IPS1-120-01-H-D Equivalent & Substitute Parts

Part Overview

The IPS1-120-01-H-D is a 40-position receptacle connector from Samtec Inc.'s Mini Mate® IPS1 series, designed for board-to-board applications with 0.100" (2.54mm) pitch spacing. This through-hole mounted connector features gold-plated mating contacts and is rated for 775VAC and 1095VDC operation across an extended temperature range of -55°C to 125°C. The part maintains Active product status and ROHS3 compliance. Equivalent and substitute parts within this series provide alternative contact finish specifications while maintaining core electrical and mechanical compatibility.

Substitute Part Grouping Explanation

Substitute parts for the IPS1-120-01-H-D are identified within the Mini Mate® IPS1 series based on identical core electrical and mechanical parameters. The substitution criteria are strictly limited to the following parameters that remain constant across all listed parts:

• Connector type (Receptacle)
• Number of positions (40)
• Pitch spacing (0.100" / 2.54mm)
• Number of rows (2)
• Row spacing (0.100" / 2.54mm)
• Mounting type (Through Hole)
• Termination method (Solder)
• Fastening type (Push-Pull)
• Mating contact finish (Gold)
• Insulation material (Liquid Crystal Polymer)
• Operating temperature range (-55°C ~ 125°C)
• Voltage rating (775VAC, 1095VDC)
• Product status (Active)
• Compliance certifications (ROHS3, MSL 1)

The identified substitutes differ only in contact finish thickness specifications on the mating side and post-side finish material, which do not affect core connector functionality or board-level compatibility.

Parameter Comparison

Engineering Selection Recommendations

All three parts—IPS1-120-01-H-D, IPS1-120-01-L-D, and IPS1-120-01-S-D—maintain Active product status and full ROHS3 compliance. Selection between these parts should be based on inventory availability and specific contact finish thickness requirements for your application. The IPS1-120-01-S-D offers the highest mating contact finish thickness at 30.0µin (0.76µm), while the IPS1-120-01-L-D provides 10.0µin (0.25µm). All parts are electrically and mechanically interchangeable for standard board-to-board 40-position 0.100" pitch applications.

Frequently Asked Questions (FAQ)

Q: Are these parts electrically interchangeable? A: Yes. All three parts share identical electrical ratings (775VAC, 1095VDC), operating temperature range (-55°C to 125°C), and contact material specifications. They are suitable for the same circuit applications.

Q: What is the difference between the substitute parts? A: The primary differences are contact finish thickness on the mating side and post-side finish material. IPS1-120-01-S-D has 30.0µin gold plating, IPS1-120-01-L-D has 10.0µin gold plating, while IPS1-120-01-H-D does not specify finish thickness. All use tin post-side finish except IPS1-120-01-H-D.

Q: Are these parts mechanically compatible? A: Yes. All parts share identical mechanical specifications: 40 positions, 0.100" pitch, 2-row configuration, through-hole mounting, and push-pull fastening. They mount identically on PCBs.

Q: Do all parts meet the same compliance standards? A: Yes. All three parts are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating and carry the same ECCN and HTSUS classifications.

Q: Can I substitute these parts on existing designs? A: Yes, within the Mini Mate® IPS1 series. The identical pitch, position count, mounting type, and electrical ratings ensure direct substitution on PCBs designed for the IPS1-120 base product number.
