Key Parameters

Substitute Part Grouping Explanation

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

• Pitch and Position Count: All substitutes maintain 0.079" (2.00mm) mating pitch with 10 positions in 2 rows
• Connector Type and Contact Configuration: All substitutes are male pin headers with push-pull fastening
• Mounting and Termination: All substitutes use through-hole mounting with solder termination
• Electrical and Mechanical Compatibility: Contact material, finish type, and overall dimensions must support equivalent board-to-board or cable connectivity
• Compliance and Environmental Rating: All substitutes maintain UL94 V-0 flammability rating and MSL 1 classification

Substitutes are grouped into two functional categories:

Category A - Direct Header Replacements (57102-F08-05LF, 57102-F08-05ULF, 57102-G06-05LF, M22-2580546, TMM-105-03-G-D): These parts maintain standard header form factor with mating contact lengths between 0.157" (4.00mm) and 0.197" (5.00mm), suitable for direct mechanical and electrical interchange.

Category B - Stacking Header Variants (TW-05-02-G-D-150-140, TW-05-03-L-D-175-235, TW-05-09-G-D-190-135, TW-05-11-S-D-185-090): These parts feature integrated spacer heights and extended tail lengths for board-to-board stacking applications, with mating post lengths between 0.087" (2.210mm) and 0.131" (3.327mm).

Parameter Comparison

Engineering Selection Recommendations

For Direct Header Replacement (Category A)

The Amphenol ICC (FCI) Minitek® 2.00mm series (57102-F08-05LF, 57102-F08-05ULF, 57102-G06-05LF) provides electrical and mechanical compatibility with the Molex 0877581007. All three variants maintain identical mating contact length (0.157" / 4.00mm), gold-plated mating surfaces, and UL94 V-0 flammability certification. Packaging differences (Bulk vs. Tube) do not affect functional performance. The 57102-G06-05LF variant features GXT™ enhanced gold plating with increased thickness (30.0µin vs. standard flash), suitable for applications requiring enhanced contact durability.

The Harwin M22-2580546 offers substitution with extended mating contact length (0.197" / 5.00mm) and tin-plated mating surface. This part maintains ROHS3 compliance and UL94 V-0 rating but introduces contact material variation (Phosphor Bronze vs. Copper Alloy) and different insulation material (Polyamide PA6T). Selection requires verification that extended mating contact length and tin plating are compatible with mating receptacle design.

The Samtec TMM-105-03-G-D provides direct substitution with gold-plated mating surface and Liquid Crystal Polymer (LCP) insulation. Contact length (0.157" / 4.00mm) matches the Molex part. Phosphor Bronze contact material and LCP insulation offer enhanced thermal and mechanical performance compared to standard nylon-based designs.

For Stacking Applications (Category B)

The Samtec TW series (TW-05-02-G-D-150-140, TW-05-03-L-D-175-235, TW-05-09-G-D-190-135, TW-05-11-S-D-185-090) are board-to-board stacking headers with integrated spacer heights. These parts are not direct replacements for the Molex 0877581007 but serve specialized applications requiring controlled board separation. Selection among TW variants depends on required stack height and tail length specifications. All TW parts maintain ROHS3 compliance and gold-plated mating surfaces.

Compliance Basis

All substitute parts maintain ROHS3 or RoHS compliance and UL94 V-0 flammability certification, ensuring regulatory alignment with the original Molex part. MSL 1 (Unlimited) moisture sensitivity classification is consistent across all options.

Frequently Asked Questions (FAQ)

Q: Can the Amphenol ICC 57102 series directly replace the Molex 0877581007?

A: Yes. The 57102-F08-05LF, 57102-F08-05ULF, and 57102-G06-05LF maintain identical mating pitch (0.079" / 2.00mm), position count (10), row configuration (2), and mating contact length (0.157" / 4.00mm). Electrical and mechanical compatibility is established. Packaging format (Bulk vs. Tube) does not affect functional performance.

Q: What is the difference between 57102-F08-05LF and 57102-G06-05LF?

A: Both parts share identical electrical and mechanical specifications. The primary difference is contact finish thickness on the mating surface: 57102-F08-05LF uses flash gold plating, while 57102-G06-05LF features GXT™ enhanced gold plating at 30.0µin thickness. Enhanced plating provides increased contact durability in high-cycle mating applications.

Q: Why does the Harwin M22-2580546 have a longer mating contact length?

A: The M22-2580546 mating contact length is 0.197" (5.00mm) compared to 0.157" (4.00mm) for the Molex part. This extended length accommodates deeper mating receptacle designs. Substitution requires verification that the mating receptacle can accommodate the extended contact without mechanical interference.

Q: Are the Samtec TW series parts direct replacements?

A: No. The TW series are stacking headers with integrated spacer heights and extended tail lengths. These parts are designed for board-to-board applications requiring controlled vertical separation. They are not suitable as direct replacements for standard headers but serve specialized multi-board stacking configurations.

Q: What is the difference between TW-05-02-G-D-150-140 and TW-05-09-G-D-190-135?

A: Both parts maintain identical pitch and position count but differ in stack height and tail length. TW-05-02-G-D-150-140 provides 0.150" (3.810mm) stack height with 0.140" (4.656mm) tail length. TW-05-09-G-D-190-135 provides 0.190" (4.826mm) stack height with 0.135" (3.429mm) tail length. Selection depends on required board separation distance and PCB layout constraints.

Q: Does the Samtec TMM-105-03-G-D offer performance advantages over the Molex part?

A: The TMM-105-03-G-D uses Phosphor Bronze contact material and Liquid Crystal Polymer (LCP) insulation, compared to Copper Alloy and glass-filled Nylon in the Molex part. LCP insulation provides enhanced thermal stability and mechanical strength. Phosphor Bronze offers improved spring characteristics. These material differences support applications with elevated temperature or mechanical stress requirements.

Q: Are all substitute parts RoHS compliant?

A: Yes. All substitute parts maintain either ROHS3 or RoHS compliance status, consistent with the Molex 0877581007 ROHS3 classification.

Q: What packaging options are available for the Amphenol ICC 57102 series?

A: The 57102-F08-05LF is supplied in Bulk packaging. The 57102-F08-05ULF is supplied in Tube packaging. Both variants are functionally identical; packaging selection depends on handling, storage, and assembly process requirements.
