Substitute Part Grouping Explanation

Substitution for the 77317-812-08 is determined by the following critical parameters:

Primary Matching Criteria:

Connector type: Header with male pins
Mounting configuration: Through hole, right angle
Position count: 8 positions
Pitch specification: 2.54mm (0.100")
Row configuration: 2 rows at 2.54mm spacing
Termination method: Solder
Current capacity: 3A per contact minimum
Fastening type: Push-pull mechanism
Flammability rating: UL94 V-0

Substitute Classification:

Direct Equivalent: M20-9950445 (Harwin Inc., M20 Series) matches all primary parameters including pitch, position count, row spacing, mounting orientation, and current rating. This part is active status with RoHS3 compliance.

Functional Alternative: 98414-G06-20ULF (Amphenol ICC, Minitek® 2.00mm Series) differs in pitch (2.00mm vs. 2.54mm), position count (20 vs. 8), and row spacing (2.00mm vs. 2.54mm). This part is not a direct substitute due to incompatible mechanical dimensions.

Engineering Selection Recommendations

For Direct Replacement (Recommended):

The M20-9950445 from Harwin Inc. is the appropriate selection for direct substitution of the obsolete 77317-812-08. This part maintains identical electrical and mechanical specifications: 8 positions, 2.54mm pitch, 2-row configuration, right-angle through-hole mounting, 3A per contact current rating, and UL94 V-0 flammability compliance. The M20-9950445 carries active product status with ROHS3 compliance, ensuring long-term availability and regulatory alignment.

Operating Temperature Consideration:

The M20-9950445 operates within -40°C to 105°C, which is narrower than the original part's -65°C to 130°C range. Applications requiring the full original temperature range must evaluate this limitation against specific design requirements.

For Alternative Applications:

The 98414-G06-20ULF is not suitable as a direct substitute due to incompatible mechanical dimensions (2.00mm pitch and spacing versus 2.54mm). This part is applicable only in designs where 2.00mm pitch and 20-position configurations are acceptable.

Frequently Asked Questions (FAQ)

Q: Can the M20-9950445 be used as a direct replacement for the 77317-812-08?

A: Yes. The M20-9950445 matches all critical parameters: 8 positions, 2.54mm pitch, 2-row spacing at 2.54mm, right-angle through-hole mounting, solder termination, 3A per contact current rating, and UL94 V-0 flammability rating. Both parts use push-pull fastening and male pin contacts.

Q: Why is the 98414-G06-20ULF listed as a substitute if it has different specifications?

A: The 98414-G06-20ULF is included as a functional alternative for applications where connector pitch and position count can be modified. It is not a direct mechanical or electrical substitute for the 77317-812-08 due to 2.00mm pitch and 20-position configuration.

Q: What is the impact of the M20-9950445 operating temperature range being narrower than the original part?

A: The M20-9950445 operates from -40°C to 105°C, compared to the original -65°C to 130°C. Applications requiring operation below -40°C or above 105°C must evaluate alternative solutions or confirm that the narrower range is acceptable for the specific use case.

Q: Are there compliance differences between the main part and the M20-9950445?

A: The M20-9950445 is ROHS3 compliant and carries active product status, ensuring regulatory alignment and long-term procurement availability. The original 77317-812-08 is obsolete, making the M20-9950445 the preferred choice for new designs and ongoing production.

Q: What packaging is available for the M20-9950445?

A: The M20-9950445 is supplied in bulk packaging, compared to the original part's unspecified packaging. Confirm packaging requirements with procurement specifications.
