TE Connectivity 103735-7 Rectangular Connector Header – Equivalent & Substitute Parts

Part Overview

The TE Connectivity 103735-7 is a vertical rectangular connector header manufactured under the AMPMODU MTE series. This through-hole connector features 8 positions with 0.100" (2.54mm) pitch spacing, designed for board-to-board or cable interconnection applications. The connector is shrouded with 4-wall construction and incorporates a keying slot for polarization control.

The 103735-7 is classified as an active product and is suitable for automotive, general purpose, medical, and telecommunications applications. Identifying equivalent substitute parts is necessary when the primary part number becomes unavailable, when supply chain optimization is required, or when compliance requirements necessitate alternative sourcing.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TE Connectivity 103735-7 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Connector Type: Header
• Contact Type: Male Pin
• Number of Positions: 8
• Number of Rows: 1
• Pitch - Mating: 0.100" (2.54mm)
• Mounting Type: Through Hole
• Shrouding: Shrouded - 4 Wall
• Termination: Solder
• Contact Shape: Square
• Current Rating: 3A
• Operating Temperature Range: -65°C ~ 105°C
• Material Flammability Rating: UL94 V-0
• Insulation Material: Thermoplastic
• Contact Material: Brass
• Fastening Type: Latch Holder
• Features: Keying Slot

The substitute part 5-103735-7 meets all mandatory matching parameters and is therefore classified as a direct equivalent. This part maintains identical mechanical and electrical specifications while differing only in compliance status and contact finish post material composition.

Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity 5-103735-7 is a direct functional equivalent to the 103735-7 for all electrical and mechanical applications. Both parts are active products manufactured by TE Connectivity within the AMPMODU MTE series and maintain identical specifications across connector type, contact configuration, pitch, mounting method, and performance ratings.

Compliance Considerations:

The primary distinction between these parts is regulatory compliance status. The 5-103735-7 is ROHS3 compliant, whereas the 103735-7 is RoHS non-compliant. For applications subject to RoHS directives or customer specifications requiring RoHS compliance, the 5-103735-7 is the appropriate selection.

The contact finish on the post differs between the two parts: the 103735-7 uses Tin-Lead while the 5-103735-7 uses Tin. Both finishes maintain identical thickness specifications (100.0µin / 2.54µm) and are suitable for solder termination applications.

Both parts carry identical electrical ratings (3A current capacity), operating temperature range (-65°C to 105°C), and UL94 V-0 flammability certification. Mechanical dimensions, shrouding configuration, and keying features are identical.

Selection between these parts should be based on regulatory requirements applicable to the end application and supply chain availability. Both parts are classified as active products with current manufacturing status.

Frequently Asked Questions (FAQ)

Q: Are the 103735-7 and 5-103735-7 mechanically interchangeable?

A: Yes. Both parts are identical in all mechanical dimensions, mounting configuration, and physical form factor. They are pin-for-pin compatible and can be used interchangeably in board designs without modification.

Q: What is the difference between the contact finishes on these parts?

A: The 103735-7 features Tin-Lead contact finish on the post, while the 5-103735-7 uses Tin. Both finishes are applied at identical thickness (100.0µin / 2.54µm). The mating contact finish (Gold) is identical on both parts. The post finish difference reflects the RoHS compliance status of each part.

Q: Which part should I specify for new designs?

A: Selection depends on regulatory requirements. If RoHS3 compliance is required, specify the 5-103735-7. If RoHS compliance is not a requirement, either part is acceptable based on availability and supply chain considerations.

Q: Are both parts suitable for automotive applications?

A: Yes. Both the 103735-7 and 5-103735-7 are listed for automotive applications. Both maintain the required operating temperature range (-65°C to 105°C) and UL94 V-0 flammability rating for automotive use.

Q: What is the current rating for these connectors?

A: Both parts are rated for 3A continuous current per contact. This rating applies to all 8 positions in the connector.

Q: Can these connectors be used in medical applications?

A: Yes. Both parts are specified for medical applications and maintain appropriate certifications and material specifications for this use.

Q: What is the pitch spacing of these connectors?

A: Both connectors feature 0.100" (2.54mm) pitch spacing between contacts. This is the standard spacing for these AMPMODU MTE series headers.

Q: Are these parts moisture sensitive?

A: Both parts carry Moisture Sensitivity Level (MSL) rating of 1, which indicates unlimited shelf life with no special moisture control requirements during storage or handling.

Q: What is the shrouding configuration?

A: Both parts feature shrouded construction with 4-wall shrouding. This provides mechanical protection and aids in proper mating alignment.

Q: Do these connectors include keying features?

A: Yes. Both parts incorporate a keying slot feature for polarization control, preventing incorrect mating orientation.
