TE Connectivity 103688-9 Rectangular Connector Equivalent & Substitute Parts

Part Overview

The TE Connectivity 103688-9 is a 10-position rectangular connector receptacle housing with 0.100" (2.54mm) pitch, designed for free-hanging in-line mounting applications. This component belongs to the AMPMODU MTE series and operates across the temperature range of -65°C to 105°C. The part is classified as Active with RoHS Compliant status and unlimited moisture sensitivity level (MSL 1). Substitute parts are identified when equivalent electrical and mechanical parameters align with the main part specifications, enabling direct functional replacement in applications where the primary part is unavailable or when design requirements permit alternative housing materials or color configurations.

Substitute Part Grouping Explanation

Substitution eligibility for the TE Connectivity 103688-9 is determined by strict alignment of the following critical parameters: connector type (receptacle), contact type (female socket), number of positions (10), pitch (0.100"/2.54mm), number of rows (1), mounting type (free hanging in-line), contact termination method (crimp), and moisture sensitivity level (MSL 1). All identified substitute parts maintain these core electrical and mechanical specifications. Variations in insulation material composition, housing color, and operating temperature upper limits do not preclude substitution when the minimum operating temperature floor (-65°C or higher) and all positional/pitch requirements remain constant. Substitute parts are sourced from TE Connectivity AMP Connectors series variants and cross-manufacturer equivalents from Molex and Amphenol ICC (FCI).

Engineering Selection Recommendations

TE Connectivity AMPMODU MTE Series (103688-9 and 103648-9): Both parts maintain identical electrical and mechanical specifications with thermoplastic insulation material. Part 103648-9 carries ROHS3 Compliant certification compared to the RoHS Compliant status of 103688-9, offering enhanced regulatory alignment for new designs. Both operate across -65°C to 105°C and are suitable for direct substitution in existing applications.

TE Connectivity AMPMODU Series (1-926657-0 and 2-87175-2): These parts provide alternative insulation materials (PBT glass-filled and polyester glass-filled respectively) while maintaining all critical electrical and mechanical parameters. Both carry ROHS3 Compliant status. Part 1-926657-0 uses PBT glass-filled insulation; part 2-87175-2 uses polyester glass-filled insulation. Selection between these variants depends on application-specific material compatibility requirements.

TE Connectivity AMPMODU Mod IV Series (1-925366-0): This part features polyamide (PA) nylon insulation with green housing color. It maintains all core specifications and RoHS Compliant status. This variant is suitable for applications where color differentiation or nylon material properties are advantageous.

Molex SL 70066 Series (0050579210): This cross-manufacturer equivalent from Molex maintains all critical positional and pitch specifications with polyester glass-filled insulation and ROHS3 Compliant status. The operating temperature range is -40°C to 105°C, which accommodates applications not requiring the full -65°C lower limit. This part offers high inventory availability (14,672 units).

Amphenol ICC (FCI) Mini-PV™ and Basics+ Series (65039-027LF): This part provides polyphenylene modified insulation with RoHS Compliant status. Operating temperature range is -40°C to 105°C. This variant is suitable for applications where the -40°C minimum temperature threshold is acceptable.

Frequently Asked Questions (FAQ)

Q: Can I substitute 103688-9 with 103648-9 in my existing design?

A: Yes. Both parts are from the TE Connectivity AMPMODU MTE series with identical electrical and mechanical specifications: 10 positions, 0.100" pitch, female socket contacts, crimp termination, and -65°C to 105°C operating range. The primary difference is RoHS certification level (ROHS3 for 103648-9 versus RoHS Compliant for 103688-9). Substitution is direct.

Q: What is the difference between the TE Connectivity variants (103688-9, 103648-9, 1-926657-0, 1-925366-0, 2-87175-2)?

A: All maintain identical positional, pitch, and mounting specifications. Differences exist in insulation material composition and housing color: 103688-9 and 103648-9 use thermoplastic; 1-926657-0 uses PBT glass-filled; 1-925366-0 uses polyamide nylon with green color; 2-87175-2 uses polyester glass-filled. Material selection depends on application requirements for chemical resistance, mechanical strength, or thermal properties.

Q: Can I use the Molex 0050579210 as a substitute for 103688-9?

A: Yes, for applications where the operating temperature minimum of -40°C is acceptable. The Molex part maintains all critical specifications: 10 positions, 0.100" pitch, female socket contacts, crimp termination, and 105°C maximum temperature. If your application requires operation below -40°C, the TE Connectivity variants with -65°C minimum are required.

Q: What is the advantage of 65240-010LF over 103688-9?

A: The Amphenol ICC 65240-010LF extends the maximum operating temperature to 125°C compared to 103688-9's 105°C limit. All other electrical and mechanical specifications are identical. This part is suitable for applications requiring higher thermal margins. The housing color is blue rather than black.

Q: Are all substitute parts RoHS compliant?

A: All identified substitute parts carry either RoHS Compliant or ROHS3 Compliant status. ROHS3 Compliant parts (103648-9, 1-926657-0, 2-87175-2, 0050579210) represent the current regulatory standard. RoHS Compliant parts (103688-9, 1-925366-0, 65039-027LF, 65240-010LF) meet the original RoHS directive requirements.

Q: Do all substitute parts have the same moisture sensitivity level?

A: Yes. All parts listed, including the main part 103688-9, carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions during storage or handling.

Q: Can I mix different substitute parts in the same assembly?

A: Yes, provided all parts maintain the same electrical and mechanical specifications: 10 positions, 0.100" pitch, female socket contacts, crimp termination, and compatible operating temperature ranges. Mixing parts with different insulation materials or colors does not affect electrical compatibility but may affect visual identification or material-specific performance characteristics in the application.

Q: What is the difference between crimp termination and other termination methods?

A: Crimp termination requires a separate crimping tool and process to attach wire contacts to the housing. All listed parts use crimp termination, meaning they require compatible crimp contacts (not included with the housing) and appropriate crimping equipment for assembly.

Q: Are contacts included with these connector housings?

A: No. All parts listed carry the note "Contacts Not Included." Crimp contacts must be sourced separately and are compatible with the 0.100" (2.54mm) pitch specification.
