Row Spacing - Mating: 0.100" (2.54mm)
Connector Type: Header
Contact Type: Male Pin
Mounting Type: Through Hole
Termination: Solder
Fastening Type: Push-Pull
Material Flammability Rating: UL94 V-0

Secondary Compatibility Parameters:

Contact Shape: Square (preferred) or Circular (acceptable with dimensional verification)
Contact Finish - Mating: Gold or equivalent noble metal plating
Operating Temperature Range: Minimum -55°C ~ 125°C
Current Rating: Minimum 3A per contact
Insulation Color: Black

Substitute parts are grouped into two categories:

Category 1: Direct Amphenol ICC BERGSTIK® II Series Equivalents These parts maintain identical mechanical and electrical specifications with the main part, differing only in product status (active vs. obsolete) or RoHS compliance designation.

Category 2: Cross-Manufacturer Equivalents These parts from TE Connectivity, Preci-Dip, and Samtec maintain the critical dimensional and electrical parameters but may exhibit variations in contact geometry (circular vs. square), contact finish specifications, or insulation material composition. These variations remain within acceptable substitution parameters for standard board-to-board interconnection applications.

Engineering Selection Recommendations

Tier 1: Direct Amphenol ICC Equivalents (Recommended for Existing Designs)

The parts 67997-172HLF and 67997-672H are direct mechanical and electrical equivalents of the 67997-672. Both maintain identical connector geometry, contact configuration, and electrical performance specifications. The 67997-172HLF is the preferred selection for new designs requiring RoHS compliance, as it carries active product status and RoHS Compliant designation. The 67997-672H remains active but retains RoHS non-compliant status, matching the original part's regulatory classification.

Tier 2: Cross-Manufacturer Equivalents with Active Status

The Samtec MTLW series (MTLW-136-07-F-D-230, MTLW-136-07-H-D-230, MTLW-136-07-L-D-230) and TD-136-G-A provide active product status with ROHS3 compliance. These parts maintain the critical 72-position, 2-row, 0.100" pitch configuration and square contact geometry. The MTLW series offers enhanced current rating (5.2A per contact versus 3A), providing design margin for higher-current applications. All three MTLW variants are suitable for board-to-board or cable applications.

Tier 3: Alternative Geometry Substitutes

The Preci-Dip 450 series (450-10-272-00-013101, 450-80-272-00-001101, 450-V3-272-00-006101) and TE Connectivity 4-103240-0-36 employ circular contact geometry rather than square contacts. These parts maintain all critical dimensional parameters (72 positions, 2 rows, 0.100" pitch) and are suitable for applications where contact geometry variation is acceptable. The Preci-Dip parts carry ROHS3 compliance and active status. The TE Connectivity part is discontinued at DiGi Electronics and should be considered only for legacy system support.

Compliance Considerations:

For applications requiring RoHS compliance, select from: 67997-172HLF, 450-10-272-00-013101, 450-80-272-00-001101, 450-V3-272-00-006101, MTLW-136-07-F-D-230, MTLW-136-07-H-D-230, MTLW-136-07-L-D-230, or TD-136-G-A.

For applications with legacy RoHS non-compliant requirements, 67997-672H and 4-103240-0-36 remain available.

Frequently Asked Questions (FAQ)

Q1: Can the 67997-172HLF directly replace the 67997-672 in existing PCB designs?

A: Yes. The 67997-172HLF is a direct mechanical and electrical equivalent. Both parts share identical connector geometry, 72-position configuration, 0.100" pitch spacing, square contact shape, and solder termination. The primary difference is product status (active versus obsolete) and RoHS compliance designation. No PCB layout modifications are required.

Q2: What is the significance of the contact shape difference between square and circular contacts?

A: Contact shape affects mating force, contact resistance, and mechanical durability. Square contacts (67997-672, 67997-172HLF, MTLW series, TD-136-G-A) provide consistent contact pressure across the mating surface. Circular contacts (Preci-Dip 450 series, TE Connectivity 4-103240-0-36) concentrate contact force at discrete points. For standard board-to-board applications, both geometries are functionally equivalent. Applications requiring specific contact force characteristics should maintain contact shape consistency.

Q3: Why do some substitute parts specify higher current ratings (5.2A) compared to the original 3A specification?

A: The Samtec MTLW series is designed with enhanced contact geometry and material composition that supports higher current density. The 5.2A rating reflects the contact's thermal and mechanical capability. For applications requiring only 3A, the MTLW series provides design margin and improved reliability. The higher rating does not affect compatibility with 3A-rated applications.

Q4: Are the Preci-Dip 450 series parts with different contact finishes (gold, tin, mixed) interchangeable?

A: The three Preci-Dip variants (450-10-272-00-013101 with gold finish, 450-80-272-00-001101 with tin finish, 450-V3-272-00-006101 with mixed gold/tin finish) are mechanically interchangeable. Contact finish selection depends on application requirements: gold finishes provide superior corrosion resistance and lower contact resistance; tin finishes offer cost optimization for non-critical applications. Mating connector contact finish should be considered when selecting among these variants.

Q5: What is the difference between the three Samtec MTLW variants (F-D, H-D, L-D)?

A: The three MTLW variants differ in contact finish specifications. MTLW-136-07-F-D-230 features gold mating finish (3.00µin) with tin post finish. MTLW-136-07-H-D-230 features gold mating finish (30.0µin) with gold post finish (3.00µin). MTLW-136-07-L-D-230 features gold mating finish (10.0µin) with tin post finish. All three maintain identical mechanical configuration and current rating. Selection depends on contact finish durability and corrosion resistance requirements for the specific application environment.

Q6: Is the TE Connectivity 4-103240-0-36 suitable for new designs?

A: The TE Connectivity 4-103240-0-36 is discontinued at DiGi Electronics and carries RoHS non-compliant status. This part should be reserved for legacy system support and repair applications only. For new designs, select from the active product alternatives listed in Tier 1 or Tier 2 recommendations.

Q7: What packaging options are available for these substitute parts?

A: Packaging varies by manufacturer and part number. Amphenol ICC parts are supplied in Bulk packaging. Samtec MTLW series and TD-136-G-A are supplied in Bulk packaging. Preci-Dip 450 series are supplied in Bulk packaging. TE Connectivity 4-103240-0-36 packaging is not specified. Verify packaging requirements with component procurement specifications before finalizing part selection.

Q8: Do all substitute parts meet UL94 V-0 flammability requirements?

A: Yes. All listed substitute parts carry UL94 V-0 material flammability rating, matching the original 67997-672 specification. This rating is maintained across all manufacturers and variants listed in this reference.

Q9: What is the Moisture Sensitivity Level (MSL) for these connectors?

A: All listed parts carry MSL 1 (Unlimited) designation, indicating no moisture sensitivity restrictions. These connectors do not require special moisture control during storage, handling, or assembly.

Q10: Are there any REACH or ECCN compliance differences among the substitute parts?

A: All listed parts carry ECCN EAR99 classification. REACH status varies: Amphenol ICC parts are REACH Affected; Preci-Dip parts are REACH Unaffected; Samtec and TE Connectivity REACH status is not specified in the provided data. Verify REACH compliance requirements with your regulatory or procurement department for applications subject to REACH regulations.
