Key Parameters

Substitute Part Grouping Explanation

Substitution for the 79258-472 is determined by strict equivalence across the following critical parameters:

• Number of positions: 72
• Number of rows: 2
• Pitch - mating: 0.100" (2.54mm)
• Row spacing - mating: 0.100" (2.54mm)
• Connector type: Header
• Contact type: Male pin
• Mounting type: Through hole, right angle
• Termination: Solder
• Fastening type: Push-Pull
• Style: Board to board
• Shrouding: Unshrouded
• Material flammability rating: UL94 V-0

Substitute parts must maintain these core electrical and mechanical specifications. Variations in contact length, insulation height, contact finish, and post length are acceptable provided they do not compromise mating compatibility or electrical performance within the application's design envelope.

Parameter Comparison

Engineering Selection Recommendations

Amphenol ICC 68459-472HLF is the primary substitute for the obsolete 79258-472. Both components are from the same manufacturer and BERGSTIK® II series, ensuring mechanical and electrical compatibility. The 68459-472HLF maintains identical mating pitch, row spacing, contact length for mating, and insulation height. The primary distinction is that 68459-472HLF is active in production with RoHS compliance, whereas the original part is obsolete and RoHS non-compliant. Contact post length differs by 0.030" (0.76mm), which is acceptable for standard PCB through-hole applications. This part is recommended for new designs and production continuity.

3M 2372-5221-TG serves as an alternative substitute from a different manufacturer. This part maintains all critical mating parameters and offers an extended operating temperature range of -55°C to 105°C. The gold contact finish on mating surfaces provides enhanced corrosion resistance compared to tin finishes. However, the insulation height is 0.052" (1.31mm) greater than the original part, and contact post length is 0.010" (0.25mm) shorter. These dimensional differences require PCB layout verification to ensure clearance and solder joint integrity. This part is suitable for applications requiring superior environmental performance.

TE Connectivity 4-103324-0-36 is a secondary alternative with breakaway header capability. This part is discontinued at DiGi Electronics, limiting long-term availability. It maintains mating compatibility with identical pitch and row spacing but features tin-lead contact finish and an extended operating temperature range of -65°C to 105°C. The insulation height is 0.048" (1.22mm) greater than the original part. Selection of this part should account for discontinuation status and availability constraints.

For new designs, Amphenol ICC 68459-472HLF is the recommended primary substitute. For applications requiring enhanced environmental performance or extended temperature operation, 3M 2372-5221-TG is a viable alternative subject to PCB layout verification.

Frequently Asked Questions (FAQ)

Q: Can the 68459-472HLF directly replace the 79258-472 without PCB modifications?

A: Yes. Both parts maintain identical mating pitch (0.100"), row spacing (0.100"), contact length for mating (0.318"), and insulation height (0.190"). The difference in contact post length (0.030") is within acceptable tolerance for standard through-hole solder joint formation. No PCB layout changes are required.

Q: What is the significance of RoHS compliance in the 68459-472HLF?

A: The 68459-472HLF is RoHS compliant, meaning it does not contain restricted substances such as lead, cadmium, or hexavalent chromium. The original 79258-472 is RoHS non-compliant. For applications subject to RoHS regulations or customer requirements, the 68459-472HLF is the appropriate selection.

Q: Why does the 3M 2372-5221-TG have a larger insulation height?

A: The 3M 2300 series uses a different insulation material (thermoplastic, glass-filled) compared to the BERGSTIK® II series. This results in a 0.052" (1.31mm) increase in insulation height. PCB layout must accommodate this dimensional difference to prevent clearance violations or component interference.

Q: Are there differences in current or voltage ratings between these parts?

A: The original 79258-472 does not specify current or voltage ratings. The 68459-472HLF is rated for 5A at 110V. The 3M 2372-5221-TG and TE 4-103324-0-36 are each rated for 3A. Application requirements must be evaluated against these ratings to ensure adequate electrical capacity.

Q: What is the difference between tin and gold contact finishes?

A: Tin contact finish provides standard electrical conductivity and is suitable for general applications. Gold contact finish (3M 2372-5221-TG) offers superior corrosion resistance and is preferred for applications exposed to moisture, salt spray, or extended storage periods. Gold finish increases component cost and is typically specified for harsh environmental conditions.

Q: Is the TE Connectivity 4-103324-0-36 still available for purchase?

A: This part is discontinued at DiGi Electronics, indicating limited availability through major distributors. Inventory may exist through secondary sources, but long-term supply cannot be assured. For new production, this part is not recommended due to discontinuation status.

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

A: The 68459-472HLF is supplied in bag packaging. The 3M 2372-5221-TG and TE 4-103324-0-36 packaging specifications are not provided in the available data. Contact manufacturers or distributors for specific packaging requirements and bulk order options.
