TE Connectivity 1241809-2 Equivalent & Substitute Parts

Part Overview

The TE Connectivity 1241809-2 is a 3-position rectangular connector plug housing from the Universal MATE-N-LOK series. This connector is designed for free-hanging, in-line applications with crimp contact termination and latch holder fastening. The part is currently active in production with 854 pieces available in new original inventory stock.

Substitute parts are identified when equivalent electrical and mechanical parameters are maintained across the connector housing specifications, allowing for direct functional replacement in applications where the main part number is unavailable or inventory constraints require alternative sourcing.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TE Connectivity 1241809-2 are qualified based on the following critical parameters that determine functional interchangeability:

Electrical and Mechanical Equivalence Criteria:

• Connector type: Plug housing
• Position count: 3 positions
• Row configuration: Single row
• Mounting configuration: Free hanging, in-line orientation
• Termination method: Crimp contacts
• Fastening mechanism: Latch holder
• Operating temperature range: -55°C to 105°C
• Insulation material family: Polyamide (PA) variants
• Color specification: Natural

Series Compatibility: All substitute parts belong to the Universal MATE-N-LOK series, ensuring mechanical and electrical compatibility within the connector ecosystem.

Compliance Alignment: Substitute parts maintain RoHS compliance status and MSL Level 1 rating, supporting equivalent environmental and reliability requirements.

Parameter Comparison

Engineering Selection Recommendations

1241809-2 Primary Selection: The 1241809-2 remains the primary part number for new designs and applications where original specification compliance is required. This part maintains active production status with RoHS compliance certification.

2178473-2 Substitute Selection: The 2178473-2 qualifies as a direct substitute with equivalent mechanical and electrical parameters. This part number offers significantly higher inventory availability (1,000,400 pieces) and ROHS3 compliance status. The insulation material specification (PA66/Nylon 6/6) represents a polyamide variant within the same material family, maintaining functional equivalence across the operating temperature range of -55°C to 105°C.

1586847-1 Substitute Selection: The 1586847-1 qualifies as a parametric equivalent with all critical connector specifications matching the main part number. This part maintains active production status with ROHS3 compliance and provides intermediate inventory availability (5,375 pieces). The insulation material specification (PA/Nylon) represents the base polyamide designation, maintaining functional equivalence.

Compliance Considerations: All three part numbers maintain MSL Level 1 rating and equivalent environmental compliance frameworks. The transition from RoHS to ROHS3 compliance in substitute parts reflects current regulatory standards while maintaining backward compatibility with existing RoHS-qualified applications.

Frequently Asked Questions (FAQ)

Q: Can 2178473-2 or 1586847-1 be used as direct replacements for 1241809-2 in existing assemblies?

A: Yes. Both substitute parts maintain identical connector type, position count, row configuration, mounting type, contact termination method, fastening mechanism, and operating temperature range. The polyamide insulation material variants (PA66 and PA) are functionally equivalent within the specified temperature range.

Q: What is the difference between the insulation materials specified across these part numbers?

A: The main part specifies PA6 (Nylon 6), while 2178473-2 specifies PA66 (Nylon 6/6), and 1586847-1 specifies PA (Nylon). All three materials are polyamide-based insulation compounds that maintain equivalent electrical and mechanical properties across the -55°C to 105°C operating temperature range specified for this connector series.

Q: Are there any compatibility issues with contact pins or mating connectors?

A: No compatibility issues exist. All three part numbers are 3-position plug housings within the Universal MATE-N-LOK series with identical position counts, row configurations, and crimp termination specifications. Contacts are not included with any of these housing parts and must be sourced separately.

Q: What is the significance of the RoHS versus ROHS3 compliance difference?

A: Both RoHS and ROHS3 represent compliant status under European environmental regulations. ROHS3 reflects the current regulatory framework. Parts with either certification are suitable for applications requiring RoHS compliance. The substitute parts with ROHS3 certification align with current regulatory standards.

Q: How does inventory availability affect part selection?

A: Inventory levels are provided for reference. The 2178473-2 offers substantially higher stock (1,000,400 pieces), while 1586847-1 provides intermediate availability (5,375 pieces) compared to the main part (854 pieces). Selection should be based on application requirements and delivery timeline needs.

Q: Are these parts suitable for the same environmental conditions?

A: Yes. All three part numbers maintain identical operating temperature specifications (-55°C to 105°C) and MSL Level 1 rating (unlimited moisture sensitivity protection). They are suitable for equivalent environmental applications.

Q: What does "Contacts Not Included" mean for these housing parts?

A: These part numbers specify connector housings only. The male or female crimp contacts must be sourced separately and are not supplied with the housing. Contact selection must match the 3-position configuration and crimp termination specification.
