Molex 0705510048 Rectangular Connector - Equivalent & Substitute Parts

Part Overview

The Molex 0705510048 is a shrouded right-angle header connector with 14 positions at 2.54mm pitch, designed for through-hole mounting in board-to-cable/wire applications. This connector features male pins with gold-plated mating contacts and tin-plated posts, suitable for automotive, industrial, medical, and general-purpose applications. The part is currently active in production with full inventory availability and ROHS3 compliance. Substitute parts are identified to provide alternative sourcing options when the primary part is unavailable or when design flexibility permits equivalent component selection.

Key Parameters

Substitute Part Grouping Explanation

The TE Connectivity AMP Connectors part number 6-103673-3 qualifies as a direct substitute based on the following critical parameters:

• Connector Type & Contact Configuration: Both parts are shrouded headers with male pins and 14 positions
• Pitch Specification: Identical 0.100" (2.54mm) mating pitch ensures mechanical and electrical compatibility
• Mounting & Termination: Both feature through-hole, right-angle mounting with solder termination
• Contact Finish: Both utilize gold-plated mating contacts and tin-plated posts
• Compliance & Safety: Both are ROHS3 compliant with UL94 V-0 flammability rating and MSL 1 moisture sensitivity
• Application Scope: Both support automotive, general-purpose, industrial, and medical applications

Substitution is valid where the design accommodates minor variations in contact length, insulation material composition, and operating temperature range extensions.

Parameter Comparison

Engineering Selection Recommendations

Both the Molex 0705510048 and TE Connectivity 6-103673-3 are active production parts with equivalent functional specifications for 14-position, 2.54mm pitch right-angle header applications. Selection between these parts may be based on:

• Inventory Availability: Molex 0705510048 has 946 units in stock; TE Connectivity 6-103673-3 has 1823 units available
• Packaging Format: Molex ships in bulk; TE Connectivity ships in tube packaging
• Temperature Range: TE Connectivity part extends lower temperature operation to -65°C versus -40°C for Molex
• Contact Material: Molex uses phosphor bronze; TE Connectivity uses brass
• Insulation Material: Molex uses polyester glass-filled; TE Connectivity uses thermoplastic
• Current Rating: TE Connectivity specifies 3A; Molex does not specify current rating
• Voltage Rating: Molex specifies 250V; TE Connectivity does not specify voltage rating

Both parts maintain ROHS3 compliance, UL94 V-0 flammability rating, and MSL 1 moisture sensitivity classification. Selection should account for specific application requirements regarding temperature extremes, current handling, and voltage stress.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 6-103673-3 directly replace the Molex 0705510048 in existing designs?

A: Yes, for applications within the overlapping operating temperature range (-40°C to 105°C) and voltage/current specifications. The 14-position, 2.54mm pitch configuration, shrouded 4-wall design, and solder termination are identical. Minor dimensional variations in contact length and insulation height are within typical connector tolerance ranges.

Q: What are the key differences between these two parts?

A: Primary differences include contact material (phosphor bronze vs. brass), insulation material (polyester glass-filled vs. thermoplastic), and specified electrical ratings. The TE Connectivity part offers extended lower temperature operation (-65°C) and specifies 3A current rating, while the Molex part specifies 250V voltage rating.

Q: Are both parts suitable for automotive applications?

A: Yes, both parts list automotive applications and maintain equivalent compliance certifications (ROHS3, UL94 V-0, MSL 1).

Q: What is the significance of the packaging difference (bulk vs. tube)?

A: Packaging format affects handling, storage, and order quantities but does not impact electrical or mechanical performance. Bulk packaging typically suits high-volume manufacturing; tube packaging provides organized component management for smaller quantities.

Q: Do these connectors require mating connectors from the same manufacturer?

A: No. Both parts are standard 2.54mm pitch headers designed to mate with any compatible 2.54mm pitch connector socket or receptacle meeting the same electrical and mechanical specifications.

Q: What is the significance of the keying slot feature on the TE Connectivity part?

A: The keying slot on the TE Connectivity 6-103673-3 provides polarization capability to prevent incorrect mating orientation. The Molex part does not specify this feature. This difference should be evaluated based on application requirements for mating security.
