Key Parameters

Substitute Part Grouping Explanation

The TMM-103-02-LM-S and its identified substitute TMM-103-02-L-S are functionally equivalent based on the following critical parameters:

• Connector Type & Configuration: Both are 3-position male pin headers with identical pitch (2.00mm)
• Electrical Characteristics: Identical current rating (3.2A per Contact), contact material (Phosphor Bronze), and mating contact finish (Gold)
• Mechanical Specifications: Matching contact dimensions, insulation height, overall contact length, and through-hole mounting configuration
• Material & Compliance: Both utilize Liquid Crystal Polymer insulation, maintain ROHS3 compliance, and share identical operating temperature range (-55°C ~ 125°C)
• Moisture Sensitivity: Both rated MSL 1 (Unlimited)

The substitution is based strictly on these electrical and mechanical parameters being identical across both part numbers within the TMM series.

Parameter Comparison

Engineering Selection Recommendations

Both TMM-103-02-LM-S and TMM-103-02-L-S are active production parts with identical electrical and mechanical specifications. Selection between these part numbers should be based on inventory availability and supply chain requirements. Both parts maintain ROHS3 compliance and carry identical regulatory classifications (ECCN: EAR99, HTSUS: 8536.69.4040). The TMM-103-02-L-S currently maintains higher inventory levels (4216 Pcs) compared to TMM-103-02-LM-S (1030 Pcs), which may influence procurement decisions for high-volume applications.
