Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity 749019-1 is based on electrical and mechanical compatibility within the D-Sub high-density connector category. The following parameters establish substitution eligibility:

Critical Matching Parameters:

• Connector type: D-Sub, high-density plug with male pins
• Position count: 78 positions
• Row configuration: 4 rows
• Shell size: 5 (DD, D) high-density layout
• Termination: Solder-based connection
• Contact material: Brass with gold plating
• Dielectric material: Polybutylene Terephthalate (PBT)
• Flammability rating: UL94 V-0

Allowable Variations:

• Mounting configuration: Through-hole and panel-mount variants are functionally compatible
• Current rating: Substitute parts with equal or higher current capacity (≥2A) are acceptable
• Voltage rating: Substitute parts with equal or higher voltage specification are acceptable
• Operating temperature range: Substitute parts with equal or wider temperature range are acceptable
• Contact finish thickness: Flash or thicker gold plating is acceptable
• Shielding features: Additional shielding is acceptable as an enhancement

The NorComp Inc. 180-078-113R011 meets all critical matching parameters and qualifies as a direct substitute.

Parameter Comparison

Engineering Selection Recommendations

The NorComp Inc. 180-078-113R011 is an active substitute for the obsolete TE Connectivity 749019-1. Selection criteria are based on the following factors:

Product Status Consideration: The TE Connectivity 749019-1 is classified as obsolete, making the NorComp 180-078-113R011 the appropriate active alternative for new designs and ongoing procurement requirements.

Electrical Compatibility: The NorComp substitute provides a current rating of 3A, exceeding the 2A specification of the original part. Both connectors utilize identical brass contact material with gold plating and maintain the same shell material and nickel plating specification. The dielectric material composition is compatible, with both parts meeting UL94 V-0 flammability requirements.

Mechanical Compatibility: Both connectors share identical D-Sub high-density configuration with 78 positions arranged in 4 rows, shell size 5 (DD, D) layout, and solder termination. The NorComp part offers panel-mount capability in addition to through-hole mounting, providing installation flexibility.

Compliance Status: The NorComp 180-078-113R011 is ROHS3 compliant and REACH unaffected, addressing modern regulatory requirements. The original TE Connectivity part is RoHS non-compliant, making the substitute preferable for applications subject to environmental compliance mandates.

Temperature Operating Range: The NorComp substitute operates across -50°C to 100°C, which is slightly narrower than the original -55°C to 105°C range. Applications requiring operation below -50°C or above 100°C require specific evaluation against system requirements.

Frequently Asked Questions (FAQ)

Q: Can the NorComp 180-078-113R011 directly replace the TE Connectivity 749019-1 in existing assemblies?

A: Yes. Both connectors share identical D-Sub high-density configuration, 78-position layout, 4-row arrangement, shell size 5 (DD, D) specification, and solder termination. The mechanical and electrical interfaces are compatible. The NorComp part provides enhanced current capacity (3A versus 2A) and additional shielding features.

Q: What is the significance of the operating temperature range difference?

A: The TE Connectivity original operates from -55°C to 105°C, while the NorComp substitute operates from -50°C to 100°C. The substitute has a narrower range at both extremes. Applications requiring operation below -50°C or above 100°C must be evaluated against specific system thermal requirements.

Q: Does the flash gold plating on the NorComp connector provide equivalent contact performance?

A: Both connectors utilize brass contact material with gold plating. The TE Connectivity part specifies 30.0µin (0.76µm) thickness, while the NorComp part specifies flash plating. Flash plating provides adequate contact protection for signal-level applications. Contact resistance and durability are determined by the underlying brass material and plating composition, which are equivalent between both parts.

Q: What is the difference between through-hole and panel-mount configurations?

A: The TE Connectivity 749019-1 is through-hole only, requiring solder connection through printed circuit board holes. The NorComp 180-078-113R011 supports both panel-mount and through-hole configurations, offering installation flexibility. Panel-mount capability allows direct mounting to connector panels or enclosures without requiring PCB integration.

Q: Are there compliance differences between the two connectors?

A: Yes. The NorComp 180-078-113R011 is ROHS3 compliant and REACH unaffected, meeting current environmental regulations. The TE Connectivity 749019-1 is RoHS non-compliant. For applications subject to environmental compliance requirements, the NorComp substitute is the appropriate selection.

Q: What does the shielded feature on the NorComp connector provide?

A: The NorComp 180-078-113R011 includes shielding in addition to the grounding indents present on both connectors. Shielding reduces electromagnetic interference (EMI) and radio frequency interference (RFI) susceptibility, providing enhanced signal integrity in electrically noisy environments. This is an enhancement over the original part.

Q: Is the higher current rating of the NorComp connector a concern for compatibility?

A: No. The NorComp 180-078-113R011 is rated for 3A, exceeding the 2A specification of the TE Connectivity original. Higher current capacity does not create compatibility issues. Applications drawing 2A or less operate within the NorComp connector's specifications with margin.

Q: What packaging format is the NorComp substitute supplied in?

A: The NorComp 180-078-113R011 is supplied in tray packaging, suitable for automated assembly and component handling processes.
