TE Connectivity 103688-2 Equivalent & Substitute Parts

Part Overview

The TE Connectivity 103688-2 is a 3-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 features crimp-type female socket contacts with thermoplastic insulation. The part is currently active in production with 781 pieces in stock inventory.

Substitute parts are identified when equivalent electrical and mechanical parameters are maintained across different connector series, manufacturers, or product variants. Alternative models may be required due to supply chain considerations, series discontinuation, or design standardization across connector families.

Engineering Selection Recommendations

Primary Substitutes (Highest Compatibility)

Part 103648-2 is the primary substitute for 103688-2. Both parts share identical electrical and mechanical specifications within the AMPMODU MTE series. The 103648-2 offers superior inventory availability (16185 pieces) and ROHS3 compliance status. This part is recommended for direct replacement in new designs and production continuity.

Secondary Substitutes (TE Connectivity AMPMODU Family)

Parts 926475-3 and 926657-3 maintain equivalent core parameters with enhanced insulation material specifications (glass-filled PBT variants). Both parts carry ROHS3 compliance and support the full operating temperature range (-65°C ~ 105°C). These parts are suitable for applications requiring improved mechanical durability or thermal performance within the specified range.

Alternative Series Substitute (TE Connectivity Micro Quadlok)

Part 2177231-1 provides equivalent functionality within the Micro Quadlok series. This part features glass-filled PBT insulation material. Operating temperature specification is not provided for this part. Selection of this substitute requires verification of thermal requirements for the specific application.

Cross-Manufacturer Alternatives

Part 65039-034LF (Amphenol ICC) maintains black color and equivalent core parameters with modified polyphenylene insulation. Operating temperature range is -40°C ~ 105°C, which is narrower than the main part. This part is suitable for applications within the -40°C to 105°C range.

Part 65240-003LF (Amphenol ICC) features blue housing color and thermoplastic glass-filled insulation with extended operating temperature range (-65°C ~ 125°C). The color difference requires mechanical design consideration for connector identification and assembly procedures.

Color-Variant Substitute

Part 928205-3 (TE Connectivity) features natural housing color instead of black. Operating temperature specification is not provided. This part is suitable only when color differentiation is required and thermal specifications can be verified through alternative documentation.

Compliance Considerations

All substitute parts maintain MSL 1 (Unlimited) moisture sensitivity rating. RoHS compliance status varies between RoHS Compliant and ROHS3 Compliant designations. REACH compliance status differs across substitutes. Design specifications and regulatory requirements must be verified before final part selection.

Frequently Asked Questions (FAQ)

Q: Can part 103648-2 be used as a direct replacement for 103688-2?

A: Yes. Part 103648-2 is a direct parametric equivalent within the AMPMODU MTE series. Both parts share identical connector type, contact type, position count, pitch, mounting configuration, and operating temperature range. The primary difference is ROHS3 compliance status on the 103648-2 versus RoHS Compliant status on the 103688-2.

Q: What is the difference between the TE Connectivity AMPMODU series substitutes?

A: Parts 103648-2, 926475-3, and 926657-3 differ in insulation material composition and series designation. Part 103648-2 uses thermoplastic insulation (same as main part). Parts 926475-3 and 926657-3 use polybutylene terephthalate (PBT) variants with glass filling. All three maintain the -65°C ~ 105°C operating temperature range and support 3-position, 2.54mm pitch configurations.

Q: Can cross-manufacturer parts from Amphenol ICC be used interchangeably?

A: Cross-manufacturer substitution requires verification of mechanical compatibility and connector interface specifications. Parts 65039-034LF and 65240-003LF maintain equivalent electrical and mechanical parameters but differ in insulation material, color, and operating temperature ranges. Part 65240-003LF features blue housing instead of black, which may affect assembly procedures and connector identification.

Q: What are the operating temperature limitations for substitute parts?

A: The main part 103688-2 operates from -65°C to 105°C. Part 65039-034LF has a narrower range (-40°C ~ 105°C). Part 65240-003LF supports an extended range (-65°C ~ 125°C). Part 2177231-1 and 928205-3 do not specify operating temperature ranges in available documentation. Application thermal requirements must be matched to the selected substitute's temperature specification.

Q: Are all substitute parts RoHS compliant?

A: All listed substitute parts carry either RoHS Compliant or ROHS3 Compliant status. REACH compliance status varies: some parts are REACH Unaffected, others are REACH Affected, and some show Vendor Undefined status. Regulatory compliance requirements for the end application must be verified before final part selection.

Q: What is the significance of insulation material differences?

A: The main part uses thermoplastic insulation. Substitute parts use thermoplastic, polybutylene terephthalate (PBT), glass-filled variants, or modified polyphenylene materials. These material differences affect mechanical durability, thermal performance, and chemical resistance. Material selection depends on environmental exposure and mechanical stress requirements of the specific application.

Q: Can part 65240-003LF be used despite its blue color?

A: Part 65240-003LF is electrically and mechanically equivalent but features blue housing instead of black. Color differences may affect connector identification, assembly procedures, and visual inspection protocols. Use of this part requires design review to confirm that color differentiation does not conflict with system requirements or assembly standards.

Q: What inventory considerations apply to substitute selection?

A: Inventory availability varies significantly across substitutes. Part 103648-2 has the highest availability (16185 pieces), while parts 928205-3 (1108 pieces) and 65240-003LF (1536 pieces) have lower stock levels. Supply chain planning should account for these inventory differences when selecting substitutes for production continuity.

Q: Are contacts included with these connector housings?

A: No. All listed parts, including the main part 103688-2 and all substitutes, are connector housings only. Contacts are not included and must be sourced separately. Contact specifications must be verified to ensure compatibility with the selected housing part number.
