Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TE Connectivity 103634-7 is determined by the following critical parameters: connector type (header), contact type (male pin), number of positions (8), mating pitch (2.54mm), mounting configuration (through-hole, right-angle), shrouding style (4-wall), termination method (solder), and fastening type (latch holder). Parts meeting these core specifications are classified as direct or similar substitutes based on variations in contact finish, contact material, insulation material, operating temperature range, and compliance certifications. The identified substitutes maintain functional interchangeability within the specified electrical and mechanical envelope while offering alternatives in inventory availability and regulatory compliance status.

Engineering Selection Recommendations

TE Connectivity 5-103634-7 (Direct Substitute)

The 5-103634-7 is a direct substitute within the AMPMODU MTE series from TE Connectivity. This part maintains identical mechanical and electrical specifications to the 103634-7, including connector type, position count, pitch, mounting configuration, and operating temperature range. The primary distinction is the contact finish specification: the 5-103634-7 uses pure tin plating on mating contacts, whereas the 103634-7 uses tin-lead. The 5-103634-7 is RoHS Compliant, addressing regulatory requirements for applications subject to RoHS directives. Inventory availability is significantly higher at 34,753 pieces. This substitute is appropriate for applications where RoHS compliance is required or preferred.

Molex 0705530007 (Similar Substitute)

The 0705530007 from Molex SL 70553 series is a similar substitute offering functional compatibility within the core connector specifications. This part shares the same connector type, position count, pitch, mounting style, and shrouding configuration. Notable differences include contact material (phosphor bronze versus brass), insulation material (polyester glass-filled versus thermoplastic), contact finish (gold versus tin-lead), and operating temperature range (-40°C to 105°C versus -65°C to 105°C). The mating contact length is 0.240" (6.10mm) compared to 0.230" (5.84mm) in the main part, and insulation height is 0.215" (5.45mm) versus 0.200" (5.08mm). The 0705530007 provides a 250V voltage rating specification and is ROHS3 Compliant. This substitute is suitable for applications where the lower operating temperature minimum is acceptable and where the alternative material composition and contact finish are compatible with the mating connector.

Frequently Asked Questions (FAQ)

Q: Can the 5-103634-7 be used as a direct replacement for the 103634-7?

A: Yes. The 5-103634-7 maintains identical mechanical and electrical specifications including connector type, position count, pitch, mounting configuration, and operating temperature range. The primary difference is the contact finish (tin versus tin-lead) and RoHS compliance status. Substitution is valid for applications where these differences are acceptable.

Q: What are the key differences between the 103634-7 and the Molex 0705530007?

A: The 0705530007 differs in several parameters: contact material (phosphor bronze versus brass), insulation material (polyester glass-filled versus thermoplastic), contact finish (gold versus tin-lead), mating contact length (0.240" versus 0.230"), insulation height (0.215" versus 0.200"), and operating temperature minimum (-40°C versus -65°C). The Molex part specifies a 250V voltage rating. These differences may affect compatibility with specific mating connectors and application requirements.

Q: Is the Molex 0705530007 suitable for automotive applications?

A: The 0705530007 is listed for automotive, general purpose, industrial, and medical applications. However, the reduced operating temperature minimum of -40°C versus -65°C for the TE Connectivity parts may be a limiting factor for certain automotive environments. Application-specific temperature requirements must be verified.

Q: What is the significance of the contact finish differences?

A: The 103634-7 uses tin-lead plating, the 5-103634-7 uses tin plating, and the 0705530007 uses gold plating. Contact finish affects corrosion resistance, solderability, and long-term reliability. Tin-lead and tin finishes are suitable for standard solder applications. Gold plating provides enhanced corrosion resistance and is often specified for high-reliability applications. Selection depends on application requirements and mating connector specifications.

Q: Are all three parts RoHS compliant?

A: No. The 103634-7 is RoHS non-compliant. The 5-103634-7 is RoHS Compliant. The 0705530007 is ROHS3 Compliant. Applications subject to RoHS directives require either the 5-103634-7 or 0705530007.

Q: What is the difference in insulation material between these parts?

A: The 103634-7 and 5-103634-7 use thermoplastic insulation. The 0705530007 uses polyester with glass filling. Glass-filled polyester provides enhanced mechanical strength and thermal stability. Selection depends on application mechanical stress and thermal requirements.

Q: Can these connectors be used interchangeably with different mating connectors?

A: Interchangeability depends on the specific mating connector design. While all three parts share the same pitch, position count, and basic mounting configuration, differences in contact length, insulation height, and contact material may affect compatibility with specific mating connectors. Mating connector specifications must be verified before substitution.

Q: What inventory considerations should guide part selection?

A: The 103634-7 has 703 pieces in stock, the 5-103634-7 has 34,753 pieces, and the 0705530007 has 22,597 pieces. Higher inventory availability for the substitute parts may reduce lead times and supply chain risk for high-volume applications.
