TE Connectivity 2-1670730-1 Rectangular Connector Plug Housing – Equivalent & Substitute Parts

Part Overview

The TE Connectivity 2-1670730-1 is a 3-position rectangular connector plug housing from the Heavy Duty Sealed Connector Series (MCP 1.5K). This component serves as the housing assembly for sealed connector applications requiring panel mount installation with crimp contact termination. The part is currently active in production with 1462 units in stock inventory. Substitute parts are identified to provide alternative sourcing options when the primary part number is unavailable or when specific design requirements necessitate alternative configurations within the same electrical and mechanical parameter set.

Substitute Part Grouping Explanation

Substitute parts for the 2-1670730-1 are identified based on strict equivalence across the following critical parameters:

Connector Type & Position Count: Plug housing with 3 positions
Contact Pitch & Spacing: 0.157" (4.00mm) pitch, single row configuration
Contact Interface: Tab contact type with crimp termination
Mechanical Installation: Panel mount with slide-on fastening
Material & Environmental Ratings: PBT glass-filled insulation, sealed design, -40°C to 140°C operating range
Regulatory Compliance: ROHS3 compliant, MSL 1 rating

The substitute part 1-1670730-1 maintains identical electrical and mechanical parameters across all critical dimensions and functional characteristics. The primary difference is the housing color (black versus gray) and the connector manufacturer designation (Deutsch Connectors versus AMP Connectors), both operating within the same MCP 1.5K series specification.

Engineering Selection Recommendations

Both the primary part 2-1670730-1 and substitute part 1-1670730-1 are active production components with ROHS3 compliance and MSL 1 ratings, indicating full regulatory alignment for industrial and commercial applications. Selection between these parts should be based on the following criteria:

Primary Part (2-1670730-1): Select when gray housing color is specified in design documentation or when AMP Connectors brand designation is required by procurement standards.

Substitute Part (1-1670730-1): Select when black housing color is acceptable or preferred, when Deutsch Connectors sourcing is advantageous, or when the substitute provides superior inventory availability. The substitute maintains identical electrical performance and mechanical compatibility across all sealed connector interface specifications.

Both parts support the same contact pitch, termination method, operating temperature range, and sealed environmental protection. No performance degradation occurs when substituting between these part numbers within the MCP 1.5K series specification.

Frequently Asked Questions (FAQ)

Q: Are the 2-1670730-1 and 1-1670730-1 mechanically interchangeable?

A: Yes. Both housings maintain identical pitch (0.157" / 4.00mm), position count (3), contact type (tab), mounting configuration (panel mount), and fastening method (slide-on). They are mechanically interchangeable within the MCP 1.5K series specification.

Q: What is the only functional difference between these two part numbers?

A: The housing color differs: 2-1670730-1 is gray, while 1-1670730-1 is black. All electrical, mechanical, and environmental parameters are identical.

Q: Can I use the black housing (1-1670730-1) in an application designed for the gray housing (2-1670730-1)?

A: Yes, provided that housing color is not a specified design requirement. The black housing maintains all electrical and mechanical compatibility. Verify design documentation to confirm color is not a functional or aesthetic requirement.

Q: Do both parts support the same operating temperature range?

A: Yes. Both the 2-1670730-1 and 1-1670730-1 operate across -40°C to 140°C and are rated for identical environmental sealing and moisture protection (MSL 1).

Q: Are both parts RoHS compliant?

A: Yes. Both the primary and substitute parts are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity ratings, suitable for unrestricted storage and handling.

Q: What is the contact termination method for both parts?

A: Both parts use crimp termination with tab contact type. Contacts are not included with the housing and must be sourced separately and crimped according to TE Connectivity specifications.

Q: Which part has better inventory availability?

A: The substitute part 1-1670730-1 has 1638 units in stock compared to 1462 units for the primary part 2-1670730-1, providing a 176-unit inventory advantage.
