Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the Molex 0877584017 are qualified based on strict electrical and mechanical parameter alignment. The following critical parameters determine substitution eligibility:

Core Compatibility Parameters:

• Number of Positions: 40
• Number of Rows: 2
• Pitch - Mating: 0.079" (2.00mm)
• Row Spacing - Mating: 0.079" (2.00mm)
• Connector Type: Header
• Contact Type: Male Pin
• Mounting Type: Through Hole
• Termination: Solder
• Fastening Type: Push-Pull
• Shrouding: Unshrouded
• Contact Finish - Mating: Gold
• Contact Finish - Post: Tin
• Insulation Color: Black
• Material Flammability Rating: UL94 V-0

All four substitute parts meet these core parameters. Variations in contact length, insulation material composition, contact finish thickness, and operating temperature specifications do not prevent functional substitution in applications where the main part is specified, provided the substitute part's electrical and mechanical characteristics remain within acceptable tolerances for the intended circuit design.

Parameter Comparison

Engineering Selection Recommendations

All four substitute parts are active products with confirmed RoHS compliance status. Selection between the Molex 0877584017 and its substitutes should be based on the following compliance and certification factors:

Molex 0877584017: ROHS3 Compliant, REACH Unaffected. Suitable for applications requiring ROHS3 certification and where REACH compliance is not a regulatory requirement.

Amphenol ICC 10075024-G01-20ULF and 57102-G06-20LF: RoHS Compliant, REACH Affected. These parts are suitable for applications where REACH compliance is mandatory. The 10075024-G01-20ULF is packaged in Tube format, while the 57102-G06-20LF is packaged in Bulk format.

Samtec TMM-120-03-L-D and TMM-120-03-S-D: ROHS3 Compliant, REACH Unaffected. These parts match the Molex compliance profile and are suitable for applications with identical regulatory requirements. Both are packaged in Bulk format. The TMM-120-03-S-D features contact finish thickness of 30.0µin (0.76µm) on mating surfaces, matching the Molex specification, while the TMM-120-03-L-D features 10.0µin (0.25µm) thickness.

Packaging format selection (Tray, Tube, or Bulk) should be determined by procurement and assembly process requirements.

Frequently Asked Questions (FAQ)

Q: Can I substitute the Molex 0877584017 with any of these four parts without PCB redesign?

A: Yes. All substitute parts share identical pitch (0.079" / 2.00mm), row spacing (0.079" / 2.00mm), number of positions (40), number of rows (2), mounting type (Through Hole), and contact configuration (Male Pin, Push-Pull, Unshrouded). PCB footprints designed for the Molex 0877584017 are mechanically compatible with all listed substitutes. Minor variations in overall contact length (ranging from 0.295" to 0.323") do not affect PCB hole placement or electrical function.

Q: What is the difference between the two Amphenol ICC parts?

A: Both Amphenol ICC parts (10075024-G01-20ULF and 57102-G06-20LF) are from the Minitek® 2.00mm series and share identical electrical and mechanical specifications. The primary differences are packaging format (Tube versus Bulk) and contact length post specification (0.079" versus 0.098"). Selection between these two should be based on procurement packaging requirements and assembly process compatibility.

Q: What is the difference between the two Samtec TMM parts?

A: Both Samtec parts (TMM-120-03-L-D and TMM-120-03-S-D) are from the TMM series and share identical mechanical specifications and operating temperature range (-55°C ~ 125°C). The primary difference is contact finish thickness on mating surfaces: TMM-120-03-L-D features 10.0µin (0.25µm) while TMM-120-03-S-D features 30.0µin (0.76µm), matching the Molex specification.

Q: Are there compliance differences between substitutes?

A: Yes. The Molex 0877584017 and Samtec parts (TMM-120-03-L-D and TMM-120-03-S-D) are ROHS3 Compliant and REACH Unaffected. The Amphenol ICC parts (10075024-G01-20ULF and 57102-G06-20LF) are RoHS Compliant and REACH Affected. Select based on your application's regulatory requirements.

Q: Do all parts have the same current and voltage ratings?

A: The Molex 0877584017 does not specify current or voltage ratings in the provided data. Amphenol ICC parts are rated for 2A (AC/DC) and 200V (AC/DC). Samtec parts are rated for 3.2A per Contact. Verify that the selected substitute meets your circuit's electrical requirements.

Q: What packaging options are available?

A: Molex 0877584017 is supplied in Tray format. Amphenol ICC 10075024-G01-20ULF is supplied in Tube format. Amphenol ICC 57102-G06-20LF, Samtec TMM-120-03-L-D, and Samtec TMM-120-03-S-D are supplied in Bulk format. Confirm packaging compatibility with your procurement and assembly processes.
