Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 74817-1001 is determined by the following critical parameters:

Primary Compatibility Criteria:

• Number of Positions: 36 (exact match required)
• Pitch: 0.079" (2.00mm) (exact match required)
• Number of Rows: 5 (exact match required)
• Connector Type: Header, Male Pins (exact match required)
• Mounting Type: Through Hole (exact match required)
• Termination: Press-Fit (exact match required)

Secondary Compatibility Criteria:

• Contact Layout: 30 Signal, 6 Ground (exact match required)
• Features: Shielded (exact match required)
• Material Flammability Rating: UL94 V-0 (minimum requirement)
• Operating Temperature Range: Must encompass -55°C to 105°C
• Current Rating: Minimum 1A

Acceptable Variations:

• Contact Finish Thickness: Minor variations within manufacturing tolerance
• RoHS Compliance Status: May differ from original
• Manufacturer: Different manufacturer acceptable if all electrical and mechanical parameters match

The 74817-1001LF qualifies as a direct substitute meeting all primary and secondary criteria. The MP2-H030-51P1-S-KR does not qualify as a substitute due to position count mismatch (30 vs. 36 positions).

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Pin-Compatible Substitution):

The 74817-1001LF is the appropriate selection for direct replacement of the obsolete 74817-1001. Both parts share identical electrical and mechanical specifications including 36-position count, 2.00mm pitch, 5-row configuration, press-fit termination, and shielded construction. The 74817-1001LF maintains active product status with RoHS compliance, providing improved regulatory alignment while preserving full functional compatibility. Contact finish thickness variation (30.0µin vs. 31.5µin) falls within acceptable manufacturing tolerances and does not affect electrical performance or reliability.

For New Design Consideration:

The MP2-H030-51P1-S-KR from 3M is not suitable as a substitute for the 74817-1001 due to position count mismatch (30 vs. 36 positions). This part cannot be used in applications requiring the full 36-position configuration and should not be considered for replacement scenarios.

Frequently Asked Questions (FAQ)

Q: Can the 74817-1001LF be used as a direct replacement for the 74817-1001?

A: Yes. The 74817-1001LF meets all electrical and mechanical requirements for direct substitution. Both parts feature 36 positions, 2.00mm pitch, 5-row layout, press-fit termination, and shielded construction. The primary difference is RoHS compliance status, with the LF variant meeting current regulatory requirements.

Q: What is the significance of the "LF" suffix in the 74817-1001LF part number?

A: The "LF" designation indicates lead-free construction and RoHS compliance. This variant maintains identical form, fit, and function to the original 74817-1001 while meeting environmental and regulatory standards.

Q: Why is the MP2-H030-51P1-S-KR not a suitable substitute?

A: The MP2-H030-51P1-S-KR has 30 positions compared to the 36 positions of the 74817-1001. This fundamental difference in position count makes it incompatible with PCB layouts and mating connectors designed for the 36-position configuration.

Q: Are there packaging differences between the main part and substitute?

A: The 74817-1001 packaging is not specified in available documentation. The 74817-1001LF is supplied in tube packaging. Verify packaging requirements for your procurement and assembly processes.

Q: What is the operating temperature difference between the 74817-1001 and 74817-1001LF?

A: Both parts operate across the identical temperature range of -55°C to 105°C. Temperature performance is equivalent for both variants.

Q: Does the contact finish thickness difference affect performance?

A: The contact finish thickness variation (31.5µin for 74817-1001 vs. 30.0µin for 74817-1001LF) represents a minor difference within acceptable manufacturing tolerances. Both finishes provide equivalent electrical conductivity and contact reliability for the specified 1A current rating.
