Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 57102-G08-18 are categorized based on the following critical parameters that determine functional compatibility:

Primary Compatibility Criteria:

• Pitch - Mating: 0.079" (2.00mm)
• Number of Positions: 36
• Number of Rows: 2
• Row Spacing - Mating: 0.079" (2.00mm)
• Connector Type: Header
• Contact Type: Male Pin
• Mounting Type: Through Hole
• Termination: Solder
• Style: Board to Board

Direct Substitutes (Same Position Count):

• 57102-G08-18LF: Identical electrical and mechanical specifications with active product status and RoHS compliance
• MTMM-118-09-G-D-157 (Samtec): Equivalent 36-position configuration with enhanced current rating and operating temperature range

Functional Alternatives (Different Position Count):

• 57102-S06-25LF: 50-position variant maintaining identical pitch and row spacing; suitable where additional contact capacity is acceptable
• MTMM-118-13-S-D-150 (Samtec): 36-position cuttable header with extended post length and operating temperature range

Parameter Comparison

Engineering Selection Recommendations

Primary Direct Substitute: 57102-G08-18LF is the recommended direct replacement for the obsolete 57102-G08-18. Both parts maintain identical electrical and mechanical specifications with 36 positions at 2.00mm pitch. The primary distinction is product status: 57102-G08-18LF is active and RoHS compliant, addressing regulatory requirements for new designs and production continuity.

Alternative Substitutes from Samtec: MTMM-118-09-G-D-157 and MTMM-118-13-S-D-150 provide equivalent 36-position configurations with enhanced specifications. Both Samtec parts feature ROHS3 compliance, extended operating temperature range (-55°C to 125°C), and increased current rating (3A). The primary trade-off is extended post length, which may require PCB layout modification. MTMM-118-09-G-D-157 offers shorter overall contact length (0.535") compared to MTMM-118-13-S-D-150 (0.673"), providing flexibility for different board thickness applications.

Position-Variant Alternative: 57102-S06-25LF maintains compatibility with the 2.00mm pitch ecosystem but provides 50 positions instead of 36. This part is suitable only where additional contact capacity is required and PCB layout can accommodate the increased connector footprint.

Frequently Asked Questions (FAQ)

Q: Can 57102-G08-18LF be used as a direct replacement for 57102-G08-18? A: Yes. Both parts share identical pitch (0.079" / 2.00mm), position count (36), row configuration (2 rows), contact type (male pin), and electrical ratings (2A at 200V AC/DC). The primary difference is product status and RoHS compliance.

Q: What is the key difference between Amphenol ICC and Samtec substitutes? A: Amphenol ICC 57102-G08-18LF maintains the original form factor with 0.118" (3.00mm) post length. Samtec MTMM series parts feature extended post lengths (0.319" to 0.464"), phosphor bronze contact material, LCP insulation, and enhanced operating temperature range. Post length differences require PCB design verification.

Q: Is 57102-S06-25LF compatible with designs using 57102-G08-18? A: Partial compatibility exists. The 50-position variant maintains identical pitch and row spacing but requires PCB layout modification to accommodate the additional 14 contact positions. Electrical ratings remain equivalent at 2A/200V.

Q: What compliance certifications apply to substitute parts? A: 57102-G08-18LF is RoHS compliant. MTMM-118-09-G-D-157 and MTMM-118-13-S-D-150 are ROHS3 compliant. All parts carry UL94 V-0 material flammability rating and EAR99 export classification.

Q: Are there packaging differences between substitute parts? A: 57102-G08-18LF and 57102-S06-25LF are supplied in box packaging. Samtec MTMM parts do not specify packaging format in available data. Verify packaging requirements with supplier for production planning.

Q: Can Samtec MTMM parts be used in existing PCB designs without modification? A: Extended post length in Samtec parts (0.319" to 0.464" versus 0.118" in Amphenol) may require PCB thickness verification and solder joint design review. Contact length mating specifications remain compatible at 0.157" (4.00mm) for MTMM-118-09-G-D-157, with minor variation (0.150" / 3.81mm) for MTMM-118-13-S-D-150.
