• Operating temperature range (-40°C ~ 105°C)
• Contact finish specifications (Gold mating surface)
• Compliance certifications (UL94 V-0, ROHS3)

The substitute part TE Connectivity AMP Connectors 5-794626-0 meets these core electrical and mechanical parameters, enabling direct functional equivalence in board-to-cable/wire applications.

Parameter Comparison

Engineering Selection Recommendations

Both the Molex 0430452008 and TE Connectivity 5-794626-0 are active production parts with ROHS3 compliance and UL94 V-0 flammability certification. Selection between these parts should be based on the following factors:

The Molex 0430452008 provides a higher voltage rating (600V versus 250V) and fixed current rating (8A). This part is supplied in Tape & Reel packaging with MSL 1 (unlimited moisture sensitivity), making it suitable for extended storage without desiccant requirements.

The TE Connectivity 5-794626-0 offers equivalent mechanical and electrical performance for applications within its 250V voltage specification. Current rating varies by wire gauge. This part is supplied in Cut Tape packaging with MSL 2 (1-year moisture sensitivity), requiring controlled storage conditions.

Both parts maintain identical mating pitch, row spacing, shrouding configuration, and contact finish specifications. Selection should prioritize voltage and current requirements of the target application, as well as packaging and storage logistics.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 5-794626-0 directly replace the Molex 0430452008 in all applications?

A: Direct replacement is valid for applications operating at 250V or below. Applications requiring the full 600V rating of the Molex part require the original specification. Both parts share identical mating pitch (0.118" / 3.00mm), row spacing, shrouding, and contact finish specifications.

Q: What are the key differences between these two connector headers?

A: The primary differences are voltage rating (Molex 600V versus TE Connectivity 250V), insulation material (Molex uses LCP glass-filled versus TE Connectivity uses Polyamide/Nylon), current rating specification (Molex fixed 8A versus TE Connectivity varies by wire gauge), and packaging format (Molex Tape & Reel versus TE Connectivity Cut Tape). Moisture sensitivity levels also differ (MSL 1 versus MSL 2).

Q: Are the mating interfaces identical between these parts?

A: Yes. Both connectors maintain 0.118" (3.00mm) mating pitch, 2-row configuration with 0.118" (3.00mm) row spacing, square contact shape, and gold-plated mating surfaces at 30.0µin (0.76µm) thickness. Mechanical and electrical mating is fully compatible.

Q: What packaging considerations apply to these parts?

A: The Molex 0430452008 is supplied in Tape & Reel (TR) format with MSL 1 rating, allowing unlimited shelf life without desiccant storage. The TE Connectivity 5-794626-0 is supplied in Cut Tape (CT) format with MSL 2 rating, requiring storage in controlled humidity conditions for up to one year.

Q: Do both parts meet the same compliance standards?

A: Yes. Both parts are ROHS3 compliant, carry UL94 V-0 flammability certification, and share identical ECCN (EAR99) and HTSUS (8536.69.4040) classifications. Operating temperature range is identical at -40°C ~ 105°C for both parts.
