Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 91812-110 are qualified based on the following critical parameters that determine functional compatibility:

Core Matching Parameters:

• Number of Positions: 10
• Pitch - Mating: 0.079" (2.00mm)
• Number of Rows: 2
• Row Spacing - Mating: 0.079" (2.00mm)
• Mounting Type: Surface Mount
• Termination: Solder
• Fastening Type: Push-Pull
• Contact Type: Female Socket
• Connector Type: Receptacle

Acceptable Variations:

• Contact Finish - Mating: Gold (thickness may vary: 10.0µin to 30.0µin)
• Insulation Height: 0.110" to 0.177" (2.79mm to 4.50mm)
• Contact Material: Beryllium Copper or Phosphor Bronze
• Insulation Material: Plastic, Thermoplastic, or Liquid Crystal Polymer (LCP)
• Product Status: Active substitutes preferred over obsolete
• RoHS Compliance: Active substitutes are RoHS3 compliant

Substitutes are grouped into two categories: direct manufacturer alternatives (Amphenol ICC 91812-110LF) and cross-manufacturer equivalents (Molex Milli-Grid series, Samtec Tiger Eye™ SMM and TLE series).

Parameter Comparison

Engineering Selection Recommendations

Direct Amphenol ICC Substitute: The 91812-110LF is the primary direct substitute, offering identical electrical and mechanical specifications with the advantage of active product status and RoHS compliance. This part maintains the same Minitek® series design, 0.157" insulation height, and beryllium copper contact material. The transition from tin-lead to gold post finish on the 91812-110LF provides improved corrosion resistance.

Molex Milli-Grid Series (0872631003, 0872631095, 0873811018): These Molex alternatives provide functional equivalence with extended operating temperature range (-55°C to 105°C) and specified current/voltage ratings. The 0872631003 and 0872631095 feature bottom entry configuration with 0.110" insulation height, while 0873811018 maintains the 0.157" height matching the original design. All three are ROHS3 compliant and actively supported.

Samtec Tiger Eye™ SMM Series (SMM-105-02-L-D, SMM-105-02-S-D-P-TR): These connectors offer enhanced electrical performance with 3.2A per contact current rating and 350VAC voltage rating. The SMM series uses Liquid Crystal Polymer (LCP) insulation with UL94 V-0 flammability rating. Insulation height of 0.140" represents a minor reduction from the original 0.157". Available in tube and tape & reel packaging.

Samtec TLE Series (TLE-105-01-G-DV-A-K, TLE-105-01-G-DV-A-K-TR, TLE-105-01-G-DV-A-P-TR, TLE-105-01-G-DV-K-TR): The TLE pass-through receptacle connectors provide the highest current rating (3.2A per contact) and extended temperature range (-55°C to 125°C). These parts feature phosphor bronze contacts with gold mating finish and LCP insulation. Insulation height of 0.177" exceeds the original specification. Available in tube and tape & reel configurations with pick-and-place features.

All substitute parts maintain the critical 0.079" (2.00mm) pitch and 2-row configuration required for mechanical and electrical compatibility with mating connectors designed for the 91812-110.

Frequently Asked Questions (FAQ)

Q: Can I use the 91812-110LF as a direct replacement for the 91812-110? A: Yes. The 91812-110LF is functionally equivalent with identical pitch, position count, row configuration, and mounting type. The primary differences are active product status, RoHS compliance, and gold post finish instead of tin-lead. This is the recommended direct substitute.

Q: What are the key differences between Amphenol ICC and Molex alternatives? A: Molex Milli-Grid connectors (0872631003, 0872631095, 0873811018) provide specified operating temperature ranges and current/voltage ratings not available for the original 91812-110. The 0872631003 and 0872631095 feature bottom entry configuration with reduced insulation height (0.110"), while 0873811018 maintains 0.157" height. All are ROHS3 compliant.

Q: How do Samtec connectors compare to the original part? A: Samtec Tiger Eye™ SMM and TLE series offer superior electrical performance with 3.2A per contact current rating and extended temperature range to 125°C. The TLE series provides pass-through capability with higher insulation height (0.177"). Both series use LCP insulation with UL94 V-0 rating. These are premium alternatives for demanding applications.

Q: Are there packaging considerations when selecting a substitute? A: Yes. The original 91812-110 is supplied in bulk packaging. Substitutes are available in tube, tape & reel, or bulk configurations. Tape & reel packaging (SMM-105-02-S-D-P-TR, TLE variants with -TR suffix) is preferred for automated assembly. Tube packaging is suitable for manual assembly or lower-volume production.

Q: What is the significance of the insulation height variation across substitutes? A: Insulation height affects board-to-board spacing and mating connector clearance. The original 91812-110 specifies 0.157" (4.00mm). Molex alternatives at 0.110" (2.79mm) reduce stack height, while Samtec TLE at 0.177" (4.50mm) increases it. Verify mating connector compatibility and PCB layout constraints before selection.

Q: Do all substitutes meet RoHS requirements? A: The original 91812-110 is RoHS non-compliant. All listed substitutes are RoHS3 compliant, making them suitable for applications requiring RoHS certification. The 91812-110LF specifically transitions from the non-compliant original to full RoHS compliance.

Q: What contact material differences exist among substitutes? A: The original 91812-110 and 91812-110LF use beryllium copper contacts. Molex Milli-Grid series do not specify contact material. Samtec Tiger Eye™ SMM and TLE series use beryllium copper and phosphor bronze respectively. All maintain gold mating finish with varying thickness (10.0µin to 30.0µin).
