Key Parameters

Substitute Part Grouping Explanation

Substitution of rectangular connector receptacle housings is determined by strict alignment of electrical and mechanical parameters. The primary criteria for substitution compatibility are:

Critical Parameters for Substitution:

• Number of Positions (must equal 5)
• Connector Type (must be Receptacle)
• Contact Type (must be Female Socket)
• Contact Termination (must be Crimp)
• Number of Rows (must equal 1)
• Mounting Type (must be Free Hanging/In-Line compatible)

Secondary Parameters Affecting Substitution:

• Pitch (connector spacing: 1.50mm, 1.25mm, 1.20mm, or 1.00mm variants available)
• Fastening Type (Locking Ramp or Friction Lock mechanisms)
• Insulation Material (Thermoplastic, Polybutylene Terephthalate, Liquid Crystal Polymer, or Polyamide)
• Operating Temperature Range (application-dependent thermal requirements)
• Color (Natural or Black)

Substitute parts are grouped by pitch specification, as this parameter directly affects mechanical compatibility with mating connectors and contact pins. Parts with identical pitch (1.50mm) provide direct substitution capability. Parts with alternative pitches (1.25mm, 1.20mm, 1.00mm) require verification of mating connector compatibility and are suitable only when the application design accommodates the different spacing.

Parameter Comparison

Engineering Selection Recommendations

Direct Substitution (Identical Pitch - 1.50mm):

The Molex 0874390500 (Pico-SPOX 87439 series) is the primary direct substitute for the TE Connectivity 1775441-5. Both parts share identical pitch (1.50mm), identical number of positions (5), identical fastening type (Locking Ramp), identical color (Natural), and identical operating temperature range (-55°C ~ 105°C). Both parts are Active in product status and RoHS3 Compliant. The primary difference is insulation material composition (Polyamide/Nylon versus Thermoplastic). This substitute provides full mechanical and electrical compatibility with existing mating connectors designed for 1.50mm pitch spacing.

Alternative Pitch Substitutes (Requires Design Verification):

The Molex 0510210500 (PicoBlade 51021 series) with 1.25mm pitch and the Molex 0781720005 (Pico-EZmate 78172 series) with 1.20mm pitch are available as alternatives when application design accommodates reduced pitch spacing. These parts require verification of mating connector compatibility and are not interchangeable without corresponding changes to the mating plug connector. The Harwin M40-1100500 with 1.00mm pitch represents the smallest pitch option and similarly requires design-level compatibility assessment.

Compliance and Availability:

All substitute parts maintain Active product status and RoHS3 Compliance, ensuring suitability for current production and regulatory requirements. Inventory availability varies: Molex 0874390500 (8,373 units), Molex 0510210500 (198,472 units), Molex 0781720005 (110,021 units), and Harwin M40-1100500 (3,899 units). Selection should prioritize the direct substitute (0874390500) for applications requiring no design modification.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0874390500 be used as a direct replacement for the TE Connectivity 1775441-5?

A: Yes. The Molex 0874390500 is a direct substitute. Both parts have identical pitch (1.50mm), identical number of positions (5), identical fastening type (Locking Ramp), identical operating temperature range (-55°C ~ 105°C), and identical color (Natural). The parts are mechanically and electrically compatible with the same mating connectors and contact pins.

Q: What is the difference between the 1.50mm pitch substitute and the 1.25mm pitch substitute?

A: Pitch refers to the center-to-center spacing between adjacent contact positions. The 1.50mm pitch (0874390500) matches the original part specification, while the 1.25mm pitch (0510210500) has closer contact spacing. These are not interchangeable without corresponding changes to the mating connector. The 1.25mm pitch substitute requires verification that your mating plug connector is designed for 1.25mm spacing.

Q: Are all substitute parts RoHS Compliant?

A: Yes. The primary part (1775441-5) is RoHS Compliant, and all substitute parts are ROHS3 Compliant. All parts meet current RoHS regulatory requirements and are suitable for production environments with RoHS mandates.

Q: What is the operating temperature difference between the main part and the alternatives?

A: The TE Connectivity 1775441-5 and Molex 0874390500 both operate from -55°C to 105°C. The Molex 0510210500 operates from -40°C to 105°C (narrower low-temperature range). The Molex 0781720005 and Harwin M40-1100500 both operate from -25°C to 85°C (significantly narrower range). Selection should verify that the substitute part's operating temperature range meets your application requirements.

Q: What is the difference between Locking Ramp and Friction Lock fastening types?

A: Both fastening types secure the connector housing to the mating connector. Locking Ramp uses a ramp mechanism for engagement, while Friction Lock relies on friction-based retention. The TE Connectivity 1775441-5 uses Locking Ramp fastening. The direct substitute (Molex 0874390500) also uses Locking Ramp. Alternative pitch substitutes use Friction Lock, which may affect mating connector compatibility.

Q: Do these connector housings include contacts?

A: No. All parts listed (main part and substitutes) are connector housings only. Contacts are not included and must be ordered separately. Ensure that replacement contacts are compatible with the selected housing pitch and contact termination type (Crimp).

Q: What insulation materials are used in the substitute parts?

A: The TE Connectivity 1775441-5 uses Thermoplastic insulation. Substitute parts use Polyamide (PA/Nylon), Polybutylene Terephthalate (PBTP), or Liquid Crystal Polymer (LCP). All materials are suitable for the specified operating temperature ranges and provide equivalent electrical insulation properties for the application category.

Q: Can I use the Harwin M40-1100500 as a substitute?

A: The Harwin M40-1100500 is available as an alternative only if your application design accommodates 1.00mm pitch spacing. This part has the smallest pitch of all options and requires verification of mating connector compatibility. It is not a direct substitute without design modification.

Q: What is Moisture Sensitivity Level (MSL)?

A: MSL 1 (Unlimited) indicates that the component has no moisture sensitivity restrictions and does not require special handling, storage, or baking procedures prior to soldering or assembly. All parts listed have MSL 1 rating.
