Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TE Connectivity 1-103904-9 are identified based on strict equivalence across the following critical parameters:

Primary Equivalence Criteria:

• Connector type (Header)
• Contact type (Male Pin)
• Number of positions (20)
• Pitch - mating (0.100" / 2.54mm)
• Mounting type (Through Hole, Right Angle)
• Shrouding configuration (Shrouded - 4 Wall)
• Termination method (Solder)
• Contact shape (Square)
• Flammability rating (UL94 V-0)
• Moisture sensitivity level (1 - Unlimited)

Acceptable Variation Parameters:

• Contact finish composition (Gold mating surface with Tin or Tin-Lead post finish)
• Contact material (Brass or Phosphor Bronze)
• Insulation material (Thermoplastic or Polyester Glass Filled)
• Operating temperature range (minimum -40°C, maximum 105°C or greater)
• RoHS and REACH compliance status
• Manufacturer (TE Connectivity or Molex)

Substitutes must maintain functional compatibility in board-to-board or cable interconnection applications without requiring design modifications to mating connectors or PCB layouts.

Parameter Comparison

Engineering Selection Recommendations

TE Connectivity 6-103904-9 (Direct Manufacturer Substitute)

The 6-103904-9 is a direct substitute within the TE Connectivity AMPMODU MTE series. This part maintains identical mechanical and electrical specifications to the 1-103904-9 across all critical parameters. The primary distinction is RoHS compliance status: the 6-103904-9 is RoHS Compliant, whereas the 1-103904-9 is RoHS non-compliant. Selection of the 6-103904-9 is appropriate for applications requiring RoHS compliance or when inventory of the 1-103904-9 is insufficient. Both parts feature identical contact materials (Brass), insulation composition (Thermoplastic), and operating temperature ranges (-65°C ~ 105°C).

Molex 0705530019 (Cross-Manufacturer Substitute)

The Molex 0705530019 from the SL 70553 series provides functional equivalence with notable parameter variations. This part maintains the same 20-position, 0.100" (2.54mm) pitch configuration and through-hole right-angle mounting. Key differences include:

• Operating temperature range: -40°C ~ 105°C (versus -65°C ~ 105°C for TE Connectivity parts)
• Contact material: Phosphor Bronze (versus Brass)
• Insulation material: Polyester Glass Filled (versus Thermoplastic)
• Contact finish thickness - mating: 15.0µin (0.38µm) (versus 30.0µin / 0.76µm)
• Voltage rating: 250V specified (not specified for TE Connectivity parts)
• RoHS status: ROHS3 Compliant
• REACH status: REACH Unaffected

The 0705530019 is suitable for applications where the -40°C minimum operating temperature is acceptable and where ROHS3 compliance and REACH unaffected status are required. Significantly higher inventory availability (5353 pcs) supports supply chain continuity.

Compliance Considerations

Selection between these substitutes depends on regulatory requirements:

• Applications requiring RoHS compliance: Select 6-103904-9 or 0705530019
• Applications requiring REACH unaffected status: Select 0705530019
• Applications with -65°C minimum temperature requirement: Select 1-103904-9 or 6-103904-9
• Applications with no specific compliance mandate: Any part is suitable based on availability and cost

Frequently Asked Questions (FAQ)

Q: Can the Molex 0705530019 be used in applications requiring -65°C operation?

A: No. The Molex 0705530019 has a minimum operating temperature of -40°C, which does not meet the -65°C requirement of the TE Connectivity parts. For applications requiring -65°C operation, use 1-103904-9 or 6-103904-9.

Q: What is the difference between 1-103904-9 and 6-103904-9?

A: Both parts are identical in mechanical and electrical specifications. The primary difference is RoHS compliance: 6-103904-9 is RoHS Compliant, while 1-103904-9 is RoHS non-compliant. The 6-103904-9 also features Tin post finish versus Tin-Lead in the 1-103904-9.

Q: Are the contact materials interchangeable between TE Connectivity and Molex parts?

A: Yes, for functional purposes. TE Connectivity parts use Brass contacts, while the Molex 0705530019 uses Phosphor Bronze. Both materials provide equivalent electrical conductivity and mechanical performance in this connector application. Contact finish (Gold mating surface with Tin or Tin-Lead post) is the primary factor in electrical performance.

Q: Does the Molex 0705530019 have a current rating specification?

A: The Molex 0705530019 does not specify a current rating in the provided data. The TE Connectivity parts specify 3A. For applications requiring explicit current rating confirmation, contact the manufacturer or consult detailed datasheets.

Q: Can these connectors be used interchangeably with existing mating connectors?

A: Yes. All three parts maintain the same 20-position, 0.100" (2.54mm) pitch configuration with square contact geometry and shrouded 4-wall construction. They are mechanically and electrically compatible with standard 0.100" (2.54mm) pitch receptacle connectors.

Q: What is the significance of the Moisture Sensitivity Level (MSL) rating?

A: All three parts have MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. These connectors do not require special moisture control during storage, handling, or assembly.

Q: Which part should be selected for new designs?

A: For new designs, the Molex 0705530019 or TE Connectivity 6-103904-9 are preferred due to RoHS compliance status. Selection between these depends on operating temperature requirements (-40°C minimum for Molex versus -65°C minimum for TE Connectivity) and REACH compliance needs.
