Substitute Part Grouping Explanation

Substitution eligibility for the MTMM-110-05-G-S-185 is determined by strict alignment of the following critical parameters:

• Pitch - Mating: 0.079" (2.00mm) — mechanical compatibility with mating connectors
• Number of Positions: 10 — circuit board layout and signal routing
• Number of Rows: 1 — physical footprint and mounting configuration
• Connector Type: Header, Cuttable — board-to-board or cable interface capability
• Contact Type: Male Pin — gender compatibility with female receptacles
• Mounting Type: Through Hole — PCB assembly process compatibility
• Termination: Solder — connection method to printed circuit board
• Fastening Type: Push-Pull — mechanical engagement mechanism
• Contact Finish - Mating: Gold — electrical conductivity and corrosion resistance
• Operating Temperature Range: Must encompass or match the application requirement
• Current Rating: Must meet or exceed circuit current demands
• Material Flammability Rating: UL94 V-0 — safety compliance requirement

The substitute part 26631001RP2 (NorComp Inc., Series 2663) meets all critical mechanical and electrical parameters for direct substitution in applications where the operating temperature range of -40°C ~ 105°C and current rating of 2A are acceptable.

Parameter Comparison

Engineering Selection Recommendations

The MTMM-110-05-G-S-185 is the primary component choice for applications requiring the full operating temperature range of -55°C ~ 125°C and current capacity of 3A. This part is ROHS3 compliant and maintains active production status.

The 26631001RP2 substitute part is suitable for applications where:

• Operating temperature requirements fall within -40°C ~ 105°C
• Circuit current does not exceed 2A per contact
• Polyamide (PA6T) insulation material is acceptable in place of Liquid Crystal Polymer (LCP)
• Contact length variations of 0.035" (0.89mm) in mating length and 0.050" (1.27mm) in overall length do not affect mechanical fit or electrical performance

Both parts share identical pitch, position count, row configuration, mounting type, termination method, fastening mechanism, and contact finish specifications. Both maintain UL94 V-0 flammability compliance and are available in production quantities.

Frequently Asked Questions (FAQ)

Q: Can 26631001RP2 be used as a direct drop-in replacement for MTMM-110-05-G-S-185?

A: Direct substitution is possible only if the application operates within -40°C ~ 105°C and does not exceed 2A per contact. The identical 2.00mm pitch and 10-position configuration ensure mechanical compatibility with mating connectors. However, the different insulation material (Polyamide vs. Liquid Crystal Polymer) and contact length variations must be evaluated for specific board layout and mechanical assembly requirements.

Q: What are the key differences between these two parts?

A: The primary differences are operating temperature range (-55°C ~ 125°C vs. -40°C ~ 105°C), current rating (3A vs. 2A), insulation material (LCP vs. PA6T), contact mating length (0.185" vs. 0.150"), and overall contact length (0.377" vs. 0.327"). The MTMM-110-05-G-S-185 offers extended temperature capability and higher current capacity.

Q: Are both parts compatible with the same mating connectors?

A: Yes. Both parts feature identical 0.079" (2.00mm) pitch, 10-position single-row configuration, and male pin contact type. They are compatible with standard 2.00mm pitch female receptacles.

Q: What is the significance of the different insulation materials?

A: Liquid Crystal Polymer (LCP) offers superior thermal stability and dimensional consistency at elevated temperatures. Polyamide (PA6T) provides adequate performance for standard industrial applications but may exhibit greater dimensional change under thermal cycling. Material selection depends on application thermal cycling requirements and environmental exposure.

Q: Does the contact length difference affect circuit performance?

A: Contact length differences do not affect electrical performance but may impact mechanical fit within connector housings or mating receptacles. Board layout and connector cavity depth must accommodate the shorter contact length of the 26631001RP2 substitute.

Q: Is RoHS compliance status confirmed for the substitute part?

A: RoHS compliance status is not specified in the available data for 26631001RP2. Verification with NorComp Inc. is required if RoHS3 compliance is a mandatory requirement for the application.
