Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 84817-501021 is determined by the following critical parameters:

Primary Matching Criteria:

• Connector type: Header, Male Pins
• Pitch: 0.079" (2.00mm)
• Mounting type: Through Hole
• Termination method: Press-Fit
• Material flammability rating: UL94 V-0
• Moisture sensitivity level: 1 (Unlimited)

Secondary Compatibility Factors:

• Number of positions and contact layout configuration
• Operating temperature range capability
• Contact finish and finish thickness specifications
• Current rating requirements
• Shielding features

The substitute parts identified maintain compatibility with the primary electrical and mechanical interface requirements of the original component. Substitutes are grouped based on their alignment with these defined parameters.

Engineering Selection Recommendations

84817-501021LLF (Direct Amphenol ICC Substitute)

This part maintains identical electrical and mechanical specifications to the original 84817-501021, including 36 positions, 2.00mm pitch, 5-row configuration, and press-fit termination. The primary distinction is product status: 84817-501021LLF is active and RoHS compliant, whereas the original is obsolete and RoHS non-compliant. This substitute is the preferred choice for applications requiring direct form-fit-function replacement with modern compliance certifications.

MP2-H030-51P1-S-KR (3M MetPak™ MP2 Alternative)

This 3M connector differs in position count (30 versus 36) and manufacturer series. It maintains compatibility across pitch (2.00mm), row configuration (5), mounting type (through hole), and termination method (press-fit). The MP2-H030-51P1-S-KR offers enhanced current rating (1.5A versus 1A) and extended operating temperature range (-55°C to 125°C versus -55°C to 105°C). Selection of this alternative requires verification that the 30-position configuration aligns with system requirements, as it represents a reduction in available signal and ground contacts compared to the 36-position original.

Both substitutes maintain UL94 V-0 flammability rating and MSL 1 moisture sensitivity level. Selection between these options depends on whether exact position count preservation or enhanced thermal and current capabilities are prioritized for the application.

Frequently Asked Questions (FAQ)

Q: Can 84817-501021LLF be used as a direct replacement for 84817-501021?

A: Yes. The 84817-501021LLF maintains identical connector specifications including 36 positions, 2.00mm pitch, 5-row configuration, press-fit termination, and shielded construction. The primary differences are product status (active versus obsolete) and RoHS compliance (compliant versus non-compliant). This is the recommended direct substitute.

Q: What are the key differences between the Amphenol ICC and 3M alternatives?

A: The 84817-501021LLF is a direct Amphenol ICC equivalent with identical position count and specifications. The MP2-H030-51P1-S-KR is a 3M alternative with 30 positions instead of 36, higher current rating (1.5A), and extended temperature range (-55°C to 125°C). Position count reduction must be evaluated against system requirements.

Q: Are all substitute parts RoHS compliant?

A: The 84817-501021LLF and MP2-H030-51P1-S-KR are both RoHS compliant. The original 84817-501021 is RoHS non-compliant. Compliance requirements should be confirmed for your application.

Q: Do the substitute parts maintain the same contact finish specifications?

A: The 84817-501021LLF maintains identical contact finish (Gold or Gold, GXT™) and thickness (50.0µin / 1.27µm). The MP2-H030-51P1-S-KR uses gold finish with reduced thickness (30.0µin / 0.76µm). Contact finish thickness differences may affect long-term reliability in high-cycle mating applications.

Q: What packaging formats are available for the substitute parts?

A: Both 84817-501021LLF and MP2-H030-51P1-S-KR are supplied in tube packaging, suitable for automated assembly processes and component handling.

Q: Can the MP2-H030-51P1-S-KR be used if my system requires 36 positions?

A: No. The MP2-H030-51P1-S-KR provides only 30 positions. This substitute is applicable only when system design accommodates a 30-position connector configuration. For applications requiring 36 positions, the 84817-501021LLF is the appropriate choice.
