Molex 0877602017 Rectangular Connector Header - Equivalent & Substitute Parts

Part Overview

The Molex 0877602017 is an active-status rectangular connector header designed for through-hole, right-angle board-to-board or cable applications. This 20-position, 2-row header with 2.00mm pitch serves general purpose, automotive, and telecommunications applications. Finding equivalent and substitute parts is necessary to ensure design flexibility, manage supply chain continuity, and optimize procurement across multiple manufacturers while maintaining electrical and mechanical compatibility.

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0877602017 is determined by strict alignment of the following critical parameters:

Connector Type: Header
Contact Type: Male Pin
Number of Positions: 20
Number of Rows: 2
Pitch - Mating: 0.079" (2.00mm)
Row Spacing - Mating: 0.079" (2.00mm)
Mounting Type: Through Hole, Right Angle
Termination: Solder
Fastening Type: Push-Pull
Contact Finish - Mating: Gold
Material Flammability Rating: UL94 V-0
Moisture Sensitivity Level: 1 (Unlimited)

All three substitute parts meet these core criteria. Variations in contact length, insulation height, contact material composition, and insulation material type do not prevent functional substitution in applications where the mating interface and electrical characteristics remain compatible.

Engineering Selection Recommendations

All three substitute parts are active-status products with full RoHS and REACH compliance, matching the regulatory posture of the Molex 0877602017. Selection among these equivalents should be based on:

Amphenol ICC 58102-G61-10LF (Minitek® Series): This part maintains identical mating contact length (0.157" / 4.00mm) to the Molex original, ensuring consistent mating depth. It carries RoHS compliance and offers the highest current rating specification (2A AC/DC) with defined voltage rating (200V AC/DC). Packaging is available in bulk format.

Harwin M22-2541005 (M22 Series): This part features a cuttable header design, providing design flexibility for custom position configurations. It specifies operating temperature range (-40°C to 105°C) and current rating (2A), with ROHS3 compliance. Insulation material is polyamide-based (PA6T, Nylon 6T).

Samtec TMM-110-01-F-D-RA (TMM Series): This part offers the highest current rating per contact (3.2A) and the widest operating temperature range (-55°C to 125°C). It uses liquid crystal polymer (LCP) insulation material and maintains ROHS3 compliance. Contact finish thickness on the mating surface is specified at 3.00µin (0.076µm).

All parts maintain UL94 V-0 flammability rating (except Samtec, which does not specify) and MSL 1 moisture sensitivity level, ensuring compatibility with standard PCB assembly and storage protocols.

Frequently Asked Questions (FAQ)

Q: Can the Amphenol ICC 58102-G61-10LF directly replace the Molex 0877602017 in existing designs?

A: Yes. Both parts share identical mating pitch (2.00mm), row spacing (2.00mm), number of positions (20), mounting type (through-hole right-angle), and contact finish (gold). The matching mating contact length (0.157" / 4.00mm) ensures consistent mating depth with existing receptacles.

Q: What is the primary difference between the Harwin M22-2541005 and the other substitutes?

A: The Harwin M22-2541005 features a cuttable header design, allowing custom position configurations by cutting the header to shorter lengths. This provides design flexibility not available in the fixed 20-position Molex or other substitutes. All other electrical and mechanical parameters remain compatible.

Q: Which substitute part offers the best thermal performance?

A: The Samtec TMM-110-01-F-D-RA specifies the widest operating temperature range (-55°C to 125°C) compared to the Harwin M22-2541005 (-40°C to 105°C). The Molex 0877602017 and Amphenol ICC 58102-G61-10LF do not specify operating temperature ranges in the provided data.

Q: Are all substitute parts RoHS compliant?

A: Yes. The Molex 0877602017 is ROHS3 compliant. The Amphenol ICC 58102-G61-10LF is RoHS compliant. The Harwin M22-2541005 and Samtec TMM-110-01-F-D-RA are both ROHS3 compliant. All parts are REACH unaffected.

Q: What are the packaging differences among these parts?

A: The Molex 0877602017 is supplied in tray packaging. The Amphenol ICC 58102-G61-10LF, Harwin M22-2541005, and Samtec TMM-110-01-F-D-RA are supplied in bulk packaging. Packaging format may affect procurement quantities and handling procedures.

Q: Do all substitute parts have the same contact length specifications?

A: No. Mating contact lengths vary: Molex and Amphenol both specify 0.157" (4.00mm), Harwin specifies 0.138" (4.60mm), and Samtec specifies 0.126" (3.20mm). Post contact lengths also vary across all four parts. These variations do not prevent functional substitution in standard board-to-board applications where mating receptacles accommodate the specified contact geometry.

Q: Which substitute part has the highest current rating?

A: The Samtec TMM-110-01-F-D-RA specifies 3.2A per contact, the highest among all parts. The Amphenol ICC 58102-G61-10LF and Harwin M22-2541005 both specify 2A. The Molex 0877602017 does not specify a current rating in the provided data.
