TE Connectivity AMP Connectors 103361-7 Equivalent & Substitute Parts

Part Overview

The TE Connectivity AMP Connectors 103361-7 is a rectangular connector header designed for through-hole, right-angle mounting applications. This connector features 9 positions with a 0.100" (2.54mm) pitch and is part of the AMPMODU Mod II series. The part is classified as obsolete, making identification of equivalent and substitute components essential for ongoing design support, maintenance, and production continuity. Substitute parts must maintain functional compatibility while meeting the electrical and mechanical requirements of the original application.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TE Connectivity 103361-7 are identified based on the following critical parameters that determine functional compatibility:

Primary Compatibility Criteria:

• Connector type (Header)
• Contact type (Male Pin)
• Number of positions (9)
• Number of rows (1)
• Mounting configuration (Through Hole, Right Angle)
• Shrouding design (Shrouded - 4 Wall)
• Termination method (Solder)
• Fastening mechanism (Push-Pull)

Secondary Compatibility Considerations:

• Pitch tolerance (mating pitch within acceptable range for board layout)
• Contact finish and material composition
• Insulation material and flammability rating
• Operating temperature range
• Current rating capacity

The Hirose Electric DF1BZ-9P-2.5DS is identified as a substitute based on matching connector type, contact configuration, position count, mounting style, shrouding, termination, and fastening type. Pitch variation (0.098" vs. 0.100") represents a minor dimensional difference that may require board layout verification for specific applications.

Engineering Selection Recommendations

TE Connectivity 103361-7 (Original Part)

The TE Connectivity 103361-7 is classified as obsolete. While 689 pieces are currently in stock, this part is no longer in active production. The part is RoHS non-compliant and carries REACH Affected status. Selection of this part is limited to applications where existing inventory must be utilized or where legacy system maintenance requires exact original component replacement.

Hirose DF1BZ-9P-2.5DS (Substitute Part)

The Hirose DF1BZ-9P-2.5DS is an active product with 4000 pieces available in inventory. This part is ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for new designs and production. The substitute maintains functional compatibility through matching connector type, contact configuration, position count, mounting style, shrouding, termination, and fastening mechanism.

Key Differences Requiring Evaluation:

The pitch difference (0.100" vs. 0.098") represents a 0.002" (0.05mm) variation that may impact board layout compatibility. Applications with tight spacing constraints or existing PCB designs must account for this dimensional difference. The operating temperature range of the substitute (-35°C ~ 105°C) is narrower than the original (-65°C ~ 105°C), limiting use in extreme low-temperature environments. Contact finish differs (gold vs. tin), which may affect signal integrity and corrosion resistance in specific environmental conditions. The substitute includes a keying slot feature not present in the original part.

For new designs, the Hirose DF1BZ-9P-2.5DS is the preferred selection due to active product status and regulatory compliance. For legacy system support, the TE Connectivity 103361-7 remains available from existing inventory.

Frequently Asked Questions (FAQ)

Q: Can the Hirose DF1BZ-9P-2.5DS be used as a direct replacement for the TE Connectivity 103361-7?

A: The Hirose part matches the critical functional parameters: 9-position header, male pin contacts, through-hole right-angle mounting, shrouded 4-wall design, solder termination, and push-pull fastening. However, the pitch difference (0.098" vs. 0.100") requires verification that existing PCB layouts accommodate the 0.002" variation. Applications with standard 2.54mm spacing may require board redesign.

Q: What is the impact of the pitch difference between these connectors?

A: The pitch difference of 0.002" (0.05mm) is minor but may be significant in applications with tight component spacing. PCB designs using standard 0.100" (2.54mm) grid spacing will require layout adjustment to accommodate the 0.098" (2.50mm) pitch of the substitute part. Mechanical fit and electrical clearance must be verified for each application.

Q: How does the operating temperature range difference affect part selection?

A: The TE Connectivity 103361-7 operates from -65°C to 105°C, while the Hirose substitute operates from -35°C to 85°C. Applications requiring operation below -35°C or above 85°C cannot use the Hirose substitute. The original part must be selected for extreme low-temperature environments or high-temperature applications exceeding 85°C.

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

A: The TE Connectivity part features gold-plated mating contacts, while the Hirose substitute uses tin plating. Gold provides superior corrosion resistance and lower contact resistance, particularly in high-reliability applications. Tin plating is suitable for standard industrial applications but may show increased oxidation in harsh environments. Signal integrity and long-term reliability may differ between these finishes.

Q: Are there regulatory compliance differences between these parts?

A: The TE Connectivity 103361-7 is RoHS non-compliant and REACH affected. The Hirose DF1BZ-9P-2.5DS is ROHS3 compliant and REACH unaffected. New designs and production systems subject to RoHS or REACH regulations must use the Hirose substitute. Legacy systems may continue using the TE Connectivity part if existing inventory is available.

Q: What does the keying slot feature on the Hirose part provide?

A: The Hirose DF1BZ-9P-2.5DS includes a keying slot feature not present on the TE Connectivity 103361-7. This feature provides mechanical polarization to prevent incorrect mating orientation. Applications requiring keyed connectors benefit from this feature; applications using non-keyed designs must ensure the keying slot does not interfere with existing mating hardware.

Q: How should I verify compatibility for my specific application?

A: Compatibility verification requires evaluation of: (1) PCB layout accommodation of the 0.002" pitch difference, (2) operating temperature range requirements, (3) contact finish requirements for signal integrity and environmental resistance, (4) regulatory compliance needs, and (5) mechanical fit with existing mating connectors or cable assemblies. Dimensional drawings and electrical specifications must be compared against application requirements.
